of the first models where restrictions in cooperation are considered is the one of games with coalition structure. In … such games the player set is partitioned into unions and players can only cooperate within their own union. Owen introduced … a value for games with coalition structure under the assumption that also the unions can cooperate among them. Winter …

In this paper, the … conference game to establish later which effects a union stable system has on certain desirable properties of these games. Using …

A (single-valued) solution for TU-games assigns a payoff … consider the class of non-negative additive games with an acyclic permission structure. This class generalizes the so …-called peer group games being non-negative additive games on a permission tree. We provide a polynomial time algorithm for …
