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.
New Deal
Lowell E. Gallaway and Richard K. Vedder argue on the basis of Austrian School of economics theories that the Great Depression was caused by wages being too high which they say had caused a loss of depositor confidence which caused the bank runs. They further conclude that the "Great Depression was very significantly prolonged in both its duration and its magnitude by the impact of New Deal programs". They suggest that without Social Security, work relief, unemployment insurance, mandatory minimum wages and without special government-granted privileges for labor unions, business would have hired more workers and the unemployment rate during the New Deal years would have been 6.7% instead of 17.2%. Amity Shlaes wrote that "from 1929 to 1940, from Hoover to Roosevelt, government intervention helped to make the Depression Great". Shlaes said that the NRA was misguided because it used price setting to fix monetary problems. According to Shlaes, Roosevelt's experimentation frightened business into inaction and prevented recovery. Eric Rauchway showed that Shlaes tried to diminish the economic growth by referring to the unrepresentative Dow Jones Industrial Average. He continued that usually a historian or economist would have referred to the gross domestic product, which according to the Historical Statistics of the United States grew impressively by 9% annually during Roosevelt's first term and by 11% annually after the short recession of 1937–1938.
