The aim of this paper is to discuss the role played by international institutions in achieving effective International Environmental Agreements. We emphasise the strategic nature of environmental negotiations and use a game theoretic model of coalitional bargaining to illustrate the main issues....

Since the seminal paper of Hoffman et al. (1994), an entitlement effect is believed to exist in the Ultimatum Game, in the sense that proposers who have earned their role (as opposed to having it randomly allocated) offer a smaller share of the pie to their matched responder. The entitlement...

We study whether the Coase conjecture holds in a model of bargaining during conflict due to Powell and Fearon. Two players, A and B, contest a divisible resource. At any time during the conflict, they can make a binding agreement to share the resource. The conflict continues until they make an...

We experimentally study behavior in a finitely repeated coalition formation game played in real time. Subjects interact in groups of three, bargaining over the distribution of payments which occur at regular time intervals. During a given interval, payments occur if and only if a majority is in...

Nash's characterization of his famous bargaining solution has long faced the objection of being welfarist: a bargaining situation is captured by a utility possibility set and a utility vector prevailing in case of disagreement, with no further information regarding the underlying economic...
