The sharing economy refers to a collaborative economic model centered on the social sharing of goods and services. Characterized by decentralization and peer-to-peer relationships, this model often complements or replaces traditional hierarchical and competitive market strategies. Central to sharing economy activities is the use of digital technologies, which facilitate information exchange and support the production, funding, and exchange of goods and services. Since its popularization around 2012, notably through platforms like Airbnb and BlaBlaCar, the sharing economy has gained traction, especially in Europe. It promotes the efficient use of underutilized resources—such as tools or accommodation—by allowing temporary access in exchange for money or donations. This innovative model fosters trust among strangers through reputation systems, where online ratings influence users’ reliability perceptions. Ultimately, the sharing economy not only encourages resource reuse but also cultivates new social interactions beyond traditional networks, highlighting a shift toward collaborative consumption in the digital age.
