Revista CEPAL, 2018

Abstract: This article analyses Brazil’s recent inflation dynamic, considering different expectations environments within the New-Keynesian Phillips curve framework, to observe how the potential for discretionary behaviour by the monetary authority can interfere in economic agents’ forward-looking expectations, and how that interference can affect the way inflation responds to its inertial component and to business-cycle fluctuations. To that end, the study estimates the New-Keynesian Phillips curve and its hybrid version, using the heteroscedasticity-and-autocorrelation-consistent (HAC) estimator of the generalized method of moments (GMM). The results suggest that, when economic agents possess lower degrees of foresight, inflation will be more sensitive to business-cycle fluctuations the larger is its inertial component.
