Many university students depend on employment during their studies. The closing of universities and the loss of many typical student jobs during the COVID-19 pandemic particularly affected their situation. Based on survey data from a major German university, we analyze changes in students'...

We investigate the impact of student work experience on later hiring chances. To completely rule out potential endogeneity, we present a field experiment in which various forms of student work experience are randomly disclosed by more than 1000 fictitious graduates applying for jobs in Belgium....

Due to the prevalence and important consequences of student work, the topic has seen an increased interest in the literature. However, to date the focus has been solely on measuring the effect of student employment on later labour market outcomes, relying on signalling theory to explain the...

The theory of differential overqualification, developed by Robert Frank (1978), claims that married women in smaller labor markets have a higher risk of working in jobs for which they are overqualified. This stems from the problem of dual job search for couples which is much more difficult to...

We test the basic assumption underlying the job competition and crowding out hypothesis: that employers always prefer higher educated to lower educated individuals. To this end, we conduct a randomised field experiment in which duos of fictitious applications by bachelor and master graduates are...

To study the causal impact of smartphone use on academic performance, we collected – for the first time worldwide – longitudinal data on students' smartphone use and educational performance. For three consecutive years we surveyed all students attending classes in eleven different study...

Occupational mismatch, defined as a discrepancy between workers' qualifications or skills and those required by their job, is a highly debated phenomenon in developed countries, but rarely addressed in developing economies from a comparative perspective. This study investigates the magnitudes of...

University students' smartphone use has recently been shown to negatively affect their academic performance. Surprisingly, research testing the empirical validity of potential mechanisms underlying this relationship is very limited. In particular, indirect effects of negative health consequences...

This study assesses the relationship between sleep quality and academic achievement. We survey college students about their sleep quality by means of the Pittsburgh Sleep Quality Index (PSQI) before the start of their first exam period at university. PSQI scores are matched with course marks in...

We review the theories put forward, methodological approaches used, and empirical conclusions found in the multidisciplinary literature on the relationship between student employment and educational outcomes. A systematic comparison of the empirical work yields new insights that go beyond the...
