I was speaking with our lawyer in Park City this week, and he commented to me that he wouldn't be going into the office next week because Old Town would be too hectic with the Sundance Film Festival going on. His office is right on Main Street.
When small mountain towns host major international events, there are going to be spillover effects. This is true of Sundance in Park City (population ~8,500) and it is true of the World Economic Forum, which was hosted in Davos (population ~10,000) this past week.
Perhaps the most obvious impact is that people can rent out their homes for large sums of money. And so lots of people both do that and try to profit maximize while doing it. Here are some anecdotes from Davos (via NZZ):
Ten days before the WEF, there are still 25 listings on the Airbnb internet platform. The prices here range from 8,000 to 56,000 Swiss francs. The son of an apartment owner says that his family receives 12,000 francs a week for their three-room apartment, which is quite close to the convention center. However, he says he assumes that they could achieve significantly more. The family rents out the apartment through an intermediary.
