The interview begins with a discussion of the financial impact of sports stadiums. Noll makes the point that for a stadium to just break even it has to be used around 250-300 nights a year! This is something to keep in mind when you hear local councils arguing that their city should have a new sports stadium. Ask yourself, Will it be used 300 days a year?
The above comments refer to multiple-use stadiums. As for single use stadiums, rugby/cricket here in New Zealand, baseball/football in the U.S., Noll says,
Baseball and football stadiums, however--there aren't any that have been substantially subsidized where the local community has received anything remotely resembling a reasonable return on investment. They are financial black holes.
