When grades lose their informative value because the percentage of students receiving the best grade rises without any corresponding increase in ability, this is called grade inflation. Conventional wisdom says that such grade inflation is unavoidable since it is essentially costless to award...

We benefit from the Bologna reform to show how course and program policies affect academic achievement. We examine two similar programs at the business school of a major European university, which were both reformed. Time lags in the reforms allow us to estimate the difference in the differences...

This paper examines field experiment in which we encourage the use of computer-based tests (quizzes) through a set of non-financial incentives and test their effect on effort and performance of students. Our identification strategy exploits cross-cohort experimental variation in assessment rules...

We use the recent introduction of tuition fees at public universities in seven of the sixteen German states to identify the effects of tuition fees on university enrollment of first-year students at German public universities. Our study differs from previous research in two important ways....

Survey data for a large sample of recent graduates from 37 German universities are used to study labor market outcomes of highly skilled young women and immigrants. Our results indicate a systemic wage gap for women, but not for male immigrants. We find no evidence that female immigrants suffer...

This study analyses the effect of an increase in college costs on student achievement, particularly time-to-degree and performance. I exploit a unique policy at a Swiss university to identify and estimate the causal effect of an increase in tuition. Students faced an unexpected raise in tuition....

This study explores the reduction potential of greenhouse gases for major pollution emitting countries of the world using nonparametric productivity measurement methods and directional distance functions. In contrast to the existing literature we apply optimization methods to endogenously...

Based on the seminal paper of Farrell (1957), researchers have developed several methods for measuring e fficiency. Nowadays, the most prominent representatives are nonparametric data envelopment analysis (DEA) and parametric stochastic frontier analysis (SFA), both introduced in the late 1970s....

Given the ambiguous empirical results of previous research, this paper tests whether support for a climate policy induced pollution haven effect and the pollution haven hypothesis can be found. Unlike the majority of previous studies, the analysis is based on international panel data and...

We study the relation between workers’ age and their productivity in work teams, based on a new and unique data set that combines data on errors occurring in the production process of a large car manufacturer with detailed information on the personal characteristics of workers re-lated to the...
