When does Social Capital Matter for Migration? A Study of Networks, Brokers, and Migrants in Nepal.

The study of social capital has been one of the strongest areas of recent advance in migration research, but there are still many questions about how it works and why it has varying effects in studies of different places. In this article, we address the contextual variation in social capital's effects on migration by considering migration brokers. We argue that destinations for which migration is logistically difficult to arrange give rise to brokerage industries and hypothesize that brokers in turn substitute for the informational capital typically provided by social networks. Our empirical tests in Nepal support this narrative, showing that social networks matter for migration to destinations where brokers are not available and have little discernible effect on migration to brokered destinations. Our results suggest that migration research should consider the growing role of brokerage agencies, that theorizations of social capital more broadly must contend with how it is delimited by brokers, and that social scientists might also consider other consequences that can arise from these migration brokers that are increasingly common in many countries and provide a marketized replacement for social capital in some cases.
