Top monotonicity: A common root for single peakedness, single crossing and the median voter result
When members of a voting body exhibit single peaked preferences, pair-wise majority voting equilibria (Condorcet winners) always exist. Moreover, they coincide with the median(s) of the votersmost preferred alternatives. This important result, known as the median voter result, has been crucial in the development of public economics and political economy. Yet, there are many examples in the lit...
متن کاملTop monotonicity: a weak domain restriction encompassing single peakedness, single crossing and order restriction
When the members of a voting body exhibit single peaked preferences, majority winners exist. Moreover, the median(s) of the preferred alternatives of voters is (are) indeed the majority (Condorcet) winner(s). This important result of Duncan Black (1958) has been crucial in the development of public economics and political economy, even if it only provides a su¢ cient condition. Yet, there are m...
متن کاملManipulation and Single-Peakedness: A General Result
This article considers environments in which individual preferences are single-peaked with respect to an unspecified, but unidimensional, ordering of the alternative space. We show that in these environments, any institution that is coalitionally strategy-proof must be dictatorial. Thus, any nondictatorial institutional environment that does not explicitly utilize an a priori ordering over alte...
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 کاملSingle-Crossing, Strategic Voting and the Median Choice Rule
This paper studies the strategic foundations of the Representative Voter Theorem (Rothstein, 1991), also called the “second version” of the Median Voter Theorem. As a by-product, it also considers the existence of non-trivial strategy-proof social choice functions over the domain of single-crossing preference profiles. The main result presented here is that single-crossing preferences constitut...
