This paper proposes a theoretical explanation for the incremental integration path of Europe until the Monetary Union … time. The dynamic partition function game suggests that the presence of externalities across coalitions affects the timing … of admission of different players, the equilibrium coalition structure, and the equilibrium length of the admission game …

This paper studies coalition formation among individuals who differ in productivity. The output of a coalition is … determined by the sum of productivities if the coalition exceeds a minimal threshold of members. We consider competitive … societies in which the surplus of a coalition is split according to productivity and egalitarian societies in which coalitions …

sharing scheme is particularly powerful for economic problems that are characterized by positive externalities from coalition …We propose a class of sharing schemes for the distribution of the gains from cooperation for coalition games with … externalities. In the context of the partition function, it is shown that any member of this class of sharing schemes leads to the …

This chapter surveys recent models of coalition and network formation in a unified framework. Comparisons are drawn … among various procedures of network and coalition formation, involving simultaneous and sequential moves. The survey also … discussion of efficient network and coalition formation procedures and directions for future research. …
