Abstract
Public subsidies for sports stadiums and arenas are often justified as a means to boost the local economy. The argument relies on historical local economic impact multipliers that misrepresent the effect of consumer expenditures on professional sports. Sports expenditures are subject to extraordinary consumer substitution away from other local expenditures, and they suffer unusually large first round leakages from the local economy because, inter alia, players export their earnings to the locale of their permanent residence. This note illustrates the extent of such leakages using information about the permanent residence of players in the National Basketball Association. While 93% of average employees live in the area where they work, only 29% of NBA players do the same. The illustration shows that a standard local economic impact multiplier exaggerates the stimulative effect of sports expenditures by over 400%.
