Economic Recovery: Lessons from the Post-World War II Period by Cecil Bohanon, for Mercatus He is a professor of economics at Ball State University. Excerpts:
"The standard thinking of the day was that the United
States would sink into a deep depression at the war’s end. Paul
Samuelson, a future Nobel Prize winner, wrote in 1943 that upon
cessation of hostilities and demobilization “some ten million men will
be thrown on the labor market.”[3] He warned that unless wartime
controls were extended there would be “the greatest period of
unemployment and industrial dislocation which any economy has ever
faced.”[4] Another future Nobel laureate, Gunnar Myrdal, predicted that
postwar economic turmoil would be so severe that it would generate an
“epidemic of violence.”[5]
This, of course, reflects a
world view that sees aggregate demand as the prime driver of the
economy. If government stops employing soldiers and armament factory
workers, for example, their incomes evaporate and spending will decline.
This will further depress consumption spending and private investment
spending, sending the economy into a downward spiral of epic
proportions. But nothing of the sort actually happened after World War
II.
In 1944, government spending at all levels
accounted for 55 percent of gross domestic product (GDP). By 1947,
government spending had dropped 75 percent in real terms, or from 55
percent of GDP to just over 16 percent of GDP.[6] Over roughly the same
period, federal tax revenues fell by only around 11 percent.[7] Yet this
“destimulation” did not result in a collapse of consumption spending or
private investment. Real consumption rose by 22 percent between 1944
and 1947, and spending on durable goods more than doubled in real terms.
Gross private investment rose by 223 percent in real terms, with a
whopping six-fold real increase in residential- housing expenditures.[8]
The
private economy boomed as the government sector stopped buying
munitions and hiring soldiers. Factories that had once made bombs now
made toasters, and toaster sales were rising. On paper, measured GDP did
drop after the war: It was 13 percent lower in 1947 than in 1944. But
this was a GDP accounting quirk, not an indication of a stalled private
economy or of economic hardship. A prewar appliance factory converted to
munitions production, when sold to the government for $10 million in
1944, added $10 million to measured GDP. The same factory converted back
to civilian production might make a million toasters in 1947 that sold
for $8 million—adding only $8 million to GDP. Americans surely saw the
necessity for making bombs in 1944, but just as surely are better off
when those resources are used to make toasters. More to the point,
growth in private spending continued unabated despite a bean-counting
decline in GDP."
"between 1944 and 1947 private spending grew rapidly as
public spending cratered. There was a massive, swift, and beneficial
switch from a wartime economy to peacetime prosperity; resources flowed
quickly and efficiently from public uses to private ones.
Just
as important, the double-digit unemployment rates that had bedeviled
the prewar economy did not return. Between mid-1945 and mid-1947, over
20 million people were released from the armed forces and related
employment, but nonmilitary-related civilian employment rose by 16
million. This was described by President Truman as the “swiftest and
most gigantic change-over that any nation has made from war to
peace.”[9] The unemployment rate rose from 1.9 percent to just 3.9
percent. As economist Robert Higgs points out, “It was no miracle to
herd 12 million men into the armed forces and attract millions of men
and women to work in munitions plants during the war. The real miracle
was to reallocate a third of the total labor force to serving private
consumers and investors in just two years.”[10]"
"Although the GI Bill surely had a positive effect in the 1950s on the
educational level of U.S. workers, the bill played a very minor role in
keeping the immediate postwar unemployment rate low. At its height, in
the fall of 1946, the bill only took about 8 percent of former GIs to
college campuses and out of the workforce."
"In the years under discussion, however, no new government program was
facilitating this transition; indeed, it was the end of government
direction of the economy that facilitated the postwar boom in private
employment."
"When the war ended, however, the command economy was dismantled. By the
end of 1946, direct government allocation of resources—by edict, price
controls, and rationing schemes—was essentially eliminated.[15] Tax
rates were cut as well, although they remained high by contemporary
standards. By any measure, the economy became less subject to government
direction. Despite the pessimism of professional economists, resources
that previously would have been directed to the production of war goods
quickly found their way to other uses. The business community did not
share the economists’ despair. A poll of business executives in 1944 and
1945 revealed that only 8.5 percent of them thought the prospects for
their company had worsened in the postwar period. A contemporary
chronicler noted that in 1945-1946 businesses “had a large and growing
volume of unfilled orders for peacetime products.”[16] In fact, the
elimination of wartime economic controls coincided with one of the
largest periods of economic growth in U.S. history."
