Estimation of Demand Functions Using Cross‐Sectional Household Data: The Problem Revisited
提出一种修正选择性偏差的方法，利用横截面数据估计需求函数，假设价格在不同家庭间变化，并应用于牛肉支出数据。
Abstract A procedure that corrects for selectivity bias is proposed to estimate demand functions using cross‐sectional data under the assumption that prices vary across households. This procedure, which extends the work by Cox and Wohlgenant, includes a two‐equation system of expenditure and unit value functions. This model is applied to household expenditures for beef steaks and roasts.
