While consumption habits have been utilised as a means of generating a hump shaped output response to monetary policy shocks in sticky-price New Keynesian economies, there is relatively little analysis of the impact of habits (particularly, external habits) on optimal policy. In this paper we...

This paper takes a first step in analysing how a monetary union performs in the presence of labour market asymmetries. Differences in wage flexibility, market power and country sizes are allowed for in a setting with both country-specific and aggregate shocks. The implications of asymmetries for...

How does international integration affect the welfare state? Does it call for a leaner or an expanded welfare state? International integration may affect the distortions caused by welfare state activities but also the risks motivating social insurance mechanisms. This paper addresses these...

Is time-varying firm-level uncertainty a major cause or amplifier of the business cycle? This paper investigates this question in the context of a heterogeneous-firm RBC model with persistent firm-level productivity shocks and lumpy capital adjustment, where cyclical changes in uncertainty...

This paper presents a reappraisal of unemployment movements in the European Union. Our analysis is based on the chain reaction theory of unemployment, which focuses on (a) the interaction among labor market adjustment processes, (b) the interplay between these adjustment processes and the...

Using a German firm-level data set, this paper is the first to jointly study the cyclical properties of the cross-sections of firm-level real value added and Solow residual innovations, as well as capital and employment adjustment. We find two new business cycle facts: 1) The cross-sectional...

The aim of this paper is to analyze and estimate salient characteristics of unemployment dynamics. Movements in unemployment are viewed as "chain reactions" of responses to labor market shocks, working their way through systems of interacting lagged adjustment processes. In the context of...

We quantify the role of contractionary monetary shocks and wage rigidities in the U.S. Great Contraction. While the average economy-wide real wage varied little over 1929-33, real wages rose significantly in some industries. We calibrate a two-sector model with intermediates to the 1929 U.S....

The aim of this paper is to analyze and estimate salient characteristics of unemployment dynamics. Movements in unemployment are viewed as "chain reactions" of responses to labour market shocks, working their way through systems of interacting lagged adjustment processes. In the context of...

The main characteristic of the implementation of the European Monetary Union (EMU) is the transition from various national currencies to the Euro, the common European currency. A final fixing of the individual bilateral exchange rates of all European countries involved in the Monetary Union...
