This bit: > We find evidence that increases in Airbnb listings–but not reviews–led to more violence in neighborhoods in later years. Has me hypothesizing that an increase in listings but not in reviews means an excess of offer. This could be an early indicator of local socioeconomic degradation that ends up with increase in violence as late-stage symptom. The exodus of the well-off (and the listings that they leave behind) could be the missing link to investigate in further studies. One way to test this would be to contrast with the change in property sales and rentals. Some of those who are leaving ought to be selling or renting instead of listing on Airbnb. If only Airbnb listings are going up, then my hypothesis would most likely be false. > neighborhoods which are more violent for some other reason are more likely to end up as Airbnbs This doesn't look to be the case for me because there's a time interval between those. First the Airbnb shows up, years later comes the violence.
