Time given to review a paper should move from months to days.
Glad to see someone documenting what has been clear for almost a year now: AI reviewing beats human reviewing.
The upcoming challenge will be to decide when “enough is enough” because the AI reviewers are never satisfied, and if we cave to all their demands we end up with 150-page “papers” full of robustness checks and no clear message.
I'm pretty sure the review system as we know it is no longer viable or useful. We should start rethinking how to review papers.
Perhaps the reality is that academics attack AI because they think it will take away their own (and often only) identity. If things continue this way, there will be little space left for research as we currently know and do it, and this scares the shit out of every professor.

Please share this opportunity with your students. Going to start contacting applicants very soon.
I'm hiring an economics predoc at @ColumbiaSIPA, generally on applied micro projects, but with a large focus on the impacts of AI on economic outcomes using large-scale field experiments with many companies.
Please share widely: apply.interfolio.com/194121
Since 2000, U.S. home prices are up 227% and rents are up 146%. The median full-time worker's pay is up 121%. So wages have almost kept up with rents, but buying a house is becoming extremely hard in most of the country. And high interest rates do not help at.
More on this in our upcoming realab.blog/ post. Stay tuned for more!
We wrote about this in 2015: "95% of Airbnb properties boast an average star-rating of either 4.5 or 5 stars" See papers.ssrn.com/sol3/papers.…

I’m starting a Substack to write about data ecology, AI agents, and the data ecosystems we’re building and studying in my research group and at invocate. My first post explains why I think data ecology matters more than ever. Would love to hear reactions.

I’m on the Econ job market this year!
My job market paper shows that former coworkers help explain both who moves next and where they go. These connections are also associated with higher wages and longer-lasting matches.

I’m once again on the program committee for the Workshop on Platform Analytics (WoPA), taking place April 2–3 at UC San Diego this upcoming year. It’s a great workshop, and I encourage anyone working on platforms to submit a paper! The submission deadline is December 6, 2026.

PhD was my backup option :)
Students sometimes tell me they’re applying to PhD programs as a backup in case they don’t get a job as a software engineer or whatever. I get that the job market is rough but this is like saying you’ll start a company if you don’t find a job. Like starting a company, a PhD is the far *more* risky path and requires incredible grit over a long period. It isn’t just that you might realize after a couple of years that a PhD isn’t for you. The bigger risk is that you complete a PhD but end up overqualified on a niche topic after having spent 5-7 years on it. The research world, like acting, sports, music, or book publishing, is set up as a tournament, with lots of extremely competent people competing for a small number of highly desirable slots. We can talk about whether that’s fair and whether it’s inherent or can be changed, but as a professor I feel the least I can do is loudly and repeatedly warn people about what they’re getting into.
🚨🚨🚨 The call for papers for the 5th edition of the Workshop on Platform Analytics is open! Deadline: December 6: platformanalytics.org/
New substack from R.E.A.L.:
Downtown Chicago office employment GREW 10.8% between 2019 and 2023 — from 359,000 to 398,000 jobs. However, downtown L ridership is still down 35%.
These two facts are hard to reconcile, so we looked at the station level. Chicago has published daily turnstile counts for all 143 L stations since 2001, which we merged with Census LODES data on where jobs sit, block by block.
The stations surrounded by the most office jobs are running at 58% of their 2019 traffic. The stations with the least office exposure are at 70%. A 12-point gap, on the same rail system, in the same downtown, in the same year.
This isn't a story about jobs leaving the Loop. The jobs are still there. The people holding them are showing up two or three days a week instead of five, and that shortfall lands on everything downstream of the turnstile: lunch counters, transit fare revenue, ground-floor retail, and property assessments.
