Collaborative economy

Collaborative economy refers to marketplaces that provide access to goods, services or skills through Peer-to-Peer exchanges. NADI explores the economic, technological and societal/environmental impacts of such exchanges.



The sharing economy or collaborative society is a new paradigm developing very rapidly where using a good or a service prevails over its ownership. Such an access-based approach is supported by societal, economic and technological facilitators.

A report by PwC predicts that 5 key sharing sectors (P2P finance, online staffing, P2P accommodation, car sharing and music/video streaming) have the potential to increase global revenues from 15 billion USD in 2014 to 335 billion USD by 2025.

NADI investigates a series of issues related to this emerging collaborative economy/society, including the technical functioning of the P2P platforms enabling providers and users to share or exchange goods and services in a secure and privacy- aware way; the psychological processes (motivations, attitudes, emotions etc.) underlying the adoption of collaborative initiatives; the extent to which technical, informational and social competences are mobilized by users; the legal rules applied to users and platforms in the sharing economy (in particular, consumer protection, labour law, and competition law).
