The analysis uses administrative as well as survey data. The results suggest that East Germans faced significant initial ...

The career mobility model suggests that overeducated workers are more prone to take up on-the-job training, to climb up the career ladder, or to leave to professions more suitable to their educational level.

Comparing adequately qualified and overqualified workers in jobs that require the same level of formal qualification ...

However, our analysis also suggests that certain effects differ between crafts and non-crafts, most notably the role of the Big Five ...
