The Effects of Hospital Ownership on Medical Productivity
分析1985-1996年美国非农村老年心脏病患者数据，发现营利性医院的存在使医疗支出降低约2.4%而患者健康结果不变，表明营利性医院对医疗生产率有正向溢出效应。
To develop new evidence on how hospital ownership and other aspects of hospital market composition affect health care productivity, we analyze longitudinal data on the medical expenditures and health outcomes of the vast majority of nonrural elderly Medicare beneficiaries hospitalized for new heart attacks over the period 1985-1996. We find that the effects of ownership status are quantitatively important. Areas with a presence of for-profit hospitals have approximately 2.4% lower levels of hospital expenditures, but virtually the same patient health outcomes. We conclude that for-profit hospitals have important spillover benefits for medical productivity.
