On strategy-proofness and symmetric single-peakedness
We characterize the class of strategy-proof social choice functions on the domain of symmetric single-peaked preferences. This class is strictly larger than the set of generalized median voter schemes (the class of strategy-proof and tops-only social choice functions on the domain of single-peaked preferences characterized by Moulin (1980)) since, under the domain of symmetric single-peaked pre...
متن کاملConsensus and Single - Peakedness
Consider a set of K alternatives. We say that an alternative is socially acceptable if the number of individuals that rank it among their most preferred half of the alternatives is at least as large as the number of individuals that rank it among the least preferred half. A Condorcet winner is not necessarily socially acceptable. We propose a concept of consensus as a condition on preference pr...
متن کاملOn Merging Strategy-Proofness
Merging operators aim at defining the beliefs/goals of a group of agents from the beliefs/goals of each member of the group. Whenever an agent of the group has preferences over the possible results of the merging process (i.e. the possible merged bases), she can try to rig the merging process by lying on her true beliefs/goals if this leads to a better merged base according to her point of view...
متن کاملPeakedness and peakedness ordering
The peakedness of a random variable (RV) X about a point a is defined by Pa(x) = P(|X − a| ≤ x), x ≥ 0. A RV X is said to be less peaked about a than a RV Y about b, denoted by X ≤pkd(a,b) Y , if P(|X − a| ≤ x) ≤ P(|Y − b| ≤ x) for all x ≥ 0, i.e., |X − a| is stochastically larger than |Y − b|. These generalize the original definitions of Birnbaum (1948) [2] who considered the cases where X and...
متن کاملStrategy - Proofness , Core , and Sequential Trade ¤
We extend the Shapley-Scarf (1974) model-where a …nite number of indivisible objects is to be allocated among a …nite number of individuals-to the case where the primary endowment set of an individual may contain none, one, or several objects and where property rights may be transferred (objects inherited) as the allocation process unfolds, under the retained assumption that an individual consu...
