Estudamos os impactos de uma mudança na taxa de juros e na taxa de câmbio sobre a inflação no Brasil. Com a desagregação do IPCA em 512 subitens, é possível mostrar que, após um aumento da taxa de juros ou uma depreciação cambial, a dispersão dos preços se altera. Os resultados indicam, ainda, que leva entre seis e doze meses até que a estrutura de preços volte a ser aquela que prevalecia antes da mudança. Este resultado é interessante por mostrar que não só o nível de preços agregado é afetado, mas a distribuição também, e leva até um ano para que esta se restabeleça.
We study how inflation in Brazil reacts to changes in the interest rates and in the exchange rate. Using a disaggregation of IPCA within 512 items, it is possible to show that, after an interest rate increase or exchange rate depreciation, price dispersion alters. Our results indicate, furthermore, that it takes from six to twelve months until price structure returns to the one that existed before the change. This result seems interesting because it shows that all price distribution is affected by a macroeconomic shock
