Fui ler o paper do NBER que tá sacudindo Singapura. Pesquisadores de Stanford e Columbia usaram IA pra varrer TODAS as transações imobiliárias do país entre 1995 e 2019 e cruzaram com o cadastro de 141 mil servidores públicos. Funcionários compravam imóveis perto de futuras estações de metrô 1-2 anos ANTES do anúncio oficial. 60% acima da taxa normal. Não pagavam mais caro na compra, mas revendiam com retorno de 12% ao ano. Os parentes faziam a mesma coisa. S$270 milhões no total. Pra descartar que fossem só mais espertos, compararam com corretores de imóveis e diretores de empresa. Nenhum dos dois mostrou o mesmo padrão. Rodaram 1.000 simulações aleatórias e o efeito real ficou totalmente fora da distribuição. Quem mais operava? Gerentes médios do planejamento de transporte. Cargo suficiente pra saber, baixo o bastante pra ninguém olhar. Em 2012, Singapura apertou a fiscalização com novas leis e punição de casos de alto escalão. O padrão sumiu, dos funcionários e dos parentes. Singapura é top 5 em transparência no mundo. Norma social sozinha não segurou. fonte: NBER WP 35756

But is he an honesty researcher?
Absolutely beyond parody. Dartmouth’s provost has been turning in 70-100-percent AI-written work (in academic journals, newspapers, and even in email correspondence!) since LLMs came out, the student paper reports. He even used AI to write an op-ed about how universities are dealing with AI cheating.

Yesterday, I led a workshop on AI strategy to the leadership of Southern Denmark University (SDU), a public university with over 25k students. SDU wanted my help to think about how to integrate AI into their overall strategy. Here's what I told them: 1. Based on a survey I conducted, few of the leadership had used AI past Copilot. I emphasized how disastrous top-down AI strategy decisions can be from leadership with little understanding of AI, and pointed out that in the economics profession, most "AI diffusion" was bottom-up. Typical pattern - a prominent economist (e.g. @cblatts, @pedrohcgs, @causalinf ) tries AI, has a great experience, writes about it, and then others - through their trust in them, decide to try it themselves. IMO most university's strategies should be focused on facilitating bottom-up diffusion. 2. What does facilitating bottom-up diffusion concretely mean? Here are some thoughts: > University faculty NEED to be able to make their own decisions with their own research funds on Claude/ChatGPT subscriptions. It's critical to chip away at any obstacles which prevent this from being frictionless. > Don't bother spending one penny on a university wide Gemini or Copilot subscription. It wastes everyone's time by misdirecting attention at vastly inferior products ("why do you want Codex? You already have OpenAI models through Copilot 🤮) > It likely makes sense to give a university's most AI-pilled researchers an option to replace some service responsibilities with some low effort "AI office hours" or similar mechanism to facilitate the spread of their knowledge throughout the university. 3. There are no risk-free decisions. Many universities' AI policies get stalled at floundering about data security risks and questionably relevant regulations (eg GDPR), without considering the risk of *not* acting to prepare your students and faculty. I asked the faculty to work through a short "AI 2031"-like scenario of what bad outcomes look like for their department (e.g. difficulty attracting researchers, bad labor market outcomes for graduates unsmoothed by American AI tech riches) from not acting. FWIW, I'm sympathetic to the difficulty of deciphering through personal/team/enterprise plans on the privacy implications of different frontier model subscriptions. It's far from transparent - I plan to make some sort of guide for this. 4. I gave a few final practical recommendations: > For senior faculty/administrators no longer in the weeds with research, I recommend checking the option in Codex/CC to not train on your data, and hook up your tool to your email + AI notetaker. So much of the value I get from these tools comes just from doing this. > It's important to do cost/benefit calculations with your political acts. Okay, you don't want to use ChatGPT/X b/c of Altman/Musk, but you're losing a lot of your own potential efficacy by cutting off those options. I pointed out in particular the importance of X for both keeping up to date and understanding the spread of AI in academia, and pointed the faculty at my list of economists to follow in this space.

