Stability analysis for international environmental agreements with social externalities

In this thesis we study the stability of an International Environmental Agreements, in which a positive Social Externalities affect the pay-offs of the players when they make an agreement. We consider both cases of static and dynamic games, and we divide players (countries), into two homogeneous groups, developed and developing countries. We solve both stages of this kind of games: The membership game, in which players choose whether to sign or not the coalition; and the emission game, in which signatories select emissions maximazing the joint welfare, while the non signatories maximize their own welfare.
