Remember to be wary, as today is the only day of the year that incorrect or misleading information is posted on the internet.

This is either brilliant or scary: Anthropic accidentally leaked the TS source code of Claude Code (which is closed source). Repos sharing the source are taken down with DMCA. BUT this repo rewrote the code using Python, and so it violates no copyright & cannot be taken down!

Was mir gerade auffällt: Die vielen, großen Demonstrationen zum Thema sexualisierte Gewalt werden als politische Demonstrationen kaum ernst genommen. Und das, obwohl es bei vielen dieser Demonstrationen ganz klar nicht nur um politische Forderungen geht, sondern auch um gesellschaftlichen Wandel 1/2

It's also a very narrow and unhelpful view of innovation. Changing processes can be a very useful pathway to productivity growth, even though it's not as glamorous as "inventing the internet"

This by Rheinmetall CEO is precisely the arrogance that will come to haunt 🇩🇪. It was arrogance vis-à-vis Chinese competitors that helped bring German carmakers in the ditch they are in. And it‘s this type of arrogance vis-à-vis lessons learned by Ukrainians that will cost us.

On Tuesday, the 3rd edition of the @diw.de - @oecd-ocde.bsky.social Industrial Strategy Dialogue took place at DIW Berlin. This time, the panel discussed how Germany and Europe can more widely incorporate artificial intelligence into businesses. (1/4)

Ein ständiges Zurückrudern bei Zielen & Instrumenten ist äußerst schädlich. Ohne Planungssicherheit über die künftige Klimapolitik – wenn also stets mit einer Abschwächung der EU-Ambitionen zu rechnen ist – tätigen Unternehmen die notwendigen Investitionen in CO₂-arme Technologien nicht.

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.

In our new research paper (joint work with Leander Andres, Gordon B. Dahl, Helmut Rainer, and Simone Schueller), we show that birthright citizenship substantially declines youth crime of children born to migrant families. Here are more details of the study design, data, results, and mechanisms:

Every responsible decision maker in politics, industry etc. should read this. Or better yet the original WMO report it’s about (linked in the article). And then think very seriously: What am I doing to stop this? Is it enough? How do I want to be remembered? www.theguardian.com/environment/...

🧵A thread on "AI one-shot papers". This has not been a focus on Bluesky, but on Twitter/X and LinkedIn, there has been a large discussion of the ability to "one-shot" policy evaluation, which David Yanagizawa-Drott has been pursuing in an interesting way: ape.socialcatalystlab.org

Tired of fragmented academic profiles? I built a tool to fix it: acadmc.com. A lightweight profile page that brings together your Scholar metrics, ORCID, and preprints in one place. Built by an academic, for academics. Your research graph in one place. #AcademicBluesky #Science #OpenTools

Digital platforms shape markets and public debate at a scale that would have been hard to imagine a decade ago. At the same time, independent researchers face obstacles when trying to study them. As a result, much of the digital economy remains difficult to examine from the outside.

Ohnehin zählt Deutschland im EU-Vergleich zu den teuersten Kraftstoffmärkten, nun fielen auch die jüngsten Preisanstiege hierzulande besonders hoch aus. Die Gründe dafür beleuchtet DIW-Ökonom @tomasoduso.bsky.social in seinem Gastbeitrag für @zeitonline.bsky.social: diw.de/de/diw_01.c....

Takeshi Amemiya, my colleague and friend for many decades, has died at age 90. He made fundamental contributions to econometrics, having, as an empirical scholar, some gripes with the available toolkit. In retirement, he taught a course on the Economics of Ancient Greece. /1

Germany is just great at own goals. This here is an impressive bicycle kick into its own net. www.handelsblatt.com/politik/konj...

Just to say the policymakers would be wise to always consider the scholarly level of their advisors. Among colleagues, Ulrike Malmendier is known to be a heavy hitter like very few on this planet.

Disappointing decision www.handelsblatt.com/politik/konj...

Um es klar zu sagen: Hier macht die Bundesregierung einen schweren Fehler. #Malmendier

Large-scale online deanonymization with LLMs shows how easily pseudonymous users can now be re-identified from unstructured text alone. When discussing our EJMR paper at NBER SI 2023 Catherine Tucker argued that rising compute would soon erode online anonymity. The future may already be here.

Nochmal zum Mitschreiben: Russische Angriffe auf die Ukraine zerstören Teile einer Pipeline, über die russisches Öl nach Ungarn und in die Slowakei geliefert wird. 1

The first and last lesson of history is that it has always been a garbage time to be alive. Nostalgia is a fine thing to indulge by the fire with friends, but institutionalized nostalgia for a bygone era is a sign of arrested development.

We won our tariff case!! Yay!! A 6-3 decision. Much more to come later. Here is the link to the decision: www.supremecourt.gov/opinions/25p...

When I orginally said this in some interview, I was not intending to say anything deep (and did not know they would put this on a kitchen magnet). I do think it is interesting to reflect on the fact that in some fields there are well-defined questions that the field agrees on are important. (1/3)

Folks, some news. No, not that kind of news – what do you think this is, LinkedIn? It's this: 1. The applied causal graphs workshop deadline is 28th Feb. so get your abstracts in and hang out with us in Potsdam this May. Form and description is below 2. @dagophile.bsky.social is giving a keynote 🥳

Robynn Cox and I have a new paper! It's about the history of predictive algorithms in criminal justice, back in the 1920s-1950s. This paper is the result of five years of research and we're so happy to see it out. 🧵 1/

2/12 There is a reason why Putin, Musk, Trump, Vance, Thiel, and Xi all spend fortunes to attack Brussels. They do not hate the EU because it fails. They hate it because of its potential. Our unity is their nightmare

📢 „Das wäre ein Durchbruch“ 🗣 Interview zum geplanten Forschungsdatengesetz mit unserer Vorsitzenden Prof. Dr. Kerstin Schneider

core part of the ostensible economic justification for mass deportation was that Americans would rush in to take all the jobs immigrants left, but now unemployment rates for native born Americans are rising and the admin is sending people out to do damage control

Sehr wichtige Stellungnahme des @vfsecon.bsky.social zum #FDG Entwurf des #BMFTR: www.socialpolitik.de/de/referente... Verdeutlicht, wieviel auch nach evtl. Beschluss noch zu tun bleibt und weitere Gesetzesänderungen in der nahen Zukunft wichtig sein werden.

Die Beantwortung dieser und vieler weiterer zentraler Fragen hängt entscheidend von der Verfügbarkeit und der Verknüpfung hochwertiger Forschungsdaten ab – in der Sozialversicherung und im Gesundheitswesen ist dies mitunter sogar lebenswichtig.

▶️ Wie wirksam ist Strafverfolgung? ▶️ Welche arbeitsmarktpolitischen Maßnahmen schützen tatsächlich vor Schwarzarbeit? ▶️ Und ist bessere Bildung ein Schlüssel zur Prävention von Gewalt in der Familie?

Little to add to Trump's Endangerment Finding move that hasn't already been said, but here's the key bit: Framing matters. This isn't "economics" vs climate, or some kind of noble "cost-cutting" crusade. It's a handout to narrow fossil interests, counter to economic forces.

No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition. Which just makes me want to share it again: www.nature.com/articles/d41...
