Airbnb Predominance Index: the platform’s influence on the Brazilian rental market

Abstract This article proposes a statistical methodology to assess the impact of Airbnb on the long-term rental market in Brazilian municipalities. Recognizing disruptions in what was initially celebrated as the sharing economy, the study situates Airbnb in the context of platform urbanism and analyzes its repercussions. Rio de Janeiro was chosen as the case study due to its large number of listings on the platform and its established rental market. The proposed index considered variables such as the number of listings, types of properties, population data, households, and neighborhood area. The study concluded, based on the variability of the index, that Airbnb's influence on Rio de Janeiro's rental market is greater in neighborhoods with high tourist attractiveness.
