My research interests are in the fields of health economics, industrial organization, and econometrics, wherein I apply theoretical and empirical methods from the econometrics and industrial organization literatures to questions of hospital, physician, and insurer behaviors. The majority of my ongoing work examines the relationship between hospitals and physicians and how this relationship may influence hospital production, pricing, and physician behaviors. My research also examines several aspects related to the Medicare Advantage market. In addition to issues of competitiveness, pricing, and network formation, my research on Medicare Advantage often relates to literature on the economics of information, where my coauthors and I examine how consumers and firms respond to changes in available plan information (i.e., quality disclosure).
