Sommario/riassunto |
|
This book investigates the long-term impact of migration on development, engaging in a thorough analysis of the pertinent factors in migration. Migration scholars and stakeholders have long placed emphasis on the necessity of migration for development. At the heart of this book is the question: Has migration made development necessary, or is it the other way around? While existing literature is predominantly occupied with positive impressions about the migration-development nexus, this book challenges associated pervasive generalizations about the impact of migration, indicating that migration has not impacted all regions equally. This volume thus grapples with the different extents to which migration has impacted |

|
development by delving into the social costs that migrants often pay in the long run. With empirical support, this book proffers that some countries are becoming over-dependent on migration. A excellent resource for both policymakers working on migration policy, and scholars in international relations, migration and development studies, this book presents a range of innovative ideas in relation to the remittance-development nexus. . |
