Does gender diversity in peer groups benefit performance? I ran a 7-year field experiment with 3,000+ students to find out. Key findings: As gender diversity increases – Course grades in short & longer run ⬆️ – Dropout rates ⬇️ – Performance inequality in groups ⬇️ Details below🧵

🚨 New working paper! 🚨 We ran a field experiment with >1,300 university students randomly assigned to online vs in-person lectures. What happens? Online instruction hurts performance, but only for women♀️📉 with Xiaoyue Shan & Uschi Backes-Gellner www.ifo.de/DocDL/cesifo...

Come work with us at the National University of Singapore. Every year, we have a fantastic group of pre-docs working with us! #econ_ra fass.nus.edu.sg/ecs/pre-doc-...

@mdrouvelis.bsky.social and I co-edit a special section on experimental replications at European Economic Review. We are eagerly waiting for your replications of lab and online experiments. Please get in touch if you have any questions. #econsky

This paper sparked lively discussion in our seminar. Lots of excitement mixed with valid concerns. arxiv.org/abs/2411.10109
