Coalitional manipulation of voting rules: simulations on empirical data

Using computer simulations based on empirical data, we show that seven voting rules 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 rules. While relative performances these still deserve further investigation, differences at most marginal.
