Duverger's Law and Polarization in a Ranked Choice Citizen-Candidate Model

Authors: Bryan Jay Frandsen

This paper expands on a citizen-candidate model of electoral competition under both plurality rule and ranked choice voting. The paper finds that ranked choice voting nominally avoids Duverger’s Law by accumulating many identical candidates but yields fewer viable equilibrium policy positions than plurality rule. Additionally, ranked choice voting favors moderate candidates and policies, increasing the probability of their implementation compared to plurality rule. This moderate bias leads to lower polarization in equilibrium than is possible under plurality rule.
