We consider a hedonic coalition formation game in which at each possible partition any new coalition can decide the … can decide whether or not to support a coalition's move: they know which future partition, and hence payoffs, will be … probabilities that are always above some e > 0, then there is a behavior profile in which no coalition has a profitable one …

coalition is given by the sum of the valuations for all other players belonging to it. So far, non-cooperative hedonic games …

We investigate the computational complexity of several decision problems in hedonic coalition formation games and … either core stability or strict core stability is under consideration, the existence problem of a stable coalition structure … stable coalition structure and of an individually stable coalition structure turn out to be NP-complete in the strong sense …

In this note we show that no solution to coalition formation games can satisfy a set of axioms that we propose as … reasonable. Our result points out that solutions to the coalition formation cannot be interpreted as predictions of what would be … resting points for a game in the way stable coalition structures are usually interpreted …

This paper introduces a model of coalition formation with claims. It assumes that agents have claims over the outputs … coalition formation emerges. Using resource monotonicity and consistency, we characterize the continuous rationing rules that …
