Big data show that minority drivers are 24–33% more likely to be cited and paid 23–34% higher fines, not explained by differences in offense rates, accident risk, or re-offense rates.

It turns out that certain combinations of tau and alpha are consistent with risk mattering less.
Surprise: the model also provides an explanation for the uncertainty effect, a finding that Uri Gneezy, @johnlist.bsky.social, and I wrote up 20 years ago. academic.oup.com/qje/article-...

Our new study just out in the @nber.org. We use a natural field experiment from my time back at Lyft to show that nonlinear pricing isn't just a contract design problem. It's a behavioral intervention problem too.
Organized by @johnlist.bsky.social (UChicago) and Robert Metcalf (Columbia), AFE 2026 brings together innovative work shaping economics, policy, and business through real-world experimentation.
Congrats on the new job! And, looking forward to my visit!
Some ideas change the world. Most don't. This isn't because they are bad ideas. It is because they never had the ingredients to scale in the first place.
Honored to be speaking on this crucial topic at the Nuremberg's Historic Town Hall next month. Join me if you can! pretix.eu/nim/johnlist/
Big Announcement! I'm thrilled to let everyone know that the Chicago School in Experimental Economics is heading to Buenos Aires! This edition of CSEE will take place November 4-8, 2026 at the Universidad del CEMA.

I'm sticking with the experimentalists. It's not denial or blind positivity; it's refusing to let sadness or outrage freeze us into inaction. There's work to do, and it starts and ends with being humane humans.
Because every experiment starts with optimism. You have to believe something can be better before you will bother testing it. Pessimists do not run experiments. They have already decided on the answer.
I have received an unusual number of DMs on what's happening in the US. When I reflect on recent events, I am deeply saddened but find some comfort in thinking like an experimentalist.
Why?
Munich in September, great colleagues, and a field that matters. If you're working on economics of education, please join us at the CESifo Economics of Education conference!
Rick and Ludger (woessmann.bsky.social) always put together a very stimulating conference.
Alright everyone I heard you! We have nearly 1000 applications to the CSEE and we are not even to the deadline!
This means two very positive things: first, experimental economics is thriving (and more!). Second, we need to do more of these summer schools.
Latin America, you're next—stay tuned!
The deadline is here! Last call for applications to the Chicago School in Experimental Economics in Japan. This free summer school will take place June 22–26, 2026 at the University of Osaka.

Economics is really for everyone and everypup! Here is @drdanasuskind.bsky.social asking John Nash if she wants to go to the Economics department today.
If only my own students would get this excited about economics!
Very kind, thanks so much @markgsheppard.com!

What hits home runs in the minors but strikes out in the majors?
Most pilot programs.
They dazzle in pilots and flop at scale. My new study (ideas.repec.org/p/feb/natura...) offers a model for designing interventions that anticipate scaling challenges early.
Let's make scaling a scientific object!

Excited to announce that this year's Advances with Field Experiments conference will take place at the University of Chicago on September 17-18, 2026.
@johnlist.bsky.social and I will send out a call for abstracts early in the Spring.

My FOMO has now been maximized...by a picture just sent! I had to miss this year, but the AEAs are always a favorite, largely because of the brilliant economists.
Pictured below are two of them on the market: Haruka and Danielle. Good luck to you both, keep changing the world and making us proud!
Thanks for sharing!
The effect of the left-digit in ride-sharing apps is significant—research by @johnlist.bsky.social et al suggests as much as $160M in profit is left in the table by not using it:

The holidays are a good time to step back from the research and remember what it's all for. Grateful for family, for colleagues who push my thinking, and for the chance to do work that might make a small difference.
Wishing you and yours a restful break and a bright 2026!
Excited to announce the 4th Chicago School in Experimental Economics is heading to Osaka, Japan!
Join us in June 2026 for an intensive week on frontier experimental methods. We'll cover my textbook (lnkd.in/eT9Ci-YT) and you'll have the chance to present your research. Apply here: lnkd.in/grVg68Qn
Wonderful conference! I urge all to mark their calendars.
Happy 1-year anniversary to the most incredible couple I know—Francesca & Eli! You two are brilliant, kind, and absolutely unstoppable together. Here’s to many more years of love, laughter, and changing the world in your own beautiful way.
Love you both!😍😍
Happy Thanksgiving everyone! Sending all my love.
Never forget that the best things at the table aren't on the plates. Today's data point: you matter deeply to someone. Let them know how much they matter to you. Wishing you a Thanksgiving full of exactly that.
The first foreign translation contract for my new Experimental Economics textbook has just come in—from Greece! There's a certain poetic justice here: given how many Greek letters fill the equations, they're essentially translating it back to the original language.🇬🇷📚
