Purpose of Chapter

The purpose of this introductory chapter is to provide the student with an overview of the current nature of international trade in goods and services for the world in general and for the United States in particular. It is useful to make the student aware not only of the broad nature of international transactions, but also of the increased international interdependence that now characterizes the world economy. Although this chapter contains a great amount of “data,” we have found that discussing this kind of information on the first day of class motivates student interest in the subject and in the course in general.

Purpose of Chapter

The purpose of this chapter is to trace out some of the early ideas regarding the basis for international trade and the distribution of the benefits to be gained from trade. The chapter not only provides some historical perspective to trade theory, but it also makes clear why certain contemporary protectionist attitudes can be seen as being based in a Mercantilist view of the world.

Chapter 02 - Early Trade Theories: Mercantilism and the Transition to the Classical World of David Ricardo

A. It is important to focus on the principal tenets of the Mercantilist system and then to examine the policy positions that follow logically. This provides a good background for evaluating various trade policy positions later in the book. B. We feel that this is an excellent time to introduce the labor theory of value. It is a good opportunity to help the student begin thinking in relative terms. It is therefore important that the relative nature of this concept is clear in the students’ minds. C. Once the Mercantilist position is laid out and the economic policy implications discussed, one can examine how Hume’s price-specie-flow mechanism and Smith’s ideas of the mutual gains from trade based on absolute advantage contributed to the decline of the Mercantilist way of thinking. D. Discussing the price-specie-flow mechanism at this point gives the student an early insight into the macro aspect of international trade that often gets short shrift when the micro focus of Classical comparative advantage is introduced.

Answers to End-of-Chapter Questions and Problems

1. Wealth was viewed as synonymous with holdings of precious metals. Nation-states wished to become wealthy and this meant obtaining large holdings of precious metals. It is also argued by some that the shortage of coinage constrained the growth of these nation-states and that precious metals were required to increase the supply of coinage (money) in order for the countries to grow. 2.

Critical pillars of Mercantilism: a. the zero-sum nature of international trade; b. the need for strong, powerful governments; c. the labor theory of value; d. the need to regulate economic activity; and e. the need for a positive trade balance.

Because wealth was viewed in terms of holdings of precious metals, the objective of economic activity and policy was to foster increased holdings of specie. Mercantilists believed that individuals pursuing their own self interest would not accomplish this objective and that, consequently, economic activity had to be closely regulated and supervised. 3. The paradox of Mercantilism is that wealthy countries would contain large numbers of very poor people. A second paradox is that wealthy countries had to spend great amounts of specie to protect their holdings of specie. Wages were kept low (at institutional subsistence levels) to reduce labor costs, and families were encouraged to have children through various taxes and subsidies. These actions contributed to a very large poor working class. 4.

Critical assumptions of the price-specie-flow mechanism: a. a link between the money supply and the price level, e.g., the quantity theory of 2-2

money; b. perfect competition, with flexible wages and prices; c. price-elastic demand for traded goods; and d. existence of a gold standard, with no government interference with the movement of gold and no actions to sterilize gold’s impact on the money supply. If the demand for traded goods were price inelastic, the movement of gold and prices would worsen trade balances, not correct them. This would be destabilizing, not stabilizing. 5. Hume’s price-specie-flow mechanism suggested that a country could not sustain a positive balance of trade because of the effect on money and prices. The external payments position had repercussions on internal economic variables. A continual positive trade balance was thus not a viable policy target, and not a continuous source of increased wealth. Smith’s concept of absolute advantage indicated that both countries could gain from trade, in direct contrast to the Mercantilist’s zero-sum-game view of trade. 6. The United States has an absolute advantage in the production of wheat (3 hrs./unit < 4 hrs./unit) and the United Kingdom has an absolute advantage in clothing (4 hrs./unit < 9 hrs./unit). The United States would gain at the barter price of 1C:2W (1W:0.5C) since it only gets 0.33C for 1W in autarky. Similarly, the United Kingdom would benefit because it takes only 0.5C to obtain a unit of wheat with trade instead of 1C in autarky. 7. (a) In autarky the United Kingdom would produce 75 units of clothing (300 labor hours/4 hrs.) and 50 units of wheat (200 labor hours/4 hrs.). (b) If the United Kingdom allocates all of its labor to clothing production, it will produce 125 units of clothing (500 total labor hours/4 hrs.). United Kingdom consumption of clothing with trade will be the difference between domestic production and exports, i.e., 85 units of cloth. United Kingdom consumption of wheat will be equal to the 80 units of wheat imports it receives for its 40 units of clothing exports [(40 units of exports) (2W/1C)]. Thus, with trade, United Kingdom consumption of clothing increased from 75 to 85 units and its consumption of wheat increased from 50 units to 80 units. 8. (a) In autarky United States wheat production will be 110 units (330 labor hrs./3 hrs.), and cloth production will be 30 units (270 labor hours/9 hrs.). (b) With trade, the United States will consume 120 units of wheat (200 units of production less the 80 units of exports) and 40 units of cloth imports. Consequently, with trade, U.S. consumption of wheat has risen from 110 to 120 units and its consumption of cloth has risen from 30 to 40 units.

Chapter 02 - Early Trade Theories: Mercantilism and the Transition to the Classical World of David Ricardo

In this case trade is a positive-sum game since both parties are able to consume more of both goods with trade compared to autarky, i.e., both countries unambiguously gain from trade. 9. A Mercantilist would view the continuing trade surplus as a very desirable outcome, since it produces a net increase in Chinese holdings of foreign exchange (claims on foreign country assets) which is similar to increased holdings of specie in Mercantilist times. To the Mercantilist, the surplus represents successful Chinese policy, not a problem. Hume would argue that the situation would be self-correcting if a fixed exchange rate system is in place as long as prices and wages are flexible and China does nothing to interfere with the flow of payment and its impact on the money supply. The increase in the money supply accompanying the trade surplus would lead to a relative increase in the prices of Chinese goods, thus reducing the trade surplus. In China’s trading partners, the money supply would decrease and prices would decrease, thus decreasing their deficits. Movement to a zero trade balance would also occur under a flexible-rate system because the trade surplus would lead to an increase in the value of the Chinese currency and therefore to a relative increase in the prices of Chinese goods and services. 10. With a price elasticity of demand of (-) 2.0, a 10 percent increase in price will cause the quantity demanded in Spain to fall by 20 percent [(-2.0) (0.10)]. Because Switzerland was initially exporting 5,000 units, the new level of exports will be 4,000 [(5,000) (1 - 0.20)]. The new value of Swiss exports will be 440,000 francs [(4,000) (110)], which is exactly equal to its new level of imports. The increase in Swiss prices has thus worked to remove its trade surplus with Spain. In the alternative case, with a price elasticity of demand for Swiss exports of (-) 0.2, the 10 percent rise in the price of Swiss goods will cause the quantity demanded in Spain to fall by only 2 percent [(-0.2)(0.10)]. The initial export of 5,000 units decreases by 2 percent of 5,000 or by 100 units, to a quantity of 4,900 units. The new value of Swiss exports to Spain will thus be 539,000 francs [(4,900)(110)]. The Swiss trade surplus with Spain will hence be 539,000 francs – 440,000 francs = 99,000 francs, which is larger than the original surplus of 90,000 francs. The inelastic demand situation has resulted in the price-specie-flow mechanism generating an increase in Switzerland’s surplus, not a decrease. VI.

Teaching Tips

A. This chapter begins with a look at some common myths about international trade. An examination of these myths can be a nice stimulus to class discussion. It is useful to begin with a list of misconceptions about trade that can gradually be dispelled in the coming chapters. B. This chapter should be used to develop a good understanding of comparative advantage. This is perhaps best accomplished by giving the class several different examples of two-country 3-1 © 2014 by McGraw-Hill Education. This is proprietary material solely for authorized instructor use.

by two-commodity examples similar to those in the text, pointing out when there is a basis for trade. C. This is also a good place to drive home the idea that the international terms of trade must lie between the autarky price ratios of the two countries if both countries are to gain from trade. D. After the class is comfortable with the basic idea of comparative advantage, then move on to demonstrate the overall country gains from trade. We find it useful to demonstrate the country gains from trade in two different ways – in a numerical example with fixed resources and with a production-possibilities frontier. E. It is important to demonstrate comparative advantage using the PPF because it not only allows one to generalize beyond the labor theory of value (to opportunity cost in general), but also demonstrates that trade allows a country to consume beyond its PPF. Using the PPF thus provides a good transition between the Classical model and the upcoming neoclassical presentation. V.

Answers to End-of-Chapter Questions and Problems

1.

(a) The autarky price ratios: France: 1 computer:25 wheat, or 1 wheat:1/25 computer Germany: 1 computer:20 wheat, or 1 wheat:1/20 computer (b) France has a comparative advantage in wheat and Germany in computers. France’s disadvantage is relatively smaller in wheat than in computers, i.e., 4/3 < 100/60; Germany’s advantage is relatively greater in computers than wheat, i.e., 60/100 < 3/4. (c) In autarky in France it takes 25 wheat to buy a computer (or 100 days). If it only takes 22 wheat to import the computer, France will save 12 days (= 3 x 4) of labor/computer. In Germany in autarky it takes 1/20 of a computer (3 days) to acquire one wheat. If with trade it only takes 1/22 of a computer (2.73 days)/wheat, Germany saves 0.27 days/wheat import. (d) France saves 4 days of labor/computer; Germany saves 0.5 days of labor/wheat. (e) As the international terms of trade move closer to those of France in autarky, the benefits accruing to Germany increase (e.g., a saving of 0.5 days/wheat instead of 0.28 days), and the benefits accruing to France decrease (e.g., a saving of only 4 days/computer instead of 12 days).

Chapter 03 - The Classical World of David Ricardo and Comparative Advantage

3. In autarky, the production (and consumption) of textiles and autos will utilize all the available 1,000 days of labor. Thus, with T = number of units of textiles produced and A = number of autos produced, 1,000 = (2 days/unit)T + (5 days/unit)A. The consumption requirement is that 10 units of textiles be consumed for every unit of automobiles. Hence, total textile production is equal to (10) (total auto production), i.e., 10A. Thus, given the available labor, and substituting 10A for T, 1,000 = (2) (10A) + 5 A A = 40 units If A = 40 units, then textile production = [1000 - (40)(5)]/[2 days/unit] = 400 units. With specialization in textile production and trade, textile production equals 500 units. Consumption of textiles (CT) is equal to textile production minus the textile exports used to acquire auto imports, and auto imports are equal to auto consumption (CA). With the international terms of trade of 1A:2T, auto imports = (1A/2T)(exports of textiles) = (1A/2T)· (textile production - textile consumption). By the demand assumption, consumption of autos is also equal to (1/10)(textile consumption). Hence, CA = (1/2)(500 - CT) and CA = (1/10)(CT). Thus, (1/2)(500 - CT) = (1/10)(CT) 250 - (1/2)(CT) = (1/10)(CT) 0.6CT = 250 CT = 416⅔ units With CT = 416⅔ units, CA therefore equals 41⅔ units. Because of specialization and trade, the United States has gained 16⅔ units of textiles (416⅔ - 400) and 1⅔ autos (41⅔ - 40) in comparison with the autarky situation. Another method of arriving at these results is to utilize the equations for the PPF and for the consumption pattern. In autarky the PPF equation is T = 500 - 2½A, and the consumption equation is CT = 10CA. Solving the two equations for the two unknowns (there are only two unknowns because A = CA and T = CT in equilibrium) yields A = CA = 40 and T = CT = 400. With trade, the equations to be utilized are for the consumption-possibilities frontier with trade (the trading line) and the consumption equation. The consumption-possibilities frontier with 3-3 © 2014 by McGraw-Hill Education. This is proprietary material solely for authorized instructor use.

trade has the equation T = 500 - 2A. When this equation is put with the consumption equation CT = 10CA and the two equations are solved for the two unknowns, the equilibrium results are A = CA = 41⅔ and T = CT = 416⅔. 4. Classical comparative advantage indicates that when a small price-taking country trades with a large country, the benefits of trade go to the small country. Developing countries may not feel that this is the case due to conditions that violate the Classical assumptions. Examples of these conditions would include such phenomena as imperfect competition, economies of scale in production, different product knowledge, and trade policies such as tariffs, quotas, and production subsidies. 5. Portugal has an absolute advantage in the production of both goods because the absolute labor requirements for both wine and cloth are less than in Spain. However, since the relative labor costs are the same in both countries (4/8 = 6/12), there is no basis for trade based on comparative advantage. Consequently, trade would not take place between the two countries based on either absolute or comparative advantage. 6. Because the price of the import good falls and the price of the export good rises with trade, the slope of the consumption-possibilities frontier originating at the production point is now different from that of the domestic production-possibilities frontier. Trading away from the domestic production point by exporting some of the comparative advantage good and importing the comparative disadvantage good results in the country being able to consume outside the production-possibilities frontier. This is sometimes referred to as the gains from exchange. 7. This could follow from the conclusions reached regarding the distribution of benefits from trade between countries of different economic size. If the impact of the difference in size between the two countries leads to the international terms of trade changing relatively more for the smaller country, then the smaller country will receive relatively more of the benefits of trade between the two. Because the United States is much larger than Mexico, Mexico would receive more of the gains from increased trade accompanying NAFTA as long as the relative change in its prices is greater. However, because the United States is certainly not a “large” country economically or dominant in all of the traded goods and services between the two, both countries should experience some gains from the increased trade and specialization accompanying the trade agreement. 8. This statement could be true if trade was based on absolute advantage. However, since trade can take place on the basis of comparative advantage, what counts is relative cost differences. Consequently a country can be less efficient or become less efficient in all goods and yet gain from trade as long as there are relative cost differences in autarky. Thus, different rates of productivity growth may change what a country exports, but it is unlikely that it would ever take away the basis for trade, i.e., its ability to export.

9. Because country A is more efficient in the production of both goods, its PPF lies outside that of country B. However, if its comparative advantage is in steel, its autarky price ratio will indicate that steel is relatively less costly in terms of wheat, compared to country B, and its PPF will have a steeper slope, i.e., [(PW/PS)country A > (PW/PS)country B].

Suppose that the pre-trade price ratio is 2 grain:5 hardware and that the international terms of trade are 3 grain:5 hardware. Which commodity will the country in question export? Why? What will happen to production in the country under the Classical assumptions? Why? 3. Did the concept of comparative advantage strengthen or worsen the case against Mercantilist trade doctrine? Why? 4. Is it possible for trade to take place in the Classical world of David Ricardo without complete specialization of production in both countries? If so, when? Who will receive the gains from trade in this instance? Why? 5. It is often said that international trade involves both absolute and comparative advantage. Can this be so? Why or why not? 6. Set up a Ricardo-type comparative advantage numerical example with two countries and two goods. Distinguish “absolute advantage” from “comparative advantage” in the context of your example. Then select an international terms-or-trade ratio and explain in some detail how trade between the two countries benefits each of them in comparison with autarky. When would either of your countries NOT benefit from engaging in trade? Explain.

Teaching Tips

A. This chapter begins with a look at the real-world complexities of trade that are omitted from the previous chapter’s discussion. This should help the students to understand the need to 4-1 © 2014 by McGraw-Hill Education. This is proprietary material solely for authorized instructor use.

Chapter 04 - Extensions and Tests of the Classical Model of Trade

examine the extensions of this chapter. B. The key to using this chapter is to make certain that the student can work with and understand the Classical model in money terms. This provides a framework for demonstrating not only additional microeconomic aspects of international trade but also the important role of the exchange rate. The monetized model incorporating the exchange rate makes the international terms of trade explicit and does not just indicate the limits to the terms of trade. C. It is useful to make students comfortable with the idea that the international (barter) terms of trade are simply the reciprocal of the ratio of international prices expressed in a common currency. This will be of value later when working graphically with the neoclassical model. D. Instructors teaching a one-semester course have indicated that they limited the use of this chapter, in particular the discussion of the DFS model. As a result, the DFS model is in an appendix. We have found, however, that working with the remaining extensions helps students develop some good intuition about the nature of international trade. E. We think that the effects of productivity improvement in the DFS model as discussed in the appendix are important for students to grasp. Whether the appendix is used or not, it is useful to stress that productivity improvements in one country do get transmitted to trading partners. The students should be disabused of the zero-sum notion that productivity increases in other countries mean that our country “loses”; rather, real income gains arise not only in the country experiencing the productivity improvement but also in its trading partners. V.

Answers to End-of-Chapter Questions and Problems

1. As a result of the trade surplus, France experiences, under a fixed exchange rate, a net gold inflow and the United Kingdom experiences a net gold outflow. Assuming that the pricespecie-flow mechanism is in operation, these gold movements will result in an increase in prices and wages in France and a decrease in prices and wages in the United Kingdom. Because the demand for traded goods is assumed to be price-elastic, this will cause the expenditures for U.K. goods by France to rise and the expenditures for French goods by the United Kingdom to fall. These adjustments will take place until trade is balanced. The changes in prices in the two countries will lead to a change in the terms of trade that will move them closer to those of the United Kingdom in autarky, i.e., the terms of trade will deteriorate for the United Kingdom and improve for France. 2.

(a) There is a basis for trade here because the relative labor costs for the two commodities are different in autarky, i.e., 6/8 is not the same as 4/4. From another perspective, the individual price ratios in autarky are different between the two countries, i.e., they are 1 wine:0.67 shoes (or 1S:1.5W) in Italy and 1 wine:0.5 shoes (or 1S:2W) in Switzerland. (b) Italy should export shoes and Switzerland should export wine because the relative labor cost of shoes is less in Italy relative to wine. From Switzerland’s point of view, its

Chapter 04 - Extensions and Tests of the Classical Model of Trade

absolute disadvantage is less in wine compared to shoes. (c) The international terms of trade must lie between 1 wine:0.67 shoes and 1 wine:0.5 shoes (or 1S:1.5W and 1S:2W). (d) The commodity terms of trade = 1 wine:(Pwine/Pshoes) shoes [or 1 shoe:(Pshoes/Pwine) wine], which results in 1 wine:(14/24) shoes, i.e., 1 wine:0.583 shoes [or 1 shoe:(24/14) wine, i.e., 1 shoe:1.714 wine]. 3. Given the Swiss wage rate of 3.5 francs per hour and the 1:1 exchange rate, the limits to the wage in Italy are 4⅔ and 3½ euros/hr. Given the Italian wage rate of 4 euros per hour and the 1:1 exchange rate, the limits to the wage in Switzerland are 3 and 4 francs/hr. Given the Italian wage rate of 4 euros/hour and the Swiss wage rate of 3.5 francs/hour, the limits to the exchange rate are 7/8 and 1 1/6 francs/euro. 4. Italy will export shoes and import clothing, wine, cutlery, and fish. Switzerland will export clothing, wine, cutlery, and fish and import shoes. With the inclusion of transportation costs, clothing, wine, and fish become nontraded goods, Switzerland maintains its comparative advantage in cutlery and continues to export it, and the cost of shoes is exactly equalized between the two countries (shoes thus may or may not be traded). The trade pattern changes because the relative costs of the products change when transportation costs are included and assumed to be paid by the importer. In the cases of clothing, wine, and fish, transportation costs exceed the difference in product costs between the two countries and thus cause them to become nontraded goods. 5. There is a basis for trade for all three countries since all three autarky price ratios are different from each other and from the international terms of trade. With an international terms of trade of 1 fish:0.5 potatoes, Sweden and Poland will export potatoes and import fish, and Denmark will export fish and import potatoes.

6. Yes. Since productivity in U.S. manufacturing is considerably higher than in Mexican manufacturing, one would expect the level of wages to be considerably higher in the United States than in Mexico. For traded goods, if U.S. productivity is five times as high but U.S. wages are less than five times as high, U.S. manufactured goods prices would tend to be lower priced than Mexican goods. The relatively great demand for U.S. goods (relatively small demand for Mexican goods) would therefore drive up U.S. wages (and drive down Mexican wages) until the wage difference roughly matches the productivity difference. Similarly, if U.S. wages are more than five times Mexican wages, Mexican goods would be in relatively great demand (and U.S. goods in relatively small demand). Mexican wages would then rise (and U.S. wages would fall) until the wage difference again is roughly equal to the productivity difference.

Chapter 04 - Extensions and Tests of the Classical Model of Trade

In practice, the matter is made more complicated by such factors as nontraded goods and a different composition of goods in the two countries. However, the general principle of the link between relative wages and relative productivity differences still holds. 7.

(a) The relative wage ratio is (WU.S./WU.K.) = [$20/(£8$2/£1)] = 5/4. Thus the United Kingdom exports bread and books; the United States exports VCRs, rugs, and lamps. (b) The upper limit to U.K. wages is found by setting 2/3 = $20/(WU.K.$2/£1); therefore the upper limit to WU.K. is £15 per day. By setting 4/2 equal to $20/(WU.K.$2/£1), the lower limit to WU.K. of £5 per day is obtained. (c) The upper limit to the exchange rate is found by setting 2/3 = $20/(£8e), which yields the result of $3.75/£1. By setting 4/2 = $20/(£8e), the lower limit of $1.25/£1 is obtained.

8.

(a) The new U.K. labor times are: bread - 1.6 days; VCRs - 6.4 days; lamps - 3.2 days; rugs - 2.4 days; books - 1.6 days. With these numbers and the original wage ratio of 5/4, the United Kingdom will export bread, VCRs, rugs, and books; the United States will export lamps. (b) The new upper limit to U.K. wages is found by setting (1.6)/3 = $20/(WU.K. $2/£1); therefore the upper limit to WU.K. is £18.75 per day. By setting (3.2)/2 equal to $20/(WU.K.$2/£1), the lower limit to WU.K. of £6.25 per day is obtained. Thus, with the U.K. productivity improvement, both the upper limit and the lower limit to U.K. wages are higher than prior to the improvement.

9. This is to some extent an opinion question, but deficiencies of the Classical model that could be indicated clearly include the use of the labor theory of value, the constant cost assumption, and the assumption of a smooth monetary adjustment mechanism. The labor theory of value obviously ignores the role of other factors of production in the determination of production cost and hence of pretrade price ratios; the constant cost assumption typically yields the unrealistic situation of complete specialization by both countries; and the lack of a smooth monetary adjustment mechanism in practice means that the actual trade pattern can differ from the comparative advantage pattern. Other deficiencies that could be mentioned that result in a lack of complete realism are the specific assumption that the quantity theory of money holds and the general assumption of the existence of perfect competition. 10. Increases in foreign country productivity will cause the A = a2/a1 curve to shift downward as a2/a1 falls for each good. This will lead to a fall in home country export goods (an increase in foreign country export goods) since the boundary good shifts to the left in the DFS diagram. There will be a decline in the wage level in the home country relative to the foreign country. In addition, following the analysis in the appendix, the foreign country will experience a gain in real income in terms of both home country goods and foreign country goods, and the home country will experience a gain in real income when income is expressed in foreign goods and no change in real income when income is expressed in home goods. Since the home country in fact consumes both home and foreign goods, it thus attains a higher real income. 4-2 © 2014 by McGraw-Hill Education.

Essay Questions

1. In the monetized Classical model, if trade is not balanced, the international terms of trade will deteriorate for the country with the trade deficit. Explain why this is so. 2. In the basic Classical model, only the limits to the international terms of trade can be specified. If the two country-two commodity model is monetized using an exchange rate and a wage rate for each country, the international terms of trade are implicitly specified. Explain why this is so. 3. In a two-country Classical model of trade with many commodities, briefly explain what would happen to the structure of trade in each of the following cases: (a) an increase in wages in one country; (b) a change in the exchange rate; (c) an improvement in productivity (lowering of the labor requirements/product) in one country; and (d) an increase in transportation costs. 4. In a five country-two commodity Classical model of trade, where the autarky price ratios in all five countries are different, can you conclude a priori that all five countries will desire to trade? Why or why not? Between which of the five countries is trade certain? What will determine which of the remaining countries will trade? 5. It is common to read statements to the effect that domestic inflation or production cost increases hinder our ability to export and also stimulate imports. Is this consistent with the Classical view of international trade? What effects would such an event have on the overall economy according to Classical thinking? 6.

(a) Set up a Ricardo-type comparative advantage numerical example with two countries and two goods. Distinguish “absolute advantage” from “comparative advantage” in the context of your example. Then explain how trade between the two countries benefits each of them in comparison with autarky. (b) For your numerical example in part (a) of this question, assign a wage rate to one of your countries and a fixed exchange rate between the two currencies. Then, using your wage rate and the exchange rate, indicate the upper and lower limits to the wage rate in the other country that are consistent with two-way trade between the countries, and explain why these are the upper and lower limits.

(a) “If country A can produce all goods with less labor time per unit of output than can country B, then there can be no reason for country A to trade with country B – country A would always maximize its own welfare by satisfying its consumption desires for all goods from its own production.” (b) “If country I’s workers have greater productivity in all industries than country II’s workers, then workers in country I will be paid a higher wage rate than workers in country II.” 8. Set up a Ricardo-type comparative advantage numerical example with two countries and two goods. Explain how trade between the two countries can benefit each of them in comparison with autarky. Then indicate a situation in which only one of the two countries would gain from trade and carefully explain why only one country gains. (Question 9 pertains to appendix material.) 9.

(a) Explain the Dornbusch-Fischer-Samuelson (DFS) model of Classical-type trade between two countries in a very large number of goods. Be sure to describe why each curve slopes as it does, and indicate the trading pattern at the equilibrium position. (b) Now suppose that, from your equilibrium position in part (a) above, there is a uniform improvement in labor productivity in one of the two countries in all industries. (You can choose either country.) Illustrate and explain what happens to the trading pattern and to relative wage rates. Then explain the impact of the productivity improvement on real income in each country.

Purpose of Chapter

Since neoclassical trade theory at the undergraduate level relies heavily on a few basic graphical micro tools, we think it useful to gather these tools into one convenient place early in the book. The purpose of the chapter is to re-introduce the student to thinking in marginal terms and to re-emphasize principles of maximization. The student should become aware early in the course that the conceptual precision of economic analysis to which he or she was exposed in earlier work is going to be employed in the international trade course as well.

Teaching Tips

A. In classes where the prerequisite for the international economics course(s) consists only of introductory economics, some of the tools will be new and this chapter should be required reading. If intermediate micro is a prerequisite, this chapter can be made optional, but it may still serve as a worthwhile reference point if difficulty is encountered in later chapters. Even then, however, the material on community indifference curves is likely to be new to the students. B. Our less-than-complete discussion of relative factor intensity of production processes can be given more precision in class here rather than waiting until that material is more fully developed in Chapter 8. C. In the discussion of consumer and producer maximization we think that the student’s grasp of the material is improved if the tangencies and equalities and the movements to them are not thought of as relationships to be memorized but rather as processes to be understood in economic terms. Thus, we stress that, with a disequilibrium such as (MUX/PX) > (MUY/PY), it is simple common sense to reallocate the consumption bundle toward more of good X and less of good Y because total utility is enhanced through spending the last dollar on a good that brings greater utility at the margin. D. The material on the derivation of the PPF from the Edgeworth box at the end of the chapter seems particularly useful to us when we teach the course, and we recommend that special emphasis be put upon it. This material is helpful for the later discussion in Chapter 8 of the Heckscher-Ohlin trade pattern when using the physical definition of factor abundance. E. If students have a ready grasp of the Edgeworth box and if time permits in a one-semester trade course, you might want to derive a community indifference curve from a consumption Edgeworth box by selecting a starting point on the contract curve and “sliding” one consumer’s individual curve along the other’s curve so that the origin that is changing traces out a community curve. Different starting points can then be shown to yield intersecting curves unless assumptions are made that both consumers have: (a) the same (or proportional) incomes and identical tastes; (b) identical and homothetic tastes; or (c) the same (or proportional) incomes and homothetic tastes.

Answers to End-of-Chapter Questions and Problems

1.

In the graph below,

the initial equilibrium is at point E1 with relative prices (PX/PY)1. If the price of good X falls while the price of good Y remains constant, then a new flatter price line (PX/PY)2 line emerges from the original intercept at point A on the vertical axis. Because MUX/PX is now greater than MUY/PY at E1, the consumer will substitute toward greater consumption of the X good and less consumption of the Y good in order to increase total satisfaction. Equilibrium will move from E1 to E2, and the consumer will be on a higher indifference curve and will have increased the relative consumption of good X. Only if good X is a sufficiently “inferior” good will the relative increase in the quantity of X consumed not occur. 2. Consider an indifference curve diagram such as Figure 3 in the text. A shift in the income distribution toward consumers with a relatively stronger preference for good Y than in the original distribution (the distribution with the solid lines) will make each curve “flatter” and will shift each curve leftward toward the vertical axis. The curves become flatter because, for any total amount of Y taken away from consumers at the margin in proportion to their incomes, more X must be given to the community as a whole in order to restore each consumer to his or her original level of satisfaction. The leftward shift occurs because, at each given total amount of good Y consumed (which is now more preferred), less X is necessary in order for the community as a whole to attain a given utility level. 3. In Figure 8 in the text, consider the lower intersection point (not labeled) of isoquant Q0 with budget line B1. At that point, MPPL/MPPK is less than w/r because the isoquant is flatter than the isocost line. This indicates that MPPL/w < MPPK/r, or that, at the margin, the output obtained per dollar spent on labor by the firm is less than the output obtained per dollar spent on capital. The profit-maximizing entrepreneur will therefore, with the given budget, reallocate spending toward capital and away from labor. The reallocation will stop at point E, where, at the margin, the output per dollar spent on capital is equal to the output per dollar spent on labor. The higher isoquant Q1 will have been reached, and equality between MPPL/MPPK has been achieved by a rising MPPL as less labor is utilized and a falling MPPK as more capital is utilized. 4. No, it cannot be unambiguously determined. With capital on the vertical axis and labor on the horizontal axis, the new flatter isocost line will have a vertical-axis intercept lower than originally and a horizontal-axis intercept to the right of the original intercept. If this new isocost line passes above the original equilibrium point, the new level of output will be greater than it was before the factor price changes; if it passes below the original point, output will have fallen. 5-3 © 2014 by McGraw-Hill Education.

