This paper attempts to extend empirical investigations about the asymmetric effects of monetary shocks in the Brazilian economy. We specify and estimate a nonlinear smooth transition vector autoregressive model including output, price level, exchange rate and a monetary policy indicator (Selic...

This paper investigates the effect of monetary and exchange rate shocks on disaggregated prices of the Brazilian Consumer Price Index (IPCA), from 1999 to 2011. We analyze the results of a factor-augmented vector autoregressive model (Favar), which are presented by different levels of...

This paper aims to discuss the determinants of Brazilian inflation measured by the Extended National Consumer Price Index (IPCA) from 2000 to 2009. We built 22 disaggregated series, the segments classification, crossing the classification in tradeables/non-tradeables/monitored prices with the...

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...

In this work we consider modeling the past volatilities through a Generalized Autoregressive Conditional Heteroskedasticity (GARCH) model using the Bayesian approach. Asymmetries in the shocks are accommodated by smooth transition models for the variance. We discuss problems related to the...

In this work, we consider modeling the past volatilities through an asymmetric generalised autoregressive conditional heteroskedasticity (Garch) model with heavy tailed sampling distributions. In particular, we consider the Student-t model with unknown degrees of freedom and indicate how it may...
