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 ...
To quickly adapt to technological change and developments, and thus remain competitive, firms increasingly resort to the use of external technology. 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, ...
How do new and foreign firms achieve superior productivity? Do they conduct more and better R&D? Or do they distinguish themselves through computerization and organizational capital? We investigate the determinants of and returns to several types of investment, using a panel of over 40,000 Ukrainian industrial firms in 2000-2007. Foreign firms engage in more non-technological investment and IT and ...
On behalf of the Deutsche Telekom Stiftung (Deutsche Telekom Foundation) and the Bundesverband der Deutschen Industrien (Federation of German Industries) DIW Berlin has investigated Germany's innovative capacity for the fifth time in an international comparison. The survey evaluates the ability of countries to create and transform knowledge into marketable products and services (i.e., innovations) ...
