Research on the Hospital Market: Recent Advances and Continuing Data Needs

Abstract

Research focused on the hospital market has been instrumental in furthering our understanding of the role of competition in health care. Such research would not have been conducted without the extensive public use data that have been made available to researchers. In particular, path-breaking studies were made possible thanks to access to Medicare and state all-payer discharge data. This paper describes recent advances in our understanding of hospital competition and speculates about what we could learn if additional data were available.
