Theoretical considerations suggest that secrecy reduces spillovers almost completely through non-disclosure, while the disclosure requirement of patents generates some spillover and at the same time allows firms to appropriate knowledge. In this paper we empirically analyze whether protection by...

We examine the relationship between fragmented intellectual property (IP) rights and the innovative performance of firms, taking into consideration the role played by in-licensing of IP. We find that firms facing more fragmented IP landscapes have a higher probability of in-licensing. For firms...

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...

The theoretical discussion concerning the question whether the incumbent or the (potential) entrant invests more into R&D has attracted considerable interest. This paper reports the results of an empirical study on this question using data of about 3500 German firms over the years 1992 to 1995....

This paper introduces a second, vertically related industry into the usual one-industry oligopoly framework of cooperative R&D investment between firms operating on the same product market. R&D efforts are affected by intra- and inter-industry R&D spillovers. Horizontal and vertical R&D...

This paper examines empirically the relationship between innovation and market structure within a simultaneous framework at the industry level of aggregation. We use a model in which R&D affects both, demand and cost conditions. An optimization process leads to optimal industry R&D expenditure...

Die Corona-Pandemie und die damit einhergehenden Einschränkungen in fast allen gesellschaftlichen und wirtschaftlichen Bereichen beeinflussen seit einigen Wochen das Leben der Menschen weltweit. Neben der möglichen Strategie, eine Herdenimmunität durch Infizierung von 60 bis 70 Prozent der...

This paper examines empirically the relationship between innovation and market structure within a simultaneous framework at the industry level of aggregation. We use a model in which R&D affects both, demand and cost conditions. An optimization process leads to optimal industry R&D expenditure...

This paper provides insights into the behavior of academic patentees who choose to bypass in-house Technology Transfer Offices (TTOs). TTOs have gained favor in recent years as academic institutions have tried to increase commercialization of their inventions. Using a large sample of researchers...

Introducing the concept of innovation capital we will analyse conditions under which a national industry is able to succeed in international Schumpeterian competition. Then we will discuss the significance of this concept for the economic development of the German plastics industry from the...
