The Software Behind the Stats: A Student Exploration of Software Trends Across Disciplines

This paper presents a student-led activity designed to explore the use of statistical software in academic research across economics, political science, and statistics. Students reviewed replication files from major journals and repositories, gaining hands-on experience with reproducible workflows while contributing to cross-disciplinary datasets. Web-scraped metadata and student data collection, together covering more than 10,000 papers, reveal clear disciplinary patterns: Stata remains dominant in economics, while R is increasingly popular in political science and is the standard in statistics. Within the social sciences, a growing number of articles also use multiple software platforms within a single manuscript. Students reported increased understanding of academic workflows and greater awareness of software diversity in quantitative research. The activity is easy to adapt across course levels and disciplines, and we offer suggestions for follow-up assignments that reinforce key concepts in reproducibility and data fluency. The resulting insights into current software practices are also valuable for instructors seeking to align their teaching with evolving trends in research.

Recruitment, effort, and retention effects of performance contracts for civil servants: Experimental evidence from Rwandan primary schools

This paper reports on a two-tiered experiment designed to separately identify the selection and effort margins of pay-for-performance (P4P). At the recruitment stage, teacher labor markets were randomly assigned to a 'pay-for-percentile' or fixed-wage contract. Once recruits were placed, an unexpected, incentive-compatible, school-level re-randomization was performed, so that some teachers who applied for a fixed-wage contract ended up being paid by P4P, and vice versa. By the second year of the study, the within-year effort effect of P4P was 0.16 standard deviations of pupil learning, with the total effect rising to 0.20 standard deviations after allowing for selection.
