Martin Salm (Tilburg University) and Ansgar Wuebker ( RWI Essen) won the "Wissenschaftspreis der deutschen Gesellschaft fuer Gesundheitsoekonomie" (research prize of the German Health Economics Association) for 2019 for the paper "Sources of Regional Variation in Healthcare Utilization in Germany" published in the Journal of Health Economics.


The researchers examine sources of regional variation in ambulatory care utilization in Germany. They exploit patient migration to examine which share of regional variation in ambulatory care utilization can be attributed to demand factors and to supply factors, respectively. Based on administrative claim-level data they find that regional variation can be overwhelmingly explained by patient characteristics. Their results contrast with previous results for other countries, and they suggest that institutional rules in Germany successfully constrain supply-side variation in ambulatory care use between German regions for most patients. Furthermore, they find that both demographics and other patient characteristics substantially contribute to regional variation and that causes of regional variation vary when comparing different regions within Germany.

Dr. Martin Salm is an associate professor at the Department of Econometrics and Operations Research at Tilburg University. His research fields are in health economics and applied microeconomics.
