Recent research interest has focused on the impact of the room sharing business model on housing markets. However, existing empirical evidence is limited and exclusively focuses on few large cities in the U.S. This study examines the effects of Airbnb on housing rental and sales prices using a unique large-scale dataset comprised of housing market transaction records and the number of Airbnb listings drawn from their website in Taiwan. We estimate a fixed effect model of housing rental and sales price equations and find that a one-standard deviation increase in the number of Airbnb listings raises house rental prices by 0.38%. This finding suggests that a substitution effect is present between Airbnb's short-term accommodation and the housing rental market. Moreover, a larger effect on rental price is found among Airbnb listings that offer an entire room or apartment. Additionally, since September 2017, multinational digital platform companies must comply with a new sales tax policy in Taiwan. We evaluate the effect of this tax policy using the difference-in-difference method and find a negative impact on the number of Airbnb listings and housing rental prices after its implementation. This study is the first to empirically assess the effectiveness of tax policy on regulating room sharing business models.

This thesis explores the role of owner-occupied apartments (ägarlägenheter) in the Swedish private rental market, particularly in light of the government’s legislative proposal SOU 2024:83 “More Paths to Owning Your Home”. The proposal aims to simplify and promote the formation of owner-occupied apartments by enabling conversions of existing rental units and removing the requirement for a minimum of three units. If implemented, these changes could significantly alter the structure of the Swedish housing market, especially concerning private rental practices. The study employs a legal-analytical methodology to examine Swedish property law, tenancy regulations, and relevant legal doctrine. A key focus is the comparison between condominiums and owner-occupied apartments, particularly in terms of legal requirements for private rental. Unlike condominium owners, owner-occupiers do not need approval from a housing association to rent out their private home, granting them greater autonomy but also raising concerns about social control and residential security. The study highlights that a broader implementation of owner-occupied apartments may increase short-term renting via platforms such as Airbnb. Prior research suggests that this could contribute to gentrification, rising property prices, and a reduction in long-term rental housing, particularly in central urban areas. At the same time, the model may improve housing market flexibility and promote mobility, especially in growing c

population, largely attributed to the influence of Airbnb causing investors to purchase apartments to use as short-term rentals. Following the COVID-19 pandemic Beginning in April 2024, there have been protests in Spain against overtourism, specifically in the archipelagos of the Balearics and Canaries, and in the mainland cities of Barcelona, San Sebastián and Málaga. These first three locations are the top three most-visited in Spain by tourists. Following the COVID-19 pandemic limiting tourists' opportunities to travel, the numbers of visitors to Spani Barcelona in particular is a city that has suffered from overtourism for many years. Concerns became elevated in 2018 and 2019, directed at both beach and cultural tourism, with protests and anti-tourist graffiti. Between 2007 and 2019, some areas of the city experienced a 45% decrease in resident population, largely attributed to the influence of Airbnb causing investors to purchase apartments to use as short-term rentals. Following the COVID-19 pandemic preventing tourists from travelling, many popular tourist destinations have seen a surge in tourism and record visitor numbers as tourists return in large numbers all at once. In April 2020, a proposal for radical change in the organisation of the city, the "Manifesto for the Reorganisation of the city after COVID-19", was published in Barcelona by architecture theorist Massimo Paolini and signed by 160 academics and 300 architects. The manifesto is radically critical towards the touristification and commodification of the city, proposing to: "eliminate cruise ships", "maintain the current dimensions of the airport", "stimulate touristic degrowth", and "eliminate any investment to promote the 'Barcelona brand'". In August 2021, Barcelona became the first city to ban short-term private room rentals. Space is naturally limited on islands, with a growth in tourism – and the related renting of properties to tourists at inflated rates – has caused a housing crisis. By 2024, about 1,000 residents of Mallorca lived in their vehicles, as did an unspecified number of Ibiza residents. The government of the Balearic Islands since 2023 is conservative, and refused to implement the rent cap introduced by the Spanish government. In March 2024, the Balearics government began imposing severe fines for anti-social behaviour from tourists, bringing the restrictions in line with the laws on residents, as the number of tourists continued to grow and such incidents increased. In the Canary Islands in 2023, a third of residents were at risk of poverty. Since being designated European Capital of Culture in 2016, San Sebastián has experienced an accelerated process of touristification, which has had a particularly significant impact…
