Intergovernmental Organizations and the Kantian Peace

Abstract

The authors use network analysis to argue that the main contribution of intergovernmental organizations (IGOs) to international stability is not necessarily their direct and individual impact, because generally IGOs are institutionally weak. Rather, membership of IGOs creates network ties between states, allowing them, either individually or collectively, to intervene more effectively in latent conflicts. The IGO network also provides direct and indirect communication channels, where indirect links can act as partial substitutes for direct diplomatic ties. Empirically, the authors apply these ideas to the extensive network of international linkages created in the post—World War II period. They demonstrate that indirect links do indeed matter and that they substitute for more direct diplomatic ties. Furthermore, these effects are not limited to ties created by IGOs with specific security functions.
