How Taylor Swift fans broke economics

livemint.com:

Taylor Swift ended the European leg of her Eras tour on Tuesday at London’s Wembley Stadium, delighting nearly 100,000 cheering “Swifties"—but leaving many who couldn’t snag a ticket disappointed. One reason: the failure of the secondary market in tickets. Swifties have the same mental biases as the rest of us, making them reluctant to sell even at eye-watering prices.

Markets work on the basis of supply and demand setting a price. If there is more demand than supply, the price rises until fewer people are willing to buy and more are willing to sell. The basic problem is that Swifties mostly aren’t willing to sell, so the price soars until demand is destroyed—hitting well over $1,000 for many tickets.

I have firsthand experience: My eldest offspring snagged tickets months ago to take my besequinned wife (but not me) to the latest Eras concert. By this week the tickets were changing hands at more than eight times face value, and both agreed they wouldn’t buy them at such a high price. Given they wouldn’t buy at this price they ought to be, on traditional economic assumptions, willing sellers.

But both dismissed the idea out of hand—and not merely because trading tickets is trickier than trading shares. There probably would be some ludicrous price at which they would have parted with the tickets, but even a quick profit of eight times their outlay in a matter of months wouldn’t do it. This isn’t only about Taylor Swift tickets.
