Abstract: We study the role of physicians in driving geographic variation of US healthcare utilization. We estimate a model that separates variation in average utilization of Medicare beneficiaries due to physicians, non-physician supply side factors, and patient demand. The model is identified by migration of patients and physicians across areas, as well as by variation in within-area matching. We find that physicians vary greatly in the intensity with which they treat otherwise similar patients, and that at least a third of geographic differences in healthcare utilization can be explained by differences in average physician treatment intensity. Conservatively, physicians are three times as important as non-physician supply-side factors in explaining geographic variation. Around three-fifths of physicians’ role comes from differences across areas in physician practice styles within the same specialty, while the other two-fifths reflects differences across areas in physician specialty mix.
