Women are dramatically underrepresented in legislative bodies (supply), and most scholars agree that the greatest limiting factor is the lack of female candidates. However, voters’ subconscious biases (demand) may also play a role, particularly among conservatives. In this seminar, Jessica Preece discusses her findings from a field experiment conducted in partnership with a state Republican Party. She finds that party leaders’ efforts to increase both supply and demand (especially both together) result in a greater number of women elected as delegates to the statewide nominating convention. Her field experiment shows that simple interventions from party leaders can influence the behavior of candidates and voters, which ultimately leads to a substantial increase in women’s electoral success.
