Given the occasion, here is the newest version of our expert survey on the Acemoglu et al. vs. Albouy debate. Key finding is that even now, more than 10 years down the road, there is no consensus in the econ community about who was right in that debate 1/3 uni-due.de/imperia/md/conten…

You agree to the retraction, but "the factor structure originally reported in the article has been replicated in multiple language versions of the CRAVE using independent samples"
That’s great. Can you share the data and codes for these other articles?

One of us thought it would be a good idea to check the original authors’ public git history. We found deleted data…

Our chair and a few replicators investigated a paper about elite footballers. And missed the bigger story.
An independent researcher showed us what we had failed to see.
This is I4R’s CRAVE–football investigation. It starts with a PNAS paper.

Bachmann: Beschimpfen & Blocken. Der mediale Erfolg dieser Triple-B-Strategie ist schon wirklich bemerkenswert.

IMHO we'll struggle to distinguish between "negligently sloppy" & "intentional fabrication" as long as journals accept replication packages with analysis-ready data.

We have another @I4Replication report on #GDRI_rep. This time we replicate a paper originally published in the Economic Journal. Author responses can be found in the appendix. econstor.eu/bitstream/10419/…

New @I4Replication DP: How likely is a significant finding to replicate in a study of the same size? Replication probabilities are low for just-significant findings. In experimental economics, a result at p=0.05 has about a 25% chance of replicating. econstor.eu/bitstream/10419/…

My article on the "China shock" narrative of Autor et al. is out in Econ Journal Watch today. 1/6

The Bilal and Kanzig team is writing highly influential work about the long run costs of climate change. I have updated my comment on their QJE paper to include my thoughts on their new mortality paper. My goal is to stimulate debate

We scrutinize the robustness of evidence on carbon pricing. A first replication entering our analysis: The estimated effect of Finland’s carbon tax is statistically significant only when fuel-tourism Luxembourg is part of the synthetic-control donor pool. econstor.eu/bitstream/10419/…

Donor pool composition is the best way to get the result you want from the synthetic control method. Make a note of it.

Over the past two years, I4R partnered with Psychological Science on a large reproducibility project.
67 independent teams reproduced 64 articles published in 2024–2025, about 44% of eligible papers.

Here's what we learned 🧵

Some "overdue" news: my first paper on palm oil, started over a decade ago, was accepted for Christmas and is in print open access at the @JIntlEcon today. It's quite different from earlier versions, and the (excellent) review process improved it a lot.

Again, our criticism here is NOT directed at the REStat editors. We thank them for pursuing this and ultimately publishing the relevant record. The concern is at the publisher level (MIT Press). If legal pressure can stop or indefinitely derail a retraction that...
