This is a market created and maintained through economic incompetence.
More after the break.
"As I have written many times before, economic logic tells us there are only two conditions that can create a secondary market for concert tickets selling above their list price: 1) the number of concert tickets being offered for sale is too low relative to the number of fans who want to attend the concerts of popular musicians, and/or 2) concert tickets must be under-priced relative to their true market price. And I would suggest that both of those conditions are completely under the control of the artists, and their managers and promoters, in which case we are led ineluctably to this conclusion: musicians and their representatives who are 100% responsible for the conditions that guarantee a secondary market where concert tickets to Adele to Beyonce concert are sold above their face value."
This is simple stuff, but apparently impossible to understand for the artists, and promoters. Really, I suspect they do not want to sell the tickets at fair market value because it would make the seats very expensive, due to the highly limited supply of seats. The artists do not want to play one venue for multiple days, they want to play one day, and then on to the next venue. The result is high demand, and low supply, which is then made crazy by under pricing the tickets.
The solution is to allow people to bid on tickets in an auction format and let the price settle where it will for the seats. No scalper will buy in this forum since it is likely the price will be true market value, and there will be no reseller profits to be had.
