This paper investigates core stability of cooperative, TU games via a fuzzy extension of the totally balanced cover of … a TU game. The stability of the core of the fuzzy extension of a game, the concave extension, is shown to reflect the … core stability of the original game and vice versa. Stability of the core is then shown to be equivalent to the existence …

notion of an interval core has been coined and proposed as a solution concept for interval-valued games. In this paper we … will present a general mathematical programming algorithm which can be applied to find an element in the interval core. As … demonstrate how interval core elements can be computed. Also, we reveal that pitfalls exist if interval core elements are computed …

utility (TU) game from the viewpoint of general equilibrium theory. For any given game, we construct a competitive exchange … coalition production economy corresponding to the game. First, it is shown that the full core of a TU game is not empty if and … only if the completion of the game is balanced. The full core is defined free of any particular coalition structure and the …

We are concerned with the problem of core membership testing for hedonic coalition formation games, which is to decide … whether a certain coalition structure belongs to the core of a given game. We show that this problem is co-NP complete when …

. 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 …

"The common-property literature has often focused on the question of efficiency. Here we consider distributional issues instead. How should the benefits of the commons (say, a fishery) be distributed? We approach the question from the viewpoint of ownership rather than income redistribution. "A...

"Institutional approaches to social dilemmas have so far focused on how to create incentive structures that channel individuals' behavior into socially desirable outcomes assuming that everyone is selfish. However, the presumption of universal selfishness is not only empirically invalid but may...
