WebThe main theorem of this paper is: The Gibbard-Satterthwaite theorem: A strategy-proof voting rule that is onto is dictatorial if the number of objects is at least three. 3 Some … WebThe proof crucially uses reverse hypercontractivity in addition to several ideas from the two previous proofs. Much of the work is devoted to understanding functions of a single voter, and in particular we also prove a quantitative Gibbard-Satterthwaite theorem for one voter. 1 …
