How Realistic is The Assumption of Profit Maximization?

HOW REALISTIC IS THE ASSUMPTION OF PROFIT MAXIMIZATION? The assumption of profit maximization has come under repeated criticism. Many economists have argued that this behavioral assertion is too simplistic to describe the complex nature and managerial thought processes of the modern large corporation. Two distinguishing characteristics of the modern corporation weaken the neoclassical assumption of profit maximization. To begin with, the modern large corporation is generally not owner operated. Responsibility for the day-to-day operations of the firm is delegated to managers who serve as agents for shareholders. One alternative to neoclassical theory based on the assumption of profit maximization is transaction cost theory, which asserts that the goal of the firm is to minimize the sum of external and internal transaction costs subject to a given level of output, which is a first-order condition for profit maximization.5 According to Ronald Coase (1937), who is regarded as the founder of the transaction cost theory, firms exist because they are excellent resource allocators. Thus, consumers satisfy their demand for goods and services more efficiently by ceding production to firms, rather than producing everything for their own use. Still another theory of firm behavior, which is attributed to Herbert Simon (1959), asserts that corporate executives exhibit satisficing behavior. According to this theory, managers will attempt to maximize some objective, such as executive salaries and perquisites, subject to some minimally acceptable requirement by shareholders, such as an “adequate” rate of return on investment or a minimum rate of return on sales, profit, market share, asset growth, and so on. The assumption of satisficing behavior is predicated on the belief that it is not possible for management to know with certainty when profits are maximized because of the complexity and uncertainties associated with running a large corporation. There are also noneconomic organizational objectives, such as good citizenship, product quality, and employee goodwill. The closely related theory of manager-utility maximization was put forth by Oliver Williamson (1964). Williamson argued that managers seek to maximize their own utility, which is a function of salaries, perquisites, stock options, and so on. It has been argued, however, that managers who place their own self-interests before the interests of shareholders by failing to exploit profit opportunities may quickly find themselves looking for work. This will come about either because shareholders will rid themselves of 5
Transactions costs refer to costs not directly associated with the actual transaction that enable the transaction to take place. The costs associated with acquiring information about a good or service (e.g., price, availability, durability, servicing, safety) are transaction costs. Other examples of transaction costs include the cost of negotiating, preparing, executing, and enforcing a contract.
