Nonsymmetric values under Hart-Mass-Colell consistency

Let f be a single valued solution for cooperative TU games that satisfies inessential game property, efficiency, Hart Mas-Colell consistency and for two person games is strictly monotonic and individually unbounded. Then there exists a family of strictly increasing functions associated with players that completely determines f. For two person games, both players have equal differences between their functions at the solution point and at the values of characteristic function of their singletons. This solution for two person games is uniquely extended to n person games due to consistency and efficiency. The extension uses the potential with respect to the family of functions and generalizes potentials introduced by Hart and Mas Colell 6]. The weighted Shapley values, the proportional value described by Ortmann 11], and new values generated by power functions are among these solutions.
