The Groyper Wars

“nobody goes there anymore, it’s too crowded” finance.yahoo.com/news/tech-st...

Entendez-vous l'Eco, présenté par Aliette Hovine, change de format. L'émission devient hebdo avec 1 partie consacrée à l'actualité et l'autre plus centrée sur l'éclairage que nous apporte l'histoire de l'éco Pour la rentrée, nous avons essayé, nous avons essayé... www.radiofrance.fr/francecultur...

I wrote an op-ed on the world-class STEM research ecosystem in the United States, and how this ecosystem is now under attack on multiple fronts by the current administration: newsletter.ofthebrave.org/p/im-an-awar...

I've been working on a new tool, Refine, to make scholars more productive. If you're interested in being among the very first to try the beta, please read on. Refine leverages the best current AI models to draw your attention to potential errors and clarity issues in research paper drafts. 1/

Harvard at war “If Harvard relied entirely on the endowment to fund its operations (ignoring investment returns), the total would be depleted in a little more than eight years.” #econsky #academicsky marketdesigner.blogspot.com/2025/06/harv...

New working paper alert: we provide a model of post-hoc rationalizations, driven by motives of (self-)esteem. We show how this can lead to groupthink, polarization, and a preference for echo chambers. www.ifo.de/sites/defaul...

am i the only one genuinely shocked at what is reported to be “the top econ journal in the world” ?

Congrats to Sergiu Hart, perhaps the quickest thinker I know, and a wonderful mentor, coauthor, and person, for being elected as an International Member of the National Academy of Sciences! www.nasonline.org/news/2025-na...

15 positions in AI at Paris Sciences et Lettres, computational social science and ethics very much included. I believe these are four-year "fellow" positions requiring some teaching during that term. #MLSky recrutement.psl.eu/en/pnp8wd2rbs

so are we good this time?

The political incentives to pursue the populist attacks on liberal symbols (immigrants, minorities, academia, science ...) grow stronger as it becomes clear that economic promises (DOGE checks) won’t be kept.

it takes a stable genius to upset at once big donors, retired voters, and GOP members seeking reelection. all in one move.

why did I never notice this before? “An International Society for the Advancement of Economic Theory in its Relation to Statistics and Mathematics”

to my economist friends. uncertainty on future prices increases expected present value of cash flows. but risk averse investors don’t like uncertainty which depresses stock prices. is there a way to nicely disentangle the two?

I find something paradoxical about the signal gate. Fascism thrives on a pretense of perfection, strength, and constantly attacks groups perceived as week: liberals, LGBTQ+, immigrants, intellectuals… that's what we are seeing now.

should the Game Theory Society join Bluesky? choose an answer. - yes - yes of course - what it’s not here yet?

We are pleased to announce an experiment intended to stimulate academic discussion and exchange, centered on papers published in Econometrica 1/5

bullshit in organizations is a Giffen good. the less resources they have the more they spend in terrible BSwashing.

enhorabuena querido Roberto!

the other place is on fire and this one is damn quiet. where has everyone gone? hiding in caves building some resistance network? i miss my online friends. send me the invite!!

so iterated deletion of dominated strategies works at the end, but only for bad outcomes ??

so … after having experienced extensively, I must report that the news are not better here than on the other place.

very sorry for all my friends and colleagues in the US. particularly at Columbia U. i hope everyone will remember this next time some US high level admin scolds europeans over “freedom of speech”.

in France we say “it wasn’t a failure, it just didn’t work out”.

Account on the other side was de-activated. Not an act of protest, not one of bravery, not even one based on moral principles. I just became too concerned about the consequences of what it means to share my data, ideas, political opinions, and real-time thoughts there.

🥁🥁 post-doctoral position in information economics and economic theory !! 🥁🥁 (rts / fwds appreciated)

Philipp is an amazing scholar. congratulations to him!

ok by comparing the two places i conclude the less i post the more followers i get. makes total sense to me …

excellent discussion. we’re in the good place.

Marrant cette propriété: si le chiffre des dizaines d’un carré est impair, le chiffre des unités vaut 6. Ça se démontre en posant (10b+a)^2 pour le nombre ba puis par récurrence pour les nombres à n chiffres. Il faut donc donner 2 pièces (ils ont tous les deux un nombre des unités de 8 francs).

i used to believe progress was unstoppable but a series of unfortunate world events convinced me to agree with Nietzsche that History is cyclical further than that, i would say that the very concept of time is what arises from repetition punk’s not dead God is not dead History is not over

so this is true …

big if true!

lots of econtwittos here. should i reserve this place for my 1/2 baked academic ideas (in 🏴󠁧󠁢󠁥󠁮󠁧󠁿) and leave my rants on how poorly my beloved country is doing to the other place (in 🇫🇷) ?

Is this place active?
