Closed kernel systems of the coalition matrix turn out to correspond to cones of games on which the core correspondence …

We decompose core CPI and the food and energy CPI measures into permanent and transitory components using a correlated … unobserved components model, to examine the behavior of core CPI when subject to shocks and to examine the claim that core CPI … captures the persistent part of headline CPI. We find that the permanent component of core CPI is more volatile than core CPI …

veto power if all coalitions not containing her are worthless. We examine and characterize the core for each one of these … "veto games". Moreover, we show the equivalence of the core and the bargaining set. Our work extends the clan games and big …

all men acceptable, Sasaki and Toda (1992) characterize the core by anonymity, Pareto optimality, consistency, and … by characterizing the core on the domain of no odd rings roommate markets by individual rationality, anonymity, Pareto …

Finding a solution concept is one of the central problems in cooperative game theory, and the notion of core is the … coalitions can form, so that classical TU-games cannot be used. An interesting case is when possible coalitions are defined … through a partial ordering of the players (or hierarchy). Then feasible coalitions correspond to teams of players, that is …

important notion in cooperative game theory is the core of the game, as it contains the rational imputations for players. We … propose two definitions for the core of a multichoice game, the first one is called the precore and is a direct generalization … normalization at each level, causing the core to be a convex compact set. We study its properties, introducing balancedness and …

two-sided related market, the midpoint between the buyers-optimal core allocation and the sellers-optimal core allocation … solution belongs to the core of the one-sided market and it is pairwise-monotonic. Copyright Springer-Verlag 2009 …

In cooperative games, the core is the most popular solution concept, and its properties are well known. In the … classical setting of cooperative games, it is generally assumed that all coalitions can form, i.e., they are all feasible. In … many situations, this assumption is too strong and one has to deal with some unfeasible coalitions. Defining a game on a …
