Industrial life cycles and learning curves: Interaction of marketing and production

The price-oriented experience curve has been widely utilized as a model to design marketing strategies. Yet, it is cost over which many firms exercise the most control. This article explores the cost-oriented learning curve in conjunction with the product life cycle model as joint strategy constructs. Implications of variations in the learning curve parameters are examined.     

Marketing versus public relations in selling nuclear power

All too often, the terminology and practices of public relations are used when marketing is what is really needed. This misapplication appears most often when a concept, an idea, or an intangible product is involved. Webster defines public relations as: relations with the general public through publicity; those functions of a corporation, organization, branch of military service, etc., concerned with informing the public of its activities, policies, etc., and attempting to create favorable public opinion.This definition implies a general, ongoing effort to supply information supporting the image of an organization. There is, however, a considerable difference between this kind of activity and the specific, overt process of marketing. This difference has been particularly apparent in attempts of public utilities to “sell” nuclear power plants. Utilities, of course, are monopoly suppliers and, as such, must seek a favorable image in the community. Thus, when public opposition to nuclear power plants mounted, many utilities responded with stepped-up public relations programs; the method they knew best. This article examines the experience of several utilities in locating nuclear plants and suggests how marketing techniques might be used in selling this intangible product.     

椭圆上特殊点的准确作图原理简析

画法几何中用八点法作椭圆时,一般是根据圆的外切四边形画出平行四边形,从而确定两对特殊的共轭直径,所画椭圆的8个特殊点中总有4个点可以比较直观地确定,而其余4个点只能近似地在相应的共轭直径上求出。本文应用仿射对应等方法,阐述了准确定出椭圆周必定经过的特殊点的位置,并提出其作图的理论根据,同时提供了多种准确快速地确定这些特殊点的方法。     

The use of open source internet to analysis and predict stock market trading volume

The objective of this paper is to evaluate the impact of information demand and supply on stock market trading volume. Few studies have demonstrated the role of Google search data in analyzing trading volume activity. In this study, we employ a proxy for information demand which is derived from weekly internet search volume. The latest is from Google Trends database, for 25 of the largest stocks traded on CAC40 index, between April 2007 and March 2014. We use news headlines as a proxy for information supply. We use Garch model to analyze and predict trading volume.The empirical results present new evidences. First, information supply has an impact on trading volume but information demand's impact is much more important. Secondly, by applying MCA to results found, it could be concluded that the impact of public information on transaction volume is conditioned by two elements: the firm and market news disclosure and the second element relates to the characteristics of the market participants, more precisely their news interpretations and their risk aversion. Thirdly, we used Chow structural break test to verify the stability of our model. We found that for securities with structural changes, information demand is the responsible variable of the change in our model. Finally, we found that information variables have a predictive power on transaction volume.This paper contributes to existing literature by incorporating open source internet-based data into the analysis and prediction of transaction volume. Using internet information about the stock market, which has appeared recently as an interesting research for financial empiricists, computer scientists and practitioners, will have a very important utility because quantifying demand and supply of information becomes possible.     

A characterization of the extended serial correspondence

We study the problem of assigning objects to a group of agents. We focus on probabilistic methods that take agents’ ordinal preferences over the objects. Importantly, we allow for indifferences among objects. Katta and Sethuraman (2006) propose the extended serial correspondence to solve this problem. Our main result is a characterization of the extended serial correspondence in welfare terms by means of stochastic dominance efficiency, stochastic dominance no-envy and “limited invariance,” a requirement we adapt from Heo (2014a). We also prove that an assignment matrix is selected by the extended serial correspondence if and only if it satisfies “non-wastefulness” and “ordinal fairness,” which we adapt from Kesten et al. (2011).

客户偏好指标和银行渠道使用对应分析研究

随着商业银行竞争的日趋激烈,银行营销渠道在其经营发展中地位日益明显。由于不同渠道其服务范围和条件、成本和效益有明显的区别,同时,客户不同的行为偏好对于不同渠道的应用也存在差异,所以,商业银行客户偏好分析就成为银行渠道发展策略的首要任务和出发点。在介绍相关理论基础上,建立商业银行客户偏好分析的框架,提出了客户偏好分析指标体系,最终利用实际调研数据对客户偏好指标和银行渠道进行分析,得到偏好指标和渠道之间的对应关系,对国内商业银行如何利用客户偏好分析方法实施差异化策略提出方法和建议。     

企业物流服务组织模式与决策动因的对应分析

企业物流服务组织中的主要模式一般包括物流外包、物流自营以及部分外包部分自营。在现实中,由于受到复杂主、客观环境因素的影响,企业在进行物流服务模式的选择时必须考虑诸多因素,以形成合理的、具有针对性的决策方案。因此,研究企业物流服务组织模式与决策动因之间的关系非常重要。本文通过对物流服务需求方实体企业的抽样调查分析,从企业所在系统和环境因素入手来挖掘企业决定其物流组织模式的主要动因,运用对应分析方法对不同物流服务模式与决策动因之间的关系进行研究,从而为企业的物流决策行为提供借鉴。
