We investigate the computational complexity of several decision problems in hedonic coalition formation games and demonstrate that attaining stability in such games remains NP-hard even when they are additive. Precisely, we prove that when either core stability or strict core stability is under...

This is a survey and discussion of work covering both formal game theory and experimental gaming prior to 1991. It is a useful preliminary introduction to the considerable change and emphasis which has taken place since that time where dynamics, learning, and local optimization have challenged...

The core is reformulated to incorporate the externality typical in strategic formgames. Any coalition of players may deviate by trying to commit to a profile of actionsdifferent from a status quo. The outsiders of the coalition may take a coordinatedmeasure, incentive-feasibly for themselves, to...

This paper associates a strategic n-person game with a given transferable utility game and studies its Nash equilibria. Strict equilibria in this model characterize those divisions of social surplus that can become conventions in the sense of Young (1993). It is shown that even in relatively...

A new feature pertaining to proposer's ability to implement offers is introduced in the extensive form bargaining mechanism studied in Chatterjee et. al. (1993). This mechanism is used to analyze two classes of coalitional games with transferable utility. One class is that of strictly...

I develop two related solution concepts, equilibrium coalitional behavior and credible equilibrium coalitional behavior, which capture foresight and impose the requirement that each coalition in a sequence of coalitional moves chooses optimally among all its available options. The model does not...

We study a model in which agents endowed with power compete for a divisible resource by forming coalitions with other agents. The coalition with the greatest power wins the resource and divides it among its members via proportional sharing. We conduct an economic experiment using this model to...

We examine the formation of multilateral, hub-and-spoke and bilateral international R&D strategic alliances (overlapping climate clubs) to reduce CO2 emissions. R&D provision in clubs produces two types of positive externalities: a global public good (i.e., reduction of CO2 emissions) and...
