Grown-Up Economics Beth Stratford It is hard to find an elected leader anywhere in the capitalist world not utterly preoccupied with maximizing growth. Relentless increases in production and consumption year after year: this is the holy grail, even if it means encouraging people to buy things they don’t need with money they don’t have. Even if it means pushing us all closer to ecological disaster. The widespread conflation of economic growth with social progress is frustrating for anyone familiar with the research on wellbeing. Yes, booms and busts affect happiness in the short term, but in the long run, there is no evidence that economic growth at a national level delivers greater happiness. This shouldn’t be such a puzzle. After all, wellbeing is underpinned by a range of conditions: economic security is one – hence the drop in life satisfaction during the uncertainty of economic crisis – but we also need social cohesion and solidarity, a sense of agency, mental and physical health, time for family and friends, access to nature, a benign climate and so on. Paradoxically, many of these conditions of wellbeing are threatened by the blinkered pursuit of economic growth. The global economy is currently growing at 3% per year. If that trend continues, within 25 years the global economy will have doubled in size. Before the end of the century global production and consumption will have increased ten-fold. If economic growth continues to go hand in hand with growth in the volume of natural resources that we convert into finished products and wastes, this won’t be a pretty future. Clearly, a parasite that doubles its use of resources every quarter century is going to eventually kill its host. Some believe that breakthroughs in efficiency can solve this predicament. The trouble is that efficiency savings which reduce the need for energy and material inputs tend to lead to lower prices and therefore stimulate even more consumption. This is a pattern observed for the last 300 years, nicknamed the ‘rebound effect’ or the ‘Jevons Paradox’ after the English economist William Stanley Jevons who observed in 1865, in relation to coal, ‘it is wholly a confusion of ideas to suppose that the economic use of fuel is equivalent to a diminished consumption. The very opposite is the truth’. 34 ❙
