The incidence of Cesarean deliveries (CDs) has been on the rise. The procedure's cost and benefits are discussed controversially; in particular, since non-medically indicated cases seem widespread. We study the effect of CDs on subsequent fertility and maternal labor supply. Identification is...

We provide a novel interpretation of the estimated treatment effects from evaluations of parental leave reforms. Accounting for the counterfactual mode of care is crucial in the analysis of child out-comes and potential mediators. We evaluate a large and generous parental leave extension in...

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 model the bargaining process of parents over custody at the time of divorce. First we assume an institutional setting where only sole custody is available. In a second step we reform this institutional setting and introduce the possibility of joint custody. We show that some parents, who...

Maternity leave policies are presumed to be essential to ensure the health of pregnant workers and their unborn children. However, little is known about the optimal duration of prenatal maternity leave and existing policies are not evidence-based. We evaluate a substantial maternity leave...

For the design of the pension system, it is crucial to disentangle the employment responses related to the substitution effect and the income effect. In this paper, we provide causal evidence regarding the importance of the income effect, which is generally assumed to be small or non-existent....

We evaluate three policy reforms targeted at older unemployed people: (i) an hourly wage subsidy, (ii) an in-work credit, and (iii) a subsidy of social security contributions on low wages. The work incentive, labour supply and welfare effects of these hypothetical reforms are analysed on the...

Since September 2000, as a result of mobility restrictions, the supply of Palestinian workers competing for local jobs in the West Bank has increased by about fifty percent. This paper takes advantage of this unique natural experiment to study the effects of labor supply shocks on labor market...

This paper extends previous research about the determinants of reservation wages by analysing the effect of progressive income taxation on the ratio between reservation and net market wages. Based on micro data for Germany (SOEP) we show that joint income taxation in Germany which discriminates...

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...
