Does Military Spending Crowd Out Social Welfare Expenditures? Evidence from a Panel of OECD Countries.

This article examines the relationship between defense and social welfare expenditures using a panel of 29 OECD countries from 1988 to 2005. It is quite difficult to take into account the simultaneous channels empirically through which the eventual allocation of defense and welfare spending is determined for the guns-and-butter argument. Taking advantage of our collected panel data-set, the panel generalized method of moments method is adopted to control the country-specific heterogeneity and to mitigate the potential simultaneity problem. The main finding of this article suggests a positive trade-off between military spending and two types of social welfare expenditures (i.e. education and health spending). One of the reasons may be that the OECD countries are more supportive of the social welfare programs; therefore, when the military spending is increased (e.g. military personnel and conscripts), the government may raise the health and education spending as well.
