This paper generalizes the popular stochastic volatility in mean model of Koopman and Hol Uspensky (2002) to allow for time-varying parameters in the conditional mean. The estimation of this extension is nontrival since the volatility appears in both the conditional mean and the conditional...

This paper analyzes the role of the United States in the global economy and examines the extent of global spillovers from changes in U.S. growth, monetary and fiscal policies, and uncertainty in its financial markets and economic policies. Developments in the U.S. economy, the world's largest,...

The literature on uncovered interest rate parity (UIP) shows two empirical puzzles. One is the failure of UIP, and the other is the unstable coefficients in the UIP regression. We propose a time-varying coefficients model with stochastic volatility and US structural shocks (TVC-SVX) to study how...

This paper estimates the Brazilian NAILO (Nonaccelerating Inflation Level of Output), obtains (Bayesian) probability bands for the Nailo and for its growth rate, and investigates the relationship between deviations of output with respect to the Nailo and the acceleration of inflation. As...

We estimate a VAR model of the Phillips curve with an exchange rate shock to the Brazilian economy. Several different specifications, with different time frequencies, were estimated. Overall the results were robust to these changes, and can be summed up in the following: i) the pass-through to...

The goal of this article is to estimate the New Keynesian Phillips Curve for Brazilian economy. Due to some specifications problems in regressions estimated by IV method, the GMM-HAC methodology was used in order to address them. We noted the robustness of the results performing a detailed...

We estimate the Phillips curve with an exchange rate shock to the Brazilian economy. Besides panel data, we estimate the Phillips curve by time series methodology, including Bayesian techniques and Smoothing Transition Regressions (STR) model. The econometric results show three important...

There is no consensus over the importance of “global forces” on inflation. This study explores the role of structural breaks in the inflation process, and their timing, whether it is common across countries, and the extent to which ‘global forces' are relevant. Three conclusions stand out....
