In this paper we develop a dynamic structural life-cycle model of labor supply behavior which fully accounts for the effect of income tax and transfers on labor supply incentives. Additionally, the model recognizes the demand side driven rationing risk that might prevent individuals from...

Fungibility of money is a central principle in economics. It implies that any unit of money is substitutable for another and that the composition of income is irrelevant for consumption. We find in a field experiment that even in a simple, incentivized setup many subjects do not treat money as...

We analyse preferences for public, private or mixed provision of childcare theoretically and empirically. We model childcare as a publicly provided private good. Richer households should prefer private provision to either pure public or mixed provision. If public provision redistributes from...

Mircrosimulation models (MSM) and Computable General Equilibrium models (CGE) have both been widely used in policy analysis. The combination of these two model types allows the utilisation of the advantages of both types. The aim of this paper is to describe the state-of-the-art in simulation...

Fostering and supporting start-up businesses by unemployed persons has become an increasingly important issue in many European countries. These new ventures are being supported by various governmental programs. Potential benefits include not only the end of unemployment for the new entrepreneur...

For Germany, we analyse the (relative) effects of participation in several active labour market programmes on the employment prospects of participants. First, our results show that different matching algorithms result in different severe problems of common support. Second, we obtain favourable...

Our paper estimates the average effect of wage subsidies - paid to employers for a limited period of time - on the labour market prospects of needy job-seekers without access to insurance-paid 'unemployment benefit I'. The results show that wage subsidies had large and significant favourable...

Die Ich-AG (Existenzgründungszuschuss) war eines der zentralen Instrumente, das im Rahmen der "Hartz-Reformen" in den arbeitsmarktpolitischen Kanon aufgenommen wurde. Zusammen mit dem bereits seit langem bekannten Überbrückungsgeld wurden damit zwischen 2003 und 2006 mehr als eine Million...

In this paper we develop a discrete model of optimal taxation of married couples and empirically discuss the optimality of income taxation for this group. To this end, we derive the social welfare function which guarantees that joint taxation of married couples is optimal. We will contrast this...

Labor market programs may affect unemployed individuals' behavior before they enroll. Such ex ante effects are hard to identify without model assumptions. We develop a novel method that relates self-reported perceived treatment rates and job-search behavioral outcomes, like the reservation wage,...
