In this paper, we propose and analyze a two-stage oligopoly game in which firms first simultaneously choose production technologies and in the second stage simultaneously choose production quantities. After characterizing the Nash equilibrium of the game, we cast our static model in a dynamic setting exploring the stability properties of the market equilibrium in two different cases: (i) exogenously distributed technologies and Cournot adjustments and (ii) endogenously distributed technologies in an infinite population game with Cournot–Nash equilibrium outputs. The main aim of the paper is that of extending the results about Cournot oligopoly stability in an evolutionary setting of heterogeneous decreasing returns-to-scale technologies. We show how the interplay between production decisions and R&D decisions can generate endogenous market fluctuations leading to complex dynamic phenomena. 相似文献

The paper describes quality/price equilibrium and welfare effects of R&D spillovers when firms are located around the circumference of a Salop circle, and the extent of the spillovers may depend on the geographic proximity between firms. In particular, we show that an increase in competition may have a positive effect on the provision of quality and firms' profits. We also extend the model allowing a multinational enterprise to locate at the centre of the circle. In this scenario it is important to understand the interplay of local R&D spillovers with the spillovers that propagate from and to the centre. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献
