The present paper uses a setting where firms commit to environmental R&D expenditure that reduces their emission levels before the regulator sets the emission tax. It examines two scenarios with respect to the organisation of environmental R&D: (i) independent R&D and (ii) an industry-wide...

We analyse how spatial disparities in innovation activities, coupled with migration costs, affect economic geography, growth and regional inequality. We provide conditions for existence and uniqueness of a spatial equilibrium, and for the endogenous emergence of industry clusters. Spatial...

We develop a model of a mixed oligopoly to examine the role of R&D subsidies and evaluate the welfare effects of privatization. In solving the (n 1)-firms oligopoly model we make use of aggregative games techniques. Our analysis reveals that privatization reduces the optimal R&D subsidy, but...

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 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....

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...
