We develop a composite indicator measuring the performance of national innovation systems. The indicator takes into account both "hard" factors that are quantifiable (such as R&D spending, number of patents) and "soft" factors like the assessment of preconditions for innovation by managers. We...

This paper discusses the impact of a firm's technology portfolio on its market value. Two concepts are used to characterize a firm's portfolio: the number of technological fields and the degree of relatedness within the portfolio characterized by the amount of joint occurrences of patents in...

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...

This paper analyzes research efficiency at the industry level in manufacturing for 13 European member and four nonmember countries during 2000 and 2004. A unique dataset was compiled that matches patent applications at the European Patent Office (EPO) to industry-specific R&D inputs from EU...

This paper assesses the relative efficiency of knowledge production in the OECD using a nonparametric DEA approach. In general, resources allocated to R&D are limited and therefore must be used efficiently, given the institutional and legal constraints. The efficiency scores presented are based...

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...

Das DIW Berlin hat in diesem Jahr zum fünften Mal im Auftrag der Deutschen Telekom Stiftung und des Bundesverbandes der Deutschen Industrie (BDI) einen Gesamtindikator für die Innovationsfähigkeit Deutschlands im internationalen Vergleich ermittelt. Dabei wird die Fähigkeit eines Landes,...

Die Lissabon-Agenda sieht eine Steigerung der Ausgaben für Forschung und Entwicklung bis zum Jahr 2010 auf drei Prozent des Bruttoinlandsprodukts vor. Europa will damit zu einem der wettbewerbsfähigsten und dynamischsten Wirtschaftsräume werden. Wesentlich für die Zukunftsfähigkeit eines...
