It’s becoming clear the “paper” format is going to change. We treat each result as a small, portable claim (X→Y + how it’s supported) and stitch those claims into a graph. Major update to Paper with @trfetzer.com full code + data below. 👇

Great to see our paper -- with @trfetzer.com and @prashantgarg.bsky.social -- on local decline in the UK featured in this Guardian piece. www.theguardian.com/business/202...

Does science follow where people are sick and does it mobilize when outbreaks hit? @zhou-hy.bsky.social, @trfetzer.com and I answer just that in our revised paper. 1/ A short thread for highlights 👇

“When researchers randomly displayed these flood risk estimates to 18M people browsing Redfin, those who saw the feature were more likely to search for homes w/ low flood risk, according to a working paper published in the Nat’l Bureau of Economic Research last Nov*.”🧪 * www.nber.org/papers/w33119

This graph from @economist.com reveals a major pivot in #economics toward data and empirical work, with theory and modeling taking a back seat. The underlying data is open source at www.causal.claims 🏷️ @prashantgarg.bsky.social @trfetzer.com

Can we learn about world cultures through AI? It’s promising.

2/ Discipline matters. Social Sci (27%) and Arts & Human. (31%) lead the exodus; Med & Health lag (13%). Twitter signals (followers, PageRank, posting) predict migration better than h-index or citations. Take-away: Your Twitter presence, not your CV, determines if you jump ship.

An analysis of ~100,000 academics finds that a small subset of academics generate majority of social media posts. That vocal minority can skew how the public—and even journalists—infer “academic consensus,” potentially fueling false perceptions. www.nature.com/articles/s41...

Some interesting insights here, including that people are much more influenced by *people they follow* switching platforms than by their own *followers* switching platforms. Preprint: "Why Academics are Leaving Twitter for Bluesky" arxiv.org/abs/2505.24801

Combien de scientifiques ont quitté Twitter entre 2023 et 2025 ? Selon cette étude, 18% des universitaires sur 300 000 étudiés ont effectué une migration vers Bluesky. De plus, les chercheurs qui ont reconstruit leur réseau sur Bluesky restent significativement plus actifs et engagés. 1/2

When we started in June 20204, we thought we just learn use of private data and level of null results in economics. Since then, @thiemo and I have introduced the concept of “Knowledge Graphs” into economics.

New open-access data for econ nerds: Causal Claims in Economics 🔓 250k+ claims made in 45k papers and 69 variable over 1980-2024. Now free to download. 🥳 Details below

This matters especially for political and scientific communication, where actors from both communities actively engage. Not to go too far, how about the cool recent paper by @prashantgarg.bsky.social rashantgarg.bsky.social and @trfetzer.com , which explores this in depth: bsky.app/profile/pras...

New Paper! @prashantgarg.bsky.social @fdenker.bsky.social @abovet.bsky.social study the migration of academics from X to Bluesky 🦋 Please reach out with any comments, ideas, or questions! A thread by my prolific coauthor👇

Why academics are leaving Twitter for Bluesky. Bluesky users know. #econsky

US universities, filled with faculty much more liberal than general public, are getting targeted by the government. STEM scientists are more liberal than social sciences and humanities, and are ones targeted to most.

A large-scale study of academics’ tweets shows disparities in who shapes academic discourse and how it reaches the public. @prashantgarg.bsky.social @trfetzer.com @imperialcollegeldn.bsky.social @uni-of-warwick.bsky.social #AcademicTwitter #ClimateAction www.nature.com/articles/s41...

1/ 🚨 Hot off the press! Our study “Political Expression of Academics on Social Media” with @trfetzer.com is now peer-reviewed & live in Nature Human Behaviour @nature.com 🎉. Thread 👇

*record scratch* "Yup, that's me. You're probably wondering how I ended up in this situation."

People change social networks when their friends do.

Cool paper alert

Of course there's also the answer that Twitter/X got shit and is run by a neo-Nazi ket-head but this is still genuinely interesting.

Happy to share this paper. Full thread coming soon!

How economics has changed

Wait, what’s going on? Are we dying?

It was a pleasure to discuss some of my causal ML+text data papers with Patrick, Xuanli and AYEW!

While unfortunate for Harvard and perhaps US, it’s nice to see international academic community welcoming international students to their institutions.

Really enjoyed discussing business dynamism, market power and productivity with the economic measurement community @escoeorg.bsky.social today.

Our work on Causal Claims in Economics, covered by @economist.com, on article titled "What the failure of a superstar student reveals about economic?"

We are happy to welcome @prashantgarg.bsky.social this week @zbw-leibniz.bsky.social who has presented his paper on causal claims today.

Across 300,000 papers published in top 100 economics journals, more than 90% of claims use language that is causal while less than 10% are actually using causal inference methods.
