 abstract = {The purpose of this paper is to present estimates of production functions for hospitals in which a measure of the level of physician input is utilized. Since no data on the total number of hours worked by non-salaried physicians is available for a large sample of U.S. hospitals, alternative measures of physician input had to be constructed. As these measures are somewhat imperfect, the results I obtain should be considered tentative and preliminary.},
