This paper derives a three stage Cournot duopoly game for research collaboration, research expenditures and product market competition. The amount of knowledge firms can absorb is made dependent on their own research efforts, e.g. firms' absorptive capacity is treated as an endogenous variable....

Determining the research and development (R&D) boundaries of the firm as the choice between internal, collaborative and external technology acquisition has since long been a major challenge for firms to secure a continuous stream of innovative products or processes. While research on R&D...

Subsidized research joint ventures (RJVs) between public research institutions and industry have become increasingly popular in Europe and the US. We study the long-run effects of such a support scheme that has been maintained by the Danish government since 1995. To cope with identification...

We investigate the effect of mobility of highly skilled workers in Denmark on the total patenting activity of the firms involved for the population of R&D active Danish firms observed between 1999 and 2004. Our study documents how workers joining increase firms' patenting activity. The effect is...

In this paper it is tested which of the various alternative approaches for constructing knowledge spillover pools suggested in existing literature measures the extent to which a firm can costlessly receive external knowlegde best. Since knowledge spillovers are unmeasurable, a 'goodness of fit'...

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...

We review and condense the body of literature on the economic returns of public R&D on private R&D and find that: (i) private returns to R&D appear to be large and larger than the returns to alternative investments; (ii) private R&D and R&D subsidies are positively correlated and there is no...
