Some good coverage of my working paper on housing filtering in The Atlantic today. The paper itself, The Downmarket Impact of New Multifamily Housing: Evidence from a Honolulu Condo Tower, is available here: papers.ssrn.com/sol3/papers....

what if i told you, through the power of forensic analysis, we are closer than ever to knowing the exact Far Side cartoon that is making Sting smile in this iconic photo. 🧵 👇

Trump administration drops its appeal of court order blocking $1.2-billion UCLA settlement

Very cool how productive everyone is getting with new AI tools, I think, as I listen to Brownsville Girl for the fourth time in a row.

Has financial literacy been declining or are smartphones changing the way we answer surveys? I was on Marketplace yesterday to talk about how smartphones are making it more challenging to gauge knowledge on surveys. Longer thread coming soon! Check out our full study here: lnkd.in/guiqHmKW

Tour de force on just exactly what has gone on at Texas A&M for so many years from Chris Hooks in @texasmonthly.bsky.social: www.texasmonthly.com/news-politic...

Honestly, tons of academics who I greatly respect don't realy understand AI including - what it does, how it's evolving, how it's affecting research. That's bad.

This year's Empirical Management Conference is at Stanford, May 27-29! Send us your best papers! Details and submission form here: worldmanagementsurvey.org/emc2026/ JOIN US!! It's fun, I promise! @raffasadun.bsky.social @johnvanreenen.bsky.social @renatalemos.bsky.social @nickbloom.bsky.social

Despite the negative framing in this article, this sounds like a very promising set of moves by the EU Commission on reforming some harmful and failed digital regulations.

Star ratings are hard to ignore. Even when we’re looking for quality, our brains steer us toward cheaper stuff online. Christopher Mims explains why.

Interesting reporting from @bencasselman.bsky.social, suggests Instacart is performing (or allowing) quite extensive personalized price discrimination.

Acts done out of love, Nietzsche once said, stand beyond good and evil. If this is what art amounts to, we should be grateful to Alice Munro for reminding us to be properly frightened of it. muse.jhu.edu/pub/1/articl...

In honor of #GivingTuesday, my wife & I are matching donations (up to $20K) to the ASFOP Teega Wende Orphanage in 🇧🇫Burkina Faso🇧🇫, which supports over 200 orphans and we have supported for over a decade. 1/2

I don't know if Texas deserves to be in the playoffs, but I do know what all the other playoff teams are hoping for.

Some news: I will be spending this entire 2025-26 academic year located in Paris, visiting the local universities and participating in the research community here. If you work in Paris or are just passing though in the next year, please reach out, I'd be happy to meet up! PhD students especially!

This is an interesting set of academic research papers about the increasingly key debate of when AI should be used to label data (an expensive task we use humans for) Yang et al show that AI answers are quite different than human, but Briggs finds it may be because AI is better than human RAs!

I think Southwest Airlines should revert its website to what they had in 1995

Yes it is.

Attention IO job market candidates: Sometimes speakers in the CMA's external economics seminar series have to cancel at relatively short notice. We would love for these slots to go to JMCs to present their job market paper. Drop me a message if you are interested or share with those who might be.

❗❗❗🚨🚨🚨 Next @cepr.org IO Virtual Gathering is taking place on NOVEMBER 7 at 2pm CET. 1st hr is dedicated to JM presentations by IO candidates graduating from Eur / UK schools. If interested, please submit a draft of your JMP & CV at: t.co/aUTPTWSten by OCTOBER 26! 🚨🚨🚨 ❗❗❗ #econjobmarket

This paper shows that you can predict actual purchase intent (90% accuracy) by asking an off-the-shelf LLM to impersonate a customer with a demographic profile, giving it a product image & having it give its impressions, which another AI rates. No fine-tuning or training & beats classic ML methods.

On one hand: don't anthropomorphize AI. On the other: LLMs exhibit signs of gambling addiction. The more autonomy they were given, the more risks the LLMs took. They exhibit gambler's fallacy, loss-chasing, illusion of control... A cautionary note for using LLMs for investing without guardrails.

It looks like he didn't share it on Bluesky, so I will. @afinetheorem.bsky.social has written an excellent review article covering 7 recent books on the economics of AI that serves as an excellent overview of this topic. Highly recommended! kevinbryanecon.com/BryanAIBookR...

I can confirm that the cuisine in France is on another level

🚨*New research*🚨 Together with Tai Lam, Nicolas Padilla, and Anja Lambrecht: we study the impact of LLMs on user behavior across the web. We use a large and detailed panel of user-level online browsing from 2022 – 2023 and study how consumers' behavior changes after they adopt AI tools.

Eight rules to regain trust in universities. All can be done today. They're absolutely not the core beliefs about the role of the university for some faculty right now, but are essential if we're to contribute to the trusted production and diffusion of knowledge. kevinbryanecon.com/trust.html

This is a very serious problem, not only directly because of the corruption alleged, but because it undermines and harms confidence in the entire process. www.wsj.com/politics/pol...

Working for the University of California while also living in France - I have reached truly elite levels of spending time dealing with inscrutable bureaucracy and filling out forms.

Killing SB 79 will make Los Angeles a less affordable, less sustainable place -- it'll keep us on the same trajectory we've been on since SB 827 and SB 50 were killed almost a decade ago. Why is the mayor going out of her way to oppose it? There's no excuse for this.

Terence Tao (@teorth.bsky.social) has written a thread on Mastodon about the impact of the federal grant freeze to UCLA, particularly to his own field of Mathematics. UCLA's IPAM (Institute of Pure and Applied Mathematics) could shut down entirely mathstodon.xyz/@tao/1149568...

I can't stress how damaging this is. Destroys trust in core government statistics.

The Justice Department fired two of its most senior antitrust enforcers after internal disagreements over how much discretion their division should have to police mergers.

🚨Free data alert!! 🚨 Please share. Large new dataset of Amazon product reviews, including full text and photos and product characteristics, with individual *reviews labeled as fake reviews*. I believe this is the first publicly available data of this kind. github.com/bretthollenb...

Extremely informative video. An economist would call this an equilibrium unravelling -- makes a lot of sense why so much needs to be gated now. If webcrawling turns a non-excludable product into a competitor, then businesses will do their damndest to make it excludable...

far be it from me to tell scientists how to do their jobs but i feel like there might be value in surveying the <365 hot dogs per year demographic

Nice article summarizing new research by Sherry He on the impact of sustainability labels on Amazon on product demand.
