Abstract

We extend the Thomas (1985) dynamic optimizing model of money demand and currency substitution to the case in which the individual has restricted or no access to foreign currency denominated bonds. In this case currency substitution decisions and asset substitution decisions are not separable. The results obtained suggest that the significance of an expected exchange rate depreciation term in the demand for domestic money provides a valid test for the presence of currency substitution. Applying this approach to six Latin‐American countries, we find evidence of currency substitution in Colombia, Dominican Republic, and Venezuela, but not in Brazil and Chile. Les auteurs prolongent le modèle d'optimisation dynamique de demande de monnaie et de substitution de devises de Thomas (1985) au cas où l'individu a un accès restreint ou nul aux débentures en devises étrangères. Dans ce cas, les décisions de substitution de devises et de substitution d'actifs ne sont pas séparables. Les résultats obtenus suggèrent que la nature significative d'une variable enregistrant une dépréciation anticipée du taux de change dans l'équation de la demande de monnaie nationale fournit un test valide de la présence de substitution de devises. En appliquant cette approche à six pays d'Amérique latine, on découvre qu'il y a évidence de substitution de devises en Colombie, en République dominicaine, et au Vénézuéla, mais pas au Brésil et au Chili.
