In an example with two objects and four bidders, some of which have superadditive values, we characterize the equilibria of a simultaneous ascending auction and compare the revenue and efficiency generated with ones generated by the sequential , the one-shot simultaneous, and the...

Correlated equilibria and communication equilibria are useful notions to understand the strategic effects of information and communication. Between these two models, a protocol generates information through communication. We define a secure protocol as a protocol from which no individual may...

The authors develop a two-stage negotiation model to study the impact of costly inspections on both the coalition formation outcome and the per-member payoffs.

This paper provides a methodology to study coalition formation problems with externalities and heterogeneous players, whensome subset of the players can act as "coalition developers" over time. The framework provided here allows to explicitly predict the timing of admission to coalitions, the...

This paper deals with N-Person sequential bargaining games with complete information (perfect or almost perfect information). For N-person sequential bargaining games, uniqueness of the SPE has been obtained by allowing the players to exit with partial agreements.

This paper considers a model of oligopolistic competition and locational choice that incorporates the notion of regional industrial systems. Firms play a non cooperative game where the strategy set of firms is given by a set of existing industrial districts. Each firm is distinguished by its...
