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 investigate the imposition of a horizontal technical barrier to trade (HTBT) in a symmetric, cross-hauling duopoly. Tariffs and subsidies are ruled out, but, in the absence of a mutual recognition agreement, it is possible for governments to impose HTBTs, so long as firms apply different...

We examine the impact of an optimal emissions tax on research and development of emission reducing green technology (E-R&D) in the presence of R&D spillovers. We show that the size and effectiveness of the optimal emissions tax depends on the type of the R&D spillover: input or output spillover....
