When Krugman Was Good

Relatively speaking, of course. It’s easy to forget that Paul Krugman was once a sensible thinker, at least in some areas. From a lengthy New Yorker profile:
Krugman’s tribe was academic economists, and insofar as he paid any attention to people outside that tribe, his enemy was stupid pseudo-economists who didn’t understand what they were talking about but who, with attention-grabbing titles and simplistic ideas, persuaded lots of powerful people to listen to them. He called these types “policy entrepreneurs”—a term that, by differentiating them from the academic economists he respected, was meant to be horribly biting. He was driven mad by Lester Thurow and Robert Reich in particular, both of whom had written books touting a theory that he believed to be nonsense: that America was competing in a global marketplace with other countries in much the same way that corporations competed with one another. In fact, Krugman argued, in a series of contemptuous articles in Foreign Affairs and elsewhere, countries were not at all like corporations. While another country’s success might injure our pride, it would not likely injure our wallets. Quite the opposite: it would be more likely to provide us with a bigger market for our products and send our consumers cheaper, better-made goods to buy. A trade surplus might be a sign of weakness, a trade deficit a sign of strength. And, anyway, a nation’s standard of living was determined almost entirely by its productivity—trade was just not that important.
Eventually, of course, Krugman became the very thing he despised. As Steve Landsburg famously put it, “Krugman leaves me wide-eyed with wonder at how much economics he has to forget to write those columns.”
