FDR's policies prolonged Depression

UCLA Newsroom: FDR's policies prolonged Depression by 7 years, UCLA economists calculate:

After scrutinizing Roosevelt's record for four years, Harold L. Cole and Lee E. Ohanian conclude in a new study that New Deal policies signed into law 71 years ago thwarted economic recovery for seven long years.

"This is exciting and valuable research," said Robert E. Lucas Jr., the 1995 Nobel Laureate in economics, and the John Dewey Distinguished Service Professor of Economics at the University of Chicago. "The prevention and cure of depressions is a central mission of macroeconomics, and if we can't understand what happened in the 1930s, how can we be sure it won't happen again?"
