In order to do so, we rely on unit root tests applied to nonlinear models, i.e. Kapetanios et al. (2003). The results point to the non-persistence of inflation hypothesis for most of the countries. In addition, the estimated models are stable in the sense that the variable tends to remain in the regime (low inflation or high inflation) once reached and changes between regimes are only achieved after a shock.
