IF asked to identify the intellectual founder of their discipline, most economists today would probably cite Adam Smith. But that will change. Economists’ forecasts generally aren’t worth much, but I’ll offer one that even my youngest colleagues won’t survive to refute: If we posed the same question 100 years from now, most economists would instead cite Charles Darwin.

Darwin, renowned for the theory of evolution, was a naturalist, not an economist, and his view of the competitive struggle was different from Smith’s in subtle but profound ways. Growing evidence suggests that Darwin’s view tracks economic reality much more closely.

Smith is celebrated for his “invisible hand” theory, which holds that when greedy people trade for their own advantage in unfettered private markets, they will often be led, as if by an invisible hand, to produce the greatest good for all. The invisible hand remains a powerful narrative, but after the recent economic wreckage, skepticism about it has grown. My prediction is that it will eventually be supplanted by a version of Darwin’s more general narrative  one that grants the invisible hand its due, but also strips it of the sweeping powers that many now ascribe to it.

Smith’s basic idea was that business owners seeking to lure customers away from rivals have powerful incentives to introduce improved product designs and cost-saving innovations. These moves bolster innovators’ profits in the short term. But rivals respond by adopting the same innovations, and the resulting competition gradually drives down prices and profits. In the end, Smith argued, consumers reap all the gains.
