The Structure of International Cooperation Networks

• In Event: Understanding the Ties That Bind States: Institutions, Networks, and Community

Abstract

How do network relationships among states produce coalitions that shape international cooperation? States interact on multiple dimensions and form ties based on common interests and shared values. Much of the quantitative research in international relations examines the dyadic relationships such as alliances, trade agreements, and diplomatic ties. Each of these ties represents an outcome that is part of a larger system of relationships connecting states. This paper will identify latent groups in network analysis of alliances, trade agreements, and diplomatic ties. States that belong to the same group exhibit similar patterns of forming ties. We then assess how these groups influence multilateral cooperation. First we examine votes on several key UN resolutions, which measure specific acts of cooperation. Then we look at membership in international organizations as a more general form of cooperation. Our findings reveal the extent that latent groups based on security ties, trade ties, or diplomacy predict multilateral cooperation. By comparing with the predictions based on dyadic ties alone, our analysis demonstrates that latent groups form an important variable for understanding when states work together.
