How much did falling military procurement drive manufacturing decline and inequality?
Core argument: The authors estimate the 1950s–1990s decline in U.S. military procurement spending explains roughly 18–30% of the decline in manufacturing and just under 10% of the rise in top-ten inequality.
We have shown that in the decades immediately following World War II, the Cold War was a major factor sustaining tight labor markets. On the labor demand side, military procurement increased demand for manufacturing workers and put downward pressure on the share of income flowing to the richest households. We can explain roughly between 18 and 30% of the decline in manufacturing and just under ten percent of the rise in top-ten inequality by the 1950s to 1990s decline in procurement spending. We thus conclude that Cold War procurement—while under-studied in the modern, quantitative economics literature on inequality—played a major role in sustaining tight labor markets for low-skill workers in the decades immediately after World War II and creating political coalitions in support of hawkish foreign policy and military expenditure. Figure 8 panel (a) shows that manufacturing employment is highly sensitive to defense spending, consistent with our state-year evidence. As is well known, manufacturing booms during World War II, but, less discussed, plummets in the years between World War II and Korea. After bouncing back during Korea, it slowly declines alongside the declining defense share of GDP until both series experience an uptick during Vietnam. Overall, the relationship remains highly significant even after taking out a linear time trend and dropping the World War II period.
