Das Papier analysiert die Auswirkungen von Signalen über das erreichte Bildungsniveau von (Spät-)Aussiedlern und 'übrigen Deutschen'. Die Analyse beruht auf der Sorting-Theorie mit produktivitätserhöhenden Effekten der Bildung. Aus dieser theoretischen Analyse folgen vier Hypothesen,...

Based on the factor price frontier, we investigate the effects of supply shocks ort labour markets in open economies. Two different supply shocks are considered: an oil price shock, and the integration of relatively labour-abundant countries into the world economy. With flexible wages, a...

Active labour-market policy (ALMP) not only affects the labour-market success of participants. Due to indirect effects, they might also affect the job perspectives of non-participants. Hence, even if ALMP programmes have a positive effect for the participants, this does not mean that ALMP...
