Expensive Tickets

From time to time there are media reports of high prices charged for tickets to sporting events and concerts.

The organisers appear to sell all their tickets rather quickly, but tickets are still offered for sale by secondary suppliers that charge much more than the nominal charge.

That suggests to me that the organisers of the events do not charge enough in the first place. Raise the official prices and the 'tickets touts' and internet re-sellers would no longer flourish.
