Solidarity for public goods under single-peaked preferences: Characterizing target set correspondences

September 19, 2017

Abstract

We consider the problem of choosing a set of locations of a public good on the real line R. Similarly to Klaus and Storcken (2002), we ordinally extend the agents' preferences over compact subsets of R, and extend the results of Ching and Thomson (1996), Vohra 1999), and Klaus (2001) to choice correspondences. Specifically, we show that efficiency}and either population-monotonicity or one-sided replacement-dominance characterize the class of target set correspondences on the domains of single-peaked preferences and symmetric single-peaked preferences.

JEL Classification: C71, D63, D78, H41

Keywords: single-peaked preferences, population-monotonicity, replacement-dominance,  target set correspondences.
