We reconsider the recent work by Okuguchi (J Econ 101:125–131, 2010) on (possibly asymmetric) Cournotian firms with two production factors, one being inferior for each firm. It is shown there that an increase in the price of the inferior factor does raise the equilibrium industry output. In addition of providing a simpler and more rigorous proof of that result, we generalize it to the case of technologies with $s\ge 2$ factors and also allow some firms not to use the inferior one. 相似文献

In this paper a firm’s R&D strategy is assumed to be endogenous and allowed to depend on both internal firm characteristics and external factors. Firms choose between two strategies, either they engage in R&D or abstain from own R&D and imitate the outcomes of innovators. This yields three types of equilibria, in which either all firms innovate, some firms innovate and others imitate, or no firm innovates. Firms’ equilibrium strategies crucially depend on external factors. We find that the efficiency of intellectual property rights protection positively affects firms’ incentives to engage in R&D, while excessive competitive pressure has a negative effect. In addition, smaller firms are found to be more likely to become imitators when the product is homogeneous and the level of spillovers is high. Regarding social welfare our results indicate that strengthening intellectual property protection can have an ambiguous effect. In markets characterized by a high rate of innovation a reduction of intellectual property rights protection can discourage innovative performance substantially. However, a reduction of patent protection can also increase social welfare because it may induce imitation. This indicates that policy issues such as the optimal length and breadth of patent protection cannot be resolved without taking into account specific market and firm characteristics. 相似文献

We analyze the effect of research joint ventures (RJVs) on consumer welfare in an international context when collusion can occur. Our results suggest that antitrust authorities should distinguish between domestic and international RJVs and be more benevolent with international RJVs. 相似文献

There is a contentious debate about the exclusionary effects of upfront payments to be made by manufacturers to place their products on retailers’ shelves. Analyzing a two-stage bargaining process with one downstream retailer and a pool of upstream manufacturers, we find that upfront payments lead to a smaller assortment if the retailer’s bargaining power is high enough and the suppliers’ products are close substitutes. 相似文献

This article seeks to establish a link between the field of business ethics and information ethics by exploring the connection between responsibility and the Internet from an economic perspective. This link finds its expression in the moral theory of Discourse Ethics as suggested by German philosophers such as Juergen Habermas and Karl‐Otto Apel. The term responsibility points in the direction of communication and therefore leads easily to discourse ethics. The economy in general and most economic practices also seem to be intimately linked to questions of responsibility. The growing spread and importance of the Internet poses new challenges and problems but also creates new possibilities for ethics as well as for the economy. Here several of these new developments are analysed and their impact on ethics as well as economy assessed. Consequences for the use and development of information technology are considered. 相似文献

This paper compares the second-best optimal tax on polluting consumption goods with the Pigovian tax, which would internalize marginal environmental damage at a second-best optimum. It is shown that the relationship between the optimal tax on polluting consumption and the Pigovian tax is determined by the substitutability between labour and polluting consumption or clean and polluting consumption, depending on whether a wage tax system or a commodity tax system is being considered. The key factor determining the relationship between the two taxes is gross substitutability between the two taxed goods. As long as there is gross substitutability, the optimal dirt tax exceeds the Pigovian tax. The opposite can occur if and only if the two goods are gross complements. 相似文献
