This paper examines the impact of tuition fees on graduation rates among high-school leavers. We analyse the introduction of fees in several German states in 2006-07 (around EUR 1,000 annually), using administrative microdata on all university graduates and a difference-in-differences approach....

We use a rigorous three-stage many-analysts design to assess how different researcher decisions—specifically data cleaning, research design, and the interpretation of a policy question—affect the variation in estimated treatment effects. A total of 146 research teams each completed the same...

This study evaluates the effectiveness of varying levels of human and artificial intelligence (AI) integration in reproducibility assessments of quantitative social science research. We computationally reproduced quantitative results from published articles in the social sciences with 288...

This study pushes our understanding of research reliability by reproducing and replicating claims from 110 papers in leading economic and political science journals. The analysis involves computational reproducibility checks and robustness assessments. It reveals several patterns. First, we...

To reduce cheating in written tests and exams, assessors often randomly vary the order of questions across students. However, little is known about the potential unintended side effects of question order. This paper examines whether randomizing students to start with an easier or harder question...

Providing replication code is an inexpensive way to facilitate reproducibility. However, little is known about the extent of replication code provision. Therefore, we examine the availability of replication code for over 2500 peer‐reviewed articles based on the German Socio‐Economic Panel...
