The adjustment of nominal interest rates in Mexico: a study of the Fisher effect
Evidence is presented in favour of a Fisher effect between treasury bill interest rates and inflation in Mexico between 1978-94. The two series appear to be cointegrated and a unit proportional relationship between them would appear to exist such that treasury bills rates respond fully to inflationary shocks over a period of about 12 months. As such, monetary policy in Mexico is unlikely to have much impact on real rates of interest over the long-run.
