Ever stood in a supermarket aisle trying to work out whether the bigger pack is actually cheaper? When the larger package is more expensive per unit than the smaller one, it’s called a quantity surcharge. Madhura Banerjee and I looked for these in NZ supermarkets. 🧵

We also looked at whether surcharges were more common in richer or poorer neighbourhoods. We expected more in richer areas, but the data did not support that. If anything, our results pointed the other way.

One dollar each or three for five? Quantity surcharges in New Zealand supermarkets

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.…)

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…

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…

Are Female Teachers Better for Girls’ Education?

Girls’ success in school is critical to their personal futures and is an international development imperative. But what’s the best way to achieve that?

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!
