AbstractWe analyze institutional solutions to international cooperation when actors have heterogeneous preferences over the desirability of the action and split into supporters and opponents, all of whom can spend resources toward their preferred outcome. We study how actors can communicate their preferences through voting when they are not bound either by their own vote or the outcome of the collective vote. We identify two organizational types with endogenous coercive enforcement and find that neither is unambiguously preferable. Like the solutions to the traditional Prisoners' Dilemma these forms require long shadows of the future to sustain. We then show that cooperation can be sustained through a noncoercive organization where actors delegate execution to an agent. Even though this institution is costlier, it does not require any expertise by the agent and is independent of the shadow of the future, and thus is implementable when the others are not.

Rosato (2003) claims to have discredited democratic peace theories. However, the methodological approach adopted by the study cannot reliably generate the conclusions espoused by the author. Rosato seems to misunderstand the probabilistic nature of most arguments about democratic peace and ignores issues that an appropriate research design should account for. Further, the study's use of case studies and data sets without attention to selection-bias produces examples that actually support theories it seeks to undermine. These problems place in doubt the article's findings.
