Abstract

We examine the current account effect of a terms‐of‐trade deterioration for a small country model, incorporating weakly non‐separable preferences à la Shi (1994) under endogenous time preference. This enables us to emphasize a welfare change as an important determinant of the current account. Even with increasing marginal impatience, the Harberger‐Laursen‐Metzler effect occurs if consumers' preference toward imports is sufficiently wealth enhanced: in that case a terms‐of‐trade deterioration must reduce steady‐state welfare to shift preference away from imports to exports. Several empirical implications are also derived. JEL Classification: F41; F32 Préférences faiblement nonséparables et l'effet de Harberger‐Laursen‐Metzler. L'auteur examine l'effet sur le compte courant d'une détérioration des termes d'échange dans un modèle d'un petit pays, quand les préférences sont faiblement nonséparables à la Shi (1994) et que la préférence temporelle est endogène. Cela permet de souligner qu'un changement dans le niveau de bien‐être est un déterminant important du compte courant. Contrairement à ce qu'on trouve dans la littérature spécialisée, même quand on postule une impatience marginale croissante, l'effet Harberger‐Laursen‐Metzler se produit si la préférence des consommateurs pour les importations est suffisamment dépendante du niveau de richesse: dans ce cas‐là, une détérioration des termes d'échange doit réduire le niveau de bien‐être en régime permanent de manière à déplacer les préférences des importations vers les exportations. On déduit certaines implications empiriques de ces résultats.
