This paper carries out an estimation of a time-varying NAIRU considering the labor supply components.Under this approach the average NAIRU was about 10.8% for the sample period 1984-2010.In addition, given the existence of an inflation target, we estimated a Phillips curve extended with an inflation expectations rule that considers these targets between 1991 and 2010.This estimation allowed us to compute the "compatible inflation target unemployment rate" (CITUR).Given the declining trend of the targets as well as some lack of credibility, its average level was about 11.8% for period 1999-2010.
