Two orders of magnitude cost reduction in GPT-3.5 class model cost in a just a year. That is far above Moore's Law pace, or almost any cost improvement rate for any production technology that I can think of.

Ello, gov‘nor! 🎩

A highly important open question about AIs has been whether they can actually discover new things. Today, a new Nature paper has shown that LLMs can! A model "discovered new solutions for the cap set problem, a longstanding open problem in mathematics" nature.com/articles/s4158…

Will this lead society towards anti-digital realism or towards reflecting anti-realist subjectivity of perception?

There is an ongoing discussion involving Harvard and MIT, two institutions where I spent plenty of time during the past 20 years. I first came to Harvard as a visiting PhD student in 2005, then joined the Kennedy School as a postdoc in 2008, and in 2010 I joined the MIT faculty,

Early adoption of artificial intelligence (#AI) gives a huge advantage to pioneering places. Firms in early-AI adopting #regions benefit from this. In the #Netherlands, AI concentrates in big cities and peripheral regions are not catching up, says Harm-Jan Rouwendal at #GeoInno2024

The next Geography of Innovation Conference will be in Budapest in 2026. We are thrilled to organize the event with Corvinus University of Budapest and HUN-REN KRTK. The community of ANETI Lab and Center for Collective Learning is looking forward to welcome you in this beautiful city! #geoinno2026

We are back!! On 16-17 May we will host the second edition of the "AI beyond the hype" workshop. This time at the campus of ESSEC Business School in Paris! Mark your calendars and submit your best abstracts before Feb. 29. We hope to see you soon in Paris! Cristina Alaimo and @lauren_wbg

Carless cities ==> life

Meine Theorie ist ja, dass Weselsky mit der DB gemeinsame Sache macht, damit unter dem Deckmantel des Streiks Weichen unbemerkt repariert werden können.

Interesting paper on a novel "AI exposure" that explains the slower roll-out of AI from a cost perspective. One of the takeaways for me is that automation is not necessarily economically attractive - perhaps more efforts could be devoted to use AI to complement workers.

Tell me you work in econ without telling me you work in econ.

Wie viel zusätzlichen Umsatz Fastfood Ketten in und um Bahnhöfen wohl durch Verspätungen der Deutschen Bahn machen? #positiveexternalities

Jetzt schon meine Entdeckung des Jahres: Osnabrück Hbf als Umstiegsbahnhof. Ansehnlich, übersichtlich, sauber, belästigungsfrei, gut versorgt. Und: Zugänge zu Gleisen auf zwei Ebenen für Umsteiger gut verbunden. Top Bahnhof für Reisende nach NL!

Humbled to share that my dissertation was awarded with the Südwestmetall prize in support of junior researchers making societal impact. Thank you. 🙏 This prize means a lot to me because it shows that our research is acknowledged beyond purely academic circles.

Eleven years ago, I quit an abusive academic relationship with my former co-author Ricardo Hausmann, presently a Professor of Practice at the Harvard Kennedy School. This abuse has now returned in a new act of plagiarism. Today, I am pushing back. A few months ago, I learned

Retracing (rewriting?) economic history with the help of machine learning. ⬇️

How can we separate signal from noise when working with web data to understand socio-economic change? We discussed all of this at our 3rd annual 🧙‍♂️ ISTARI.AI 🧙🏾 research workshop with more than 20 of our international researcher partners. 🧙‍♂️🧙
