The sharing economy is anchored to two opposite logics: sharing and market exchange. This results in tensions between a pro-social orientation and communal norms on the one hand (i.e. solidarity, mutuality, generalized reciprocity and communal belonging) and a for-profit orientation and market norms on the other hand (i.e. profit maximization, self-interest and utilitarian motives). This article aims to distinguish among the different practices and phenomena related to the sharing economy, focusing on the tensions emanating from renting private possessions through collaborative consumption platforms.
