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:
Economic history of the United States
Following the stock market crash, the worldwide economy plunged into the Great Depression. The U.S. money supply began to contract by one-third. The protectionist Smoot–Hawley Tariff Act incited retaliation by Canada, Britain, Germany and other trading partners. Congress, in 1932, worried about the rapidly growing deficit and national debt, and raised income tax rates. Economists generally agree that these measures deepened an already serious crisis. By 1932, the unemployment rate was 25%. Conditions were worse in heavy industry, lumbering, export agriculture (cotton, wheat, tobacco), and mining. Conditions were not quite as bad in white collar sectors and in light manufacturing.
