. Do pure indivisibilities prevent core equivalence? Core equivalence theorem in an atomless economy with purely … agents, the core coincides with the set of Walras 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 …

core coincides with the set of cost-minimized Walras allocations. Because of the indivisibility, the preference …, all agents satisfy both the preference maximization and the cost minimization. -- Indivisible commodities ; Strong core … ; Cost-minimized Walras equilibrium ; Core equivalence …

. We prove that the strong core coincides with the set of cost-minimized Walras allocations which satisfy both the … preference maximization and the cost minimization under the same price vector. -- Indivisible commodities ; Core equivalence … ; Strong core ; Cost-minimized Walras equilibrium …

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 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 … theorems of Shapley and Shubik (1975) are included as special cases. -- Market Games ; Competitive Payoffs ; Core …

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 … results on non-cooperative foundations of cooperative games. -- Inner Core ; Asymmetric Nash Bargaining Solution ; Competitive …
