超越契约理论--演化论视角的企业理论研究

企业的契约理论围绕交易成本概念解释了企业的存在、边界和内部组织,但严重忽视了企业的技术和生产功能,演化经济学的企业理论通过研究企业内知识的产生、传播和利用过程,以及组织与个人的交互学习,不仅重新解释了企业的存在、边界和内部组织问题,还研究了契约理论未触及的企业异质性、竞争优势和企业家等问题.     

我国体验式旅游开发初探

文章从体验式旅游内涵出发,研究分析了我国体验式旅游开发的现状及环境。指出现阶段我国体验式旅游开发仍处于增加体验环节和体验要素的初级阶段。其开发应分两步走:首先从提供旅游(服务)产品转向提供体验型旅游产品(体验旅游开发的初级阶段);再则从提供体验型旅游产品到提供旅游体验(体验旅游开发的成熟阶段)。目前,国内应重点开发体验型旅游产品。     

技术学习——企业技术能力演进的分析框架

企业技术能力的演进是一个技术学习过程,本文对技术能力和技术学习的基本内涵进行了分析和探讨,并提出了一个企业技术能力发展决定因素和机制的分析框架。我们认为,为获取技术能力发展所需要的知识和技能,技术学习需要整合三个维度的知识学习:个人学习与组织学习,内部知识学习与外部知识学习,以及显性知识与隐性知识的学习。因此,企业技术学习应该包含以下四个子过程:外部知识获取、内部知识获取、知识编码化以及知识社会化。由于这四个过程所获取的知识来源,性质不同,为完成这些子过程所需要的资源和机制也各不相同。通过对各个子学习过程决定因素和机制的分析识别,综合起来,我们为分析企业技术能力获取的决定因素和内部机制提供了一个基本理论框架。     

The convergence of least squares learning in stochastic temporary equilibrium models

Summary. This paper provides conditions for the almost sure convergence of the least squares learning rule in a stochastic temporary equilibrium model, where regressions are performed on the past values of the endogenous state variable. In contrast to earlier studies, (Evans and Honkapohja, 1998; Marcent and Sargent, 1989), which were local analyses, the dynamics are studied from a global viewpoint, which allows one to obtain an almost sure convergence result without employing projection facilities.

Cost Uncertainty and Unilateral Abatement

Unilateral abatement is sometimes advocated in order to set a good example that will make other countries follow. The aim of this paper is to investigate whether existence of correlated cost uncertainty provides an incentive for a country to undertake unilateral abatement. The theoretical model is driven by two main mechanisms; first, a learning effect, as the follower country might reduce its risk premium as it can observe the cost level in the leader country. Second, there is the public good effect, i.e., the marginal benefit of abatement declines when abatement is a public good and other countries contribute to pollution reductions. Results shows that unilateral abatement would be efficient in reducing uncertainty about the unit costs of abatement if a country with low cost uncertainty would undertake abatement first, while a country with initially high cost uncertainty would follow. However, countries may prefer to act simultaneously because of the larger uncertainties that are inherent in a sequential game.      

关于非英语专业高职学生学习自主性问题的探讨

本文通过对某高职院校非英语专业学生英语学习的自主性、元认知、兴趣、动机、自信度、焦虑度测试的分析研究表明:英语学习的自主性和性别及英语的学习成绩、兴趣、动机、自信度有非常显著的正相关性,而和英语学习元认知没有相关性,同时和英语学习焦虑度有非常显著的负相关性,从而为构建有效的培养英语学习自主性的教学模式提供依据,并就此提出若干提高学生英语学习自主性的建议。     

供应链分销系统奖金优化与仿真分析

研究由多个制造商与一个零售商组成的分销系统，他们以各自的利润最大化为目标，制造商给零售商提供奖金激励，零售商提供对应于奖金激励的服务水平，制造商需要进行为零售商提供多大奖金激励的决策。利用强化学习的启发式学习算法来优化制造商应提供的最优奖金激励。

Social learning with private and common values

Summary. We consider an environment where individuals sequentially choose among several actions. The payoff to an individual depends on her action choice, the state of the world, and an idiosyncratic, privately observed preference shock. Under weak conditions, as the number of individuals increases, the sequence of choices always reveals the state of the world. This contrasts with the familiar result for pure common-value environments where the state is never learned, resulting in herds or informational cascades. The medium run dynamics to convergence can be very complex and non-monotone: posterior beliefs may be concentrated on a wrong state for a long time, shifting suddenly to the correct state.Received: 6 January 2005, Revised: 5 May 2005, JEL Classification Numbers: C72, D82.Jacob K.

基于互惠合作的供应链合作关系稳定机制研究

首先应用强化学习算法对供应链合作关系的稳定机制进行研究;其次从生物学的角度研究了供应链合作关系中的互惠利他合作行为;最后利用计算机进行了系统仿真.研究得出：只要供应链合作关系中存在互惠利他型的企业,不管其所占的比重有多大,该企业都会通过强化学习使得互惠利他行为在供应链中扩散开来,最终达到企业间合作的一种稳定状态.
