There are many situations in which different groups make collective decisions by committee voting, where each group is … represented by a single person. Theoretical concepts suggest how the voting systems in such committees should be designed, but … these abstract rules can usually not be implemented perfectly. To find voting systems that approximate these rules the so …

There are many situations in which different groups make collective decisions by committee voting, with each group … represented by a single person. A natural question is what voting system such a committee should use. Concepts based on voting … the choice of voting systems based on such theoretical concepts, in this paper, I ask which systems individuals actually …

Numerous theoretical studies have shown that information aggregation through voting is fragile. We consider a model of … information aggregation with vote-contingent payoffs and generically characterize voting behavior in large committees. We use this …

Consider a voting procedure where countries, states, or districts comprising a union each elect representatives who … characterization of the efficient voting rule in terms of the weights assigned to different districts and the voting threshold (how … correlation structure of agents preferences, we analyze how voting weights relate to the population size of a country. We then …

This paper develops the symmetric power order, a measure of voting power for multicandidate elections. The measure … generalizes standard pivotality-based voting power measures for binary elections, such as Banzhaf power. At the same time, the … symmetric power order to show that pivotality only measures voting power in monotonic elections, and is not a good measure in …

political phenomena that ensued is presented. In the case of sophisticated voting over certain kinds of binary agendas, such as … sometimes yield “sophisticated sincerity”, where equilibrium voting behavior is indistinguishable from sincere voting. Under … behave leads to probabilistic voting models that typically yield utilitarian outcomes. Uncertainty among the voters over …

Utilitarian voting (UV) is defined in this paper as any voting rule that allows the voter to rank all of the … alternatives by means of the scores permitted under a given voting scale. Specific UV rules that have been proposed are approval … voting, allowing the scores 0, 1; range voting, allowing all numbers in an interval as scores; evaluative voting, allowing …

The paper elaborates the idea that voting is an instance of the aggregation of judgments, this being a more general … has been unproblematic whenever it has been based on an independent and unrestricted scale.
