Am reading « Why we sleep » by the brilliant @sleepdiplomat.bsky.social and loving it! Highly highly recommend! Will dive into the podcast next!

"genAI" doens't "learn" (tech execs' term) since it has no brains. Instead, it stores and regurgitates - PLAGIARISM.... "many AI developers use a more technically accurate term when talking about these models: lossy compression."

Disgraceful.

Read this if you don’t see the legal issues with or wonder about the legality of US actions in Venezuela

Can’t believe European leaders are discussing legality of US invasion of Venezuela. A summary of US actions in Venezuela: Kidnapping a citizen in their own country Expropriating their natural resources Seizing power until somebody deemed adequate is found. Who is next: Canada, Greenland?

Places Trump has said he wants to take over: Gaza Venezuela Mexico Canada Panama Canal Greenland U.S. blue cities & said he kept troops in Syria to "keep the oil." www.politico.com/news/2019/11... & said in 2016 that taking Iraq oil wouldn't be stealing. www.theguardian.com/us-news/2016...

That is called corruption. Let’s call things what they are.

Good to know for people who use LLMs for their R code

Myth busting in action ! @joshua-goodman.com & Joseph Winkelman wrote a great paper on trends in US college enrollments and debunk the narrative we’ve been seeing everywhere about students massively leaving higher education — please journalists read this 🔗 docs.iza.org/dp18285.pdf

A chilling reminder of the state of the Econ profession for women and the long road ahead towards what the profession should be

Entshittification — today we’ve had it with Netflix. Now we can’t even use Chromecast. This blogpost sums it up. « Netflix - like Airbnb, Uber, and the rest of the share economy from the 2010s - just isn't what it used to be anymore. » www.whistleout.com.au/PayTV/News/w...

Keep an eye on this JMC, fascinating work in Econ of education.

Holy shit. So Elon decides it would be nice to know what region of the world people are posting from. So they add that little feature. 2 hours later they figure out that many Trump supporters with millions of followers are posting from other countries. Surprise! That "feature" is now gone.

Too little too late

CSWEP strongly condemns Larry Summers’ behavior as revealed in the email correspondence with the late Jeffrey Epstein. While abuse of power in the economics profession is not new, rarely has the intent behind such abuse been so clearly stated.

Very exciting JMP on teacher value added — beyond test scores and into socio-emotional value added.

🤮 disgusting on so many levels

À really interesting short study — based on a survey in the US, the public supports Unis championing initiatives (environmental, DEI, free speech, …) beyond research & ed, but finds political engagement inappropriate. Women & liberals support DEI initiatives but men & conservatives do not.

« The era when American politics could make or break global climate co-operation is over. The world is no longer waiting for Washington. This time the global south is leading the way. » — a great piece by an architect of the Paris agreement @economist.com economist.com/by-invitatio...

People are crazy.

Researcher at OpenAI studied why LLMs hallucinate: it’s a fundamental feature of the approach, it’s not an engineering glitch that will be solved with more money or data.

Very important developments on regulating digital platforms operating in the EU. Glad to see Europe abiding by its principles on this one.

NEW: Something remarkable happened recently and hardly anyone noticed – GB electricity demand was 100% covered by clean power We took a look at the data and this has happened for a record 87 hours in 2025 to date, twice as often as ever before 🧵 www.carbonbrief.org/... 1/7

Very interesting read

Evidence from random roommate assignment and a gaming ban for minors in China once again show what I now believe incredibly strongly: smartphones and social media destroy civilization via @arpitrage.bsky.social

Thought about scientific consensus recently? We have a new DP @i4replication.bsky.social that probes into the famous replication debate between Acemoglu, Johnson & Robinson (AJR) and Albouy - and how experts assess this debate. We find that they disagree. 1/8 www.econstor.eu/bitstream/10...

Who's doing rigorous analysis on the effects of data centers on economic, health, energy, and climate outcomes? #econsky #energysky #climatesky

Important thread for people using causal inference methods in applied work

That is a very interesting short paper, and it reflect the mixed experience I’ve had and many academics around me have had with LLMs. Fully agree with @mjamurphy.bsky.social here ; perhaps we’re all better off sticking to open source that the web of Bernard-Lee was made to be

The best post I’ve seen on Bluesky in a very long time! Brilliant idea and brilliant accounts out there !

Fascinating piece on the very unique influence if the tech industry on the school system

Just spent two very inspiring days at the Summer School on Networks organized by my friend and coauthor @yveszenou.bsky.social at Monash Uni. Great lectures by Matt Jackson (Stanford), Sanjeev Goyal (Cambridge) and Yves — I learned so much! Thanks Yves!!! www.monash.edu/business/eve...

Just a reminder to check for your name in this list of books that OpenAI trained from. If your name is there, they probably owe you several thousand dollars. OpenAI cried that if everyone eligible author files, the company will go bankrupt, so I'm alerting every author I have ever spoken to.

Incredible!!!

academia is a v. strange mix of “we expect you to behave like an employee” (forms, webinars, insanely bad admin software, etc) but also “go fund your entire research operation yourself including paper towels for the sink in the lunchroom we don’t have the budget for that”. #academicsky

If you want to learn Bayesian data analysis, this guy wrote one of the best textbooks! 👉🏽👉🏽👉🏽

Excellent @newyorker.com piece citing lots of recent studies with very mixed evidence on the productivity gains of Gen AI — and a great complementing thread by @kmcelheran.bsky.social whose work is cited in the article. Thanks for adding many refs to studies Kristina!

Shout it from the rooftops: the real AI revolution will be later, less, spotty and uneven
