Abstract:Curiel, Potters, Prasad, Tijs and Veltman (1993) introduced component additive games which are cooperative TU games that arise by imposing an order on the player set. Further, they introduced the beta-rule which allocates a core element to each component additive game.In this paper we consider the class of restricted component additive games that arise by restricting the attention to head-tail coalitions. The extreme points of the corresponding restricted core are characterized. Further, it is shown that the beta-rule is the barycenter of the corresponding restricted core and that the beta-rule coincides with the nucleolus of this restricted game.
