Much of my current research examines the impacts of changing financial incentives, regulations, and organizational structures on health care provision and costs. One aspect of work in this area involves studying impacts of managed care and related insurance arrangements on things like health care costs, the pricing of physician services, prices for health insurance, and the availability and utilization of medical technologies. Other work examines factors influencing the adoption and use of medical technologies more generally, including particular work on imaging equipment. I am also interested in a range of other questions about health care systems, physicians organizations, provider compensation, health care cost growth, and health care quality.
