We estimate the effects of R&D on firms' credit ratings and on financial distress. The main purpose is the comparison of firms in Western Germany and Eastern Germany as a transitional economy. Innovative activity has a positive impact on firm value proxied by ratings in Western Germany, but a...

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...

We estimate the determinants of various types of product innovation. Knowledge spillovers from rivals have a positive impact on incremental innovations. This impact is largely independent of the participation in R&D cooperations. Spillovers exert no such independent influence on drastic...

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...

Knowledge spillovers to competitors are regarded as an important aspect of the innovation process. While a company possibly benefits from incoming information on successful R&D conducted by other companies, a generally high probability of leakage of knowledge in an industry will negatively...

Wir diskutieren die Faktoren für eine erfolgreiche Umsetzung eines Systems des betrieblichen Vorschlagswesens und anderer Maßnahmen zur Stimulierung des Innovationserfolgs. Im Anschluss wird die Wirkung des betrieblichen Vorschlagswesens auf den Innovationserfolg empirisch überprüft. Als...

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...

Do financial market analysts use structural economic models when forecasting exchange rates? This is the leading question analysed in this paper. In contrast to other studies we use expectations data instead of observable variables. Therefore we analyse the implicit structural models forecasters...

The theoretical discussion concerning the question whether the incumbent or the (potential) entrant invests more into R&D has attracted considerable interest. This paper reports the results of an empirical study on this question using data of about 3500 German firms over the years 1992 to 1995....
