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.     

我国绿色食品出口贸易中存在的问题及对策探析

20世纪90年代以来,绿色食品贸易在全球兴起并已成为人类社会可持续发展的必然选择。然而,尽管在国内绿色食品生产日益社会化、市场化、国际化的背景下,我国绿色食品已经呈现出蓬勃发展的良好态势,但出口数量和出口规模还是偏低。本文在分析我国绿色食品出口中存在的问题及原因的基础上,探索相应的对策,以期为我国绿色食品竞争优势的提升提供有益的思路。

本文应用动态规划的原理,讨论了多期投资决策中基于总收益率最大的交易策略的设计和实现问题。通过比较随机交易方法、局部最优方法和全局最优方法下的投资表现,在交易费用存在的情况下,基于动态规划的算法给出问题的全局最优解,该方法的优越性随着交易费用的增长而加强。     

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。     

会计职务犯罪的心理学分析

近年来有的财会人员经不住种种诱惑,采取非法手段,侵害国家、集体和人民的利益,其突出表现为做假帐。本文从心理学的角度分析了会计职务犯罪产生的因素,会计职务犯罪对社会的危害。最后,对如何预防会计职务犯罪,运用制度经济学原理从宏观和微观两方面提出了建议。     

企业创新体系研究

企业在市场中的竞争表面上是产品的竞争、技术的竞争,实质上却是隐含于产品、技术背后的企业之间创新能力、创新意识的竞争。“在创新中求发展”已成为企业界的共识。但企业究竟该如何创新,从哪些方面进行创新,成了企业经营中较为困惑的问题。本文在分析创新概念的基础上,提出了企业创新体系的目标及总体构建,并对创新体系的主要内容进行了具体研究,为企业创新实践提供参考。     

会计管制与公司治理

本文从企业契约理论出发,在回顾会计管制国际经验的基础上,将会计管制引入对公司治理问题的思考,指出了会计管制目标的实现对解决公司治理问题的重要性。其不仅要求反思会计管制理论与实践,同时要求在具体分析公司治理模式的基础上,重新思考会计管制的目标及其实现问题。提出应从现行公司治理框架下改进会计管制措施,从而实现会计管制与公司治理的良性互动。
