Converging Military Spending and Its Fiscal Consequences

Worldwide military spending as a percentage of GDP in the years since the Global Crisis has been at nearly half its level during the Cold War. This column identifies three groups into which spending has been converging. It also shows that external threat levels are a factor in determining military spending, but only in developing economies. The results suggest a significant peace dividend from reducing internal conflicts, with a country that moves from the bottom 25% to the top 25% of developing countries on political stability and the absence of violence/terrorism likely to reduce military spending by about half a percentage point of GDP.
