Replication Data for Alliances and the High Politics of International Trade

What is the role of trade policy in military alliances? We analyze and test a game- theoretic model of economic and security cooperation in which allies hold different in- terests across the security and commercial aspects of the relationship. In equilibrium, allies with little market power who are valuable politically to larger states engage in suboptimal protectionism, since their allies’ threats of retaliation are incredible. Sta- ble cooperation emerges in the form of unretaliated protection rather than mutually low trade barriers. We test the model’s implications against a dyadic dataset of antidumping petitions from 1980-2013 and find that larger allies are are more likely to tolerate pro- tectionism by smaller allies by denying domestic petitions to retaliate against dumping measures by the latter.
