OBAMA: He's got the White House looking like Saddam Hussein opened a Cheesecake Factory. It's gold everywhere.

as a founder of @RefineDotInk, discussion around this new paper is v. interesting! The results confirm that AI reviews are incredible for detailed, actionable feedback to improve a manuscript. If AI is better, should AI replace human review? Quick view from the trenches 1/

I’ve learned so much from Henrique and Yuhta working on this paper. Extremely excited to see our paper published! Many thanks to the editor and referees for a smooth process. A thread on the paper:
In their new paper, @smorgasborb, @xiaolin_econ, & Ishii tackle an important question: How should we make decisions using multiple information sources when we don't know their correlation? restud.com/robust-aggregatio… #REStud #EconX #EconTwitter

Theoretical Computer Science inherited an aesthetic for open problems from mathematics. Algorithms and computers are complex, and understanding them mathematically is difficult. The open-problem tradition has made TCS’s challenges clear and research easy-ish to evaluate. 1/7

Excited about this experiment: Daniel ran most of his published work through @RefineDotInk to find any hidden issues. Punchline: About 90% of issues surfaced were real. Happily none changed the main message of the papers. Will tweet about this more "officially" tomorrow but..
Replying to @littmath
But it's also the case that frontier models, appropriately scaffolded, are now pretty good at finding errors in informal mathematics. I decided to be the change I wanted to see in the world and run all my published papers through such a scaffold. 4/n

It's fulfilling to see this work in print. This paper has been "cooking" for about eleven years and then benefited from a smooth and constructive process @ecmaEditors. We hope people find this work thought-provoking and useful. For more on this topic...
Repeated games meet coalition stability. @SNageebAli and @CeLiuEcon characterize the power and limits of self-enforcing promises in deterring coalitions. They apply the framework to study the implications of wage transparency in labor markets. econometricsociety.org/publi…

See the impressive research agenda that @CeLiuEcon has built applying these ideas to matching, incl his job market paper in TE and his recent AEJ-Micro with Ziwei Wang and Hanzhe Zhang. Working with him is a blast. More people should do it. Link: celiu.net
