Dynamics and factors of inflation convergence in the European Union

We provide comprehensive evidence of the widespread occurrence of inflation convergence between all countries of the European Union from 1999 to 2016. We also show that convergence was more inclusive in the years after the global financial crisis—including the European sovereign debt crisis and the period of zero lower bound—and that price-stabilityoriented monetary strategies might have in fact facilitated this convergence. Our results are robust with respect to the use of three inflation benchmarks (the cross-sectional average, the inflation target of the European Central Bank, and the Maastricht criterion), structural breaks, and a core inflation measure. Our main findings imply that further enlargement of the euro area is feasible from the perspective of the convergence of inflation rates between the countries of the European Union.
