Causes of the Great Depression
Second, there are the monetarists, who believe that the Great Depression started as an ordinary recession, but that significant policy mistakes by monetary authorities (especially the Federal Reserve) caused a shrinking of the money supply which greatly exacerbated the economic situation, causing a recession to descend into the Great Depression. Related to this explanation are those who point to debt deflation causing those who borrow to owe ever more in real terms.
Causes of the Great Depression
According to Peter Temin, Barry Wigmore, Gauti B. Eggertsson and Christina Romer the biggest primary impact of the New Deal on the economy and the key to recovery and to end the Great Depression was brought about by a successful management of public expectations. Before the first New Deal measures people expected a contractionary economic situation (recession, deflation) to persist. Roosevelt's fiscal and monetary policy regime change helped to make his policy objectives credible. Expectations changed towards an expansionary development (economic growth, inflation). The expectation of higher future income and higher future inflation stimulated demand and investments. The analysis suggests that the elimination of the policy dogmas of the gold standard, balanced budget and small government led to a large shift in expectation that accounts for about 70–80 percent of the recovery of output and prices from 1933 to 1937. If the regime change would not have happened and the Hoover policy would have continued, the economy would have continued its free fall in 1933, and output would have been 30 percent lower in 1937 than in 1933.
