This paper investigates the relationship between interest rate and volatility of real effective exchange rate in Brazil. Through a simultaneous multivariate GARCH model, which allows estimating equations for the mean and variance in a single stage, it was observed that: it’s not possible to...

Interest rate, exchange rate and the system of inflation target in Brazil. In the consensus view of the Brazilian system of inflation targeting, the core of inflation is due to demand shocks; the rate of interest is set to control demand; and some variation in the exchange rate happens as...

This paper aims to estimate the equilibrium real exchange rate for the Brazilian economy. The equilibrium exchange rate is defined as the level of exchange that guarantees that the net foreign asset position is stable over time. An econometric model is estimated using cointegration techniques....
