Abstract

A famous stylized fact in comparative politics, Duverger' s Law, is that electoral systems based on single ballot winner-take-all plurality voting will produce bipartisan competition. This paper presents an equilibrium model of elections in which this stylized fact emerges a logical implication of rational strategic voting behavior by individuals in a large heterogeneous electorate.
