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.
Charles P. Kindleberger
His 1973 and 1986 book "The World in Depression 1929–1939" (University of California Press, 1986 [Revised and Enlarged Edition]) advances an idiosyncratic, internationalist view of the causes and nature of the Great Depression. Blaming the peculiar length and depth of the Depression on the hesitancy of the US in taking over leadership of the world economy when Britain was no longer up to the role after World War I, he concludes that "for the world economy to be stabilized, there has to be a stabilizer—one stabilizer", by which, in the context of the interwar years at least, he means the United States. In the last chapter "An Explanation of the 1929 Depression", Kindleberger lists the five responsibilities the US would have had to assume in order to stabilize the world economy:Kindleberger was highly skeptical of Milton Friedman and Anna Schwartz's monetarist view of the causes of the Depression, seeing it as too narrow and perhaps dogmatic, and dismisses out of hand what he characterized as Paul Samuelson's "accidental" or "fortuitous" interpretation. "The World in Depression" was praised by John Kenneth Galbraith as 'the best book on the subject'.
