Abstract

Consumer demand models based on the concept of a representative or average consumer suffer from aggregation error. Misspecification of the underlying micro utility‐maximizing model, which is virtually inevitable, also results in error. This note provides a theoretical investigation of the relationship between the two types of error. Misspecified expenditure support functions for demand systems at the micro level induce the same misspecified structure in the corresponding expenditure functions at the macro level, and the errors at the two levels are shown to be of similar order. Les modèles de demande du consommateur fondés sur le consommateur moyen ou représentatif souffrent d'une erreur d'agrégation. Une mauvaise spécification du modèle sous‐jacent de micro maximisation de l'utilité, qui est à peu près inévitable, est aussi source d'erreur. Cette note propose un examen théorique de la relation entre ces deux types d'erreurs. La mauvaise spécification des fonctions de dépenses qui fondent les systèmes de demande au niveau micro induit la même mauvaise spécification dans les fonctions de dépenses au niveau macro, et les erreurs aux deux niveaux sont d'un ordre similaire.
