So it was in San Diego in early January at the annual meetings among the gathered economists, dismal professionals to a man and (occasional) woman. The New York Times on January 8 aptly summarized the concerns: high deficits and public debt, low interest rates, trade wars, and slow productivity growth. According to the Times, these warnings were echoed by economists from the World Bank, the Federal Reserve, from Washington think tanks and, of course, from Harvard.
Beneath the ominous prognoses lie two impulses. One is the natural human desire not to be embarrassed—yet again—by failing to have warned that things may go bad. The academics quoted in the Times were in several cases architects of past disasters, or at best blind and mute as disasters approached. It would not do to have the same said again, and if a disaster does not occur, few will remember the warnings. The other impulse is intellectual inertia: The economists, like France’s Bourbons, learn nothing and forget nothing; they cast their omens in terms of parables read in textbooks many decades back. To change ideas now would call into question the very foundation of their careers.
