The surge in interfirm cooperative agreements can be seen as expressing a way for firms to respond to and to organize market failure, especially in technology markets. The incentives of firms to internalize activities are to avoid the disadvantages, or capitalize on the advantages, of...

In diesem Beitrag wird ein Oligopolmodell der Innovationsaktivität entwickelt und mit Daten aus dem Mannheimer Innovationspanel geschätzt. Das Modell erlaubt es, bei der empirischen Umsetzung auf die Verwendung von Marktanteilsdaten und Nachfrageelastizitäten zu verzichten, die typischerweise...

Dieser Beitrag untersucht die Innovationsstrategien und Forschungs- und Entwicklungsaktivitäten (FuE) ostdeutscher Unternehmen sowie mögliche Innovationsdefizite in diesem Zusammenhang. Als Hinweis auf die zu geringen Innovationsaktivitäten ostdeutscher Unternehmen werden häufig die...

This paper develops a three stage oligopoly game for R&D cooperation, R&D expenditure and product market competition. In the first stage, firms decide whether or not to conduct R&D in cooperation with other firms. In the second stage the level of R&D investment is determined. Finally, firms...

This paper deals with the effects of publicly funded research at universities, polytechnics and federal research labs on industrial innovations in Germany. We discuss the characteristics of companies that benefit from the findings of public research institutions. In questioning 2,300 companies...

Innovation activities in the German enterprise sector showed two opposing trends over the past two decades: While total innovation expenditures grew substantially, the number of firms conducting innovation activities fell sharply.

China recently surpassed the USA as the greatest global source of patent applications. However, without internationally comparable measures of patent quality it remains questionable whether China's patent expansion constitutes the rise of a new technological superpower. Our novel quality index...

This study analyses the effectiveness of targeted public support for R&D investment. In particular, we test whether the specific policy design aiming at incentivizing (international) collaboration and R&D in small and mediumsized firms achieves the desired objectives on input as well as output...

R&D collaboration facilitates pooling of complementary skills, learning from the partner as well as sharing risks and costs. Research therefore repeatedly stressed the positive relationship between collaborative R&D and innovation performance. Fewer studies addressed potential drawbacks of...
