摘要:
We ask how the best known mechanisms for solving cost sharing problems with homogeneous cost functions-the value, proportional, and serial mechanisms-should be extended to arbitrary problems. We propose the Ordinality axiom, which requires that cost shares should be invariant under (essentially) all increasing transformations of the measuring scales. Following the value approach first, we present an axiomatization of the Shapley-Shubik rule based on Ordinality. Next, we define and axiomatize two extensions of the serial mechanism which, contrary to the Friedman-Moulin rule, are ordinal. Finally, we note that the Aumann-Shapley extension of the proportional mechanism is not ordinal. We propose and defend an alternative proportional extension which does satisfy Ordinality.
