Resumo
This work aims to analyze the relationship between monetary policy and inflation persistence in recent years, after the introduction of the inflation targeting regime in Brazil. Through a simplified new-Keynesian model, the degree of inflation-gap persistence is modeled as a function of the monetary policy rule weights. The time-varying Taylor rule is confronted with the estimated curve of inflation-gap persistence, demonstrating that changes in monetary policy lead to changes in the level of inflation persistence in the economy. An adaptation of the model with a Taylor rule that incorporates the output gap expectations, reaches the same results more accurately.
