چکیده

The Condorcet winner in an election is the candidate that would be able to defeat each of the other candidates in a series of pairwise elections. The Condorcet efficiency of a voting rule is the conditional probability that it would elect the Condorcet winner, given that a Condorcet winner exists. A closed form representation is obtained for the Condorcet efficiency of Borda Rule in three candidate elections under the impartial anonymous culture condition.  2001 Elsevier Science B.V.

Condorcet efficiency: A preference for indifference

The Condorcet winner in an election is the candidate who would be able to defeat all other candidates in a series of pairwise elections. The Condorcet efficiency of a voting procedure is the conditional probability that it will elect the Condorcet winner, given that a Condorcet winner exists. The study considers the Condorcet efficiency of weighted scoring rules (WSR’s) on three candidates for ...

Maximum likelihood approach to vote aggregation with variable probabilities

Condorcet (1785) initiated the statistical approach to vote aggregation. Two centuries later, Young (1988) showed that a correct application of the maximum likelihood principle leads to the selection of rankings called Kemeny orders, which have the minimal total number of disagreements with those of the voters. The Condorcet-Kemeny-Young approach is based on the assumption that the voters have ...

The Random Pairs Voting Rule: Introduction and Evaluation With a Large Dataset

This paper introduces and evaluates the Random Pairs voting rule to show that it significantly improves upon the communication complexity of balloting methods requiring complete orderings of candidates while maintaining a high Condorcet efficiency. To this end, Random Pairs is compared to plurality, 2-approval, Borda, and range voting on elections constructed from Yahoo! users’ ratings of music...

Uniform generation of anonymous and neutral preference profiles for social choice rules

The Impartial Anonymous and Neutral Culture (IANC) model of social choice assumes that the names of the voters as well as the identity of the alternatives are immaterial. This models allows for comparison of structural properties social choice rules (SCRs) for large values of the parameters empirically: whether Condorcet winners exist, whether Borda and Condorcet winners are identical, whether ...

Voting Systems and Strategic Manipulation: an Experimental Study

This paper presents experiments analyzing the strategic behavior of voters under three voting systems: plurality rule, approval voting, and the Borda count. Strategic behavior is significantly different under each treatment (voting system). Plurality rule leads voters to play in a more sophisticated manner, but not necessarily insincerely, displaying the lowest levels of manipulation. The oppos...
