Katharina Wedel prepared this study while she was working at the Center for the Economics of Education at the ifo Institute. The study was completed in September 2023 and accepted as doctoral thesis by the Department of Economics at LMU Munich. It consists of four distinct empirical essays that...

This paper proposes a new strategy to identify causal effects. Instead of finding a conventional instrumental variable correlated with the treatment but not with the confounding effects, we propose an approach which employs an instrument correlated with the confounders, but which itself is not...

In this report we investigate the effects of vocational education and training (VET) on adult skills and labour market outcomes by using the PIAAC survey. Data comparability across countries, the breath of countries involved, and the almost unique presence of information on assessed skills,...

A lengthy literature estimating the returns to education has largely ignored the for-profit sector. In this paper, we offer some of the first causal estimates of the earnings gains to for-profit colleges. We rely on restricted-use data from the 1997 National Longitudinal Survey of Youth (NLSY97)...

We study the impact of student debt on various labor market outcomes, namely, labor market income, hourly wages, hours worked, and probability of full-time employment. Using data from the NLSY97 surveys and a difference-in-difference approach, we find statistically significant differences in...

Spence (1973) noted that individuals' choice of educational quantity — measured by years of schooling — may stem partially from a desire to signal their ability to the labor market. This paper asks if individuals' choice of educational quality — measured by college reputation — may...

On average, the parental practices adopted by African American parents of young children are much less cognitively stimulating than those of their white counterparts. This paper argues that these differences stem from the low rates of return to human capital historically experienced by African...

This article documents the long-term relationship among juvenile conviction, occupation choices, employment, wages, and recidivism. Using data from NLSY97, we document that youths who are convicted at or before age 17 have lower full-time employment rate and lower wage growth rate even after 10...

Numeracy skills of adults within and across 12 different countries in 2011 are strongly associated with the accumulated public investments in education received by these adults during their schooling. This paper confirms existing evidence that the timing of educational investments is important,...

Labor market institutions shape the return to workers’ skills. They define the incentives of firms and workers to invest in general and specific skills, affecting the returns to experience and tenure. This paper presents an empirical assessment of this hypothesis. We take advantage of rich...
