论卓炯经济理论的生命力

本文认为，卓炯虽然离开我们十多年，但是，卓炯经济思想仍然具有强大的生命力。卓炯在马克思主义经济理论研究上取得的成就，仍然处于理论前沿。卓炯的分工理论，不但是古今经济学家着迷的课题，还是20世纪80年代兴起的新兴古典经济学的理论基础。卓炯关于市场机制配置资源优化的市场经济理论，不但是古典、新古典经济学的理论核心，还是经济学永远绕不开的中心论题。卓炯提出的市场经济模式经受了改革开放实践的考验，继续放出夺目的理论光彩。继承和发展卓炯经济理论是广东经济学家的光荣和骄傲．是义不容辞的理论任务。     

MANAGING VENDOR INVENTORY IN A DUAL LEVEL DISTRIBUTION SYSTEM

Collaborative arrangements among members of the supply chain have received a great deal of interest in recent years as a means of reducing costs. One such arrangement is vendor managed inventory (VMI). VMI allows the vendor to make decisions concerning the quantity and timing of deliveries to the retailer. Such an arrangement offers the potential of a more efficient supply chain by removing the negative effects of retail ordering policies. A thorough review of the literature was conducted to identify factors likely to impact the performance of a VMI partnership. Computer simulation was used to study the effects of these factors from both the vendor's and retailer's perspectives. The results lend insight into the performance of VMI and guidance for managers as to the environments in which VMI is most effective.

对高等院校知识管理的几点思考

知识管理越来越受企业重视,在高校教育中实施知识管理虽有很多困难,但已成为必然趋势。只有做好充足的先前准备,掌握实施知识管理的重点步骤和方法,高等院校知识管理才能迈向一个新台阶。     

论人为添附中新物的所有权归属

添附是引起物权取得、丧失的原因之一。在各国民法中,无论是出于自然原因还是人为原因,往往规定附合、混合中主物或价值明显较高的物主取得新物的所有权,经加工后价值明显高于原物的加工人取得所有权,且均不问所有人或第三人主观是否出于善意。此问题在学界依然存在争议。本着符合法律公正精神,探讨当添附系于人为时,就其添附所有权具体分配,提出了具体归属意见。

20世纪前期买办职业收入分析

20世纪前期,买办的职业报酬制度达到成熟和完善。买办的职业收入主要由薪金和佣金构成,还有一部分被外商默许的暗中收入。佣金是多数买办的主要收入,是买办经纪人身份的体现;薪金是买办与外商雇佣关系的一种象征。买办收入的复杂挂还在于不同行业的买办收入来源不一,且差距较大。     

Asymptotic subadditivity/superadditivity of Value-at-Risk under tail dependence

This paper presents a new method for discussing the asymptotic subadditivity/superadditivity of Value-at-Risk (VaR) for multiple risks. We consider the asymptotic subadditivity and superadditivity properties of VaR for multiple risks whose copula admits a stable tail dependence function (STDF). For the purpose, a marginal region is defined by the marginal distributions of the multiple risks, and a stochastic order named tail concave order is presented for comparing individual tail risks. We prove that asymptotic subadditivity of VaR holds when individual risks are smaller than regularly varying (RV) random variables with index −1 under the tail concave order. We also provide sufficient conditions for VaR being asymptotically superadditive. For two multiple risks sharing the same copula function and satisfying the tail concave order, a comparison result on the asymptotic subadditivity/superadditivity of VaR is given. Asymptotic diversification ratios for RV and log regularly varying (LRV) margins with specific copula structures are obtained. Empirical analysis on financial data is provided for highlighting our results.
