Gender bias and women’s political performance

Abstract

We model voters’ gender bias as a prejudice on women’s competence coming from a distorted prior. We analyse the effect of this bias in a two-period two-party election model in which voters care about both policy preference and competence. We find that, if voters (wrongly) believe that women are drawn from a distribution of competences with higher weights on lower values, female politicians are less likely to win office but, when elected, they are on average more competent than male elected officials. As a consequence, female incumbents seek re-election more often.
