Peer-to-peer-accommodation, a sharing economy-based business model, enables using unutilized houses, apartments, and rooms of individuals to provide shared accommodation to tourists and travelers. On account of the importance of peer-to-peer accommodation, many studies have been conducted on factors/stimuli driving peer-to-peer accommodation adoption; however, findings remain inconsistent and fragmented. Accordingly, using the stimulus-organism-response model, this meta-analysis provides generalized findings on determinants driving peer-to-peer accommodation adoption. Our meta-analysis shows that stimuli (service characteristics, psychological aspects, social aspects, and technological aspects) drive the organism (perceived service quality) which in turn drives peer-to-peer accommodation adoption. Further, our moderation analysis shows that the relationship between these stimuli and the organism, and the relationship between the organism and peer-to-peer accommodation adoption, vary depending on four moderators: sample type, country of study, survey administration method, and sample size. Overall, this study contributes to the stimulus-organism-response theory by extending it to the meta-analytical approach and suggesting a new organism for inclusion in the original stimulus-organism-response model. This meta-analysis also contributes to the peer-to-peer accommodation and sharing economy literature and provides practical recommendations for accommodation platform providers and their listed houses to develop marketing strategy and policy.
