Résumé

Dans cette étude, il s’agit de caractériser le taux de change réel d’équilibre de long terme d’une petite économie ouverte à deux secteurs de production, dans laquelle les agents ont une durée de vie finie au sens de Blanchard (1985). Ce cadre théorique permet de relâcher l’hypothèse d’égalité entre le taux de préférence pour le présent et le taux d’intérêt mondial. Par ce biais, l’écart entre le taux d’intérêt et le taux de préférence pour le présent détermine la position financière nette de l’économie domestique vis-à-vis du reste du monde. Celle-ci conditionne en retour la réaction des principales variables économiques à une modification exogène du taux d’intérêt. L’impact d’une hausse du taux d’intérêt sur le taux de change réel d’équilibre dépend de la valeur des élasticités de la production par rapport au capital dans les deux secteurs, tandis que la consommation et le stock de capital se comportent différemment selon la position financière du pays.

Summary

Summary

This article focuses on the long-run real equilibrium exchange rate in a dependent economy with overlapping generations. We assume as in Blanchard (1985) that there is no intergenerational link. In this framework, the domestic rate of time preference need not be equal to the world interest rate. Thus, the spread between the rate of time preference and the interest rate determines the net financial position of the domestic country. We analyse the consequences of an increase in the world interest rate. The real exchange rate response depends on the capital intensity of the two sectors. Whereas, the consumption and capital reactions relies on the net financial position of the domestic country vis-à-vis the rest of the world.
