从总所有权成本看电子采购的价值

总所有权成本关注整个电子采购周期的总成本。通过对确定环境下和随机情况下的总所有权成本建模,可知电子采购在采购交易前、交易中和交易后整个过程中通过不同方面对采购产生价值。     

基于价值链和BCG方法的人力资源管理策略研究

随着信息技术的发展,企业价值的评估模型逐渐改变,并由传统强调实体资产转变为看不见的无形资产。文章旨在分析人力资源管理实务的价值链如何创造企业的竞争优势与价值,并以价值链模型为主,探讨企业人力资源管理实务的价值活动,同时分别从专业才能观点(Competency-Based Approach)与波士顿顾问群的BCG策略定位模型,建立企业策略与核心人力资源需求的关联模型,并进一步整合上述3种模型观点,提出人力资源管理决策模型的架构,建立人力资源管理策略评估模型,提供管理者对于人力资源管理决策的参考架构。

客户价值的评估方法

关系营销关注的是客户保留,企业要与顾客保持良好的客户关系。作为以赢利为目的的组织,企业很显然应把主要精力放在维护能给企业带来最大利益的客户关系上。本文介绍了几种评价客户关系价值的方法,并讨论了它们各自的缺陷,提出反映客户关系风险水平的经济价值评估法是对客户关系价值的更好的评价方法;同时指出,即使是经济价值评估法也有缺陷,客户关系的总价值应包括经济价值和很难用经济指标衡量的关系利益。最后提出了管理客户关系以最大化客户关系价值的几点建议。     

Nearly exact sample size calculation for powerful non‐randomized tests for differences between binomial proportions

In the case of two independent samples, it turns out that among the procedures taken in consideration, BOSCHLOO'S technique of raising the nominal level in the standard conditional test as far as admissible performs best in terms of power against almost all alternatives. The computational burden entailed in exact sample size calculation is comparatively modest for both the uniformly most powerful unbiased randomized and the conservative non‐randomized version of the exact Fisher‐type test. Computing these values yields a pair of bounds enclosing the exact sample size required for the Boschloo test, and it seems reasonable to replace the exact value with the middle of the corresponding interval. Comparisons between these mid‐N estimates and the fully exact sample sizes lead to the conclusion that the extra computational effort required for obtaining the latter is mostly dispensable. This holds also true in the case of paired binary data (McNemar setting). In the latter, the level‐corrected score test turns out to be almost as powerful as the randomized uniformly most powerful unbiased test and should be preferred to the McNemar–Boschloo test. The mid‐N rule provides a fairly tight upper bound to the exact sample size for the score test for paired proportions.     

On axiomatizations of the Shapley value for assignment games

We consider the problem of axiomatizing the Shapley value on the class of assignment games. It turns out that several axiomatizations of the Shapley value on the class of all TU-games do not characterize this solution on the class of assignment games. However, when considering an assignment game as a (communication) graph game where the game is simply the assignment game and the graph is a corresponding bipartite graph where buyers (sellers) are connected with sellers (buyers) only, we show that Myerson’s component efficiency and fairness axioms do characterize the Shapley value on the class of assignment games. Moreover, these two axioms have a natural interpretation for assignment games. Component efficiency yields submarket efficiency stating that the sum of the payoffs of all players in a submarket equals the worth of that submarket, where a submarket is a set of buyers and sellers such that all buyers in this set have zero valuation for the goods offered by the sellers outside the set, and all buyers outside the set have zero valuations for the goods offered by sellers inside the set. Fairness of the graph game solution boils down to valuation fairness stating that only changing the valuation of one particular buyer for the good offered by a particular seller changes the payoffs of this buyer and seller by the same amount.
