What would taxing unrealized capital gains — or wealth — do to entrepreneurship? If illiquid founders must sell shares to pay such taxes, how does this extra dilution affect incentives? 🧵 on my new paper with Eduardo Azevedo, @KentOnMoney & Min Yang 1/10

🚨 2025 Nobel Prize in Economics goes to Mokyr, Aghion and Howitt 🚨 "for having explained innovation-driven economic growht" The best prize in years!

Philippe is a brilliant researcher and economist but he is also a wonderful advisor. He is eager to work with students and to teach them, and I have immensely benefited from him.

This is a wonderful prize. Philippe has truly been the centerpiece of research in economic growth for the last 30 years. His communicative energy has pushed the field forward and his contribution is immense. I am extremely happy to see my mentor and co-author recognized this way!

I am delighted to share that Nobel laureates Esther Duflo and Abhijit Banerjee will join our Department of Economics @econ_uzh at the University of Zurich on July 1, 2026, as Lemann Foundation Professors of Economics. 🧵 1/7

Puisque c'est dans l'actualité, je me permets de ressortir ce papier publié en 2019 avec plusieurs (supers) coauteurs qui montre un lien causal entre ⬆️ des inégalités aux US et l'innovation Nous estimions que 1/4 de la ⬆️ de la part du top 1% peut être expliqué par ce canal

Unquestionably the most dangerous and corrupt attack on the independence of US economic data in American history. Trump is firing the head of the BLS, an longtime civil servant confirmed 86-8 by the Senate, simply because the job numbers came in below his expectations today

Il n’y a pas de contradiction: tout le monde est matraqué fiscalement et subventionné en même temps. La tuyauterie est totalement opaque, le système hyper compliqué, qu’il crée la suspicion légitime que le premier qui renoncera à son bout de lard sera le dindon de la farce.

The figures here tell the story better than the abstract

C’est quand même vraiment complètement fou.

Big congratulations to my great colleague @YanagizawaD for sharing this prestigious award! We're proud this is the second time the award goes to @econ_uzh, after Fabrizio Zilibotti won it in 2009.

Je ne reviendrai pas à RTL. C’est ma décision. Voici pourquoi. Il y a quinze jours, mes propos sur la colonisation algérienne ont créé le débat. La direction de la radio m’a dit avoir enregistré de nombreuses protestations de la part des auditeurs. Pour faire droit à l’émotion

Labour market policies influence firms' innovation dynamics, as a UZH study shows. Higher minimum wages encourage automation, while rising wages for highly skilled workers slow it down: https://t.co/d70Tks1mYl @econ_uzh @davidhem

Europe made a colossal mistake: They banned genetically modified organisms (GMOs) while the rest of the world embraced them. Now we rely on imports, pay more for food, and miss out on sustainable agriculture. Here’s the story of Europe’s GMO debacle 🧵:
