In 1921, Sadie Alexander became the first Black person in America to receive a PhD in economics. Then, she was functionally shut out of economics jobs, got a law degree, and became an attorney instead. A century later, economics has made notably little progress bringing Black women into the field. We work with The Sadie Collective to bring you three stories from three eras of recent history that show us how the field has changed, where it still falls short, and the unique joys of being a Black woman and loving economics. | Subscribe to our weekly newsletter here.
