Abstract

L'objectif principal du document est de contribuer aux débats actuels sur la spécification des effets prix et revenus dans les modèles d'équilibre général calculable (EGC). L'auteur détaille une procédure qui permet d'introduire dans ces modèles n'importe quelle configuration régulière d'effets prix et revenus. L'approche s'appuie sur le concept de séparabilité latente. Cette notion autorise un même produit à appartenir à plusieurs groupes et par conséquent les effets de substitution entre produits passent par plusieurs canaux. Une illustration empirique démontre la validité de cette procédure et rappelle l'importance de la spécification de ces effets prix et revenus dans les modèles EGC.
