I feel like I have missed out on promoting our most recent school-choice experiment here: papers.ssrn.com/sol3/papers....

I am happy to say that now, 3 days after the conference and 3 days before I fly back, my body has adjusted to the Korean time zone.

Economists can be a tough crowd... I won't have that problem because I am in the very last session of the conference and everyone will already be out being a tourist.

Me and my fellow 1700 were cut out because of the y axis.

We're moving up! It's the KING of wands now 💫🪄🌟💫

Peter Achim (York) was visiting our theory group in Berlin this semester. Fascinated by the sophisticated regularity of our lunch schedule, he had his wife (an illustrator) create the following flow chart of decision making.

Have a look at the first edition of the Berlin Micro Theory & Behavioral Econ PhD Conference, and recommend your students to apply next time! sites.google.com/view/berlin-...

Please also show up tomorrow! We have another session remaining!!!!

Photo from the side... should have gone to the gym before the talk! Anyway, that was great fun! Thanks for letting me talk about my first experiment!

Looking forward to seeing all of you in Mannheim! This is an excellent line-up! (And I will also present.)

"What did you do last week?" Elon Musk asked. Well, I am proud to say that I managed to do an incredible amount of work yesterday--despite it being a public holiday! I disassembled several houses, and I helped desperate passengers out of an intricate parking situation!

I bought a customized cap with the embroidering "market design" only to make the joke to literally put it on when I say "putting on my market-design hat, I would..." and now I have lost it without ever making the joke!!! If your dealer in Görlitzer park is wearing this green cap... it's mine!

The Hausdorff Center at Bonn will host the Trimester Program on “Advances in Mechanism Design” next summer. Students and postdocs are invited to apply for extended stays during the program or summer school participation. Funding for travel and accommodation is available.

Our Monday theory seminar now comes with a walk and a piano performance.

Please join us for the 4-lecture mini course I will give on minimalist market design at University of StGallen this week. The course is open to all and available both in person and via zoom. See below for the registration info and the link in the next comment for the course slides.

Y’know there’s really nothing more Econ than reproducing something that happened in polisci a decade ago and claiming it as original.

🚨 REPLICATION REPORT UPDATE: One year ago, a tweet by John Holbein alerted me, @ollefolke.bsky.social, and @jopieboy.bsky.social to a paper with a shocking result about Sweden’s law criminalizing the purchase of sex.🧵

I'm looking for recent papers applying mechanism design to AI/ML. I'm most interested in tools from mechanism design that help solve problems in designing and evaluating AI systems. If you think it fits, please share!

Looking forward to the final day of our CRC retreat in Schwanenwerder @rationalitycrc.bsky.social

The interoperability issue introduces a non-trivial trade-off here. Consider an airline with a Boeing fleet. If they now buy airbus planes, they need to train pilots and maintenance staff and rearrange schedules. This impairs competition: you might want to lock-in and not just go for the cheapest.

Economic theory to the rescue.

This statement from the NSF is insane. Science is, in essence, designed to separate the true from the false. Understanding how falsehoods spread is key to the scientific endeavor. It is not a violation of free speech to be proven wrong.

I have a postdoc position in Behavioral/Experimental Economics available for 6 years, at the oldest university in Germany in beautiful Heidelberg. Please forward to anyone who might be interested! #EconJobs #AcademicJobs #HigherEd #Economics #JobAlert

Fixed it for #academia

What's up Mannheim? If you don't have anything better to do, drop by tomorrow at MaCCI Annual! www.zew.de/en/events-an...

New submission, new draw 🔮🔮🔮 ✨️✨️The six of wands✨️✨️ I cannot tell you how ready I am to "accept the praise coming my way gracefully because I've earned it!" 😁

The mechanism is a ‘Conditional Cooperation Mechanism' www.sciencedirect.com/science/arti... All contributions are conditional on other people’s contribution so that one’s own contribution encourages other people to make higher contributions, too.

After the AfD's surge on Sunday, far right parties are the most voted-for of any grouping in Europe, for the first time in history: www.economist.com/graphic-deta...

When you consistently point out the flaws in its mathematical derivation, this LLM breaks down quicker than any grad student. This is pathetic. It's 2025 and I still have to do algebra myself?!

I don't want to study Physics in Hamburg 😭 I just wanted to study the information provision in the dynamic assignment system and screwed up cancelling my applications 😭😭😭

I'm still living in a different country.

We’re happy to host the 1st European Economic Theory Conference in Bonn next fall! Submissions in all areas of economic theory are welcome.

The Federal Reserve is not as independent from the executive branch as we’d like to think. The NY Fed just cancelled this Thursday’s @aeacswep.bsky.social reception at #EEA2025 and withdrew from our summer fellowship program. Both support women and underrepresented groups in economics. #EconSky

Come on...

💥 JOB (POSTDOC) ALERT 💥 Freshly posted: 4-year postdoc to work on applied market design at the university of Lausanne. Job add here: shorturl.at/AEV0D Spread the word!

You can make the same picture with economics eating other social sciences, while CS is also eating into economic theory.

Wow😲 Amazing work by the authors of the comment! I think I fully agree with Shengwu here, including the opinion that often weird observations are attributed to behavioral preferences rather than mistakes (and vice versa, I may add). The good old "more research is needed" applies!

⏱️ Submission Deadline Extended: Jan 30 🛗 Behavioral Economics & Micro Theory reveal how decisions shape markets & society. Join the 1st Berlin PhD Conference (July 7–9, 2025) at WZB Berlin for insights, feedback & keynotes by Dorothea Kübler & Paul Heidhues. 🔗 More info: www.wzb.eu/en/events/1s...

HU Berlin, like many other German institutions (click link to see list), is "freezing" their accounts on X / Twitter. idw-online.de/de/news845520

I currently have a paper under review. Because I cannot wait for the decision, I downloaded a Tarot card app to get feedback that is about as random as a referee report. This is my card. Let's go! I can draw a card for your submission, too!

Planning your 2025 economics conference schedule? I've updated my list of general interest, IO, and theory conferences: www.igorletina.com/conferences.... New this year: you can generate a calendar file 📅 to easily track dates and submission deadlines of selected conferences. #econsky

Terrible contest design at the World Blitz Chess Championship 2024. The top 8 players after 13 rounds enter the knock-out stage. All the 8 players at the top were paired against each other and almost immediately agreed to a draw. That is not what spectators want to see.

A new first in my role as seminar organizer: I will announce a talk with the authors' musical abstract. Surprisingly, it's quite a banger (paper, of course, by Kfir Eliaz and Rani Spiegler): suno.com/song/67c8c9c...

I wrote an intro to the literature on simple mechanisms. Out now in the JEP. It’s a short (14-page) plain-language summary, designed to get students to the research frontier. 📈📉 pubs.aeaweb.org/doi/pdfplus/...

Today's edition of "📈📉 papers you should know" is from @jpolecon.bsky.social: The paper studies a game between a buyer and a seller. Simultaneously, the seller decides on a price to post for a good, and the buyer decides how much information to acquire about the good's value.
