On obvious strategy-proofness and single-peakedness Arribillaga, R. Pablo Massó, Jordi Neme, Alejandro Obvious strategy-proofness Generalized median voters Single-peakedness Altres ajuts: UNSL (032016) ; Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) (PIP 112-201501-005055) ; Agencia Nacional de Promoción Científica y Tecnológica (PICT 2017-2355) We characterize the set of all obviously strategy-proof and onto social choice functions on the domain of single-peaked preferences. Since obvious strategy-proofness implies strategy-proofness, and the set of strategy-proof and onto social choice functions on this domain coincides with the class of generalized median voter schemes, we focus on this class. We identify a condition on generalized median voter schemes for which the following characterization holds. A generalized median voter scheme is obviously strategy-proof if and only if it satisfies the increasing intersection property. Our proof is constructive; for each generalized median voter scheme that satisfies the increasing intersection property we define an extensive game form that implements it in obviously dominant strategies. 2020 Article https://ddd.uab.cat/record/288851 urn:10.1016/j.jet.2020.104992 urn:oai:ddd.uab.cat:288851 urn:pure_id:273818457 urn:scopus_id:85078002991 urn:articleid:10957235v186p104992 urn:oai:egreta.uab.cat:publications/f6ea31e3-3393-4226-ad94-267a4870efaa eng Ministerio de Economía y Competitividad ECO2017-83534-P Ministerio de Economía y Competitividad SEV-2015-0563 Agència de Gestió d'Ajuts Universitaris i de Recerca 2017/SGR-711 Journal of economic theory ; Vol. 186 (2020), p. 104992 open access Aquest document està subjecte a una llicència d'ús Creative Commons.
