Abstract

We study the relationship between average inflation and inflation uncertainty in Mexico from 1960-1997. Friedman (1977) and Ball(1992) propose models where higher inflation creates increased uncertainty, whereas Cukierman & Meltzer (1986) and Cukierman (1992) argue that an apportunistic Central Bank will take advantage of higeruncertainty to raise the average inflation rate. We test these theories simultaneously using a GARCH-M model for monthly Mexican inflation. We find that higher inflation causes increased uncertainty as predicted by Friedman and Ball. However, contrary to the models of Cukierman and Meltzer, increased inflation uncertainty is associated with lower rather that higher average inflation. This result, that the Central Bank of Mexico stabilizes inflation to help reduce uncertainty, corresponds whit Grier & Perry's (1998) findings for the Central Banks of the USA and Germany.// En este trabajo estudiamos la relación entre la tasa de inflación promedio y la incertidumbre inflacionaria en México de 1960 a 1977.Friedman (1977) y Ball (1992) proponen modelos en los que la infación alta causa un aumento en la incertidumbre inflacionaria, mientras Cukerman y Meltzer (1986) y Cukierman (1992) discuten que un banco central puede aprovecharse de la incertidumbre y causar un aumento en la inflación promedio. Probamos estas teorías usando un modelo GARCH-M para la tasa de inflación mensual en México. Encontramos que aumentos en la tasa de inflación resulta en una mayor incertidumbre, como pronosticaron Friedman y Ball. Sin embargo, en contra de los modelos de Cukierman y Meltzer, mayor incertidumbre inflacionaria es asociada con menos en vez de más inflación promedio. Este resultado, con el que el Banco de México estabiliza la inflación para reducir la incertidumbre, es congruente con los obtenidos por Grier y Perry (1998) para los bancos centrales de los Estados Unidos y Alemania.
