Paul Krugman: Who Wants a Depression?

One unhappy lesson we’ve learned in recent years is that economics is a far more political subject than we liked to imagine. Well, duh, you may say. But, before the financial crisis, many economists — even, to some extent, yours truly — believed that there was a fairly broad professional consensus on some important issues.

This was especially true of monetary policy. It’s not that many years since the administration of George W. Bush declared that one lesson from the 2001 recession and the recovery that followed was that “aggressive monetary policy can make a recession shorter and milder.” Surely, then, we’d have a bipartisan consensus in favor of even more aggressive monetary policy to fight the far worse slump of 2007 to 2009. Right?
