Coalitional Manipulation of Voting Rules: Simulations on Empirical Data

Using computer simulations based on empirical data, we show that seven voting rules that we call the IRV family (Instant-Runoff Voting, exhaustive ballot, Condorcet-IRV, Benham, Smith-IRV, Tideman and Woodall) are less sensitive to coalitional manipulation than a large selection of prominent voting rules. While the relative performances of these seven rules still deserve further investigation, we show that the differences are at most marginal.
