This year I joined the editorial team of @jcre.bsky.social, the Journal of Comments and Replications in Economics (JCRE) as a Co-Editor. I'm especially happy that the first submission I handled from start to finish has now been published—together with a reply from the original authors.

Congrats to @i4replication.bsky.social - very well deserved! But, @aufdroeseler.bsky.social, this is our award, too – right? Right? 😉 Good thing we are reproducing it this year @uni-muenster.de: bsky.app/profile/aufd... #mücos #cdsc

Congratulations to the project “Replication Games,” which received🏆2026 SIPS Mission Award! Replication Games builds community and skills for researchers in one-day hackathons to assess the reproducibility and robustness of published research. 🔗https://buff.ly/nXfbAO8

The debate about Borjas/Breznau's paper on ideological bias in migration research is out now @i4replication.bsky.social. With a comment by Katrin Auspurg & Josef Brüderl: hdl.handle.net/10419/341575 And a reply by the original authors: hdl.handle.net/10419/341576

@i4replication.bsky.social is doing a great job facilitating *debates* about methodology and scientific practises. One can read the arguments and make up their minds: much of the argumentation is made public (instead of being discussed among the editors or other small circles).

Happy to have the CBS Replication Games (and my replication research more broadly) featured on the ODISSEI Podcast! Tune in if you're interested in hearing @drtomemery.bsky.social and I nerd out over replication!

How can games change research culture? 🧩 On this month's ODISSEI podcast, @drtomemery.bsky.social talks with Jack Fitzgerald about replication, and why it needs to be more embedded in research. That's why the Replication Games were developed, Jack explains. 🎧 Tune in to learn more: edu.nl/eqhuc

The reply to our comment is now online at AEJ:Applied. The broader takeaway: should we trust an IV if removing coding errors requires a different first stage? www.mollylipscomb.com/_files/ugd/a...

New @i4replication.bsky.social DP: We replicated the seminal Lipsomb et al. paper on electrification in Brazil - and found consequential coding errors. Turns out the paper is based on a fragile IV. After many years, the replication is forthcoming in AEJ:Applied. www.econstor.eu/bitstream/10...

📢 Call for Papers! We are partnering with the Journal of Economic Surveys on a special issue: Reproducibility and Meta-Science in Economics. Submission deadline: 1 March 2027. Details in thread 🧵

We're having an amazing time at @mcgilluniversity.bsky.social. Our CAnD3 replication games today are focused on health! Huge thanks to Arianne Rodriguez-Saltron and Amélie Quesnel Vallée for organizing.

New DP @i4replication.bsky.social : An Empirical Assessment of Computational Reproducibility in Sociology. www.econstor.eu/bitstream/10...

This is a fantastic and rare (!) example of authors of a published paper and the author of a comment on that paper working together to fix the scientific record. Kudos to all involved. This is not easy, even with good faith all around. @droodman.bsky.social @i4replication.bsky.social #EconSky

🚨 CORRIGENDUM ALERT 🚨 A decade after Star Wars: The Empirics Strike Back was published in AEJ: Applied, we've just published an official corrigendum with the AEA. This is a love story. 🧵

The authors of the great Star Wars paper and I just posted a 1-page corrigendum. It does not change conclusions. Very fun working with my fellow Jedi meta-scientists. That I checked the work is a measure of the paper's importance. The Force aligned us.

We're having fun replicating papers today. Thanks to everyone participating to the Utrecht Replication Games!

Incentives to reproduce and replicate articles are so bad. Even when your comment leads to the retraction of a PLOS One article, the reward is a (10 days late) email with a thank you at the bottom. Retraction notice: journals.plos.org/plosone/arti.... But we are not complaining about PLOS One 🧵

Ongoing replication games at CERDI, Clermont-Ferrand and games yesterday at the Canadian Economic Association in Vancouver! Thanks to the local organizers (Simone Bertoli and Kevin Schnepel) and everyone one who participates! 2 more games within the next 10 days :)

All the more reason to be excited for the results of the second iteration of AI replication games that were held earlier this month: bsky.app/profile/i4re... (4/4)

🚨 New AI Games round is live 🚨 Our first AI Games paper is now out at a top general interest journal (see preprint here: www.econstor.eu/bitstream/10... So… we’re launching the next stage 👇

This is a great study and (one of?) the first of its kind! A note of caution from a human contributor though: given the slow academic publishing process, the findings should primarily be interpreted as a snapshot of AI capabilities (and the capabilities of researchers using AI) in 2024. (1/4)

1/ Can AI help researchers check whether published social science results actually reproduce? In our new PNAS paper, we tested this directly in the AI Replication Games: 288 researchers, 103 teams, and real replication packages from quantitative social science.

We are happy to announce the Best Article Award for 2025. This paper examines the impact of papers meant to help reassess previously published papers. These findings are important for our discipline to understand. Congrats to @jrgptrs.bsky.social, Nathan, and Florian! doi.org/10.1111/ecin...
