The coarse and fine core, as originally defined by Wilson (1978), correspond to two polar …An appropriate (interim) notion of the core for an economy with incomplete information depends on the amount of … credible core, which incorporates incentive compatibility constraints, and is based on the idea that a coalition can coordinate …

A core allocation of a complete information economy can be characterized as one that would not be unanimously rejected … of such voting games, this approach makes it possible to derive core concepts in which the transmission of information … among members of a coalition is endogenous. Our results lend support to the credible core of Dutta and Vohra (2003) and the …

We investigate the relationship between certain subsets of the core for TU market games and competitive payoff vectors … and Shubik (1975). They remark already that their result can be extended to any closed convex subset of the core, but they …

We consider the inner core as a solution concept for cooperative games with non- transferable utility (NTU) and its … subsets of the inner core for NTU market games and competitive payoff vectors of markets linked to the NTU market game. This … large class of closed subsets of the inner core: Given an NTU market game we construct a market depending on a given closed …

We investigate the relationship between the inner core and asymmetric Nash bargaining solutions for n-person bargaining … positive vectors of weights coincides with the inner core if all points in the underlying bargaining set are strictly positive …

The seminal contribution of Debreu-Scarf (1963) connects the two concepts of core and competitive equilibrium in … exchange economies. In effect, their core-equilibrium equivalence result states that, when the set of economic agents is … replicated, the set of core allocations of the replica economy shrinks to the set of competitive allocations.

We show that this equivalence holds only in an atomless … economy by giving two examples of the sequence of replica economies such that in any replica economy, there exists a core …
