Most studies find little to no effect of classroom computers on student achievement. We suggest that this null effect may combine positive effects of computer uses without equivalently effective alternative traditional teaching practices and negative effects of uses that substitute more...

Since 2007, the Ecuadorian government has required teacher candidates to pass national skill and content knowledge tests before they are allowed to participate in merit-based selection competitions for tenured positions at public schools in an attempt to raise teacher quality. We evaluate the...

In Germany and many other countries, students are tracked into various secondary school types. This paper studies whether parents or teachers assess students potential educational performance more adequately. Educational attainment is measured by grade retention rates. We take advantage of a...

The paper adds to the literature on extracurricular early childhood education and child development by exploiting unique data on an educational project in Germany, the Junior University (JU). By utilizing a quasi-experimental study design we estimate the causal short-term effect of JU enrollment...

Taxation changes the expectations of prospective university students about their future level and uncertainty of after-tax income. To estimate the impact of taxes on university enrollment, we estimate a structural microeconometric model, in which a high-school graduate decides to enter...

Western labor markets face major challenges caused by demographic changes. They increasingly experience a shortage of skilled workers and face the problem of an increasing disparity between a reduced group of active workers contributing to the pension scheme and a rising share of an older...

This paper investigates two mechanisms through which education may affect cognitive skills in adolescence: the role of instructional quantity and the timing of instruction with respect to age. To identify causal effects, I exploit a school reform carried out at the state level in Germany as a...

Online education options have proliferated in recent years, with significant growth occurring at state-sponsored virtual schools. However, there is no prior credible evidence on the quality of virtual courses compared to in-person courses in U.S. secondary education. We compare the performance...

I investigate whether faculty quality and department size affect the productivity of scientists. The endogeneity problems related to estimating these effects are addressed by using the dismissal of science professors by the Nazi government as a source of exogenous variation. While local faculty...

Following German reunification the East German states were confronted with the need to adapt their schooling system to quality criteria settled by the western states. Most importantly this included an extension of high school education by one year. We use this variation in high school duration...
