We prove the non-emptiness of the core of an NTU game satisfying a condition of payoff-dependent balancedness, based on … transfer rate mappings. We also define a new equilibrium condition on transfer rates and we prove the existence of core payoff … vectors satisfying this condition. The additional requirement of transfer rate equilibrium refines the core concept and allows …

(interim) incentive compatible coarse core of the matching game are both non-empty. …We consider two-sided matching markets in which agents have private information on a state of nature which determines … the agents' utilities of matching. Monetary transfers are allowed and utility functions are quasi-linear. The model thus …

) coalitional equilibrium, describe a (cooperative) partition form game. A coalition is core-stable if the core of a suitable …

In a commonvalueauction in which the information partitions of the bidders are connected, all rings are core … form, in spite of the underlying strategic externalities. A ring is core-stable if the core of this characteristic function … core-stable. …

Different kinds of asymmetries between players can occur in core allocations, in that case the stability of the concept … is questioned. One remedy consists in selecting robust core allocations. We review, in this note, results that all select … core allocations in NTU games with different concepts of robustness. Within a unified approach, we deduce the existence of …
