This paper offers a reappraisal of the inflation-unemployment tradeoff, based on ?frictional growth,? describing the interplay between nominal frictions and money growth. When the money supply grows in the presence of price inertia (due to staggered wage contracts with time discounting), the...

Dieser Beitrag analysiert die Existenz und das Ausmaß nach unten starrer Nominallöhne, sowie deren realwirtschaftliche Implikationen für den deutschen Arbeitsmarkt. Unter Verwendung von drei alternativen Modellvarianten für die proportionale Abwärtsnominallohnrigidität wurde auf Grundlage...

This paper introduces a form of boundedly-rational expectations into an otherwise standard New-Keynesian Phillips curve. The representative agent's forecast rule is optimal (in the sense of minimizing mean squared forecast errors), conditional on a perceived law of motion for inflation and...

We estimate the sticky information Phillips curve model of Mankiw and Reis (2002) using survey expectations of professional forecasters from four major European economies. Our estimates imply that inflation expectations in France, Germany and the United Kingdom are updated about once a year, in...

This paper introduces a form of boundedly-rational inflation expectations in the New Keynesian Phillips curve. The representative agent is assumed to behave as an econometrician, employing a time series model for inflation that allows for both permanent and temporary shocks. The near-unity...

This paper deals with a critical assessment and a reestimation of the "non-accelerating in ation rate of unemployment" (NAIRU) for Germany. There are quite a few obstacles to perceiving the NAIRU as an understandable and easy-to-use analytical instrument, suitable for economic policy: the...

We provide evidence on the fit of the hybrid New Keynesian Phillips curve for selected euro zone countries, the US and the UK. Instead of imposing rational expectations and estimating the Phillips curve by the Generalized Method of Moments, we follow Roberts (1997) and Adam and Padula (2003) and...

Inflation as a phenomenon has witnessed remarkable changes starting from mid-eighties of the last century. Inflation rates have become less persistent, less responsive to supply side shocks. In addition, the relative importance of demand pull inflation as one of the major determinants of...

This paper uses forecasts from the European Central Bank?s Survey of Professional Forecasters to investigate the relationship between inflation and inflation expectations in the euro area. We use theoretical structures based on the New Keynesian and Neoclassical Phillips curves to inform our...

This paper estimates variants of a small-scale New Keynesian model using observations on inflation, inflation expectations and nominal interest rates. We ask whether those variables alone can tell us something about the time series properties of real marginal costs.
