Book excerpt: The international mobility of talented individuals is a key part of globalization. In the quest to promote innovation and entrepreneurship, many governments have sought to attract skilled migrants from abroad, inciting both a global competition for talent and concerns about the displacement of domestic workers. This important new work investigates why skilled individuals migrate and how they shape innovation around the world. Using patent data from the World Intellectual Property Organization (WIPO), it charts patterns of high-skilled migration worldwide. In addition, contributions by leading migration scholars review the latest research insights, discuss new approaches to studying high-skilled migration and present fresh evidence on the causes and consequences of greater talent mobility. This book will prove invaluable to policymakers seeking to understand how migration policy choices affect innovation outcomes as well as academic researchers interested in the migration-innovation nexus.
