- W34853624 abstract "The geographic extent of markets for physicians is an important but little-explored issue for antitrust. Using patient flow data from a 2009 20% sample of Medicare beneficiaries, we define physician specialty-specific geographic markets for selected communities and calculate concentration within these markets. We find considerable variation in geographic market size by physician specialty and evidence of substantial concentration within physician markets, especially for specialists in smaller geographic areas. Additionally, given that our market definition methodology has been shown to define overly expansive markets, our concentration measures likely reflect a lower bound." @default.
