Military expenditure and economic growth, 1960–2014

This article compares results of our 2015 study of the effect of military expenditure on economic growth, 1988–2010, with results using an additional 28 years of data provided in the newly revised and extended SIPRI dataset, 1960–2014. When the additional data points are added, we find no substantive differences and confirm the statistically significant negative effect of military expenditure on growth reported in our prior research. Using the same estimation process, there is no evidence of a structural break in the time series. Considering nonlinearity and heterogeneity, the estimates using the new data for ninety-seven countries are remarkably consistent with the earlier results and, overall, are very similar in sign and statistical significance, and many of the coefficients are larger (more adverse) than before. The new data provide valuable extra information and support for the original findings.
