Endogenous human capital accumulation, comparative advantage and direct vs. indirect redistribution

Recently, several papers have reexamined the so-called production efficiency theorem and the Atkinson and Stiglitz theorem on commodity taxes in the optimal taxation literature. Naito [J. Public Econ. 71 (1999) 65] showed that indirect redistribution through production distortion or consumption distortion can Pareto-improve welfare and that the two theorems do not necessarily hold when different factors are imperfect substitutes and factor prices are endogenous. On the other hand, Saez J. Public Econ. (2002) forthcoming argued that in the long run, where human capital accumulation is endogenous, the two theorems are still valid. This paper develops reasonable alternative models where individuals accumulate human capital based on their comparative advantage. The present paper shows that the production efficiency theorem is not necessarily valid and that indirect redistribution from the able to the less able such as tariffs and production subsidies can increase efficiency even when skill accumulation is endogenous.     

Catching up and falling behind,a vintage model approach

The literature on catching up suggests that due to diffusion and imitation, relatively backward countries should grow at a faster rate. A model along lines suggested by Abramovitz is constructed to examine this. A country's change in productivity (technological gap) is supposed to depend on the productivity gap itself (relatively backwardness), social capability of adopting new technology, and R&D-activity. Together with a vintage growth model, this set-up gives a lot of different possible explanations of why growth rates differ among nations. The possibilities of both catching up and falling behind are considered.     

Core structure and comparative statics in a hybrid matching market

Flexible firms compete by means of wages in the Assignment market while rigid firms have no flexibility over terms of appointment in the Marriage market. Workers trade with both kinds of firms in the hybrid market.Examples show that standard results that characterize the core of the Marriage market (respectively, Assignment market) are not robust to the entrance of flexible (respectively, rigid) firms to this market. A new algebraic structure provides a different characterization for the core of the hybrid model and reflects a sort of robustness to the exit of rigid (respectively, flexible) firms from this market. Meaningful comparative static results are derived.     

西部大开发战略与武汉城市功能的发挥

西部大开发战略的实施 ,为武汉这个中部特大中心城市的发展提供了机遇 ,如何顺势起飞 ,关键在于武汉中心城市功能的发挥。处于中部承东启西 ,九省通衢 ,基础强劲的武汉特大中心城市功能的发挥 ,也会有力地促进西部大开发战略的落实。武汉立足于其区位综合优势 ,从集散功能、生产功能、管理功能、服务功能、创新功能发展出发 ,借西部大开发之势重构和强化其金融商贸中心功能、交通枢纽功能、通讯信息中心功能、科技教育文化中心功能、生产和服务中心功能 ,是武汉发展和西部大开发的双赢策略。     

企业网络组织协同竞争的理论与效应解析

竞争与合作相统一的协同竞争已成为企业网络竞争战略发展的必然趋势。通过对企业网络组织协同竞争研究脉络的梳理，可构建协同竞争研究的评析架构。其理论演进是：以系统思维作为理论逻辑的基点，以合作竞争为行动策略，以价值创造作为网络协同竞争的本质属性；在实践效应上，协同竞争具有提升竞争优势的特征，而博弈模型对协同效应发挥着解析工具的作用。     

会计价值机制论

本文认为,市场和企业是组织经济活动的形式,也是组织价值信息传递和价值激励的系统。市场价格机制是在长期市场供求关系作用下而形成的,而会计价值机制是随着企业的发展不断演化,在企业目标引导下组织价值信息传递和价值信息激励,以促成企业目标实现。企业替代市场或取得竞争优势,都是基于相同的原因和两种机制作用的结果,即是通过企业提供的产品或服务的成本低于市场价格而实现的。     

A substitution orbit model of competitive innovations

Successful innovation and diffusion of technology can be attributed to the identification of the orbit of emerging new technologies that complement or substitute for existing technologies. This dynamism resembles the co-evolution process in an ecosystem. In an ecosystem, in order to maintain sustainable development, the complex interplay between competition and cooperation, typically observed in predator-prey systems, create a sophisticated balance. Given that an ecosystem can be used as a masterpiece system, this sophisticated balance can provide suggestive ideas for identifying an optimal orbit of competitive innovations with complement or substitution dynamism.Prompted by such a sophisticated balance in an ecosystem, this paper analyzes the optimal orbit of competitive innovations and, on the basis of an application of Lotka-Volterra equations, it reviews substitution orbits of Japan's monochrome to color TV system, fixed telephones to cellular telephones, cellular telephones to mobile Internet access service, and analog to digital TV broadcasting. On the basis of substitution orbits analyses, it attempts to extract suggestions supportive to identifying an optimal policy option in a complex orbit leading to expected orbit.Key findings include policy options that are effective in controlling parameters for Lotka-Volterra equations leading to expected orbit.     

全面风险管理框架与内部控制整体框架的比较分析

2004年美国COSO委员会在其1992年发布的《内部控制整体框架》基础上,吸收各方面风险管理研究成果,颁布了《全面风险管理框架》(Enterpris Reisk Management Framework),旨在为各国的企业风险管理提供一个统一术语与概念体系的全面的应用指南。本文首先回顾了《内部控制整体框架》的产生及其贡献与不足,其次阐述了风险管理与内部控制的关系,最后比较分析了《全面风险管理框架》与《全面风险管理框架》的联系与区别,以期对理解、掌握和执行《全面风险管理框架》有所裨益。     

Competitive equilibrium when preferences change over time

Summary. We show the existence of a competitive equilibrium in an economy with many consumers whose preferences may change over time. The demand correspondence of an individual consumer is determined by the set of subgame-perfect equilibrium outcomes in his intrapersonal game. For additively separable preferences with concave period utility functions that are unbounded above, this demand correspondence will satisfy the usual boundary conditions. Whenever consumers can recall their own mixed actions, this correspondence is convex-valued. This ensures the existence of a symmetric competitive equilibrium.Received: 29 July 2004, Revised: 17 November 2004, JEL Classification Numbers: D51, D91, C73.
