The relation between internal and core stable solutions is … exist. But this class of games is more restricted than the one for which only ?-core solutions exist. The argument is first …

define a transferable utility game whose core defines fair judgments. We show that weighted Shapley values define fair …

The lack of stability in some matching problems suggests that alternative solution concepts to the core might be a step … roommate problems with strict preferences. This solution, which always exists, either gives the matchings in the core or … predicts other matchings when the core is empty. Furthermore, it satisfies the interesting property of outer stability. We also …

This paper introduces a core concept, called the γ-core, in the primitive framework of a strategic game. For a certain … coalition forms if the γ-core is nonempty. This is a weaker sufficient condition than the previous such condition (Maskin (2003 …, Theorem 4)). As an application of this result, it is shown that the γ- core of an oligopolistic market is nonempty and thus …

This paper provides a general overview of the literature on the core of an exchange economy with asymetric information …. Incentive compatibility is emphasized in studying core concepts at the ex ante and the interim stage.The analysis includes … issues of non emptiness of the core as wellas core convergence to price equilibrium allocations. …

We show that in large finite economies, core allocations can be approximately decentralized as Nash (rather than Walras …) equilibrium. We argue that this excrcise is an essential complement to asymptotic core equivalence results, because it implies … precisely the interpretation of asymptotic core convergence, namely the emergence of price taking. …
