Price Theory Take on What Egg You Should Buy

During dinner my friends debated about what kind of egg one should buy. Some says that big (XL/jumbo) eggs is painful for hens. People should buy small eggs. One of the first-year student speaks up If everyone goes to buy small eggs, producers do notice that large eggs don’t sell well. Then hens that lay large eggs will lose their commercial value. Farmers will kill them and replace them with hens that lay small eggs....

Do More Expensive Violins[Wine] Sound[Tastes] Better?

In the world of musical instruments and wine, quality is more subjective, and price signals more than just quality. It’s for sure not quasi-linear utility. Sometimes, the more expensive, the merrier. Soloist evaluations of six Old Italian and six new violins Link: https://www.pnas.org/doi/10.1073/pnas.1323367111 10 renowned soloists each blind-tested six Old Italian violins (including five by Stradivari) and six new during two 75-min sessions—the first in a rehearsal room, the second in a 300-seat concert hall....

Bach's Partitas (BWV 1006, 1013)

Partita is a Baroque-era instrumental composition, essentially a suite or collection of stylized dance movements, often starting with a prelude and including dances like the Allemande (German dance in 4/4), Courante (lively French/Italian in triple meter), Sarabande (A slow, dignified Spanish dance in triple meter), and Gigue (A fast, energetic dance of English/Irish origin). These form a coherent whole for a solo instrument or small group, most famously seen in works by J....

Rite of Spring conducted by Klaus Mäkelä at Carnegie Hall

“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....

Ashkenazy's Rachmaninoff G Minor Prelude

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....

The Chernobyl Speech

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....

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....

The University Symphony Orchestra Presents Tchaikovsky's 5th Symphony

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....

Nutcracker by Christopher Wheeldon and the Joffery Ballet

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)....
