Exit and Inefficiency: The Effects of Ownership Type
利用1986-91年医院关闭数据，研究营利、非营利和政府医院中，低效率对退出概率的影响，发现营利和非营利医院中低效率者更易退出，政府医院则不然。
This study uses data on hospital closures to examine the relation between exit and inefficiency in an industry where for-profit, not-for-profit, and government firms coexist. The likelihood of hospital exit over the period 1986-91 is estimated as a function of hospital relative inefficiency, ownership type, and other factors, where hospital relative inefficiency is measured using residuals from estimation of a stochastic frontier cost function. We find that less efficient hospitals were more likely to exit when ownership was for-profit or not-for-profit, but that relative inefficiency did not have a significant effect on the probability of exit for government hospitals.
