Does Ticketmaster not amplify prices and use perceived scarcity to drive up prices? They can due that because Live Nation is a monopoly in all but name.

If the tickets still sell out at the higher prices, than it is real scarcity, not artificial scarcity.

Each show has a set number of seats... it isn't an artificial monopoly, it is an intrinsic monopoly. People don't want to just go to A concert, they want to go to a SPECIFIC concert, and a concert venue only holds a set amount of people.
