An instantiation of the sharing economy marked the emergence of an ad hoc governance
structure, including joint efforts from the public sector, NGOs, private firms, civil society,
and migrant organizations. On one hand, such an ad hoc governance structure built on
challenging organizational legitimacy and inventing new co-creation tools may contribute to
reducing the disconnections between interventions by governance actors and migrants’
experiences, situations, and actual needs. On the other hand, the complexity of multilevel
governance systems and collaborations can also generate greater uncertainty about migrant
integration processes. This special issue involves articles that contribute knowledge to how
collective action is enabled in a sharing economy in support of precarious migrants in a
diversity of contexts and situations. This collection includes articles examining voluntary
contribution to migration management and care at all different levels, from the public sector
organizations to private firms, to civil society and migrant-led initiatives and networks.
