This paper studies the problem of endogenous coalition formation in contests: how players organize themselves in groups … settings. Efficiency gains are said to be generated if any coalition experiences increasing marginal returns with aggregate … a sequential coalition formation game for an arbitrary number of symmetric players and exogenous effort.

We study coalition formation problems with general externalities. We prove that if expectations are not prudent a … stable coalitions structure can fail to exist. Under prudent expectations a stable coalition structure exists if the set of … admissible coalitions is single-lapping. This assumption also guarantees the existence of a stable and efficient coalition …

We examine the welfare properties, coalition-proofness and order-theoretical structure of the set of Nash equilibria in … games, we prove the equivalence among the set of Nash equilibria, the set of coalition-proof Nash equilibria under strong … prove that the fixed points of some "extremal" selections from the joint best reply correspondence are both coalition …

In this paper we study the formation of coalition structures in situations described by a cooperative game. Players … choose independently which coalition they want to join. The payoffs to the players are determined by an allocation rule on … the underlying game and the coalition structure that results from the strategies of the players according to some …
