THE IMPACT OF MONETARY POLICY ON THE EXCHANGE RATE IN BRAZIL: IDENTIFICATION THROUGH HETEROCEDASTICITY

<p></p><p>ABSTRACT This study aims to analyze the effects of Brazilian monetary policy on the exchange rate in from 2004 to 2016 taking into account the endogeneity problem of monetary policy. To address the issue of endogeneity of monetary policy the method of identification through heteroscedasticity is used. The main advantage of this method is that it is based on the statistical behavior of the series, it is not necessary to make arbitrary assumptions of identification. The results show that there is a positive relationship between the interest rate and the exchange rate in Brazil.</p><p></p>
