Econ seminar culture is built on the assumption that the audience knows something that the speaker doesn't, and that the speaker values that information. A very important thing the audience knows and the speaker doesn't: Is the speaker making any sense at all? If nobody has any

Happy and honored to receive this award, and even better with Avinatan and Ran. Looking forward to many more years of joint work in market design. Thanks to the award committee, to our awesome collaborators, and to the administrators who trusted their markets with us.
Incredibly honored to receive the inaugural @INFORMS AMD Market Design Impact Award and especially delighted to share it with my best friends and coauthors @AssafRomm and Avinatan Hassidim. 1/2

Palestinians killed his wife, both of his daughters, his brother, and even his dog. They starved and tortured him for 491 days. They paraded and humiliated him at their last opportunity, forcing him to read lines in some sadistic show they put on. Eli Sharabi didn鈥檛 know what

5/5 However, non-substitutablities can create a situation where no stable allocation eliminates justified envy, and vice versa. Here is the link again: https://t.co/vj7lYRRI7p

4/5 Our main theorem states that if choice functions are substitutable, there there exists an allocation which is both stable and eliminates justified envy (and you get to it using "Deferred Acceptance").

3/5 We take choice functions as fundamentals, consider the *revealed* priority relation, use it to define what is *justified* envy, and then to determine when an allocation eliminates justified envy. In matching-with-contracts environments this is different from stability.

2/5 Stability is about deviations. Elimination of justified envy is about adherence to some priority relation. In simple environments, these end up being the same (hats off to Abdulkadiro臒lu and @tyfn_sonmez). In complex environments, things become more complicated.

1/5 What's the difference between stability and the elimination of justified envy? Our short paper (just published in GEB, only 10 pages) clarifies the difference: https://t.co/vj7lYRRI7p Thanks Al Roth, @RShorrer32397, and the editorial team! (short summary below)

Classic X: Everyone on my feed is horrified because some paper possibly shouldn't have got through IRB, and the econ job market is possibly zero-sum (but maybe not). Good for them. #BringBackTheHostages
Wow. (It's not clear that the boost to downstream outcomes like flyouts could hold in long-run equilibrium, or that added visibility really is the mechanism driving it. But still, pretty striking, QED!)

Amazing. Lying without a shred of hesitation.
MUST WATCH During an interview with a Norwegian journalist, Hxmas leader Osama Hamdan was questioned about the killing of civilians during the October 7th massacres. When Hamdan falsely denied the accusations, the Norwegian interviewer presented him with videos showing his own

To be absolutely clear: the students in the encampments are racist and ignorant, but that's not the problem. The problem are the universities who are not doing everything within their power to stop this.

I think you should consider well your choices. Had a similar thing happened at my university against Arab students, I would have left the day after and would never look back.

Here are my thoughts on the situation in US colleges: I will *never* be able to attend a conference or give a seminar at a location such as Columbia without adding an intro about the deep shame that they should feel with respect to April 2024. And, to faculty at these places,

Tweets from US colleges become more and more ludicrous by the moment. It's a race to the bottom, and elite colleges take the lead.
Public Safety is denying access into Columbia and Barnard campuses. I am a low income student that relies on my dining plan to eat and I no longer have access to any dining services, along with many of my peers. Columbia is starving its students, has checkpoints to check bags

How is this year different than other years? Yesterday as we read about freedom, we kept thinking about our 133 brothers and sisters still hostages in Gaza. Truth be told, there isn't a minute we aren't thinking about them. #BringThemHomeNow

I want to send a public message to Mr. Cas Holloway, the COO of @Columbia University: Cas, you're are really great guy. I know it. I saw it in your eyes today. This is why know that, deep-down, you know I'm right. You may not like my style, but I know you agree with almost
