物流金融业务风险评价研究

建立了物流金融业务风险评价指标体系,使用模糊层次分析法(FAHP)进行风险评价.在传统的模型评价分析方法基础上,使用改进的AHP方法确定权值,通过专家对某物流金融业务进行打分得到关系矩阵.最后计算此业务的优良程度,并分析其风险的大小.

非对称信息下企业的物流外包服务商数量选择模型

探讨了外包过程中服务商数量变化与合同价格制定、服务质量以及对双方价值剩余的关系影响.模型在以往非对称信息下委托代理模型的研究基础上,加入了物流代理商个数参数作为激励约束条件,提出了代理商预期努力水平和实际服务质量两个行为指标.结果显示,给定环境系数,物流外包企业的价值总收入关于服务商数量的函数存在极大值,具有较优的服务代理商数量.同时服务努力水平及质量会随提供商数量的变化产生相应影响,在一定条件下随提供商数量的减少而提高.

Effects of Consumers’ Efforts on Price and Promotion Fairness Perceptions

This research examines how consumers’ efforts as a nonmonetary sacrifice influence their price and promotion fairness perceptions in the context of price promotions. Multiple studies using different price promotion tactics demonstrate that consumers’ perceived level of effort to obtain a reduced price negatively influences their fairness perceptions when they deny the promoted price. Exploring the underlying mechanisms of this effect, we show that the amount of effort consumers exert to obtain a promoted price leads to their feeling of deservingness and entitlement. When the promoted price is denied, this feeling of entitlement is violated, causing unfairness perceptions to occur. The research demonstrates that, in addition to retailers’ actions such as price changes, consumers’ actions, in the form of their effort input, are also an important determinant of fairness perceptions.     

Values,value types and moral reasoning of MBA students

This study uses the Schwartz Values Questionnaire and version 2 of the Defining Issues Test to investigate the values, value types (clusters of related values) and level of moral reasoning of a sample of 108 MBA students in a Canadian university. There are no statistically significant differences in the levels of moral reasoning attributed to gender. Male and female MBA students rank ‘family security’ and ‘healthy’ as their two most important values. For males, hedonism, achievement and self‐direction are the three most important value types, while for females they are benevolence, hedonism and security, respectively. There are statistically significant gender differences for the value types hedonism, achievement, stimulation and power. Overall, however, there are more similarities than differences between the male and the female students. Regression analysis indicates a statistically significant positive association between the postconventional level of moral reasoning as measured by P‐scores and the value‐type universalism. The findings provide further evidence that value types affect the postconventional level of moral reasoning.     

Implied and realized volatility: empirical model selection

The paper studies the nonparametric connection between realized and implied volatilities. No-arbitrage identities and comparison inequalities are found. We formulate the multi-factor trading system on the volatility scale. To empirically determine the number of factors, we develop a high frequency analysis for sequential F-testing. We also design a cross validated estimate of quadratic variation.     

Anonymity in Computer-Mediated Communication: More Contrarian Ideas with Less Influence

Anonymity is thought to be an important means for ensuring a free exchange of ideas by encouraging the expression of minority viewpoints. However, we suggest that anonymity’s reduction in awareness of others potentially affects the expression and interpretation of comments that are made during a discussion. In particular, anonymity will increase the likelihood that comments will be made that are contrary to the majority opinion while at the same time decreasing the effect that those contrary arguments have on other group member’s opinions. This paper reports experimental results showing that anonymity led to more overall participation in discussions of ethical scenarios. However, equality of member participation did not differ between anonymous and member-identified groups, and anonymous groups had significantly higher awareness-related comments. This leads to the conclusion that additional participation in anonymous groups accommodates reduced awareness rather than reflecting the increased participation of normally reticent group members. In addition, anonymity led to more arguments in support of questionable behavior, suggesting that the freeing effects of anonymity apply to the social desirability of arguments. Finally, there was less change in opinion under conditions of anonymity than when comments were identified, suggesting that anonymous arguments have less influence on opinions than identified comments.     

中国金融发展的空间非均衡与极化研究

以中国31个省份1978-2008年数据为样本,以金融相关比率为指标,对中国金融发展的空间非均衡特征与极化进行实证研究后发现:地理信息系统(GIS)的可视化方法,直观地表明了中国金融发展具有显著的空间非均衡特征;基尼系数测度及其分解表明,在样本考察期内,中国金融发展空间分布的总体差距呈现扩大趋势,其中地区间差距是中国金融发展地区差距的主要来源;金融发展极化程度测度结果表明,在样本考察期内,中国金融发展的空间极化程度呈现明显的递增趋势,组内聚合程度和组间对抗强度的不断上升成为金融发展极化程度上升的主要来源。     

基于低碳经济理念的兰州市产业结构调整对策分析

建设低碳城市,实现人口、资源、环境的可持续发展已经成为国际社会的普遍共识。兰州市产业结构不尽合理,第一产业中林业比重下降快;第二产业内部呈现出明显的重化工业特征,能源消费以煤为主,工业废物排放强度大;第三产业中传统服务业所占比重较大,易于造成环境污染。按照低碳经济的理念,需要调整农业产业结构以发挥自然生态系统的碳汇作用,积极开发新能源、新技术以发展低碳产业,进而实现兰州市产业结构的优化调整。
