There is a successful and growing number of studies published in top-economics journals that exploit the division and re-unification of Germany as a natural experiment for analysing the effects of political regimes on economic behaviour. One strand of the literature shows that socialism shaped...

This paper studies the causal effect of giving first birth and how that effect changes by the 2007 reform in parental benefits in Germany. We further investigate how the reform affects the selection of women into motherhood and how that selection effect affects labor market outcomes. A large...

The public economics, environmental, transportation and urban economics literature applies different labor supply approaches when studying economic or planning instruments. Some studies assume that working hours are endogenous while the number of workdays is given, whereas others model only...

We analyse a model in which families may either be “traditional” single-earner with caring for the child at home or “modern” double-earner households using market child care. Family policies may favour either the one or the other group, like market care subsidies vs. cash for care....

We estimate the labor force participation (LFP) response to the introduction of means-tested minimum pensions in the UK through the Old-Age Pension Act (OAP) of 1908. The OAP was a major social policy intervention and the first one to universally target older workers in a time of very limited...

I investigate causal machine learning (CML) methods to estimate effect heterogeneity by means of conditional average treatment effects (CATEs). In particular, I study whether the estimated effect heterogeneity can provide evidence for the theoretical labour supply predictions of Connecticut's...

This paper examines the effect of a program that extended the length of a school day to improve schooling quality in Mexico, on school enrollment, time spent on schooling activities, and child labor of children aged 7 to 14. We take advantage of the staggered implementation of the FTS program...

We analyse the effect of a mandatory kindergarten for four-year-old children on mothers' labour supply in Switzerland. Since education policy is regulated on a federal level, we exploit spatial variation as well as staggered implementation. Using a difference-in-differences approach, we find an...

This paper studies how the statutory right to work part-time affects mothers' post-birth labor market outcomes and higher-order fertility. I use a differences-in-differences design to investigate the introduction of a German law in 2001 that grants the right to work part-time to employees...

We develop the case of two-stage least squares estimation (2SLS) in the general framework of Athey et al. (Generalized Random Forests, Annals of Statistics, Vol. 47, 2019) and provide a software implementation for R and C++. We use the method to revisit the classic application of instrumental...
