Despite the increasing occurrence of part-time employment in Germany, the effects on wage rates are rarely studied. I therefore use GSOEP panel data from 1984 to 2010 and apply different econometric approaches and definitions of part-time work to measure the so-called part-time wage gap of both,...

This paper examines the impact of parental investments on various skills during childhood using the Mannheim Study of Children at Risk (MARS). Our work offers three important innovations. First, we use reliable measures of the child's cognitive, mental and emotional skills as well as accurate...

We study the effect of the introduction of the German statutory minimum wage law in 2015 on teenagers' educational expectations. We focus on low-skilled students, the group most likely to be affected by the minimum wage after entering the labor market. Theoretical predictions of the effect of...

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...

Die Erhebung "American Time Use Survey" belegt kleine, statistisch signifikante Unterschiede der tatsächlichen Arbeitszeit am Arbeitsplatz nach ethnischen Minderheiten in den USA. Minderheitsbedingte Differenziale der geleisteten Arbeit werden nach Berücksichtigung von einer großen Anzahl von...

In this paper a labor supply model with demand side rationing is estimated to analyze the economic policies that directly affect incentives to work as well as labor costs. The framework is applied to evaluate the employment effects of a federal minimum wage in Germany and the impact of employer-...

This paper analyses the causal effects of educational mismatch on wages, individual health and job satisfaction. As educational mismatch is subject to unobserved heterogeneity in all of these fields, different identification strategies are applied to derive causal effects. In the wage...

In this paper I investigate the causal returns to education for different educational groups in Germany. I circumvent potential drawbacks of IV by employing a new method by Klein and Vella (2010). In this approach identification is not based on instruments but on the presence of...

What is the value of basic skills in the German labor market which until recently was considered to be strongly regulated but has gained flexibility in the last 15 years? To answer this question, we examine the relationship between adults' literacy, numeracy and earnings. We use data from the...

Existing estimates of the labor-market returns to human capital give a distorted picture of the role of skills across different economies. International comparisons of earnings analyses rely almost exclusively on school attainment measures of human capital, and evidence incorporating direct...
