The debate was organized by the Housing Solutions Platform and hosted by MEPs Marian Harkin (ALDE) and Brando Benifei (S&D) in the European Parliament, to respond to the controversy on the impact of the sharing economy on housing affordability.

Why this event?

Short-term rental platforms (such as Airbnb, HomeAway and others) have developed over the past few years thanks to technological developments. Their impact on cities and communities is starting to be analyzed but remains disputed. The new business model, which enables private property owners to rent part or all of their apartments to guests, faces increasing controversy particularly as to its impact on housing prices. This Housing Solutions Platform debate proposed to gather cross sectoral actors and experts to discuss the claim and potential way forwards. Representatives from the P2P industry, academics, city representatives and European policy makers debated on the existing evidence and potential ways forwards in channeling the impact of the sharing economy on housing prices.

Not enough data, but evidence of a decisive impact in some urban areas

There is little empirical evidence about the impact of the sharing economy platforms on housing prices. First results from two pieces of research about the impact of the presence of Airbnb on prices and rents in the USA and in Barcelona were presented. Despite methodological challenges, which make their results fragile, both studies indicate a decisive contribution of short-term rentals in rents and housing prices. Davide Proserpio from the University of Southern California, presented the results of one of the major studies on the impact of AirBnB on housing prices in the US, based on an analysis of Airbnb dataset listings in the US over a six year period (2011-2016). The results of the study show that Airbnb increases both rental rates and housing prices. It would explain 0.59% of the annual increase in US rental rates and 0.82% of the annual increase in US housing prices.

Miquel-Àngel Garcia-López, Associate Professor Department of Applied Economics School of Economics and Business in Barcelona, presented the initial results of one of the first studies on this theme in Europe. It concluded similar effects, namely that a 1-point increase in Airbnb density would lead to increases in rents of 0.5 to 1% and increases in prices of 1 to 1.8% in Barcelona

The US study suggests the impact can be explained by the fact that a percentage of property owners remove their flats from the long-term rental market, expecting higher revenues from the short-term rentals market. They thereby contribute to a decrease in available housing and a subsequent rise in rent.

Participants welcomed these studies and agreed on the need for more research on this topic to allow empirical based policy-making. Representatives from the P2P industry insisted on their willingness to engage in the debate and called for proportional regulation adapted to opportunities offered by new technological development.

The way forward: evidence-based regulation adapted to fast changing technological developments

Several cities have started to introduce regulation of short-term rental activity. Indeed, AirBnb Public Policy and Campaign Manager Sergio Vinay informed attendees that Airbnb has made over 400 agreements with local and national governments across the globe. Representatives of local government have stressed the need to differentiate between professional and occasional use. In order to do so, regulations usually distinguish between primary and secondary homes. In some countries, like France or Germany, large cities have introduced limitations on the number of days a home can be subjected to short-term rental. Dublin City Council presented forthcoming legislation that will require property owners to seek planning permission before letting properties out short-term from June 2019. In Barcelona, the tourism strategy of the city implies differentiating regulation of tourist accommodation in different neighbourhoods, including a ban on new tourist accommodation in the city centre. In Amsterdam, the city has created a team to work on illegal short-term renting. In some places, short-term rental providers have started to collaborate with local authorities on regulation enforcement. This work needs to be continued, focusing on the general interest of the population rather than of the interest of some individuals.
