This chapter surveys a sizable and growing literature on coalition formation. We refer to theories in which one or more … payoffs at each date according to the coalition structure prevailing at the time. We use this model to nest two broad … approaches to coalition formation, one based on cooperative game theory, the other based on noncooperative bargaining. Three …

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 …

This paper studies coalition formation and payoff division in apex games under the following assumptions: first, payoff … division can only be agreed upon after the coalition has formed (two-stage bargaining); second, negotiations in the coalition … can break down, in which case a new coalition may be formed (reversible coalitions).In contrast with the results of other …

the efficient coalition structure is stable in terms of the coalition formation theory. It is assumed that coalitions can … coalitions) and a coalition may deviate if and only if it stands to gain from it. It is then shown that subsequent to a deviation … by a coalition, the nonmembers will have incentives to break apart into singletons, as is assumed in the definition of …
