The city put up millions in taxpayer funds to get the arena built for the local high-profile college basketball team, and numerous reports were published around the positive economic impact of the stadium, citing increased spending around downtown, etc.
However, the report failed to account for "micro" details that can have a major impact on local business, like traffic congestion, entertainment capacity, etc. On game days, his restaurant is overcrowded and turning away patrons, which negatively impacts his staff and quality of experience. But there are only 15 or so games per year, and the off-season attractions are hit-or-miss in terms of attendance. And when nothing is going on, business is even more varied.
It's relatively easy to calculate how many people come to town for a big event and how much they spend, extrapolating that out to some great figure, but a restaurant can't reasonably rely on ~15 big days per year. Quite often, economic impact reports are commissioned by folks who have business or political interests at stake, thereby overlooking the potential bottlenecks that such developments expose. And because most of the public doesn't understand finance or real estate, and yet they love the basketball team, a more nuanced conversation around the topic is harder to find.
