Effet d’un choc monétaire sur l’inflation: une approche par un modèle DSGE

This work investigates the impact of an increase in the money supply on inflation using DSGE model in Madagascar. The results showed a strong positive correlation between these two variables, confirming the economic theory that an increase in the money supply leads to a proportional increase in inflation. The study also revealed that the increase in the money supply has a significant effect on inflation in the short term, but this effect quickly diminishes and disappears after about twelve quarters.Targeted monetary policies may limit short-term effects on inflation, but strcutural and busgetary policies in the long term are needed to sustainably reduce inflation and promote sustained economic growth.
