印度股票市场改革的经验与启示 总被引:1,自引:0,他引:1
印度股票市场改革对中国的启示主要在于,作为一个转型经济国家在发展金融市场尤其是股票市场的过程中出现某些消极问题在某种意义上是可以的,关键在于改革者要在既定的约束条件下完善相关的制度和规则,从而引导相关利益主体的行为以实现效率改进,同时在制度移植和模仿方面要注意有关的适用条件,在改革方式上宜快则快。 相似文献

This paper studies technology policy within a version of Jones's [1995. R&D-based models of economic growth. Journal of Political Economy 103, 759–784] non-scale R&D-based growth framework that incorporates imitation of foreign techniques. In the model, imitation is the most important source of productivity growth at the beginning of the convergence process, whereas innovation dominates later on. In addition, the transitional dynamics of the model can account for well-known empirical regularities regarding the relationship between the level of economic development and public support to technology innovation and imitation. The paper shows as well that, even though policy in Jones-type non-scale models has no long-run growth effects, level effects can be substantial. 相似文献

This paper provides a growth model in which innovation as well as imitation occurs. Economic growth is due to product innovations. Innovators driven by the possibility to appropriate monopoly profits do not remain in their monopolistic position forever. Latecoming imitators get into possession of the private knowledge of production through investments in R & D. Imitated products are marketed in oligopolistic markets. Imitation proves to be profitable despite a single factor market and positive imitation costs. A steady-state equilibrium with positive imitation and innovation rates as well as different market structures can be derived. Finally, the effects of industrial policy measures are discussed. 相似文献

模仿行为经济学分析——对经济波动的一种新解释 总被引:9,自引:0,他引:9
当前 ,世界经济面临衰退的威胁 ,科学解释经济波动具有重大的理论意义和现实意义。RBC理论或方法是当代西方经济学界解释经济波动最具前沿的一种理论或方法 ,也是宏观经济分析的方向。但存在明显缺陷。本文在修正RBC模型的基础上 ,首次建立模仿行为理论模型重新解释经济波动 ,并就中国政府在防止和治理经济波动的作用进行了独特的解释 ,认为政府所起的作用是示范人作用。 相似文献

处于不同生命周期的企业面临的策略选择是不同的,通过博弈模型的假设,分析了企业合作与竞争的影响因素,结合企业不同发展阶段的影响因素的特点,提出了不同阶段的策略模式选择。从企业的不同生命周期的模型假设看出,竞争与合作策略选择是随着企业不同的发展阶段,各自的成本,收益以及在市场上是否处于有利地位的不同而不同的。对于企业而言,处于不同的生命周期,其面对的内外部环境是不同的,因此选择不同的战略模式,即选择不同降段的创新模式来实现各自更好更快的发展。 相似文献

We examine human capital's contribution to economy-wide technological progress through two channels – imitation and innovation – innovation being more skill-intensive than imitation. We develop a growth model based on the endogenous ability-driven skill acquisition decision of an individual. It is shown that skilled human capital is growth enhancing in the “imitation-innovation” regime and in the “innovation-only” regime whereas unskilled human capital is growth enhancing in the “imitation-only” regime. Steady state exists and, in the long run, the economy converges to the world technology frontier. In the diversified regime, technological progress raises the return to ability and generates an increase in wage inequality between and within groups – consistent with the pattern observed across countries. 相似文献

文章通过将中间产品生产厂商的技术投资选择引入罗默三部门内生增长模型中,构建了一个基于水平创新的技术进步模型。运用该模型对技术追随国技术赶超中厂商的技术投资选择与模仿向自主创新转型的问题进行研究。通过研究发现,技术赶超过程中经济运行的路径要经历模仿、创新两个均衡点。厂商利润为正时会进行技术投资,而厂商的技术投资选择模仿或者是创新会影响经济能否顺利跨越模仿陷阱而跃迁到创新均衡点。经济中能影响厂商技术投资选择的内部和外部因素都会对跨越模仿陷阱产生相应的作用;技术赶超国应该积极地提高企业的价值,提高技术知识储备和高人力资本的储备,同时还要大力建设国家的创新能力为企业创新营造一个好的创新环境。 相似文献

Naive learning and cooperation in network experiments 总被引:1,自引:0,他引:1
In this paper we study learning and cooperation in repeated prisoners' dilemmas experiments. We compare interaction neighbourhoods of different size and structure, we observe choices under different information conditions, and we estimate parameters of a learning model.We find that naive imitation, although a driving force in many models of spatial evolution, may be negligible in the experiment. Naive imitation predicts more cooperation in spatial structures than in spaceless ones—regardless whether interaction neighbourhoods have the same or different sizes in both structures. We find that with some interaction neighbourhoods even the opposite may hold. 相似文献

This paper aims to study those firms which have similar characteristics at the beginning of time. The objective is to observe the relation that exists between technological evolution, firms' performances and economic instability. This is done using an adaptation of the Nelson and Winter model, in order to show the possibility of various growth trajectories, and also to underline the heterogeneity of the firms. This heterogeneity corresponds to a period of economic instability, and itself only exists as a result of the specific nature of the technological trend. The theoretical interest lies in using the structures/performances relation, by according a central place to innovation. 相似文献
