Ideology, Institutions, Power, and Militarized Disputes

This chapter examines if and how intergovernmental organization (IGO) memberships shape participation in militarized interstate disputes. Theorists have argued that IGOs solve informational problems, socialize states, or constitute democratic communities that prevent a resort to violence. The distributive ideological approach suggests that IGOs institutionalize ideologically cohesive coalitions that ameliorate conflicts with insiders but can exacerbate conflict with outsiders. The effect of IGOs on militarized disputes should be present only if the distributional stakes have global ideological implications as opposed to when disputes are purely over particularistic stakes, such as territory. Regression analyses support this insight. Both ideological differences and IGO membership patterns affect dispute participation in dyads that include a major power but not among neighboring states or states involved in a territorial dispute. One implication is that IGO memberships affect the distribution of militarized disputes, but it is unclear whether IGOs in the aggregate reduce militarized conflict.
