Long Depression
Nobel laureate economist Milton Friedman, author of "A Monetary History of the United States", on the other hand, blamed this prolonged economic crisis on the imposition of a new gold standard, part of which he referred to by its traditional name, The Crime of 1873. This forced shift into a currency whose supply was limited by nature, unable to expand with demand, caused a series of economic and monetary contractions that plagued the entire period of the Long Depression. Murray Rothbard, in his book "History of Money and Banking of the United States", argues that the long depression was only a misunderstood recession since real wages and production were actually increasing throughout the period. Like Friedman, he attributes falling prices to the resumption of a deflationary gold standard in the U.S. after the Civil War.
Herbert Hoover
Hoover pursued many policies in an attempt to pull the country out of depression, while attempting to restrain the federal government from becoming directly involved in commercial affairs. In the days following Black Tuesday, Hoover gathered business and labor leaders, asking them to avoid wage cuts and work stoppages while the country faced what he believed would be a short recession similar to the Depression of 1920–21. Some economists, such as Lee Ohanian, point to the resulting wage rigidity as a key cause of the severity of the Great Depression.
