The local organizers have released a study of spending on Super Bowl 41 in Miami. Their bottom line, as reported by the Miami Herald: 112,000 visitors, spending $688 per day, for a direct spending infusion of $298 million. (The typical visitor spends about $200 per day - these are high rollers.)
Phil Porter has skeptical take on this:
Philip Porter, a University of South Florida economics professor, said $280 million in Super Bowl spending is too much for South Florida -- equaling 72 hours of total economic output throughout all of Miami-Dade County.
''In order to accomplish this, every sales line would have to double,'' Porter wrote in an e-mail. ``This is impossible. You'd have to sell twice as many cars, televisions, washers and dryers, etc., to accomplish this.''
Still, there's no doubt the game brought a major boost to the hospitality sector. Hotel taxes in Miami-Dade surged 15 percent in February and room revenues surged between 11 and 21 percent from Fort Lauderdale to Key West, according to state and industry data.
Porter's comparison is a useful reality check. It does miss the fact that hotel rooms and the like are fully priced during Super Bowl week. A decent chunk of the additional spending is a price effect rather than quantity.
Pat Rishe is also quoted: '"No question the Super Bowl attracted more [economic] activity than otherwise would have been the case in Miami that weekend," Rishe wrote in an e-mail. "But at the same time, Miami would not have been a ghost town either."'
The study was done by the Sport Management Research Institute, whose website has list of news references to their work, but no link to the study itself. A rather detailed executive summary is available via the Herald.
