In labour markets with collective wage bargaining higher progressivity of the labour income tax creates a trade-off. On the one hand, wages are lowered and unemployment decreases, on the other hand, the individual labour supply decision is distorted at the hours-of-work margin. The optimal level...

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...

Changing the income tax progressivity in labour markets with collective wage bargaining generates a trade-off. On the one hand, higher progressivity distorts individual labour supply decisions at the hours-of-work margin, on the other hand, it reduces unemployment by exerting downward pressure...

This chapter reviews options of labour market modelling in a CGE framework. On the labour supply side, two principal modelling options are distinguished and discussed: aggregated, representative households and microsimulation based on individual household data. On the labour demand side, we...

Aufbauend auf der Hypothese, dass Arbeitsmärkte durch unvollständige Information charakterisiert sind, werden in diesem Arbeitspapier neuere Entwicklungen innerhalb eines Zweiges informationsökonomischer Ansätze vorgestellt: der Suchtheorie. Dabei werden ausführlich insbesondere jene...

We structurally estimate an equilibrium search model using German administrative data and use this for counterfactual analyses of a uniform minimum wage. The model with worker and firm heterogeneity does not restrict the sign of employment effects a priori and allows for different job offer...

This paper studies effects of the introduction of a new digital mass medium on reemployment of unemployed job seekers. We combine data on high-speed (broadband) internet availability at the local level with individual register data on the unemployed in Germany. We address endogeneity by...

Based on a structural model of fertility and female labour force supply with unobserved heterogeneity and state dependence, we evaluate the 2007 reform of parental leave benefits in Germany, which replaced a flat, means-tested benefit by a generous earnings-related transfer. The model predicts a...

Ziel dieses Beitrags ist die Quantifizierung der mit der Einführung des Arbeitslosengeldes II verbundenen Arbeitsangebots- und Beschäftigungseffekte. Zusätzlich wird ein Reformszenario simuliert, welches die Anreizstruktur im Niedriglohnbereich verbessern soll. Methodisch wird ein...

We estimate the effects of the reform of the German Unemployment Insurance that replaced the wage related Unemployment Assistance with an income maintenance program and stronger means testing. We model the tax-benefit system and use the Socio-Economic Panel. We estimate a discrete labour supply...
