We just spent 6 months to add 1 figure to this paper. Some people said, "Couples aren't prioritizing men's careers. Men just have better earnings opportunities when moving."

Earnings effects of moves for couples on the left, singles on the right. Negligible gap between single men and women.
Event study coefficients that show that men's earnings rise more than women's among couples following a cross-commuting zone move (left panels). The pattern is muted or reverses among single men and single women (right panels).

Over the years my Econ 101 class has become much more empirically grounded.
We now discuss:
💘Experimental evidence on supply shocks in dating markets
🗳️How social preferences for redistribution shape voting
💊Unintended consequences of price collusion in the pill market🤰

🎉 Teaching Milestone 🎉
This semester, I’m teaching my 10,000th student in Econ 101 (Micro 1).
Over the past 8 years, it’s been a lot of fun and a privilege to teach the fundamentals of economics - scarcity, demand and supply, opportunity costs, game theory and externalities.

Die UZH bietet dieses Jahr erneut das Modul «Mentoring für die nächste Generation» an. 54 Studierende begleiten ein Jahr lang je ein Primarschulkind als Mentor*in, nehmen an interdisziplinären Vorlesungen zur Kinder- und Jugendentwicklung teil und setzen Theorie in die Praxis um.

🆕 RFBerlin Discussion Paper: @xshan.bsky.social, @ulfzoelitz.bsky.social, and Uschi Backes-Gellner provide first-time evidence that online instruction disproportionally harms the learning outcomes of women compared to men. www.rfberlin.com/network-pape...

Are these results new?
Our meta-analysis shows that we already knew that online instruction generally hurts performance (avg −0.20 SD), but with a median sample size of 491 observations, most prior work lacked the power to detect the hidden equity cost of online instruction.
ulfzoelitz.bsky.social
Why does online instruction disproportionally harm women? Survey & zoom attendance data show that women more strongly prefer in-person lectures. When assigned more online lectures, they perceive the course as less enjoyable, less comprehensible, and instructors as less engaging.
ulfzoelitz.bsky.social
The negative effect of online instruction on women is concentrated in math-intensive courses and lasting. Here, women exposed to more online earn fewer credits and become more likely to drop out of the program.
🚨🚨🚨
ulfzoelitz.bsky.social
For the first paper documenting a gender gap in the impact of online instruction, we must worry about the possibility of a false positive. It’s not! The gap remains highly precise after multiple-testing corrections (Bonferroni p=0.0036).
ulfzoelitz.bsky.social
More online instruction significantly lowers women’s performance, while leaving men’s unaffected. A 10 ppt shift toward online instruction decreases women’s exam score by 0.038 SD (p<0.001).

🚨 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♀️📉

I appreciate the multiple hypothesis testing reason for indices. But think of a meta-analysis that can't use the study b/c disaggregated results aren't shown.

I'd be fine if people just shared this post-publication.

(My use case: an index that combines women's gender attitudes and employment.)

When studies report results on indices that combine many vars, they should also show results for each var in the appendix. This is prompted by writing a review article; some studies have an index where only a subset of the vars are on topic for me. Plus the original vars have interpretable units.

A new paper by @xshan.bsky.social and @ulfzoelitz.bsky.social presents evidence from a randomised field experiment showing that peer groups can influence students’ conscientiousness, openness, and competitiveness - but have no spillover effects on extraversion, agreeableness, or neuroticism.

IZA has been a key player in shaping labor economics, fostering collaborations, and providing a valuable platform for Economists worldwide.

Hard to accept that IZA will simply vanish.

When cleaning up I found this old business card of mine. During the 3 years I worked at IZA/briq as a postdoc I had an incredible productive time and terrific colleagues.
