Abstract

The objective of this article is to perform an analysis of monetary policy in Brazil, using a Markov Chain Autoregressive Vector (MS-VAR) model, in the search for evidence of non-linearity in the relationship between exchange and prices in Brazil. The analysis showed that in periods of exchange appreciation, both on the demand side and the supply side, there is a set of forces that determine a downward trajectory for price levels, suggesting that the exchange rate plays a fundamental role in the control of inflation. However, there is a need to reassess the role of the exchange rate in Brazil.
