Geographical mobility in Europe is a chance and a challenge for regional labour markets. There is an unknown potential for the economy as foreign labour markets may provide qualified workers and the freedom of movement brings more flexibility. On the other hand, national and regional politics face the challenge of developing systematic approaches for enhancing mobility and managing its consequences. Transparency of migration flows, a sound database and substantiated knowledge about geographical mobility is the prerequisite for all actors. Therefore this anthology provides a synopsis of the current state of the art from different countries and regions, including best practice examples and solution approaches.
