IO mediation of interstate conflicts: Moving beyond the global versus regional dichotomy

Abstract

Regional and global intergovernmental organizations have grown both in number and scope, yet their role and effectiveness as conflict managers is not fully understood. Previous research efforts tend to categorize organizations solely by the scope of their membership, which obscures important sources of variation in institutional design at both the regional and global levels. International organizations will be more successful conflict managers if they are highly institutionalized, if they have members with homogeneous preferences, and if they have more established democratic members. These hypotheses are evaluated with data on territorial (1816-2001), maritime (1900-2001), and river (1900-2001) claims from the Issue Correlates of War (ICOW) project in the Western Hemisphere, Europe, and the Middle East. Empirical analysis suggests that international organizations are more likely to help disputing parties reach an agreement if they have more democratic members, if they are highly institutionalized, and when they use binding management techniques. © 2008 Sage Publications.
