Abstract

The neutral rate of interest is an important concept and communication tool for central banks. We develop a structural macroeconomic model to study the determinants of the neutral real rate of interest in a small open economy. The model captures domestic factors such as population aging, declining productivity, rising government debt, and inequality. Foreign factors are captured by changes in the global neutral real rate. We use the model to evaluate secular dynamics of the neutral rate in Canada from 1980–2018 and find that changes in both foreign and domestic factors resulted in a protracted neutral rate decline. Le taux d'intérêt neutre est un concept important et un outil de communication pour les banques centrales. Nous développons un modèle macroéconomique structurel pour étudier les déterminants du taux d'intérêt réel neutre dans une petite économie ouverte. Le modèle tient compte de facteurs nationaux tels que le vieillissement de la population, la baisse de la productivité, l'augmentation de la dette publique et les inégalités. Les facteurs étrangers sont pris en compte par les variations du taux réel neutre mondial. Nous utilisons le modèle pour évaluer la dynamique séculaire du taux neutre au Canada de 1980 à 2018 et constatons que les changements dans les facteurs étrangers et nationaux ont entrainé une baisse prolongée du taux neutre.
