happy 3²/4²/5² to ask those who celebrate

Wellington Replication Games — Dec 4, 2025 One-day team challenge to reproduce top social-science studies; co-authorship on a meta-paper; virtual welcome. Researchers, postdocs, PhDs — sign up: www.surveymonkey.ca/r/RB6K73Q #OpenScience #Metascience @i4replication.bsky.social

Hey #EAAE2025: Thursday is replication day. First, Anna Dreber's keynote on "Predicting Replication Outcomes" (11am) & our session👇(4pm) feat. ‪@robertfinger.bsky.social‬ @cedricchambru.bsky.social‬ @jensrommel.bsky.social‬ ‪@beta1hat.bsky.social‬ @mabuchner.bsky.social‬ ‪@i4replication.bsky.social‬

Good to see growing support for abduction or 'inference to the best explanation', recently by Spirling and Stewart in @thejop.bsky.social. This is... www.journals.uchicago.edu/doi/full/10....

Reviewers are more likely to approve manuscripts if authors agree to cite their work than those who don't get cited. Thanks to @aidybarnett.bsky.social, @balazsaczel.bsky.social and @econfeld.bsky.social for chatting with me for this story! www.nature.com/articles/d41...

Once upon a time, two science journalists had an idea for a blog about retractions. And on Aug. 3, 2010, Retraction Watch launched. And now, 15 years and 6,700 posts later, that work seems more important than ever. Happy 15th anniversary, Retraction Watch.

Interesting read, but worth considering (as the article does) the selection bias introduced by a) who is willing to initiate an adversarial collaboration and b) who manages to compete and publish it.

Our special issue seeks to foster novel theoretical and empirical papers that treat scaling as an object of study in its own right—exploring its methodological foundations, economic incentives, institutional challenges, and pathways to impact. Please spread the word! ideas.repec.org/p/feb/artefa...

Today, scaling has evolved far beyond its origins as a mere objective. It now represents a rich domain for scientific inquiry, demanding contributions from economics and allied disciplines. As such, I am excited to announce a special issue on scaling at the JPE-Micro!

Not balanced in your (quasi-)experiment? No idea why? No problem! Looking forward to presenting this joint work with @adegendre.bsky.social tomorrow at UWA Econ in Perth. Drop by if you have the chance!

The call for proposals is now up for our long awaited #AIMOS2025 conference in Sydney this November: aimos-inc.github.io/aimos.confer...

You can read the full paper here: www.ifo.de/DocDL/cesifo... Shan, Zölitz & Backes-Gellner (2025). "Disconnecting Women: Gender Disparities in the Impact of Online Instruction" CESifo Working Paper #11997.

🚨 New working paper! 🚨 We ran a field experiment with >1,300 university students randomly assigned to online vs in-person lectures. What happens? Online instruction hurts performance, but only for women♀️📉 with Xiaoyue Shan & Uschi Backes-Gellner www.ifo.de/DocDL/cesifo...

And if you are working in or interested in metaresearch in Australia, we'd love to hear from you! Fill out this brief @aimosinc.bsky.social @ausrepro.bsky.social survey so we can connect like-minded researchers. qualtrics.flinders.edu.au/jfe/form/SV_... 3/3

Join us @rwi.bsky.social & @i4replication.bsky.social as replicator for a meta-reproduction on deforestation. We pay replicators 2,500 EUR. Experience with geocoded data & background in environmental science are assets. 1/2 bit.ly/4ke2p6o

Don't forget to submit your papers to the Labour Econometrics Workshop! The deadline is in two weeks ✌️ Hope to see you in Melbourne! 🌈🏙️ melbourneinstitute.unimelb.edu.au/conferences/...

After a long wait, the working paper for the Many-Economists Project: The Sources of Researcher Variation in Economics. We had 146 teams perform the same research three times, each time with less freedom. What source of freedom leads to different choices and results? papers.ssrn.com/sol3/papers....

New research alert! Our study investigates the effectiveness of human-only, AI-assisted, and AI-led teams in assessing the reproducibility of quantitative social science research. We've got some surprising findings!

