The conventional wisdom holds that in the absence of government countercyclical policy, whether fiscal or monetary (or both), we cannot expect economic recovery — at least, not without an intolerably long delay. Yet the very opposite policies were followed during the depression of 1920–1921, and recovery was in fact not long in coming.

The economic situation in 1920 was grim. By that year unemployment had jumped from 4 percent to nearly 12 percent, and GNP declined 17 percent. No wonder, then, that Secretary of Commerce Herbert Hoover — falsely characterized as a supporter of laissez-faire economics — urged President Harding to consider an array of interventions to turn the economy around. Hoover was ignored.

Instead of "fiscal stimulus," Harding cut the government's budget nearly in half between 1920 and 1922. The rest of Harding's approach was equally laissez-faire. Tax rates were slashed for all income groups. The national debt was reduced by one-third.

The Federal Reserve's activity, moreover, was hardly noticeable. As one economic historian puts it, "Despite the severity of the contraction, the Fed did not move to use its powers to turn the money supply around and fight the contraction."[2] By the late summer of 1921, signs of recovery were already visible. The following year, unemployment was back down to 6.7 percent and it was only 2.4 percent by 1923.
