Even when émigrés living abroad versus returning migrants share similar norms, knowledge, practices, and ideas with non-migrants living in their origin country, émigrés have a stronger influence on non-migrants' political beliefs and behaviors. The reason is that outmigration affects the social ties in which discussions between émigrés abroad and non-migrants are embedded, making them more cohesive and asymmetrical. In contrast, returning permanently to the origin country reverses these effects. © 2014 Springer Science+Business Media New York.
