On the Condorcet efficiency of evaluative voting (and other voting rules) with trichotomous preferences
Résumé
We investigate the propensity of evaluative voting (2, 1, 0) to fulfill Condorcet majority conditions in a framework where preferences are supposed to be trichotomous and only three candidates are in contention. In this framework, we also compare evaluative voting to other voting rules, including Borda rule, plurality rule and approval voting.
