The sheer volume of migrant remittances to relatively poor countries, including those of Latin America and the Caribbean, nicely dramatizes the genuinely transnational social ties created by long‐distance migration. The evidence underlines that migration flows are serious business, not only for the individuals and families involved, but also for whole national economies. Thinking about remittances also allows us to identify some crucial social processes of which most migrants and first‐hand students of migration are well aware, but for which we have neither well‐established theories, carefully crafted concepts, nor extensive evidence. I mean the creation, use, and transformation of interpersonal trust networks within migration streams.
