This study provides a comprehensive systematic review of recent randomized controlled trials (RCTs) to evaluate the employment effects of skills training programs in sub-Saharan Africa, a region where such interventions are a key element of development assistance. The review focuses on studies...

We analyze the effect of education on wages using German Socio-Economic Panel data and regional variation in mandatory years of schooling and the supply of schools. This allows us to estimate more than one local average treatment effect and heterogeneous effects for different groups of...

The Bologna Process aimed at harmonizing European higher education systems and at increasing their efficiency. This paper analyzes impacts of the Bologna Reform for Germany by using unique micro data from Humboldt-Universität zu Berlin (HU). We estimate treatment effects on the probability to...

The spell-based nature of the National Educational Panel Study poses some challenges for analyzing training participation rates across waves. Raw training participation rates of each wave using courses compiled in the SpCourses data set and in the SpEmp data set differ by up to 75 percent across...

Occupational mismatch is a wide-spread phenomenon among immigrants in many European countries. Mismatch, predominantly measured in terms of education, is often regarded as a waste of human capital. Such discussions, however, ignore the imperfect comparability of international educational degrees...

We use the European Community Household Panel, a harmonized data set covering the countries of the European Union, to provide detailed estimates of the returns to education. Our results can be summarized as follows. Firstly, average returns to education have been mostly stable during the second...

Individuals with more years of education generally acquire more training later on in life. Such a relationship may be due to skills learned in early periods increasing returns to educational investments in later periods. This paper addresses the question whether the complementarity between...

School entry regulations lead to differences in the age when children start school. While previous literature estimated the effects of age at school entry for compliers with school entry regulations, we look at non-compliers, namely those who enter school one year before the official entry date....

Low Emission Zones (LEZs) reduce local air pollution by restricting emission-intensive vehicles from accessing designated areas and have been shown to improve population health. Little is known about the effects of driving restriction policies on other areas of life. This paper studies the...
