It is possible to see Keynesian and Schumpeterian ideas as complementary. Keynes is about short-run economic fluctuations brought about by erratic variations in the willingness of investors and governments to spend; Schumpeter is about the long-run trajectory driven by the erratic march of technological progress. This complementarity only became clear later, after both men had died, when economic growth became an explicit objective of public policy and topic of systematic analysis. Schumpeter was left frustrated by the younger generation’s affinity for his rival. In any case, the “preliminary volume” never materialized.
The world turns. Today, some sixty years after their deaths, Schumpeter’s star probably outshines Keynes’s. The business cycle has receded in importance, partly because the large industrial economies have sprouted a more stable structure, and partly because the lessons that Keynes taught have been learned by central banks and finance ministries. Instead, long-term economic growth has moved to the top of the political and intellectual agenda, and that was Schumpeter’s topic. As Robert Lucas memorably put it, once you have begun to think about economic growth, it is hard to think about anything else. It is a pity that troubled old Schumpeter did not live to see the triumph of his obsession. (en) |
