"At the median owner-occupancy rate zip code, we find that a 1% increase in Airbnb listings leads to a 0.018% increase in rents and a 0.026% increase in house prices."
Clicks on "actual research," finds the usual econometric voodoo. Even better, the use of instrumental variables to supposedly "isolate" effects. Totally representative, I am sure.
PS: the author's own words contradict your claim that the effect is tiny, although again I think this is a serious undercount resulting from a poor model and ever worse availability of data nationwide:
"This means that, in aggregate, the growth in home-sharing through Airbnb contributes to about one-fifth of the average annual increase in U.S. rents and about one-seventh of the average annual increase in U.S. housing prices."
