This policy brief, which concludes a nine-brief series examining what is known about the linkages between migration and development, suggests that the policy framework on migration and development remains relatively weak, and few development agencies have made it a priority to promote the positive impact of international migration.

Circular migration has typically been viewed with skepticism by migrant-rights advocates and wary publics alike. But many experts and policymakers in the migration field — and some in development — have come to recognize that well-managed circulation that is respectful of migrants' human and labor rights can bring benefits to countries of origin and destination, as well as to migrants themselves. For countries of origin, circular migration can relieve labor surpluses; for destination countries, it can provide the flexibility to quickly overcome skills shortages while adapting to long-term labor market shifts. For migrants, circular migration offers the opportunity to earn higher wages and gain international experience.

Diasporas can play an important role in the economic development of their countries of origin or ancestry. Beyond their well-known role as senders of remittances, diasporas also can promote trade and foreign direct investment, create businesses, spur entrepreneurship, and transfer new knowledge and skills. Policymakers increasingly recognize that an engaged diaspora can be an asset — or even a counterweight to the emigration of skilled and talented migrants.
