This book deconstructs the 'sharing' marketing narratives surrounding Airbnb and similar platforms. It provides a conceptual analysis of the 'sharing economy' and accommodation sector and furthers the ongoing discussion surrounding Airbnb and the social sustainability of city tourism. The volume analyses the touristification of neighbourhoods in the context of broader economic and ideological shifts, thus bridging the gap between academic and social debate. It presents four different city scenarios of potential future developments and evaluates the effects of different regulatory responses, giving readers an understanding of the forces and factors at work and envisioning the ultimate consequences of current developments. The book will appeal to students and researchers in tourism and hospitality studies, futures studies and urban planning, as well as to policymakers and strategists in the hospitality and tourism sectors.
