Correlated Equilibrium in Fashion

The Maxinomics’ new video points out a new way fashion industry works. Instead of experimenting and betting on what the next hit style is, they just follow the authority: you might remember Pantone’s annual color, or: WGSN: trend forecasting From viral TikTok trends to shifts in global consumer behaviour, the world is changing fast. While anyone can spot a trend once it arrives, the most successful brands know what’s coming beforehand – and act on it early. That’s the power of trend forecasting. ...

Paper Reading Notes | The Economies of Superstars (Sherwin Rosen, AER 1981)

The market for classical music has never been larger than it is now, yet the number of full-time soloists on any given instrument is also on the order of only a few hundred (and much smaller for instruments other than voice, violin, and piano). Performers of first rank comprise a limited handful out of these small totals and have very large incomes. There are also known to be substantial differences in income between them and those in the second rank, even though most consumers would have difficulty detecting more than minor differences in a “blind” hearing. (Rosen 1981) ...

American ICONs by the Joffrey Ballet

Joffrey’s winter season show the American Icons is on. It features four contemporary choreographies in one night. Kettentanz choreographed by Gerald Arpino, with music by Johann Strauss Sr. Secular Games by Martha Graham Exerpt from Postcards by Robert Joffrey, with music by Satie Voluntaries by Glen Tetley, with music by Francis Poulenc A view into the kaleidoscope night: The night begins with — Teletubbies? Just kidding. The Kettentanz features Strauss Sr.’s cheerful composition — straightforward, happy, a little boring. As if it’s chosen intentionally to mimic the music we hear at ballet classes (but my standard is Tchaikovsky and Chopin, so judge not the pianist not, judge me). Kettentanz’s choreography feels less like an piece intended for performance and more like an etudes — a series of Grand Allegros, with dense technique showcase and seldom thinkings. You’ll see what I mean: ...

Fixing KaTeX Rendering in Hugo PaperMod

In my hugo papermod powered website where math is rendered by Katex, math blocks were silently failing to render mid-page. Everything after a certain point appeared as raw LaTeX. Here’s the fix. NOTE: The fix is generated by Claude. It works. But I’m not sure if the mechanism is 100% correct. But it works. Root Causes 1. Goldmark mangles math before KaTeX sees it Hugo uses Goldmark as its Markdown renderer. Goldmark processes the .md file first — and it escapes or corrupts characters like \, _, {, } inside math delimiters. By the time KaTeX receives the string, the LaTeX is broken. ...

Fixed effect regression — WG/DID estimator and their cluster-robust variance

In the early days of recording, the microphone could only cleanly capture a narrow frequency range. So engineers were like: we’ll just record what the microphone handles. Fair enough. Then the microphone got better. Then digital audio arrived. Then we could capture everything. But by then, scholars had already proven theoretically that music only contains those frequencies. The proof was very elegant. It won a Gramophone award. And to this day, grad students learn that a symphony is just a low-frequency hum with robust standard errors. ...

Talent Night — Himari plays Bruch's Violin Concerto No 1, conducted by Jaap van Zweden Plus To See the Sky

The symphony hall smells expensive on Feb 14. As ushers barely got the time to nudge the couples chugging off champaigns and sit down, the valentines day night concert began with Joel Thomson’s To See the Sky. The title of the work comes from my favorite line in CĂ©cile McLorin Salvant’s “Thunderclouds,” my favorite song on her album Ghost Songs: “Sometimes you have to gaze into a well to see the sky.” That line gave me so much hope when I heard it. It’s an encouragement toward introspection—she’s saying, Just gaze inward. The well might be your community, the loved ones around you, or your own soul. But the line also acknowledges that there are moments when life gets so hard that you can’t even bother to look up. I’m so prone to melancholy, and I struggle with anxiety and depression. Sometimes I live in that place. ...

Cosi fan tutte revisited at the Lyric Opera House

Lyric put up a goofy, lighthearted, modern production of Così fan tutte right before Valentine’s Day—doubling as the college night event. Up on the top balcony, we had three flutists sitting together. It was fun (and a little too noisy, as coined by my viola friend). (Lyric is doing Salome exactly on V-day. Nothing more romantic than a woman who, to put it in modern terms, gets swiped left on by a man and responds by having him executed and head on a silver platter) ...
