Decision theoretic estimation using record statistics

We consider the problem of estimating the scale parameter θ of the shifted exponential distribution with unknown shift based on a set of observed records drawn from a sequential sample of independent and identically distributed random variables. Under a large class of bowl-shaped loss functions, the best affine equivariant estimator (BAEE) of θ is shown to be inadmissible. Two dominating procedures are proposed. A numerical study is performed to show the extent of risk reduction that the improved estimators provide over the BAEE.     

诚信在超市经营管理中的价值研究

本研究利用结构方程模型验证了超市诚信对顾客感知价值、顾客满意度、顾客忠诚度的影响机制。经过模型修正与复合效化两个过程,最终获得了一个与数据拟合度比较高的模型:(1)超市诚信→顾客感知价值→顾客忠诚;(2)超市诚信→顾客感知价值→顾客满意。即超市诚信通过影响顾客感知价值来分别影响顾客满意和顾客忠诚,顾客满意与顾客忠诚之间的相互影响不显著。     

基于VaR模型对我国外汇储备规模适度性的研究

本文根据外汇储备的用途,建立了一个关于固定汇率制度下一国外汇储备规模的需求模型,在此基础上结合模型提出了建立我国外汇储备适度规模的估计方法,并进行了举例说明,从中可以发现模型对提高我国外汇储备规模的管理水平是有益的。     

物流配送中心规模设计方法研究

物流配送中心是进行货物流通的场所,为合理利用城市土地资源,必须对物流配送中心的规模进行优化设计。根据规模设计的原则和配送中心的业务量、性质及远期发展等,对物流配送中心规模进行细化,分别进行量化计算,从而达到优化设计的目的。     

“一带一路”沿线国家外债风险评价及启示——基于31个沿线国家的数据分析

"一带一路"沿线国家的外债风险对中国企业境外投资的经济效益和社会效应都有重要影响。本文以负债率、偿债率和债务率指标为基础构建了外债风险评价指标体系,选取"一带一路"沿线31个国家2010年-2017年的数据,运用模糊物元分析法综合测度沿线国家的外债风险,并进行成因分析。研究结果表明:"一带一路"沿线国家外债风险总体呈上升趋势;蒙古、老挝、斯里兰卡、乌克兰、哈萨克斯坦、巴基斯坦和吉尔吉斯斯坦等国家的外债风险非常高;财政赤字、贸易条件恶化、国际市场利率提高是推动沿线国家外债风险上升的最主要原因。为提升中国企业对沿线国家直接投资的质量和效益,中国企业应优化直接投资的空间布局,减少对高外债风险国家的投资;拓宽投资领域,增加非能源领域的投资,带动沿线国家经济增长和就业;投资前应严格审核项目,合理融资方式,避免增加债务风险。     

我国中小企业的规模效率与融资困境

我国大多数中小企业由于资金数量的限制，难以达到规模效率的要求，同时，中小企业还面临着内源融资短缺和外部融资难的问题。解决中小企业融资问题需要从强化内源融资、税收优惠、财政补贴、建立中小企业融资担保体系和提高中小企业自身素质等几个方面做出努力。     

组织支持感对员工知识共享行为的影响：自我效能的中介效应

员工知识共享行为能够促进知识在组织边界内产生溢出效应,从强化内部动机的视角引入自我效能分析组织支持感与员工知识共享行为之间的关系,并构建概念模型进行实证研究具有重要的理论价值。实证结果表明：组织支持感的三个维度中工作支持、价值认同对员工的知识获取行为和知识贡献行为都具有显著的正向影响,关心利益只对员工的知识获取行为具有显著正向影响;自我效能在工作支持、价值认同与知识贡献之间和在价值认同与知识获取之间起到完全中介作用,在工作支持与知识获取之间起到部分中介作用。     

The Signaling Impact of Low Introductory Price on Perceived Quality and Trial

Economic signaling theory suggests that consumers interpret price withinthe context of market conditions. Under specific conditions it predicts thatlow price may signal high quality. Results from an experiment designed totest the behavioral assumptions underlying this prediction indicate thatconsumers intentions to purchase conform to the predictions of economicsignaling theory, but their judgments of product quality do not. The resultssuggest that consumers' response to signals may be more complex thanpreviously shown.     

Anticipating a service experience

This paper explores the anticipations consumers have before service experiences. Consumers think ahead about future service experiences and may foresee problems or discomfort. This research examines the strategies consumers engage in to minimize the impact of these anticipated problems or discomforts. Qualitative interviews and the critical incident technique with a content analysis provide the tools of this study. In Study 1, planning and preparation, avoidance and adjustment, and seeking support emerge as three problem-solving behaviors. In Study 2, the same three problem-solving behaviors emerge, while a fourth category, gathering information, also appears. In addition, worry, as an emotional response to perceived risk, provides understanding to service anticipation issues. Social risk plays a particularly important role as well.     

Sponsorship portfolio as a brand-image creation strategy

The meanings held by events are sometimes transferable to a brand through sponsorship. The perceived sponsor-property fit affects brand evaluations. This research hypothesizes that in the case of a sponsorship portfolio, the source of image transfer can be composite, and brand image association may depend on the perceived fit between sponsorships. Building on theories of social cognition and categorization, this research proposes two dimensions of fit: sponsorship category relatedness and event personality fit. Two experiments show that categorical relatedness between sponsorships not only leads to the creation of a unified brand personality for the sponsor, but also enhances brand meaning consistency and clarity. Central category-related traits cue a category membership framework that integrates sponsorships in the portfolio. Under conditions of category ambiguity, the impact of event personality fit emerges. Interestingly, the findings suggest that sponsored properties having a “spiky” brand personality (having both high and low performance on dimensions) may communicate most clearly in a portfolio.
