Abstract: This paper analyzes the performance of the central banks in inflation targeting (IT) countries by examining their success in achieving their explicit inflation targets. For this purpose, we decompose the inflation gap, the difference between actual inflation and the inflation target, into predictable and unpredictable components. We argue that the central banks are successful if the predictable component diminishes over time. The predictable component of the inflation gap is measured by the conditional mean of a parsimonious time-varying autoregressive model. Our results find considerable heterogeneity in the success of these IT countries in achieving their targets at the start of this policy regime. Our findings suggest that the central banks of the IT adopting countries started targeting inflation implicitly before becoming an explicit inflation targeter. The panel data analysis suggests that the relative success of these countries in reducing the gap is influenced by their institutional characteristics, particularly fiscal discipline and macroeconomic performance.
