'Migration has often been ignored in international political economy, and Leblang and Helms provide a terrific corrective to this blind spot. Tracing the migration process from the decision to leave through where to go and whether to send back remittances, they convincingly show that politics-not just economic or social factors-affects every step in the migration process. Leblang and Helms then turn from explaining the migration process to demonstrating that migrants are the glue that helps hold global finance together. This book is a must-read not only for migration scholars but for all those interested in the global economy.' Margaret Peters, UCLA
