Perhaps surprisingly, in light of the Lucas critique, our principal finding is that there appears to be relatively little instability in the parameters of the Euro-area inflation process. Full-sample estimates of the persistence parameter are generally close to one, and we fail to reject the hypothesis that this parameter has been stable over time. We discuss how these results provide some indirect evidence against rational expectations models with strong forward-looking elements, such as the New-Keynesian Phillips curve.||Type of material:||Working Paper||Publisher:||European Central Bank||Series/Report no.:||Working Paper Series; No. 335||Copyright (published version):||Copyright Central Bank, 2004||Keywords:||Inflation persistence; Euro Area; Lucas Critique||Subject LCSH:||Inflation (Finance)--Europe
