paper analyzes Harsanyi power solutions for cooperative games in which partial cooperation is based on union stable systems …. These structures contain as particular cases the widely studied communication graph games and permission structures, among …

-player agent game model, both being generalizations of the Shapley value for TU-games. The first is the agent-Shapley value and … the player- and agent-Shapley values we apply them to airport games and voting games. …

A (point-valued) solution for cooperative games with transferable utility, or simply TU-games, assigns a payoff vector …

We consider the problem of axiomatizing the Shapley value on the class of assignment games. We first show that several … axiomatizations of the Shapley value on the class of all TU-games do not characterize this solution on the class of assignment games … on the class of assignment games. Moreover, these two axioms have a natural interpretation for assignment games …

various models of games with restricted cooperation can be found. In those models, instead of allowing for all subsets of the … unique directed path from the top player to this player. We introduce a new solution for these games based on the idea of the … Average Tree value for cycle-free communication graph games. We provide two axiomatizations for this new value and compare it …

This discussion paper resulted in a publication in 'Games and Economic Behavior', 2012, 76, 344-348. <P> Three well …-known solutions for cooperative TU-games are the Shapley value, the Banzhaf value and the equal division solution. In the literature …
