Abstract

The purpose of this paper is to offer an empirical reappraisal of the relationship between military alliances and international trade, using "best practices" in gravity modeling. Specifically, we address three questions. First, do military allies trade more with one another than they do with other countries? Second, is accession to an alliance associated with an increase in trade between "new" and “old” members? Third, do allies more or less with their adversaries than with other countries? Focusing on the members of the North Atlantic Treaty Organization (NATO), we find that alliance accession is indeed associated with increased levels of trade, but overall, allies do not trade more with one another than they do with other countries (including their adversaries). Our research thus provides only partial support for some of the earlier studies that assessed the Effects of military alliances on international trade patterns.