5. With labor on the horizontal axis and capital on the vertical axis, the original isocost line has a vertical-axis intercept of 300 hours of capital usage and a horizontal-axis intercept of 3,000 hours of labor usage. The slope of this isocost line is (-)1/10 or 0.10. With the specified changes in factor prices, the isocost line shifts inward on both axes because the prices of both inputs have increased. The new intercepts are at 250 hours of capital and 2,000 hours of labor, and the new isocost line is slightly steeper [having a slope of (-)12.5/100 or 0.125] than the old one. The equilibrium level of output has fallen because all inputs have risen in price; the firm has also shifted toward using more capital relative to labor because w/r has risen. 6. The PPF would exhibit constant opportunity costs. Suppose that the employment of all of the economy’s capital and labor in the X industry (an endpoint of the Edgeworth box diagonal) yields 100 units of X output (and 0 units of Y output). Alternatively, suppose that employment of all capital and labor in the Y industry yields 200 units of Y output (and 0 units of X output). With constant returns to scale in both industries, production at the midpoint of the diagonal (using one-half of the economy’s capital and labor in each industry) would therefore yield 50X and 100Y. Employment of one-fourth of the economy’s capital and labor in the X industry and three-fourths of the economy's capital and labor in the Y industry (i.e., at a point one-fourth of the distance along the diagonal from the X origin to the Y origin) would yield 25X and 150Y. Plotting these various output combinations (and the output combinations of all other production points on the diagonal) yields a straight-line PPF. This PPF would be analogous to the dashed line RTMWQ in Figure 13(b) in the text. 7. This statement is incorrect. The discussion in the text regarding the productionpossibilities frontier indicates that a PPF with increasing opportunity costs emerges when constant returns to scale exist in each industry, provided that the industries have different factor intensities. Thus, neither industry needs to be operating in a context of decreasing returns to scale in order to generate an increasing-opportunity-cost PPF. 8. The country is producing less of the capital-intensive good and more of the laborintensive good. The overall demand for labor would rise and the overall demand for capital would fall as the industry with the higher K/L ratio (lower L/K ratio), industry Y, contracts, while the industry with the lower K/L ratio (higher L/K ratio), industry X, expands. Hence, relative factor prices w/r will rise (or r/w will fall). No, the (absolute values of the) isoquant slopes at V’ will be higher than at S’ because, in equilibrium, these (absolute values of the) slopes are equal to the now-higher w/r. An alternative geometric explanation is that, with homothetic isoquants, a ray from 0X (0Y) through S’ would hit isoquant x2 (y4) at a point below and to the right (above and to the left) of V’, a point that would have the same slope as isoquant x1 (y6) at S’. Given the convex shapes of isoquants, V’ would then have a steeper slope than S’. 9. The Edgeworth box would become “taller” because the vertical capital axes become longer and the horizontal labor axes stay the same length. The PPF will also become “taller” because the good Y intercept shifts upward by a greater percentage than the good X intercept shifts rightward. Note, however, that the good X intercept does shift to the right because, with a larger capital stock, more X can be obtained when all resources are devoted to X production.

10. If the price of labor rises with no change in the price or rental rate of capital, w/r increases (r/w decreases). Producers in both industries would respond by using relatively less labor and relatively more capital, and the K/L ratio would rise in both industries. Note that, in this question, we do not specify the cause of the rise in the price of labor – the effects on output of each good and on total output would depend on this cause and would be different, for example, if the cause were technological change that increased the demand for labor rather than a desire on the part of labor to take more leisure time.

Essay Questions

1. Suppose that, from an initial individual consumer equilibrium position in the indifference curve-budget line diagram, the prices of both goods rise by 10 percent. What happens to the position and slope of the budget line? Why does the consumer’s level of satisfaction from a given money income fall? Illustrate and explain. Would it be acceptable for an economist to say that the level of satisfaction of the consumer fell by exactly 10 percent? Why or why not? 2. Suppose that, from an initial individual consumer equilibrium position in the indifference curve-budget line diagram, the price of good X rises while the price of good Y falls. What will happen to the relative consumption of the two goods by the consumer and why? Can it be specified whether the consumer’s level of satisfaction has increased or decreased because of this change in absolute and relative prices? Why or why not? Could the satisfaction level of some consumers increase and the satisfaction level of other consumers decrease because of the price changes? Explain. 3. “If constant returns to scale exist for a firm, then a 10 percent rise in all factor prices will lead to a 10 percent decline in the equilibrium quantity of output for a given budget. However, if increasing returns to scale exist, a 10 percent rise in all factor prices will lead to a less than 10 percent decline in the equilibrium quantity of output for a given budget.” Assess the validity of this statement. 4. Explain, using the isoquant-isocost diagram, why a rise in the rental rate of capital coupled with no change in the wage rate will lead to a rise in the price of the capital-intensive good relative to the price of the labor-intensive good. 5. Explain why any point on an economy’s PPF must be associated with a point on the production efficiency locus in the Edgeworth box diagram.

Purpose of Chapter

The purpose of this chapter is to build the case, using familiar microeconomic tools, for a country to participate in international trade rather than to remain in autarky. The chapter thus uses more modern or updated analysis, compared to the Classical model, to evaluate the impact of trade. The chapter also attempts to acquaint the student with some of the important underlying assumptions in this neoclassical analysis. IV.

Chapter 06 - Gains from Trade in Neoclassical Theory

A. The chapter begins with an analysis of the costs of trade restrictions in terms of lost imports and exports. This provides students with a real-world estimate of the potential gains from free trade as a motivation for the theoretical discussion in this chapter. B. We find it useful to dwell on the production equilibrium material, since students don’t usually seem to have an economic grasp of why the equilibrium production point on the PPF emerges in the standard competitive framework. C. When introducing the effects of international trade it is worthwhile to stress that the “trading line” is in fact the consumption-possibilities frontier (CPF) with trade. This CPF is outside the economy’s CPF in autarky (which is identical to the PPF), except at the point of tangency to the PPF. D. The consumption gain from trade sometimes puzzles students. It can be useful to explain this gain as the natural result of receiving a relatively higher price for the good now sold on the world market, coupled with paying a relatively lower price for the good now bought on the world market. E. It can be helpful in discussing the case of identical PPFs and different tastes to emphasize that the gains for each country occur because they are each getting more of the good for which they have relative preference. However, note that trade does not occur because of the different tastes per se but rather because of the different opportunity costs resulting from the different tastes in the increasing-opportunity-cost framework. F. The discussion in the last section regarding underlying assumptions seems to be of interest to students. It is useful to stress that policies that facilitate mobility and adjustment to trade (such as trade adjustment assistance), as well as possible compensation measures, can help to ensure that the actual gains from trade are maximized in practice. V.

Answers to End-of-Chapter Questions and Problems

1. Figures 1 and 2 in the text are the relevant diagrams. Point E is the production equilibrium position because the marginal rate of transformation in production (= marginal cost of X/marginal cost of Y) is equal to the relative commodity price ratio PX/PY at that point. For the given relative prices, production at any other point would have PX/PY unequal to MCX/MCY, or PX/MCX unequal to PY/MCY. Hence, firms would have an incentive to shift resources until point E was attained. For consumers, point E in Figure 2 is the equilibrium position because, at that point, the marginal rate of substitution in consumption (= marginal utility of X/marginal utility of Y) is equal to PX/PY. Consumption on the PPF at any other point would be on a lower indifference curve, and, for the given prices, MUX/MUY would be unequal to PX/PY (or MUX/PX would be unequal to MUY/PY). Because consumption of one good at the margin brings less utility per dollar spent than on the other good, consumers will change their consumption bundle until point E is attained.

Chapter 06 - Gains from Trade in Neoclassical Theory

In order for the country to gain from trade, the world PX/PY must be different from the autarky PX/PY. With different relative prices on the world market, a reallocation of production and consumption will enable the country to move to a higher indifference curve. 2. Yes, the country should trade. It should export cloth because that is the good of comparative advantage, and producers will have a profit incentive to sell cloth at its relatively higher price on the world market. The country will gain from trade because its trading line (CPF with trade) will permit larger consumption bundles than are possible in autarky, since the exported cloth allows for the purchase of relatively cheaper machines than in autarky. As long as world prices differ from autarky prices, the country can move to a higher indifference curve by participating in trade. 3. The “gains from exchange” (“consumption gain”) occur because of the opportunity to consume at different relative goods prices, even though production does not change. The higher relative price for the export good on the world market permits consumption of the now-relatively lower priced import good, and consumers will substitute toward the import good and will move to a higher indifference curve than was possible in autarky. The “gains from specialization” (“production gain”) reflect the enhanced real income possible for the economy because the economy is now using resources more efficiently by concentrating its production to a greater extent on its comparative advantage good. 4. Yes. Even though unemployment may not fall with the opening of the country to trade, the country can still be reallocating production (increasing the proportion of employed workers in the export industry and decreasing the proportion in the import-substitute industry) and can trade along a CPF different from the CPF being attained in autarky. The consumption and production gains from trade can still be realized. In fact, consumption could now even occur outside (rather than inside) the PPF with a sufficient volume of trade. Further, even if no workers can be shifted to the export industry from the import-substitute industry (or from the unemployment pool) because of rigidities, the consumption gain from trade will still occur. 5. The statement is incorrect. This is the case of trade with a “right-angle” PPF. The consumption gain from trade will still be realized because trade has exposed the country to a different set of relative commodity prices. 6. Without getting into material generally beyond the scope of the undergraduate course (such as the conditions discussed in the Tower article cited in the text or in Miltiades Chacholiades, International Trade Theory and Policy, Chapter 5), the general statements regarding the indifference curve map and welfare changes found in the section entitled “The Indifference Curve Map Can Show Welfare Changes” can be used to answer this question. 7. This position reflects a misunderstanding of the nature of the gains from trade. With trade, both countries become better off in that movement can take place to a higher community indifference curve in each nation. Certainly U.S. producers in industries that would now compete with Cuban exports (principally sugar) would be injured, but U.S. consumers of sugar would gain, as would U.S. producers of new exports to Cuba (such as machine tools).

Chapter 06 - Gains from Trade in Neoclassical Theory

chapter has explained, if the compensation principle is employed, those who gain from trade can fully compensate all losers and still be better off because a larger quantity of goods is available. Of course, relaxation of the embargo involves political dimensions as well as economic dimensions, and these noneconomic aspects need to be taken into account when deciding upon the most desirable course of action. 8. It is not likely that trade would cease even if production conditions were to become identical (identical technologies and relative factor endowments). This is because there would still be a basis for trade as long as demand conditions (as reflected in the two community indifference maps) continued to be different for the two countries. 9. While the opening of trade improves the overall well-being of a country, it can affect the distribution of real income and leave certain individuals less well off. This result occurs because the price of the export good is rising, the price of the import good is falling, and factor prices are changing. In this case, Ms. Jones is correct about her situation but not about the situation of the country. Also, as will be seen in Chapter 8, if Ms. Jones owns the abundant factor used intensively in food production (the export), her real income should be rising because the price of the abundant factor rises to a greater relative extent than does the price of the export good (via the Stolper-Samuelson theorem and the magnification effect). In this instance, her conclusion about her own situation is incorrect. If, however, she owns the scarce factor of production, she will be strictly worse off since she will be faced with both an increased price of food and a falling income due to the decline in the price of the scarce factor. If Ms. Jones falls into the latter category, she should lobby for “compensation” from those whose real income has clearly increased from trade rather than for the imposition of trade restrictions which would lead to a fall in real income for the economy as a whole. 10. Even though a change in the indifference map makes it impossible to compare the new and old indifference curves in a meaningful way, it is still possible that a conclusion regarding the gains from trade can be reached by comparing the old consumption bundle with the new consumption bundle. If a country is consuming more of both goods after trade or the same amount of one good and more of the other it can be concluded that the country is better off with trade. This conclusion rests on the long-held axiom that more is preferred to less. However, if trade involves moving to a consumption point which involves having more of one good and less of the other, a clear ambiguity exists. Such an ambiguity can potentially be removed, however, if by changing the trade bundle, the country can move to a consumption situation where winners could compensate losers and where no one is worse off and at least one person is better off. See the appendix for more discussion.

Sample Exam Questions

A.

Essay Questions

1. In the equilibrium trading position in a two-country model of trade, why must the trade triangles of the two countries be congruent (identical)? What role does the slope of the world price line play in making the triangles congruent? 2. The text has demonstrated that, even if a country’s production does not change with the opening of the country to trade, a gain (the “consumption gain”) can still occur even though there is no “production gain.” Is the reverse situation possible – that is, can there be a “production gain” without there being a “consumption gain” for the country? Why or why not? 3.

“In a situation of increasing opportunity costs, trade can be beneficial to both countries if they have identical PPFs or if they have identical tastes. However, trade cannot be beneficial to either country if the countries have identical PPFs and identical tastes.” Is this statement correct or incorrect? Illustrate and explain.

4. (This question pertains to material in the appendix.) Explain the economist’s distinction, in discussion of the compensation principle, between “potential” gains from trade and “actual” gains from trade. Why are the gains only “potential” when that word is used? 5. Suppose that the trade pattern of a country is that it exports foodstuffs and imports fancy sports equipment. Can you make a case that trade acts like a regressive tax in its impact on the distribution of real income and welfare within the country? Explain. 6. Explain, using the PPF-indifference curve diagram, how a change in tastes can cause a country to shift from being an exporter of a good to being an importer of that same good. (Assume that world prices are constant.) 7. (a) Using the neoclassical model, build the case why it is beneficial for a country to move from a situation of autarky to a situation of free trade. (b) Briefly, why can the neoclassical model of trade be regarded as “better” in some respects than the Classical model of trade?

8. Illustrate and explain, for each statement below, why the statement is either TRUE or FALSE. Assume a two-commodity world in each case. (a) “If a country has an absolutely fixed production pattern, i.e., resources used in each industry are completely specific to their respective industry, then this

country cannot experience any welfare gain when moving from autarky to free trade.” (b) “It is possible that, even if two countries have identical productionpossibilities frontiers, trade between the countries can enhance the well-being of each country, in comparison with well-being under autarky.” 9.

(a) Suppose that two countries have identical increasing-opportunity-costs productionpossibilities frontiers (PPFs). Illustrate and carefully explain why, under certain conditions, the two countries can have an incentive to trade with each other. In addition, illustrate and explain how they can therefore both gain from trade. (b) Suppose that two countries, in a situation where they each have an increasingopportunity-costs production-possibilities frontier (PPF), have identical tastes and preferences (demands). Illustrate and carefully explain why, under certain conditions, the two countries can have an incentive to trade with each other. Why can they gain from trade?

10.

(a) Using the neoclassical production-possibilities frontier/indifference curve approach, build the case that free trade is preferable to autarky for a country. Then explain how an economist could still say that trade can be beneficial to the country even if trade causes the community indifference curve map to change such that the country appears to lose welfare on the basis of the original autarky income distribution. (b) It has often been pointed out in this course that, within a country, a movement to freer trade, while helping some people, can hurt other people. Thinking over various parts of this course, indicate two groups of people within a country who can have their well-being reduced because of the opening of the country to trade and very briefly explain why their welfare can be reduced.

Purpose of Chapter

The purpose of this chapter is to introduce students to the concept of the offer curve and to the determination of the equilibrium international terms of trade. A general overview of the chapter is that, until this point in the book, the establishment of the equilibrium terms of trade has not been analyzed: now the student can see how the terms of trade result from the interaction of supply and demand in the world market.

Chapter 07 - Offer Curves and the Terms of Trade

IV.

Teaching Tips

A. Offer curves are often viewed by students as difficult and theoretical. The introduction to this chapter presents the impact of changes in the supply of exports or demand for imports on terms of trade for a group of African nations. The impact of these changes in terms of trade on real income is also presented. This is designed to provide additional motivation for the students to understand how terms of trade are determined and why they change. B. The offer curve and the terms of trade are used extensively in later chapters, so the foundation established in this chapter is very important. We find it useful to stress that, unlike other concepts to which the students have been exposed, the offer curve is both a supply curve (of exports) and a demand curve (for imports). C. The “tabular approach” to deriving an offer curve developed in Concept Box 1 seems to be interesting to students. It is also useful because it drives home the point about the offer curve being both a supply curve and a demand curve. In addition, adding another row or two to the table with appropriately-chosen numbers can yield a “backward-bending” offer curve that is understandable. D. The nature of the shifts in Country II’s offer curve discussed and illustrated on page 113 should be emphasized. For some unknown reason, students often seem to think that an “increased willingness to trade” by the country whose exports are on the vertical axis means a pivot of that country’s curve downward and to the right. E. The use in class of the latest export and import price indexes from the IMF’s International Financial Statistics to demonstrate calculation of the commodity terms of trade seems to be of interest to students. F. We’ve never quite puzzled out why, but some students often seem to confuse “terms of trade” with “balance of trade.” It is useful to distinguish between these very different concepts. V.

Answers to End-of-Chapter Questions and Problems

1. A change in tastes by the home country’s consumers toward greater relative preference for the import good would increase the willingness of the country to trade. In addition, a rise in income (provided that imports as a whole are not “inferior goods”) would also make the country more willing to trade at each terms of trade. Other events leading to greater willingness to trade would be, for example, increased productivity in the export industry and trade negotiations that resulted in a lowering of trade barriers by the home country. 2. If the demand increase for the export good is by the foreign country, the terms of trade will improve by an equal amount in either instance. If the country is large, the normal upward shift in the foreign offer curve occurs; if the country is small, the straight-line offer curve by the foreign country pivots to higher terms of trade for the home country. If the demand increase for the export good is by home country citizens, the home country’s offer curve pivots inward. If the

Chapter 07 - Offer Curves and the Terms of Trade

country is large, the terms of trade will improve, but, if the home country is small, there will be no impact on the terms of trade since a small country faces a foreign offer curve that is a straight line from the origin. 3. The terms of trade for country I will definitely deteriorate, since both shifts are working in that direction. However, the impact on the volume of trade is indeterminate without more information. Assuming that country I is operating in the “elastic” portion of its offer curve, the increased willingness to trade by I will lead to an expansion of both its exports and imports (if country II is operating on the “elastic” portion of II’s curve) and to an expansion of I’s exports and a contraction of I’s imports (if country II is operating on the “inelastic” portion of II’s curve). The reduced willingness to trade by country II will lead to a contraction of both the exports and imports of country I regardless of the elasticity range of II’s curve. The net effect on I’s exports is indeterminate always and depends on the relative extent of the offer curve shifts; the net effect on I’s imports is indeterminate if country II is operating in its “elastic” range and a decline if II is operating in its “inelastic” range. If country I is operating in the “inelastic” portion of its offer curve both before and after the two shifts, the result will be a greater volume of exports by I if II’s curve is “elastic” but export volume could be less if II is in its “inelastic” range; the volume of I’s imports can either increase or decrease with either range of II’s curve. (We assume that the equilibrium positions are “stable” equilibria and, of course, that both countries are “large” countries. You may also wish to assume for your class, as we usually do, that both countries always operate in the “elastic” ranges of their offer curves, which makes the answers to this question and to Question #4 below considerably simpler.) 4. With both countries operating in the “elastic” ranges of their offer curves, the volume of country I’s exports and imports will definitely decrease. However, the terms of trade impact (under all elasticity assumptions) is indeterminate without more information. Country I’s decreased willingness to trade will improve its terms of trade, but country II’s decreased willingness to trade will cause deterioration in I’s terms of trade. The net impact therefore depends on the relative extent of the offer curve shifts. If country I is operating in the “inelastic” portion of its offer curve, the volume of its imports decreases but the volume of its exports can increase if country II is in its “elastic” range. If country II is also operating in the “inelastic” portion of its offer curve, the volume of I’s exports will decrease but the volume of I’s imports can actually increase. 5. The excess supply of exports of one good (say good X) means that, at the given terms of trade, one country (say country I) is willing to provide a greater quantity of good X on the world market than country II is willing to purchase at those terms of trade. PX/PY (with Y being II’s export good) is thus higher than the equilibrium terms of trade. Because PX/PY is “too high,” this must mean that PY/PX is “too low” or below the equilibrium level. A relative price of good Y below the equilibrium level means that there is excess demand for good Y. Alternatively, because a supply of exports reflects a demand for imports in the offer curve analysis, a supply of good X from I that exceeds the demand for good X by II must be associated with a demand for good Y by I that exceeds the supply of good Y coming forth from country II at the given terms of trade.

6. In the offer curve diagram below, the initial trading equilibrium between Iraq and the rest of the world (ROW) results in terms of trade TOT1. With the greatly reduced willingness to trade by ROW, the ROW offer curve shifts downward to ROW’. The terms of trade for Iraq deteriorate to TOT2, and the volume of Iraq’s exports and imports falls dramatically. If Iraq is in the “inelastic” portion of its offer curve both before and after the ROW curve shift, Iraq could actually end up exporting a larger volume, but this situation is highly unrealistic.

7. With relatively slow growth in demand for developing countries’ products by developed countries, the developed countries’ offer curve shifts only slightly upward. With relatively rapid growth in demand by the developing countries for developed countries’ export goods, the developing countries’ offer curve shifts rightward to a relatively large extent. The terms of trade deteriorate for the developing countries. If it were postulated that the developed countries were in the “inelastic” range of their offer curve, the developing countries would experience an even greater deterioration in their terms of trade. (It is highly unlikely that the developing countries have an inelastic demand for developed countries’ goods, so that case does not need to be considered.)

8. The offer curves of the oil-importing countries were likely inelastic because the rise in the price of oil exports by OPEC resulted in greater “revenue” (export quantity in the offer curve diagram) being spent on the crude petroleum imports by any given importing country. Hence, the oil importers were in the “backward-bending” portions of their offer curves. 7-2 © 2014 by McGraw-Hill Education. This is proprietary material solely for authorized instructor use.

9. “Behaving rationally” occurs even with a “backward-bending” offer curve. The underlying economic purpose of exports is to obtain imports for enhancing utility, and a rise in the relative price of exports constitutes a fall in the relative price of imports. With this fall in the price of imports, there will rationally be a rise in the quantity of imports purchased, and the exporting country will export a smaller quantity if the demand for imports is inelastic. Alternatively, the rise in the price of exports would lead to the export of a smaller quantity if the “income effect” (or “terms-of-trade effect”) of the price increase outweighs the “production effect” and the “substitution effect.” 10. The commodity terms-of-trade ratio for 2010 is 92.3 [= (120/130)100]; the income terms of trade for 2010 are 106.2 [= (120115)/130]. Thus the commodity terms of trade deteriorated from 2000 to 2010 while the income terms of trade improved. This could certainly occur if the relative decline in export prices stimulated an elastic response of quantities demanded of the country’s exports. VI.

Essay Questions

1. Suppose that a home country is contemplating the imposition of a tariff in order to improve its terms of trade by a given amount. How would the decision as to the size of the tariff to impose depend on the elasticity of the foreign country’s offer curve? Explain. 2. Suppose that, from an initial equilibrium position in the offer curve diagram, country I imposes a tariff on country II’s export good at the same time that consumers in country II change their tastes toward wanting more of II’s export good. Illustrate and explain the impact of these two simultaneous events on country I’s volume and terms of trade. (Assume that both countries’ offer curves are “elastic” throughout.) 3. When Spain and Portugal joined the European Community (EC) in 1986, the United States feared that a result of this change might be a shift in demand for agricultural products by Spain and Portugal away from the United States and toward other Community members. In response, the United States threatened to impose stiff tariffs on a variety of exports of the rest of the EC to the United States. Using offer curve diagrams for (a) the United States and Spain/ Portugal, (b) Spain/Portugal and the rest of the EC, and (c) the United States and the rest of the EC, illustrate and explain the effects of these potential events on the terms of trade and volume of trade for the various economic units.

What is the nature of the elasticity of demand for imports between [i] points (a) and (b); [ii] points (b) and (c); and [iii] points (c) and (d)? How do you know? What might account for these respective elasticities? 5.

Given the following indexes for country I in 2012, with 2005 = 100: price of exports = 108

quantity of exports = 116

price of imports = 120

quantity of imports = 102

(a) Calculate country I’s net barter or commodity terms of trade for 2012 (round to nearest one decimal place if necessary). (b) Calculate country I’s income terms of trade for 2012 (round to nearest one decimal place if necessary). (c) Explain your differing results for (a) and (b) and briefly explain the significance of each terms-of-trade movement for country I. 6.

“If we observe that a home country’s volume and terms of trade are both moving in the same direction (i.e., either both increasing or both decreasing), then we can surmise that the home country’s offer curve is shifting. However, if we observe that the home country’s volume and terms of trade are moving in opposite directions (i.e., one is increasing and the other is decreasing), then we can surmise that the foreign offer curve is shifting.” Is this statement correct or incorrect? Illustrate and explain your answer. (Assume “elastic” offer curves throughout.)

Chapter 07 - Offer Curves and the Terms of Trade

7. (a) Define the “offer curve” (or “reciprocal demand curve”) of a country. If an offer curve is drawn as an upward-sloping curve, what is being assumed about the value of the country’s elasticity of demand for imports and why does this assumption yield the upward-sloping curve? (b) Using the usual two-good, two-country offer-curve diagram, identify the equilibrium position and state why the position is one of equilibrium. Then suppose that, from this initial equilibrium position, one country now experiences an increase in productivity in its export industry at the same time that the other country imposes an import tariff. Illustrate and explain the combined or overall impact of these two events on the equilibrium terms of trade and on the quantity traded of each of the two goods. If a combined impact is uncertain, briefly indicate why it is uncertain. 8.

(a) Define the theoretical concept of a country’s “offer curve” (or “reciprocal demand curve”). Then, using a numerical example, construct three points on a country’s offer curve, assuming that the country (call it “country A”) exports wheat and imports clothing. (b) Put the offer curve of country A [you do not need to use your specific numbers from part (a) of this question in this part (b)] together with the offer curve of trading partner country B. Explain how the equilibrium position is attained if the countries initially are in a situation that is not a position of equilibrium. (You can assume that the countries are always operating in the “elastic” portions of their offer curves.) (c) Finally, suppose that country B’s consumers change their tastes so that they now have greater preference for country A’s export good than they did previously. Illustrate and carefully explain the movement from the old equilibrium position to the new equilibrium position because of this change in tastes, assuming other things equal. Be sure to include an indication of the impact on country A’s terms of trade and volume of trade.

9.

(a) Define the concept of a country’s (call it country A’s) offer curve. Will this curve always be upward-sloping? Briefly, why or why not? (b) Put country A’s offer curve together with the offer curve of a trading partner country (call it country B) and indicate the equilibrium position. Then suppose that, from this equilibrium position, country A’s consumers now change their tastes toward wanting relatively more of A’s export good at the same time that country B reduces its tariff on A’s export good. Explain the impact of each event separately on the volume of trade of each good and on the terms of trade. Then indicate whether it is possible to assess, when the new equilibrium position is attained, the net results of the two shifts together on the volume of trade of each good and on the terms of trade (in comparison with the initial equilibrium). (Assume that the offer curves are “elastic” throughout.)

Chapter 08 - The Basis for Trade: Factor Endowments and the Heckscher-Ohlin Model

III.

Purpose of Chapter

The purpose of this chapter is to explain the underlying bases for trade, i.e., to explain the existence of different relative autarky prices in different countries. Particular attention is paid to factor endowments, factor intensities, the Heckscher-Ohlin theorem, the factor-price equalization process, and qualifications to the Heckscher-Ohlin explanation. IV.

Teaching Tips

A. The chapter begins with an examination of labor standards in developing countries. The article chosen investigates the possibility that a developing country can increase its relative abundance of unskilled labor by lowering labor standards, thereby enhancing a comparative advantage. This is a nice starting point for students because it uses a relatively controversial current issue to expose them to the concept of relative factor abundance and examines its potential impact on comparative advantage. B. In teaching the Heckscher-Ohlin paradigm and the resulting trade theorems, it is extremely important to lay out carefully the central assumptions of the model. In particular, it is crucial that students understand the concept of relative factor abundance from both the physical and price perspectives. It is useful to emphasize that the two definitions will necessarily give the same ranking of factor abundance only when demand is identical in the two countries. C. The second critical assumption to emphasize is the assumption of identical relative factor intensity across commodities. Students often do not grasp the idea that according to this assumption, commodities have the same relative factor intensity regardless of where they are produced in the world. D. Once the basis for trade (the Heckscher-Ohlin theorem) has been established, focus on the nature of the adjustment process that will accompany the opening of trade between the two countries. In discussing the factor-price equalization theorem, we have found it useful to point out that goods movements between countries substitute for factor movements, with the same impact on factor prices. E. We encourage you to spend some time on the income distribution effects of trade. Students not only find it interesting, but it is necessary to understanding much of the political economy of trade policy. We have found it effective to begin with the Stolper-Samuelson theorem, and then contrast it with the results of the specific-factors model. We have taken special care in the text to consider the case of specific factors inasmuch as factors appear to be less than perfectly mobile in the short run. F. The material that examines the impact of relaxing several of the H-O assumptions should not be slighted. We think that it provides a good background for Chapter 9’s focus on empirical tests of the H-O model.

G. In Figure 15 on page 152, we have shown the price effect of the opening of the country to trade – a rise is PX/PY of 10 percent – as a shift upward of DLX (= MPPLX·PX) of 10 percent. Thus we are attributing the rise in PX/PY of 10 percent entirely to a 10 percent rise in PX. This is clearly a simplification; the actual PX/PY change of 10 percent would consist of a combination of a rise in PX and a fall in PY. To have PX shift up by, say, 6 percent and PY shift down by 4 percent could also accomplish the main point of this diagram – that the real wage falls for someone who consumes mostly the export good and rises for someone who consumes mostly the import good – but in a much more cumbersome way. You can certainly make the point by shifting the DLX curve upward and the DLY curve downward simultaneously, of course, as that is technically more accurate. V.

