Today, more than 70% of the world's total electricity production is supplied by power plants using conventional fossil fuels. Coal accounts for more than half of the fossil fuel combustion in electricity plants. Future mega trends give reason to believe that electricity demand will double until...

In der Diskussion um Innovationen für eine nachhaltige Entwicklung werden häufig radikale Innovationen gefordert, damit die Transformation der Gesellschaft hin zu einem als nachhaltig empfundenen System gelingen kann. Begründet wird dies mit einer höheren Umwelteffizienz dieser Innovationen....

This paper investigates the impact of in-house R&D and innovation management practices on innovation success in small and medium-sized firms (SMEs). While there is little doubt about the significance of technology competence for generating successful innovations, inhouse R&D activities may be 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...

Energy and resource efficiency innovations (EREIs) are often seen as win-win opportunities for both the economic and the environmental performance of firms. It is thus worth asking how the innovation activities and performance of firms with regard to energy and resource efficiency look like: Do...

This paper analyses two aspects of environmental regulations triggered by ecoinnovations. First, whether there are long term effects of regulation on innovation. Second, whether the impact of different types of regulation differ by type of the environmental benefit of the innovations. To answer...

This paper analyses the relationship between past innovation output, competition, and future innovation input in a dynamic econometric setting. We distinguish two dimensions of competition that correspond to the concepts of product substitutability and entry barriers due to fixed costs. Based on...

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...
