WebIntuitively, the Shapley value can be understood as a weighted average of a player’s marginal contributions to every possible subset of players. Let be the set of per-mutations of the integers up to N, and given ˇ 2 let S i;ˇ= fj: ˇ(j) The Shapley value not only has desirable properties, it is also the only payment rule satisfying some subset of these properties. For example, it is the only payment rule satisfying the four properties of Efficiency, Symmetry, Linearity and Null player. See for more characterizations.
