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...

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...

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...

We investigate the effectiveness of European Structural Funds on employment, population and house prices in Local Labor Markets (LLM) located in Southern Italy. We exploit the variability in disbursements between 2007 and 2013 and estimate the impact of the interventions by allowing for...

The impact of robots on employment and trade is a highly discussed topic in the academic and public debates. Particularly, there are concerns that automation may threat jobs in emerging countries given the erosion of the labour cost advantage. We provide evidence on the effects of robots on...

The empirical evidence on the incidence of payroll taxation is primarily based on the wage bill of firms. This paper applies matched employer-employee register data on individual wages for all private sector workers in Norway. Exploiting a payroll tax reform and using the...

This paper examines the effect of an expansion of subsidized early child care on maternal labor market outcomes. It contributes to the literature by analyzing, apart from the employment rate and agreed working hours, preferred working hours. Semi-parametric difference-in-differences estimation...
