Does the Dispersion of Unit Labor Cost Dynamics in the EMU Imply Long-Run Divergence? Results from a Comparison with the United States of America and Germany

Abstract

Using unit labor cost (ULC) data from Euro area countries as well as US States and German Länder we investigate inflation convergence using different approaches, namely panel unit root tests, co-integration tests and error-correction models. All in all we cannot reject convergence of ULC growth in EMU, however, country-specific deviations from the rest of the currency union are more pronounced in Europe and more persistent. This holds before and after the introduction of the common currency.
