The law of one price?
Jason Kottke informs us:
Ticket prices at the new Yankee Stadium are so high that if a New
Yorker wants to watch a Mariners/Yankees game from the best seats, it would be a lot cheaper to fly to Seattle, stay in a nice hotel, eat fancy dinners, and see two games.
Was it not Mises who said that the purchasing power of money is the same everywhere? Some of the price differential will come from the greater value of the business connection in New York. And maybe those seats are really good.
