We estimate the relative contribution of mobile scientists who leave academia for the private sector on the subsequent innovative performance of the firms they join. We use data on the population of Danish firms and their R&D workers for the period 1999-2004 and measure innovation performance by...

The transfer of knowledge and technology from academia to industry is usually understood as a process. While previous research focuses on phenomena along the process and its outcomes, the starting point of the process - the initiation of a transfer activity - remains unstudied. We provide first...

Why do some innovators freely reveal their intellectual property? This empirical puzzle has been a focal point of debate in the R&D literature.

I study the incentives of Cournot duopolists to share their technologies with their competitor in markets where intellectual property rights are absent and imitation is costless. The trade-off between a signaling effect and an expropriation effect determines the technology-sharing incentives. In...

This study shows for a large sample of R&D-active manufacturing firms that collaborative R&D has a positive effect on firms' patenting in terms of both quantity and quality. When distinguishing between alliances that aim at joint creation of new knowledge and alliances that aim at exchange of...
