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...

Declining R&D intensities at the national level coincide with growing international technological links. Deviations of individual OECD countries from the average R&D intensity reflect differences in industry structure as well as in sectoral R&D intensity. At the same time, the sectoral...

Research Joint Ventures (RJVs) are projects that combine the research resources of different firms. A sample of RJVs supported by the U.S. Advanced Technology Program shows that the projects yield revenues that are far less than costs. Related to this point, the RJVs are subject to...

We reconsider the justifications of R&D subsidies by Spencer and Brander (1983) and others by allowing firms to pool R&D investments and license innovations. In equilibrium R&D joint ventures are formed and licensing occurs in a way that eliminates the strategic benefits of R&D investment in the...

In Germany, but in other countries as well, a trend towards a regionalisation in technol-ogy and innovation policy is clearly evident. This triggers the expectation towards universities to establish regional ties and networks and to exploit the advantages of spatial proximity to other research...
