Efficient Estimation of the Costs of Rent Controls: A Comment
扩展并澄清了Caudill等人（1989）关于租金管制市场中特征价格方程估计的论断，说明了租金管制法律性质如何影响两种估计方法的一致性。
Steven B. Caudill, Richard W. Ault, and Richard P. Saba (1989) introduce an approach to estimating a hedonic price equation that accounts for censoring d ue to rent control in a rental housing market. This paper extends and clarifies their assertion on the consistency of the ordinary least squares estimates and their estimates. The authors indicate how the nature of the rent control law affects the consistency propertie s of the two estimation methods. Copyright 1993 by MIT Press.
