"Superstar labor econ team shows what we all should have expected: young workers learn more slowly when they work remote experienced workers "can do their job" remote but partly by ignoring mentoring. Not in this empirical design but I'd guess it applies to new tasks for all"

"I tell my PhD students to enjoy a good beach - more likely to not finish a PhD because you burned out than because you failed out. Still have to work hard of course but we had as many good ideas and discussions in grad school at Hopleaf on Friday night as we did in our offices"

"Second COVID. Visit China if you don't understand this. We interfered in a major way with an incredibly formative period of young people's lives. Imagine you had no normal school from 16-18 no prom no big game but just internet nonsense. Harms trust in the future. 3/5"

"No more credulous press than Canada in NYT. This year at U of T: new hires cannot buy house when they move here w/o giant "foreigner fee" PR cutoff is so high folks are worried about conversion X economists just at U of T had to leave temporarily b/c work permit got denied. 1/3"

"GPT XXX has amazing benchmarks (and is clearly great in many areas) but it joins Grok as the first "top" Western model with outright bad performance on some idiosyncratic tests I run (and on some "tricky" benchmark Qs I've made on contract for labs). 1/6"

"Third young people don't know anything. They learn about careers job ladders and get mentored. The huge boomer generation increases politician judge CEO average age by a decade. Then remote work made ladder feel more remote. In person SF is a huge part of why it works. 4/5"

"Here's one. XX photos from around globe. Most have no text/road marks/Geoguessr slop. No metadata. It's hard. XXX much worse than XXX and even with high thinking is at level of Gemini XXX Flash & worse than the final GPT XXX. On high think: 19th/32 models. Medium: 25th/32. 2/6"

"@Andrew_Semenza @GiveDirectly I want to help person X directly. Imagine cash is 2x as valuable in consumption because Of Hayek effects than in kind. But effective tax rate on cash is 60%. Depending on how I weight the people who get the second degree transfers I can be worse off"

"There are some legitimately good jokes here. We are still underrating AI creativity (which to be clear we are not really even trying to maximize). The Gary Marcus one at the bottom in particular and "nostalgic-coder" for those who write code without an AI"

"With Anthropic and Google models + OpenAI models until very recently general benchmark trends and these "internal" ones basically follow each other. But with XXX and all Grok models (grok-4.1-fast is 31st/32) performance here is terrible. I have some ideas on why. 3/6"

"@spencerreiss More than happy to let people who want to live on a big lot of land do so But land built like in the pictures is objectively worth tons more per acre. I think people should be allowed to build Dubrovnik and Aix and Kyoto and Venice. You don't have to live there of course"

"(Intuition: I can price discriminate you can't. Best response give as many of your customers as I can one cent of surplus to buy from me instead. In eqlm this causes the fixed price vendor to have to lower prices pulling in residual demand curve the price discriminator faces)"

"Noah notes this amazing fact but the crazier one re: Pakistan is that Bangladesh and India have exactly the same trend. And as noted India has the real GDP PPP p.c. that China had when I was an embassy intern there XX years ago + better demographic dividend. I'm very bullish"

"AI & Robotics are a complement and a substitute for labor. There isn't a fixed set of jobs. Scarce factors get rents - since AI/robots won't be scarce the rents won't go to them. This way of understanding AI + Labor (via Bernie Sanders in the Guardian) common but totally wrong"

"@itaisher I think we are pretty clearly the field that leads in casual machine learning experimental design and AI-relevant theory. Athey is giving keynotes at NeurIPS. All the labs are hiring economists to work on AI policy. Growth theory language is somehow known by many in SF"

"Subtlety - in differentiated product markets with competition if firms can price discriminate usually lowers firm profits. This can be true even if only one firm can price discriminate (this is a result of mine from grad school I never published; many I should dig it out)"

"@ryancbriggs Nice. I give friends "index card advice": 1) pay off high interest debt 2) spend less than you make 3) X months of $ then VTI in tax advantaged way 4) track annual spend to avoid hedonic treadmill 5) buy fewer positional goods more "you & Bill Gates get the same thing" goods"

"Re: @emollick this is bad UX from OpenAI. This output so different from anything I ever see from GPT either on website or API that I'm sure it's coming from some combo of Instant + some strange "personality" setting. When you mix low and high quality AI people get confused"

"@alz_zyd_ @ashdgandhi The why is obvious in math though. Tomorrow we show a singularity in Navier- Stokes sense. The whole reason we will care is because we think the explanation of how we figured out will help solve practical fluid dynamics problems. Yes/No is rarely valuable"

"I like this benchmark b/c it has AI describe why before giving location. Sometimes clear (as in earlier Claude models) that vision model is problem- it's not seeing details. See here: GPT-5.2-high can't "see" polo mallet or "King of Games Game of Kings" on wall but XXX did 4/6"