Answers to End-of-Chapter Questions and Problems

1. The physical definition of factor abundance is based on the relative physical amounts of the factors present in the country, e.g., the difference in the capital/labor ratios. The country whose K/L ratio is the largest is defined to be the capital-abundant country. The price definition is based on relative prices of the factors rather than on measurements of their presence in the country. It is hypothesized that the relatively-abundant factor in a country should be relatively cheaper compared to a second country. Thus, according to this definition, if the ratio of the price of capital to the price of labor is lower in one country (A) compared to a second country (B), country A is said to be the capital-abundant country. Under the assumptions of H-O, the two definitions should give the same result. However, if tastes differ between the two countries, then factor prices will not only reflect different supply conditions but also different demand conditions. In this instance the price definition and the physical definition could give conflicting conclusions about relative factor abundance. For example, if consumers in a physically capital-abundant country strongly prefer the capital-intensive product, this would bid up the price of the capital-intensive good and hence would bid up the price of capital. Therefore, other things equal, w/r would fall and could become lower than in the second country. Hence, the physically capital-abundant country could become labor abundant by the price definition. 2. According to the H-O theorem, countries should specialize in and export the product that uses relatively intensively the relatively-abundant factor. Therefore, Belgium should export capital-intensive goods to France because, by the physical definition, Belgium is the capitalabundant country. 3. The wages in the capital-abundant country should fall and the wages in the laborabundant country should rise with trade according to the factor price equalization theorem. Therefore, French wages should fall. 4. Assuming that the owners of capital are worried that the distribution of income will turn against them with trade, one concludes that the country in question must be a labor-abundant country. This follows from the Stolper-Samuelson theorem, which indicates that international trade will increase the real income of the owners of the abundant factor and lower the real

Chapter 08 - The Basis for Trade: Factor Endowments and the Heckscher-Ohlin Model

income of the owners of the scarce factor. 5. Assuming that the country in question is a small country, the opening of the country to international trade will force the monopolist to become a price taker, i.e., to sell the product in question at the prevailing international price or lose its domestic sales. This will cause the monopolist to reduce price and expand output. Even if the country is not a small country, there would be downward price pressure as imports come into the country. In either case, if the international price were below the firm’s shutdown point (minimum average variable cost), the firm would stop producing immediately and go out of business unless it was able to become competitive internationally (reduce its cost of production). 6. If demand conditions are different between the two countries and sufficiently oriented toward the product using relatively intensively the physically relatively-abundant factor in at least one country, the relative autarky prices will be just opposite to what H-O would predict. That is, the price of the capital-intensive good will be relatively higher in the physically capitalabundant country and the price of the labor-intensive good will be relatively higher in the physically labor-abundant country. Consequently, the opening of trade will lead to a pattern of trade just opposite to that predicted by H-O, i.e., the physically capital-abundant country will export the labor-intensive good and import the capital-intensive good. If such extreme differences in demand are possible, then the H-O paradigm can no longer predict the pattern of trade between two countries when using the physical definition of relative factor abundance. Note, however, that the trade pattern still conforms to Heckscher-Ohlin when using the price definition of relative factor abundance. 7. Assume that capital is a specific factor of production, i.e., that it cannot move from the production of one product to the production of the other. As trade opens in the capital-abundant country, the country will attempt to expand production of the capital-intensive good (and export it) and contract production of the labor-intensive good (and import it). Because capital cannot move, the change in production takes place by the movement of labor from labor-intensive production to capital-intensive production. This increases the demand for labor and hence the wage rate. Owners of capital in the contracting (labor-intensive) industry find themselves with excess capacity and a falling return to capital. In the capital-intensive industry, the productivity of capital and hence the real return to capital are rising. Although the wage rate is also rising, it is not rising as fast as the price of the export (K-intensive) good due to the declining marginal productivity of labor in the production of the K-intensive good. Consequently, workers who consume only the K-intensive good will find themselves worse off. Thus, those who unambiguously stand to benefit from trade are workers who consume only the cheaper laborintensive good and the owners of capital used in the expanding capital-intensive industry (whose real income is rising). Those who unambiguously stand to lose are workers who consume only the capital-intensive good and owners of capital used in the production of the labor-intensive product (whose real income is falling). 8. You should not be surprised if the composition of trade changed. Before the upheavals in Eastern Europe and the Soviet Union, the majority of trade of most of the Eastern European countries was with each other and with the Soviet Union through a managed and negotiated 8-2 © 2014 by McGraw-Hill Education.

framework. With the dissolution of the Soviet Union and the opening of trade with the West, prices began to reflect more accurately the true scarcity values of goods, and the Eastern European countries were also exposed more fully to a new set of potential trading partners. Hence, the relative factor endowments of the Eastern European countries vis-à-vis trading partners and the ability to respond to those endowments changed. Given the new relative scarcities, Heckscher-Ohlin analysis would tell us that new comparative advantages and hence a new pattern of exports and imports would emerge. For example, Hungary is most likely capital abundant relative to Romania but labor-abundant relative to Austria; a change in trading partners from Romania to Austria would clearly affect Hungary's trade pattern. 9. Given that the specific-factors PPF intercepts the good X axis at a point to the left of the point where the “normal” PPF intercepts the axis, that the economy is characterized by increasing costs, and that only labor is being transferred from industry Y to industry X in the movement from A’ to C’, the slope of the specific-factors PPF at C’ is necessarily steeper than the slope of the “normal” PPF at B’. Consequently, a change in relative prices that would lead to optimal production at B’ where [(PX/PY) = (MCX/MCY)] will be tangent to the specific-factors PPF at a point somewhere between C’ and A’. The presence of factor immobility increases the relative marginal cost of increasing production of good X and, hence, reduces the production response to the relative increase in PX. 10. This statement is correct because complete factor-price equalization can take place in the Heckscher-Ohlin framework only if product prices are the same in the two countries with trade. In the presence of transportation costs, the price of any good will differ between two countries by the amount of transportation costs. Hence, because product prices are not the same, factor-price equalization will not take place. 11. In this case, the apparent contradiction of the Heckscher-Ohlin model could be explained by factor-intensity reversal. In the United States, agricultural production utilizes considerable capital and, thus, many agricultural commodities such as rice are relatively capital-intensive. In India, however, agricultural production uses relatively much more labor than capital and, in all likelihood, is a labor-intensive product. Since there is considerable substitutability between capital and labor in the production of, for example, rice, it would not be surprising to find that rice is a labor-intensive product in a labor-abundant country such as India and capital-intensive in a capital-abundant country such as the United States. Consequently they both end up exporting the product because it is intensive in their respective abundant factors. 12. The specific-factors model makes it clear why, for example, if capital is immobile owners of capital in an import-competing product in a capital-abundant country would oppose the initiation of international trade. This is because owners of capital in a contracting industry unambiguously are worse off with trade. Improving the mobility of capital in this instance could enable the owners of capital in these declining industries to benefit from trade instead of finding themselves strictly worse off, as they would if their capital could not be easily adapted to production of the comparative advantage good. In graphical terms, improving factor mobility would move the factor-specific PPF (Figure 14) outwards towards the “normal” PPF. Such a change would lead to greater specialization, increased real income (a consumption-possibilities 8-2 © 2014 by McGraw-Hill Education.

III.

Purpose of Chapter

The main purpose of this chapter is to summarize various tests of the Heckscher-Ohlin theorem as a predictor of trade patterns among countries, in order to acquaint students not only with the applicability/non-applicability of Heckscher-Ohlin in practice but also with relevant testing techniques. In addition, we have included material on the growing income inequality in the United States and other countries so as to make students aware of the potential causal role of Heckscher-Ohlin trade in the phenomenon. As with the H-O theorem itself as the underlying basis of trade, there is also considerable controversy pertaining to the empirical importance of H-O trade in leading to the increased inequality.

have developed an appreciation of the difficulties of testing hypotheses in economics, as well as recognition that H-O has not been conclusively demonstrated to be empirically valid and that other factors besides trade may have played a role in the emergence of the greater inequality. IV.

Teaching Tips

A. The chapter begins with a discussion of a broader role for empirical work in international trade. Davis and Weinstein (Eastern Economic Journal, Fall 1996) suggest that empirical work can be a key to analyzing the assumptions associated with different theories. This is exactly what students need to be doing in this chapter. Through examining the various tests of the Heckscher-Ohlin theorem, the students will increase their understanding of the strict assumptions made in the model and can determine which assumptions are crucial. B. Very few undergraduates seem familiar with input-output analysis. If time permits, elaboration of that valuable analytical technique can be useful. C. The material in the first “In the Real World” box is not usually covered in textbook discussions of the Leontief paradox. Several of our referees found it interesting and worth including, and you might want to discuss it to some extent since it tends to buttress the conclusion about a “paradox.” D. Students always seem to have trouble understanding the Minhas test of factor-intensity reversals. You should explain this carefully, emphasizing how strong the assumption of “no factor-intensity reversals” really is. E. Because there are continuing tests of Heckscher-Ohlin appearing in the literature, we suggest that you supplement the “more recent tests” section of the chapter with later work as it comes out. This section of the text can become outdated rather quickly. A useful book is Robert E. Baldwin, The Development and Testing of Heckscher-Ohlin Trade Models: A Review (Cambridge, MA: The MIT Press, 2008). F. The issue of inequality is one that excites interest, perhaps because it is one that students seem not to have thought about in any systematic way. In addition, our experience is that many of our students come from families well above the median income level and don’t really realize it, so discussion of inequality is eye-opening to them. We suggest that you have students find data on inequality (say, for the United States, from the Census Bureau’s Current Population Reports or Statistical Abstract of the United States, or, for many other countries, from the World Bank’s World Development Indicators) and present them to the class. Further, a mini-debate on the role of trade in inequality can be very worthwhile, if time permits. G. The material in the fourth “In the Real World” box provides a nice opportunity to examine the (politically-sensitive) issue of outsourcing with students.

Answers to End-of-Chapter Questions and Problems

1. The Leontief paradox was the finding by Wassily Leontief in 1953 that the capital/labor ratio utilized in U.S. import-substitute industries when weighted by import importance was greater than the capital/labor ratio utilized in U.S. export industries when weighted by export importance. This finding suggested that the United States was importing relatively capitalintensive goods on average and was exporting relatively labor-intensive goods on average. This result was contrary to the trade pattern expected from the Heckscher-Ohlin theorem, since the United States was generally thought to be a relatively capital-abundant country. 2. This is a judgmental question because several explanations involving demand reversal, factor-intensity reversals, the U.S. tariff structure, labor skills, and natural resources have been offered to account for the paradox. In general, however, the major defect seems to be that the Leontief test utilized a two-factor model, that is, it failed to differentiate labor according to various skill categories and to allow for the role of natural resources. Subsequent studies have suggested that U.S. exports might be relatively “skilled labor-intensive” or “human capitalintensive,” and that imports may be relatively intensive in natural resources as well as in relatively unskilled labor. 3. With factor-intensity reversal, suppose U.S. exports that would be produced abroad by relatively capital-intensive techniques are produced with relatively labor-intensive techniques in the United States. In addition, suppose that U.S. imports that are relatively labor-intensive in production in the supplying countries are produced in relatively capital-intensive fashion in the United States. If the United States is relatively capital-abundant, it is thus importing goods that would be classified as relatively capital-intensive in the United States and exporting goods that would be classified as being produced relatively labor-intensively in the United States. Because Leontief’s test utilized the U.S. input-output table and U.S. techniques, this yields the paradox. In the presence of demand reversal, the relative price of the good intensive in the abundant factor is higher (the relative price of the good intensive in the scarce factor is lower) compared to the relative international price. Consequently, the country will export the good that is intensive in the scarce factor and import the good that is intensive in the abundant factor. A capital- abundant country (in this case the United States) will thus be importing the capitalintensive good and exporting the labor-intensive good (using the price definition of relative factor abundance), contrary to the H-O prediction. This appeared to be the case for the United States in the initial Leontief study (hence the Leontief paradox). 4. The answers to this question will vary with student experiences. When traveling in developed countries, the students will most likely not have observed demand patterns to vary much across countries, with an emphasis on goods that are relatively “high tech” in nature or relatively capital-intensive in production (such as DVD players, automobiles, cell phones, personal computers). In developing countries, some of these same items will be observed in urban areas, but food and simple clothing items (more labor-intensive goods) will be more noticeable outside the urban centers. These observations may suggest to the students that some tendency toward demand reversal exists, but travelers are not usually exposed to the capital goods and intermediate goods imports of developing countries.

Chapter 09 - Empirical Tests of the Factor Endowments Approach

5. These barriers may reflect the desire to engage in import substitution, with the laborabundant low-income developing countries in particular feeling threatened by perceived higher quality labor-intensive products from newly-industrializing countries and developed countries. There is no necessary contradiction here with Heckscher-Ohlin if the potential imports reflect product differentiation and intra-industry trade (to be discussed in Chapter 10). Also, in light of the Stolper-Samuelson theorem, the owners of capital (the relatively-scarce factor in developing countries) may be seeking protection since freer trade will reduce the return to capital. These capital owners may also have disproportionately heavy influence in the policy-making process. 6. This answer requires some judgment on the part of the student as to the relative success of the Heckscher-Ohlin tests discussed in the chapter. Certainly the two-factor Heckscher-Ohlin model is a good candidate for being discarded in empirical work, but the multifactor approach has promise. In view of the findings of Bowen, Leamer, and Sveikauskas, and more recently Daniel Trefler and others, however, the search for other theories of trade can be useful for supplementing Heckscher-Ohlin with such influences as demand patterns, technological change, and changing comparative advantage. (These kinds of influences are discussed in Chapter 10.) Hence, perhaps a multifactor Heckscher-Ohlin approach and a “newer theories” approach should both be pursued, and an “either-or” question may not be appropriate. 7. A sample answer: The rise in income inequality in the last 10-25 years has occurred at the same time that the U.S. economy has experienced a substantial rise in its imports/GDP ratio. Because many of these imports have come from relatively labor-abundant developing countries and are relatively unskilled labor-intensive goods that were manufactured or assembled in these countries, there has been relatively less demand for domestic unskilled labor and hence downward pressure à la Stolper-Samuelson on the wages of that part of the U.S. labor force. At the same time, the United States has been exporting high-tech products that require relatively skilled labor, and thus there has been relatively increased demand for the services of this kind of labor with a consequent rise in the relative return of skilled labor. Therefore, from both the export and the import side, there has been rising inequality within the U.S. labor force. While technological change, the weakening of labor unions, and other such factors have been responsible for some of the relative factor price rise of skilled labor compared to unskilled labor, these phenomena also can be traced back to trade because the threat of global competition has induced the technological change, reduced labor union strength, and so forth. The empirical work of Adrian Wood in particular lends credence to the view that trade has been the principal mechanism that has generated the rising inequality.

Chapter 09 - Empirical Tests of the Factor Endowments Approach

8. A sample answer: While it is clear that increased income inequality and increased U.S. openness to imports have occurred at the same time, trade is but one of several factors in today’s rapidlychanging world that have led to the greater inequality. The nature of technological change seems to be the most important factor, because the increased demand for skilled labor to work with the new technology has led to a rise in the skilled labor/unskilled labor ratio in all industries, not just in traded goods industries. Further, there is little evidence that the relative prices of unskilled labor-intensive goods to skilled labor-intensive goods have fallen, which is necessary for the Stolper-Samuelson mechanism to occur. Other factors have also played a role in the increased inequality, such as a decline in the importance of unions and a fall in the real minimum wage, and these factors are likely due to the political climate and/or to the changing structure of the American economy from manufacturing to services, rather than to trade itself.

Essay Questions

1. How can it be said that the factor-content approach “reveals” a country’s factor abundance? What assumptions seem crucial for making this inference? Explain. 2. The text notes that, if demand reversal were the cause of the Leontief paradox, then labor would be relatively cheap in the United States. Explain the reasoning behind this statement. 3. If economists wish to determine relative factor abundance across countries, why don’t they simply calculate w/r ratios across countries and then compare these ratios? 4. The European Union has heavily protected its farm sector through import duties; in addition, the Union subsidizes its exports of agricultural products. If “cropland” is regarded as a factor of production and is included in the Leontief statistic (along with, say, labor), how would the presence of these agricultural policies affect the results of such tests? Explain. 5. If factor-intensity reversals were indeed prevalent in the real world, how might this fact be used to explain the Leontief paradox? If this explained the paradox, would it suggest that any given U.S. trading partner stood a better chance of conforming to Heckscher-Ohlin than did the United States (i.e., will a factor intensity reversal yield “incorrect” H-O results for both countries)? Why or why not? 6. Why can it be suggested that the fact that the ratio of skilled labor/unskilled labor has risen in almost all U.S. industries in recent years (and not just in traded goods industries) lends support to the view that increased inequality in the United States is not primarily due to increased Heckscher-Ohlin-type trade? How might you counter this suggestion?

7. Explain the economic process by which it can be hypothesized that increased participation in international trade by the United States in the last several decades has led to increased income/wage inequality in the United States. Then indicate why some economists doubt that the increased trade has been such an important factor, and explain other influences that economists think might have been important. Finally, if you were to pass judgment on this matter, what would be your view of the source(s) of the increased inequality and how would you defend your view? 8.

(a) Explain how the Heckscher-Ohlin theorem is obtained, using either the “physical” definition or the “price” (or “economic”) definition of relative factor abundance. (b) Illustrate and explain the phenomenon of a “factor intensity reversal.” If two countries are trading in a situation where such a reversal has occurred, can the Stolper-Samuelson theorem still be valid for both of the countries?

Chapter 10 - Post Heckscher-Ohlin Theories of Trade and Intra-Industry Trade

III.

Purpose of Chapter

The purpose of this chapter is to present some newer theories of trade that have emerged in the literature because of the failure of the Heckscher-Ohlin model to explain empirically important parts of world trade, specifically the growing trade in manufactured goods. In addition, because intra-industry trade emerges in some of these newer theories and because such trade is important in the real world, the last part of the chapter briefly surveys possible causes of this phenomenon. IV.

Teaching Tips

A. The chapter begins with an examination of the empirical evidence related to U.S. imports from Mexico. The initial thought is often that fruits and vegetables or clothing will top the list. In reality, electrical machinery and equipment ranks first and vehicles rank second. These same items top the list of U.S. exports to Mexico. This is certainly not the predicted trade patterns of the traditional models and provides a nice opening to discuss intra-industry trade and several elements of the newer trade theories that emphasize trade in manufactures. B. With respect to the product cycle theory (PCT), Vernon suggested in his original article that the PCT could help to explain the Leontief paradox because when the product was being imported into the United States in the standardized product stage it was more capital-intensive than when it was first introduced and exported by the United States. We have not utilized this point in our discussion because to us it seems incorrect. The relevant comparison would be between the capital intensity of imports and the capital intensity of exports at any given point in time. Thus the older (imported) product’s intensity should be compared with the intensity of the successive newer products. C. Another useful graph to employ in the presentation of Linder is one found in John Adams, International Economics: A Self-Teaching Introduction to the Basic Concepts, 2nd ed. (St. Martin’s Press, 1979), p. 95. Per capita incomes of a home country (say country A) and its trading partners are arrayed on the horizontal axis; the vertical axis measures the intensity of trade (average propensity to import) of A with the various trading partners. The conceptual result from Linder is a hill-shaped figure peaking at A’s per capita income, since the intensity of trade with any given partner is less the farther away that country’s per capita income is from A’s per capita income. D. A main point of the economies-of-scale discussion (introduced on page 190 and expanded in Appendix A) is that two countries identical in all respects can still receive gains from trade (although the precise pattern of trade may be a priori indeterminate). A further point to emphasize is the trade patterns become unpredictable from a Heckscher-Ohlin standpoint in the presence of economies of scale. E. The Krugman model (introduced on page 190 and expanded in Appendix B) may be difficult for the students. It is advisable to emphasize the general scenario while examining the details: that trade permits a larger market, which in turn permits internal economies of scale to

be realized, which in turn permits lower consumer prices; in addition, a greater variety of differentiated goods is produced. The end result is that, again, identical countries can experience gains from trade, something not possible in Heckscher-Ohlin. V.

Answers to End-of-Chapter Questions and Problems

1. The length of the imitation lag would be influenced by barriers to obtaining information regarding the production process, the existence of patents, the length of time needed to learn the production process even after the information is obtained, or the extent to which multinational companies exist in the industry, for example. The demand lag would be influenced by the degree to which tastes are similar in the countries, the ease of communication, the amount of interaction between foreign consumers and the home country (e.g., via travel), product loyalty, and so forth. 2. Some examples would be automobiles, tractors, clothing, television sets, textile machinery, personal computers, and some sporting goods. 3. The Linder theory would suggest somewhat pessimistic prospects in that the per capita income levels and thus the overlapping demands differ widely between the two sets of countries. Indeed, Linder would suggest that the developing countries would trade most intensely with each other, which is not the case in practice. However, many labor-intensive goods sold to developed countries by developing countries (textiles, clothing, shoes) do have some overlap in demand, although the varieties exported may be of higher quality than those sold on developing countries’ home markets. Electronic goods that are assembled in developing countries for export to developed countries would not fit Linder well, since relatively small markets exist for those goods within the developing countries and the goods would not be classified as being “representative” of consumer demand in the developing countries. The Linder theory does not handle the phenomenon of production specifically for export very well. Also, of course, the theory does not embrace primary products (nor was it intended to). 4. The precise countries of export and import of any particular good may not be determinate a priori. The trade pattern may simply depend on which country first establishes a foothold in the market. 5. Before trade begins, many monopolistically-competitive firms producing differentiated goods are in equilibrium with zero profit. When the possibility of trade with other countries begins, export sales of firms increase production because the size of the market has increased and profit prospects have been enhanced. Firms experience reductions in unit costs as they expand, and new varieties of the differentiated goods also appear in the country because home consumers now have foreign varieties available to them. In the trading equilibrium, consumer prices have fallen, more varieties are available, and intra-industry trade in differentiated products is occurring. Because of the greater product variety and the increase in real income due to reduced product prices, consumers in all participating countries are better off than in autarky. 6. Greater choice for consumers may bring greater utility in and of itself. New varieties may initially provide more utility per dollar at the margin and lead to enhanced welfare as new 10-2 © 2014 by McGraw-Hill Education.

equilibrium positions are sought by consumers. Disadvantages associated with greater product variety would be increased advertising costs of firms (which use resources) and the costs to consumers of obtaining information on the characteristics of the differentiated products. There may also be a greater time cost because of the more complicated decision-making process. 7. No. As pointed out in the text, geographical location and transport costs can lead to intraindustry trade in identical products. In addition, the degree of disaggregation in the product classification system may not be detailed enough to capture what are truly different products (e.g., different chemical compounds, special-use machinery). 8. It is a useful distinction if one grants that many differentiated varieties of a product are indeed the same general “product” (i.e., the cross elasticities of demand between the varieties are high). If such is granted, the analyst is forced to look beyond traditional trade theory when examining causative factors for trade patterns. If such is not granted, however, it becomes difficult to explain the U.S. export of Budweiser and import of Corona by relying only on different factor endowments and intensities. 9. The emergence of counterfeit goods suggests that the time lag between initial U.S. production and subsequent production abroad is being shortened. The product cycle is speeding up, and the displacement of U.S. exports in the “maturing product stage” is occurring more rapidly. In addition, unlike the situation in the traditional product cycle, some of the production abroad is not taking place in U.S.-owned facilities. Because the erosion of U.S. firms’ profits is occurring more quickly, there is less stimulus for U.S. R&D spending on new products to be undertaken than there would be if patents or proprietary knowledge could effectively protect against the counterfeit goods. Hence, while any given product cycle may be more rapid today, there may also be fewer future cycles. 150922560. In the “reciprocal dumping” model, each country’s consumers benefit from a flow of imports of the good coming into the country at a lower price than was initially being charged by the domestic monopolist. The lower import price and consequent increased consumption bring a welfare gain, as does the reduction of price by the monopolist in each country in order to meet the new foreign competition. However, there are welfare losses in the sense that resource costs are now being incurred to move the good (in both directions) between the countries, and these resources are being diverted from other welfare-creating activities. If the welfare gains offset the transport cost losses, the trade has been beneficial on balance. 11. The initial shift of athletic shoe production from the United States to South Korea is consistent with the product cycle theory’s suggestion of a shift, as the product becomes more standardized, to a new location with lower labor costs. However, it does not strictly fit the PCT’s suggestion of an initial shift to another developed country comprised of high-income consumers. The next shift in production from Korea to Indonesia and China, as wages rose in Korea, is also consistent with the PCT’s general emphasis on the role of lower wages in determining production location in the “standardized product stage” when the good is “older,” mass-produced, and sold worldwide.

standards than South Korea, which has been rapidly moving toward “developed country” status. Obviously, Heckscher-Ohlin could also be of use in explaining the athletic shoe production shifts. In the H-O context, South Korea was labor-abundant relative to the United States and shoe production is a relatively labor-intensive process. However, the subsequent rise in Korean wages indicated a change toward less labor abundance in Korea. This gave an incentive for shoe production to shift toward Indonesia and China, which are relatively more labor-abundant than South Korea. 12.

Chapter 11 - Economic Growth and International Trade

IV.

Teaching Tips

A. The chapter begins with an examination of the huge increase in China’s international trade and its impact on economic growth. The interesting aspect is that the growth of Chinese trade is also having an impact on South Korea, Taiwan, and even Japan. This is an example of trade serving as a source of growth for an entire region. B. In discussing the production and consumption effects of growth on international trade, we distinguish between the normal protrade and antitrade effects and the more extreme ultraprotrade and ultra-antitrade effects. However, one can focus on just the pro and anti effects generally and ignore the further breakdown. What is important for the student to realize is that growth influences trade both from the supply side and from the demand side. C. We chose to analyze the influence of technological change on growth only from the standpoint of factor-neutral, commodity-specific change. If you have a special interest in growth and trade, you might find it useful to note that economywide technological change can be factorspecific as well. In this instance, the impact on the economy conceptually is analogous to that of a factor-neutral change plus growth in availability of the affected factor, and can be analyzed as such. D. Contrasting the impact of factor growth with that of changes in technology on income growth is effectively done with the PPF. At the end of this section, the student should be left with a clear impression of the different manner in which commodity-based technological change affects the PPF compared to that of growth in a single factor. E. The section of the chapter that presents the Rybczynski theorem and examines the impact of growth on welfare in the small-country case is clearly tougher material and may require more attention in class. F. Given the problems associated with reaching welfare conclusions in a dynamic setting, it is useful to introduce the student to the use of a proxy such as per capita income to draw a tentative conclusion. Although it is more rigorous, we have found the explanation of the decline in per capita income associated with growth in labor alone to be effective (Concept Box 1). G. Students find it surprising that only ultra-antitrade-biased growth shifts the offer curve to the left (Concept Box 2). This gives you an opportunity to distinguish relative effects on trade from absolute effects on trade. H. Although there has been a tendency to pay less attention to the terms-of-trade issue in recent years, this is still an important concern for many developing countries. The possibility of immiserizing growth developed by Jagdish Bhagwati is a very effective way to integrate growth and relative price effects, and the immiserizing growth concept seems of definite interest to students. There is little doubt that changes in developing countries’ terms of trade that are associated with world growth are still of concern to policymakers in developing countries. V.

Chapter 11 - Economic Growth and International Trade

1. The growth in only one factor leads, according to the Rybczynski theorem, to the expansion of output in the good using intensively the growing factor and a contraction in output of the good using intensively the non-growing factor. If the growing factor is the abundant factor, then the result is an expansion in production of the export good and a decline in production of the import-competing good (an ultra-protrade production effect) because some of the scarce factor must be shifted away from import-competing production to export production in order to work with the new units of the abundant factor. If the growing factor is the scarce factor, then there will be an expansion in output of the import-competing good and a contraction in output of the export good (an ultra-antitrade production effect) since some of the abundant factor is shifted to work with the new units of the scarce factor. 2. Yes. Because growth in the abundant factor will result in an ultra-protrade production effect, the trading triangle will increase in size unless there is a sufficiently large ultra-antitrade consumption effect. Only if the absolute level of desired consumption of the import good declines sufficiently with growth will the trading triangle get smaller. 3. An inferior good is one whose consumption declines with growth in income. An absolute decline in desired consumption of the export good and an increase in desired levels of consumption of the import good characterizes an ultra-protrade consumption effect of growth. 4. The trading triangle could expand as in the small-country case as long as the Rybczynski production effect (expansion in production of the import-competing good and contraction of the export good) is more than offset by a sufficiently large ultra-protrade consumption effect (although this of course implies that the export good is an inferior good). In the large-country case it is also possible for an expansion of the trading triangle to take place with other consumption effects, due to the decline in world price of the import good as its demand declines in the country under consideration. It is certainly possible for the increased purchases of the import good due to the subsequent relative decline in the price of that good to more than offset the initial decline in the trading triangle due to the growth of the scarce factor. 5. This would be the case when the country in question is a large country in terms of the good in question. In this instance the bumper crop would lead to a fall in the relative world price of the export good. If this decline in relative price were sufficiently great, the country could well find itself worse off after the bumper crop. This is a case of immiserizing growth. 6. If constant or decreasing returns to scale characterize production of all commodities, then increasing only one of the inputs by a given percentage, e.g., 10 percent, will result in output rising by less than 10 percent. If the input in question is labor (population), then a 10 percent increase in labor will lead to a less than 10 percent increase in income, and per capita income [income/labor (population)] will decline since the numerator is growing less rapidly than the denominator (see Concept Box 1). If there were increasing returns to scale at least partly because of increasing marginal productivity of labor, then clearly per capita income could rise with an increase in the labor force. However, if the normal diminishing marginal productivity of labor exists, even with increasing returns to scale, per capita income will still fall with growth in the labor force because other factors of production are being held constant.

Chapter 11 - Economic Growth and International Trade

7. The sluggish growth in the Japanese economy in the early 1990s meant that Japan’s production-possibilities frontier (and hence its consumption-possibilities frontier) was not shifting outward very rapidly. On the other hand, Japan’s major trading partners in Asia (e.g., China) were growing rapidly, and the United States (Japan’s largest overall trading partner) recovered relatively quickly from its 1990-91 recession. These trading partners also were growing in “protrade” fashion. Hence, for these trading partners, PPFs and CPFs on average shifted out more rapidly than for Japan. The partners were offering relatively more exports and demanding relatively more imports in their trade on the world market and with Japan, and this tended, other things equal, to cause deterioration in their terms of trade with Japan. With TOT deterioration for the partners, Japan’s terms of trade improved. 8. The PPF of the unified Germany would lie outside that of the former Federal Republic of Germany. In addition, since East Germany was relatively more labor-abundant than West Germany, the new unified PPF will not have shifted out proportionally, but will have shifted relatively more on the labor-intensive good axis. If international prices have remained unchanged, output of the labor-intensive good will clearly increase. However, output of the capital-intensive good could have increased, stayed the same or decreased depending on the relative increase in capital coming from East Germany. If West Germany was a capital-abundant country, according to Heckscher-Ohlin, it should have been exporting the capital-intensive good. Assuming that West Germany was initially exporting capital-intensive goods, the above production effect will fall into either the category of ultra-antitrade (when the production of the capital-intensive export good actually falls) or antitrade (when the growth in production of the labor-intensive import-competing good is greater than that of the export good). 9.

Because the innovation was restricted to manufactured goods, the intercept of the new PPF on the manufactured goods axis is farther out than on the original PPF. There is no change in the intercept on the services axis since no change in production conditions have occurred there. The change in production conditions will result in an expansion of output of manufactures and a contraction of services at constant international prices. Because this country was initially exporting manufactures, the above changes would produce an ultra-protrade production effect. 10.

Volume of trade-2010: 28 units of exports of good X; 14 units of imports of good Y Volume of trade-2015: 30 units of exports of good X; 15 units of imports of good Y (b) 2005-2010: There is a protrade production effect because although production of both goods increased, production of the export good (X) increased by 20 percent whereas the growth of production of the import good (Y) was only 10 percent. 2010-2015: There is an antitrade production effect because, although production of both goods increased, production of the import good (Y) increased by 30.30 percent whereas the growth of production of the export good (X) was only 16.67 percent. (c) 2005-2010: Since the growth in consumption of the export good (15 percent) is slightly greater than the growth in consumption of the import good (14.3 percent), the consumption effect is slightly antitrade. 2010-2015: Since the growth in consumption of the import good (26.25 percent) is greater than the growth in consumption of the export good (19.57 percent), the consumption effect is protrade. (d) 2005-2010: The overall effect is protrade. This is evident since the volume of trade at the constant terms of trade grew by 40 percent, while the growth in output in this twogood economy was between 10 percent (the growth rate of production of good Y) and 20 percent (the growth rate of production of good X). 2010-2015: The overall effect is antitrade. This is evident because the volume of trade at the constant terms of trade grew by 7.14 percent, while the growth in output was between 16.67 percent (in the X industry) and 30.30 percent (in the Y industry. 11. Even if small developing countries are truly “small” in the sense that they cannot by their own actions influence their own terms of trade, they can still experience a terms-of-trade decline because of developments in their trading partner countries (i.e., the partners’ offer curves toward the developing countries shift toward less willingness to trade). If demand shifts away from the developing countries’ products over time because of taste changes or because of the rise of substitutes or for other reasons, the developing countries’ terms of trade will deteriorate. Likewise, if supply developments in trading partners or in world markets in general raise the prices of goods imported by the small developing countries, the terms of trade will decline. Another possibility is the case where a physically small developing country may in fact be a sufficiently important supplier of some individual primary commodity so that expansion in the production of this particular commodity leads to adverse terms-of-trade movements (i.e., the country is actually not economically “small” in this commodity).

Essay Questions

1. In recent decades, trade has been growing faster than income for many countries. What combination of trade effects is sufficient for this to come about? Is this behavior consistent with the Rybczynski theorem? Under what circumstances? 2. Why is it difficult to analyze the welfare implications of growth in the neoclassical model? What proxy is often used to reach a conclusion about the effects of growth? What leads to the conclusion that, if welfare is to improve with growth in the labor force, there must be accompanying growth in the capital stock and/or improvements in labor productivity? 3. Is it possible that growth in the scarce factor can actually lead to expanded trade in the small-country case? Under what circumstances? 4. Developing countries often claim that growth and trade have left them no better off or perhaps worse off. How might you explain this result theoretically? Could this result obtain if the countries tended to be relatively small? Why or why not? 5. It is likely that a protrade production growth effect will lead to an expansion of trade since the presence of inferior goods is relatively rare. Explain. 6.

