In this paper we develop a structural model of female employment and fertility which accounts for intertemporal feedback effects between the two outcomes. We identify the effect of financial incentives on the employment and fertility decision by exploiting variation in the tax and transfer...

We estimate a dynamic structural life-cycle model of employment, non-employment and retirement that includes endogenous accumulation of human capital and intertemporal non- separabilities in preferences. Additionally, the model accounts for the effect of the tax and transfer system on work...

In this paper we use a dynamic structural life-cycle model to analyze the employment, fiscal and welfare effects induced by unemployment insurance. The model features a detailed specification of the tax and transfer system, including unemployment insurance benefits which depend on an...

This paper contributes to the debate about the optimal design of tax-transfer systems. Based on the theory of optimal taxation, combined with microsimulation and microeconometric techniques we derive the welfare function which makes the current German tax and transfer system for single women...

How can public pension systems be reformed to ensure fiscal stability in the face of increasing life expectancy? To address this pressing open question in public finance, we estimate a life-cycle model in which the optimal employment, retirement and consumption decisions of forward-looking...

Viele Regelungen im deutschen Arbeitsrecht gelten nur für Betriebe ab einer bestimmten Größe, wobei derartige Schwellen meist anhand der Beschäftigtenzahl bestimmt werden. Die bestehenden 160 Schwellenwerte sind komplex und inkonsistent definiert, was ihre Beachtung durch die Firmen...

Im deutschen Arbeitsrecht gibt es eine Vielzahl arbeitsrechtlicher Schwellenwerte. Diese geben an, ab welcher Mitarbeiterzahl ein Gesetz bzw. eine Regelung wie z. B. der Kündigungsschutz zur Anwendung kommt. Wie in der Arbeit gezeigt wird, erschweren unterschiedliche Definitionen der...

In dieser Arbeit werden Auswirkungen des deutschen Schwer-behindertengesetzes auf die Arbeitsplatzdynamik mit Daten der Bundesagentur für Arbeit und des IAB-Betriebspanels empirisch überprüft. Die Daten erlauben eine Untersuchung der zweiten Schwelle des Gesetzes von 25 Beschäftigten, bei...

In Germany, many labour laws and regulations apply only in establishments above a critical size, and usually these thresholds are defined by the number of employees. The existing 160 thresholds are complex and defined inconsistently, making it difficult for firms to obey the law. Moreover,...

In public discussion in Germany it is often argued that jobs are mainly created in small and medium-sized firms (i.e. the "Mittelstand"), whereas large firms tend to reduce their number of jobs. An empirical analysis for the period 1999 to 2005 with data of all western and eastern German firms...
