We examine the use of subsidies to R&D in a mixed and a private duopoly market. We show that the socially optimal R&D subsidy is increasing in the degree of spillovers but it is lower in the private duopoly. The optimal R&D subsidy leads to an increase in total R&D and production, however, it...

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 increasing functions of the transportation cost coefficient and show that there is a continuum of...

We present a three-stage game where two firms choose location, R&D and price, under the assumption that R&D spillovers depend on firms' location. That is, the closer firms are to each other, the greater the benefit they receive from their rivals' efforts in quality-enhancing R&D. We show that...

We study the decision of two firms within an oligopoly concerning whether to enter into a horizontal agreement to exploit complementarities between their R&D activities and, if so, whether to merge or form a research joint venture (RJV). In contrast to horizontal merger, there is a probability...
