Abstract

We provide representations giving the Condorcet Efficiency of Weighted Scoring Rules in three-alternative elections by considering the Modified Impartial Anonymous Culture condition (MIAC). This assumption only considers voting situations for which all Weighted Scoring Rules do not elect the same winner. It is concluded that the selection of a voting rule has a clear impact on the resulting Condorcet Efficiency. This makes a significant difference in what can be concluded from earlier studies.
