On strategy-proofness and the salience of single-peakedness Chatterji, Shurojit Massó, Jordi Strategy-proofness Single-peakedness Anonymity Unanimity Tops-onlyness Semilattice Altres ajuts: Singapore Management University, mitjançant subvenció C244/MSS13E001 We consider strategy-proof social choice functions operating on a rich domain of preference pro les. We show that if the social choice function satis es in addition tops-onlyness, anonymity and unanimity then the preferences in the domain have to satisfy a variant of single-peakedness (referred to as semilattice single-peakedness). We do so by deriving from the social choice function an endogenous partial order (a semilattice) from which the notion of a semilattice single-peaked preference can be de ned. We also provide a converse of this main nding. Finally, we show how well-known restricted domains under which nontrivial strategy-proof social choice functions are admissible are semilattice single-peaked domains. 2015 Working paper https://ddd.uab.cat/record/296701 urn:oai:ddd.uab.cat:296701 urn:oai:egreta.uab.cat:publications/3ff3e1df-2a3f-46ac-bb3b-c256944943b2 urn:pure_id:430622689 eng Ministerio de Ciencia e Innovación SEV-2011-0075 Ministerio de Economía y Competitividad ECO2008-0475 Agència de Gestió d'Ajuts Universitaris i de Recerca 2014/SGR-515 GSE Barcelona Graduate School of Economics Working Papers ; 2015 open access Aquest material està protegit per drets d'autor i/o drets afins.
