Black women are underrepresented in the field of economics, and for those who enter the profession, being one of a few can be lonely. On this episode of On the Evidence, host J.B. Wogan talks with Anna Opoku-Agyeman and Fanta Traore about the Sadie Collective, a group they helped form, which seeks to increase the number of black women in economics and is named after the first African American to earn a PhD in economics.
