This document summarizes a presentation on assessing the costs and benefits of labor migration for sending and receiving countries. It discusses how migration can create unemployment in sending countries by reducing the supply of skilled labor, but also how remittances sent back by migrant workers provide benefits. Both sending and receiving countries can gain advantages from migration, such as filling labor needs, but the costs for sending countries may outweigh the benefits as they see little return on their investment in educating migrant workers. Policy initiatives are needed to better share the gains of migration between countries.
