Innovation, Imitation and Intellectual Property Rights: A Note on Helpman's Model

This note analyses the effect of the policy of tightening Intellectual Property Rights (IPR) on the rate of innovation in the North and on the welfare in both North and South in a model which is otherwise identical to Helpman (1993) except in the concept of knowledge capital. We assume that the South based imitated products do not contribute to the knowledge capital in the North. It is shown that the tightening of IPR raises the rate of innovation in the North and may improve the welfare of both North and South. These results are significantly different from those in Helpman (1993).

论节约型社会的营销创新探析

营销活动对环境的变化是非常敏感的。在变化的环境下，营销活动必须有所创新，才能在市场中立于不败之地。我国政府将“建设资源节约型、环境友好型社会”作为基本国幕，标志着我国进入建设节约型社会时期。节约型社会建设中营销环境的变化，对企业营销活动提出了新的要求，企业营销应从观念、产品、渠道等方面进行创新以适应新的环境，形成企业新的竞争力。     

Diffusion and Innovation of New Technologies under Skill Heterogeneity

This article presents a model of innovation and diffusion of machines which embody a new technology. Users of the machines are heterogenous in their skill level. Skilled machine-users adopt new machines first, while unskilled users wait until machines become more user-friendly and reliable. The improvement of machines is the engine of diffusion, and it is carried out by the monopolist machine producer. The speed of diffusion is affected by the skill distribution in the economy. At any point in time, the machine producer can innovate a new generation of machines. The timing of innovation is also influenced by the skill distribution.     

农地利用技术创新的类型与模式研究

农地利用技术是一个多层次的体系，它能在扩大耕地面积、提高土地利用率和耕地质量等多方面发挥重要作用。通过对“市场机制自发作用下的技术选择”和“政府引导下的技术选择”两种现实模式的探讨，认为技术创新具有外部性，土地利用更是具有明显的“外溢效应”，加上我国农业比较利益偏低和农地使用权流转市场发育不全带来的农地价格扭曲，常造成市场机制下技术创新的方向与资源稀缺状况不相符合的现象，从而带来资源配置的低效率。因此，适当的政府引导是必要的，也是有效的。     

Entrepreneurship,Austrian Economics,and the Quarrel Between Philosophy and Poetry

I consider whether entrepreneurship is a distinct category within economic theory. More generally, I consider the links between discussions of entrepreneurship and philosophic debates over the nature of the aesthetic. For instance, Kant's attempt to elevate the category of the aesthetic has much in common with Kirzner's attempt to elevate the concept of the entrepreneur. Shackle's theory of choice refers very directly to the notion of the aesthetic. Theories of the aesthetic and theories of the entrepreneur have common strengths and weaknesses.     

Racing in two dimensions

In this paper we study an industry in which there is an ongoing sequence of R&D races between two firms. Firms are engaged in product innovation. Products are horizontally and vertically differentiated. There are two key characteristics/dimensions to products, and the level at which these are embodied in products can be increased by R&D. At each time firms can spend R&D on improving their product in one or both dimensions. We allow the possibility of economies scope — so R&D undertaken in one dimension can spillover to the other. The question we are interested in is whether a firm that is ahead in a single dimension but behind in another will focus all its R&D effort in the area in which it is ahead (product specialisation), or whether it will try to do R&D in both dimensions in the hope that it might get ahead in both and end up with a superproduct that dominates in both characteristics. The outcome of this R&D competition determines a Markov transition probability matrix determining the evolution of the industry. We show that when the R&D technology is characterized by constant returns then the only steady-state outcome is one in which the economy stays forever in a position in which one firm produces a super-product and the other gives up doing R&D altogether. This outcome is unaffected by the degree of economies of scope. When the R&D technology is characterised by decreasing returns, then the industry will visit all states and so will exhibit both product specialisation and superproduct dominance at various times. Now the extent of economies of scope matters and we show that the greater the extent of economies of scope, the less likely is the industry to exhibit product dominance, and the more likely it is to exhibit product specialisation.
