After becoming a congressional leader, a politician’s stock portfolio beats out those of peers by 47 (!!!) percentage points a year through trades timed around bills and firms that later get government contracts www.nber.org/papers/w34524 via @florianederer.bsky.social

In light of record submission rates and a large volume of AI-generated slop, SocArXiv recently implemented a policy requiring ORCIDs linked in the OSF profile of submitting authors, and narrowing our focus to social science subjects. Today we are taking two more steps: /1

This is terrifying. "[AI agents] can... infer a researcher's latent hypotheses and produce data that artificially confirms them." ... "We can no longer trust that survey responses are coming from real people" [email protected]

NBER grants to fund research into economic measurement - I find this agenda very compelling and important #linkoftheday www.nber.org/news/nber-la...

Oof, this is super slick! Go check it out 👇🏻

This paper’s been popping as “evidence” that you can’t do real #causalinference w/ obs data. To me it shows you need rigorous pre-specified design (in addition to the willingness to fold when your hypothesis is not possible to answer with the data at hand). #EpiSky, #CausalSky, #AcademicSky

🚨Next time you hire, don’t take it easy! In a new working paper, @elliottash.bsky.social, Jason Sockin, and I show the difficulty of the interview signals to workers whether the job is a good fit. 🚨 Paper link: papers.ssrn.com/sol3/papers....

Do any other languages (Dutch, German, Spanish) share this quirk, or is English alone in having a verb whose past tense is an exact anagram of its base form?

Are there any other English verbs whose past tense is formed by simply rearranging the same letters (with no additions or deletions) as their present tense — like eat → ate? I can’t think of another example #NLP #linguistics

This study uses computational methods, including #AI, to analyze textbooks from public, religious private, & home schools, focusing on how they portray people, topics, & values over time. Read: papers.ssrn.com/sol3/papers.... Subscribe: www.ssrn.com/index.cfm/en... #AICommunity

Thanks for sharing @florianederer.bsky.social Now that’s art — a true masterpiece!

Now that school is starting for lots of folks, it's time for a new release of Speech and Language Processing! Jim and I added all sorts of material for the August 2025 release! With slides to match! Check it out here: web.stanford.edu/~jurafsky/sl...

I love this article by @briancalbrecht.bsky.social in the Wall Street Journal (and not just because I am graciously mentioned by name). He provides a simple but powerful defense of Economics, of the supply and demand framework.

APOLLO: “.. Nvidia now has the biggest weight in the S&P 500 of any individual stock since the data began in 1981.”

Peter Temin, economic historian at MIT, has passed away. He worked both on problems of understanding the past (e.g. "Did Monetary Forces Cause the Great Depression?") and how how the past shapes the present (e.g. "The Vanishing Middle Class.") Terrific scholar and mentor, generous critic.

Excessive screentime in early age associated with delayed cognitive development, both directly and indirectly through what it crowds out: play, talk, & exploration. But limited use seems fine.

Referees make the journal system work. They are selfless in volunteering their time to ensure that our science continues to progress. All of the great referees out there please know that editors recognize your hard work and tireless effort. We do not always say it, but we do! Thank you.

What a fantastic accomplishment -- and what a fantastic story! www.quantamagazine.org/at-17-hannah...

Statement from the largest economics association about the BLS firing As context: AEA approximately never makes such public statements This is a big deal

It has been the honor of my life to serve as Commissioner of BLS alongside the many dedicated civil servants tasked with measuring a vast and dynamic economy. It is vital and important work and I thank them for their service to this nation.

The AI arms race is accelerating as major tech companies add to their already gargantuan levels of spending. The bets are paying off for investors, but not for all employees.

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. 1/

If you read my work, I have always loved using em-dashes. Now I actually go through & replace them with semicolons or parentheses (even when dashes would be better) because people assume they are AI Reminds me of the great Delve Collapse - use of the word dropped after it became associated with AI.

Yellin' at Yellen - great new paper. “Congress interrupted Janet Yellen, the only woman to chair the Federal Reserve Board, far more than her male peers. We find that lawmakers with daughters did it less, suggesting gender bias drove the interruptions.” www.journals.uchicago.edu/doi/10.1086/...

Scrolling through a journal’s website to find your own published article just doesn’t hit the same as wandering into a bookstore and spotting your name on a spine. Same idea, less magic … #EconSky #Academia #Publishing

🧵 NEW PAPER - "Quantifying Narrative Similarity Across Languages" is live at SMR. We combine NLP w pairwise LLM evals to track ideas across media ecosystems and languages. We also figured out a way to eval unsupervised probs on widely understood supervised performance metrics.

Like I've said before, if you have any doubts about climate change, just go to a super-boring insurance conference and listen to the super-boring panels where they dryly talk about the growing threat of disasters so catastrophic and unpredictable in scope they simply cannot be insured at any price.