This is pretty smart.
🚨 OBAMA ON AI: "If we are thinking about AI just in terms of how do we cure cancer or get better energy, you can do that without having agentic AI and having it just roaming free in the internet. The reason you are doing that is because you have to market a product that people will pay money for. That’s a misalignment between what our society needs and the commercial imperatives that these companies are facing, not because necessarily they’re trying to do bad things, but because they’ve got to justify these valuations. So, that’s one more reason why it is really important for us to have a competent government and a serious bipartisan conversation around this issue, and we have to do it fast. And I would encourage voters to pay attention to this. If somebody does not have a serious plan for how to deal with this, then they’re not meeting the moment, and you should probably look for somebody else."

Cannot overstate how perfectly this captures what is missing from so much AI discourse. Before declaring imminent utopia or dystopia, read this. It is an exceptionally clear account of the messy, constrained engineering reality behind turning algorithms into systems that actually work in the real world.

Worth reading
I must be among an extremely small group of people (n=1?) that have both 1) trained a frontier LLM and 2) designed and synthesized custom viruses in a lab with my own two hands. And I think that the takes on AI killing us all by creating dangerous viruses is total bogus.

We need to do this for Lyme disease.
Rabies kills ~59,000 people a year globally. At that rate, the United States should lose 2,500 people a year to rabies. But the real number is fewer than 10, partly because we've spent 30 years dropping fish-flavored ravioli out of helicopters over the Appalachians. Each one contains a rabies vaccine inside a fishmeal-coated block. Raccoons, foxes, coyotes and skunks find them by smell, bite through, and enjoy the treat. Four to six weeks later, they carry rabies antibodies. Enough of them in one area and the virus runs out of animals to move through. USDA Wildlife Services has been doing this this line since 1995. It runs roughly from Maine down through Alabama, and its job is to stop raccoon-variant rabies from crossing into the central US, where it has never established. A single course of post-exposure shots runs into the thousands of dollars, and every rabid raccoon in a suburb produces a cluster of them: the kid who got scratched, the dog that tangled with it, etc. US rabies prevention costs between $245 and $510 million a year and avoids over a billion in medical spending. Long Island is probably our best case study for this program. A $2.6 million baiting program eliminated raccoon rabies from the zone, and paid for itself in eight years on avoided shots and testing alone. The biggest question I hear about this is: what happens if my dog finds one? And the answer: nothing bad. This vaccine has been safety-tested in over 60 species at varying doses with no adverse reactions observed, regardless of how much was given. About 250 million doses have been distributed worldwide since 1987 with no documented deaths in wildlife or domestic animals. The most severe adverse reaction observed was upset stomach.

I'm not a fan of multiple comparisons corrections (e.g., Bonferroni, Benjamini-Hochberg, etc.). Just preregister everything and report all results (or else do some kind of multiverse analysis or specification curve), and let the reader decide. One of the biggest issues for me is the following paradox. Say I run an RCT testing a drug as to LDL levels, and I'm trying to decide what outcomes to measure: reduction in LDL over 1 year, cardiac outcomes over 3 years, or mortality over 5 years. Suppose I measure all three, and the trial ultimately shows a reduction in all of those outcomes (p=.04 for each). With Bonferroni etc., the trial would report a "null" effect across the board, even though these outcomes are all consistent and mutually reinforcing, and the evidence for the treatment is way stronger than if I had only collected evidence on cholesterol levels at 1 year.  It makes no sense to me that any single outcome by itself would have been statistically significant, but just because, in the past, I decided to collect more and better evidence, now the treatment has "no effect"?

I would say there’s a step change but a tiny one. About the same difference as 5.5 Codex to 5.5 ChatGPT Pro. Enough to merit using once in a while, but not an obvious and dramatic improvement.
I’m in a group chat with economists in a variety of fields - all are in 90th percentile or greater of ai use in the profession Fwiw no one’s noticed a step change from 5.6 to 6. Bottleneck for Econ research is not what the models are being rl’ed on. Might be that economic research is not economically valuable, or at least not valuable enough that labs are willing to pay the high price for those rl environments relative to those for example for financial analysts
