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:
Great Depression in the United States
The Wall Street Crash of 1929 is often cited as the beginning of the Great Depression. It began on October 24, 1929, and was the most devastating stock market crash in the history of the United States. Much of the stock market crash can be attributed to exuberance and false expectations. In the years leading up to 1929, the rising stock market prices had created vast sums of wealth for those invested, in turn encouraging borrowing to further buy more stock. However, on October 24 (Black Thursday), share prices began to fall and panic selling caused prices to fall sharply. On October 29 (Black Tuesday), share prices fell by $14 billion in a single day, more than $30 billion in the week. The value that evaporated that week was 10x more than the entire federal budget and more than all of what the U.S. spent on World War I. By 1930 the value of shares had fallen by 90%.
