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

#GDRI_rep Update 8a: Major updates coming up over the next few weeks.

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.

Additional studies are connected (see diagram)

Development aid can help suppress insurgencies, but it may be counterproductive in areas where insurgents came from outside of local communities, say researchers at @theworldbank.bsky.social, @mit.edu, and @upf.edu. #econsky www.aeaweb.org/research/dev...

Did development aid in Afghanistan help counter the Taliban’s insurgency?

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.

Do family-friendly hours make it easier for women politicians to participate in meetings? 🕚

In a new working paper, I find they don’t. 🧵1/10

Update #2, RETRACTED: 15 months after we (w @ollefolke.bsky.social and @johannarickne.bsky.social ) submitted the initial comment to the Journal, we've noticed the paper was ultimately retracted. Retraction note here: link.springer.com/article/10.1...

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.

After one year of waiting, we finally got a response from the Journal of Population Economics about our replication of "Banning the purchase of sex increases cases of rape: evidence from Sweden", confirming the major coding error that invalidates the main results, but not retracting the paper. 1/2

A re-analysis of Ciacci's (2024) "Banning the purchase of sex increases cases of rape: Evidence from Sweden" Journal of Population Economics reveals major issues. A year ago, reproducers Adema, Folke, and Rickne found coding errors driving the paper's key results. Let's unpack this in a 🧵

9/ Based on our initial and extended replications, we wonder: how can the editor still trust the results of this paper? If this case does not meet the criteria for retraction, what does?
