Abstract

This work proposes the application of a stochastic volatility model with jumps to the BRL/USD exchange rate. This model decomposes the process into transitory and permanent components that capture the jumps in the level of the unobserved volatility process. The model estimation is done using Bayesian inference, and jumps at the level of the volatility of the exchange rate are analyzed according to the main economic events in this sample. We conclude that the model is consistent with the changes in the Brazilian economy and the crises observed in the analyzed period.
