摘要：Abstract The goal of this paper is to evaluate the behavior of the main parameters of the Brazilian economy through the estimation of an open-economy dynamic stochastic general equilibrium (DSGE) model using Bayesian methods and allowing for Markov switching of certain parameters. Using the {DSGE} model developed by Justiniano and Preston (2010) and the solution method of the Markov switching {DSGE} (MS-DSGE) model proposed by Farmer et al. (2008), this paper found a superior fit in the data of Markov switching models, rejecting the hypothesis of constant parameters in {DSGE} models for the Brazilian economy.
