Economics has problems. Because of Samuelson, it got a half-century case of physics envy. Then people read Schumpeter and McCloskey, and realized economics can’t predict a whit. Economics became useful (ex post) stories, a bit like archaeology or geology.
Then came The End of History (1989) and The Great Recession (2008), and weirdos still talk of evolving economics, but into what they can’t explain. Like Marx redux, they blame ‘capitalism’ or neoliberals, though they can’t go whole hog back to old-style apparatchik economics. Some think that the missing link is a co-equal infant science called psychology.
What to do? At one point, one way out was to study ‘institutions.’ But this seemed like hard work — too much scholarly pain for little gain. But gains there were if you read Coase or Ostrom, or (if you want Keynes to shudder) Hayek.
Perhaps that’s just the way it is. Economists are more like chickens with no heads but imaginarily pecking away at crumbs of intellectual progress. Some toil away at saving the world from falling over a cliff, much like Salinger’s Catcher in the Rye. That’s at least humanitarian if mostly unheralded.
Keynes did say that economists should be more like dentists. Dentists are good guys who help people prevent cavities and enable them to smile. The economist can then go home after a day’s work knowing the economy will still do its wayward thing but not die.
