This volume is the result of an international research project that drew together perspectives from three countries in Central, Eastern, and South-Eastern Europe: Croatia, Lithuania, and Poland. It explores the under-researched phenomenon of immaterial values and resources that returning migrants bring with them, as they have the potential to contribute to economic development, together with the social, political, and cultural change in their countries of origin. The authors explore the mechanisms, challenges, and successes of the process of social remitting by returnees to these countries.
