This paper studies multilateral negotiations among n players in an environment where there are externalities and where … value of players and the Markov state transition probability that encodes the path of coalition formation. The existence of … equilibria is established, and Pareto efficiency is guaranteed if the grand coalition is efficient, despite the existence of …

We study assignment problems with externalities where agents have expectations about the reactions of other agents to …

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 …

Consider an environment with widespread externalities, and suppose that binding agreements can be written. We study … coalition formation in such a setting. Our analysis proceeds by defining on a partition function an extensive form bargaining … concerned with the characterisation of equilibrium coalition structures. We develop an algorithm that generates (under certain …
