Political, economic, and social consequences of foreign military intervention

Abstract

Foreign military intervention is one of the most common types of interstate military force used over recent decades. As war's costliness increases and the efficacy of economic sanctions and other foreign policy tools is increasingly questioned, it may become even more prevalent. Unfortunately, the field of international relations has little systematic understanding of the types of impacts such military ventures can have on target states in the developing world. In PCSE AR1 regressions of 106 developing countries from 1960 to 2002, we find that large scale foreign military interventions, which have over 1000 intervening troops, do not leave a significant imprint on governing institutions, economic growth rates, or physical quality of life in developing democracies. The same cannot be said for non-democratic states in the developing world. Hostile interventions can help to democratize non-democratic targets, while rival interventions lay the groundwork for long- term economic growth.
