Dynamics of Change in International Organizations
States face several options when intent on changing an international organization: they can either reform it or create a successor that assumes all or part of the prior organization’s functions–a practice known as institutional succession. Reform and succession are equally efficient mechanisms of institutional change, yet addressing different negotiating hurdles. While succession allows reformers to sidestep veto players on whom reform often trips, unlike reform, succession suffers from scale suboptimality since not every existing member may join the successor institution. Contingent on which negotiation obstacle prevails, reform is preferred to succession or vice versa. We provide a game-theoretic foundation to this proposition, advance a computational solution, and illustrate it with empirical examples.
