Amsterdam has a higher ratio of tourists to residents than Florence, Italy, the researchers report. The number of overnight visitor stays reached almost 16 million in 2017, up from 8 million in 2008. Meanwhile, the short-term rental market—80 percent of it on the Airbnb platform—was nonexistent in 2008 but later surged to more than one of every 20 rental units citywide. In some central neighborhoods, the ratio was one out of five.
The researchers calculate that as tourism and Airbnb offerings rose, so did housing costs, but some residents gained a net benefit from the amenities that tourism attracted. For single people and young families, the new amenities offset the increase in housing prices. Older families, meanwhile, tended to leave neighborhoods heavily influenced by tourism, and the researchers inferred that they moved at least in part because they didn’t care for the new businesses.
This demographic movement can reduce urban inequality, they suggest, since “location sorting”—people migrating to neighborhoods with amenities they value—lessens pressure on housing inventory and rental prices.
In this way, the mutually reinforcing presence of tourism and touristic amenities can serve as a progressive tax, the researchers write. In their model, wealthier older families show an average welfare loss equivalent to a 5 percent income tax. Rents go up, and the commercial dimensions of the neighborhood serve them worse. Younger families and single people, on the other hand, show welfare gains of 1–3 percent of their income, the researchers find.
The model’s nuanced evaluation of amenities allows for a look at different approaches to regulating tourism. Almagro and Domínguez-Iino considered the difference between taxing short-term rentals and taxing touristic amenities. They find that taxing short-term rentals benefits all residents—older and younger families along with individuals—since housing costs don’t rise as rapidly when fewer short-term rentals enter the market.
But taxing touristic amenities hurts younger families and singles, two groups that benefit from the amenities’ entry into a neighborhood.
“Our paper opens up this box of understanding,” Almagro says. “Heterogeneity matters when it comes to how people choose where to live in a city and what benefits they get from those choices.”
