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:
Causes of the Great Depression
In a 1995 survey of American economic historians, two-thirds agreed that the Smoot-Hawley tariff act at least worsened the Great Depression. However, many economists believe that the Smoot-Hawley tariff act was not a major contributor to the great depression. Economist Paul Krugman holds that, "Where protectionism really mattered was in preventing a recovery in trade when production recovered". He cites a report by Barry Eichengreen and Douglas Irwin: Figure 1 in that report shows trade and production dropping together from 1929 to 1932, but production increasing faster than trade from 1932 to 1937. The authors argue that adherence to the gold standard forced many countries to resort to tariffs, when instead they should have devalued their currencies. Peter Temin argues that contrary the popular argument, the contractionary effect of the tariff was small. He notes that exports were 7 percent of GNP in 1929, they fell by 1.5 percent of 1929 GNP in the next two years and the fall was offset by the increase in domestic demand from tariff.
