This paper studies the links between productivity, innovation and research at the firm level. We introduce three new features: (i) A structural model that explains productivity by innovation output, and innovation output by research investment: (ii) New data on French manufacturing firms,...

Patent citations have been widely used in order to study inter-technology and science-technology relations. The present work aims at: i) exploring time relations and distance between technical/innovative activities and scientific knowledge, using journal articles citations in patents as a proxy;...

The purpose of this study is to investigate the copyright protection of intellectual property under vertical relations. Vertical relations among author, manufacturer and retailer are considered.

Die Rolle von Normen innerhalb des Innovationssystems ist sehr umstritten. Es wird sogar vermutet, dass die Zeit der Normung bereits abgelaufen sei. Andererseits wird von einer erstarrenden Regelsetzung gesprochen, die die notwendige Flexibilität für Erfindungen und Innovationen verhindere....

This paper uses a gravity framework to investigate the effects of distance as well as subnational and national borders in knowledge spillovers. Drawing on the NBER Patent Citations Database, we examine patent citations data at metropolitan level within the U.S. and the 38 largest patent-cited...

This paper analyses the nature of knowledge spillovers from research and development (R&D) in the field of liquid crystal display technology by estimating the impact of inventors' changing organizational and collaborative affiliations on the probability of citations in US patents filed between...

This paper aims to establish how the innovative activity in Finland has changed over time in the transition from a resource-driven economy to a knowledge-driven economy. The paper first takes a historical perspective on innovation and industrial activity in Finland through a descriptive...

This policy paper on science-industry technology transfer has four emphases: the rationale of recent changes in German science policy, the contribution of diverse transfer channels to economic development as well as the role of IPR in that context, the differences in the institutional framework...
