Abstract
This paper analyzes the dynamics of Brazilian inflation between 1995 and 2016. By estimating Markovian models, we derive measures of uncertainties related to changes in monetary policy (regime uncertainty) and to random shocks (certainty equivalent). Our results show that the level and variability of inflation have reduced after the adoption of inflation targeting. In the same period, there were declines in regime uncertainties, with the exception of 2015 onwards, when inflation exceeded its upper limit and instabilities rose abruptly. It is also found that impulses in regime uncertainty impacts negatively production, consumption, and investment in the country.
