Designing Agent-Based Electronic Employment Markets

Two modes of matching people with jobs prevail at present: 1) hierarchical planning and 2) distributed markets. Each has strengths and limitations, but few systems have been designed to take advantage of strengths corresponding to both. With evolving information technology, however, the job-matching process could be accomplished far more equitably and efficiently using web-based markets within the firm, and intelligent agents offer excellent potential to help both potential employees and employers find one another in a distributed, electronic marketplace. But realizing this potential goes well beyond simply changing the rules of internal job matching or making agent technology available to job searchers. Rather, the corresponding markets and technologies must be designed, together, to mutually accomplish the desired results (e.g., efficient and effective matching) and conform to necessary properties (e.g., market clearing). Through the research described in this paper, we draw from Game Theory results to assess the feasibility of using two-sided matching algorithms to address this market-design problem. We also draw from current agent research to address the information technology dimension of the problem by implementing a proof-of-concept multi-agent system to enact, automate and support the corresponding market solution. This paper integrates the key economic and technological elements required to design robust electronic employment markets. And the corresponding research provides new knowledge and insight into co-development of the requisite economic markets and agent technologies.

Modeling Instrumental Rationality, Land Tenure and Conflict Resolution

Full instrumental rationality and perfect institutions are two cornerstoneassumptions underlying neoclassical models. However, in the real world, thesetwo assumptions never hold, especially not in developing countries. In thispaper, we develop a game theoretical model to investigate if relaxations inthe full instrumental rationality and perfect institutions premise can explainthe conflicts that have been occurring between the various principals in theNarok district in Kenya with regard to land tenure and use.     

银行分销渠道整合的位置-产量模型研究

在新金融条件下,如何有效整合银行传统的分销渠道而使其在新的挑战面前不失昔日风采,这是金融理论界和实践界近年来一直在探讨的问题。本文从博弈论的角度,建立一个位置-产量博弈模型来探讨此问题,通过求解博弈模型的均衡解,得出的结论是,当银行产品替代性较大时,银行的分销渠道应尽量分散化;当银行产品具有互补性时。银行的分销渠道应尽量集中化;当银行产品没有替代性或互补性时,银行的分销渠道选择具有较大任意性。据此,分析了我国银行网点设置不合理的原因及提出了有效整合我国银行业分销渠道的两点建议。     

悖论对策中的计算机仿真研究

社会悖论是在社会生活中大量存在的多人非合作博弈问题，但用经典对策论难以得到有意义的结果。该文应用计算机试验的方法，对一类多人重复悖论对策过程进行仿真研究，以进化对策的观点，研究在不同环境下不同模型的各种策略法则的性能，以及对策的优化解。这个结果为社会悖论的进化对策研究及其在社会经济方面的应用提供一种有效的研究手段。

道德接受是发生在道德领域中的特殊的接受活动.道德接受活动是一个复杂的过程,其中,道德需要是道德接受的动力,道德选择是道德接受的前提,道德内化是道德接受的关键,道德环境是道德接受的外部条件.     

定义在非闭集上的二人零和连续凸对策

在二人零和对策中,为了确保对策的值及最优策略的存在性,局中人纯策略集为闭集是一个至关重要的条件。本文讨论了一类定义在非闭集[a,b]×[c,d)或[a,b)×[c,d]上的二人零和连续对策,其最优策略的存在性问题。着重研究其赢得函数为凸(或凹)函数时,最优纯策略的存在性。

无可信中心的门限身份认证方案及其博弈分析

提出了一种在无可信中心的情况下由组中成员共同颁发证书的安全门限身份认证方案.该方案利用门限的思想,从n个认证参与者中选取七个参与者依次对待验证者颁发子证书,当待验证者接到七个子证书时可以合成最终的证书.该方案还提出了惩罚机制,并将该机制运用到协议中.该方案将认证过程分为初始化阶段、密钥生成阶段、子证书生成阶段、证书合成阶段和证书验证阶段,并在标准模型下对各个阶段进行了安全性的博弈分析,表明该方案是健壮、安全的.
