This report highlight is based on the Least Developed Countries Report series. It explores the ‘push and pull’ forces that contribute to the international migration of skilled persons from least developed countries (LDCs), and how outmigration continues to reduce the potential of Least Developed Countries for technological catch-up and absorptive capacity. The report highlights how national policies in the countries of origin and destination countries, as well as  international cooperation and networks with diaspora, can limit the damage from such migration and derive gains from it. It also explores the potential of remittances to stimulate consumption and investments in the receiving countries.
