The current state of academic research into peer-to-peer accommodation platforms

•The “sharing” phenomenon is the hottest trend in the hospitality and tourism industry.•The literature review identifies eight topics related to P2P AP.•Four topics define the business constituent elements of the SE, three are related to the impacts, one develops a holistic approach.•A research agenda has been developed, considering the general trends and research opportunities for the eight topics. The “sharing” phenomenon represents one of the hottest trends in the hotel and tourism industry. As the number of academic papers in this field is growing, now appears to be an appropriate time to take stock of the research. This article contributes to filling this gap by illustrating the state of peer-to-peer accommodation platforms (P2P APs) and identifying useful future research avenues. The paper is structured around two research questions: What is the state of the literature investigating P2P APs? What are some promising future research areas concerning P2P APs? This study proposes eight topics, while the literature review includes 189 published papers. After classifying the findings, this paper presents and discusses some pitfalls, as well as suggests implications for future research, while it also outlines specific research opportunities that are particularly suited for each of the eight topics.
