A note on the core of TU-cooperative games with multiple membership externalities (Q2346946)

Summary: A generalization of transferable utility cooperative games from the functional forms introduced \textit{J. von Neumann} and \textit{O. Morgenstern} [Theory of games and economic behavior. Princeton, New Jersey: Princeton University Press (1944; Zbl 0063.05930)] and \textit{R. M. Thrall} and \textit{W. F. Lucas} [Nav. Res. Logist. Q. 10, 281--298 (1963; Zbl 0229.90056)] is proposed to allow for multiple membership. The definition of the core is adapted analogously and the possibilities for the cross-cutting of contractual arrangements are illustrated and discussed.