Chapter 12 - International Factor Movements

III.

Purpose of Chapter

In the theoretical analysis to this point it has been assumed that factors are immobile between countries. Because this is clearly not the case, the purpose of this chapter is to examine the reasons for and the trade and income implications of movements of capital and labor between countries. IV.

Teaching Tips

A. With the current attention being paid to foreign investment and migrant workers, students should find the issues covered in this chapter contemporary and interesting. The discussion of the impact of foreign direct investment in China may be of particular interest. The Chinese case is controversial in the United States and many other countries that trade with China, and it serves as a very intriguing case study for this class. We want students to see the real-world application of these issues before they move into the graphical analysis of capital and labor movements. B. It is important to make certain that the students understand the capital market equilibrium concept that is developed early in the chapter and presented graphically in Figure 1. Once the analytics have been grasped, then summarizing the overall costs and benefits of foreign investment logically follows. C. Note that the labor market equilibrium paradigm in Figure 2 (page 250), which is analogous to the capital market paradigm developed earlier in Figure 1, is expanded in Figure 3 (page 251) to examine the implications of labor movements from a labor surplus country with an institutionally-determined wage (developing country) to a country where labor markets are in fact clearing. Although this is a more involved case, it allows one to demonstrate how the impact of factor movements is altered in the presence of factor price distortions. D. In teaching this chapter, it is important that class time be devoted to presenting the analytics of the chapter and any new information on current or “hot button” issues. Much of the descriptive material can be left to the students to read on their own. V.

Answers to End-of-Chapter Questions and Problems

1. At the end of December 2010, the direct investment position of the United States was a positive $1,565.4 billion, as foreign direct investment in the United States was $2,342.8 billion and U.S. direct investment abroad was $3,908.2 billion. Countries in Europe (especially) were the major recipients of U.S. investment with Latin America and Asia/Pacific a distant second and third. By destination, the Netherlands was the largest recipient, followed by the United Kingdom, Canada, Luxembourg, Bermuda, Ireland, Switzerland, and Australia. The investment tends to be concentrated in finance (except depository institutions) and insurance, manufacturing, and (with considerably less investment) wholesale trade, mining, and information. The five largest investor countries in the United States were the United Kingdom, Japan, the Netherlands, Germany, and Canada. Foreign investment in the United States is concentrated in manufacturing (heavily), wholesale trade, and finance (except depository institutions) and insurance.

Chapter 12 - International Factor Movements

2. In 2011, three of the top ten industrial corporations by revenue were U.S. firms, and three of the ten largest banks were U.S. banks. Three of the largest corporations were Chinese, two were Japanese, and there was one each from the Netherlands and the United Kingdom. In 2011, besides the U.S. banks, three of the top ten banks were from the United Kingdom, two were French, one was German, and one was Chinese. 3. Foreign direct investment takes place to earn a higher rate of return. This can result from specific market conditions abroad, from the access to foreign raw material sources, from the attempt to avoid tariffs, quotas, or nontariff barriers by producing abroad, or from taking advantage of cheaper foreign labor costs. 4. Assuming that capital is the scarce factor, foreign investment would lead to expansion of the capital-intensive import-competing good and contraction of the labor-intensive export good. This would be an ultra-antitrade production effect that would tend to reduce trade unless it was offset by a sufficiently strong ultra-protrade consumption effect accompanying growth (which requires that the import bundle is “inferior”). 5. The capital stock in the capital-abundant country would be larger and the capital stock in the capital-scarce country would be smaller. Consequently, output in the capital-abundant country would be larger, output in the capital-scarce country would be smaller, and their combined output would be smaller if capital controls were in place that kept the productivity of capital from equalizing. 6. Assuming that the developing country is a labor-abundant country and that the United States is the capital-abundant country, the movement of unskilled labor should tend to have an ultra-antitrade production effect in both countries. Inasmuch as skilled labor is more properly treated as a form of human capital, then the movement of skilled labor from the developing country to the United States would have an ultra-protrade production effect in both countries. 7. Voters would see the immigration of these skilled workers as increasing the availability of the goods or services which they produce and perhaps lowering the price. Skilled workers see the immigrants as potentially lowering their wage and real income. Congress should weigh the aforementioned costs and benefits of such migration flows and enact legislation consistent with the expected net welfare impact on the country. 8. If both factors of production and goods are free to move, it is difficult to predict the ultimate pattern of production and trade because factor movements substitute for goods movements. The ultimate pattern of trade will depend upon the degree to which factors move to equalize the returns to factors or goods are traded to accomplish the same end (through the factor-price equalization process). 9. With high Mexican tariffs in place, potential U.S. exporters (presumably of capitalintensive goods) found it difficult to compete price-wise with similar Mexican products. As Mexico has welcomed foreign investment in recent years, capital flows substituted for U.S. exports that had been kept out by the high tariffs. As trade restrictions are reduced under NAFTA, U.S. capital-intensive exports will become competitive in Mexico, reducing the need to

Chapter 12 - International Factor Movements

invest in Mexico in order to sell in Mexican markets. Thus, the expected trade adjustments that should occur under NAFTA could actually work to reduce U.S. investment in Mexico. 10. Many U.S. citizens have expressed concern over U.S. immigration policy because of their belief that large numbers of current migrants are contributing both to the presence of low wages and to the increased cost of public expenditures, particularly for social programs and education. The fact that the education/skill levels of immigrants appear to be declining contributes to this concern. To the extent that these workers are, however, taking on jobs that U.S. citizens do not wish to and are, in fact, providing unskilled labor at wages lower than most U.S. labor would accept means that U.S. consumers are able to purchase these goods and services at a lower price than would be the case in the absence of this immigration. This is particularly true with respect to many food products that utilize migrant labor during planting and harvesting as well as other services that utilize unskilled labor. To the extent that this is true, reducing migration flows will lead to higher prices of some goods and reduced real income of people for whom those products are important parts of their consumption bundle.

Sample Exam Questions

A.

Essay Questions

1. Explain the underlying basis for foreign direct investment, and discuss several factors that may contribute to it. What factors have likely contributed to the current U.S. net direct investment position? 2. Direct investment inflows by foreigners into the United States have been sizable in recent years. How might this net inward movement of capital affect the level and pattern of U.S. trade according to the Heckscher-Ohlin model? The level of world output? 3. Because real investment by foreigners expands a country’s capital stock and hence presumably its output and income, why should any country consider restricting foreign investment? 4. The recent immigration of labor into the United States from Mexico has led to increased calls for new restrictions on this movement of labor (including greater enforcement of existing restrictions). What would be the costs and benefits to the United States of such restrictions? 5. Many industrialized countries such as the United States attempt to seriously restrict immigration of production workers, but are more open to immigrants who are highly-skilled. Why might this be the case? Why is this a problem for developing countries and how might they deal with the problem? 6. The impact of labor migration on patterns of international trade depends on the characteristics of the labor migrants. In which cases might migration expand trade? World income? In which cases might it reduce trade and world income?

Chapter 13 - The Instruments of Trade Policy

III.

Purpose of Chapter

The purpose of the chapter is to introduce the wide variety of trade-distorting instruments that exist in practice, as well as to acquaint students with particular policy concepts such as most-favored-nation treatment (normal trade relations) and the effective rate of protection. Once the instruments are understood, the stage is set for the discussion of their market and welfare implications in Chapter 14. IV.

Teaching Tips

A. In this chapter we have refrained from saying much about welfare – reserving that discussion for Chapter 14. The chapter begins with four examples of the instruments of trade policy being used by industrialized nations. Hopefully, the students will be motivated to use this chapter to classify these instruments and to gain an understanding of how the instruments are used. If you don’t like our division of instruments and welfare effects, feel free to combine the two chapters if that helps. B. In the discussion of GSP, it is useful to spend more time than we do in the text on the fact that there are ceilings to the quantities of imports that can come into the United States (although not for the “least developed” countries) and that the range of goods permitted is rather limited. Also, the “graduation” issue seems of some interest to students. C. For some reason, students have trouble grasping the ERP concept. It helps to make clear at the outset that the discussion concerns protection for a home import-substitute industry and that the final good’s tariff, because of the reduction in overall supply on the home market, raises the price that domestic producers receive to the world price plus the tariff. D. In the discussion of ERP, it is important to note that the tariffs on inputs raise the domestic price of identical home-produced inputs, too. Some texts imply that the inputs used in the ERP formula are only the specific units of the inputs that are imported and not produced at home, but that is not a necessary condition – the inputs can be produced at home under a situation where imports of the goods also exist. E. Pertaining to the discussion of VAT, some students who have traveled in Europe may have received VAT rebates. Reference to this can help the class understand the discussion. F. The Scott Bradford study summarized on pages 284-85 provides a look at the impact of protection in a more practical, real manner than is perhaps provided simply by observing actual tariff rates. V.

Answers to End-of-Chapter Questions and Problems

1. Preferential duties discriminate by trade partner in the importation of any given product, while the objective of MFN treatment (or normal trade relations) is to be nondiscriminatory. Because, under MFN, any tariff reduction to one partner is extended to all others with whom MFN agreements exist, the reduction does not benefit only one or a few partners (as it would 13-2 © 2014 by McGraw-Hill Education.

under preferential duties) to the exclusion of other trading partners. 2. Those industries and residents of a country who can benefit from protection are continuously seeking mechanisms by which their well-being can be enhanced. As tariffs have been reduced through international negotiations, these economic agents have sought to preserve their protected status by pushing for legislation and regulations regarding other barriers (NTBs) not covered by the negotiations. 3. Value added under free trade is $1,000 - ($300 + $500) = $200. In the small country case, the price of good F becomes $1,000(1 + 0.20) = $1,200. The price of input A becomes $300(1 + 0.20) = $360, and the price of input B becomes $500(1 + 0.30) = $650. Value added under protection is thus $1,200 - ($360 + $650) = $190. The ERP is therefore ($190 - $200)/$200 = minus 5 percent. The meaning of this ERP result is that the returns to the factors of production in the F industry as a whole have actually been reduced by 5 percent by the tariff structure, and there would be an incentive for the factors to leave this industry. 4. Probably not. For nominal tariffs, the problem of under- (over-) representation of high(low-) tariff goods prevents precise measurement by a weighted-average tariff, and an unweighted-average tariff will obviously only be approximate. The use of world weights is not satisfactory conceptually, as it does not embody the country’s actual trade pattern. For effective tariffs, problems regarding the reliability of the relation of inputs to output occur (especially if the input coefficients are not fixed), in addition to the nominal tariff calculation problems. With respect to NTBs, these barriers would need to be identified clearly and then converted to tariff equivalents. This would require estimation of price and quantity impacts (that is, of demand and supply elasticities). Taking the various tariff and NTB problems together, the best efforts to calculate an average level of protection will only produce approximations. In addition, all tariff and nontariff barrier calculations are made more difficult if the importing country is a “large” country, for then an estimate must be made of the levels of world prices of the various imports if there were no import restrictions in place. Finally, if the various errors and omissions are roughly of the same relative magnitude over time, more certainty can be attached to the trends shown by the protection indexes than to the calculated levels of protection themselves. 5. The ERPs for the country’s final goods industries will increase, meaning that these production processes are protected to an even greater extent than previously. Trading partners sending final goods to the country would regard this action as a move in the direction of less willingness to trade rather than in the direction of greater willingness to trade. 6.

(a) The unweighted-average nominal tariff rate is equal to: 0.10 + 0.05 + 0 + 0.30 + 0.02 + 0.025 + 0.15 + ($0.50/$4.00) + 0.40 + ($2.50/$10.00) 10 = 1.42/10 = 0.142 or 14.2 percent

(b) The weighted-average nominal tariff rate is: (0.10)($400) + (0.05)($600) + (0)($500) + (0.30)($300) + (0.02)($200) + (0.025)($400) + (0.15)($100) + (0.125)($400) + (0.40)($200) +(0.25)($100) $400 + $600 + $500 + $300 + $200 + $400 + $100 + $400 + $200 + $100 = ($344/$3,200) = 0.1075 or 10.75 percent 7.

(a) The new unweighted-average nominal tariff rate is equal to: 0.10 + 0.05 + 0 + 0.30 + 0.02 + 0.025 + 0.15 + ($0.50/$5.00) + 0.40 + ($2.50/$12.50) 10 = 1.345/10 = 0.1345 or 13.45 percent (b) The new weighted-average nominal tariff rate is equal to: (0.10)($500) + (0.05)($750) + (0)($625) + (0.30)($375) + (0.02)($250) + (0.025)($500) + (0.15)($125) + (0.10)($500) + (0.40)($250) + (0.20)($125) $500 + $750 + $625 + $375 + $250 + $500 + $125+ $500 + $250 + $125 = ($411.25/$4,000) = 0.1028 or 10.28 percent

8. A tariff will clearly result in a domestic price that is higher than the world price, and any nontariff barrier will do the same thing. Although we do not have estimates of the size of the nontariff barriers and there may be a combination of a variety of different barriers, the ratio of the domestic price to the world price can serve as an indicator of amount of domestic interference because the restricted supply via any instrument directed toward imports will result in a higher price domestically than exists on the world market. An index greater than 1.0 would indicate that protection is being afforded the domestic industry. 9. Both claims were correct because different tariff rate concepts were being utilized in the statements. Evidence suggests that, at the time, the United States in general had higher effective tariff rates (ERPs) than did countries of the European Economic Community. However, evidence also suggests the opposite with respect to nominal tariff rates – EEC countries appeared to have higher nominal tariff rates than did the United States. VI.

necessarily receive the greatest incentive to expand domestic production. Explain why this is so and how you might go about arriving at a more revealing measure of tariff-based incentives for expanding production. 3. If offshore assembly provisions were extended to include more goods, what would this do to the actual level of protection provided by a country’s nominal tariff schedule? Explain. If the extension of the provisions is made to final goods but not to intermediate goods, what would this do to the effective rate of protection (ERP) for the country provided by its tariff schedule? Explain. 4. Suppose that a country has a nominal tariff rate of 10 percent on good A and imports $100,000 of good A, has a nominal rate of 5 percent on good B and imports $120,000 of good B, has a nominal rate of 12 percent on good C and imports $80,000 worth of good C, and has a prohibitive tariff rate of 50 percent on good D. These are the only four goods in existence. Calculate the country’s unweighted-average nominal rate and its weighted-average nominal rate. Explain in economic terms the relationship you have found between the unweighted- and weighted-average rates. 5. There is often heated debate over what qualifies as a nontariff barrier to trade and how large any trade-distorting effects of NTBs are. Why might this be so? Why do you suppose such debate is less common for tariffs? 6. How would you go about calculating an “implicit” or “equivalent” nominal tariff rate on an imported good that faces a nontariff barrier such as an import quota? What difficulties would you encounter? 7.

(a) Suppose that a country has a nominal tariff rate of 10 percent on good A and imports $1,000 of good A, has a nominal rate of 5 percent on good B and imports $1,400 of good B, and has a nominal tariff rate of 15 percent on good C and imports $600 of good C. These are the only three goods in existence. Calculate the country’s unweighted-average nominal tariff rate and its weighted-average nominal tariff rate. Explain in economic terms the relationship you have found between the two rates. (b) Suppose that, for a country, the free trade price of good X is $1,000 and the free trade prices of the only two inputs (both of which are imported) to the production process of good X are $400 for good W and $200 for good Y. Assume that one unit each of good W and good Y is necessary for the production of one unit of good X. Suppose now that the country, which is a “small” country, introduces a tariff structure that imposes a 20 percent nominal tariff on good X, an 8 percent tariff on good W, and a 6% tariff on good Y. Calculate the Effective Rate of Protection (ERP), or “effective tariff rate,” that this tariff structure provides to the domestic producers of good X. Explain the economic meaning of your result. For what purpose might the ERP of an industry be more useful to an economist than the nominal tariff rate on imports of the industry’s product?

Chapter 14 - The Impact of Trade Policies

III.

Purpose of Chapter

The purpose of this chapter is to explain how trade restrictions affect a country so that the costs and benefits of this type of policy action can be more fully understood. IV.

Teaching Tips

A. The chapter begins with the example of the 2002 U.S. steel tariffs. This case provides a clear indication that there are both winners and losers from this type of trade barrier. In addition, the students will see that losers are not only the foreign exporters that have a tariff applied to their product but also actors within the domestic economy. B. The partial equilibrium analysis relies upon the concepts of producer and consumer surplus to demonstrate the costs and benefits of the various protection instruments. It is therefore important to review these two surplus concepts so that the students feel comfortable with them before they are used in the analysis. C. If you choose to use the large-country approach described on pages 299-311 and in Appendix B, it is worthwhile to stress that the demand for imports schedule is not the entire demand schedule for the product by domestic consumers. The demand for imports schedule is used when we discuss market effects, and the entire demand curve is primarily used when we discuss welfare effects – the two curves should not be confused. Analogous comments apply to the supply of exports schedule and the supply schedule of home producers. The former is used for discussing market effects and the latter for discussing welfare effects. D. We present several different instruments in a variety of settings. You may prefer not to examine all of them due to time constraints. E. We do recommend, however, that within the partial equilibrium model, care be taken to demonstrate the difference between import tariffs, quotas, and domestic subsidies; the effects of an export tax versus an import tariff; and the differing effects of a tariff or import quota in the large-country versus the small-country setting. Basic understanding of these differing situations is necessary for evaluating the effects of trade policy in general. F. It is important to spend some time discussing the general equilibrium effects of protection, even though it is, without a doubt, much tougher going. If you do not wish to spend the time working through the graphical depiction presented in Figure 14 (page 312), you can give students the intuition behind the effects by presenting it as a movement away from the free-trade equilibrium back towards the autarky position. (This just reverses what was done in Chapter 6, except that the country doesn't move all the way back to autarky). As a result, there will be welfare losses due to both a reduction in exchange and in specialization.

G. We encourage the use of offer curves in discussing the impact of protection in the largecountry setting. Once the notion of how protection affects the offer curve is grasped, the diagram provides an excellent vehicle for examining not only the impact of home tariffs but also the impact of retaliatory protection, as well as the differing impact of tariffs, import quotas, and voluntary export restraints. Some students may have heard about the use of VERs and may be very interested in discussing the impact that they have had on the United States. V.

Answers to End-of-Chapter Questions and Problems

1.

The winners are: Producers = (2,000)($1.20) + (0.5)(300)($1.20) = $2,580 Government = (200)($1.20) = $240 The losers are: Consumers = (2,500)($1.20) + (0.5)(100)($1.20) = $3,060 Society’s deadweight losses = (0.5)(300)($1.20) +(0.5)(100)($1.20) = $240; also = ($3,060 - $2,580 - $240) = $240

2. An equivalent subsidy would shift the supply curve down vertically by $1.20. Producers would thus be willing to supply 2,300 units at the world price of $12, consumers would continue to demand 2,600 units, and imports would fall from 600 to 300 units. In this instance, there would be no loss in consumer surplus because the consumer price does not change. Producers would again gain producer surplus equal to $2,580, there would be a deadweight production efficiency loss (society’s total deadweight loss) of $180, and the entire subsidy program would cost the taxpayers (consumers?) $2,760. If the consumers are the taxpayers, they should prefer the subsidy program at a cost of $2,760 in taxes to the loss of consumer surplus under the tariff of $3,060. 3. A quota differs from a tariff in that the quantity of imports is fixed and domestic price adjusts, whereas with a tariff, the domestic price is altered and quantity adjusts. The effects on consumers and producers of a quota are analogous to those of an equivalent tariff. However, there is no tariff revenue generated for the government. The equivalent of the tariff revenue that is generated with a quota (often referred to as the quota rent) can go to the government if the right to import (the quota rights) are auctioned off by the government. If the government does not sell the import quota rights, the quota rent can go to organized foreign producers in the form of higher selling prices, to domestic importing firms as they buy at the lower international price and sell at the higher market-clearing domestic price, or some combination of the two. Yet another possibility is that the governments of the exporting countries could obtain the rent if they auction off export licenses to the exporting firms. 4. You would prefer the quota because in this instance you would receive the benefits of the growth in demand via higher domestic prices and sales without any accompanying increase in imports. With the tariff or subsidy, at least some of the benefits of growth in the domestic 14-2

Chapter 14 - The Impact of Trade Policies

market would accrue to foreign producers in the form of increased foreign exports. A quota also provides greater market certainty for producers. 5. An export tax effectively lowers the price received by producers for their product. They are thus willing to sell at a lower price in the domestic market, as opposed to exporting the good and paying the tax, up to the point where the domestic price is equal to the international price less the export tax. This leads to an increase in domestic quantity demanded, a decrease in domestic quantity supplied, and a decrease in exports. An export subsidy, on the other hand, effectively raises the price received by producers for their exports. Producers consequently raise the domestic price until it is equal to the international price plus the subsidy per unit, which leads to a decrease in quantity demanded at home, an increase in home quantity supplied, and an increase in exports. Domestic consumers would clearly prefer the export tax to the export subsidy. 6. Use of trade restrictions for the small country clearly involves net social losses. The large country can, however, influence world price by its trade policy. The imposition of a tariff in the large-country case reduces the demand for the import good and hence world price, i.e., some of the tariff is passed on to foreign producers through lower international prices. Consequently, the deadweight losses for the tariff-imposing large country will be smaller than for the small country. It is possible that the large country might even experience a gain if the tariff revenue effectively paid by the exporting countries through lower prices is larger than the deadweight losses incurred in the tariff-imposing large country through higher domestic prices. 7. The relevant graph is Figure 14 (page 312) in the text. The loss in real income due to the tariff is shown by the inward shift of the consumption-possibilities frontier (the international terms-of-trade line) as a result of the tariff-induced change in domestic prices and production (the shift in the production point from B0 to B1). The accompanying loss in consumer well-being due to the tariff is shown by the movement from C0 on IC0 to C1 on IC1. Consumer loss would be reduced if an equivalent subsidy were used instead of the tariff. In this case consumers would continue to face international prices and would consume at point C2 on IC2. 8. The export subsidy is more costly in the case of the large country because it not only has to bear the cost of the subsidy, but also ends up exporting the good at a lower international price. The total welfare cost of the subsidy is thus larger than in the small-country case (where international prices remain constant). 9. Consumers pay twice for subsidized exports in that they not only pay a higher domestic price for the subsidized export good but also (as taxpayers) the higher taxes to pay the cost of the subsidy. They thus suffer both a loss in consumer surplus (through higher domestic prices) and a loss in after-tax income. 10. The changes in domestic quantity demanded and supplied can be calculated using the supply and demand elasticities and the increase in domestic price resulting from the 10 percent tariff. 14-3

Chapter 14 - The Impact of Trade Policies

The percentage change in quantity supplied = (0.10)·(elasticity of supply) = (0.10)(1.6) = 16 percent The change in quantity supplied = (0.16)(500) = 80 units The new quantity supplied = 500 + 80 = 580 units The percentage change in quantity demanded = (0.10)·(elasticity of demand) = (0.10)(-2.0) = -20 percent The change in quantity demanded = (800)(-0.20) = -160 units The new quantity demanded = 800 - 160 = 640 units The new domestic price = ($8.00)(1.10) = $8.80 Placing this information along with the initial market information provided in the question on a graph, the familiar partial equilibrium analysis can be carried out using an approach like that used in Figure 3 (page 292) in the chapter. The loss in consumer surplus = ($ 0.80)(640) + (½) ($0.80)(160) = $576 The gain in producer surplus = ($0.80)(500) + (½)($0.80)(80) = $432 The gain in government revenue = ($0.80)(60) = $48 The deadweight losses = (½)($0.80)(160) + (½)($0.80)(80) = $96 VI.

Essay Questions

1.

“The imposition of a tariff on a good will always have a negative welfare effect on a country.” Agree? Disagree? Explain.

2.

“Even if home consumers always have perfectly inelastic demand for a product, at least a portion of the demand curve by those consumers for imports of the product can have the normal downward slope. Further, even if the supply curve of domestic producers is everywhere perfectly inelastic, at least a portion of the supply curve of exports by those producers can have the normal upward slope.” Explain why these statements are true.

3. Discuss why an exporting country II, if faced with a choice between a 100-unit import quota by importing country I on a given product or a “voluntary” export restriction by II of 100 units of the product, would choose the VER. Might there be a larger import quota (for example, 120 units) that would be preferred by II to a 100-unit VER? In general terms, what considerations would be involved in this latter choice? 4. How would an export quota by a home country look in the offer curve diagram? How would a subsequent increase in foreign demand for the export affect the exporting country’s terms of trade and quantity of exports? 14-2

5. At the international price of $20/unit, domestic production is 5,000 units and domestic consumption is 6,000 units. With a 20 percent tariff, domestic production increases by 20 percent and domestic consumption decreases by 25 percent. What is the effect of this tariff on the affected parties? What is the net welfare effect on the country as a whole? 6. Demonstrate why economists argue that, from a country welfare perspective, a domestic subsidy is preferable to a tariff for assisting a particular industry. Use either a partial or a general equilibrium model to support your argument. 7. An import tariff has a similar impact on a country’s export good as an export tax. Explain. 8. Explain, using offer curves, how a tariff affects a large country in the context of general equilibrium. Can a tariff improve the welfare in the tariff-imposing country if both sets of offer curves are elastic in the relevant ranges? Explain. 9. If it has been decided that protection is to be given, industry usually prefers quotas and economic advisers to governments generally argue for subsidies or tariffs. Why might there be a difference of opinion between these two groups? Would it make any difference which was chosen if market demand was constant? 10.

“While the imposition by a country’s government of an import tariff on a good clearly injures the country’s domestic consumers of the good, the tariff helps domestic import-competing producers and enhances overall country welfare (i.e., the “net welfare effect” is positive). Similarly, the granting of an export subsidy by the country’s government to home producers of a good also injures home consumers of the good, but the subsidy helps home producers and enhances overall country welfare.”

Utilizing traditional supply/demand analysis, illustrate and explain the parts of the above statement that are TRUE (if any) and the parts that are FALSE (if any). (You can use a “smallcountry” case throughout your answer. Also, assume that there are barriers to the import of the good into the country granting the export subsidy.) 11.

(a) Using a demand/supply diagram, illustrate and explain the effects of the imposition of an export tax on a good Y by a home country’s government on (i) the home country’s consumers of Y, (ii) the home country’s producers of Y, and (iii) the home government’s tax revenues. (Assume that the country is a “small” country.) Then indicate the “net welfare effect” of the tax on the country. Why might a country want to impose an export tax? Briefly explain. (b) Suppose now that the country imposing the export tax in part (a) of this question is a “large” country rather than a “small” country. Is it an advantage or a disadvantage for a country to be “large” rather than “small” when it imposes an export tax? Briefly explain. (No diagrams are necessary in this part of the question.) 14-3

12.

(a) Suppose that country A wishes to restrict its imports of good X to 900 units per month, which is a reduction from the current quantity of imports. Assume that A also produces good X domestically. In this context, illustrate and explain why the following statement is either TRUE or FALSE. “The reduction in imports to 900 units per month will have identical effects on product price in A, quantity produced in A, and welfare in A whether the reduction is accomplished by the imposition of an import tariff by country A or by country A’s officials persuading foreign governments to ‘voluntarily’ restrict their exports to A to 900 units per month.” (b) Suppose that country A wishes to expand its home production of good Y (as well as employment in country A’s Y industry) by 10 percent, and country A is an importer of good Y. In this context, illustrate and explain why the following statement is either TRUE or FALSE. “The 10 percent increase in home output and employment in the Y industry will be associated with identical effects on product price, quantity of imports of good Y, and welfare in country A whether the 10 percent increase is accomplished by the imposition of an import tariff or by the granting of a subsidy for production and employment to home producers of good Y.”

13.

For each of the three statements below, illustrate and explain why the statement is either TRUE or FALSE. (a) “Other things equal, the imposition of a tariff by a (small) country on an imported good will have a less negative net welfare effect on the country than would the use of a ‘voluntary’ export restraint (VER) by supplying countries of the import, even if the effects on domestic price and the quantity of the good imported are the same in the two situations.” (b) “Other things equal, if a country imposes an export tax of a given amount on a good, then the country can potentially enhance its welfare if it is a ‘small’ country but cannot possibly enhance its welfare if it is a ‘large’ country.”

(c) “Other things equal, if a (small) country elects to assist an import-competing industry in expanding the industry’s output by a given amount, the net welfare effect on the country will be the same whether or not the assistance is given in the form of an import tariff or in the form of a production subsidy to the industry.”

Purpose of Chapter

The purpose of this chapter is to present and assess various arguments for protection. It is particularly hoped that students will learn to think in terms of benefits and costs and in terms of “who gains?” and “who loses?” when encountering these and other arguments in the media and in everyday discussion. A special effort is made to acquaint students with several recent approaches to protection, approaches that are cast in a framework where departures from the competitive trade model exist. Because many industries are clearly not “competitive” in the traditional microeconomic sense and since the newer approaches have received some attention in the press, an understanding of the arguments can be of practical use. IV.

Teaching Tips

A. The chapter begins with a number of statements in support of protection. Evaluating the merit of the arguments is a nice place to begin the discussion in this chapter. B. The macroeconomic interpretation of a trade deficit interests students. It is sometimes helpful also to make the point in terms of S + (T - G) - I = (X - M), in order to focus directly on relatively low saving in the United States and on the U.S. federal budget deficit as being related to the trade deficit. [Note that, strictly speaking, (X - M) is the current account balance, not just the trade balance. However, this distinction isn’t introduced until Chapter 19 (“Balance-ofPayments Accounts”) so we haven’t noted the difference in this chapter.] C. It is useful to stress that the optimum tariff rate can only occur in the elastic range of the foreign offer curve. Only in that range will the imposition of a higher tariff have its positive terms-of-trade impact potentially more than offset by the negative impact of the reduction in the quantity of imports. Hence, only in that range can country welfare start to decrease with a higher tariff, implying that the higher tariff is too high for attaining the “optimum” position. D. In presenting the argument for a “tariff to increase employment in a particular industry,” it is useful to repeat the partial equilibrium graph from Chapter 14 (Figure 4) showing that the home country welfare loss is less with a production subsidy than with a tariff. Students seem to have difficulty accepting that conclusion. E.

the press, you should have no trouble in providing more current examples than are provided in the “In The Real World” box on page 343. Students seem to like these specific examples. F. In fairness to the authors of the various “strategic trade policy” approaches, it should be pointed out to the students that the authors of the theories do not necessarily advocate protection. G. An exercise of interest to the students is to work through a situation like Figure 8 (or Figure 11), but where the home firm’s reaction function is “flatter” than the foreign firm’s reaction function. The equilibrium position is an unstable one. The rationale for the relative slopes drawn in the text is the observation (made by Krugman) that the instability associated with the opposite relative slopes does not appear to characterize these imperfect-competition situations in the real world. H. In covering the material related to Figures 12 and 13, it is useful to stress that the profit of the home firm being greater than the size of the subsidy can mean that home country welfare increases because of the subsidy. This possibility is more certain with the standard assumption that there is no home consumption of the good, since then there is no offsetting loss in home consumer surplus due to the export subsidy’s impact on the domestic price of the good. In general, however, you might want to indicate to the students that welfare impacts are uncertain not only because of possible retaliation and the opportunity cost of the resources used in the export industry, but also because the pre-protection framework in all of these theories is one where market distortions exist. In other words, the beginning situation is one of second-best. I. We have found the Krugman 1987 Journal of Economic Perspectives article to be an excellent outside reading to accompany the material of this chapter. V.

