To what extent are some voting rules more vulnerable to strategic manipulation than others? In order to answer this question, representations are developed for the coalitional manipulability of eight voting rules under various assumptions concerning the likelihood that given voters' preference...

Median Voting Rule (MVR) has been proposed as a voting rule, based on the argument that MVR will be less manipulable than Borda Rule. We find that plurality rule has only a slightly greater probability of manipulability than MVR, and that Copeland Rule has a smaller probability of manipulability...

A constant scoring rule asks each individual to vote for a given (and constant) number of alternatives and the alternative with the most votes is elected. A sequential constant scoring rule applies this principle in a process of sequential elimination. Constant scoring rules as well as...
