Benjamin N. Roth

Ben Roth is an assistant professor of business administration in the Entrepreneurial Management Unit, teaching The Entrepreneurial Manager to MBA students. He is a development economist that employs both economic theory and field experimentation to pursue questions in two overlapping agendas: understanding and relaxing the constraints to small-scale entrepreneurship in the developing world, and understanding how investors should behave when they have both financial and social preferences. 

Ben earned a BA in economics from Washington University in St. Louis and a PhD in economics from MIT.
