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.

低房价房地产开发项目桩基方案优化价值分析

软土地区低房价商品房的开发可行性,很大程度上取决于桩基设计方案。文中以一个小高层商品房的桩基方案优选为对象,基于价值分析法,在桩基工程功能和成本分析的基础上,提出桩基设计方案的价值评价指标,并用于该项目评价,结果与传统对比分析法一致。表明:1)价值分析法适用于桩基方案优选,而且与传统的对比分析法相比,用定量的数据说话,更准确、科学;2)所提出的价值评价指标对该项目是正确适用的。此外,还对该工程其它的桩基设计方案以及价值评价指标的通用公式进行了简要探讨,供进一步研究和同类工程参考。     

对欠发达地区货币传导扭曲的实证分析

我国货币政策对生产活动的影响主要通过银行贷款渠道.1997年央行从松货币政策的措施实施以来,全国与西北贷款规模相对差异的拉大、投资规模相对差异的缩小及资本形成率差异增大.本文以银行贷款渠道为例对西北地区货币政策传导进行分析,得出货币政策效果差异的直接原因是特定的基础货币投放机制和西北地区过度的信贷萎缩,根本原因在于西北地区经济基础差,投资收益率低,商业银行机构撒并和信贷策略调整,民间投资不足等因素.
