Using an updated version of the CWS model (introduced by Eyckmans and Tulkens in Resource and Energy Economics 2003), this paper intends to evaluate with numbers the respective merits of two competing notions of coalition stability in the standard global public goods model as customarily applied...

We study a setting where imitative players are matched into pairs to play a Prisoners' Dilemma game. A well know result in such setting is that under random matching cooperation vanishes for any interior initial condition. The novelty of this paper is that we add a certain correlation to the...

We study the emergence of norms of cooperation in experimental economies populated by strangers interacting indefinitely. Can these economies achieve full efficiency even without formal enforcement institutions? Which institutions for monitoring and enforcement facilitate cooperation? Finally,...

We provide a new equilibrium-refinement (a generalization of the Intuitive Criterion) for dynamic incomplete information games. We discuss the properties of this refinement in a class of games that includes sender-receiver games. We also provide applications (certain incomplete information games...

In Hart and Kurz (1983), stability and formation of coalition structures has been investigated in a noncooperative framework in which the strategy of each player is the coalition he wishes to join. However, given a strategy profile, the coalition structure formed is not unequivocally determined....

We show the existence of an upper bound for the number of blocks required to get from one imputation to another provided that accessibility holds. The bound depends only on the number of players in the TU game considered. For the class of games with non-empty cores this means that the core can...

The simplest and most common interpretation of a coalitional form game is that it pertains to a single interaction among the players. However, many if not most cooperative endeavors occur more than once or even repeatedly over time. In this paper we begin a systematic study of dynamic...

Most of the theoretical work on collusion and price wars assumes identical firms and an unchanging environment, assumptions which are at odds with what we know about most industries. Further that literature focuses on the impact of collusion on prices. Whether an industry can support collusion...

This paper is concerned with the question of defining the bargaining set, a cooperative game solution, when cooperation takes place in a dynamic setting. The focus is on dynamic cooperative games in which the players face (finite or infinite) sequences of exogenously specified TU-games and...
