core inflation, trimmed means

Resumen

The concept of core inflation has been central to the discussions concerning macroeconomic policy management. In spite of this fact, no single measure of this concept has achieved consensus so far. Here, we propose the application of a statistical methodology based on trimmed means, where the amount of trim is based on a benchmark provided by a common stochastic components model, which we believe captures the essence of the core inflation concept. We apply this measure to the IPC-FIPE and IPCA-IBGE, two of the leading consumer price indexes in Brazil, and comment on the results.
