“I’m in a mood for rite of spring”, I said “Go check Klaus Mäkelä’s Carnegie hall version. Let me show you”. My friend opened medici for me. FYI, the OG ballet of Rite of Spring depicts various primitive rituals celebrating the advent of spring (in Russia), after which a young girl is chosen as a sacrificial victim and dances herself to death. Klaus carried Rite of Spring to its extreme. His version embodies a raw, primitive connection with the nature, and the ultimate unrestness of human heart. Energy, passion, MADNESS! ...

Alla marcia, “in the style of a march”: Emil Gilels played this prelude at a front in World War II, in support for the Soviet militaryforces fighting in the war. The narrator says (in Russian): “Gilels is playing at the front, to remind us what the war is worth fighting for: Immortal music!” Wikipedia The prelude is the most performed and recorded piece of Rachmaninoff’s Op. 23 prelude set. Of all the versions I’ve heard (believe me, a lot of them), Ashkenazy’s version is coarse, rough, resilient, and strong. In my pov, though classical performers are somewhat free to interpret any piece written down, Ashkenazy’s way is the right way that it should be played.

A little reflection to Lu Ming’s speech at China Econ Annual Conference. Now the Chernobyl (the HBO miniseries) becomes relatable: At the trial of deciding who is responsible for the explosion, the scientist Legasov, instead of taking it easy by blaming the explosion to individual’s mistake, tried to point out the real flaw, which faces warning and threat from the official: [Judge] Professor Legasov, if you mean to suggest the ussr is somehow responsible for what happened then I must warn you that you are treading on dangerous ground. ...

Thanks to the internet, I’ve got to follow up with the latest heated discussion at China Econ Annual Conference. During the panel discussion, Professor Lu Ming expressed his concern for Chinese economic ecology: OG question (rephrased): Q1 how to balance academic research and policy research? Q2 how should young scholars plan their career path to do research that benefit society TL;DR: Q1 Economics research (in China) prioritizes methodological sophistication and journal publication over real-world relevance and policy impact. Journals’ incentives have distorted research toward complex but hollow models, misleading young scholars and stripping away China-specific realities. As a result, much academic work is disconnected from actual policy, sometimes even prescribing more regulation to fix problems created by regulation itself. ...

Today, the University of Chicago Symphony Orchestra plays our December Concert. We did Tchaikovsky 5th Symphony, and premiered Daniel Pesca’s Piano Concerto Up North. I played the Piccolo. For contemporary piece like Up North, there’s no melody so you can only count beats. It’s a very very stressful position to be in — because for a piccolo, there’s hardly cues from other instruments and I’m on my own. And after all, piccolo is a difficult instrument. It’s easy to make mistakes, and everyone hears it. ...

I was at the 2025 opening night of Joffrey Ballet’s The Nutcracker. OMG, right Christopher Wheeldon’s kaleidoscopic reimagining of The Nutcracker relocates the story to the 1893 World’s Fair in Chicago. The production shows off the iron-and-steam industrial charm of turn-of-the-century Chicago while blending Wheeldon’s contemporary choreographic vitality with the structure of classical ballet. What struck me most was how cohesive the narrative felt. Like Ballet often struggles with storytelling (sleeping beauty, I’m talking about you). This Nutcracker version builds Clara’s dream into a gently unfolding vision of family, yearning, and possibility. The Joffrey dancers carried it with luminous technique and an unforced theatricality that made even the fantastical moments feel grounded. ...

Professor Roughgarden came to University of Chicago! Day 1: Shill-Proof Auctions The paper Shill-Proof Auctions (https://doi.org/10.48550/arXiv.2404.00475) was presented the first day Professor Roughgarden introduced shill bidding from a broad angle. Reconsider the basic premise of the credibility of a mechanism. For instance, in a sealed-bid second-price auction, how can a bidder verify that they are truly paying the second-highest bid given that it’s a sealed bid auction in the first place? One credibility concern in auction is shill bidding, where the mechanism designer (the auctioneer) injects fake bids. ...

Professor Murphy teaches with a sharp, lightning-fast intellect that channels the timeless, foundational wisdom of the great economic thinkers. Problem No. 1: Nudge Problem No. 2: Why platforms running two sided market often charge the supply side Coming next: details and intepretations.

Costly Persuasion with Posterior-Separable Costs In the costly persuasion model, there is a cost $c(E)$ for experiment $E$. Assume it’s posterior separable: $$ c(E)=\mathbb E_{\mu\sim\langle E\mid\mu_0\rangle}[k(\mu)], $$ The sender chooses not only what information to reveal but also how much information to acquire. The entire problem collapses back into the familiar concavification framework: the sender’s interim value becomes $$ \hat v(\mu)=\mathbb E_\mu[v(a^*(\mu),\omega)]-k(\mu), $$ and optimal persuasion reduces to choosing a distribution of posteriors with mean $\mu_0$ to maximize its expectation. ...
