Ceci dit avec 12 ministres sur 18 identiques au précédent gouvernement il ne fallait pas s'étonner... Rebattre les cartes dans le même groupe ne marche plus, je suis assez pessimiste sur la capacité d'un gouv de gauche à tenir face à des LR, Rennaissance et RN, on se dirige vers la dissolution ?

#EconSky On my way to the first European Economic Theory Conference to see many great talks! (and give mine)

Van der Leyen: this deal brings stability with a key ally The key ally: I guess it brought at least a month of stability?

The workshop is now over thanks to all participants! This was a nice and moving tribute to Yinghua, many shared nice memories and stories about him. It showed how he had a deep impact on market design in Europe and especially in France and how broad his interests were from theory to empirics

#econsky When I receive random emails from students around the world asking to do a visiting with me during the PhD

Très honoré d'avoir été membre du jury du Prix de thèse 2025 de la cour des comptes, félicitations aux lauréats pour la qualité de leurs travaux qui éclairent les politiques publiques et montrent l'utilité de la recherche scientifique dans ces temps troubles à l'international pour les chercheurs

#EconSky Trump admin sending letters to US scientific journals to bully them and cutting their funding. Restud:

#econsky #econconf What an amazing conference we just had in the best venue ever. All talks were great and it was again nice interactions between Econ CS OR and Maths/Stats

Merci maintenant la droite peut arrêter

#GenderStudies "Il n’y a pas d’obsession pour le genre dans les sciences sociales en France". Enquête sur la question du genre dans 120 publications scientifiques : elle est passée de 9 % en 2001 à 11,4 % du total en 2022" Bravo et merci @eollion.bsky.social ! www.lemonde.fr/idees/articl...

The main effect of tariff insanity: Uncertainty poisoning supply networks, degrading a lot of relationships at once. That scar tissue will linger for a long time. 1/

#EconSky #EconConf Very pleased to soon have the 2nd edition of our conference "From Matchings to Markets". This time in the beautiful IESC center in Corsica with a terrific program in Econ/CS/OR/Maths/Stats. Very much looking forward to seeing everyone there!

The glass half full part is that we wont have some obscure economist writing a book saying I was the only one to predict this crisis. Here easiest prediction ever

Trump to the world

About f time USA. Now come to me for some French protests advice, you will need merguez sausages, a metalic barrel to create a bbq and some ancient reusable French rally speeches like "Trump t'es foutu la jeunesse est dans la rue" or "Trumpe serre les fesses on arrive a toute vitesse"

Il y a le discours genre priorité IA et grand sommet national et il y a la pratique: le CNRS interdit l'utilisation pro des LLM non FR dans ses labos aux chercheurs on doit payer avec notre argent perso. Sachant que le substitut FR n'est pas de super qualité voila...

Less than a week to go to apply to the Paris Summer Institute in CSS. This year we will focus on LLMs and gen AI. It's entirely free, open to all disciplines across the social sciences, and our speaker's list is already wonderful and getting better. More info here: sicss.io/2025/paris/

#Econsky More research funding means more textbooks and higher utility !

What an article. A lot of incentives are misaligned here: rewarding hospitals based on survival after 1y, screening centers based on discard rate...etc.

💥 JOB (POSTDOC) ALERT 💥 Freshly posted: 4-year postdoc to work on applied market design at the university of Lausanne. Job add here: shorturl.at/AEV0D Spread the word!

For theory, I always thought that the story on how the proof was found is much more valuable than the super optimized backward engineered final version of it which, most of the time, kills the intuition but "looks impressive", I would love to see more on this in small "sketch" paragraphs

Can planting trees change the climate? @floriangrosset.bsky.social (CREST-ENSAE Paris) joins @talknormal.co.uk to discuss what history tells us about large-scale tree-planting & its impact on climate & economy Listen to this Vox Talk recorded at the CEPR Paris Symp: cepr.org/multimedia/c... #EconSky

Sit tight

#Econsky Now that our paper is published, I think it is a good time for a self promoting thread. I like it since when starting the project, I did not think this result was true. Thread with the help of chatGPT and some rewriting 👇🧵

New version of our paper with a lot of new results after 2 years of revision! Check it out #econsky #marketdesign I learned a lot in the process. A great team of coauthors. @crestumr.bsky.social

#Econsky Something I always thought about: are editors more careful about the decision time for tenure track people? Would it be interesting to allow TT prof to signal their status when submitting and we would require a different deadline for them (and maybe longer for others I do not mind)?

#Econsky Great opportunity here 👇 @crestumr.bsky.social

Congratulations to Philipp Strack of @yaleuniversity.bsky.social who was presented with the 2024 Clark Medal by Lawrence F. Katz at the #ASSA2025 Annual Meeting. #econsky aeaweb.org/about-aea/ho...

#EconSky Theoretical Economics is in interesting journal, you go all the way to acceptance before being ask to pay 12$/page to publish. What precludes us to withdraw and put in our CV "Accepted at TE but not published due to fees"?

#EconSky This is our yearly Econ Nobel lecture to present the works of this year recipient to colleagues and students. This is fairly accessible, do not hesitate to have a look at the recording!

Babies can have sleep regressions when learning a new skill. I am glad to announce that after 1 week of tough nights, our daughter has learned how to make fart noises and bubbles with her mouth. Looking forward to seeing our next crucial skill which requires sleepless nights

Don't know the particular story here. I just made me think about English editing which used to be extremely costly (AJE i used was 300e per paper). It was a barrier for some people not native and without funding. LLMs have changed that. Of course be careful and read the final version...

#econsky Preparing the reading list for my graduate course in #marketdesign for students to write a report. Any suggestion of recent papers in matching or auctions? (2yo max) self promotion encouraged. Any method welcome: theory, structural, empirical, experimental...etc

Can we at least ask him to randomize which country is chosen in a staggered way so that we can get a nice experiment?

"This time Julien you read your thread before posting to correct mistakes" and I did I sware I did. To my coauthors I am sorry when it is my turn to iterate on writing

My personal modest take and feelings about this.

Ecole polytechnique (also called X) has left X but is not joining bluesky either, just stays on Facebook and LinkedIn

Amazing how with babies you can be stuck in local minima of innovation. Not willing to change the habit which worked ok because you are scared that it would be much worse and when you try ut works a actually quite well and much better. Especially true for sleeping...

#econsky The first 3-way kidney exchange happened in France in 2024. This was the result of the French reform we worked on. "Advanced algorithms were used" = a R function of the ILP coded by my intern from Ecole polytechnique at the time presse.agence-biomedecine.fr/triplet-de-d...

One would normally want to wait longer to evaluate the effects of major policy changes, but the results of the first three days of #CongestionPricing in New York City are so striking that it is already possible to make some (at least preliminary) conclusions.

#Econsky the great Tommy is here :)

Very nice podcast indeed. I also gave my modest contribution discussing kidney exchange at the time of the French reform: open.spotify.com/episode/2vJg...

Le grand changement de Parcoursup ça a été surtout la possibilité des unis de classer leurs étudiants. Récemment enntendu d'un vice président d'une uni parisienne: "on est passé de 40% de réussite à L1 à 80%". Et comme il est rappelé dans l'article ce sont les formations qui classent
