Michael Ewens is a scholar who analyzes the dynamics and functioning of the entrepreneurial finance sector, with a particular focus on venture capital and private equity. A major stream of Professor Ewens’ research investigates how private equity investors add value, revealing the sources of companies’ own financing frictions. A second theme of his research connects the public equity markets with the dynamics of private capital markets. Any spillovers between these capital markets impact the number of publicly traded companies, information about investment opportunities, and retail investors’ access to tradeable securities. Professor Ewens is a Research Associate at the National Bureau of Economic Research (NBER), Associate Editor of the Journal of Financial Economics, Associate Editor at the Review of Financial Studies, Associate Editor at the Journal of Corporate Finance, and Co-Editor of the Journal of Economics & Management Strategy.

Professor Ewens obtained his BA in Mathematics and Economics from Washington University in St. Louis in 2004 and his PhD in Economics from the University of California, San Diego in 2010. Professor Ewens started his academic career as an Assistant Professor of Finance and Entrepreneurship at Carnegie Mellon University in 2010, then joined California Institute of Technology as an Associate Professor in 2014, and was promoted to Professor in 2019.
