The Role of Physicians in Hospital Production
使用超越对数生产函数，分析医生对医院产出的影响，并比较教学与非教学医院的差异，发现医生能提升其他投入的生产率，且与其他资源存在替代关系。
We use a translog production function approach to examine the effects of medical staff physicians on hospital production, and how their effects differ in teaching and nonteaching hospitals. In teaching hospitals, we also focus on the special role of medical residents. We find that physicians have a strong positive influence on the productivity of other inputs, and that they are substitutes for other resources. Controlling for patient casemix causes significant changes in estimated marginal products; those of labor inputs increase and that of capital declines. The implications of our findings for policy are explored.
