Swap Regret and Correlated Equilibria Beyond Normal-Form Games
Swap regret is a notion that has proven itself to be central to the study of general-sum normal-form games, with swap-regret minimization leading to convergence to the set of correlated equilibria and...

With rent control in the news, it’s a good moment to recall the research of @rebeccadiamond.bsky.social and co-authors. They show that strict rent control in San Francisco reduced the availability of rental housing, eventually *raising* rental costs. doi.org/10.1257/aer....

What is common knowledge in your field, but shocks outsiders? If two people have the same priors, and their posteriors for an event A are common knowledge, then those posteriors are equal.

Maybe journals should have a policy that data from anonymous sources will be verified by the journal before publication. The editor could contact the firm, to verify that it exists and that the study was conducted as stated. @aeadata.bsky.social is this feasible or am I missing something?

In hindsight, if a major material science firm had found a way to make its best material scientists 80% better, there’s no way it would stay anonymous. It would shout it from the rooftops, and put it in its earnings call. This is an argument that should have occurred to economists.

💡 Open science: A team of researchers at Shandong University has attempted to replicate Oprea (2024 AER). The results do not replicate. Oprea 2024 reported an online lab experiment, and found that prospect theory anomalies occur not only for lotteries, but also for deterministic 'mirrors'.

Emphasizing again that anyone who responds to "that's illegal" with some variant of "lol all law is meaningless you're a sucker for thinking that matters" is actively doing PR for Trump and helping him. Nihilism about the law is the best way to make sure that the rule of law dies a quicker death.

Re: United States v. Eric Adams, 24 Cr. 556 (DEH)
Mr. Bove,
I have received correspondence indicating that I refused your order to move to dismiss the indictment against Eric Adams without prejudice, subject to certain conditions, including the express possibility of reinstatement of the indictment. That is not exactly correct. The U.S.
Attorney, Danielle R. Sassoon, never asked me to file such a motion, and I therefore never had an opportunity to refuse. But I am entirely in agreement with her decision not to do so, for the reasons stated in her February 12, 2025 letter to the Attorney General.
In short, the first justification for the motion-that Damian Williams's role in the case somehow tainted a valid indictment supported by ample evidence, and pursued under four different U.S. attorneys is so weak as to be transparently pretextual. The second justification is worse.
No system of ordered liberty can allow the Government to use the carrot of dismissing charges, or the stick of threatening to bring them again, to induce an elected official to support its policy objectives.
There is a tradition in public service of resigning in a last-ditch effort to head off a serious mistake. Some will view the mistake you are committing here in the light of their generally negative views of the new Administration. I do not share those views. I can even understand how a Chief Executive whose background is in business and politics might see the contemplated dismissal-with-leverage as a good, if distasteful, deal. But any assistant U.S. attorney would know much i i red oril, in this ily. wing the perset arthro he Reside is ving to,
give him that advice, then I expect you will eventually find someone who is enough of a fool, or enough of a coward, to file your motion. But it was never going to be me.
Please consider this my resignation. It has been an honor to serve as a prosecutor in the
Southern District of New York.
Yours truly,
Hagan Scotten
Assistant United States Att…
