This paper builds a theoretical foundation for the dynamics of knowledge sharing in private industry. In practice, research and development projects can take years or even decades to complete. We model an uncertain research process, where research projects consist of multiple sequential steps....

This paper analyzes the effects of cooperative R&D arrangements in a model with stochastic R&D and output spillovers. Our main innovation is to allow for free entry in both the R&D race and product market. Moreover, in contrast with the literature, we assume that cooperative R&D arrangements do...

We investigate optimal rewards in an R&D model where substitute ideas for innovation arrive to random recipients at random times. By foregoing investment in a current idea, society as a whole preserves an option to invest in a better idea for the same market niche, but with delay. Because...

We investigate rewards to R&D in a model where substitute ideas for innovation arrive to random recipients at random times. By foregoing investment in a current idea, society as a whole preserves an option to invest in a better idea for the same market niche, but with delay. Because successive...

We consider a model of the innovative environment where there is a distinction between ideas for R\&D investments and the investments themselves. We investigate the optimal reward policy and how it depends on whether ideas are scarce or obvious. By foregoing investment in a current idea, society...

This paper investigates the relationship between firm longevity and rat races in an environment where long-lived firms are operated by overlapping generations of short-lived players. We first present a complete information model in which workers in the young generation are offered employment...

Antitrust authorities regard the possibility of post-merger entry and merger-generated efficiencies as two factors that may counteract the negative effects of horizontal mergers. This article shows that in differentiated oligopolies with linear demand, all entry-inducing mergers harm consumer...
