#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

#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?

Just reviewed for Mechanisms of Aging and Development, a respected journal w. IF>5, and found this in the acceptance letter: "This recommendation is primarily based on your esteemed standing in the academic community, rather than on the overall quality of the manuscript itself." What can you say?

#TeachEcon

This semester, I thought I’d share a bit about what I do in my microeconomics lectures. I’m not particularly active on LinkedIn, but I started posting about my teaching because I’m quite frustrated with how economics is often perceived at business schools. (1/n)

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 🧵

"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.

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.

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.
