stable solutions of a multiple partners matching game in two different ways and perform a study on the core of the … the existence of a stable solution and the non-emptiness of the core, which holds in the other models with payments, is no …

-firm-buyer games have non-empty core. We show that for these games the core coincides with the classical bargaining set (Davis and …

concentrate on one solution concept: the core. First we examine the basic model and then we consider several variations that are …

shown that the core of a TU-game coincides with the core of the corresponding minimal rights game. Moreover, the paper … introduces the notion of the k-core cover as an extension of the core cover. The k-core cover of a TU-game consists of all … minimal rights game. It is shown that the core of a TU-game with player set N coincides with the L|N |/2-̦core cover …

the unique welfare distribution that is core-stable and satisfies the condition that no agent gets a utility payoff above … has an increasing benefit function (no externalities) then every weighted hierarchical solution is core-stable. In case of …

We study linearly weighted versions of the least core and the (pre)nucleolus and investigatethe reduction possibilities … dual game. Our main results imply, for example, that if the core of the game is not empty, all dually inessential … core and the per-capita (pre)nucleolus from the dual game.
