SUMMARY:Seminar: Strategy-Proof Rules on Partially Single-Peaked Domains
DESCRIPTION:Seminar at IGIDR by Dr. Gopakumar Achuthankutty\, Centre for Development Economics\, Delhi School of Economics\, New Delhi.\n\nDate & Hour: 24 June 2019\, 4:00 pm\n\nVenue: Seminar Hall 1\n\nTitle: Strategy-Proof Rules on Partially Single-Peaked Domains\n\nAbstract: We consider domains that exhibit single-peakedness only over a subset of alternatives. We call such domains partially single-peaked and provide a characterization of the unanimous and strategy-proof social choice functions on these domains. As an application of this result\, we obtain a characterization of the unanimous and strategy-proof social choice functions on multi-peaked domains (Stiglitz (1974)\, Epple and Romano (1996a))\, multiple single-peaked domains (Reffgen (2015)) and single-peaked domains on graphs (Demange (1982)\, Schummer and Vohra (2002)). As a by-product of our results\, it follows that strategy-proofness implies tops-onlyness on these domains. Further\, we show that strategy-proofness and group strategyproofness are equivalent on these domains.
