Some useful reports for stadium and arena researchers…

Judith Grant Long’s data on full public cost of stadiums and arenas

Where most “stadium cost” charts just rely on self-reporting by teams, Harvard researcher Long has actually attempted to calculate the public and private costs of every major-league stadium and arena in North America, including hidden subsidies like free land, lease breaks, and tax exemptions. Long is currently working on a book on this subject (UPDATE: it’s out!); until then, these archives of her research are the best source for complete cost information.
