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:
Clarence Barber
Effects of the Great Depression in his youth motivated Barber to study economics . In 1978, Barber wrote ""On the Causes of the Great Depression"" where he made a link between demographics and economics. He cited how demand for housing in the U.S. began to drop beginning in 1926. Early in 1929, demand for housing dropped precipitously. The stock market crash in October of that same year was preceded by a decline in demand, Barber argues, that began with a lower formation of households concomitant with lower rates of marriage. After World War I, a birth dearth had resulted; a dearth that demographers have shown did not end until World War II ended. (see Causes of the Great Depression)
The death of young men as soldiers in World War I, coupled with the Flu Pandemic of 1918 wrought their eventual harm to the economy as a whole. The increase in secularization during the 'Roaring Twenties', as automobiles became widespread, and availability of electricity and electrical appliances and such, may have had its effect too. Barber showed in ""On Causes..."" that lower demand for mortgages and other loans preceded by some years a shortage of loan availability as the Great Depression deepened towards 1933.
