Do migrant social networks shape political attitudes and behavior at home?

Funding sponsor: Princeton University and International Growth CentreWhat is the role of international migrants and, more specifically, of migrant networks in shaping political attitudes and behavior in migrant sending countries? We propose that migration might change social norms for political participation, while it may also improve knowledge about better quality political institutions. Hence, international migration might increase political awareness and participation both by migrants and by other individuals in their networks. To test this hypothesis, we use detailed data on different types of migrant networks, namely geographic, kinship and chatting networks, as well as several different measures of political participation and electoral knowledge – namely, self-reports, behavioral and actual voting measures. These data were purposely collected around the time of the 2009 elections in Mozambique, a country with substantial emigration to neighboring countries and with one of the lowest political participation rates in the southern Africa region. The empirical results show that the number of migrants an individual is in close contact through regular chatting within a village significantly increases political participation of residents in that village – more so than family links to migrants. Our findings are consistent with both improved knowledge about political processes, and increased intrinsic motivation for political participation being transmitted through migrant networks. These results are robust to controlling for self-selection into migration as well as endogenous network formation. Our work is potentially relevant for the many contexts of South-South migration where both countries of origin and destination are imperfect political systems. It shows that even in this context there may be domestic gains arising from international emigration.authorsversionpublishe
