The IMF Working Papers series is designed to make IMF staff research available to a wide audience. Almost 300 Working Papers are released each year, covering a wide range of theoretical and analytical topics, including balance of payments, monetary and fiscal issues, global liquidity, and national and international economic developments.
This paper examines the factors underlying the stability of inflation observed following devaluations of the Spanish peseta, which took place during the 1992-93 Exchange Rate Mechanism (ERM) crisis. The long-run equilibrium relationships between the exchange rate and the aggregate price indices are estimated using the Johansen maximum likelihood-method. The short-run dynamics are obtained from error-correction models. The model is then simulated by calibrating changes in the exogenous variables to their actual values. The results indicate that the cost-push-up effect of devaluations may have been completely offset by determinants of the cyclical position of the economy and the low inflation rate in 1993-94 should not be viewed as unusual.