Answers to End-of Chapter Questions and Problems

1. Consider Figure 2 in the text. For a given tariff t and a given starting point, the transfer of foreign profit will be less if demand is more elastic, since distance c1c2 will be the same but the new quantity of imports (0q2) will be smaller. Other things equal, this would diminish the size of any home country welfare improvement because of the tariff. The loss in consumer surplus will also be smaller and, at the limit (perfectly elastic demand), equal to zero. However, since greater elasticity reduces both the transfer of profit and the loss in consumer surplus, it is not possible to determine any general relationship of demand elasticity to the net welfare gain of the home country from the tariff. 2. No, Krugman’s results would not follow. Turn to Figure 9 in the text. In Figure 9(a), the MM curve would slope upward. Protection would cause QQ to shift to the right and would lead to an increase in marginal cost. In Figure 9(b) the result would be a shift of home firm reaction function HH to the left and, with no change in foreign firm reaction function FF, the home firm’s sales in the export market would fall and the foreign firm’s sales would rise. If the foreign firm’s counterpart schedule to MM also sloped upward, the home protection would also lead to an upward shift in FF, which would reinforce these export market share results.

3. No. The reduced costs per unit and ultimately lower consumer prices can then potentially be realized (if they have not already been realized) by the foreign producer as that producer sells to the domestic market (and other markets) under a free-trade regime. Protection for the home firm would achieve no greater cost reductions than would free trade. In fact, protection could reduce world welfare by generating excess capacity in the industry for the world as a whole. Although the protection might result in a shift of any possible “external” benefits from the foreign country to the home country, this would not necessarily improve world welfare. 4. The negative effects on domestic employment caused by foreign retaliation, reduced national income abroad, home currency appreciation, and so forth could, if strong enough, outweigh any immediate positive domestic employment effects. 5. The use of a tariff will raise the price of imports of the good, and the price of the domestically-produced good will also rise as home demand switches toward it. Thus consumers will have their well-being reduced because they will be paying more for each unit of the good and will be buying a smaller quantity because of the higher price. A subsidy given to domestic producers, equal to the per-unit difference between home cost of production and the world price of imports, will cause the domestic industry to expand and provide jobs without having to raise price, and imports will not go up in price because there is no tariff. Consequently, consumers are not injured. Although taxes will need to be levied to finance the subsidy, the taxes are only paid on the units of the good that are produced at home, while the higher price paid when the tariff was used applied both to domestic production and imports. 6. No. The dumping can simply reflect price discrimination by the foreign producer, whereby a lower price is being charged in the importing (home) country than in the foreign exporting country. If the foreign firm is not a price taker, if demand is more elastic in the home country than in the foreign country, and if the markets can be kept separate (e.g., by transportation costs), then such price discrimination maximizes profits. There is no necessary reason for a foreign government subsidy to occur. 7. This statement can be evaluated in the framework of the discussion at the end of the chapter. Exports would be very unlikely to remain unaffected. Further, in the context of the macroeconomic interpretation of a trade deficit, there would not be an improvement in the trade balance unless the tariff increased income relative to spending (C + I + G). 8. Consider Figure 8 in the text and suppose that the H and F labels are switched. If point C is the starting point, the foreign firm is satisfied but the home firm is not since, with 0X2* of foreign sales, the home firm only wants to sell quantity 0X1 (instead of 0X2). The sales combination of the two firms will then move from point C to point B, where the home firm is at its profit-maximizing level, given 0X2* of foreign sales. However, at B, the foreign firm will want to sell the larger quantity 0X1* rather than 0X2*, so movement takes place to point A. This process continues, driving the firms farther away from the equilibrium position E.

9. Yes, the foreign firm will always produce because it makes a profit by doing so, no matter what the home firm does. No, the home firm will not produce the good. Since the foreign firm always produces, the home firm will elect zero profit rather than a $30 million loss. 10. Yes, the production pattern will change. The home firm will now receive $20 million profit if it produces at the same time that the foreign firm produces, and $150 million profit if it produces and the foreign firm does not. Since the foreign firm will still produce despite its reduction in profit from $140 million to $20 million, the production pattern is that both firms are now engaged in supplying the good to the market. However, the subsidy reduces welfare in the home country, since the home firm’s $20 million profit is financed by a $50 million subsidy, implying a $50 million burden on home country taxpayers. 11.

(a) $19. (b) $21. (c) Home country consumer surplus falls by ($21 - $19)(10) + (½)($21 - $19)(14 - 10) = $24 or (½)($21 - $19)(14 + 10) = $24 (d) ($16 - $12)(10 - 0) = $40. (e) The home country “gains” welfare of ($40 - $24) = $16.

12. In Figure 14, the reaction curves for each country show the various tariff rates that maximize that country’s welfare, given different tariff rates for the other country. If the countries find themselves at point F, only country II is on the reaction curve that maximizes its welfare. As country I attempts to maximize its welfare, given that country II has a tariff rate of t*2, it will need to raise its tariff to place itself on the TI tariff reaction function. This movement horizontally to the right of point F will mean that country I is now maximizing its welfare, given country II’s tariff rate of t*2. However, country II will now be off its reaction function, and it will lower its tariff rate until it is back on the function TII. This moves the position downward. Country I will now be off its reaction function and will raise its rate, II will then lower its rate, and so forth, and convergence takes place to point E. Once at E, the chosen tariff rates are such that both countries are simultaneously on their reaction functions and so the countries will stay there. If country I unilaterally moved away from point E by raising or lowering its tariff rate while country II did nothing, country I’s welfare must fall by definition since it no longer has in place the tariff rate that maximizes its welfare given the tariff rate of country II. Analogously, country II’s welfare would fall if it altered its tariff rate from the rate in place at point E and there were no change in country I’s tariff.

Sample Exam Questions

A.

Essay Questions

1. Illustrate and explain how a country could attain its optimum tariff position (optimum terms of trade) on the foreign offer curve by using an import quota rather than a tariff. Could this position also be attained by negotiation of a “voluntary” export restraint (VER) with the foreign country rather than by the use of a tariff? Why or why not? 2. Remembering micro theory, why can it be assumed that home demand for the product of a foreign monopoly supplier (at the initial as well as the post-tariff point) is elastic? Even if the net welfare impact of the “tariff to extract foreign monopoly profit” is uncertain, why is it certain that home consumers will incur less total spending on the good after the imposition of the tariff than before the imposition of the tariff? 3. How would you respond to an argument to impose a tariff on imports arriving from a particular country in order to improve the balance of trade with that particular country? Do the criticisms of the tariff to improve the overall trade balance with all partners apply in this bilateral context? Why or why not? Are there additional considerations to be taken into account? Explain. 4. In the situation of the “tariff to extract foreign monopoly profit,” do you think that the existence of a home producer of the good would strengthen or weaken the case for protection from the standpoint of the impact on home country welfare? Explain. 5. Why might a foreign export subsidy decrease welfare in the foreign country? Why might the foreign country provide such a subsidy despite the adverse welfare effect? 6. Would it be possible for the infant industry argument to be applicable to a perfectlycompetitive industry? Why or why not? 7. It is noted in the text that the infant industry argument is more frequently used in developing countries than in developed countries. Why might this be the case? Does this necessarily have to be the case? 8. Suppose that a relatively capital-abundant country is exporting the capital-intensive good and importing the labor-intensive good, but that the “specific-factors” model of Chapter 8 applies rather than the Heckscher-Ohlin model. Assess the effect on the return to labor of the imposition of a tariff on the labor-intensive good. 9. In the model relating R&D spending to output and output to R&D spending, suppose that, for whatever autonomous reason, the home firm desires to spend more on R&D at each level of output. In this model, what does this greater R&D spending by the home firm do to R&D spending by the foreign firm? Why? Does this result conform to your expectation of foreign firms’ reactions in practice to increased R&D spending by home firms? Explain.

10. Why do you suppose that “reaction functions” are not used in analyzing the market structure of perfect competition (or even monopolistic competition)? If you were to draw reaction functions for any home firm and any foreign firm engaged in perfect competition, what would the functions look like? 11.

(a) Assume that there are only two firms in an industry – a home firm and a foreign firm – and that the firms are competing in third-country markets. (You can have them competing in each other’s domestic markets if you wish.) Explain a “reaction function diagram” for the two firms, including the definition of a “reaction function” in this context and a brief discussion of why the reaction functions slope as they do (although you do not need to derive the functions formally). Then use a reaction function diagram (possibly along with other diagrams) to explain how a “strategic trade policy” action by the home firm’s government can potentially enhance the home firm’s market share in third-country markets. (b) Briefly explain, in a two-country setting, how tariff reaction functions of the two governments can be constructed. Then, in a broader context, briefly indicate why this type of “game” can lead to a need for multilateral trade negotiations (such as those sponsored by GATT/WTO).

Chapter 16 - Political Economy and U.S. Trade Policy

III.

Purpose of Chapter

The purpose of this chapter is two-fold. The first purpose is to introduce students to the political economy of trade policy, and the second is to provide an overview of contemporary U.S. trade policy, focusing on recent developments. IV.

Teaching Tips

A. We have found that students are very interested in the current politics of trade policy and in identifying which groups are currently actively lobbying for changes in trade policy. Beginning this section with a discussion of several of the current political issues and some of the underlying bases for the political economy of trade policy often will stimulate student interest in reading further about key economic and political issues that have influenced recent trade negotiations. B. It is worthwhile to spend some time brainstorming with the class on possible reasons why U.S. citizens’ support of international trade (as reflected in Tables 1 and 2 on pages 368-69) is relatively low. The recent decline in support shown in Table 2 can be tied in with the economic recession and with the point made in Chapter 15 that protectionist tendencies increase in times of relatively high unemployment. C. Since much of this chapter is primarily descriptive/historical in nature, it can be assigned to provide some institutional background to the course and can be left primarily for the students to read on their own. D. If you have a particular interest in this topic area and wish to devote class time to it, a more thorough and rigorous focus on one or two current trade policy issues will help the material become more alive to the students. We have also found that assigning different groups of students particular roles and then having them carry on a short trade policy debate in class is very effective way to stimulate interest in the topic. E. Supplementing the material in the chapter with current material from sources such as The Wall Street Journal, the New York Times, the Washington Post, and The Economist is also a good way to emphasize the relevance of the policy issues discussed in earlier chapters as they relate to the evolution of U.S. trade policy in recent years.

Answers to End-of-Chapter Questions and Problems

1. Legislation favored by a minority may in fact be enacted if the majority simply does not actively participate in the voting process. This may occur because the costs of acquiring information and voting are sufficiently great so that a large group of voters simply chooses not to participate. A second reason this result could come about is because a large number of voters feel that their one vote does not really make a difference or “swing” the outcome and are willing to accept the political result. In either case, the non-participating voter is acting as a “free-rider,” avoiding the costs of participation and accepting whatever result comes about based on those 16-2 © 2014 by McGraw-Hill Education.

who are actively participating. Because members of interest groups in the numerical minority often have more intense interest in and/or more to gain by influencing the political outcome, it is not uncommon to see an outcome that is not consistent with the median-voter approach. 2. Bilateral trade negotiations are superior in that there is greater likelihood of two countries reaching an agreement on reducing trade restrictions than for many countries reaching such an agreement. It is also easier to target certain commodities or policy objectives and/or tailor the trade package to the particular interests of the two countries involved. It makes equal policy reciprocity easier to put into play. On the other hand, the fact that successful multilateral negotiations represent a more significant move toward freer trade means that the potential welfare gains would be greater. There is also the possibility that certain countries might “go along” with the reduction in trade restrictions if every other member of the WTO is participating whereas they might be more reluctant on a bilateral basis, i.e., a “rules-based” trade policy is established with the multilateral negotiations. 3. The presence of protection on consumer goods such as textiles and clothing has continued over the years even though it has been extremely costly to the consumer. This has occurred for several reasons. First, the impact of protection on consumer prices is not transparent, i.e., not clearly apparent to the consumer. The average consumer has little idea of the higher price being paid for the merchandise because of the various instruments of protection on textiles and apparel. Secondly, not only are consumers not knowledgeable of the impact of protection, they also are not sufficiently organized as a group to influence the political process. Further, there is a strong regional aspect associated with this particular product that provides additional political leverage in Congressional negotiations. For example, the textile/apparel lobby is very well organized and strong, particularly on a regional basis. Thus, the potential winners, textile owners and textile labor, have successfully argued for protection over the years on a social objectives platform (personal and regional income) at the considerable expense of consumers at large. (Even with the formal quota removal in January of 2005, tariffs and other restrictions remain.) 4. Concern by the government for the relative income position of a particular group or segment of the economy can foster protection in several ways. First, the government may be less willing to reduce protection on the products that are central to the income of these groups. This is particularly true if there is little support for adopting a direct form of income transfers to these groups if increased trade and the resulting structural change threaten their relative economic well-being. Further, once it is observed that the government will step in with trade restrictions, members of this group will likely become less concerned with efficiency and quality considerations and require increasing amounts of protection to maintain their relative income position. In addition, the knowledge of how the government treats one group may well foster similar behavior on the part of other groups who feel threatened by increased trade. Thus, protection based on a social objective like income distribution not only can result in a short-run policy, but also produce an environment within which continued and often increasing protection will be a necessary norm. Concern with an issue like income distribution need not result in maintaining or even increasing protection and economic inefficiency. Rather than using an indirect method such as trade restrictions to influence the incomes of the groups under consideration, it is far better to adopt policy instruments that deal directly with those in need of 16-2 © 2014 by McGraw-Hill Education.

support. Direct income transfers to those truly in need will not only be a much more effective way to meet income needs, they would also be much less costly to the economy and consumers/ taxpayers than restricting trade. 5. (a) From an economic perspective, TAA should facilitate the movement of resources away from comparative disadvantage industries and towards comparative advantage industries. Since this would make factors less “specific” in nature, it should enhance the short/medium-term gains from trade. The difficulties include such things as funding for the program and being able to ascertain whether the unemployment or profitability problems are due to changes in the trade environment or are simply the results of poor firm management. (b) This should not rule out the use of TAA as a desirable policy. If funds for this type of adjustment, both domestic and trade-related, are insufficient, then the funds should be allocated between the two sources of factor rigidity based on a marginal cost/marginal benefit analysis with the available funds going where the potential net gains appear to be the greatest. In addition, a case can specifically be made for TAA because trade adjustment is distinct from domestic competition adjustment in that the government has changed the “rules of the game” for trade-related firms by altering trade barriers. 6. From a policy perspective, the impact of taxes such as tariffs is relatively well-known and quite easily understood. There tends to be more general support for policy changes that clearly reduce consumer prices. NTBs are, however, less well-understood by and less transparent to the public at large, and there is considerable industry pressure for trade policies (such as quotas or VERs) that seem to have a more certain outcome for the pressure groups. Also, in a growing domestic market, a quota is more appealing to the protected firm than is a tariff because, with the growth in demand, no additional imports are permitted with a quota whereas more imports come in with a tariff. 7. (a) The case for nonreciprocity for the developing countries would logically be built along the lines of an infant industry argument for protection. Until the industries gain experience and sufficient scale economies, they should receive preferential treatment by the developed countries and should be able to protect their own industries until they have attained a cost of production consistent with their comparative advantage. Of course, a normative case can also be built along the lines of giving assistance to poorer countries in the world economy. (b) The use of the nonreciprocity principle tends to maintain an inefficient world production structure. Developing countries, presumably for domestic policy reasons such as greater employment, will use the principle to foster production not only in their comparative advantage industries, but also in industries where they might clearly never have a comparative advantage. 8. If all intervention in agriculture were dropped, then trade and production would reflect comparative advantage. Food prices would decline in those countries that previously had protection and rise in free-trade countries. Agricultural income would decline in the protected countries and rise in the unprotected countries. To the extent that developing countries tax 16-3 © 2014 by McGraw-Hill Education.

farmers and developed countries subsidize farmers, a transfer of real income from developed countries to developing countries should also occur with removal of all agricultural restrictions in general. Finally, world welfare should rise with the movement to free trade. 9. With the imposition of the VER, product prices rise in the importing country. Consumers therefore suffer a loss in consumer surplus. In addition, with the VER, the quota rent (which would be received by the home government with the use of an equivalent tariff or with an auctioning of the quota rights under a domestically-imposed quota) goes to the exporting country. 10. If, for example, interest groups (such as a trade union) are better organized in a particular industry than in other industries, then there will be greater pressure on legislators to adopt trade restrictions favoring that particular industry. If the product in question (e.g., shoes) also constitutes a relatively small share of consumers’ budgets, then there will be little opposition to the imposition of tariffs and other restrictions because the time and money costs to households of gathering and analyzing relevant information may well be greater than the potential consumer benefits of free trade in the product. As another example, scarce factors of production have more incentive to oppose free trade than do abundant factors. If the scarce factors tend to be located in a particular region of the country, then that region’s political representatives, who wish to maximize their chances of staying in office, will push for the restrictive legislation and also may be willing to swap their support for legislation on other matters proposed by politicians from other regions in order to get the restrictive trade policies adopted.

Purpose of Chapter

The purpose of this chapter is to extend the study of trade policy to the situation of discriminatory policy regimes, exemplified by economic integration units such as free-trade areas and customs unions. To acquaint the student with real-world economic integration, considerable attention is devoted to the history of and the continuing liberalization in the European Union. Coverage is also given to integration in North America and other major integration units. IV.

Teaching Tips

A. The chapter begins with a brief look at the enlargement of the EU over time. This provides a nice opportunity to discuss the potential benefits to the EU and why nations would want to join (focusing on real economic benefits apart from the macro difficulties that some EU members are currently experiencing). The “In the Real World” box on pages 399-400 also provides a list of the members of all major integration units. This allows the discussion to move toward the common characteristics of members of integration units. B. In discussing Figure 2 on trade diversion, it is useful to stress that there is some trade creation going on in this “trade-diverting” customs union. The 30 units between 100 and 130 constitute creation in Viner’s sense, because those units represent previous domesticallyproduced units in country A that are now imported from lower-cost partner country B. In addition, the 20 units between 180 and 200 represent creation in a broader sense in that those units constitute trade that did not exist before the union. Only the 50 units between 130 and 180 constitute true trade diversion. The “In the Real World” box on pages 400-02 provides an opportunity to look at actual trade creation and diversion in the original European Community. C. The graph in Concept Box 1 on page 405 may be hard for the students to follow, but we think that its message is a good one. Emphasis on the graph can also test whether the students truly understand the neoclassical trade diagram.

Answers to End-of-Chapter Questions and Problems

1. This customs union has no possibilities for trade creation in the Viner sense because the two countries have no common domestic industries for yielding displacement of a higher-cost domestic industry by a lower-cost partner supplier. However, there are great possibilities for trade diversion. Country A may switch its imports of raw materials and agricultural goods from a low-cost outside world producer to higher-cost B producers, and B may do likewise with respect to its imports of manufactured goods. The trade diversion could still be beneficial if consumption effects are strongly positive, say because of very high preunion tariffs on outsideworld products – although such tariffs would be unlikely in this situation. Of course, dynamic effects could be beneficial as the countries integrated into a larger, more diversified economic unit. 2. The reasoning behind this view is that, because the developing countries produce similar products, they are not likely to be sources for each other of new, different products vital to the development effort. Even granting the questionable assumption that the developing countries are “alike,” however, consideration of trade creation and trade diversion could lead to disagreement with this view of “little gain” from customs unions. Because similar items are being produced in the potential partners, there can be a likelihood of trade creation. In addition, trade diversion will be slight if the potential partners do not possess the capability for displacing the different products being supplied by the outside, developed world. Finally, there can be dynamic benefits from scale economies, etc., as well as potential collective terms-of-trade effects. All of these potential benefits assume, of course, that the developing countries can effectively agree on integration and can surmount the political and distributional difficulties associated with it. 3. The motivation was that the United States feared that Portugal and Spain would, through trade diversion, switch their purchases of some agricultural goods away from the United States and toward other EC members. The threatened U.S. duties were designed to get new exports from the United States to the EC to replace the diverted agricultural goods. The action could be supported on welfare grounds since it actually led to a reduction of some other EC trade barriers and hence to gains from the additional trade. If the action had not been successful and had led to retaliatory EC measures on the United States, welfare losses would have occurred. 4. By reducing (usually eliminating) tariffs only on developing-country goods coming into developed countries, the action is a discriminatory trade policy measure, as is the formation of an economic integration project. Trade can be “created” in that the new developing countries’ exports displace previous high-cost domestic production within any given GSP-granting developed country. The GSP also diverts imports from other developed countries into any given

Chapter 17 - Economic Integration

developed country, switching imports from a lower-cost to a higher-cost source (the developing countries) that was not exporting as much to the developed country with the uniform tariff structure. 5. Trade diversion against U.S. exports could have occurred as barriers within Europe were dismantled. Further, dynamic effects such as enhanced technology and scale economies could have made the EU a more formidable export threat in third-country markets as well as in the U.S. market. However, if the EU grows more rapidly, it can be in a position to purchase more U.S. goods. Also, U.S. foreign investors expanding into Europe may source their inputs from the United States. Whether or not one should be enthusiastic or worried obviously depends on the size of the costs to the United States relative to the benefits. Certainly greater growth in Europe can potentially benefit U.S. welfare, but, if the result of the integration is the formation of two hostile trading blocs (Europe and North America), there can be overall detrimental impacts. 6. It can be argued that the development of APEC and the Trans-Pacific Partnership alongside the efforts in the Western Hemisphere (e.g., NAFTA) represent a movement toward world free trade in that there are several members (Canada, Chile, Mexico, and the United States) that are participants in both APEC and integration efforts in the Western Hemisphere. For these countries their simultaneous participation in both movements represents a significantly greater step towards worldwide free trade and increased benefits of integration than do either of the movements alone. This follows from the knowledge that the net effects of integration are greater, the larger are the number of participants in free trade agreements and the larger the economic size of the participants. 7. U.S. workers, especially in labor-intensive industries, worried that freeing up trade with labor-abundant Mexico would cause U.S. workers to lose their jobs or receive lower wages. These results were thought to be even more likely because U.S. firms will also switch production to Mexico because of the lower wages there. Hence, fears arose and continue to arise because of the perceived increased job/wage insecurity due to NAFTA. Other concerns have been raised about inadequate environmental protection and about “unfair” trade since Mexico’s labor standards are lower. In addition, with NAFTA, there is joint arbitration of some trade disputes by representatives of all three nations, and this feature led to U.S. fears of loss of national sovereignty. The second part of the question is clearly a judgment call on the part of the person answering the question. In the static sense, the trade creation effects of NAFTA must be compared to the trade diversion effects, taking into account any accompanying costs of adjustment. Of greater importance, however, are the dynamic effects that can accompany the increased trade among the three countries. Insofar as integration fosters greater efficiency and higher productivity through increased specialization, reduces problems of illegal migration with Mexico, increases consumer well-being through lower import prices, and is not accompanied by major structural adjustment problems, the benefits can clearly be positive. 8. (a) The basis for this statement is the fact that specific coalitions contain elements of both trade creation and trade diversion. The static effects of these coalitions can thus be negative if trade diversion effects are greater than trade creation effects, whereas no trade diversion

Chapter 17 - Economic Integration

effects occur with a general lowering of protection by everyone. In addition, there is the fear that once members of the coalition(s) have reduced tariffs with each other they will be less interested in further reductions in protection with nonmembers. There is also the fear that the new coalitions may actually raise their external tariffs to nonmembers, generating a group of trading blocs that would represent a movement away from freer trade. (b) The establishment of new trading coalitions should be encouraged because they represent a clear first step towards freer world trade. This is particularly so if the coalitions adopt common external tariffs for nonmembers which are lower than those in existence in each country prior to their integration. Further, to the extent that there are economies of scale present, the larger coalition market will allow coalition members to produce goods more cheaply and thus have less need for protection in general. Finally, experiencing both the static and dynamic economic gains that accompany the smaller coalitions will make them more open to reducing trade barriers on a worldwide basis. VI.

Essay Questions

1. Jacob Viner originally envisioned a situation where, in the demand/supply graph of a trade-diverting customs union, the demand curve was vertical and all supply curves (including the supply curve of domestic producers) were horizontal. In this situation, could the tradediverting customs union ever enhance the home country’s (country A’s) welfare? Explain. 2.

(a) Define “trade creation” in the context of the formation of a customs union. Then, using a demand/supply diagram of a (small) home country for a good that is produced at home and would be imported if there were no tariff, illustrate and explain how the formation of a pure trade-creating customs union can enhance the country’s well-being. What factors would be conducive to a greater rather than a smaller gain from the trade creation? (b) Define “trade diversion” in the context of the formation of a customs union. Then, using a demand/supply diagram of a (small) home country for a good that is both produced at home and imported, illustrate and explain how the movement from a situation of a uniform tariff on imports of the good from all countries to a situation of a trade-diverting customs union with one particular country can affect consumer and producer surplus and government revenue in the home country. Why can we not be sure that welfare in the home country will rise? Under what general conditions would it be likely that this trade-diverting customs union would injure welfare in the home country?

3. Other things equal, would the formation of a customs union with many members be more likely or less likely to improve welfare for a given member country than the formation of a customs union with only a few members? Why or why not? Other things equal, would the formation of a customs union be more likely or less likely to enhance welfare for a given member country if that country had very high preunion tariffs than if it had very low preunion tariffs? Why or why not?

Conceptually, why could the additional step of moving from a customs union to a common market not result in any movement of labor and capital between the two countries? Explain. 5. How could the formation of an economic integration unit among several countries actually result in the countries trading to a greater extent in absolute terms with the outside world than before the union was formed? What factors would you consider in assessing whether this result would be likely to occur? Explain. 6. When the European Community was originally formed, it was determined that the common external tariff on outside world products should be equal to the average of the preunion tariffs of partner countries on the outside world. This rule was adopted so that there would not be a net increase in protection against the outside world. Thus some partners raised tariffs on some products and lowered them on others. Demonstrate how this “averaging” rule would complicate the process of making welfare judgments about the likely effects of the original formation of the EC on the member countries. B.

Chapter 18 - International Trade and the Developing Countries

III.

Purpose of Chapter

The purpose of this chapter is to review the general links between international trade and economic development and to summarize key problems that exist (or are alleged to exist) with respect to developing countries and their trade sector. Possible causes and consequences of the potential trade difficulties are examined. Policy options are considered that might help to obtain a more favorable contribution of trade to development and to accelerate growth in the less developed countries (LDCs). The chapter concludes with a specific focus on the debt problem of the developing countries. Some possible solutions to this debt problem also are suggested. IV.

Teaching Tips

A. U.S. college students often have little conception of the vast differences between their own living standards and those in the LDCs. Table 1 provides data necessary to understand the economic conditions in developing nations. The chapter then takes a look at the least developed countries in the world and the myths associated with their trade. Anything you can do to supplement and to bring life to these data would be very helpful. B. Presentation of a numerical example can help the students in understanding how transfer pricing can work against the host developing country. C. There seems to be some feeling among economists that the terms-of-trade issue is a “dead issue.” However, we recommend dealing with it because it seems very much alive in political science courses that students may be taking. D. In discussing “inward-looking” versus “outward-looking” strategies, it is important to note that government played a large role even in the “strongly-outward-oriented” cases of South Korea and Singapore. Students should not conclude from this section that the public sector should always get out of the way. E. The IMF’s semi-annual publication World Economic Outlook (appearing in April and September) provides updated information on the debt situation as well as projections for future years. V.

Answers to End-of-Chapter Questions and Problems

1. According to trade theory, countries should specialize in and export those goods and services that use relatively-intensively their relatively-abundant factor. Because the LDCs are often labor/land-abundant, the static gains from trade would result from their expanded production and trade in goods intensive in these factors. Their trading partners, the industrialized countries (ICs), would, on the other hand, be specializing in goods that are relatively intensive in capital. Thus, the gains from trade and the relative income distribution effects accompanying trade would tend to reward labor/land in the LDCs and capital in the ICs. 2. This question is obviously focusing on the dynamic gains from trade that are discussed early in the chapter. The dynamic effects of trade are related to such phenomena as 18-2 © 2014 by McGraw-Hill Education. This is proprietary material solely for authorized instructor use.

Chapter 18 - International Trade and the Developing Countries

demonstration effects associated with exposure to new products and cultures, possible increased international investment, exposure to new technologies, economies of scale associated with enlarged production, benefits of increased competition (reduction in monopoly market leverage), etc. 3. These arguments focus on the static effects of international trade discussed in the first question. Following the dictates of comparative advantage, many developing countries could find themselves specializing in labor/land-intensive production rather than more capital-intensive production. Such a situation could lead to several problems. First, labor/land-intensive products often have lower income elasticities of demand than do capital-intensive manufactures. Consequently, the demand for labor/land-intensive products grows relatively more slowly and the countries producing these goods find their growth in exports lagging behind export growth in the ICs. Further, the LDCs’ own demand for imports may outgrow their export growth leading to balance-of-payments and debt problems. In addition, the low price elasticities of LDC export products tend to make LDC annual export revenues more erratic. Because of these production effects they may find themselves increasingly dependent upon foreign technology and international financing. Finally, by not focusing more on the effective use of capital, the consequent increase in labor productivity (and hence wages) is retarded and, relatively speaking, the gap in per capita income between the ICs and the LDCs may widen. 4. Basic reasons why export price (and earnings) instability is judged to be a problem are indicated in the chapter. Price instability seems more likely to occur for LDCs than for ICs because demand and supply elasticities are lower in LDCs, because shifts in the curves may be more frequent for LDCs, and because LDC exports are more heavily concentrated by commodity. These features reflect the relatively greater reliance on the export of primary products by the LDCs than by the ICs. 5. The long-run deterioration of the commodity terms of trade suggests that, other things equal, welfare is less for the LDCs than would otherwise be the case; for the ICs, it is greater, so there has in effect been a transfer of welfare to the ICs from the LDCs. A “worst case” of deterioration would be represented by the immiserizing-growth situation, where the outward shift of the PPF from an LDC’s growth results in such a deterioration of the terms of trade that the country ends up on a lower indifference curve after growth. However, the income terms of trade might have improved. 6. The diversification could mean that the price instability would be less because demand and supply curves for manufactured goods are generally more elastic than for primary products. Also, the diversification by definition would mean less of an “eggs in one basket” phenomenon. Regarding the terms-of-trade deterioration, diversification would mean movement into products with higher income elasticities of demand in the buying countries, and perhaps a greater ability by LDCs to avert downward wage movements associated with the unorganized labor markets in the primary product sector. With respect to the terms of trade, protection against the new LDC manufactured products might arise, which could offset the favorable effects of the higher income elasticities of demand. 18-3 © 2014 by McGraw-Hill Education.

