Causes of the Great Depression
In their 1963 book "A Monetary History of the United States, 1867–1960", Milton Friedman and Anna Schwartz laid out their case for a different explanation of the Great Depression. Essentially, the Great Depression, in their view, was caused by the fall of the money supply. Friedman and Schwartz write: "From the cyclical peak in August 1929 to a cyclical trough in March 1933, the stock of money fell by over a third." The result was what Friedman and Schwartz called "The Great Contraction" — a period of falling income, prices, and employment caused by the choking effects of a restricted money supply. Friedman and Schwartz argue that people wanted to hold more money than the Federal Reserve was supplying. As a result, people hoarded money by consuming less. This caused a contraction in employment and production since prices were not flexible enough to immediately fall. The Fed's failure was in not realizing what was happening and not taking corrective action. In a speech honoring Friedman and Schwartz, Ben Bernanke stated:
Comparisons between the Great Recession and the Great Depression
Nobel Prize–winning economist Paul Krugman predicted a series of depressions in his "The Return of Depression Economics" (1999), based on "failures on the demand side of the economy." On January 5, 2009, he wrote that "preventing depressions isn't that easy after all" and that "the economy is still in free fall." In March 2009, Krugman explained that a major difference in this situation is that the causes of this financial crisis were from the shadow banking system. "The crisis hasn't involved problems with deregulated institutions that took new risks... Instead, it involved risks taken by institutions that were never regulated in the first place."
