Paul Krugman: The Urge to Purge

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?
