Abstract (Translated): 
This paper analyzes the dynamic properties of a DSGE model for Brazil, under alternative model parameterizations. First, we carefully review the literature in order to identify admissible ranges for the model's parameters. We then calculate selected impulse response functions (IRF) under various model parameterizations. We first analyze the sensitivity of IRFs to some of the model's parameters taken one at a time. We later analyze the model's IRFs global sensitivity: i) we randomly draw parameter values from the admissible ranges previously identified; ii) we calculate impulse response functions for selected variables and shocks under each draw; iii) by repeating this procedure many times, we obtain confidence intervals for the desired IRFs. According to our results, responses by some of the main macroeconomic variables to the selected shocks are compatible with stylized facts for the Brazilian economy and are reasonably robust to the choice of structural parameters with regard to their timing, but not their magnitude.