Chapter 18 - International Trade and the Developing Countries

7. If the larger market size generated by an economic integration project permits scale economies and efficient production, the LDCs might consequently diversify by exporting to each other (or even to the outside world). There could also be other dynamic effects such as the attraction of direct foreign investment from the ICs. Further, if the same primary products are exported to the ICs by the member LDCs, some market power might now be exerted. With respect to static effects, trade diversion might outweigh trade creation if the LDCs began to produce some of the manufactured products formerly imported from ICs, but this may not be the result. (See the answer to End-of-Chapter Question #2 in Chapter 17 in this Instructor’s Manual.) The formation of the coalition might also mean lower quality, lower-tech manufactured goods imports than had previously been the case. Whether such LDC unions should be recommended depends on a more precise assessment of the effects in each situation, but a cautionary note is provided by past experience (such as happened historically with the original East African Common Market). 8. A reduction in the debt burden can make for greater stability and growth in the world as a whole, and it is in the interests of both the developed countries and the developing countries to seek solutions to the debt problems in LDCs. Some argue that a reduction in debt might in fact enhance the likelihood that the LDCs will repay debt and help the lending banks as well. In cases where the debt burden is so high that default is a real possibility, the forgiveness may be the key to preventing default. If the LDC has a smaller debt burden and reduced possibility of a future need to raise taxes to deal with debt service and repayment, foreign investment may also be more attracted to the LDC. 9. The developing countries are not blameless, because they have often pursued inappropriate domestic policies involving price distortions, rapid inflation (leading to capital flight), usage of loans for purposes other than development, etc. Since internal factors have been important in generating the problem, a case can be made that debt should not be relieved unless countries make changes that improve the long-term ability to service their debt. In fact, a potential moral hazard problem is created if improper use of funds and poor policy choices appear to be rewarded by debt forgiveness. VI.

Purpose of Chapter

The purpose of this chapter is to present the basic principles of balance-of-payments accounting and to discuss the several concepts of “balance” in a country’s balance of payments. With a working knowledge of balance-of-payments concepts in hand, students will be better able to understand the operation of foreign exchange markets, which are discussed in succeeding chapters. IV.

Teaching Tips

A. Students often find balance-of-payments accounting uninteresting. However, in recent years, U.S. trade deficits, and particularly the deficits with China, have been continuously in the news. The opening vignette in this chapter provides background on this issue and will hopefully get students thinking of the importance of understanding what BOP surpluses and deficits mean and when they might be of concern to policymakers. You can also use this case to illustrate the point that a trade surplus of a country with one trading partner does not always accurately reflect the overall situation – a surplus with one trading partner is often associated with deficits with 19-1 © 2014 by McGraw-Hill Education.

other trading partners. B. The financial account classifications in the debit and credit categories are often difficult for students to understand. Sometimes it is helpful to stress that debit items are items that, other things equal, reflect an increase in the net claims ( assets - liabilities) of the home country on foreign countries (increase in foreign assets owned by home country citizens or government, decrease in home country assets owned by foreign citizens or government). Credit items reflect, other things equal, an increase in net claims of foreign countries on the home country (decrease in foreign assets owned by home country citizens or government, increase in home country assets owned by foreign citizens or government). C. In the balance-of-payments sample transactions, transaction 7 was included in order to bring Category III into the examples. You may want to indicate that this type of transaction is unlikely to occur very often in a world of basically floating exchange rates, but that it can be common in a regime of fixed rates. D. In your discussion of the U.S. balance-of-payments material, point out that the U.S. Department of Commerce separates out “investment income” from “services.” However, investment income is economically a service payment for the use of capital, so it should logically be included in “goods and services” rather than presented in a separate category. E. In the discussion of the net international investment position, note that the U.S. Department of Commerce is currently using “replacement cost” rather than “original cost.” You may want to check the latest September issue of the Survey of Current Business for data using “original” or historical cost and compare this information with the replacement cost figures of the text (and which appear annually in the July issue of the Survey of Current Business).

1. The initiating entries would be as follows (not enough information is generally given to ascertain the accompanying offsetting debit or credit entry): wheat shipment – credit entry in category I under “exports of goods;” the accompanying debit entry would be in category I under “unilateral transfers made” textile machinery imports – debit entry in category I under “imports of goods” Zurich bank account – debit entry of $500 in category II, “increase in U.S. short-term private assets abroad” Japanese purchase of U.S. government bonds – credit entry of $1,000,000 in category II, “increase in foreign long-term assets in the United States” Geneva hotel expenses – debit entry in category I under “imports of services” purchase of BMW – debit entry in category I under “imports of goods” 19-2 © 2014 by McGraw-Hill Education.

interest earned in London – credit entry in category I under “exports of services” purchase of chemical plant – debit entry in category II, “increase in U.S. long-term assets abroad” lumber sales to Japan – credit entry in category I under “exports of goods” shipment of Fords from Mexico – debit entry in category I under “imports of goods;” profits earned in the Mexican plant – credit entry in category I, “exports of services” 2. The financial account in the balance of payments indicates the net asset transfers between the home country and foreign countries during the time period under consideration. A net debit balance (financial account deficit or net capital outflow) indicates that home country wealthholders increased their holdings of foreign assets relative to foreign wealthholders’ ownership of home country assets. A net credit balance (financial account surplus or net capital inflow) indicates the opposite. The current account reflects the net effect with respect to foreign countries of the sources and uses of home country current income during the time period. A net debit balance (current account deficit) indicates that current income used to purchase imports of goods and services and to make unilateral transfers abroad exceeded current income generated by exports of goods and services and the receipt of unilateral transfers from abroad. A net credit balance (current account surplus) reflects the opposite. 3. The “net international investment position” shows the total existing stock of foreign assets (physical and financial) owned by U.S. citizens and government minus the total existing stock of U.S. assets (physical and financial) owned by foreign citizens and governments. If the United States experienced a current account surplus, the U.S. net international investment position would increase. Foreign payments to the United States for exports of goods and services and for unilateral transfers would exceed U.S. payments for imports of goods and services and unilateral transfers. This would result in a net buildup of U.S. ownership of foreign assets relative to foreign ownership of U.S. assets. 4. A country can have an official reserve transactions surplus that is larger than its merchandise trade surplus if phenomena such as an export surplus in services, a net inflow of unilateral transfers, and a net private capital inflow occur. In China’s case, there has been a relatively small services surplus in some years but a small deficit in others. However, the official reserve transactions balance (overall balance) has been substantially larger than the merchandise trade surplus (and the current account surplus) because there has been a huge inflow of direct investment in particular. 5. Keeping track of the financial account provides information on the specific nature of developments in the relative holdings of foreign assets by domestic citizens and government and home country assets held by foreign citizens and government. For example, the analyst can examine the extent to which the asset changes have been concentrated in short-term assets, longterm assets (and direct versus portfolio assets), private assets, or official assets. Developments in these various asset categories have different implications as to the speed with which the financial account can change in the future and for the size of investment income flows that will occur in the future. In addition, since the financial account estimates never match the current account 19-3 © 2014 by McGraw-Hill Education. This is proprietary material solely for authorized instructor use.

figures in practice, examination of the magnitude of the resulting statistical discrepancy can be useful for assessing the size and nature of the gaps that exist in the data-collection network. 6. Since Y = C + I + G + (X - M), the current account balance can be defined as (X - M) = Y - (C + I + G). With a current account deficit, (X - M) < 0 or, therefore, Y < (C + I + G). Because Y indicates production in the economy and (C + I + G) indicates total spending by the country’s residents (or the use of goods and services), the fact that Y < (C + I + G) means that the country’s use of goods and services is greater than the country’s production. 7. When the initial investment is made, say the purchase of a foreign production facility by a Country A firm, there is a debit in the long-term financial account of country A (“increase in long-term assets abroad”) and a credit in A’s short-term financial account (either an “increase in foreign short-term assets in country A” if the foreign firm selling the facility is given a bank account in country A, or a “decrease in A’s short-term assets abroad” if payment is made from the A firm’s bank balance abroad). Over time, A’s current account can be affected in a variety of ways – for example, exports from A of components to the new facility can take place, final goods imports into A from the facility can occur, and profits may be repatriated to A. Of course, if A’s currency depreciates because of the initial capital outflow, this can alter A’s current account immediately. 8. In balance-of-payments accounting, the transactions would be recorded for country A as follows: ITEM (1): Credit: Category I, Exports of goods, + $1,000 Debit: Category II, Increase in short-term assets abroad, - $1,000 ITEM (2): Debit: Category I, Unilateral transfers made, - $500 Credit: Category II, Increase in foreign short-term assets in A, + $500 The merchandise trade balance improves by $1,000 (the credit entry for exports); the current account balance improves by $500 (the sum of the $1,000 export credit entry and the - $500 unilateral transfers entry); the official reserve transactions balance has a net effect of zero [the $500 improvement in the current account is matched by the - $500 change (- $1,000 + $500) in the short-term private assets account. 9. There is validity to this point because of the identity (X - M) = S + (T - G) - I. A reduction in the U.S. federal government budget deficit, assuming other right-hand-side variables are constant, would reduce (T - G) and therefore decrease (X - M).

Essay Questions

1. Why might detailed information on the state of the balance of payments be useful to economists and to policymakers? Which of the five “balances” discussed in the text does the U.S. Department of Commerce not publish, and what case can be made for not publishing those balances? What case can be made that those balances should be published? 2. Suppose that home country A has the following transactions with foreign countries (represented by foreign country B). For each transaction, indicate and explain the appropriate debit and credit entry in A’s balance-of-payments accounts. (a) A firm in country A sells $6,000 of steel to a country B firm. Payment is made by the firm in B drawing down its checking account in a country A commercial bank. (b) Country A citizens give $1,000-worth of cash to country B relatives by writing checks on A-citizen bank accounts in country B. (c) An importer in country A buys $8,000 of apparel from a country-B supplier, paying for the goods by writing a check to be deposited into the B firm’s bank account in a country A bank. (d) A citizen of country B buys a long-term bond of a company in country A. The buyer purchases the $5,000 bond by drawing down his/her checking deposit in a bank in A. (e) A firm in country A purchases $3,000 of shipping services from a country B ocean freight carrier, paying for the services by drawing down bank deposits in B owned by the A firm. (f) A’s central bank buys $2,000-worth of foreign currency holdings held in a B commercial bank by an A citizen. The central bank adds the foreign currency to its own commercial bank account in country B. Next, using the debit and credit entries that you have constructed, and assuming that these six transactions were the only international transactions during the time period, construct country A’s balance-of-payments summary statement for the time period. Indicate the size for country A and explain the meaning of the “balance of trade,” “balance on goods and services,” “current account balance,” “official reserve transactions balance,” and “financial account balance.” 3. Suppose that you had to explain to a person in the street (who is not an economist) why a current account deficit must be accompanied by a financial or capital account surplus. What would you say?

4. “Since the statistical discrepancy in the U.S. balance-of-payments accounts is so large, we cannot rely on the U.S. BOP statement to give information on the size of various ‘balances’ with any precision. Perhaps the U.S. BOP statement is essentially useless.” Discuss this statement. 5. How is a country’s net international investment position related to that country’s balanceof-payments accounts? When might the net international investment position not change from the end of one year to the end of the next year? Explain. 6. Identify and distinguish among, in balance-of-payments accounting, various “balances” that can appear in a country’s balance-of-payments statement. What must conceptually be the numerical relationship between a country’s “balance on current account” (or “current account balance”) and its “capital/financial account balance?” Why? Then, for each of the two statements below, explain why the statement is either TRUE or FALSE. (a) “A rise in interest rates in a country, such as occurred in the United States in the early 1980s, can lead to an increased deficit in the country’s merchandise trade balance.” (b) “A decrease in saving by households in a country can lead to a deterioration in that country’s balance on current account (i.e., can make the current account balance less positive or more negative).” 7.

For each of the statements below, explain why the statement is either TRUE or FALSE. (a) “If a country’s income is less than its spending, then the country will have a surplus in its current account.” (b) “If a country has a merchandise trade deficit, then the country must also have a current account deficit.”

(c) “If a country’s balance on current account is a net debit of $5,000, then the country’s capital/financial account balance (including all government capital/ financial flows as well as all private capital/financial flows) must show a net capital/financial inflow of $5,000.” (d) “If country A makes a unilateral transfer of $1,000 of goods to country B, then, in this time period and other things equal, country A’s merchandise trade balance will be $1,000 more positive than would otherwise have been the case. However, country A’s current account balance will be the same as would otherwise have been the case.” 8. When might a current account deficit be a reflection of the fact that “good things” are happening in the economy? B.

III.

Purpose of Chapter

The purpose of this chapter is to introduce students to the nature, components, and functioning of the foreign exchange market. Special attention is focused on the links between the foreign exchange market and the money markets. IV.

Teaching Tips

A. Describing the relative movement of the dollar in recent years and its impact on U.S. consumers, firms, and citizens traveling abroad is a good way to generate interest in exchange rates. This chapter introduces some of the different factors that influence exchange rates and makes the student aware of the difficulties involved in predicting exchange rate movements. B. Students often have difficulty relating the terms “appreciation” and “depreciation” to the price of foreign exchange and the graphical analysis. It is therefore important to make them comfortable with changes in the market price and what it means in terms of the cost of foreign exchange. C. It is increasingly common to read about different exchange rate concepts in the news media. We therefore have devoted more space than is usual in texts to explaining what the various measures are and of what use they are to the international business person/traveler. If you are pressed for time, you may find it advantageous to leave this material for students to read on their own. We do, however, think that it is important that students be exposed to these different exchange rate concepts. D. We suggest that you take time to introduce the PPP concept at this point. Understanding this concept is critical for the discussion of the monetary approach to the balance of payments which follows in Chapter 22. E. In a one-semester course in trade and finance, it is unlikely that you will have the time in class to discuss the forward and futures markets and the futures options market in the detail presented in the text. However, if you are teaching a one-semester course in international monetary economics, it is a topic that students find interesting and worth spending time on. This material is especially important if you plan to cover part or all of the material on international financial derivatives which follows in Chapter 21. F. It is important to show how the foreign exchange markets are linked to the domestic money markets, particularly at this point in time when financial markets are becoming more completely integrated worldwide. Although there are a number of ways of doing this, we have found the method used in Figure 8 at the end of the chapter to be particularly effective. Establishing the link between the foreign sector and the money markets is a useful transition from the micro-trade section to the international macro section.

Answers to End-of-Chapter Questions and Problems

1. If Japan were to reduce its investment in the United States, the supply of foreign exchange (Japanese yen) would be reduced, i.e., there would be a shift to the left from Stotal to S’ as indicated below. With the decrease in the total supply of foreign exchange, the U.S. dollar would depreciate, leading to a reduction in the current account deficit from AB to CD below.

2. No, there is not cross-rate equality, since ($.0075/yen)/ (£.005/yen) = $1.50/£, not $2.00/£. Consequently, arbitragers would use dollars to acquire yen, use yen to acquire pounds, and use pounds to acquire dollars, thus making a quick profit. In the process, the dollar price of the yen would rise, the yen price of the pound would rise, and the dollar price of the pound would fall (pound price of the dollar would rise). 3. This statement is true. Unless one knows what happened to relative prices in the two countries concomitantly with the appreciation of the dollar, it is impossible to evaluate the new purchasing power of the dollar. What is required in this instance is a real exchange rate. 4. The real exchange rate provides an estimate of the purchasing power of a currency relative to some previous period by removing the effect of price changes in each country by using their respective price indexes. Relative PPP, on the other hand, provides an estimate of the equilibrium exchange rate based on the change in relative country prices compared to some previous period. The PPP estimate is then compared to the current exchange rate to ascertain if the currency is currently overvalued or undervalued. (See the text for the calculation of each of these measures.) 5.

Given the 2008 exchange rate of 13.9 peso/$, PPPrel would suggest that the peso is overvalued (the dollar is undervalued), since the peso commands more dollars than expected, given the relative change in prices in both countries since 2005. 6. The condition for equilibrium in this instance is that iNY ≈ iLondon + xa - RP [or (iNY iLondon) ≈ xa - RP]. In this example, the rate of return in New York is less than the expected rate of return in London after accounting for expected depreciation of the pound and the required 20-3 © 2014 by McGraw-Hill Education.

payment for risk associated with the U.K. investment, i.e., 0.02 < 0.06 + (-0.01) - 0.02, [or (0.02 - 0.06) < (-0.01 - 0.02)]. As a result, investment funds should flow from the United States to the United Kingdom. This raises the spot rate on pounds and, other things equal, reduces xa since xa equals [E(e)/e] -1. In addition, there should be upward pressure on the interest rate in New York, downward pressure on the interest rate in the London, and a possible increase in the risk premium (due to the increased exposure in the United Kingdom). These adjustments should take place until iNY is approximately equal to iLondon after taking account of the expected depreciation of the pound and the required risk premium. 7. For the financial markets to be in equilibrium, the difference between the interest rates in the two countries should be approximately equal to the forward premium, after taking account of any financial transactions costs. In this problem, (0.038 - 0.025)/4 is compared to (1.8180 – 1.8034)/1.8034. Since the difference between the two, 0.00325 compared to 0.00810, exceeds the estimated transactions cost of 0.0020, one would conclude that the markets are not in equilibrium. 8. With an increase in the U.K. interest rate, there is an incentive for short-term financial investments to move from the United States to the United Kingdom. As these flows take place, they will lead to upward pressure on the interest rate in the United States, appreciation of the spot pound, depreciation of the forward pound, and downward pressure on the U.K. interest rate. Investments should continue to flow into the United Kingdom from the United States until the adjustments in the markets cause the appropriate interest rate differential between the two countries to be approximately equal to the forward discount in the foreign exchange markets. 9. (a) The Swiss franc was at premium with respect to the dollar since the forward rate is greater than the spot rate (in $/Swiss franc). The percentage premium is equal to [(efwd/espot) - 1] = [($1.0685/$1.0670) - 1] = 0.1406 percent. This result is reasonably consistent with covered interest parity. For covered interest parity to hold, (iUS - iSwitzerland)/4 ≈ (efwd - espot)/espot or (efwd/espot) - 1. In this instance [(0.0325 - 0.0052)/4] = 0.006825 > [($1.0685 - $1.0670)/$1.0670] = 0.001406. Strictly speaking, investment funds should thus be moving to the United States until the interest parity condition is realized. However, if transactions costs are in the neighborhood of 0.50 percent (or 50 basis points), this situation is already almost one of arbitrage equilibrium. (b) In this example the dollar is at discount relative to the yen (the yen is at premium relative to the dollar) because the forward rate on the dollar is less than the spot rate. The percentage discount is equal to [(¥79.24/¥79.31) - 1] or -0.0009 percent. If transactions costs are thought to be in the neighborhood of 0.50 percent, the result is consistent with covered interest parity. The difference between the forward discount and the interest rate differential {[(0.01475 - 0.0325)/4] = -0.0044 < [(¥79.24 - ¥79.31)/¥79.31] = -0.0009} equals 0.35 percent (or 35 basis points), and there should be little or no incentive to move funds between the two countries. In the absence of transactions costs, funds should move to New York from Japan until the parity condition is realized. (Note: Make sure that the students realize that a more negative number is a smaller number, i.e., -0.0044 is less than -0.0009.)

10. If all markets are working efficiently, then the 1.2 percent 3-months forward premium should equal the expected forward premium (and hence the expected appreciation of the Swedish krona) if the difference between a higher 3-months interest rate in the United States and the interest rate in Sweden, adjusted for the presence of any risk premium and transaction costs, approximately equals 1.2 percent. However, the existence of capital market imperfections, information costs, non-comparability of country assets, and political risk can make it difficult to strictly interpret the forward premium as being a good indication of expectations regarding the movement of the krona over the next three months.

Essay Questions

1. Explain the difference between the spot rate, the forward rate, the real exchange rate, and the effective exchange rate. Then discuss a situation in which you would use each of these different exchange rates. 2. If interest rates differ between two countries, it is an indication that the financial markets are not in equilibrium, and that investment flows should be taking place between the two countries. Agree? Disagree? Explain. 3. Balance-of-payments accounting indicates that any surplus (deficit) in the current account must be offset by a deficit (surplus) in the financial account. Explain why this is so, using demand and supply curves of foreign exchange. Suppose that a country had a current account surplus. What would you expect to happen to the current account balance if there were a relative decline in the domestic interest rate? Why? 4. You note that over the last five years, the Swiss franc has appreciated from Sfr 1.60/$1 to Sfr 1.45/$1. During that same period, the U.S. consumer price index rose from 100 to 120 and the Swiss consumer price index rose from 100 to 105. On the basis of these movements, would you expect the Swiss to be buying more or less U.S. goods? Why? Would you advise a foreign exchange speculator to buy Swiss francs at this point or to change Swiss francs into U.S. dollars? Why or why not? 5. How do speculators and arbitragers affect the foreign exchange market? Briefly describe the different ways that arbitragers can “cover” themselves in the foreign exchange market. Finally, will speculation in foreign exchange always have a stabilizing effect on the foreign exchange market? Why or why not? 6. You and a friend get into a heated discussion about the value of the U.S. dollar in which you argue that the dollar is currently undervalued against the Japanese yen. Failing to resolve the issue, you decide to prove that your position has the greatest economic merit given what you have recently learned in your international economics class. How might you go about trying to demonstrate to your friend that you are correct and that, indeed, the dollar is undervalued?

7. Indicate the meaning of the terms “covered interest parity” (CIP) and “uncovered interest parity” (UIP). Then, focusing on “covered interest parity,” explain by numerical example and with at least one graph how such parity is conceptually attained in the context of a home country and a foreign country if the short-term interest rate in the foreign country is greater than the short-term interest rate in the home country at the same time that the spot rate on the foreign currency equals the forward rate on the foreign currency. (Assume that the two interest rates are on comparable assets of the same risk.) 8.

(a) Why does a “demand for foreign exchange” exist by a country’s economic actors? Explain. Why does this demand curve have its downward slope? Briefly explain. (b) What economic actions give rise to a “supply of foreign exchange” to a country? Explain. Can we be sure that this supply curve will always have an upward slope? Briefly explain. (c) Finally, put a demand curve and supply curve of foreign exchange together and indicate the equilibrium exchange rate. Then explain how and why the equilibrium exchange rate would change if there were a sudden increase in the supply of foreign exchange to the country.

9.

(a) Draw a demand curve for foreign exchange (spot foreign exchange) by a home country and briefly indicate why the curve has a downward slope. Then draw an upwardsloping supply curve of foreign exchange to that country. (You do not need to explain why it is upward-sloping.) Then indicate the equilibrium exchange rate in this spot market and briefly explain why the market moves to this equilibrium position. (b) Define the “forward market” for foreign exchange, draw a demand curve and supply curve for the forward market, and indicate the equilibrium forward exchange rate. Assume that the equilibrium forward exchange rate is identical to the equilibrium spot exchange rate in part (a) of this question. (c) Into this situation where the spot and exchange rates are equal, now suppose that, for whatever reason, short-term interest rates suddenly rise in the home country while they

do not change in foreign countries. In the context of covered interest arbitrage, what forces are set in motion and what will happen to the spot and forward exchange rates because of this change in domestic interest rates? Carefully explain. B.

Purpose of the Chapter

The purpose of this chapter is to introduce students to the characteristics and size of the many financial assets that are currently exchanged internationally. With the importance of international finance growing every day, it is important that students have a familiarity with the range of financial instruments available for transferring wealth across country borders and the nature of the investment decision that lies behind such movements.

Teaching Tips

A. Students today accept as conventional wisdom that globalization is a new phenomenon that will continue throughout their lifetimes. The opening vignette can be used to make the point that increased interdependence among nations has occurred in previous times and that various forces can slow down or sometimes even reverse the phenomenon. B. Since the first part of the chapter is primarily descriptive, much of it can be left to the students to read on their own. It is useful, however, to point out the various ways in which these financial assets can come about and their possible implications for the carrying out of economic policy. C. This material can be brought to life by discussing the pros and cons of having international financial instruments in one’s own portfolio, either directly or indirectly through mutual funds. A discussion of the impact of the increased internationalization of investing on the various stock and bond markets can also trigger student interest. D. If you plan to cover the latter part of the chapter on the various derivatives in any detail, we strongly encourage buttressing this introductory material with examples and problems from a text in international business/finance. E. If possible, invite an expert in international finance from a local bank or the finance department to give a guest lecture on this material. This would be especially useful for those students who might be considering investment banking as a career. V.

Answers to End-of-Chapter Questions and Problems

1. The growth in the eurodollar markets was the result of a number of factors. For example, on the supply side, the oil shock in the 1970s and the accompanying build up of petrodollars abroad was a key factor, as well as the sustained balance-of-payments deficits of the United States in the 1960s. In addition, European banks were able to offer relatively higher interest rates for eurodollar deposits because they did not face interest rate ceilings such as that produced by Regulation Q in the United States, and they were willing to offer a higher rate because eurodollar deposits were not subject to any legal reserve requirement and thus earned higher returns than other deposits. On the demand side, the tightening of the money supply in the United States in the 1960s made borrowing dollars in the United States more difficult for all, but especially for foreigners because of the foreign lending guidelines proposed by the Federal Reserve and the imposition of the interest equalization tax on loans made to foreigners. In addition, lending rates on eurodollars were less than lending rates in the United States. Consequently foreign demand for eurodollars increased. Finally, U.S. banks themselves contributed to the growth in demand for eurodollars as they attempted to obtain dollar funds from their overseas branches during the tight money period when borrowing rates on eurodollars were actually lower than borrowing rates at home.

Chapter 21 - International Financial Markets and Instruments: An Introduction

2. Since the interest rate in the United States is less than that in England, the pound should be at discount (the U.S. dollar at premium) such that, in financial equilibrium, the difference in the two rates is exactly offset by the difference between the spot and the forward and/or expected exchange rate, leaving the investor indifferent between the two markets. 3. One would expect the eurodollar deposit rate to be above 6½ percent and the lending rate to be below 8½ percent. Because the eurodollar deposits are not subject to the reserve requirements and other possible bank regulatory controls, including state and local taxes faced by domestic banks, eurodollar deposits potentially earn more and therefore eurobanks are willing to pay higher deposit rates and charge lower loan rates compared to similar loans in the United States. If local taxes on international financial activity were reduced, the respective deposit and lending rates would be expected to move more closely together. 4. Because eurodollar accounts are not subject to a reserve requirement or the 10 basis points deposit insurance costs, they should be willing to pay a deposit rate that is larger than 6½ percent by the equivalent costs of these two items. That is, they should be willing to pay a rate equal to (.065 + .001)/(1- .02) = .0673, or 6.73 percent. (See footnote 12 in the chapter.) 5. Bonds are initially issued for a specific face value, with a specific maturity date and a specific annual interest rate. The bond thus earns an amount each year equal to the stated interest rate times the face value (the coupon payment). With an increase in interest rates, bonds (whose rate of interest is now below the current market rate) will be less attractive to investors and they will attempt to sell them and move into investments paying a higher rate of return. Because the bonds can only be sold at a lower price, bond prices will fall until the fixed coupon payment (as a percentage of the new lower price) represents a higher rate of return equal to that currently on the market. This activity could well lead to the newspaper headline cited in the question. 6. The nominal rate of interest can never be negative because that would indicate that people were willing to pay someone to have use of their money, i.e., they want the nominal value or absolute size of their savings to decline over time, not increase. On the other hand, the real interest rate (the nominal rate minus the rate of inflation) can be negative if the rate of inflation exceeds the nominal interest rate. In this case, the nominal value of savings is increasing, but the purchasing power of those savings is declining because prices are rising at a faster rate than the rate at which savings are growing, i.e., the interest rate. If there are money markets in other countries that are paying a positive real rate of interest, then individuals should be attempting to move their funds out of negative real return investments in the home country to investments with the more attractive real rates abroad. In an integrated financial environment with no barriers to capital movements, funds would be shifted out of the country, which would place upward pressure on the nominal rate at home. Such pressure should continue until real interest rates are equalized. If negative real rates persist, this is a sign that there are barriers to capital movements and that the country is not well integrated into the world financial markets.

futures contract for more than $1 million, e.g., $10 million, one simply negotiates a contract containing 10 such units. If investors wish to hedge against interest rate changes for more than a three-month period, for example nine months, they would simply acquire a series of successive eurodollar interest rate futures contracts which would cover the nine months in question. This could be done for a nine-month period starting in December 2012 by acquiring a March 2013 futures contract, a June 2013 futures contract, and a September 2013 futures contract. When the March contract came to an end, it would be rolled over into the June contract. Similarly, when the June contract came to an end, it would be rolled over into the September contract. The individual in question would thus be hedged against changes in the interest rate for the ninemonth period ending on the September contract date. This type of collection of eurodollar interest rate futures contracts is referred to as a eurodollar strip. 8. A characteristic of any futures contract is that gains or losses of the contracting parties are settled on a daily basis, and not on the final maturity date. Thus, for example in a currency futures contract, if a particular currency begins to depreciate (move away from the contract rate) the party agreeing to supply (taking a short position) the other (appreciating) currency at the contract rate must make up any change in the difference between the current rate and the contract rate on a daily basis. When the contract comes due, the supplier will have paid enough into the account such that the holder of the contract will be able to acquire the needed foreign exchange from the market on the contract date by using a combination of funds at the contracted rate and the additional funds provided by the seller of the contract. Steady and large movements away from the contract rate can thus ultimately result in cash flow problems for the seller of the contract. Similar problems can occur in interest rate futures contracts as well, the principal difference being that the daily margin pertains to deviations of the market rate of interest from the contract rate (rather than deviations in the exchange rate.). 9. A eurodollar interest rate swap involves the exchange of interest rates by the two contracting parties for several periods in the future. This generally involves the exchange of a fixed rate by one party for a floating rate held by the other party, and is most often written in terms of LIBOR. This type of contract can benefit both parties in that a person holding a fixedrate loan cannot benefit from declines in the market rate of interest and thus might prefer to hold a variable-rate instrument. On the other hand, an individual with a flexible-rate loan might feel at risk because of potential increases in the interest rate and hence the cost of his loan. A swap thus enables the person who would prefer to take on more risk by switching from a fixed rate to a flexible rate to obtain the more preferred position and, at the same time, permits the holder of a floating-rate loan to reduce his interest rate exposure by obtaining a fixed rate without having to renegotiate the original loan. A “normal swap” involves the exchange of a fixed rate for a floating rate. A “basis swap” occurs when both sides are contracting a floating rate (a floating-floating swap). If the economic environment and or expectations should change, either or both contracting parties can contact a swaps trader and enter into a second swap arrangement. 10. In futures contracts, both the writer and the buyer of the contract can potentially lose, depending on what happens to the market interest rate.

Chapter 21 - International Financial Markets and Instruments: An Introduction

writer of the options contract bears all the risk associated with interest rate changes. This asymmetry is dealt with through the size of the up-front cost of the futures contract (the option price), which is paid by the purchaser of the options contract. The greater the risk, the higher the option price. 11. The growth in loan syndicates has fostered growth in international lending by reducing the credit risk to any one single lender, particularly in the case of very large loans to sovereign borrowers. In addition, syndication has resulted in a reduction in the time for processing loans and a decrease in the costs associated with international lending, and has facilitated the contracting of very large loans. In a loan participation syndicate, the principal or lead bank negotiates the loan instrument with the borrower and then enters into participation agreements with other banks (syndicates the loan). In this case the participating banks are not viewed as co-lenders. In the case of the direct loan syndicate, all the bank participants sign a common loan agreement and are legal co-lenders. 12. In this case, you would purchase a “call” at the strike price of 9250, since 10,000-9250 (equivalent to 1.000 - 0.925) reflects a 7.5 percent rate of interest. For this contract you would have to pay 54 basis points. Since each basis point is worth $25, a $1 million contract would cost (54)($25) or $1,350. A $6 million contract would thus cost a total of $8,100. VI.

Chapter 22 - The Monetary and Portfolio Balance Approaches to External Balance

III.

Purpose of Chapter

The purpose of this chapter is to consider the role played by money and asset relationships in establishing and maintaining equilibrium in the external sector. In particular, students should learn how money and asset markets influence and are influenced by the balance of payments and exchange rates. With this material in hand, the reader will be better able to understand why exchange rates change so frequently and sizably in situations where they are not pegged. IV.

