Discrete and Nondlscrete Quasiconvexlike Functions and Single-Peakedness (Unimodality)

Mathematische Operationsforschung Und Statistik Series Optimization, 1983
Donath and Elster's result on the equivalence of unimodal and x-convex (in the sense of Ponstein) functions in case of lower semicontinuity, together with some further results (relaxation of the semicontinuity condition etc.), is given for functions whose values are taken from a connected quasi order.

On Coalitional Stability and Single-peakedness [PDF]

, 2011
We study a one-dimensional voting game in which voters choose a policy from a one-dimensional policy set over which voters have single-peaked preferences. The purpose of this paper is to analyze coalitional behaviors under any given voting mechanism. We employ the notion of strong Nash equilibrium and identify a necessary and su¢ cient condition for a ...

Deliberation, Single-Peakedness, and Coherent Aggregation

American Political Science Review, 2021
Rational deliberation helps to avoid cyclic or intransitive group preferences by fostering meta-agreements, which in turn ensures single-peaked profiles. This is the received view, but this paper argues that it should be qualified.

STRATEGIC CANDIDACY AND SINGLE-PEAKEDNESS

The Japanese Economic Review, 2007
In elections, the voting outcomes are affected by strategic entries of candidates. We study a class of voting rules immune to strategic candidacy. Dutta et al. (2001) show that such rules satisfying unanimity are dictatorial if all orderings of candidates are admissible for voters’ preferences.

Single-peakedness and guttman scales: Concept and measurement

Public Choice, 1974
Interest in dimensionality arises in both formal theory and empirical work. An important example of the theoretical results has to do with locating the optimal spatial strategy for a political candidate or party. As Anthony Downs and others have pointed out, the party seeking to win an election should move to the center of the voter distribution if ...

On strategy-proofness and single peakedness

Public Choice, 1980
This paper investigates one of the possible weakening of the (too demanding) assumptions of the Gibbard-Satterthwaite theorem. Namely we deal with a class of voting schemes where at the same time the domain of possible preference preordering of any agent is limited to single-peaked preferences, and the message that this agent sends to the central ...

Research note Partial single-peakedness: An extension and clarification

Public Choice, 1986
Niemi (1969), in an important but neglected paper, found that when orderings were drawn from a simulation based on the impartial culture, the greater the proportion of voter orderings that were single-peaked (a condition he called partial single-peakedness), the more likely was there to be a transitive group ordering.

Black’s Single-Peakedness Condition

2008
Like Kekule’s vision about the ring structure of the carbon molecule, the notion of single-peaked preferences came to Duncan Black as a sudden flash of insight. In the 1940s, Black had independently rediscovered the concept of cyclical preferences and was looking for a way to avoid majority rule cycles (Black, 1958). In single-peakedness he found one.

A comment on “single-peakedness and guttman scales: Concept and measurement”

Public Choice, 1976
tn a recent article in this journal, Niemi and Weisberg (1974) have compellingly shown the falsity of the plausible assumption (made by Grofman, 1968 and others: see citations, Niemi and Weisberg, 1974) that Guttman scalability (see Stouffer, et al., 1950 MacRae, 1970) is equivalent to single peakedness (see Black, 1958 Arrow, 1962, and Coombs, 1964 ...
