1/ Das #Klimaschutzprogramm 2026 ist da! #KSP2026 ▶️ Hier gibt's die PM: www.bundesumweltministerium.de/pressemittei... ▶️ Hier das Programm selbst, ein Hintergrundpapier, und eine Wirkungsabschätzung: www.bundesumweltministerium.de/download/kli... 🔽 Und unten im Thread eine erste Einschätzung von mir

🇩🇪 discusses about part-time work and about its joint taxation of couples. Good! The government's disdain of part time work makes many people angry. But there is a behavioral econ truth to it: people underestimate how part time work obstructs their careers and wages. See our paper 👇🏼 1/4

I thought it was the boat at first 😄

Is falling on your head as an infant some kind of evolutionary strategy to unlock hidden brain capacities, or something?

Stark contrast to the gerontocracy that is the US Congress. already visible in the campaign posters in the last four weeks, but now it’s clear “the average age in the new Folketing is 43.9. The youngest ever,” especially “young women are storming the parliament” (in Danish) www.dr.dk/nyheder/poli...

What about instead of imposing impossible standards and arbitrary personal rules, we allow for imperfection but quantify the effects of exclusion restriction violations with rigorous sensitivity analyses?

Der 🇩🇪 - 🇫🇷 Rat der Wirtschaftsexperten spricht sich ausdrücklich für die Beibehaltung und Stärkung des europäischen Handels von Emissionszertifikaten #ETS aus. Die ständigen Angriffe darauf müssen aufhören. Mitentscheidend für den Erfolg von Klimapolitik ist ihre Stabilität.

I'm a technology and innovation researcher, but somehow I can't seem to buy into the hype. Do I have the wrong profession or is it a consequence of my training?

Auf Twitter twittert es weiter...

False claims in a widely-cited paper. No corrections. No consequences. Welcome to the Business School. statmodeling.stat.columbia.edu/2026/03/24/f...

it reminds me of this classic Derrida anecdote:

Happy "large enough n" day

I'm happy to share that I’ve been appointed Professor of Empirical Economics & Data Science at the Technical University of Munich (TUM), Campus Heilbronn. After 9 years abroad, it's great to be back in DE. Looking forward to building a team and working on #CausalAI in this fast-growing ecosystem.

Me and my data

Another emigration wave from the cesspool or bots?

This is just a funny meme, so no dig at Kai. But we need to teach students more than that. If correlation isn't causation, then what are the conditions under which we can make causal claims (and that's not just randomization)? Science doesn't benefit from causal nihilism.

The one thing that my students remember from stats

Dropbox Reallocated $25M of Their Marketing Budget After a Causal Study. In this week's issue of Causal Python Weekly: - Alberto D. Horner reviews a new End-to-End Estimation for Counterfactual Fairness by Yuchen Ma et al. 1/ #CausalSky #EconSky #EpiSky #StatSky #MLSky

Embracing Defeat is *fantastic* Drop what you are doing and go read it now.

Who else would question Finland’s No. 1 happiness ranking if not the Swedes?

The "tough nurse" was a perfectly fine metaphor to illustrate the issue of noncompliance in RCTs.

At the business school, fields are either influenced methodically by economics, sociology or psychology. Guess which ones have the fanciest empirics.

Uff... 😣

Yes. Then if you push on this the claim becomes “okay it may not cause but it’s still useful because it predicts”. But then it’s like if predictive accuracy was your goal the design and analysis should be different e.g., CV + more predictors. I’ve been fully Westfall & Yarkoni-pilled on this point.

We should replace 50% of specialist disciplines with mandatory stats and causal inference training.

"Impact" is really the latest fad of university admins, isn't it?

Another week in which I ask myself who are the compliers in a complier average causal effect and why are they our target population

Discovery versus creation of entrepreneurial opportunities

Japanese PM Sanae Takaichi's reaction as Trump says "Who knows better about surprise than Japan? Why didn't you tell me about Pearl Habour?" Undoubtedly the worst American diplomatic gaffe in post-war US-Japan history.

Remarkable story from Denmark's nat'l broadcaster. "When Danish soldiers were flown to Greenland in January...they brought explosives so they could destroy, among other things, the runways in Nuuk & Kangerlussuaq [to] prevent US mil aircraft from landing" www.dr.dk/nyheder/indl...

There was a time when this guy was actually a reasonably serious commentator on economic policy. Like Nate Silver, he decided to take the mask off, & it's just incredibly ugly now.

Man kann ja den typisch deutschen Professor:innen-Duktus amüsant finden. Aber in Skandinavien, wo man von der Gesellschaft als besserer Gymnasiallehrer betrachtet wird und die Studierenden einen mit "Ey yo" ansprechen, ist es auch nicht unbedingt immer besser.

Befristete E13 Stelle (Nachfolge von Georg Henning)

Forthcoming in AEJ: Applied Economics “University as a Melting Pot: Long-term Effects of Internationalization” Debates on international students often focus on capacity, funding, or competition. My paper shows the main effects on natives are not academic or economic, but social.

I have noticed this too (though not amongst my followers - you guys seem mostly cool). We need to speak out to stop this, or else Bluesky will become the same kind of racist cesspool as X, but with different politics.

Adilettendichte am Frühstücksbuffet auch überdurchschnittlich hoch

This deserves more attention. Moretti regresses patents-per-coauthor (Y/X) on cluster size (S), controlling for number of coauthors (X). But there are mechanical correlations between Y/X and X (negative) and between S and X (positive). 1/

I just noticed now that the LaTeX Beamer package makes it even harder for Germans to distinguish between the false friends "beamer" and "projector." 😅

Marc's giving students that retro experience. 😃 I once had to give a class on the do-calculus without slides because the projector in the room was broken. I remember it was the most memorable class of the entire course for students and several of them mentioned it positively in the evaluation.

Damn, should've worn my skinny jeans to this family hotel
