Abstract
The aim of the present study is to estimate the level of the natural rate of interest in Brazil. First, statistical filters are used for the ex ante and ex post real interest series. Then, an estimation of a dynamic Taylor rule is performed. These two estimates are eventually compared with the natural rate of interest obtained from a simplified macroeconomic state-space model following Laubach andWilliams (2003). The results indicate that monetary policy decisions caused the level of the real i ...
The aim of the present study is to estimate the level of the natural rate of interest in Brazil. First, statistical filters are used for the ex ante and ex post real interest series. Then, an estimation of a dynamic Taylor rule is performed. These two estimates are eventually compared with the natural rate of interest obtained from a simplified macroeconomic state-space model following Laubach andWilliams (2003). The results indicate that monetary policy decisions caused the level of the real interest rate to fluctuate around the natural rate of interest, showing that the Brazilian monetary authority can not be characterized as conservative over the analyzed period. O objetivo desse estudo é estimar o nível da taxa natural de juros para o Brasil. Inicialmente filtros estatísticos são usados nas séries de taxas de juros reais ex-post e ex-ante. Depois disso, estima-se uma regra de Taylor dinâmica. Os resultados desses dois experimentos são comparados com a taxa natural de juros que é estimada a partir de um modelo macroeconômico simplificado em formato de espaço de estados, tal como em Laubach and Williams (2003). Os resultados mostram que as decisões de política monetária geraram uma taxa de juros real que flutuou ao redor da taxa de juros natural estimada. Portanto, no período analisado, as autoridades monetárias brasileiras não podem ser caracterizadas, em média, como conservadoras. ...
