By using a model of trade union behaviour Grüner (2010) argues that the introduction of the European Monetary Union (EMU) led to lower wage growth and lower unemployment in participating countries. Following Grüner's model, monetary centralization lets the central bank react less flexibly to...

This paper studies the role of long-term unemployment in the determination of prices and wages. Labor market theories such as insider-outsider models predict that this type of unemployed are less relevant in the wage formation process than the newly unemployed. This paper looks for evidence of...

A slanted-L curve is well-suited to represent the non-linearity of the celebrated Phillips curve. We show this using cross-country data of major industrialized economies since 2009, including the inflationary surge of the 2020s. At high unemployment rates, an increase in demand reduces...

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...

The objective of this paper is to provide an optimizing model of wage and price setting consistent with U.S. data. The paper first investigates the predictions of an optimizing labor supply model for the aggregate nominal wage, taking as given the evolution of prices and quantities. In this part...

This paper investigates the predictions of a simple optimizing model of nominal price rigidity for the dynamics of inflation. Taking as given the paths of nominal labor compensation and labor productivity to approximate the evolution of marginal costs, I determine the path of prices predicted by...

This study analyzes how competition affects price stickiness at the micro level. On the theoretical side, I develop what I call a micro Phillips curve, i.e. a product-specific relation between inflation and economic activity conditional on inflation expectations. I find two opposing effects of...

Persistently high unemployment rates in Germany have led to a long-running controversy on the causes of the unemployment problem. This paper aims to re­view the contribution of Keynesian and monetarist theories to this controversy and explores empirically their implications for the explanation...

This paper analyses the Nairu in the Euro Area and the influence that monetary policy had on its development. Using the Kalman-filter technique we find that the Nairu has varied considerably since the early seventies. The Kalman-filter technique is applied here for the first time using explicit...

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...
