#GDRI_rep Update 9: We have been waiting a couple of months to make two announcements. A few journals were in the process of retracting GDRI article. The editors informed the authors and then lawyers got involved. Who knows how long it will take.

Paper is here. Demonstrates with a very large sample the same phenomenon we saw previously in a somewhat smaller sample in Ethiopia: list experiments can produce fleeing behavior that leads to negative prevalence rates

The answer to this excellent question from @kotsadam + Løvgren: yes! List experiments do not, in general, seem to be an effective tool for measuring IPV; we should not use them unless there is a convincing reason to think otherwise

1st update: We reproduced "Parent–teacher meetings and student outcomes" some time ago. The paper was then retracted by the editors of the Euro Econ Rev.

New preprint out with @aleksandermadsen.bsky.social, where we show that later-arriving childhood immigrants have lower earnings, are more likely to enter manual occupations, and are less likely to enter analytical and language-intensive jobs and be employed in high-wage firms as adults.

"It's the economy, stupid"
Voters vote based on the economy.
But there are many economic performance indicators. Which matter the most?
This new paper shows voters react to growth, unemployment, inflation, & stock markets.
But the inflation plays the biggest role.

Important paper from @anderskjelsrud.bsky.social and Sahar!
Female PhD students (in economics) benefit tremendously from having female faculty around.
When female professors go on leave, it decreases third-year female PhD students’ likelihood of publishing & securing academic positions.

Every authoritarian who successfully destroyed judicial independence did so because civil society failed to unite in time. The key difference? Whether people mobilized.

🧵 When authoritarian leaders attack judges as "enemies," history shows us exactly where this leads. Trump's assault on "USA HATING JUDGES" isn't just inflammatory rhetoric—it's following a script written by strongmen worldwide. But other countries show us how to fight back.
