This contribution investigates the link between welfare policies and domestic terrorism for 15 Western European countries during 1984-2003. We argue that welfare policies improve national social and socio-economic conditions and thus increase the opportunity costs of terrorism. We investigate...

Does U.S. military aid make the United States safer? To answer this question, we collect data on 173 countries between 1968 and 2014. Exploiting quasi-random variation in the global patterns of U.S. military aid, our paper is the first to provide causal estimates of the effect of U.S. military...
