Abstract

In this paper we use a model of vertical product differentiation to cast doubt on the general validity of the import demand function as specified in macroeconomic models. The empirical importance of our theoretical concerns is then established. According to our first hypothesis, the share of a good’s imports in total imports is non‐increasing in domestic wages if the country has comparative advantage in high‐quality varieties of this good. The second hypothesis states that the share of a good’s imports is increasing in non‐wage domestic income if the country has comparative advantage in high‐quality varieties of this good. JEL Classification: F4, F41 Différenciation verticale des produits et fonction de demande d’importations : théorie et résultats. Dans ce mémoire, les auteurs utilisent un modèle de différenciation verticale des produits pour jeter certains doutes sur la validité générale de la fonction de demande d’importations telle que spécifiée dans les modèles macroéconomiques. L’importance empirique de ces malaises théoriques est étudiée à l’aide de deux hypothèses. La première hypothèse suggère que la part d’un bien dans les importations totales d’un pays ne va pas croître quand les salaires du pays s’accroissent si le pays a un avantage comparatif dans les variétés de haute qualité de ce bien. La seconde hypothèse suggère que la part d’un produit qui provient de l’importation croît quand le revenu intérieur non‐salarial s’accroît si le pays a un avantage comparatif dans les variétés de haute qualité de ce bien. On observe des résultats qui donnent un support empirique ferme à ces deux propositions en analysant les données en provenance de l’Allemagne, du Japon et des Etats‐Unis.
