Airbnb 'has driven up long-term rental prices in New York by 1.4%'

"The new study, conducted by McGill Urban Planning professor David Wachsmuth, offers some pretty striking data points. While its analyses were conducted independently, the study itself was commissioned by the Hotel Trades Council and the AFL-CIO, two entities with a vested interest in keeping hotel business booming, so bear that in mind.
For starters, the study estimates that Airbnb has driven up long-term rental prices by 1.4 percent, or $384 per year, for the median New York City renter. The research suggests that both restricted availability in the long-term rental market and increased financial incentives in the short-term rental market account for this increase.
To reach those conclusions, the study drew from a comparative model developed by UCLA to rule out confounding variables that, specific to New York, might be driving those increases."
