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,...

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...

This paper investigates the role that pre-immigration skills play in immigrants job-finding processes in Germany. We first show theoretically that the job-finding rate for the high-skilled varies depending on their search strategy: if they are prepared to look for both unskilled as well as...

This paper analyses the effects of education signals for Ethnic Germans and Germans without a migration background ('Native Germans'). We base our analysis on a sorting model with productivity enhancing effects of education. We compare whether the signalling value differs between the migrants...

While many studies estimated the effects of active labour market programmes (ALMPs) on the participants' labour market outcomes, much fewer studies are concerned with effects of these policies on the regional matching-process between job seekers and vacancies. An essential part of many reforms...

This paper develops an extended version of the quality-ladder model by allowing for heterogeneous markets. Based on this model, it presents an empirical analysis of innovation-based growth at the market level using a technometric measurement concept. It can be shown that a growth-promoting...

Die präsentierte Studie untersuchte Bestimmungsgründe der F&E-Tätigkeit von deutschen Industrieunternehmen im Zeitraum von 1992 bis 2000. Die modelltheoretischen Analysen dienten dazu, testbare Hypothesen über wesentliche Einflussfaktoren und deren Wirkungsrichtungen auf die F&E-Aktivitäten...

Based on an extended game-theoretic innovation-race model, we derive some Schumpeterian hypotheses of the impact of technological rivalry, market power, technological opportunities and market size on the timing of product and process innovations. Using innovation data at the firm level in the...
