How do corrective taxes work when firms can reformulate products to avoid them? My #JMP studies the UK’s Soft Drinks Industry Levy: a tax with a multi-tier structure in which more sugary products face higher tax rates. #econtwitter 📄 Paper Link: jiboncom.github.io/boncompte…

"ANOTHER LULA WILL NOT BE BORN" For two decades, Brazil’s president has showed the world’s progressives how to build and wield power. But his winning coalition is about to unravel, forcing harder lessons for the global left. @EvaHartog in @POLITICOMag: politico.com/news/magazine/2…

Parametric brick is beautiful (I used it on my own facade!) and w/ partial roboticization of bricklaying can be very cheap. Good brick and mortar materials cost, even architectural, on a 20x40 front facade is like $7k. The history of new design is materials & labor being cheaper!

Foursquare acertó: el móvil iba a saber dónde estábamos y el sitio importaba tanto como la foto. Todo eso se cumplió. Pero dentro de Instagram / Google Maps / WhatsApp. Nadie abre una app para decir “estoy aquí” si la que ya tiene abierta lo hace sola. Llegó a facturar +$100 millones al año y sus accionistas se quedan con 0. Cuando la deuda pesa más que el negocio da igual lo que factures.
FourSquare fue una de las startups más seguidas de 2009/2010/2011. Ha terminado vendida por $0. teendrama.substack.com/p/som…

To justify today’s data center buildout, AI would need to bring in about $3.5 trillion a year by 2032, per a new Brookings paper. That’s 8.8% of U.S. GDP, nearly as much as Americans spend on food (9.1%), and far more than on energy (5.1%).

Best take so far
100% this 👇. The irony of running academic work through Pangram and getting outraged by a high percentage is that you’re outsourcing your own judgment to AI. Your assessment is itself 100% AI-generated. We should use our own brains both to produce academic work (with AI assistance or not, your call) and to assess it. If you need Pangram to tell you that something is AI slop, that tells you everything you need to know about where we’re heading.

Se les advirtió hasta el cansancio. El famoso "retiro de rentas vitalicias" (el puro nombre ya es disparatado) fue la parte más delicada de la borrachera.

"Una reducción de peajes acompañada de una extensión del plazo de la concesión posterga la ampliación y mejora de la carretera, pues estas ocurren cuando se relicita la obra y se inicia una nueva concesión. Y esas obras se volverán aún más urgentes, porque los menores peajes aumentarán la demanda", Eduardo Engel, académico FEN, en cartas de El Mercurio.

Wow, ahora ya parece una pelicula de acción
We discovered a sophisticated recording device that was hidden inside one of our offices. We used our models to understand the device and where it had come from, identifying that a specific employee had planted it a few days earlier. We referred the matter to the FBI, and we’re grateful to the agents and prosecutors who moved quickly to make an arrest. The FBI’s investigation is ongoing and we will continue to support their work. At this time, we have no indications of this individual inappropriately accessing or exfiltrating model weights, source code, or customer data. The employee was terminated. We take protecting our technology, data, and people seriously, and as a matter of national importance. Our security program is designed to protect against a wide range of threat actors, from insider risks to cybercriminals to nation states, and this case is an example of how AI can help address these sophisticated security threats.
