组织支持感与员工创造力——相对组织支持感和情感承诺的影响

从自我提升视角出发，基于社会比较理论与社会交换理论，分析组织支持感影响员工创造力的过程机制，相对组织支持感的调节作用以及情感承诺与创造力之间的曲线关系。基于458份企业员工与主管的配对样本，研究结果表明：相对组织支持感显著正向调节了组织支持感与情感承诺之间的关系，情感承诺与员工创造力呈显著的倒U型关系，情感承诺在组织支持感与创造力关系之间起到了瞬时中介作用。研究结果拓展了对组织支持感的影响机制及其边界条件的分析，深化了情感承诺与员工创造力关系的检验。     

Krazy Kimmy's: A Case in Fraud Examination

This two‐part case allows for maximum student engagement through preparation, in‐class discussion, and through a Part B case that is part of the Teaching Note. Through this case, students work to identify possible fraud schemes, plan an investigation, and perform horizontal analysis calculations. Students will learn about the concept of ethical hacking, red flag identification, internal control weaknesses, and investigation considerations for fraud schemes. Further, in‐class planning for next steps and investigation can occur, providing an opportunity for group work and in‐depth learning. This case offers flexibility for instructors in that it can be covered over one class or multiple classes, or can be assigned as an independent or group assignment. This teaching note provides an overview of the case along with guidance for teaching this case.     

Relative risk aversion, relative prudence and comparative statics under uncertainty: The case of (μ, σ)‐preferences

From the expected‐utility approach, relative risk aversion being smaller than one and relative prudence being smaller than two emerge as preference restrictions that fully determine the optimal responses of decisions under uncertainty to certain shifts in probability distributions. We characterize the magnitudes of relative risk aversion and relative prudence in terms of the two‐parameter, mean‐standard deviation approach. We demonstrate that this characterization is instrumental in obtaining comparative static results in the two‐parameter setting. We further relate our findings to the results in the expected‐utility framework.     

Keeping Up with the Joneses and the Home Bias

We argue that when individuals care about their consumption relative to that of their neighbours, a home bias emerges, that is investors overweight domestic stocks in their portfolios. Domestic stocks are preferred because they also serve the objective of mimicking the economic fortunes and welfare of the investor's neighbours, countrymen, and social reference group. We also demonstrate that globalization mitigates the home bias, and derive a modified international CAPM.     

Why are Small Firms Different? Managers’ Views

Do incentives differ between large and small organizations? Results from a representative survey of compensation managers are used to shed light on the issues. I find that (i) small establishments rely less on pecuniary incentives, and have a significantly more hostile attitude towards incentive schemes based on competition and relative rewards; (ii) large units are more vulnerable to mechanisms of efficiency wages, effects that remain even after controlling for differences in monitoring ability; (iii) large units are more prone to indicate that negative reciprocity is important, and that their employees care about relative pay. I argue that these findings fit with behavioral stories of incentives and motivation, in particular those stressing group interaction effects, inequity aversion and gift exchange.     

Comparing the True Cost of Living Indices of Demographically Different Households

The comparison of true cost of living indices between demographically different households (relative equivalence scale) is argued to be sensitive to the way demographic characteristics enter demand analysis. In particular, parameters reflecting the cost of demographic characteristics at base prices, though themselves do not have welfare (equivalence scale) interpretation, can alter the benchmark from which demographically varying inflation effects are measured. The empirical analysis, based on a rank‐3 demand system applied to UK individual household data, shows that the inflation adjustment of child benefits can vary with the way demographic costs at base period prices are specified.     

如何看待我国民营上市公司EVA与MVA的反差问题

通过对2001年EVA与MVA反差最大的20家民营企业的统计数据进行了相关分析与因子分析,提出使用第一主成分作为投机炒作的度量,弟二主成分反映了股本与业绩的背离程度,并对2001年EVA与MVA反差最大的20家企业进行分析并排序。     

数据包络分析有效性理论的一点探索

文章给出经典的基于输入的和基于输出的数据包络分析(DEA)模型,以及把基于输入和基于输出的模型相结合的相对效率模型,并且把这些模型引用到评价证券的相对有效性上,以风险作为输入,期望收益率作为输出,便可以用DEA模型评价每只证券的相对有效性.     

大城市边缘区土地利用变化与社会经济发展关系分析——以北京市平谷区为例

大城市边缘区是城市化最敏感、变化最大、最迅速的地区,也是土地利用变化最显著的地区,研究大城市边缘区土地利用变化时空过程及其驱动机制,对实现大城市自身可持续发展具有重要意义。该文采用数理统计与综合分析方法,对北京市平谷区土地利用动态变化及其与GDP、产业结构、消费结构、城镇化以及人口等社会经济发展因素的关系进行了分析。研究结果表明:1996~2004年,平谷区农用地面积持续减少,其中耕地减少较多,园地增长速度较快,林地略有减少。建设用地持续增加,其中交通用地增长速度最快。平谷区的土地利用变化与经济增长、产业升级、城镇化发展、消费结构变化以及人口增长具有显著的相关性,社会经济发展是土地利用变化的主要驱动因素。节约集约土地,提高土地利用效率,调整土地利用结构,促进产业优化升级,保障服务首都北京功能和平谷区域社会经济发展成为平谷区土地利用的必然要求。     

基于AHP＋熵组合的相对发达地区新乡镇建设评价——以苏南三镇为例

面对新农村建设活跃和城市化进程加速，新乡镇建设也初见端倪，选取苏南三镇作为实证地点，构建相对发达地区新乡镇建设评价体系，利用主观赋权的层次分析法（AHP）和客观赋权的熵权法进行组合评价。
