According to a 1989 analysis by
Milton Friedman and
Anna Schwartz, the recession of 1920–1921 was the result of an unnecessary contractionary monetary policy by the
Federal Reserve Bank.
Paul Krugman agrees that high interest rates due to the Fed's effort to fight inflation caused the problem. This did not cause a deficiency in aggregate demand but in aggregate supply. Once the Fed relaxed its monetary policy, the economy rapidly recovered. Additionally,
Allan H. Meltzer suggests that since the U.S. was on the
gold standard, the flight of gold from hyper-inflationary Europe to the U.S. raised the nominal stock of high-powered
base money. This ended the deflation and contributed to the economic recovery.
James Grant discusses in his 2014 book,
The Forgotten Depression, 1921, why the depression of 1920–1921 was relatively short compared to the 21st century's economic recession and the following economic downturn that started in 2007. "The essential point about the long ago downturn of 1920–1921 is that it was kind of the last demonstration of how a price mechanism works and the last governmentally unmediated business cycle downturn, meaning it was the last one that the government didn't attempt to treat with fiscal intervention with much lower interest rates. In fact, the FED, then still wet behind the ears as it only had been founded in 1914, actually raised rates in the face of a truly brutal deflation."
Thomas Woods, a proponent of the
Austrian School, argues that President Harding's
laissez-faire economic policies during the 1920–1921 recession, combined with a coordinated aggressive policy of rapid government downsizing, had a direct influence on the rapid and widespread private-sector recovery. Woods argued that, as there were massive distortions in private markets due to government economic influence related to demands of World War I, an equally massive correction to the distortions needed to occur as quickly as possible to realign investment and consumption with the new peacetime economic environment. In a 2011 article, Daniel Kuehn, a proponent of Keynesian economics, questions many of the assertions Woods makes about the 1920–1921 recession. Kuehn notes the following: • the most substantial downsizing of government was attributable to the Wilson administration, and occurred well before the onset of the 1920–1921 recession. • the Harding administration raised revenues in 1921 by expanding the tax base considerably at the same time that it lowered rates. • Woods underemphasizes the role the monetary stimulus played in reviving the depressed economy and that, since the 1920–1921 recession was not characterized by a deficiency in aggregate demand, fiscal stimulus was unwarranted. ==United Kingdom==
