On several classes of n-person NTU games that have at least one Shapley NTU value, Aumann characterized this solution … independence of IIA is an open problem. We show that for n = 2 the first five axioms already characterize the Shapley NTU value …

In 1985 Aumann axiomatized the Shapley NTU value by non-emptiness, efficiency, unanimity, scale covariance, conditional …
