Long Depression
In the United States, the Long Depression began with the Panic of 1873. The National Bureau of Economic Research dates the contraction following the panic as lasting from October 1873 to March 1879. At 65 months, it is the longest-lasting contraction identified by the NBER, eclipsing the Great Depression's 43 months of contraction. Figures from Milton Friedman and Anna Schwartz show net national product increased 3 percent per year from 1869 to 1879 and real national product grew at 6.8 percent per year during that time frame. However, since between 1869 and 1879 the population of the United States increased by over 17.5 percent, per capita NNP growth was lower. Following the end of the episode in 1879, the U.S. economy would remain unstable, experiencing recessions for 114 of the 253 months until January 1901.
Great Depression in the United States
The New Deal was, and still is, sharply debated. The business community, with considerable support from such conservative Democrats as Al Smith, launched a crusade against the New Deal, warning that a dangerous man had seized control of the economy and threatened America's conservative traditions. Scholars remain divided as well. When asked whether "as a whole, government policies of the New Deal served to lengthen and deepen the Great Depression," 74% of American university professors specializing in economic history disagreed, 21% agreed with provisos, and 6% fully agreed. Among respondents who taught or studied economic theory, 51% disagreed, 22% agreed with provisos, and 22% fully agreed.
