We find that the effects of ownership status are quantitatively important. Areas with a presence of for-profit hospitals have approximately 2.4 percent 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. ER -
