    Abstract: We study a model where innovation comes in two varieties: improvements on existing products, and new products that expand the scope of a technology. We make this distinction in order to highlight how market structure can determine not only the quantity of innovation but also its direction. We study two market structures. The first is the canonical one from the endogenous growth literature, where innovations can be developed by anyone, and developers market their own innovations. We then consider a more concentrated industry, where all innovation and pricing for a given technology is monopolized. We study the implications of the different market structures for both types of innovation, focusing on differences they induce in the direction of technological change. We apply our model model to the case of a hardware/software technology and analyze which market structure offers greater profits to a monopolist who can monopolize either hardware or software. We compare social welfare across the market structures, and discuss whether one type of innovation should be subsidized over another

    Abstract: In the framework of analyses on the relationship between geography and technological innovation, the role of universities has received considerable attention. Both theoretical and empirical literature has shown that university research positively influences the capacity for innovation of the surrounding firms (Jaffe, 1989; Feldman, 1994; Acs et al, 2002). Universities play a central role in innovation processes both as the main responsible for basic research and also as forgers of human capital’s skills. Empirical work has highlighted that such effects radiate from major university centres crossing borders and administrative boundaries (Anselin et al., 1997). This paper focuses on the relationship between universities and the innovative capacity at the territorial level. Specifically, our empirical analysis investigates whether university research spillovers are highly localised or they rather flow across borders. Empirical literature has widely investigated intensity and directions of such spillovers, mainly within the theoretical framework of Griliches-Jaffe. However, we extend the empirical evidence exploring whether intensity and directions of spillovers depend on universities’ specificities (e.g. size, fields of specialization, fund rising capacity) and on the local absorptive capacity. The analysis is developed at the Italian NUTS3 level, using an explicit spatial econometric approach applied to a knowledge production function. References Acs, Z., Anselin, L., and Varga, A.
