Bayesian equilibria are characterized by means of consistency and one-person rationality in combination with non-emptiness or converse consistency. Moreover, strong and coalition-proof Bayesian equilibria of extended Bayesian games are introduced and it is seen that these notions can be...

In this paper we study the endogenous formation of cooperation structures or communication graphs between players in a superadditive TU game. For each cooperation structure that is formed, the payoffs to the players are determined by an exogenously given solution. We model the process of...

This paper considers a refinement of equilibria for multicriteria games based on the perfectness concept of Selten (1975). Existence of perfect equilibrium points is shown and several characterizations are provided. Furthermore, contrary to the result for equilibria for multicriteria games, an...

Environmental degradation is increasingly causing cross-border displacement of people, but countries have formed no treaties to facilitate collaboration on the issue. When is such collaboration feasible, and how should environmental displacement treaties be designed? We present a game-theoretic...

Multilateral funding for global environmental protection, such as biodiversity conservation, requires donor participation. When are donors willing to participate? We examine a game-theoretic model of multilateral funding for environmental projects in developing countries. Donors must first...

In this paper the well-known minimax theorems of Wald, Ville and Von Neumann are generalized under weaker topological conditions on the payoff function f and/or extended to the larger set of the Borel probability measures instead of the set of mixed strategies.

In this paper we discuss the level set method of Joó and how to use it to give an elementary proof of the well-known Sion’s minimax result. Although this proof technique is initiated by Joó and based on the inter-section of upper level sets and a clever use of the topological notion...

In democratic societies, citizens can hold their government politically accountable for the consequences of international cooperation. Can democratic accountability shape international cooperation under strategic interdependence, and if so, to what effect? I show formally that citizens can endow...
