Modeling Representation of Minorities Under Multiwinner Voting Rules

TL;DR

This paper investigates how different multiwinner voting rules impact minority representation and explores whether these rules can achieve proportional representation, through experimental and quantitative analysis.

Contribution

It provides a comparative analysis of multiwinner voting rules, highlighting their effects on minority representation and their potential to ensure proportionality.

Findings

Voting rules significantly influence minority representation

Some rules can achieve proportional representation

Experimental results demonstrate varying effectiveness of rules

Abstract

The goal of this paper is twofold. First and foremost, we aim to experimentally and quantitatively show that the choice of a multiwinner voting rule can play a crucial role on the way minorities are represented. We also test the possibility for some of these rules to achieve proportional representation.
