The bid for the 2022 Winter Olympics was awarded to Beijing after Stockholm and Krakow, Poland, withdrew their bids.
Why the reluctance to host the games?
Budgetary concerns remain the primary deterrent. Security costs alone can rack up to billions of dollars, not to mention the time and money that goes into planning the games and constructing massive infrastructure projects, including thousands of hotel rooms to accommodate athletes and guests.
The return, according to many major economists, doesn't nearly offset the cost.
"The games overrun with 100 percent consistency. No other type of mega project is this consistent regarding cost overrun," researchers from Oxford's Saïd Business School wrote in an academic paper in 2013. "Other project types are typically on budget from time to time, but not the Olympics."
