Research Interests

Professor Kolstad’s research interests lie in the intersection of health economics, industrial organization and applied microeconomics. The unifying theme of his work is an effort to understand how information, market structure and regulation alter firm organization, individual incentives and, ultimately, performance and welfare. In recent work he has studied entry and competition in hospital markets, the impact of specialty hospital entry on general hospital service provision and the impact of quality information on demand as well as intrinsic surgeon incentives. In ongoing work Dr. Kolstad seeks to estimate the welfare gains from risk protection provided by health insurance. In related work he is studying the impact of the Massachusetts health insurance expansion on a variety of outcomes of interest to researchers and policy makers. In a separate project he is studying the role of social networks among physicians in referral patterns.
