This book provides critical perspectives on contemporary collaborative consumption, a recent societal phenomenon shaking up previously fixed socio-economic categories such as the producer and the consumer. The contributors discuss the role of trust and reciprocity in collaborative consumption through seven case studies. The chapters advance debates on the contradictions of positioning collaborative consumption as possible solutions for a more sustainable development and exacerbating new forms of inequalities and injustice. The book contributes a nuanced appraisal of social and economic activity for reflecting socio-technological changes in contemporary societies.
