A maximal domain for the existence of strategy-proof rules.

The writers demonstrate that the maximal domain, including single-peaked preferences for strategy-proofness, efficiency, and symmetry, is unique and slightly larger than the single-peaked domain. They argue that this finding shows that the assumption of single-peakedness essentially cannot be weaken...

Sumario:The writers demonstrate that the maximal domain, including single-peaked preferences for strategy-proofness, efficiency, and symmetry, is unique and slightly larger than the single-peaked domain. They argue that this finding shows that the assumption of single-peakedness essentially cannot be weakened if one insists on strategy-proofness, together with the distributional requirement of symmetry and the optimality requirement of efficiency. They contend that this result can be alternatively understood as a general impossibility theorem.
