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 …

We study the implementation of social choice rules in environments with externalities. We prove the impossibility of …

We consider competitive … societies in which the surplus of a coalition is split according to productivity and egalitarian societies in which coalitions …
