In this paper, we characterize the class of games for which the core coincides with the core cover (compromise stable games). Moreover, we will develop an easy explicit formula for the nucleolus for this class of games, using an approach based on bankruptcy problems. Also, the class of convex...

This paper revisits the Alexia value, a recent solution concept for cooperative transferable utility games. We introduce the dual Alexia value and show that it coincides with the Alexia value for several classes of games. We demonstrate the importance of the notion of compromise stability for...

The core cover of a TU-game is a superset of the core and equals the convex hull of its larginal vectors. A larginal vector corresponds to an order of the players and describes the efficient payoff vector giving the first players in the order their utopia demand as long as it is still possible...
