The motivation is that the standard IAM literature aggregates welfare into a global number, obscuring the distributional structure that determines political feasibility. Without knowing which countries gain and lose, and through which channels, it is impossible to understand why international cooperation is so difficult or which club structures can sustain themselves.</p>
