📣Help needed! We are trying to reach people outside Europe with our short survey on research graphs! Could you share the link with someone? Take the survey yourself? Thanks in advance!! 🙏🌷🙏 (Europeans still welcome, of course!) supsy.eu.qualtrics.com/jfe/form/SV_...

❗ Help needed ❗ Please take our 5-minute survey about interpreting research graphs 📈 And please help us share this post with lots of people 🤗

Take the survey here: supsy.eu.qualtrics.com/jfe/form/SV_...

Thank you!!

You can do this right now:

Think of a person who wrote a paper you love, whose work influenced or helped you, or has made your professional life better.

Search up their email address. Shoot them a quick email of thanks. It means so, so much. This is a rough time of year, share some joy.

I used to think that people use the “weasel word causal inference strategy” (“our analyses show that X is an important predictor of…” followed by conclusions that are clearly causal) for the sake of plausible deniability. But I’m revising that now, because often deniability *isn’t* plausible.>

I've been working on a new tool, Refine, to make scholars more productive. If you're interested in being among the very first to try the beta, please read on.

Refine leverages the best current AI models to draw your attention to potential errors and clarity issues in research paper drafts.

🚨I4R is looking to hire postdoc fellows in public health and computer science!

The postdoc will join a team of researchers and help mass reproduce studies in leading public health journals or develop AI replicator agents.

Info 👇

happy 3²/4²/5² to ask those who celebrate

Teams are matched by expertise and pick from a curated list of top-journal studies. Learn more about the Institute for Replication: i4replication.org

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...

Peer reviewers more likely to approve articles that cite their own work Preprint examines how citations can influence the review process.

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!

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.

Call for Papers: Special Issue on the Science of Scaling We are excited to announce a special issue dedicated to the “Science of Scaling†in the Journal of Political Economy: Microeconomics. This special issue aims to advance rigorous, interdisciplinary

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:

🚨 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♀️📉

2025 Labour Econometrics Workshop The Melbourne Institute is proud to present the 27th Labour Econometrics Workshop.

Don't forget to submit your papers to the Labour Econometrics Workshop! The deadline is in two weeks ✌️

Hope to see you in Melbourne! 🌈🏙️

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!!!!! 🥳🥳🥳🥳🥳🥳

Now back home to New Zealand 🇳🇿 – excited for the summer weather ahead
