Paul Krugman: The Urge to Purge

We need to purge rotten economic policy out of our economic system:

The Urge to Purge, by Paul Krugman, Commentary, NY Times: When the Great Depression struck, many influential people argued that the government shouldn’t even try to limit the damage. According to Herbert Hoover, Andrew Mellon, his Treasury secretary, urged him to “Liquidate labor, liquidate stocks, liquidate the farmers. ... It will purge the rottenness out of the system.” Don’t try to hasten recovery, warned the famous economist Joseph Schumpeter, because “artificial stimulus leaves part of the work of depressions undone.”

Like many economists, I used to quote these past luminaries with a certain smugness. After all, modern macroeconomics had shown how wrong they were, and we wouldn’t repeat the mistakes of the 1930s, would we?

How naïve we were. It turns out that the urge to purge — the urge to see depression as a necessary and somehow even desirable punishment for past sins, while inveighing against any attempt to mitigate suffering — is as strong as ever. Indeed, Mellonism is everywhere these days. Turn on CNBC or read an op-ed page, and the odds are that you ... encounter an alleged expert ranting about the evils of budget deficits and money creation, and denouncing Keynesian economics as the root of all evil.

Now, the fact is that these ranters have been wrong about everything, at every stage of the crisis, while the Keynesians have been mostly right. ... But the Mellonites just keep coming. The latest example is David Stockman...

So what should we be doing? ... To deal with the crisis..., we need monetary and fiscal stimulus, to induce those who aren’t too deeply indebted to spend more while the debtors are cutting back.

But that prescription is, of course, anathema to Mellonites, who wrongly see it as more of the same policies that got us into this trap. And that, in turn, tells you why liquidationism is such a destructive doctrine: by turning our problems into a morality play of sin and retribution, it helps condemn us to a deeper and longer slump.

The bad news is that sin sells. Although the Mellonites have, as I said, been wrong about everything, the notion of macroeconomics as morality play has a visceral appeal that’s hard to fight. Disguise it with a bit of political cross-dressing, and even liberals can fall for it.

But they shouldn’t. Mellon was dead wrong in the 1930s, and his avatars are dead wrong today. Unemployment, not excessive money printing, is what ails us now — and policy should be doing more, not less.
