This course covers the economic aspects of recent trends in global migration flows. The course is targeted towards advanced Bachelor students, who want to expand their knowledge on the economic causes and effects of international migration and learn about the advances in recent migration research. The course approaches topics of migration economics from various perspectives: Why do people migrate? Who migrates? What are the labour market effects of migration? We will explore these questions by introducing basic economic concepts and by comparing model predictions with surprising insights from empirical migration research.
