Abstract

Récemment, Lawrence (1989) et Kohli (1994) ont estimé des indices de prix agrégés pour les importations et exportations canadiennes en utilisant un modèle conceptuel à deux niveaux. Les auteurs mettent en évidence le fait que ces deux études n'ont pas réussi à prendre en compte l'ensemble complet des contraintes imposées aux paramètres des fonctions (d'agrégation) des prix. On montre en effet que la normalisation conventionnelle des données effectuée dans les recherches empiriques implique l'imposition d'une restriction supplémentaire sur certains des paramètres. Comme la dérivation des fonctions de prix est un cas particulier de l'estimation de systèmes de fonctions de demande d'intrants sous des conditions de rendements d'échelle constants, cette note a un intérêt qui va bien au delà des deux études précitées. A titre d'illustration, trois formes fonctionnelles flexibles communément employées sont estimées et l'impact de cette contrainte supplémentaire sur les valeurs des élasticités prix obtenues est examiné.
