I'll say it once more: German cuisine is severely underrated internationally, especially by Anglo-Saxons

Unfortunately, many top academics in the U.S. appear remarkably corruptible. As opportunistic as the DEI agenda of the 2010s often felt, the current moment shows how quickly positions adjust to a new reality.

"Wer die Batterie beherrscht, beherrscht das Auto", sagt der Technikvorstand von Volkswagen. Der Konzern versucht gerade die Batteriezellenproduktion Made in Germany zum Laufen zu bringen, was Chinas Hilfe nicht mehr geht. Merz Aussage zum "hocheffizienten Verbrenner" wirken dadurch noch absurder.

This paper describes the idea of a "Causal AI Scientist" In my recent interview with @zhijingjin.bsky.social we discussed various ways in which LLMs can be useful in the context of causal analysis. Causal AI Scientist (CAIS) is one of them. 1/ #CausalSky #MLSky #StatSky #EconSky

Der US-Präsident erklärt das bedeutendste Medium des Landes zum „Volksfeind“ und verlangt, dass es „gestoppt“ wird. Aber Europa hat ein Problem mit Meinungsfreiheit… 🤯🤯🤯

Presidents of German economic research institutes be like: 👀

Yeah bsky is no longer a place you can be a quant social scientist. It's done for that.

Sorry, man. I keep wanting old school AI/ML Twitter to manifest here (or at least somewhere not Xitter), and it’s just not gonna. *sigh*

That Bluesky is so AI-hostile really is unfortunate. Not gonna go back to the cesspool, but this gives people an excuse to stay on there longer.

Nothing to see here…just the US president threatening European sovereignty

A new major logistics hub for Ukraine will open in Romania by the end of January 2026, becoming the second-largest in Europe after Rzeszów. It will allow NATO to double the flow of military aid to Ukraine, including through the PURL mechanism, where the U.S. supplies arms and Europe covers the cost.

DAGs, people!!!

The uncertainty created by these periodic nationalist backlashes (also in Denmark, for example) unfortunately puts brakes on the much-needed internationalization of European science and academia.

Canada was their top customer! And thanks to President Deals, we stopped buying bourbon months ago. Billions and billions of dollars in sales, gone www.kentucky.com/news/busines...

The Abundance movement often points to environmental groups as the obstacles to building. But who actually files the lawsuits blocking projects? It’s not environmental groups. It’s been lawyered-up HOAs protecting property values all along. Regulation by litigation is the problem.

Some days ago a student struggling with her master’s thesis e-mailed me, asking me about partial least squares structural equation modeling. I told her I can only tell her not to do that, and then she sent more details.>

It's that time of the year again 🎄📽️

This smells distinctly like collider bias and/or selection bias and/or regression to the mean... You simply can't select teen prodigies, and world class athletes rom databases, and go run regressions without serious consideration of the selection process!

If Mokyr is right, the U.K.'s position as the epicenter of the modern degrowth movement may be a causal factor behind its economic lack of dynamism.

"And so we have a bad equilibrium. Instead of stagnation causing a desire for and interest in pro-growth policies, it actually strengthens the pressures on politicians to wallow in that stagnation." Good points!

Journal article: “the data are available on request” The data:

This is one of the best papers that I've read this year! It demonstrates the power of bringing rigorous modern empirical methods to bear on the intuitions developed by previous generations of social scientists -- in this case Bourdieu. It also helps us soumitrashukla.github.io/making_the_e...

There's a powerful illustration here regarding "influencers" vs. "experts".

Human psychology is not made for zero or degrowth

💥 “It’s not clear who attacked whom,” Hungarian PM Viktor Orbán said today at a presser on the Russia–Ukraine war, after an EU summit where he opposed any financial help for Ukraine. Orbán is now clearly escalating his rhetoric, for the first time openly questioning that Russia started the war.

The intuition for the new measures is simple. A publication is innovative if it is more similar to the future of its field than to the past of its field. If a title anticipates where the field is going, it is a first mover. It is innovative.

New working paper 🚨🚨🚨 What was the origin of modern economic growth? Joel Mokyr had a Nobel winning answer - growth took off when science and technology began to reinforce each other But can we test this quantitatively? This paper does so – read more ⬇️ 🧵

"I once applied for a professorship in Germany and only heard back 2.5 years later. Here is how this radicalized me against the woke zeitgeist."

One additional point on politics: Without the very strong push especially from Berlin for the use of the Russian assets, Orbán would most likely not have agreed to this lesser-evil solution from his (and Putin‘s) perspective. The threat was real, and he caved.

Politico’s European coverage verging on self parody.

A few quick thoughts about this morning's decision. Don't believe the spin from various Russians & others: it's a big deal. The EU has now unambiguously demonstrated that it is able and willing to provide the external financial support Ukraine needs, for as long and as much as it takes. (1/N)

I got quoted together with my colleagues at Vilnius University in the Lithuanian newspaper IQ. iq.lt/mob/komentar...

So what the hell just happened? Two things: Ukraine will get 90 billion euros. And Orbán did not veto that even though he could have. How so? Short thread:

A quick explanation of how this borrowing to assist Ukraine will work. "Enhanced cooperation" means EU law is being used, but some Member States opt out. The process has been applied a few times before, but never before re the EU budget. 1/

The 2002 steel tariffs in the US (under president George W. Bush) created persistent negative employment effects in manufacturing industries that rely on steel as an input - despite being removed after 18 months. New evidence in "American Economic Journal: Economic Policy":

Just got a paper to review where the authors labeled lasso regression as interpretable AI in the paper's title. Holy crap. #StatsSky #Statistics

"It must not be overlooked that junior researchers DO NOT TRUST US. We, the directors, are a big part of the problem. We made this system, we remake it every year, and we benefit from it. What can we do to credibly signal our commitment to reform a corrupt research culture?"
