Over the last two decades privatization programs in different countries radically reduced the role of the State as a key player in the economic arena. We use agency theory to discuss the theoretical relationship between changes in the firm's principal-agent structure following privatization, and...

Kleine und mittlere Unternehmen greifen zum Schutz von Innovationsergebnissen deutlich seltener auf geistige Eigentumsrechte zurück als größere Unternehmen. Der zurückhaltende Umgang mit Patenten, Urheberrechten oder Handelsmarken lässt sich in vielen Fällen durch den unternehmerischen...

We formulate a simple model of optimal defensive disclosure by a monopolist facinguncertain antitrust enforcement and test its implications using unique data on defensivedisclosures and patents by IBM during 1955-1989. Our results indicate that strongerantitrust enforcement leads to more...

This paper investigates the relationships between firm organization attributes, namely a structure á la Chandler, and their inward looking or exploitation attitude in R&D and innovation. We argue that because of sunk costs and learning processes an inward looking behavior is a consequence of...

By using the PatVal-EU dataset we find that the most important determinant of patent licensing is firm size. Patent breadth, value, protection, and other factors suggested by the literature also have an impact, but not as important. In addition, most of these factors affect the willingness to...

Our contribution to the expanding literature on the globalization of research and innovation is to investigate the extent to which sector-specific developments in an emerging technology (such as increasing interdisciplinarity and complexity) affect inventive activities developed abroad. We look...

Innovators who have developed advanced technologies, along with launching new products by themselves, often license these technologies to their rivals. When a firm launches a new product, product positioning is also an important matter. Using a standard linear city model with two firms, we...

An innovative firm with private information about its indivisible process innovation chooses strategically whether to apply for a patent with probabilistic validity or rely on secrecy. By doing so, the firm manages its rivals' beliefs about the size of the innovation, and affects the incentives...

A key issue of dfferent streams of economic literature is to determine the impact of certain dimensions of proximity on the cooperative behavior of actors and, thus, on interactive learning processes. This paper is a quantitative study on the impact of technological and geographical proximity on...

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...
