Estimating Electricity Demand: The Cost of Linearising the Budget Constraint
对比了两种方法估计哥伦比亚麦德林居民阶梯电价下的电力需求弹性，并用广义选择性偏差校正法解决结果差异，对研究非线性定价的学者有参考价值。
This paper derives elasticity estimates for the electricity demand of a cross section of residential customers in Medellin, Colombia, where prices follow a rising block scheme. It contrasts methods following Jerry Hausman (1979, 1985) with those based on Harvey Rosen (1976). To resolve the difference between the results produced by the two methods, it uses a generalized selectivity bias corrections method due to Frank Vella (1990). Copyright 1992 by MIT Press.
