WebbIn Shapley’s [ 2] work, the balanced condition is defined for the coalitional vector system , which specifies the weight of each participant in each coalition. For the core to be nonempty, the coalitional vectors system must exist for the game to be -balanced. Later, Hwang [ 3] treats the Cartesian product of these NTU games as a multiple-NTU game. Webbψ(N,v) is a vector of payoffs to each agent, explaining how they divide the payoff of the grand coalition ψi(N,v) is i’s payoff shorthand: x∈ RN: payoffs to each agent in N, when …

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.
