Stable coalition structures with a unidimensional set of alternatives
Article Abstract:
Amodel analyzing coalition structures in which members are allowed free entry and free mobility is presented. For example, alternatives available to coalitions are determined, for the most part, by the individuals composing the coalition. Successful coalitions, more so than non-successful ones, have a greater choice of alternatives available to its members. The model is also compared to Nash equilibria.

Equilibrium binding agreements: A comment
Article Abstract:
Ray and Vohra define a concept of an equilibrium between coalitions to construct their Equilibrium Binding Agreements and prove its existence for any coalition structure. The result crucially depends on the quasi-concavity of the utility functions, which in turn depends on the type of mixed strategies used by the coalitions.

Mixed equilibria are unstable in games of strategic complements
Article Abstract:
The study presents that properly mixed-strategy Nash equilibria (PMNE) are bad prediction in games of strict strategic complements and they are unstable under a broad class of learning dynamics. The pricing game described is under quite natural assumptions a game of strict strategic complements.
