The United States economy completed its recovery from the Great Depres
sion in 1942, restoring full-employment output in that year after 12 y
ears of below-full-employment performance. Fiscal policies were not th
e most important factor in the 1933 through 1940 phase of the recovery
, but they became the most important factor after 1940, when the recov
ery was less than half-complete. World War II fiscal policies were, th
en, instrumental in the overall restoration of full-employment perform
ance.
