This paper studies the dynamics of Mexican inflation by using a wavelet multiresolution analysis on 16 indexes of the … Mexican Consumer Price Index. This enables us to estimate the long-term trend, seasonality, and local shocks of the inflation … detected in the inflation series.

Long memory implies that shocks have a long … such level shifts are not unlikely for inflation, where the shifts may be caused by sudden oil price shocks, we examine … exaggerated. Our main findings are that apparent longmemory is quite resistant to level shifts, although for a few inflation rates …