Teaching Tips

A. From their study of Chapter 20 in particular, the students should now have grasped the ideas that exchange rates can change quickly and sizably and that such changes can have important effects. The opening paragraphs in this chapter reiterate these ideas and pave the way for exploration of the underlying causes and consequences of exchange rate changes. You should emphasize that this chapter and the next two are devoted to this exploration. B. In the discussion of the monetary approach, point out that a rise in income improves the balance of payments in this model (because of the resulting increase in the demand for money). This may seem peculiar to students who remember from the principles course that a rise in income in a Keynesian model worsens the current account because of induced imports. However, the situations are not really directly comparable, because the monetary approach is dealing not just with the current account but with the overall BOP (official reserve transactions balance). C. The point that, in the monetary approach, a fall in the interest rate leads to an improvement in the BOP (because the interest rate reduction increases money demand relative to money supply) needs to be stressed. Students (probably rightly so) will rebel against this, in that their intuition suggests that the lower interest rate will cause a financial capital outflow and a deterioration in the BOP. The students’ intuition is validated in the later discussion of the portfolio balance approach. D. The material on exchange rate overshooting will probably be difficult for many students to follow – if you can think of a better way to present it, by all means please do so. It may help to point out that the Dornbusch and Melvin models are very similar, with the only substantive difference being that Dornbusch uses the expected exchange rate and uncovered interest parity while Melvin uses the forward rate and covered interest parity. V.

Answers to End-of-Chapter Questions and Problems

1. The balance of payments will move toward surplus because the rise in income increases the demand for money and the money supply is unchanged. With excess demand for money, individuals attempt to build up their cash balances, causing a reduction in spending on goods and assets (including foreign goods and assets), a process that will move the BOP toward surplus. In the portfolio balance approach, the result of the rise in income will also be a movement toward surplus, but the role of bonds and the interest rate is more explicit. The increased demand for

Chapter 22 - The Monetary and Portfolio Balance Approaches to External Balance

money raises the interest rate, foreign bonds are sold in the portfolio adjustment process, and there is a capital “inflow” into the home country. 2. The statement is true, as is explained in the section early in the chapter that discusses the demand for money. 3. From expression [12] in the chapter on page 560, it can be seen that a rise in k in country A leads to a proportional fall in e (an appreciation of A's currency). If, other things equal, people wish to hold more money, there is an excess demand for money. This excess demand leads to attempts to build up cash balances, an incipient surplus in the balance of payments, and an appreciation of the home currency. 4. PPP is more likely to hold in a hyperinflationary period because the money supply is usually out of control. With continual excess supply of money and expectations of continuing price rises, money “turns over” rapidly, bidding up the price level and driving down the international value of the home currency. All other determinants of the exchange rate are swamped by the extremely rapid price changes, so the exchange rate moves proportionately with the price level. In more “normal” periods, other influences (such as in the current account) on the exchange rate besides prices will have an important role. 5. This is obviously an opinion question. Utilizing Dornbusch’s sample and test (as discussed in the Appendix), only the interest rate variables were of the correct sign and statistically significant. However, during much of the 1973-1979 period that he was examining, the world economy was in disarray because of the first OPEC oil shock of 1973-1974 and the ensuing dislocations. For longer periods with very rapid inflation (such as in the Frenkel test), the monetary approach performs well. It would seem that further testing is necessary. Nevertheless, a point in favor of the monetary approach even in Dornbusch’s test is that the interest rate variables tested well. This is noteworthy because, in view of intuition and the portfolio balance approach, one might expect opposite signs for those variables. 6. The issuance of foreign government bonds will affect the perceived risk (and hence RP) associated with investment in the foreign country. The relationship between RP and the exchange rate can be seen by utilizing equations [13] and [14] in the chapter (page 562). Noting that xa = [E(e) - e]/e and substituting appropriately in [13] results in id = if + [E(e) - e]/e - RP. With an increase in already-risky foreign bonds, the risk premium will increase, effectively lowering the rate of return abroad, making the right-hand side of the equation smaller than the left, and stimulating domestic residents to decrease their holdings of foreign assets. Decreased demand for the foreign currency to make these asset purchases will cause an appreciation of the home currency (a decrease in e), and possibly an increase in E(e), due to the fact that home investors buying assets abroad will now demand less home currency in the future as their investments mature. Barring any changes in the interest rates in both countries, these exchange rate changes will take place until the increase in xa exactly offsets the initial increase in RP. Of course, if the interest rates also change in response to the short-term capital flows, if should increase and id should decrease, thus reducing the degree of change in the exchange rate.

Chapter 22 - The Monetary and Portfolio Balance Approaches to External Balance

7. Following the framework used in Question #6 above, an increase in id will lead to an inflow of short-term capital into the home country. As investors acquire the domestic currency to make these investments, the demand for the home currency will increase and the exchange rate will appreciate (e gets smaller). This, of course, might be accompanied by an increase in E(e), a fall in id, an increase in if, and a decrease in RP. Should any of these occur, the degree to which e appreciates will be less. A monetarist would not come to the same conclusion. According to the monetarist approach, an increase in id will lead to a fall in the demand for money in the home country, causing the home country money supply to exceed home country money demand. In the open economy, this money market disequilibrium will lead to home country currency depreciation, not appreciation. 8. This statement can be defended using either the Dornbusch model or the Melvin model spelled out in the last section of the chapter. 9. With the huge volume of mobile short-term assets in existence, and with the huge amount of information available virtually immediately, actors in asset markets can respond quickly and sizably to any disequilibrium situation (such as a departure from uncovered or covered interest parity). Goods markets are slower in adjusting since the production process takes time and changes in it involve waiting to see if any change is truly a permanent change. Consumption and demand patterns also do not change rapidly because of inertia and because of less complete information than is available in financial markets. 10. The answer to this question is developed at the end of the chapter. The basic idea is that if E(e) is equal to efwd, then xa {= [E(e) - e]/e} is equal to (efwd - e)/e and there are no unexploited profit opportunities. The absence of such opportunities for profit in the market is the way that market efficiency is defined. 11. Students might respond to this question by indicating that the asset approach offers plausible explanations of instability in exchange rates and of overshooting, that it integrates financial markets with the exchange rate, that it reflects the reality of the large influence of interest rates and expectations on exchange rates, etc. On the other hand, the approach may underplay the role of changes in real factors in the economy on exchange rates and the balance of payments, particularly in countries (such as developing countries) where asset markets are thinly developed and/or financial capital is relatively immobile and subject to exchange control. Also, this approach to the exchange rate loses some relevance in a situation of relatively fixed rates, and many countries in the world have at least some element of “fixity” in their rates. Finally, the approach says little about the impact of exchange rate changes themselves on the economy, but it was not really designed to undertake that task.

1. Explain the implication for a country’s exchange rate in the monetary approach and in the portfolio balance approach of (a) an autonomous decline in the demand for money at each interest rate by the country’s citizens, and (b) a change in expectations by the country’s citizens such that less inflation is expected in the future. 2. Why do the monetary approach and the portfolio balance approach have different expected signs for the impact of a change in the domestic interest rate on the exchange rate? Explain carefully. 3.

Teaching Tips

A. It often appears that the prices of foreign goods do not change as expected with respect to changes in the exchange rate. It is useful to focus on the fact that this can be influenced both by market characteristics and by the nature of the foreign exchange rate regime that is in place. B. The characteristics of the foreign exchange market are critical to understanding the nature of the adjustment process. We have found that linking the foreign demand schedule for home goods and services to the supply schedule of foreign currency by numerical example is a useful way to demonstrate how an unstable foreign exchange market can result from inelastic demand for traded goods. A backward-sloping supply curve of foreign exchange is not necessarily an unlikely possibility in the short run. C. We do not feel that it is useful to expend too much effort on the Marshall-Lerner condition. Consequently, the derivation is in an appendix. The Marshall-Lerner condition is, however, a useful vehicle to drive home the basic idea that foreign exchange market stability properties are the consequence of both demand and supply considerations. Using estimates such as those found in Table 3, the Marshall-Lerner condition is useful for giving confidence to the likely existence of stable market equilibria, at least in the medium to long term. D. Given the continually-voiced interest in returning to a fixed exchange rate system, this is a good time to make the student aware of the different manner in which price adjustments take place under fixed rates as opposed to flexible rates. E. Make certain that students understand the link between gold flows or obligatory central bank interventions in the foreign exchange market and the domestic money supply under fixed rates. If students grasp this basic link at this point, it will make Chapter 25 containing analysis of economic policy under fixed exchange rates much easier to follow. V.

Answers to End-of-Chapter Questions and Problems

1. This is not valid. The existence of a downward-sloping supply curve of foreign exchange is not a sufficient condition for producing an unstable equilibrium. If the downward-sloping supply curve is steeper than the demand curve, the exchange market is stable. Only if the downward-sloping supply curve is flatter than the demand curve will the equilibrium position be an unstable one. 2. In the analysis of this chapter, it is necessary that the supply curve be downward-sloping in order for the equilibrium position to be unstable. However, if one were to get more exotic and specify that the demand curve could be upward-sloping, then an upward-sloping demand curve coupled with an upward-sloping supply curve that was steeper than the demand curve would generate an unstable equilibrium position. However, it is best to forget about this possibility in this class! 3.

According to the Marshall-Lerner condition, the current account balance will improve

Chapter 23 - Price Adjustments and Balance-of-Payments Disequilibrium

because of currency depreciation if the sum of the absolute values of the elasticities of demand for imports and exports is greater than 1.0. In this problem the elasticity of demand for imports is equal to {(790 - 810)/[(790 + 810)/2]}/0.10 = - 0.25. The elasticity of demand for exports is equal to {(1,025 - 975)/[(1,025 + 975)/2]}/(-0.10) = - 0.50. The sum of the absolute values of these two elasticities is thus 0.75, which is strictly less than 1.0. One would therefore conclude that a depreciation of the home currency would cause the current account balance to worsen. 4. This could be explained in terms of a J-curve phenomenon. If the short-run elasticities of supply and demand for traded goods are sufficiently inelastic (producing a backward-bending supply curve of foreign exchange and a very steep demand curve such that the Marshall-Lerner condition is not met in the short run), then the foreign exchange market in the short run is unstable and an increase in the exchange rate (depreciation of the dollar) will lead to a worsening in the balance of trade. Of course, income growth in the United States and stagnation in Japan would have strengthened this result. 5. This question calls for the students to examine their own behavior. If the short-run response is different than the long-run response (e.g., more inelastic), and if enough people behave similarly so that the market elasticities are different in the short run than in the long run, the J-curve phenomenon can result. In the J-curve phenomenon, a depreciation of the home currency leads to a worsening of the current account in the short run but to an improvement in the long run as elasticities become greater. 6. If the Chinese are keeping their currency undervalued (below the market equilibrium price), it would decrease their own demand for foreign goods and services and hence their import outlays, as well as stimulate foreign purchases of Chinese goods and services and hence Chinese export revenues. There would thus be a smaller current account deficit, a current account surplus, or a larger current account surplus than would otherwise occur. This assumes that the Marshall-Lerner condition is met since the depreciation of the renminbi yuan leads to an improvement in the current account. 7. (a) The dollar/pound exchange rate is $40/£20 or $2/£1. Given the transactions cost of $1/oz., the gold export point is thus $41/£20 = $2.05/£, and the gold import point is $39/£20 = $1.95/£. (b) The peso/pound exchange rate is 60 pesos/£20 or 3 pesos/£1. Given the transactions cost of $1/oz. or 1.5 pesos/oz. (since 60 pesos = $40), the gold export point is 61.5 pesos/£20 = 3.075 pesos/£1, and the gold import point is 58.5 pesos/£20 = 2.925 pesos/£1. (c) The peso/dollar exchange rate is 60 pesos/$40 = 1.5 pesos/$1. Given the transactions cost of $1/oz. (1.5 pesos/oz.), the gold export point is thus 61.5 pesos/$40 = 1.5375 pesos/$1, and the gold import point is 58.5 pesos/$40 = 1.4625 pesos/$1. 8. The term “pass-through” refers to the degree to which changes in the exchange rate are realized in changes in the prices of goods. If the dollar depreciates by 10 percent against the Japanese yen, then the prices of Japanese goods to U.S. consumers should rise by 10 percent if 23-2 © 2014 by McGraw-Hill Education.

the entire impact of the exchange rate change is passed on in the form of increases in the prices of Japanese goods in the United States (a “pass-through” of 100 percent). Japanese exporters can offset the impact of the appreciating yen (depreciating dollar) by reducing their domestic prices, thus leading to an increase in the price of Japanese goods in the United States that is less than the depreciation of the dollar, i.e., reducing the degree of “pass-through.” VI.

Under either a gold standard or a pegged-rate system, what changes in the money supply are necessary in order for effective adjustment to take place? Why are these changes necessary? 6. Is the Marshall-Lerner condition of any relevance for the successful operation of the gold standard adjustment mechanism? Explain. 7. Assume a two-country world containing country A (whose currency is the dollar) and country B (whose currency is the peso). In this context, and using relevant graphs, explain how a depreciation of the dollar against the peso (for example, a 10% depreciation) conceptually affects the quantity of A’s exports to B and the quantity of A’s imports from B. (You can use either dollars or pesos on the vertical axes of your graphs. Also, assume that “pass-through” is complete.) Then carefully explain why economists say that such a depreciation could actually worsen the trade balance (or current account balance) of country A and indicate the MarshallLerner condition.

Teaching Tips

A. The opening vignette can be used to make sure that the students realize that the foreign trade sector of the economy is not something separate from the rest of the economy – rather, it is intricately interdependent with developments in the “internal” sector. B. The basic Keynesian model developed should be familiar to your students because most principles books now include the foreign sector in the model (although sometimes only in appendixes to chapters). Therefore, we recommend that you not devote too much class time to the purely mechanistic material in this model. C. Note that we make imports dependent on total income and not on disposable income. If you choose to make them dependent upon disposable income, you will end up with a different formula for the autonomous spending multiplier, as we indicate in expression [23] in Appendix A. D. Some international economics texts call the open-economy multiplier the “foreign trade multiplier.” We recommend that you not use that term, however, since we think that it is misleading – the multiplier does not apply only to autonomous changes in the foreign trade sector of the economy. E. Remind the students that prices are fixed in this chapter (except for reference to exchange rate changes). Price changes are considered later in the aggregate demand-aggregate supply material in Chapter 27. However, you may want to discuss possible effects here in a general way, although it is much easier to do in the IS/LM/BP framework which is presented in the following chapter. V.

Answers to End-of-Chapter Questions and Problems

1. An autonomous increase in saving at each income level is equivalent to an autonomous decrease in consumption at each income level. The autonomous decrease in consumption will decrease equilibrium national income by the autonomous consumption change times the openeconomy multiplier, 1/(1 - MPC + MPM), or if taxes depend on income, 1/(1 - MPC + MPCt + MPM). (Note that this assumes that the first round reduction in C impacts only on domestic goods; otherwise the numerator would be 1 - MPM.) 2.

(a) Y = C + I + G + (X - M) Y = 50 + 0.85Yd + 150 + 300 + 80 - (10 + 0.05Y) Y = 50 + 0.85(Y - 400) + 150 + 300 + 80 - (10 + 0.05Y) Y = 0.85Y - 0.05Y + 230 = 0.80Y + 230 Y = (1/0.2)(230) Y = 1,150

Therefore the equilibrium level of income is 1,150. (b) At the equilibrium level of income, because X = 80 and M = 10 + 0.05(1,150) = 67.5, there is a current account surplus of 12.5.

Chapter 24 - National Income and the Current Account

(c) 1/[(1 – MPC) + MPM] = 1/[(1 - 0.85) + 0.05] = 1/(0.15 + 0.05) = 5. 3. Y would have to rise by 250, because this increase in Y would increase M by 12.5 with an MPM of 0.05. Because the multiplier is 5, autonomous investment would have to rise by 50 (= 250/5) in order to generate this increase in Y. 4. If a country has a current account surplus (X > M), then a reworking of the national income expression S + M + T = I + X + G to S + (T - G) - I = (X - M) indicates that saving (private plus government) exceeds investment by the amount of the current account surplus. In effect, the excess of saving over investment has been lent abroad to permit foreigners to purchase more of the home country’s exports than the home country buys in imports from foreign countries. Alternatively, the positive net exports generate, with no change in investment, a rise in income that yields saving (private plus government) greater than investment. 5. If Germany pursues a policy that results in a lower rate of growth, then its growth in demand for goods from its trading partners will also slow down. A slower rate of growth of German imports from its trading partners can not only contribute to balance-of-trade issues, but can also reduce the growth rate in these trading partners. Trading partners that were trying to reduce a trade deficit with Germany and/or attempting to grow at a faster rate than would be consistent with Germany’s performance would more than likely be frustrated with German economic policy. 6. Expansionary fiscal policy in Japan would lead to an expansion of Japanese income and thus increased imports, some of which would come from the United States. This expansion of Japanese imports from the United States would, other things equal, reduce the U.S. trade deficit with Japan. However, the increased U.S. exports would provide a stimulus to U.S. income, and this U.S. income growth would stimulate greater U.S. imports from Japan. This “foreign repercussion” would reduce the degree to which the growth in Japanese income would work toward eliminating Japan’s surplus with the United States. The overall result would be a reduction in the U.S. deficit with Japan, but not to the degree expected if foreign repercussions were not taken into account. 7. (a) Since E = Y in equilibrium, then Y = C + I + G + X - M. Substituting the equations and/or exogenous values for the various expenditure items into the income identity produces Y = 120 + .075(Y - 40 - 0.20Y) + 230 + 560 + 350 - 30 - 0.10Y Y - 0.75Y + 0.15Y + 0.10Y = 120 - 30 + 230 + 560 + 350 - 30 = 1,200 0.5 Y = 1,200 Y = 2,400 (b) T = 40 + 0.20Y T = 40 + 0.20(2,400) = 520 The government surplus (deficit) = T - G = 520 - 560 = - 40. Therefore the government is running a deficit of 40 at equilibrium.

(c) M = 30 + 0.10Y = 30 + 0.10(2,400) = 270 Because the trade balance equals exports minus imports, it is equal to 350 - 270 = 80. The country is thus running a trade surplus of 80 at equilibrium. 8.

Essay Questions

1. If a country has a current account deficit, this is often referred to as a situation where the country is “spending beyond its means.” What does this phrase mean in terms of the simple Keynesian model? Does the existence of the current account deficit imply that the country as a whole is a dissaver (i.e., that saving is actually negative)? Why or why not? 2. Suppose that autonomous consumption increases but that, unlike the situation in the simple Keynesian model of this chapter, some of this autonomous consumption increase is spent on imports (say an amount equal to MPM times the autonomous consumption increase) in the “first round” of the multiplier process.

Chapter 25 - Economic Policy in the Open Economy under Fixed Exchange Rates

III.

Purpose of Chapter

The purpose of the chapter is to develop the IS/LM/BP analysis and then to show how domestic macroeconomic policy influences the open economy under a system of fixed exchange rates. The policy material focuses on the impacts of monetary policy, fiscal policy, and expenditure-switching policies under different degrees of international capital mobility. IV.

Teaching Tips

A. In recent years various news sources have emphasized that the Chinese renminbi yuan has been pegged to the U.S. dollar since 1994 and that the Chinese trade surplus with the United States has grown steadily over this time. This has led to considerable pressure on the Chinese to revalue (appreciate) their currency to reduce this trade imbalance. (In fact, since 2005, the Chinese have allowed the yuan to appreciate somewhat against the dollar.) This chapter’s opening vignette points out that there are indeed different opinions on the need or desirability of this policy action by China and that such action can have far-reaching effects. This case can be used to generate interest in the policy implications of a fixed exchange rate in the open economy. B. The discussion of the Mundell model in the first section is essentially an introduction to macro policy in the open economy and can be left to a considerable degree to the students to read on their own. It is, however, useful to emphasize the policy degrees-of-freedom issue and the reason why monetary policy is usually assigned to the external target (which is handled nicely in the familiar Mundell-Fleming diagram). C. The IS and LM curves may be familiar to some of your students but probably not to all of them. The standard four-quadrant derivation of these curves is not done in the chapter, but you may want to do so to make the material clearer. D. It is a good idea to discuss the BP curve thoroughly, making certain that the students recognize the factors that shift the curve and the nature of the balance-of-payments disequilibrium if the intersection of the IS and LM curves does not occur on the BP curve. It is also important to make sure that the students recognize how the slope of the curve depends on the degree of international short-term capital mobility. E. If you are constrained by time, we suggest focusing primarily on the imperfectly mobile capital case where BP is flatter than LM, since it characterizes the U.S. situation. Given the number of countries with fixed exchange rates and strict capital controls, the perfectly immobile case is also of interest to students. F. A critical message of this chapter is that the effectiveness of a particular policy instrument is dependent upon the nature of the exchange rate system and the degree of capital mobility. The analysis, among other things, can help to explain why the U.S. economy relied more on fiscal policy under the Bretton Woods system than in the current flexible-rate system.

G. You should make the point that sterilization operations by the central bank under a fixedrate system can at best delay the responses discussed in this chapter. V.

Answers to End-of-Chapter Questions and Problems

1. The system must come to rest at the combination of interest rate and income where all three sectors are simultaneously in equilibrium. If the domestic equilibrium (intersection of IS and LM) is above the BP curve, under fixed rates there will be a surplus in the balance of payments, a resulting inflow of foreign exchange, and a consequent expansion of the money supply. As this occurs, the LM curve will shift to the right (downward), lowering the interest rate and expanding domestic investment, income, and imports. This shift will continue to take place until the combination of the interest rate and income causes all sectors to be in equilibrium at the same time. Similarly, a combination of the interest rate and domestic income that lies below the BP curve will lead to a balance-of-payments deficit, an outflow of foreign currency, and a consequent contraction in the money supply and leftward shift in the LM curve. This will cause the interest rate to rise and income to fall until there is again simultaneous equilibrium in all three sectors. 2. Monetary policy is ineffective in this scenario because changes in the money supply trigger changes in the domestic rate of interest as the LM curve shifts along the IS curve. With a change in the interest rate, short-term capital movements take place that produce either a surplus or deficit in the balance of payments. As the central bank intervenes to maintain the pegged value of the currency (or the appropriate gold flows take place under a gold standard), there is a contrary change in the money supply exactly equal to the initial effect of the monetary action. The end result is a return to the initial equilibrium that existed prior to the monetary action. 3. With an increase in the money supply, the domestic rate of interest temporarily falls below the international rate of interest as the LM curve moves rightward along the IS curve. In the case of perfect capital mobility, this immediately causes domestic investors to shift shortterm capital holdings from domestic assets to foreign assets to maximize their financial returns. As they acquire the desired foreign exchange (with domestic currency) from the central bank, there is a reduction of the home country’s international reserves and a decline in the money supply. This will continue until the economy is once again back in the initial equilibrium position. 4. In the case of perfectly immobile capital, the level of income is determined by the balance-of-payments constraint, i.e., the vertical BP curve. Income can only be increased by shifting the BP curve to the right, since attempts to increase income with either domestic monetary or fiscal policy create a balance-of-payments deficit that leads to a decrease in the money supply and offsets the initial expansionary effort. Thus, income will only grow as there is an inflow of foreign currency due to increased exports, foreign investment, or foreign aid that shifts the BP to the right and thereby permits the attainment of a higher level of income.

5. Fiscal policy is least effective when capital is perfectly immobile (see Question #4). It is the most effective when capital is perfectly mobile, since in this instance there is no accompanying increase in the interest rate and hence no crowding out of domestic investment. 6. A devaluation of the currency leads to an expansion of exports and a contraction of imports, which shifts the IS curve to the right and shifts the BP curve down (to the right). A surplus in the balance of payments results, which leads to an increase in the money supply as the central bank acts to maintain the new exchange rate. The increase in the money supply takes place until there is an equilibrium of the new IS, LM, and BP curves at a new, higher level of income. Devaluation is effective under perfectly immobile capital since it leads to a net increase in foreign exchange, thus allowing the economy to function at a higher level of income (i.e., it has the effect of shifting the vertical BP curve to the right). 7. Because capital is nearly, if not perfectly mobile between states in the United States, the appropriate BP curve would essentially be horizontal at the U.S. rate of interest. 8. Because, under a fixed exchange rate system, the central bank stands ready to support the currency at its pegged rate, the country must maintain sufficient foreign exchange reserves to meet any balance-of-payments deficits that occur at the stated rate. Because there may be situations of considerable excess demand for foreign exchange at the pegged rate and/or the fixed exchange rate may over time become structurally incorrect given other targets in the country, sizable foreign exchange reserves are necessary if the country is not to be constrained by the external balance requirement, e.g., by a reduction in the money supply and hence income. Countries that, for whatever reason, find themselves with persistent BOP deficits must maintain high levels of foreign exchange reserves if they wish to postpone the automatic adjustment that leads to a reduction in income. 9. Under a fixed exchange rate regime, expansionary fiscal policy would cause the IS curve to shift to the right, leading to an increase in the Japanese interest rate and income. Since the BP curve is flatter than the LM curve, the new IS-LM intersection will lie above the BP curve. In other words, for the new level of income, the interest rate is higher than that which is necessary to balance the balance of payments, and a surplus in the Japanese BOP occurs. (The Japanese current account has worsened, but short-term capital inflows have improved the capital/financial account by more than the current account deterioration.) The BOP surplus causes an expansion of the money supply as the Japanese central bank purchases the excess foreign exchange, and the LM curve shifts to the right until all three curves are again in simultaneous equilibrium. The expansionary fiscal policy is thus complemented by an expansion in the money supply, leading to an even greater expansion of income. The higher level of income will, of course, generate an increase in imports into Japan, some of which would come from the United States. Thus, other things equal, there would be a reduction in the U.S. trade deficit with Japan. If the BP curve were steeper than the LM curve, the initial fiscal expansion would still worsen the current account, but there would be a Japanese BOP deficit at the intersection of the original LM curve with the new IS curve. (The increased net capital inflows would be insufficient to offset the worsening of the current account.) Hence, the Japanese money supply 25-2 © 2014 by McGraw-Hill Education.

Chapter 25 - Economic Policy in the Open Economy under Fixed Exchange Rates

would contract. The end result will still be a higher level of Japanese income and more imports into Japan than before the fiscal action, but the reduction in the U.S. current account deficit would be less than when the BP curve was flatter than the LM curve. 10. In this scenario, it is difficult if not impossible for a country to influence in any significant way the domestic interest rate and thereby to have much divergence from the international rate. Since the BP curve in this case would be nearly horizontal (slightly upwardsloping) and presumably flatter than the LM curve, any attempt to stimulate growth by increasing the money supply and lowering interest rates will simply result in an outward flow of short-term capital (reducing the domestic money supply) until the domestic interest rate again approximates the international (EU) rate. Similarly, an attempt to reduce inflationary pressures by reducing the money supply and placing upward pressure on the domestic interest rate will quickly lead to an inflow of capital and an increase in the money supply until the interest rate again approximates the international rate. Growth and/or inflation targets thus must be pursued through the use of fiscal policy in this economic environment. Fiscal policy can alter real GDP, but not through any interest-rate target mechanism. 11. This is one of the cases in the phenomenon known as the “impossible trinity.” If the country wishes to maintain a fixed exchange rate and it also permits free flows of short-term capital into and out of the country, then monetary policy cannot be independent because effective control of the money supply is lost. For example, contractionary monetary policy would raise interest rates and lead to a short-term capital inflow that would put pressure on the home currency towards appreciation. Under fixed rates, the central bank would have to purchase the excess supply of foreign currency with home currency, which would increase the domestic money supply and offset the initial contractionary policy action. Clearly, expansionary monetary policy would set the reverse forces into motion, and the resulting short-term capital outflows would require the central bank to purchase home currency to prevent depreciation; this action would reduce the money supply back to its original level. In either of these cases, if the central bank did not intervene, the exchange rate would change and there would be monetary independence but no longer a fixed exchange rate. Hence, in order to be able to influence the money supply as well as to maintain fixity in the exchange rate, the country has to institute controls on short-term capital flows so that those flows will not put the upward and downward pressures on the exchange rate.

Teaching Tips

A. The opening paragraph sketches some choices that have been made by several different countries regarding their exchange rate regimes. Students will be inclined to think that such choices affect principally the foreign sector, with some spillovers to the domestic economy. You should stress that the choice has much wider implications, however, because it conditions the overall relative effectiveness of different macroeconomic policy instruments for guiding the economy toward the country’s preferred goals. B. One of the keys to understanding the analysis in this chapter is grasping how changes in the exchange rate, along with other variables, shift the BP curve back and forth. It is important to review this (again) before you get into the content of the chapter. C. The various assumptions regarding capital mobility are more critical under flexible rates than under fixed rates. This point can be driven home in the case of fiscal policy actions that have less and less impact on income as capital becomes more and more mobile. Discuss the implications of this in today’s world where financial markets are becoming increasingly interdependent and capital more and more mobile among the major financial centers of the world. D. We find it useful to emphasize strongly the effects of exogenous international shocks such as relative price changes, foreign interest rate changes, etc., on the domestic economy. This makes the students aware of the difficulty of carrying out economic policy when one has to deal not only with domestic factors but also with events taking place in other countries. E. As part of the comparative statics exercises, examine the impact of a change in domestic prices on equilibrium income levels. Since this is the manner in which an aggregate demand curve is derived in Chapter 27, it is a good bridging technique between the content of the IS-LM analysis and the aggregate supply/demand model and gives the student some anticipation of what is coming.

Answers to End-of-Chapter Questions and Problems

1. If the intersection of the IS and LM curves is at a point below the BP curve, there will be an incipient BOP deficit and depreciation of the home currency. Assuming that the MarshallLerner conditions are met, as the currency depreciates exports expand and imports contract, leading to a downward shift in the BP curve and to a rightward shift in the IS curve. These adjustments continue until there again is equilibrium on all three curves at some point on the unchanged LM curve. 2. The position of the BP curve is influenced by any factor other than domestic income and the interest rate that impacts upon the capital/financial and current accounts in the balance of payments. Therefore, foreign and domestic prices, expected prices, foreign and domestic tastes and preferences for traded goods, foreign income, and foreign and domestic trade policy are examples of factors that influence the current account and hence the BP curve. The financial 26-2 © 2014 by McGraw-Hill Education. This is proprietary material solely for authorized instructor use. Not authorized for sale or distribution in any manner.

