Better understanding the innovative process of renewable energy technologies is important for tackling climate change. Though concentrating solar power is receiving growing interest, innovation studies so far have explored innovative activity in solar technologies in general, ignoring the major differences between solar photovoltaic and solar thermal technologies. This study relies on patent data to ...

This paper studies technological change in renewable energies, providing empirical evidence on the determinants of innovative activity with a special emphasis on the role of knowledge spillovers. We investigate two major renewable energy technologies - wind and solar - across a panel of 21 OECD countries over the period 1978 to 2004. Spillovers may occur at the national level, either within the same ...

This paper investigates whether and to what extent the acquisition of external disembodied technology affects the efficiency and productivity in innovation of technology acquiring firms. Using the stochastic frontier analysis combined with a difference-in-difference ...

Germany has profited from the internationalization of research and development (R&D) in multinational companies. While the international R&D balance sheet was balanced until 2001, foreign companies now invest more in R&D in Germany than German companies abroad. The share of R&D expenditures of German multinationals abroad is declining, whereas their global expenditures are increasing. This means the ...

In recent decades the internationalization of small and medium-sized enterprises (SMEs) has increased significantly, especially in manufacturing industries. Yet in contrast to large, multinational corporations, not much is known about the international activities of SMEs. Data on East German SMEs show that size and innovative capacity have a significant influence on a company's international involvement, ...

The paper investigates the link between bank concentration and a country's buyout market. We perform a macro level analysis for 15 European countries during 1997-2007. We estimate the elasticity of the country i's buyout market to country i's concentration in the banking sector. Our major finding suggests that the more concentrated the banking sector is, the better it is for the size of the buyout ...

What kind of smart capital relational investors actually supply, especially in a bank-based financial system such as the German one, is still an open question. We divide smart capital into single components and conduct a survey with 85 German suppliers of start-up finance. The results show that the degree of 'smartness' is determined by the financial product used and partly also by the financiers' ...
