Time series analysis of inflation targeting in selected countries

We analyze a set of countries which adopted inflation targeting (IT) as a policy tool. We model the pre-IT period with ARMA and GARCH methods, and conduct the one-step ahead forecasting for the remainder of the times series data. The actual and forecasted inflation levels are compared for each country. We find that even though the actual inflation levels are lower than the forecasted ones, there is no statistical evidence to suggest that the adoption of IT causes a structural break in the inflation levels of the countries which adopt IT.