Chapter 26 - Economic Policy in the Open Economy under Flexible Exchange Rates

account is influenced by such phenomena as the foreign interest rate, expected exchange rates, domestic and foreign rates of return on investment, foreign and domestic tax policy, foreign and domestic financial reforms, and relative economic/political stability. 3. Fiscal policy is completely ineffective when capital is perfectly mobile. This result occurs because the upward pressure on the domestic interest rate generated by expansionary fiscal action (rightward shift in the IS curve) generates, because of large-scale capital inflows, an incipient BOP surplus and an appreciation of the currency. The appreciation leads to an increase in imports and a decrease in exports (leftward shift in the IS curve). The appreciation and trade (price) adjustment process will continue until the initial effect of the expansionary fiscal policy is exactly offset and any upward pressure on the interest rate is removed. 4. Under a fixed-rate system, the country is committed to maintain the exchange rate either through unobstructed gold movements or by appropriately buying or selling foreign exchange. As a result, the central bank loses control of the money supply as an instrument for meeting targets other than external balance. Even if the automatic money supply changes are sterilized by policy action, this can only be a temporary stopgap. Under a flexible-rate system, external balance is maintained automatically through changes in the exchange rate, assuming that the Marshall-Lerner condition holds. There is thus no constraint on the central bank regarding the size of the money supply necessary for maintaining relative currency value. In fact, as explained in the answer to Question #5 immediately below, the foreign sector relative price adjustments that accompany monetary policy actions tend to reinforce the intent of the policy. 5. Under a flexible-rate system, expansionary monetary policy puts downward pressure on the interest rate which, in turn, puts downward pressure on the value of the home currency as investors shift out of financial investments denominated in the home currency. Depreciation of the currency expands exports and reduces imports. There is thus a two-fold expansionary effect on the economy, a stimulus for greater real investment at lower interest rates and a greater demand for domestic goods and services as exports rise and imports fall. The price adjustment process thus complements the monetary action, whereas under fixed rates the adjustment process leads to a loss in reserves and a contraction in the money supply that offset the initial policy action. 6. Expansionary monetary policy will increase exports and decrease imports as downward pressure is put on the interest rate and, subsequently, the value of the home currency (assuming that the Marshall-Lerner conditions are met). Thus, one would expect those associated with export industries and import-competing industries to favor such a policy. On the other hand, those who consume relatively more imports and merchants involved in the retailing of imports would not favor such a policy. 7. Without additional information the precise impact of expansionary fiscal policy on the exchange rate is ambiguous because it depends on the interest-responsiveness of short-term capital internationally compared to the interest-responsiveness of the domestic money market (i.e., is the BP curve flatter or steeper than the LM curve?). In the case where the BP curve is 26-2 © 2014 by McGraw-Hill Education. This is proprietary material solely for authorized instructor use. Not authorized for sale or distribution in any manner.

Chapter 26 - Economic Policy in the Open Economy under Flexible Exchange Rates

flatter than the LM curve (relatively greater responsiveness internationally), there will be an appreciation of the home currency. This will offset at least some of the initial stimulus to income provided by the expansionary fiscal policy. In the case where the BP curve is steeper than the LM curve (relatively less responsiveness internationally), expansionary fiscal policy will lead to a depreciation of the home currency, and there will be additional income expansion beyond that provided by the initial expansionary fiscal policy. 8. If there is a rise in the expected appreciation of the foreign currency, there will be an incentive for investors to shift toward foreign currency-denominated financial assets. Thus, for every level of income, it will now take a higher domestic interest rate to balance the balance of payments, i.e., the BP curve will shift upward (to the left), and there will now be an incipient BOP deficit. The domestic currency will thus begin to depreciate (BP curve now begins shifting downward or to the right), stimulating exports and reducing imports. Assuming a normal price adjustment to the changing exchange rate (the Marshall-Lerner conditions are met), the current account balance improves and stimulates greater income and interest rates (i.e., the IS curve shifts to the right along the fixed LM curve). The BP curve continues to shift downward and the IS curve rightward until a new three-way intersection of IS, LM, and BP occurs. Income and the interest rate will both be higher than original and most likely so will the interest rate. (See the discussion following Figure 8 regarding the interest rate change.) 9. Under a flexible-rate system, the foreign price increases in petroleum and food would stimulate U.S. exports and reduce U.S. imports, leading to upward pressure on income and interest rates and an appreciation of the currency. The stronger dollar offsets, at least in part, the foreign price increases and the economy settles back close to the original equilibrium level. (See the last part of the chapter for a discussion of foreign price shocks using the IS/LM/BP model.) In contrast, under fixed exchange rates the improved trade balance leads to upward pressure on income and interest rates, which results in an inflow of short-term capital and, consequently, an increase in the money supply. This money supply increase stimulates an even greater increase in income and, quite likely, an increase in domestic prices. Under fixed rates, then, foreign price increases are passed on to the domestic economy whereas, under flexible rates, the foreign price increases are filtered out by increases in the exchange rate. 10. With the increase in interest rates in the EU, there will be an increase in demand for foreign exchange (e.g., the euro or the British pound) to invest abroad in order to take advantage of the higher earning potential (i.e., the BP curve will shift up, indicating that it will now take a higher domestic interest rate at every level of income to balance the balance of payments). The increased demand for foreign exchange will cause the dollar to depreciate in the spot market. The depreciation of the dollar will stimulate U.S. exports and reduce U.S. imports, which will put upward pressure on income and interest rates (i.e., the IS curve will shift to the right). Thus, the statement is correct. (See Figure 8 for a graphical explanation.) In addition, if the higher foreign interest rate reduces the home demand for money (via a portfolio balance effect), the LM curve will shift to the right, exerting even more upward pressure on income.

Essay Questions

1. Under a flexible exchange rate system, changes in the foreign rate of interest will affect both the financial markets and the real sector. Explain why this comes about using the IS/LM/BP model. What influence, if any, does the degree of international capital mobility have on the results? 2. If capital is imperfectly mobile (with BP flatter than LM), explain why governments find fiscal policy less effective under flexible rates compared to fixed rates. Is fiscal policy ever completely ineffective? If so, under what conditions? If not, why not? 3. Under flexible exchange rates, expansionary fiscal policy is less likely to lead to crowding out of investment and more likely to penalize the foreign sector than under fixed rates. Agree? Disagree? Explain. 4. It appears that the world is becoming more financially interdependent. How might you incorporate this change, if necessary, in the IS/LM/BP model? What are the implications of this change for macro policy in general and fiscal policy in particular? 5. The movement to more flexible exchange rates has made it necessary to more fully coordinate the use of monetary and fiscal policy. Explain why this is so, using the IS/LM/BP model, an income target, and an interest rate target. 6. Explain, using the IS/LM/BP model, how an increase in foreign interest rates can lead to an increase in domestic interest rates. 7. Explain, in the IS/LM/BP framework with flexible exchange rates, the impact of an autonomous increase in foreign demand for a country’s exports upon the country’s national income, money supply, and exchange rate. If there is no impact on a variable, explain why. B.

Purpose of Chapter

The purpose of the chapter is to examine the manner in which trade and international payments influence the macroeconomy when prices are flexible. Special attention is given to the implications of price flexibility for policy actions and for macroeconomic response to external shocks. IV.

Teaching Tips

A. Changes in international capital flows and trade flows exert pressure not only on income and employment but also upon prices. The less adaptable the economy is to changing economic conditions, the greater the price responses and adjustment costs for the economy. The severity of these problems is clearly evident in the adjustment difficulties experienced by Argentina (and some least-developed countries) described in the opening vignette. Discussing this experience with the class can help students appreciate these problems and see the need to incorporate price movements into policy analysis. B. We have attempted to provide a more rigorous background in aggregate demand and supply than is found in many international economics texts at this level. For those who have had a course in intermediate macro, the early part of the chapter provides a brief review of the basic ideas. For those who have never had such a course, this material will be more demanding. Because the class is likely to be diverse in background, you might find it useful to provide extra help sessions for those for whom the material is new. C. It is useful to emphasize that the principal difference in deriving the aggregate demand curve in the open economy rather than in the closed economy stems from the fact that the changing price level now also affects both the IS curve and the BP curve in addition to the LM curve. That is, there are now real effects of changes in prices, and these effects on exports, imports, and international capital flows involve shifts in IS and BP. D. The key to students grasping the AD framework is for them to realize that any factor that leads to an increase (decrease) in equilibrium income in the IS/LM/BP framework will lead to a rightward (leftward) shift in the AD curve. E. The AD/AS model provides a useful framework for contrasting the difference between policies that affect primarily demand and those which in addition influence the position of the long-run AS curve. For example, if restricting imports (expanding aggregate demand) is not to be solely inflationary in the long run, it must be accompanied by improved productivity, i.e., a rightward shift of the long-run AS curve.

Chapter 27 - Prices and Output in the Open Economy: Aggregate Supply and Demand

F. We have found that students are very interested in problems such as foreign price shocks that affect both the AD and the AS curves as, for example, in the case of petroleum price changes. G. Although we have not focused on the issue directly in this chapter, this is a useful place to emphasize the intertemporal aspects of policy. The student should not lose sight of the factors that contribute to long-run growth and shift the long-run supply curve to the right, and how these factors are affected by exogenous shocks as well as by domestic policies. V.

Answers to End-of-Chapter Questions and Problems

1. The natural level of employment is the level of employment at which the demand for labor equals the supply of labor and actual prices and real wages equal expected prices and real wages. This need not, of course, correspond to some society-defined level of full employment. The long-run supply curve is vertical at this point since by definition, the long-run period is sufficiently long for labor to adjust its wage demands to price changes such that the same amount of labor, and hence output, is supplied at the constant equilibrium real wage. 2. The short-run aggregate supply curve indicates the change in output produced because of a change in the price level, but with no change in the expected real wage. As indicated in the answer to Question #1 above, the long run is a period that is sufficiently long to allow workers to adjust their nominal wage demands in response to changes in prices so as to maintain a constant real wage. The long-run and short-run supply curves are both vertical in the case where rational expectations holds and are in fact the same curve. In this case, workers make full use of all information available, anticipate the price changes resulting from policy actions, and raise their wages at the same time as prices rise. If an unanticipated price change occurs, then the AS curve in the short run is temporarily not vertical. 3. The aggregate supply curves are shifted by underlying factors such as changes in technology, scale economies, changes in the level of capital stock, improved management techniques, and improved marketing arrangements. An increase in international transactions and increased contact with other countries could certainly lead to shifts in the supply curves due to technology transfers, adoption of foreign management approaches, more efficient use of resources due to scale effects associated with larger world markets, increases in capital stock associated with foreign real investment, etc. If increased international transactions also mean greater vulnerability to exchange rate changes, these changes would affect aggregate supply curves through their impacts on imported inputs. 4. Other things equal, the restrictive monetary policy in Germany would push German interest rates higher and stimulate an inflow into Germany of foreign short-term financial capital. In terms of the IS/LM/BP apparatus, such a policy would shift the U.S. BP curve upward (to the left). Without a monetary policy response on the part of the Federal Reserve leading to an offsetting change in domestic interest rates and income in the United States, Germany’s restrictive monetary policy would result in an incipient U.S. balance-of-payments deficit (under flexible exchange rates) and a depreciation of the U.S. dollar. With currency depreciation, U.S. 27-3 © 2014 by McGraw-Hill Education. This is proprietary material solely for authorized instructor use. Not authorized for sale or distribution in any manner.

exports to Germany increase and U.S. imports from Germany decrease. These foreign sector effects stimulate U.S. aggregate demand (shift the AD curve to the right) and put upward pressure on U.S. prices and income. However, given enough time for wages to adjust, the shortrun supply curve will shift up (to the left) and will return the U.S. economy to the “natural” level of income and employment, but now at a higher price level. 5. If imported inputs are important, the appreciation of the currency would have the effect of reducing the price of those imported inputs and hence reducing costs of production. This could lead to a rightward shift of both the long-run and the short-run aggregate supply curves, just as a sudden increase in the price of an important imported input led to a leftward shift in the aggregate supply curves in Figure 13 of the chapter. 6. If discretionary policy is to have more than a short-run impact on income and employment, it must result in changes in one or more of the structural factors that underlie the long-run aggregate supply curve. It must lead to changes in factors such as the capital stock, entrepreneurship, management techniques, scale effects, changes in technology, quality of the labor force, etc. 7. Expansionary monetary policy will increase aggregate demand, giving an even greater boost to prices. The stagflation has resulted from a leftward shift in the aggregate supply curves, and increasing demand alone will not solve the problem. Policies must be pursued to improve the supply situation through better technology, increased capital stock, improved education, etc. Income and employment will only increase in any permanent sense if there is an improvement in aggregate supply conditions. 8. If the home country’s currency is expected to depreciate, other things equal, it would lead to an increased demand for foreign currency. Under a flexible-rate system, this causes a depreciation of the home currency. As the currency depreciates, exports will increase and imports will decrease, leading to an increase in aggregate demand. If the country uses imported inputs, costs of production will also rise and both the short-run and long-run aggregate supply curves will shift to the left. The end result is an increase in the domestic price level and a reduction in the equilibrium level of income (output) in both the short run and long run. In addition, the natural level of employment falls. 9. Under the flexible exchange rate scenario of Figure 10, expansionary monetary policy would have the impact of shifting the aggregate demand curve to the right, leading to an expansion of income and accompanying increases in prices. With the appropriate level of money expansion, the economy could return to the natural level of income and employment. While this is desirable from the standpoint of employment, inflation would also occur. Were the government to do nothing and wages were flexible in a downward direction, with sufficient time, wages should fall and the short run aggregate supply curve would shift to the right until the natural level of income is attained at a lower price level. Which strategy is preferable depends on the country’s preferences with regard to reduced unemployment/inflation versus a longer period of unemployment with eventual lower price levels. If there are longer-run supply effects on the level of capital stock because of the continually-low interest rate, then the price level 27-2 © 2014 by McGraw-Hill Education.

Purpose of Chapter

The purpose of this chapter is to bring together in one place various issues surrounding the fixed-flexible exchange rate debate, and to survey some hybrid systems of fixed and flexible rates. The material builds upon points made in earlier chapters and prepares the students for the discussion of actual international monetary systems in the next chapter. IV.

Teaching Tips

A. The choice of an appropriate exchange rate regime is critical for many developing countries. Often faced with non-responsive economic systems and institutional rigidities, they experience domestic inflation problems that cannot be effectively overcome. In such an environment, tying the home currency to a major currency such as the dollar or euro or yen is very tempting. The case of Slovenia’s “Big Bang” approach to changing over to the euro is a good contemporary case to discuss with your students, and it gives them an appreciation of the impact of such an exchange rate decision. B. The “In the Real World” box on pages 725-26 deals with the influence of risk on trade volume. We have leaned toward the conclusion that exchange risk reduces trade to some extent. However, it is useful to emphasize that this is a controversial area and that there is no really clear answer – if you disagree with us, please do not hesitate to explain why to the students. C. Note the framework of the Hutchison and Walsh discussion on page 735’s “In the Real World” box. They are not concluding that there were fewer shocks in the flexible-rate period; rather, they are concluding that, for any given shock, Japan was more insulated in the flexiblerate period than in the fixed-rate period. D. The vicious circle hypothesis early in the chapter can easily be related to hyperinflation and PPP discussed in previous Chapters 20 and 22. E. Regarding the “In the Real World” box on page 745, note that Colombia stopped having a strict crawling peg in 1991. However, we still find the Colombian case interesting, and the general strategy has certain appeal for avoiding some of the disadvantages of both a freely flexible and a fixed exchange rate system.

We discuss the EMU in detail in the next chapter, but that material could easily be utilized here. G.

Answers to End-of-Chapter Questions and Problems

1. Other things equal, a country that is willing to pursue continually expansionary policy in order to keep unemployment low (moving beyond its natural level of output and employment) will experience greater inflation than a country more willing to “accept” more unemployment (e.g., be at the natural level of output or below it). The more inflationary country will lose international reserves to the less inflationary country. To avoid running out of reserves, the more inflationary country will eventually have to devalue its currency (or impose continuallyincreasing exchange controls). The less inflationary country may also decide to revalue its currency upward to avoid the inflationary stimulus provided by its buildup of reserves. 2. A case that flexible rates can reduce the flow of foreign direct investment (FDI) is built around the fact that, if prices do not move exchange rates in purchasing-power-parity fashion, the real value of the return flow of profits and dividends when converted into domestic currency is uncertain and investing abroad can therefore result in a loss. On the other hand, firms may invest in a foreign country rather than export to the country if exchange rate variations cause exporting to be uncertain and if the firm plans to reinvest profits in the foreign country. In addition, flexible rates may mean fewer home country restrictions on the outflow of investment for a country that would have a chronic BOP deficit under fixed rates, or fewer restrictions on inward foreign investment by a country worried about the inflationary impact of capital inflows. Hence, other things equal, FDI could be greater than under fixed rates. 3. Generally speaking, a country more susceptible to external rather than internal shocks would tend to prefer a flexible rate. External real shocks conceptually would have no impact on national income in the flexible-rate case but would be transmitted onto national income with a fixed rate. However, external monetary shocks will have an impact on income under either exchange rate system, and which system produces the greater income response is not certain. (It depends on the relative slopes of the BP and LM curves, and the direction of income response even differs between fixed and flexible rates if the BP curve is flatter than the LM curve). A country subject to internal monetary shocks would prefer fixed rates, since such shocks have a greater impact on national income under flexible rates. Internal real shocks have a greater impact on income under a flexible rate if the BP curve is steeper than the LM curve, and a smaller impact if the BP curve is flatter than the LM curve.

Chapter 28 - Fixed or Flexible Exchange Rates?

4. If you believe that markets maximize welfare, the conclusion in the quote follows if the exchange rate is a true scarcity price and reflects the true relative purchasing power of currencies. Then consumers and producers would indeed be able to direct their purchases and production according to true opportunity costs. (This assumes that market failure situations such as externalities and monopoly do not exist.) However, distortions in the exchange rate due to rumors and speculation can mean that the exchange rate doesn’t truly reflect opportunity costs and purchasing power, in which case maximum welfare is not assured. A fixed rate could conceptually be the true scarcity rate, but this seems highly unlikely to be the case over any time period other than the extremely short run. 5. Not necessarily. If underlying inflation rates and monetary conditions are compatible, for example, there may be little reason for speculators to expect prolonged currency movements in one direction, and any speculation may therefore be stabilizing. With stable monetary conditions, there will also be few abrupt changes in interest arbitrage capital flows. In addition, if real factors underlying the demand and supply of foreign exchange are stable, there may not be much movement in exchange rates because of shifts in the current account and direct investment flows. However, the above situations may be highly unlikely to be realized in practice, and unstable policies and conditions and autonomous real shocks can cause the exchange rate to change. 6. Risk can be detrimental to trade and international specialization if forward markets (and derivatives markets in general) are not well-developed; risk can also be detrimental to world welfare if direct investment flows are inhibited because of the risk. However, absorbing risk constitutes a very important feature in entrepreneurship, innovation, and a dynamic economy. If the degree of risk can be quantified and predicted, entrepreneurial activity in the pursuit of profit opportunities can proceed and can obviously enhance welfare. 7. A currency board has potential as a useful, practical arrangement for a country if that country has been facing severe inflationary problems due to rapid money creation by the central bank (on its own or in its passive financing of government budget deficits). The currency board arrangement can rein in such inflation because it forces the money supply to be firmly linked to the supply of foreign assets available to the country. However, the country must be committed to the idea of fiscal and monetary discipline and must be ready to make its internal economy’s behavior subject to the size and flow of external assets. It also must have the political will to stick with the currency board even when balance-of-payments deficits lead to contraction of the money supply and to possible deflation, recession, and unemployment. If political will and economic discipline are not present, the currency board arrangement in the country will likely be short-lived.

Chapter 28 - Fixed or Flexible Exchange Rates?

8. The world as a whole might be an optimum currency area if factors of production could move freely among all countries. Then any shifts in demand, for example, would produce supply responses as factors moved, and there would not necessarily be a problem of “pockets” of inflation in some countries and of unemployment in others. In addition, if national governments are maintained (rather than the formation of a world government), there would need to be similarity in policy goals across countries. The case for industrialized countries (ICs) being an optimum currency area could be defended by noting that a high degree of capital mobility exists among the ICs and that the ICs have relatively large trade among themselves (i.e., are relatively open) and have relatively little trade with developing countries (although such trade has been increasing in relative importance in recent years). However, there are clearly barriers to labor mobility, and policy targets are not identical. The case for integrating all developing countries into an optimum currency area is weak – they trade relatively little with each other, have considerably different inflation rates, and have only modest factor mobility among themselves. 9. This is obviously an opinion question, and the student’s answer may depend on whether he or she is a “glass half-full” or a “glass half-empty” person. The statement’s position could be defended, for example, by saying that the risks regarding trade and investment in a flexible rate system are still present to some extent with the hybrids, as are some of the resource misallocation effects with respect to fixing the exchange rate. On the other hand, international reserves may be less necessary in the hybrid systems than with a fixed rate, and some “discipline” is called for in a system such as the “wider bands.” Additional points pertaining to this question are given in the chapter. 10. Chile’s increased intervention in the foreign exchange market was designed to keep the Chilean peso from rising so much due to the foreign investment inflows. A more rapid rise in the peso would have caused a decline in exports, a rise in imports, and therefore a worsening of the current account and potential downward pressure on GDP. The reserve buildup and the foreign investment inflows are related because, with more fixity in the exchange rate, Chile’s international reserves had to rise because the incipient BOP surplus was not allowed to eliminate itself through an exchange rate change and hence became an actual BOP surplus. 11. A “true” (optimum) currency area preserves its fixed exchange rates by containing an effective BOP adjustment mechanism. Because of this effective mechanism, which can certainly be partly composed of coordinated macro policies, there is confidence in the fixed exchange rates and financial capital flows can play a stabilizing, non-speculative role in the economies. On the other hand, a “pseudo” currency area lacks an effective adjustment mechanism and can experience difficulties if business cycles are out-of-phase in the member countries and if macro policies do not concern themselves with preserving the fixed exchange rates. The lack of an effective adjustment mechanism can also trigger destabilizing capital flows. The distinction is useful because it focuses on the need for effective adjustment in order to attain a successful union, and it enables the analyst to make judgments about the likely success of any move toward monetary union by examining the structures and policy objectives of the proposed members.

What case could be made for a wider “band” of permitted exchange rate changes of the home currency against some foreign currencies (say 15 percent) than against some other foreign currencies (say 10 percent)? What case could be made against this difference in width of permitted variations? Explain. 5. Using the IS/LM/BP framework, explain how two of the following shocks impact on the domestic economy under flexible exchange rates and under fixed exchange rates. (a) an increase in the foreign rate of interest (b) a decrease in foreign income (c) a decrease in foreign prices 6. How could exchange rate protection of, for example, 10 percent, be duplicated in its effects across export and import-substitute industries by using tariffs and subsidies instead? Explain. Suppose that you are a firm in an import-substitute industry that is currently receiving less protection than most other import-substitute industries. Would you be in favor of scrapping the existing protection framework and adoption of exchange rate protection as an alternative policy? Explain. 7. Describe the features of a currency board arrangement. Then indicate general conditions under which the adoption of a currency board by a country would be desirable for the country. 8. If an important oil exporter such as Saudi Arabia were successful in raising the price of petroleum in the next few weeks, would a flexible exchange rate or a fixed exchange rate for the United States be better for mitigating the negative economic impact upon the United States? Why? B.

III.

Purpose of Chapter

The purpose of this chapter is to acquaint students with the desirable features of an effective international monetary system, to review the characteristics and problems of the Bretton Woods system, and to discuss contemporary international monetary arrangements and difficulties (including the Asian Crisis and the current global recession). Some suggested reforms of the current international monetary system are also considered, and brief consideration is also given to views held by developing countries regarding the international monetary system. IV.

Teaching Tips

A. Students often fail to appreciate the importance of a smoothly-functioning international monetary system. The devastating trade experience of the 1930s, when chaos reigned in international finance, serves as a reminder of this importance. You should stress to the students that the gains from trade discussed in the first part of the textbook are importantly dependent upon a stable monetary system such as is sought by the IMF, other institutions, and government leaders. B. In covering the IMF’s balance-of-payments loans, it would be useful to emphasize (as is also briefly mentioned in the chapter), that the IMF provides other types of loans than just these balance-of-payments loans. Additional lending has emerged, for example, for compensatory financing to alleviate the consequences of export instability and, importantly, for help for less developed countries (LDCs) with regard to their external debt problems (see Chapter 18). All of the IMF’s lending facilities are described in more detail in the early pages of the IMF’s monthly publication, International Financial Statistics. C. Some updating is periodically necessary with respect to Table 3 on exchange rate arrangements. These arrangements used to be indicated at the beginning of each month’s issue of International Financial Statistics but this is no longer the case. It is a little difficult to locate the information, and there is a time lag in the information, but we advise that you go to the IMF website (www.imf.org) and type “Exchange Rate Arrangements” or “De Facto Classification of Exchange Rate Regimes” into the Search box or locate the latest Annual Report of the Executive Board for the Financial Year. Another option is the IMF’s Annual Report on Exchange Arrangements and Exchange Restrictions. D. The Tobin proposal for a tax on short-term capital flows continues to be discussed in view of the huge volume of such flows (over $4 trillion of foreign exchange market transactions now occur in the world every business day). Hence, it is worthwhile to encourage discussion on the pros and cons of short-term capital controls. 29-2 © 2014 by McGraw-Hill Education.

Answers to End-of-Chapter Questions and Problems

1. An effective international monetary system needs to provide for relatively quick and smooth adjustment to imbalances in countries’ balance-of-payments positions. In addition, if exchange rates are not completely flexible, there must exist an adequate supply of internationally acceptable reserve assets so that effective intervention can be carried out without resort to trade and exchange controls. Because countries seem to differ in their internal macroeconomic target preferences, adjustment to and financing of imbalances should also be able to be undertaken without disruption of internal economic performance. Whether the current system meets these requirements is a matter of opinion. Some would say that the increasing exchange rate flexibility present in currencies provides for continuing adjustment without major interference in the attainment of domestic goals; others would say that domestic policy autonomy still needs to be sacrificed because of the need for coordination across countries, and that exchange rate changes are too slow in correcting current account imbalances. Also, many LDCs (who often have pegged rates) maintain extensive trade and exchange controls for balance-of-payments reasons, despite recent liberalization. 2. The problems with the Bretton Woods system are discussed in the chapter. The current system may provide greater adjustment of imbalances without undue interference with domestic performance, and the freedom of choice in exchange arrangements in the current system means that there is less danger of a “collapse” of the system as occurred with Bretton Woods. Further, the “confidence” problem seems to have been reduced. However, the increased international capital mobility since Bretton Woods has generated unstable exchange rates. Current account imbalances are also still prolonged, and the transmission of business cycles across countries is greater than was expected. Further, the level of international reserves may be inadequate in many LDCs. 3. An SDR is, like gold, an internationally acceptable reserve asset that is not simultaneously in use as a national currency. In addition, the growth rate of the asset can be kept relatively low, and the value of the asset is more stable than the value of any single (component) national currency. However, the SDR does not have a fixed official price (as gold did when it served as the principal reserve asset), and the SDR is not a physical asset with intrinsic value (it is only a bookkeeping entry at the IMF). SDRs can be used (within limits) in settlement of payments imbalances between countries and can provide international liquidity to SDR holders. Critical to the success of SDRs is that they have relative stability in value and, most importantly, that surplus countries are willing to accept SDRs in payment of imbalances. However, SDRs continue to be a very small fraction of international reserve assets held by central banks.

Chapter 29 - The International Monetary System: Past, Present, and Future

4. The growth of the world money supply is dependent on only one source in either system (the world gold supply in one system, decisions at the world central bank in the other). Both rely on basically fixed exchange rates, and both have a mechanism for adjustment to imbalances in countries’ BOP positions. Also, both systems tend to sacrifice national autonomy in the pursuit of domestic goals to the requirement of external balance. An important difference between the systems is that the supply of gold is basically independent of international monetary needs, whereas the world central bank can control the growth of reserve assets. There are also competing demands for gold from the private sector that could potentially cause instability for the gold standard, while potentially destabilizing private sector activities with respect to a world currency in the world central bank plan could presumably be offset (at least in theory) by actions of the bank. 5. The original central purposes of the IMF were to provide relative stability in exchange rates through a pegged-rate system, to combine BOP adjustment with national autonomy in domestic macroeconomic policies, to encourage freedom in trade and payments (although capital controls were permitted in some circumstances), and to provide short-term financing for countries with BOP difficulties. Since the Bretton Woods system collapsed, pegged rates are no longer required but disruptive exchange rate movements are to be avoided, and the IMF has often expressed its desire to have SDRs substitute for gold and dollars as the principal assets in the international monetary system. Surveillance is justified by the IMF to meet its goal of avoiding disruptive and destabilizing movements in exchange rates. 6. With respect to a flexible-rate system, the target zone proposal permits the exchange rate to perform its adjustment function to some extent, allows for some protection against the transmission of real shocks across countries, and prevents speculation from driving currencies to wide swings. It also allows fiscal policy to perform a role in meeting internal goals. However, the freedom of exchange rates to move beyond narrow limits could potentially lead to wasteful resource movements as rates changed. There could also be enhanced risks associated with trade and foreign investment as compared to a fixed-rate system, and internal shocks could also generate greater instability in national income than would be the case with a fixed-rate system. As with a fixed-rate system, the target zone system provides for some discipline and coordination in domestic macroeconomic policies, and, because exchange rates are limited in variability to some extent, trade and foreign investment may not be deterred because of exchange risk. However, countries may not be able to attain their preferred inflation/unemployment tradeoffs because of having to take corrective policy steps regarding the exchange rate as the ceiling and floor of the zones are reached (although the ceiling and floor may not be reached in the Krugman version). The intervention needed could transmit business cycles across countries. If the intervention were predicted to be unsuccessful, one-way bets for speculators could also exist. Hence, the avoidance of destabilizing speculation crucially depends on confidence in the monetary authorities to keep rates within the limits. 7. The logic of the statement is that coordinated policies would keep real exchange rates stable because countries will not be having incompatible inflationary stances, for example. (This assumes that the inflation differences are not entirely offset by relative purchasing-power-parity exchange rate movements, in which case no coordinated policies would be necessary.) However,

Chapter 29 - The International Monetary System: Past, Present, and Future

if the countries have compatible inflationary stances (or if relative PPP holds), there will be no need to specify ceilings and floors since the rates would not vary to any significant extent anyway: a fixed-rate system might as well be used. However, proponents of the target zones could say that the target zone system is superior to fixed rates because it provides more leeway in domestic policy, and they could also say that PPP tends to hold. 8. Advantages include the decreased exchange rate risk associated with foreign trade and investment, which would enhance specialization and the gains from trade and would allocate capital more effectively toward its most productive uses. In addition, if member countries are adhering to the convergence criteria, more stable growth and less disruption from exchange rate crises would occur. Further, of course, there are political and economic advantages to a country from being a member of a group that is a very important player in world political activity and in world markets. Potential disadvantages would be that each country is less insulated from real shocks in other EU countries, and that national monetary autonomy is basically lost. Also, a tight money policy in a dominant country such as Germany could leave a smaller country with more unemployment than it desired in accordance with its own unemployment/inflation tradeoff. This tension is also evident in recent years in smaller countries such as Greece and Portugal, which have been pressured to adopt austerity policies by the larger EMU countries and by the European Central Bank.

Essay Questions

1. Because different inflation/unemployment trade-offs can make it very difficult for a fixed-rate system to be maintained, how could the creators of the Bretton Woods system have thought that that system would provide for some autonomy in domestic macroeconomic policy? Explain. 2. SDRs were first introduced as a means of strengthening the Bretton Woods system. If the Bretton Woods system had not collapsed soon after the introduction of SDRs, how (if at all) could SDRs have potentially contributed to alleviating the liquidity problem? The confidence problem? The adjustment problem? Why do you suppose that, since their introduction, SDRs have remained such a small fraction of international reserves? Explain. 3. Why did the Bretton Woods system break down? Do you think that that breakdown and the subsequent adoption of much greater flexibility in the value of the dollar have been “good” from the standpoint of the United States? Why or why not? 4. Some economists doubt whether the Bretton Woods system could have survived the OPEC and primary product price “shocks” of the mid-1970s and the subsequent stagflation period. What reasons could be used to support this position? Would a gold standard have performed ‘better” or “worse” than the Bretton Woods system during this time? Explain.
