The research group “Health Care Markets and Health Policy” is dedicated to the analysis of health care markets and the evaluation of health policy reforms. Goal of the group is to gain insights into how the health care system can be improved. The research focus is on the supply of medical services, in particular market structure, reimbursement schemes, and digital health. Methodologically, the analyses are based on publicly available as well as self-collected administrative, survey, and experimental data to identify causal effects using modern econometric methods.
