Replication data for: Trading for Security: Military Alliances and Economic Agreements

A review of alliance treaties and diplomatic history suggests that under certain conditions states may tie together alliance agreements and economic agreements. When states explicitly link alliance agreements with economic cooperation, one would expect to see increased economic exchange coinciding with coordinated security policies.

This study evaluates whether the linking of economic and security agreements accounts for a positive relationship between alliances and trade among European states before WWII, and produces evidence in support of this argument. Trade among allies who have specified economic cooperation in their alliance agreements is higher than trade among non-allied states and higher than trade among allies who have not promised economic cooperation.
