It’s time for bad economics theater, Oklahoma City edition! Take it away, Greater Oklahoma City Chamber of Commerce:
Since the OKC Thunder came to town in 2008, Oklahoma City metro’s gross domestic product has grown by 41%, which significantly outpaced other similar-sized metropolitan areas that do not have an NBA team, supporters say.
Nope, that’s not how you do a proper correlation! For that, the chamber’s hired consultants from Applied Economics would have had to look at things like whether the pace of growth picked up from previous years once the Thunder arrived, to try to determine if that GDP growth is due to the team’s presence. Plus, if you’re arguing that this is a reason to spend $850 million in public money to build a new arena, it doesn’t even matter how much the Thunder affect economic growth unless they’d leave without one, which nobody is saying they would.
What else you got?
The study finds an estimated annual impact of $590 million, supporting more than 3,000 jobs. The study also estimates the impact of construction of the new arena, which would generate more than $1.3 billion during the construction period and support more than 10,000 jobs.
As usual, that’s not really economic impact, it’s just economic activity, which is totaling up any spending that takes place by anyone who goes into the arena, even if it’s money that would have been spent somewhere in town anyway. (There’s also probably a large multiplier built in: If the arena is in use 150 nights a year, which seems about right from looking at its calendar, then you’re talking about at least $200 in spending per ticket sold, which would be a lot.) And as for that $1.3 billion during the construction period, yes, spending $900 million on an arena is going to mean at least $900 million in money being spent, though the local goverment spending that same amount of money on something else — or even just returning it to taxpayers to let them spend it — would have an impact, too.
But don’t just listen to me, an economics journalist. While the chamber was presenting its consultants’ figures, outside the opposition group Buy Your Own Arena was holding its own press conference with economists from Oklahoma University, who said … okay, seems like most of the press preferred the scene inside, where there were probably snacks, but one quote did sneak into one local TV report:
“There’s a lot of research that says that shows that these sports arenas don’t pay off for host cities, and that’s not a positive return on investment,” said Cynthia Rogers, Economics Professor at The University of Oklahoma.
So what do the real impact numbers for Oklahoma City look like? Fortunately, we have Geoffrey Propheter’s 2012 paper on the impact of NBA arenas, which found:
Propheter did note that a handful of cities (Atlanta, Boston, Chicago, Denver, Indianapolis, and Oklahoma City) appeared to see income gains, but this was likely the result of “income transfers from the suburban area around the central city” — i.e., the same money was being spent in the region, it was just being spent downtown instead of at the local Olive Garden.
And Propheter later elaborated:
Oklahoma City, he notes, does show a correlation between building the Ford Center and an increase in resident income, but because it also built a whole ton of other downtown development at the same time, it’s impossible to say whether the arrival of the Thunder caused it or not.
So to recap: Oklahoma City landed the Thunder in 2008 after spending $89.2 million to build an arena and another $103.5 million to upgrade it, and the team was popular and the city continued to grow. This, the local chamber of commerce now argues, is why the city has to spend $850 million to tear down its 21-year-old arena and build a new one. Make your own selection of which logical fallacy is being applied here, there are lots to choose from.
