个体异质性是需求变化的重要来源。正确的福利比较需要考虑到普遍的异质性。我们考虑一般的异质需求,其中偏好和线性预算集在统计上是独立的。我们发现异质性维度和个体需求函数并未确定。我们还发现,价格变化的确切消费者剩余(个人平均)尚未确定,这激发了边界分析。我们使用收入效应的界限来推导平均盈余的相对简单的界限,包括离散/连续的选择。我们还概述了一种不使用收入效应界限的盈余界限方法。我们将收入效应界限的结果应用于汽油需求。我们发现此应用中的收入效应界限不太敏感。
Individual heterogeneity is an important source of variation in demand. Allowing for general heterogeneity is needed for correct welfare comparisons. We consider general heterogenous demand where preferences and linear budget sets are statistically independent. We find that the dimension of heterogeneity and the individual demand functions are not identified. We also find that the exact consumer surplus of a price change, averaged across individuals, is not identified, motivating bounds analysis. We use bounds on income effects to derive relatively simple bounds on the average surplus, including for discrete/continous choice. We also sketch an approach to bounding surplus that does not use income effect bounds. We apply the results with income effect bounds to gasoline demand. We find little sensitivity to the income effect bounds in this application.