Another R&R with @nsalamanca.bsky.social @econfeld.bsky.social and @ulfzoelitz.bsky.social What a week!!!!! 🥳🥳🥳🥳🥳🥳

What an incredible 6 months at @iza.org – for me and my family! I’m so thankful for: 🤝 The kind and insightful IZA team who made us feel at home 📚 Inspiring workshops, conferences, and seminars 🌊 A stunning location next to the Rhein, with easy access to other research hubs Thank you, IZA!

We are very excited to welcome @econfeld.bsky.social to our #ResearchSeminar today. He will give a talk on “On the generalizability of sex-differences in risk-attitudes”. The seminar takes place from 14:15 to 15:30 in room S3/4 in the Oeconomicum (building 24.31). janfeld.weebly.com

Now heading to UNSW for ESCoE conference to present « Same-sex teacher effects in education » with @econfeld.bsky.social @nsalamanca.bsky.social @ulfzoelitz.bsky.social — paper here 👉🏽 adegendre.github.io/papers/deGen... — we even made a website with interactive effects ! www.role-model-effects.com

One single study is never enough. Check out this short piece by my friend and coauthor @econfeld.bsky.social on meta-science applied to Econ problems. I love the way he takes the reader by the hand and tell us his humble story.👇🏽👇🏽👇🏽 www.wgtn.ac.nz/business/res...

"Other researchers began citing our work as evidence of a universal truth... This interpretation was flattering but misleading." See my discussion on why one study is not enough here: www.wgtn.ac.nz/business/res...

New blog post! If you're a substantive researcher, you mainly do statistics to answer substantive questions. So let's stop putting the statistical model first. www.the100.ci/2024/08/27/l...

Regression: it's not just for causality! Spirling & Stewart argue it’s the tool for uncovering the best explanations. Think of it as detective work—solving the mystery of social data, one regression at a time. github.com/ArthurSpirli...

Our paper “Re-examining the relationship between patience, risk-taking, and human capital investment across countries” is now out in the Journal of Applied Econometrics. doi.org/10.1002/jae....   This study is one of the many replications part of the recent meta paper by @i4replication.bsky.social

Our first meta paper is out!! This paper combines our first 110 completed reproductions/replications. This is joint work with 350+ amazing coauthors. We summarize our findings below: econpapers.repec.org/paper/zbwi4r...

We are opening registration for the Australian Replication Games! Deakin University, Melbourne June 7th University Technology, Sydney June 11th We are looking for researchers, faculty and graduate students interested in a reproduction/replication challenge!

“six hours worth of work on the writing–done by an outside nontechnical editor who probably didn’t fully understand the technical economics–led to economist-readers believing that the paper was of higher quality.” Lots of good specific advice at the end for how to improve writing.

14th International Workshop on Applied Economics of Education (IWAEE) - call for papers open. 23rd to 25th June, 2024 - Catanzaro, Italy Keynotes: @dynarski.bsky.social, Brian Jacob and Sarah Turner. Submissions via iwaee.org Deadline end february

Lots of excellent news in the world of meta-science, especially in psychology. Amazing stuff happening at the editorial board of Psychological Science under the leadership of @simine.com @tomhardwicke.bsky.social !! This is the way forward to create and strengthen trust in scientific findings.

Very excited that @i4replication.bsky.social is going to be doing annual stress tests of papers published in Psych Science. It’s amazing to see what they’ve done in econ & poli sci, and great that they’re expanding to psych!

We are excited to announce that we will now reproduce and replicate studies in the fields of psychology and behavioral sciences!! We are also welcoming 13 new board members. 🧵with details below!

We are thrilled to announce a new collaboration with Psychological Science. Papers published in PS following January 1st, 2024 will be candidates for I4R to computationally reproduce, stress-test and replicate.

cool stuff!

I am very very happy to see this paper by @econfeld.bsky.social out! Writing does matter, in quantifiable and important ways. We should all invest more in learning how to do it better.

This is important new experimental work by my brilliant coauthor @econfeld.bsky.social showing that the quality of our writing matters a great deal for our research — eg getting into conferences, getting reports and R&Rs from journals, grants…
