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:
Perspectives on capitalism by school of thought
The Chicago School of economics is best known for its free market advocacy and monetarist ideas. According to Friedman and other monetarists, market economies are inherently stable if left to themselves and depressions result only from government intervention.
Friedman argued that the Great Depression was result of a contraction of the money supply controlled by the Federal Reserve and not by the lack of investment as John Maynard Keynes: "There is likely to be a lag between the need for action and government recognition of the need; a further lag between recognition of the need for action and the taking of action; and a still further lag between the action and its effects". Ben Bernanke, former Chairman of the Federal Reserve, is among the economists today generally accepting Friedman's analysis of the causes of the Great Depression.
