An interesting recent
piece by Justin Fox at the Harvard Business Review discusses why more and more the leading intellectuals of our day are economists instead of historians. Fox's initial conjecture was that economists tend to be much better at keeping our professional work incomprehensively impressive while their popular work is very approachable. Historians, he contends, don't separate these two functions as well.
Fox cites an unnamed economist as suggesting that people are drawn to economists because most of their work, unlike historians, revolves around predicting the future (unsuccessfully, but still). I'm always amazed to see this description of economics brought up so frequently by economists, especially since it is in all cases followed immediately by "Of course,
I don't work on forecasting, but..." I'm not sure what economics they're reading, but most of the work I see involves trying to explain the recent past, not make influential predictions of the future. And I'm one of these darned Macroeconomists the other guys are always complaining about. For people who are actively trying to divine the future, I'd check out folks in finance and investing.
Historians tend to see the shift in a different light:
It's that, especially in the U.S., only the tiniest minority of academic historians concern themselves anymore with matters of economic policy (or diplomacy, or war, or politics in the big-picture sense). The discipline has moved mostly to the study of identity (gender, race, etc.) and culture, ceding territory to the economists and political scientists.
This is essentially the argument Ezra Klein aligns with (although he still likes that inexplicable divination argument) in
his comment on the piece:
But I also think that the answer is partly that the public debate is substantially about what's happening with the economy. That's true when you're talking about the economy, but it's also true when you're talking about something like health care, where the majority of the discussion focused on the bill's impact on deficits and premiums and paychecks. And it'll be true when talking about financial regulation (will it reduce the availability of credit?) and mostly true when talking about cap-and-trade (will it hurt growth or my bank account?).
I think there's a fair amount of traction to this argument, but it doesn't really explain why the historians decided to "cede territory" to the economists in the first place.
Now, I hesitate to offer this explanation for fear of embracing hubris, but maybe historians have let economists deal with economic matters because
economists are better at it. I would never claim that the answers we offer are flawless, but when it comes to identifying the most important influences on the important decisions people make (most of which are even explicitly about market exchange), economics seems to have at least as much to offer as any other discipline, and in many cases more. I tend to think people listen to economists on these matters because what economists have to say has proven more beneficial than the competition. And competition, as Fox notes, is a good thing:
Over the past half century, economists have come to utterly dominate thinking about economic matters, and begun to insinuate themselves into lots of other fields too. Business education, and business advice, has certainly become much more economics-oriented. Which isn't all bad. But even an economist would agree that we could use more competition in the marketplace of ideas. Right?
Fox sees economics dominating the ideas market as something that will result in less competition. I think it is at least as likely that economics dominates as a result of increased competition.
One more bit of evidence? Consider one area in which economics is really bad at offering useful ideas: the study of identity, where the clear winner is historians and the other humanities.
