(updates of) about me | Ariana (Haoyue) Tang

The past one and a half month was wild. But it’s fun and I’ve pretty much enjoyed riding the wave. Whenever I take some time off I get confused –– I’m like, cause I’ll have to do something. I’ve come to realize that being in a healthy state (both physically and mentally) is crucial for productivity. Investing time in self-care sessions and routine exercise plans turns out to be unexpectedly rewarding....

overtures

Definition Overture is a music instrumental introduction to a ballet or opera. During the early Romantic era, composers such as Beethoven and Mendelssohn composed overtures which were independent, self-existing, instrumental, programmatic works that foreshadowed genres such as the symphonic poem. In motion pictures, an overture is a piece of music setting the mood for the film before the opening credits start. Here’s a list of my favourite overtures. Ranked w.r.t. listening frequency:...

Shostakovich–the Return of Maxim, Op.45, No. 3, Valse

My impression of Shostakovich used to be largely biased with his chromaticism–the squeakily sharp Symphony No. 1 and the rich underlying emotions embodied in Symphony No. 5, as Apple Music Classical introduced His Symphony No. 5 (1937) and subsequent works express a fury and despair that he could not voice in public, although these works were often leavened with moments of sarcasm, irony, and cheeky allusions to his own private life....

Tchaikovsky Op.66 No.6, Grande valse villageoise (a.k.a. The Garland Waltz)

In 1889, when Tchaikovsky was 49 years old and at the height of his fame and powers, he composed his ballet The Sleeping Beauty–based on a romantic fairy tale. An elaborate waltz is performed and Princess Aurora arrives: No.6 Grande valse villageoise (a.k.a. The Garland Waltz) Undeniably, Tchaikovsky wrote the best waltz music. This waltz is just as popular as other Tchaikovsky classics, as well as the ballet suite–people hear it in Disney movie music tracks, Tom and Jerry, restaurants, and even elevators....

a thousand and one nights of oligopoly, collusion and antitrust | the Cournot model

Reading notes of Chapter 4 of ECONOMICS OF REGULATION AND ANTITRUST (2018), by Viscusi, Harrington Jr. and Sappinton. The theories of collusive and oligopoly pricing is powered by the mathematical tools of economic analysis and game theory. An oligopoly is an industry with a small number of sellers. The criterion of small is, “whether firms take into account their rivals’ actions when deciding on their own actions”. And we model this economic setting as a game–a list of oligopolies in the market as playes, whose actions includes setting prices or production quantities, and the actions of all players jointly determine the outcome for everyone....

once upon a dream, in Met Gala

Ariana Grande graced the 2024 Met Gala not merely as a guest but as a spellbinding performer under the grandeur of the Met’s storied arches. Clothed in a sheer green gown by Maison Margiela, designed by John Galliano, Grande radiated an ethereal charm. The gown, a diaphanous masterpiece, clung to her like morning dew, catching the light in a cascade of shimmering greens that seemed to paint her in the colors of a waking forest....

just in time! | why we'd do everything at the last minute

Happy Sunday! Today, I’m stepping away from the antitrust series to explore a lighter topic: deadlines–—the last-minute scrambles that somehow keep our world spinning.

Join me as we unpack the economics behind the ticking clock in our daily lives. deadline: a love-hate relationship Ever noticed how our daily tasks are relentlessly deadline-driven?...

navigating the antitrust maze with Adam Smith's invisible map

ECONOMICS OF REGULATION AND ANTITRUST by W. Viscusi, Joseph Harrington Jr. and David Sappington Chapter 3 Introduction of Antitrust | Reading Write-Ups Introduction: The Value of Studying Antitrust The essence of economics vibrates with the spirit of competition. While not utterly unconstrained—no, firms can’t simply dynamite their competitors’ facilities—we lean on competition as the quintessential engine driving favorable economic outcomes. But sometimes competition evaporates. Essentially, antitrust laws strive to enhance market functionality by nurturing and regulating competition....
