Demand Estimation with Expenditure Measurement Errors on the Left and Right Hand Side
指出在消费者预算分配模型中，因变量（个别商品消费）的测量误差会传导至自变量（总消费支出），导致两阶段最小二乘法失效，并提出了修正方法，应用于英国燃料需求数据。
Let x be total consumption expenditures. Measurement errors in consumer budget allocation models cause unusual problems because errors in the dependent variables, consumption on individual goods, contribute to errors in the regressor x. Empirically adequate budget share models, like the AIDS, translog, and quadratic AIDS, are linear or quadratic in log x. It is shown that, for these specifications, two stage least squares fails to correct for the measurement error. A simple technique for recovering consistent estimates from two stage least squares is provided, along with an efficient generalized method of moments estimator. The method is applied to U.K. fuel demand data. Copyright 1996 by MIT Press.
