Abstract
Explores how transstate groups and associations interact with states and markets in migrant-induced flows of financial remittances, knowledge, political ideas and interests across state borders. Discusses if and how migrant organizations and groups have been complementary or incompatible with state and market principles, using the examples of small kinship groups, village associations, networks of businesspersons, epistemic communities, and diasporas. Touches on the implications for further research and argues that the concept of transstate social spaces, that is, spaces "in between" the local and the global, but also between states, can be used as an instrument to shed light on the dilemmas of border-crossing democracy and citizenship.
