Public procurement has been at the centre of recent discussions on innovation policy on both European and national levels (e.g., Aho-Report, Barcelona Strategy). It has a large potential to stimulate innovation since it accounts for 16% of combined EU-15 GDP. We embed public procurement for...

We study the performance of conditional asset pricing models in explaining the German cross-section of stock returns. Our test assets are portfolios sorted by size and book-to-market as in the paper by Fama and French (1993). Our results show that the empirical performance of the Capital Asset...

Subsidising research networks has become a popular instrument in technology policies, driven mainly by expected positive spillovers. In particular, the stimulation of R&D co-operation between scientific institutions and industry is considered as most promising. In the context of policy...

This paper studies the impact of process and product innovations introduced by firms on employment growth in these firms. A simple model that relates employment growth to process innovations and to the growth of sales separately due to innovative and unchanged products is developed and estimated...

Im Zusammenhang mit den neuen "Basel-II"-Regelungen, die die Kreditvergabe an Unternehmen verändern, wächst das Interesse besonders kleiner und mittlerer Unternehmen an hybriden Finanzierungsinstrumenten. Diese Finanzierungsform wird auch als Mezzanine- Finanzierung bezeichnet. Je nach...

This study presents a novel empirical approach to identify financing constraints for innovation based on the idea of an ideal test as suggested by Hall (2008). Firms were offered a hypothetical payment and were asked to choose between alternatives of use. If they choose additional innovation...

This paper explores the role of R&D worker mobility on innovation performance. As one main novelty, we employ churning as a measure for worker mobility. Churning depicts the number of workers which are replaced by new ones. It is a very informative indicator since a firm may be exposed to...

The internationalisation of corporate R&D opens up the chances to participate in international knowledge sharing. This increasingly motivates firms to accelerate the pace and extent of their international R&D activities in order to enhance innovativeness and consequently competitiveness and...

There are noticeable differences between the roles that various forms of credit financing play in family businesses and in other businesses. Family businesses take out more often bank loans specifically to finance investments and innovations, and they particularly often resort to the short-term...

This paper presents and compares several time-series models for returns of broadbased stock indices. These models nest a nonlinear asymmetric GARCH (NGARCH) model as a special case. Some of these models are empirically motivated ad-hoc specifications others are derived from a representative...
