Congratulations to Stefanie Stantcheva (@s-stantcheva.bsky.social) of @harvard.edu, winner of the 2025 John Bates Clark Medal! #econsky www.aeaweb.org/about-aea/ho...

It's not perfect, but I'm pretty impressed at 4o's first take of me posing at a beach with a beach ball (same shirt as in the reference photo).

Democracy dies in deference

I don't think one is "better" than the other, traditional labs have many problems too. Plain vanilla experiments using convenience samples from "online labor markets" might become less relevant, but those are only a small subset of the broader category of online experiments

Hello, Bluesky! ☀️ We fund frontier research in Europe—bold ideas, unexpected discoveries and science that shapes the future. So it’s only fitting we’ve landed here. Sorry for being late. Follow us for updates on ERC funding, research policy, and our grantees' discoveries.

New: The largest medical A.I. randomized controlled trial yet performed, enrolling >100,000 women undergoing mammography screening The use of AI led to 29% higher detection of cancer, no increase of false positives, and reduced workload compared with radiologists w/o AI thelancet.com/journals/lan...

The new OpenAI model announced today is quite wild. It is essentially Google's Deep Research idea with multistep reasoning, web search, *and* the o3 model underneath (as far as I know). It sometimes takes a half hour to answer. Let me show you an example. 1/x

I find it funny how these amateurs at OpenAI are basically begging us, their paying subscribers, to test out the competition, especially when the competition is *free* with *unlimited requests*

In my BSc course, "Incentives, Politics, and Behavior," I am introducing students to interesting topics at the research frontier and making them think critically about causal identification. Today, we're doing "From Extreme to Mainstream: The Erosion of Social Norms," which feels almost too relevant

After you've been "used" to o1, 4o feels like a degraded experience. It's much more *intelligent*: better answers, asks for clarifications when needed, and follows instructions. It might be overkill for some tasks, but I've started getting annoyed when I'm out of o1 requests

An interesting aspect of o1 vs. 4o is that the former *really* pays attention to your custom instructions, whereas 4o mostly doesn't care. Ask for short, pointed responses and o1 will deliver; 4o mostly doesn't notice. Important to change "legacy" instructions created for 4o

**New working paper** How does the under-representation of females in Economics affect the career trajectory of female Ph.D. students? Sahar Parsa and I look at this in a new working paper by exploring sabbatical leaves taken by female professors at top-50 US Econ departments.

How can open-ended survey questions reveal deeper insights into economic behavior? Our completely revised paper (with new title!) explores recent developments, practical applications & best practices for designing & analyzing these powerful questions.

New paper: We combine evidence from a survey (correlational), bank spending data, and online experiments to show that job loss increases risk taking. Joint work with @abbysussman.bsky.social, Carlos Vazquez-Hernandez, Daniel O'Leary, and Jennifer Trueblood

Bluesky can be a fraught place to post about AI but it is worth noting that the buzz over o1 (& now o3) is not “hype.” We know o1 can actually do some very hard tasks (see my post) & o3 appears to represent a big further leap. They aren’t AGI, but will matter. www.oneusefulthing.org/p/what-just-...

This is the best advice for AI: Learn how it might be useful for you. Requires experimentation and an open mind.

GPT-4o keeps changing, but it's quite striking how eager it suddenly has become to have a conversation with me. Is it now explicitly programmed to create more "engagement" or is this an artifact of some other changes?

Using 4o with Canvas is such a pleasure for working with simple LaTeX documents

Last week’s AI + Economics Workshop in Zurich brought together some of the most talented researchers working on AI applications in economic research. This is our third year, and we have seen so many developments in what using AI means in economic research

This thread will document the starter packs that I have followed. My feed has been delightful and informative.

Don't ask people about their taste in music, ask for their Spotify Wrapped (revealed preferences!). I'm pretty sure my top 5 artist combination this year is globally unique.

Zero-sum thinking is a key mindset that shapes how we view the world. A little thread to highlight our work on its roots with @sahilchinoy.bsky.social, @nathannunn.bsky.social, Sandra Sequeira.🧵1/23 scholar.harvard.edu/files/stantc...

This newsletter will surge ahead only if we stay committed to the principles that define us, especially when the path forward challenges us. www.bloomberg.com/opinion/arti...

(1/7) 📢 New research alert! Even when people are shown clear evidence of #discrimination, it doesn‘t change their support for anti-discrimination policies. Read @kkrakows.bsky.social, @asmusletholsen.bsky.social, and my article in @ajpseditor.bsky.social to find out why: doi.org/10.1111/ajps...

You know it's finally a legit social network when you're keen to log in to see whether there's any developments in the current great debate about complexity and the nature of risk preferences 🚀

I disagree here. The papers are interesting as @aleximas.bsky.social has pointed out (bsky.app/profile/alex...), but differences in elicitation producing preference reversals predates Prospect Theory. If you don't know Lichtenstein & Slovic (1971) and Grether and Plott (1979), read below.

@hirshmansam.bsky.social and I ran this version and the results were starkly different. All of a sudden, people 1) responded to the weight of evidence and 2) reacted a lot to the degree of instability in the system. Beliefs were *much* closer to Bayesian.

Peak life for me is during *Easter* when you're on the mountain with comfortable temperatures during the day, allowing you to sit outside and drink coffee in the sun, and freezing nights to secure lots of snow

It's stunning how often something works super well using ChatGPT but when you try to scale exactly the same task using the API, literally using the same model and prompt, it utterly fails 😔

One of my all-time-favourite #Stata tricks is to create a macro that stores the current system date 🗓️, and plug it into the names of all my log files and output files: . global VERS = strofreal(date("$S_DATE","DMY"),"%tdCY!_N!_D") . log using "log_${VERS}" ☝️The log name is "log_2024_11_13.smcl"

At NHH, we're hiring an AP in labor economics this Fall: econjobmarket.org/positions/11... The application deadline is December 1, 2024. It's a truly fantastic place to do labor economics! Bergen has a lot of rain but the labor group is *fantastic* and on sunny days the city is second to none.

How should one design survey experiments for maximal impact in economics? Here's my slide deck from a workshop I gave in Uppsala earlier this year. drive.google.com/file/d/1yN4f...

Google Scholar PDF Reader is a really cool Chrome extension: Excellent AI-created outline makes it much easier to navigate the paper and all references are easily clickable. chromewebstore.google.com/detail/googl...

It is certainly true that non-economic concerns about immigration are very important. But an extensive research literature has tested whether economic concerns are exclusively a figleaf. It rejects that hypothesis. E.g. superb work by @ihaal.bsky.social & Roth—> www.sciencedirect.com/science/arti...

Amazing news, and wow, what a great pick for everyone in experimental and behavioral with Chris Roth (not here yet, I guess?)! Congrats 🥳🥳🥳 mailchi.mp/eeassoc.org/...

Hi everyone. I'm struck by the number of economists who have already gathered here, plus a rich spectrum of other thinkers and doers. I'm looking forward to learning from all of you.
