A number of authors have recently emphasized that the conventional model of unemployment dynamics due to Mortensen and Pissarides has difficulty accounting for the relatively volatile behavior of labor market activity over the business cycle. We address this issue by modifying the MP framework...

Benefit sanctions imposed on non-compliant welfare recipients are a new element in the German welfare system. In practice, the sanction policy and the application of sanctions vary considerably across the 439 welfare agencies. Based on combined administrative and survey data, these differences...

Primero enseñaremos que la (nueva) curva de Phillips diseñada por la escuela del «Nuevo Keynesianismo» se puede transformar fácilmente en una curva de Phillips «clásica». Teniendo en cuenta el «mismatch» en los mercados laborales, como lo describe la curva de Beveridge y combinando...

We develop a tractable macroeconomic model with employment risk and labor market search in order evaluate the effects of labor market reform on unemployment, growth, and welfare. The model has a large number of risk-averse households who can invest in risk-free physical capital and risky human...

The 2005 reform of the German welfare system introduced two competing organizational models for welfare administration. In most districts, a centralized organization was established where local welfare agencies are bound to central directives. At the same time, 69 districts were allowed to opt...

Whereas the standard modern theories of unemployment were developed in the context of a single sector labour market, this paper presents a survey of how these theories can be integrated into a dual labour market setting. This approach dichotomises the labour market into two sectors, a primary...

This work refers to analyses of matching processes on occupational labour markets in Germany. Up to now, all studies in this field are based on the crucial assumption of separate occupational labour markets. I outlined some theoretical considerations that occupational markets are probably not...

This paper makes use of data from the German socio-economic panel to gain new insights into the determinants of unemployment duration in Germany. Due to substantial differences with respect to labour market outcomes we follow a stratified approach with respect to gender and ethnicity. To analyze...

International Outsourcing effects on labor markets are mostly analyzed within flexible wage settings. Using a modern duality approach, this paper formally investigates differences occurring in industries with low skilled wage rigidity and, for the first time in literature, presents empirical...

We develop a model of directed technological change, frictional unemployment and migration to examine the effects of a change in skill endowments on wages, employment rates and emigration rates of skilled and unskilled workers. We find that, depending on the elasticity of substitution between...
