My angelic, autistic 12 year old daughter Annika drew this pencil and asked me to share it with you. She gets giddy when her content does better than mine, which makes me happy. Please share it far and wide to keep her fire for art going. We've just barely gotten it rekindled.

This edition of CSEE will take place November 4-8, 2026 at the Universidad del CEMA.  This intensive one-week summer school is designed to deepen scholars' understanding of frontier experimental methods. Lessons will range from designing and conducting experiments to analyzing and interpreting data to writing up your findings. The curriculum draws from my forthcoming textbook, Experimental Economics: Theory and Practice (amazon.com/Experimental-E…), and participants will also have the opportunity to present and discuss their own research. I'm honored to be joined by an outstanding group of lecturers: Gwen-Jirō Clochard (The University of Osaka) Jared Gars (University of Florida) Luca Henkel (Erasmus University Rotterdam) Justin Holz (University of Michigan) Sally Sadoff (UC San Diego) Julia Seither (University of Chicago) Karen Ye (Queen's University) Applications are now open to researchers across disciplines who work with experimental methods, want to apply them in the future, or teach experimental approaches. Priority goes to junior faculty, but doctoral and postdoctoral researchers are also welcome to apply. There is no program fee, and financial assistance for accommodations is available.

Violence doesn’t just drive migration—it reshapes saving behavior. In Exit and Save, I study how insecurity changes risk, liquidity, and exit decisions. Not so new, but current paper 👇

@cblatts A technical, not political remark, with empirical foundation: the most terrific thing is trust. Works like good health insurance ie grows the pie while lowering costs.

Agree that Greenland hullabaloo is probably just “Art of the Deal” posturing. Talk about something wild, anchor people on a terrible outcome, then hit them with a hard to refuse purchase offer. Quite frankly, acquiring Greenland in some fashion is terrific for the United States and arguably the world. It's just the manner in which Trump is doing it is incredibly damaging—certainly in the short run, and we will see what happens in the long run.

Hey @UberEats , when you deliver food to the wrong address and cannot rectify, you insist on charging the original customer that never received their food. Is that strategy or error?

The 2026 World Cup draw looks random, but it really isn’t. With forced hosts, confederation limits, and bracket placement for the top seeds, some teams are way more likely to get grouped together than others. Here's the outcome of 1 million simulated draws under FIFA’s rules.

@CartoonsHateHer @CostelloWilliam We need to work on the definitions. These words have many interpretations.

Relevant to my article in GQ today about "toxic masculinity." Straight women have a stronger preference for dominant men than straight men have for submissive women. Dominance is not an unfortunate side effect of masculinity--a lot of women prefer it. cartoonshateher.com/p/do-you-want-…
