New working paper! We ran a field experiment with >1,300 university students randomly assigned to online vs in-person lectures in first-semester courses. What happens? Online instruction hurts performance, but only for women♀️📉 wt @_XiaoyueShan_ @UschiBackes

New research alert! Our study investigates the effectiveness of human-only, AI-assisted, and AI-led teams in assessing the reproducibility of quantitative social science research. We've got some surprising findings!

We had games in Munich earlier this week. 60 participants reproducing 15 studies (3 econ, 4 poli sci and 8 psych articles)! Some papers did not reproduce, missing data/codes, 2x revealed identity of participants, errors, etc. A couple of thoughts from our chair (AB). 🧵

I’m very happy to introduce our new WP with @yveszenou1, @BhagyaGunaward5 and @sofoklis_goulas! We study the impact of being randomly assigned to a classroom with a same-gender top-performing student on short- & long-term educational outcomes. #EconTwitter @MonashBusiness

Job-market candidates: - Download 10 JMPs in your field, read them in ≤5 hours, and rank them from best to worst. Now you know why recruiting committees value readability. - Editing improves paper quality. See RCT: doi.org/10.1016/j.jebo.2023.… (More at jdingel.com/teaching/advice.…)

really important work!
How credible was the "credibility revolution"? How robust is empirical research in economics? We just replicated a year's worth of the American Economic Review & had economists predict robustness. Here's what we learned. econstor.eu/handle/10419/295…

In Taiwan, disadvantaged minorities lower student effort, parental investments, and teacher engagement in classrooms to which they are randomly assigned, and this lowers student test scores, from @adegendre, @chriskarbownik, @nsalamancaa, and @yveszenou1 nber.org/papers/w32429

It's great to see a meta-analysis and multi-country study verify more robustly what @ALeNestour & I observed in our quick @CGDev look at whether women teachers are better for girls' education (yes in secondary; no in primary): cgdev.org/blog/are-female-te…

Very impressive research by Jan and the team, which they just keep improving (I discussed a version of this paper two years ago and it was an epic then).

Our work with @AdeGendre, @chriskarbownik and @yveszenou1 combines a simple model and awesome data to show how and why disadvantaged minorities in the classroom to affect behaviors of students, parents and teachers, and ultimately test scores. Check it out!

New work with awesome coauthors @AdeGendre, @EconFeld and @uZoelitz exploring the generalizability of same-sex teacher effects by combining existing multi-country data and met analysis tools. Check out the thread below!

In secondary education, same-sex teacher effects are generally positive for all outcomes. For test scores, effects even appear constant (and tiny) across all included countries.

Taken together, our paper allows us to provide evidence for the following phenomenon: Same-sex teacher effects are positive in secondary education. “In secondary education” is a boundary condition of the phenomenon. It tells us where we should expect it to hold.
