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...

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...

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...

We analyse the effect of a mandatory kindergarten for four-year-old children on maternal labour supply in Switzerland by using two quasi-experiments: Firstly, we use a large administrative dataset and apply a non-parametric Regression Discontinuity Design to evaluate the effect of the reform at...
