An Axiomatization of Harsanyi's Nontransferable Utility Solution
Sergiu Hart
Abstract
A set of axioms is proposed, which uniquely characterize the
Harsanyi [1963] soluton for nontransferable utility (NTU) games.
These axioms appear formally identical to those of Aumann [1985]
for the Shapley ("λtransfer")
NTU value; the difference
lies in the range of the two solutions.
Further characterizations and comparisons between these two
solution concepts are then presented.
