Important claims and supporting citations
According to economic historian Alexander Field, U.S. total factor productivity growth rates were higher during the Great Depression years (1929–1941) than during the postwar Golden Age (1948–1973).
During the later stages of postwar economic convergence, total factor productivity growth slowed by 3 percentage points in Germany and 2 percentage points in Japan while remaining stable in other countries.
Economic research indicates that increases in human capital did not contribute significantly to Germany and Japan's postwar productivity catch-up relative to the United States.
Japanese production in 1945 fell to 10 percent of prewar levels, but economic recovery and rehabilitation were essentially complete by 1954.
The 1953 London Debt Agreement reduced West Germany's external debt from DM 29.7 billion to DM 14.5 billion, capped debt service at 3% of export earnings, and lowered its debt ratio to approximately 10% of GDP.
While the United States had historically been a net importer of consumer goods, it recorded a net export surplus of $1 billion in that category in 1947.
German manufacturing total factor productivity was approximately half of the US level in 1950, while Japanese manufacturing TFP was one-third of the US level in 1955.
US non-manufacturing labor productivity growth declined from 2.95% (1948–1972) to 1.29% (1972–1996), during which time manufacturing's share of the US economy contracted from ~30% to 10%.
