The position value and the structures of graphs. (English) Zbl 1429.91027

Summary: The position value is an allocation rule based on the Shapley value of the link game from the original communication situation, in which cooperation is restricted by a graph. In the link games, feasible coalitions are connected but their structures are ignored. We introduce structure functions to describe the structures of connected sets, and generalize the link game and the position value to the setting with local structures. We modify an axiomatic characterization for the position value by M. Slikker [Int. J. Game Theory 33, No. 4, 505–514 (2005; Zbl 1091.91006); with A. van den Nouweland, Math. Soc. Sci. 64, No. 3, 266–271 (2012; Zbl 1260.90045)] to the generalized position value by component efficiency and balanced link contributions on local structures.
