In this episode of Diving In, Justin Wolfers breaks down the economics of the Met Gala using two big ideas from economics: signaling and non-price competition. The basic point is simple: the high price of luxury goods isn't a bug in the system, it's the whole point. So instead of competing through discounts, brands must compete through spectacle: celebrity placements, giant flagship stores, fashion shows, editorial buzz, and events like the Met Gala — which Wolfers argues is a less-bad outlets for wasteful, non-price competition.

In fact, the real scandal may be that Met Gala tickets are underpriced. If brands capture enormous media value from the event while the museum gets only a relatively small share, then the Met may be giving luxury houses a very good deal. The stakes here go beyond fashion. This is a lesson in how markets work when buyers care about status, not just usefulness—and how that affects where money gets spent, what gets built, and how prestige shapes the economy around you.
