An adequate supply of highly quali ed workers is a central prerequisite for the ability of peripheral and economically lagging regions to develop. In order to take advantage of endogenous potential, bottlenecks in human knowledge and know-how must be overcome by means of support from outside. An important element in this is migration. Taking as an example the Weser-Ems region in northwestern Germany, the strategies used by local enterprises to motivate managerial staff to move from other regions are shown and the level of success achieved is described. As is shown, the regional labour market has lost signi cance for the upper segment in the course of structural changes in the economy, which has led to an increase in the necessity for cross-regional searches in order to ll managerial posts. As enterprises in peripheral locations have poor starting conditions in the cross-regional competition for highly quali ed workers, this development demands that more and more enterprises mobilize considerable resources for the recruitment of staff. Although the ndings indicate that the potential of workers willing to migrate is greater and more diverse than is often assumed, they also show that certain types of enterprises have great dif culty in overcoming independently the personnel-related disadvantages resulting from the location, and require support through regional structural policy.Ruth Rohr-Zänker, IES, University of Hannover, Lister Strasse 15, 30163 Hannover.
