Voting for gender balancing? The effect of a multiple-vote system on women’s representation

Abstract Does permitting voters to select multiple candidates in majoritarian elections increase diversity among those elected? While majoritarian systems typically use single-vote ballots, research suggests that allowing multiple selections may increase the representation of women and racial minorities. However, empirical evidence regarding actual voter behavior remains limited. To address this gap, we conducted a survey experiment that varied the number of selectable candidates from one to three in multimember local elections. The results revealed that, under the multiple-vote condition, respondents were more likely to alternate by gender, particularly in their second- and third-ranked choices, supporting the theory that multiple voting fosters more diverse representation. Nevertheless, men often emerged as the first-ranked choice, giving them an overall advantage at the aggregate level.
