This study examines the relative impacts of human capital and market conditions on the economic rents associated with hospital privileges in the market for footcare. An empirical model of hospital privileges for podiatrists is formulated based on the Pauly-Redisch model of hospital behavior. The privilege model is then incorporated into a model of podiatrists' earnings via a selection adjustment as proposed by Heckman and Lee. The results indicate the persistance of economic rents even after controlling for unobserved 'quality' factors.
本研究考察了人力资本和市场条件对足部护理市场中与医院特权相关的经济租金的相对影响。基于医院行为的保利-雷迪施模型，构建了足病医生医院特权的实证模型。然后，按照赫克曼和李所提议的选择调整方法，将特权模型纳入足病医生收入模型。结果表明，即便在控制了未观察到的“质量”因素之后，经济租金依然存在。
