Yale Environment 360Off the Pedestal: Creating a New Vision of Economic Growthby James Gustave Speth
Is anything in America more faithfully followed than economic growth? Its movements are constantly watched, measured to the decimal place, deplored or praised, diagnosed as weak or judged healthy and vigorous.

The ecological economist Herman Daly has reminded us that if neo-classical economists were true to their trade, they would recognize that there are diminishing returns to growth. Most obviously, the value of income growth declines as one gets richer and richer. Similarly, growth at some point has increasing marginal costs. For example, workers have to put in too many hours, or the climate goes haywire. It follows that for the economy as a whole, we can reach a point where the extra costs of more growth exceed the extra benefits. One should stop growing at that point. Otherwise the country enters the realm of “uneconomic growth,” to use Daly’s delightful phrase, where the costs of growth exceed the benefits it produces.
