Lindhal meets Condorcet?

Abstract

Although a Condorcet winner commands a majority in its favor, there is no guarantee of unanimity. In a Lindahl equilibrium, a suitably chosen system of personalized transfers and prices ensures unanimity, but there is no guarantee of a majority vote in its favor. Do Lindahl equilibria decentralize Condorcet winners? In a setting where voters' preferences are satiated, characterized by bliss points, this paper proposes a new balancedness condition which is satisfied when a Condorcet winner lies within the interior of the convex hull of voters' bliss points. We show that such a political compromise between the most preferred policies of different voter types can be decentralized as Lindahl equilibria.
