Inflation Dynamics and the Output‐Inflation Trade‐Off : International Panel Data Evidence

We explore the impact of inflation and its variability on the output‐inflation trade‐off using a single‐step approach in a panel data context. Previous empirical approaches focus on either cross‐country or country‐by‐country time‐series analyses. We employ a dynamic heterogeneous panel specification using an all‐encompassing estimation framework accounting for parameter heterogeneity, cross‐sectional dependence, dynamics, and nonstationarity. Our sample covers 60 countries from 1970 to 2010. While inflation variability reduces the trade‐off for specific periods and country groups, an unambiguous and more pronounced negative relation emerges between the inflation rate and the trade‐off. The findings are consistent with the New Keynesian view
