Despite making up roughly half of the U.S. population, women only make up about one-quarter of representatives and senators. And this trend is not just national—it holds true globally as well. What explains why women are underrepresented in politics? If women are just as likely to win elections as men do, then why are they less likely to run for office? In a recent paper, "Modeling Theories of Women's Underrepresentation in Elections," University of Chicago Professors Scott Ashworth, Christopher Berry and Ethan Bueno de Mesquita explore the facts and theories around why women are elected less than men in U.S. politics. In this episode, we speak with Ashworth, a Professor in the Harris School of Public Policy.
