This Element offers a review and synthesis of the theoretical analysis of mixed oligopoly, that is a hybrid market structure in which public (state-owned) and private firms interact, using a variety of strategic variables. A distinguishing feature of a mixed oligopoly is that firms have...

We consider a simple oligopoly model where firms engage in cost-reducing R&D and compare two R&D regimes: R&D competition and R&D cooperation in the form of a research joint venture (RJV). We introduce coordination costs for the RJV and examine how these affect the equilibrium outcomes.

We present a model of spatial price discrimination where R&D spillovers are endogenous as they depend on firms' location. We establish that both the distance between locations and R&D efforts are an increasing function of the transportation cost coefficient and show that there is a continuum of...

We address the following question: how does a higher education funding system influence the trade-off that universities make between research and teaching? We do so by constructing a model that allows universities to choose actively the quality of their teaching and research when faced with...

This paper considers a model of horizontal and vertical product differentiation. Firms spending on R&D may improve the quality of their product. K&D cooperation in the fort11 of a RJV among a subset of innovating firms introduces the possibility of a much better product being produced relative...
