Cost-Reducing Alliances and Local Spillovers

Firms raise cost-reducing alliances before competing with each other, but cannot fully internalize the shared knowledge. When spillovers are local and transit through the network of alliances, stable architectures with a moderate level of asymmetry are identified.Oligopoly, Cost-Reducing alliances, Local spillovers, Network stability

Quality-improving alliances in differentiated oligopoly

We study rival firms' incentives in quality-improving Research and Development (R&D) networks. The analysis stresses the role of free riding associated to collaboration and three major consequences emerge: R&D efforts decrease with the number of partners, networks of alliances are over-connected as compared to the social optimum and the profitmaximizing number of alliances is possibly non monotonic (decreasing then increasing) with respect to inverse measure of product differentiation.Vertically and horizontally Differentiated Oligopoly, Product Innovation, R&D, Alliance

Standardization versus Preference for Variety in Linear Cournot Oligopoly

We consider a Cournot oligopoly setting in which consumers have an intrinsic preference for variety, while unit production costs of firms increase with the number of goods they produce. This environment exhibits a general under-provision of variety with respect to social welfare.Standardization; Preference for Variety; Oligopoly
