My apologies for not keeping you up to speed on events in Saskatoon, where the city has been considering building a new downtown arena, at a potential price tag of $375 million plus land costs, to replace the 30-year-old SaskTel Centre. That’s been going on for a few months; I mention it now because University of Michigan sports economist Mark Rosentraub is in town (in Saskatoon, I mean, not in my town or yours, unless you live in Saskatoon) to give a talk about building a new downtown arena, and how totally awesome it would be:

“Sport venues have been very, very successful,” said Mark Rosentraub, professor of sports management at the University of Michigan… “There is no city where we have not been able to literally put something together something where the public sector gains and the private sector gains,” he told CBC Radio’s Saskatoon Morning.

Setting aside Rosentraub’s odd syntax — it’s a transcribed radio interview, I’ll cut him some slack — you may be forgiven for wondering, What, what the hell is he on about? Isn’t this entire website a 20-year record of cities that have not been able to put together something where the public and private sectors both gain?

Rosentraub has long been an odd duck in the sports stadium world. Way back in 1997, he wrote a book called Major League Losers, which, as you can probably guess from the title, talked about private sports stadiums as bad deals for cities. Since then, though, he’s been more sunny on the prospect, noting that building venues downtown can move economic activity to the city center — true, if your only concern is where people spend their money and not how much they spend in your metro area overall. It will be left as an exercise for readers to determine whether this change of message is related to Rosentraub’s side business of working as a consultant for cities and teams that want to build downtown stadiums and arenas.

Anyway, building a new arena isn’t an inherently terrible idea, if the city will own it and get any increased revenues from it, and — crucially — if those new revenues will be enough to make it worth the $400 million-ish price tag. The only sports tenants are the minor-league junior hockey Saskatoon Blades and the National Lacrosse League team the Saskatchewan Rush, so this deal would have to pencil out based on being able to draw more concerts to town. Could Saskatoon make an extra $25-30 million a year just by offering more concession stands and restrooms? That’s the interesting and important question that needs to be asked, rather than nattering about how an arena can “anchor” an “entertainment district.” I can recommend several sports economists, or even arena managers, who could begin to address that question, if anyone in Saskatoon is interested.
