I am an Assistant Professor of Management and Organization at USC Marshall School of Business.
My research interest broadly lies in firm strategy and business economics, with a focus on innovation and entrepreneurship. The key question in my research is how firms strategically manage their innovation processes and outcomes in response to ever-changing business environments. I explore three different types of competition – product market competition, competition for labor forces, and competition for IP rights – and how relevant policies reshape firm innovation strategies.
In my most recent study, for example, I study how firms change their intensity and breadth of innovation in response to market competitiveness. The formation and breakup of price fixing cartels provide an ideal novel setting to proxy for competition, or lack thereof. I assembled a unique dataset on all 461 prosecuted cartel cases from 1975–2016, where I match 1,818 collusive firms to patent data and the U.S. Census microdata. I then use a difference-in-difference methodology, comparing colluding firms to carefully defined counterfactual firms.
I earned my Ph.D. from UC Berkeley’s Haas School of Business (Business and Public Policy Group). I hold a B.A. in Economics and an M.A. in Business Administration from Seoul National University. I also served the Republic of Korea Army and honorably discharged as a sergeant.
