Come join me (and a bunch of much better economists) at the @PhilFedResearch! We are looking to hire two (seniorish) Macroeconomists in the research department. Pass the word, retweet, and/or apply if you are interested. econjobmarket.org/positions/…

On October 27 (18.00-19.30) Nobel laureate Joel Mokyr will deliver the 2026 Dondena Lecture, at Bocconi University (Milan). The event is free & all are welcome (physical attendance only), but registration is required (at the link: events.unibocconi.eu/index.p… ). @DondenaCentre 👇

Economics is the *only* scientific field in which the concentration of institutional affiliations of award-winning researchers (i.e., more winners at top universities) has increased over time.nber.org/papers/w35875

I am hiring a full-time predoctoral research fellow at Stanford @SIEPR to work on topics across economic history and the economics of AI.

A general principle: when you interact with AIs, you should know that you are interacting with AIs.
Tech like this that helps disguise AI makes us all worse off.
Working on camouflaging AI use should be viewed as unethical. This doesn't help anyone.
The whole point of building Tavus has been simple: talking to a machine should feel as natural as talking to a friend or coworker.
It’s hard to describe all the tiny nuances that make a conversation feel human. The little expressions. Moving around in your chair. Knowing when to speak and when to listen. The dance of it all.
Griffin is by far the closest anyone has come to a model that can capture those nuances. The first time I saw it being used, I had no idea I was watching our model rather than just a normal video call.
I’m so incredibly proud of this team and what they’ve built.

NEW: According to a bombshell report in the New York Times, Anthropic co-founder Chris Olah threatened to walk out of Pope Leo XIV’s AI encyclical launch in May because the pope rejected the idea that machines can be conscious.
Olah’s team then privately lobbied the pope’s advisers “to take the possibility of model consciousness seriously.” Pope Leo XIV held firm.
For months, Anthropic has wined and dined theologians and religious scholars under nondisclosure agreements, hoping they would bless the idea that Claude has moral standing. thelettersfromleo.com/p/nyt-…

If you think students can benefit from writing research papers, read this article! You can still assign papers!
Dartmouth profs are doing this very successfully. One approach is having students use Google Docs, where the version history proves human writing.
It works! 1/

I recently asked ChatGPT to improve the efficiency of some simulations from a few years ago. To my amazement, its code ran in a few seconds instead of 3 hours.
It turns out it went into the GitHub repository, downloaded my final results, and used it as a starting guess in the optimization.
I then tried running it on a new set of parameters. It’s been 15 hours.

L'École de Nancy c'est quelque chose.
Pendant plus de 50 ans, des fonctionnaires des Ponts et Chaussées ont classé leurs dossiers dans une maison de Nancy dessinée par des artistes jusqu'aux poignées de portes.
Les meubles, eux, avaient été dispersés. Nancy a mis un demi-siècle à récupérer la chambre.
C'est la villa Majorelle. Louis Majorelle, fabricant de meubles, la fait bâtir en 1901 et 1902 pour y vivre avec sa femme, Jeanne. Il la baptise villa Jika, d'après ses initiales à elle.
Un architecte parisien de 28 ans, Henri Sauvage, dessine la maison. Le verrier Jacques Gruber fait les vitraux. Majorelle dessine lui-même les meubles, les rampes et les ferronneries.
Tout est pensé ensemble, du plan de la maison au dernier tiroir, sur les mêmes lignes de plantes. C'est ça, l'Art nouveau.
En 1916, une bombe allemande abîme la villa. Majorelle meurt en 1926.
En 1931, sa famille vend la maison à l'administration des Ponts et Chaussées, qui y installe des bureaux. Le mobilier part aux quatre vents.
La chambre réapparaît dans une vente à Monaco, en 1981. La ville de Nancy et les musées de France l'achètent et la rapportent.
La ville rachète la maison en 2003. Après des années de restauration, elle rouvre au public en 2020.
Aujourd'hui, la chambre a retrouvé sa pièce. On peut entrer.

Everything in the accelerate plan is awesome but I think the biggest thing is that we are getting 15 minute regional rail confirmed! I cannot think of a more transformative single action that could be done by SEPTA with our existing infrastructure. Absolutely huge!

This is a game changer for suburbanite mindshare if we can make it happen. Enabling RR to run at frequencies close to PATCO unlocks a level of access to the city that's game changing. I cannot express how important it is we make this happen and convert riders to using it.

Reimagining Regional Rail is finally out!
The long term plan will turn a large part of SEPTA’s regional rail network into essentially a second metro system.

Are Big Tech acquisitions really "killer acquisitions"?
No, not on average.
We link 1,200 startup acquisitions to patent & workforce data. Acquired patents get cited more, and inventors who stay become more productive.
But serial acquisitions concentrate patent ownership.
