A Nobel medal

BREAKING: The Nobel Prize in Physics has been awarded to John Clarke, Michel H. Devoret, and John M. Martinis "for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit"

Stay tuned for more.

Thrilled to start a long-term academic visit today at UC Chile’s Instituto de Economía: https://economia.uc.cl/
In Santiago/Chile/LatAm? Let’s connect: ideas on the table, wine (or pisco sours!) on the side. Bring your priors; we’ll update the posteriors & boost our networks' R²!

Acabamos de ver NUBE de Jose Vidal en el Teatro Municipal de Las Condes: nos encantó a todos, pero nuestra hija de 7 años (que hace danza moderna) quedó completamente cautivada. Pura poesía en movimiento! www.tmlascondes.cl/n...

And a delight it is, indeed!
(Also a timely nudge to @nobelprize.bsky.social Econ Committee: Pakes’s toolkit reshaped how we study markets; Bresnahan–Pakes–Porter as laureates in 10 days would fit the evidence. P.S. Long overdue Nobel for EIO!)

Mi se șoptește că Păturică a ajuns ditai prof la Școala Națională de Studii Politice și Administrative, unde va preda „dezvoltare economică”. După ce-a dezvoltat ministere până le-au ieșit fulgii, urmează dezvoltarea studenților — cei scăpați nedezvoltați de Bulai & Pieleanu.

Straight up asking public universities to set up governing structures to violate the first amendment

My petty gripe: not only am I losing my livelihood to AI – now it’s stealing my em dashes too The humble em dash is being used as a tell that something is written by a large language model. But it’s James Shackell’s favourite piece of punctuation, and he’s not ready to lose it

A Nobel laureate on why stablecoins may be nothing of the sort Payments systems must be built on public infrastructure, not speculative tokens, writes Jean Tirole

“Stablecoins, like money-market funds, project security but can collapse under pressure,” argues Jean Tirole in a guest essay. The Nobel laureate explains why these digital tokens are riskier than promised

De la subida por Parque Mahuida, entre bosque verde y montaña, a la bajada hacia Caleta La Reina para un almuerzo simple-perfecto de mariscos (¡con música chilena en vivo!): del mapudungún al chileno, hasta este gringo cacha el ritmo, po. #SantiagoDeChile

Persistent habit alert: bashing math diagnoses the basher, not the discipline. And BTW, 𝑎𝑙𝑙 𝑚𝑎𝑡ℎ can matter: the treatment effect is operator-dependent.
My 2¢: apply the 'Terry Tao move'—master rigor, then recalibrate intuition in situ. That's how econ gets traction.

Bernanke, Cochrane, Greenspan, Mankiw, Paulson, Rogoff, Romer, Rubin, Summers, Yellen, etc & me: "allowing the removal of Governor Lisa D. Cook while the challenge to her removal is pending would threaten that independence and erode public confidence in the Fed." www.supremecourt.gov/DocketPDF/25...

Creating a database of motivated proofs It’s been over three years since my last post on this blog and I have sometimes been asked, understandably, whether the project I announced in my previous post was actually happening. The ans…

Our project is to create a database of what we call "structured motivated proofs". For more details about this, and for information about how you can get involved (if you have suitable skills), see a blog post I have just written.

Late-night show hosts decry suspension of Kimmel’s show: ‘Blatant assault on freedom of speech’ Stephen Colbert, Jon Stewart, Seth Meyers, Jimmy Fallon and David Letterman criticize ABC’s parent company, Disney, and FCC chief, Brendan Carr Late-night show hosts Stephen Colbert, Jon Stewart, Seth Meyers and Jimmy Fallon and former host David Letterman have all rallied behind Jimmy Kimmel following ABC’s decision to indefinitely suspend his popular late-night show after his comments about the rightwing activist Charlie Kirk. In his opening monologue on Thursday night, Stephen Colbert mocked executives at Disney, ABC’s parent company, for caving to threats from Brendan Carr, the FCC chairman, when they pulled Kimmel off the air.

First ever sustainability-linked sovereign bond supports the Republic of Chile's climate ambitions Societe Generale was active bookrunner and joint sustainability structuring advisor of first-ever sustainability linked sovereign bond.

Happy Fiestas Patrias and Independence Day to Chile --
which issued the first ever sovereign sustainability-linked bonds (March 2022).
These ideas can be valuable at COP30 or beyond.

Au passage, valable aussi pour la 🇷🇴, où Moody’s maintient une perspective négative. Sans vision de long terme — avec, entre autres, réforme éducative et investissements publics rentables — les spreads s’élargissent. Clé : crédibilité + compétences (NB. pas d’austérité folle!).

Crise de la dette : le regard de Jean Tirole, prix Nobel d’économie La notation de la France par l’agence Fitch est descendue de AA- à A+ ce week-end. La crise de la dette est là, et elle est aussi très présente dans le débat public en France, mais pourquoi aucune solution n’est-elle encore mise en place ?

Excellent intervention de Tirole : la dégradation de la 🇫🇷 révèle un déficit de perspectives. Réponse : trajectoire budgétaire crédible + investissement public sélectif (tech/IA/biotech) + choc d’éducation (fondamentaux) + coordination UE/internationale.

¡Fabuloso #CancioneroChileno ‘25 en el Teatro Municipal de Las Condes! Gepe+ Andrea Tessa+ Javiera Parra, 30+ artistas y emoción pura. Mención especial para Camilo Salinas: absolutamente soberbio — director musical brillante y pianista tremendo. Cerramos con #GraciasALaVida. 🎥👇

Reacție critică după îndemnul lui Gabriel Liiceanu la „luciditatea majorității cetățenilor români”: „Are ghinion bietul Bolojan” - HotNews.ro Theodor Paleologu a reacționat ironic la articolul de opinie al filosofului Gabriel Liiceanu, găzduit de HotNews, afirmând că paralela făcută între România

2/2 Vestea bună: există critici ai „exaltării” între 'intelectualii publici'. Vestea rea: ăia-s la fel de servili: îl țin — „faute de mieux” eternă — pe musiu Petrov la piept. Cultul rămâne, idolul se schimbă: înlocuiți efigia, păstrați reflexul pavlovian.

Autorul istoricului „Apel către lichele” revine cu un îndemn la „luciditatea majorității cetățenilor români”. „E o șansă pe care poate nu o vom mai avea vreodată” - HotNews.ro Măsurile guvernului Bolojan sunt necesare și vor putea asigura schimbarea vieții românilor în bine dacă „i se vor da anii necesari pentru a traversa deșertul

1/2 Un sfertodoct la limita ridicolului, cu aplaudaci între miorițe, îl unge pe musiu Bolojan „Moise cu Excel”: Oradea=Paradis, restul „debusolați”. Furtună PR într-un țoi de țuică. Excel drept cădelniță, „cifre sacre” ca dogmă; scepticismul devine erezie.

Trump truth social post: "I love the smell of deportations in the morning..." Chicago about to find out why it's called the Department of WAR. Stupid "Chipocalype Now meme with Trump's head pasted onto Lt. Colonel Bill Killgore's body."

Everyone knows he's crazy and no one takes anything he posts seriously but declaring war on Chicago is next level.

In theory we rank optima; in practice we triage equilibria:
