Hospital Ownership and Technical Inefficiency
分析美国医院四种所有权结构（私人非营利、私人营利、联邦、州及地方政府）的技术效率差异，使用距离函数衡量多产出医院的技术效率，为理解所有权对效率的影响提供实证依据。
The theoretical industrial organization literature cites varying factors which might influence the degree of technical efficiency achieved under different ownership structures in the US hospital industry. Unfortunately, this literature offers no consensus regarding the net direction and magnitude of these various effects. This study analyzes the four types of ownership structure in the US hospital industry—private nonprofit, private for-profit, federal, and state and local government. Distance functions are used to measure technical efficiency of hospitals producing multiple outputs relative to other hospitals in the sample, allowing comparisons among the different ownership types.
