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 study firms' adoption of flexible versus dedicated technologies in the context of a mixed versus a private duopoly with product differentiation. The flexible technology allows a firm to become multiproduct or multimarket without bearing additional costs. We find that a configuration where...

We analyze a simple oligopoly model where firms can engage in cost-reducing Ramp;D. We compare two Ramp;D regimes: Ramp;D competition and Ramp;D cooperation where firms can enter in a Research Joint Venture (RJV). We introduce coordination costs for the RJV and examine how these affect the...

We examine the relationship between competition and innovation in an industry where production is polluting and R&D aims to reduce emissions ("green" innovation). We present an n-firm oligopoly where firms compete in quantities and decide their investment in "green" R&D.When environmental...

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...

We study the decision of two rms 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...

We present a theoretical framework in which an elitist and a non-elitist university in a developed country compete by choosing their admission standards and deciding whether or not to open a branch campus in a developing country. Students from a developing country attend university if either a...

We investigate the use of subsidies to R&D, both in a mixed and a private duopoly market. We show that the socially optimal R&D subsidy is positive and increasing in the degree of spillovers both in the private and the mixed duopoly, although it is lower for the former than for the latter. We...
