Shapley value for TU-games with multiple memberships and externalities

Denis Sokolov

Mathematical Social Sciences, 2022, vol. 119, issue C, 76-90

Abstract: In this paper, we introduce a new form, the clique function form (CQFF), of TU-games that allows for multiple memberships and explicit externalities. The new notion is based on a graphical representation of the connections between agents in a game. We treat as coalitions only fully connected sub-graphs (i.e., maximal cliques). Following Myerson (1977a) we adapt the well-known efficiency, symmetry, and linearity axioms to the new setting and obtain a unique value for superadditive CQFF games.
