We extend the work on coalition formation in global pollution control by allowing for multiple coalitions. Equilibrium coalitions are derived under different "rules of the game" and compared with each other. We consider internal & external equilibria and equilibrium binding agreements in the...

In this paper we analyze how ratification uncertainty impacts the optimal terms of international environmental agreements (IEAs). We relax the frequent assumption of countries as unitary actors by modeling the ratification stage through uncertain preferences of a ratifying agent (e.g. the...

We augment the standard cartel formation game from non-cooperative coalition theory, often applied in the context of international environmental agreements on climate change, with the possibility that singletons support coalition formation without becoming coalition members themselves. Rather,...

In a Nash equilibrium of voluntary participation games in international environmental agreements, the optimal surplus sharing rules, proposed by Eyckmans and Finus (2004) and Weikard (2009), incentivize more countries to participate in the agreements. We examine how robust this desirability of...

We reassess the well-known “narrow-but-deep” versus “broad-but-shallow” trade-off in international environmental agreements (IEAs), taking into account the principal-agent relationship induced by the hierarchical structure of international policy. To this end, we expand the modest...

We examine the formation of hub-and-spoke and multilateral green technology international agreements. Green R&D provision produces two types of positive externalities, a global public good (i.e., reduction of carbon dioxide emissions) and spillovers in technology agreements. We utilize the...
