The Working Unit Migration deals with questions concerning the development of competencies and educational trajectories of migrants. The main focus is on the question to what extent migrants and their descendants systematically differ from the native population—for example, in terms of their acquisition of competencies, educational decisions, or returns to education. Furthermore, the team examines whether migration-specific aspects, such as particularly high educational aspirations, competencies in the language of origin, or ethnic discrimination can contribute to the explanation of ethnic educational inequality.
