项目进度绩效指标的改进及其动态性预测

传统的挣值方法中,进度指标的预测多表现单期、静态的特性,存在严重的局限性。为了改进和完善挣值管理方法中进度指标体系,在考虑时间序列的基础上,将统计方法引入挣值管理进度指标体系中,用更加科学的方法对项目进度指标进行描述,并在此基础上基于贝叶斯推断方法,加入专家意见,从统计学的角度提出了进度绩效指数的动态预测模型,因而,可以为项目管理者提供科学的据侧依据。

Accounting data and the credit spread: An empirical investigation

Measures of credit risk based on Merton (1974) rely upon information available in the market prices of securities. Under the Efficient Market Hypothesis market prices should reflect all available information and, hence, make redundant all other information in the analysis of credit risk. This paper examines whether accounting data are fully reflected in the market-based measures of credit risk and therefore has no role in explaining variations in the credit spread on corporate bonds. We use a sample consisting of over 11,000 firm-quarter observations with matched equity, bond and accounting data. The results suggest that equity volatility and Merton's distance-to-default outperform accounting variables in explaining variations in the credit spread. However, accounting variables are incrementally informative in explaining variations in the credit spread when considered in conjunction with market-based measures. Within the set of accounting variables considered, we find that the profitability ratio is by far the most incrementally informative accounting variable.     

EVA及其对我国上市公司的意义

EVA是经济增加值的简称 ,是经过调整后的税后营业净利润扣除全部资金成本后的余额。EVA考虑了包括股权资金在内的全部资金的成本 ,体现了企业在某个时期创造或毁坏的价值量。与会计利润相比 ,EVA易于理解且不易被操纵 ,根据其所设计的“奖金银行”是一种有效的激励机制 ,并且向企业提供了一个单一的、协调的目标 ,避免了多目标的混乱。EVA指标对当前我国的上市公司具有特别突出的意义 ,应用EVA来评价上市公司有利于规范我国上市公司的融资行为、投资行为和股利分配行为 ,并约束上市公司的“内部人控制”。应加快研究适合我国国情和上市公司实际的EVA计算方法 ,把EVA作为我国上市公司业绩评价和相关部门制订政策时的参考指标之一。     

Understanding customers’ healthy food choices at casual dining restaurants: Using the Value–Attitude–Behavior model

This study examined how individual health values influence interest in healthy foods, positive outcome expectations, hedonic expectations, and behavior intentions. A total of 1188 valid questionnaires were collected from customers who had consumed healthy menu items at casual dining restaurants. The results indicated that health value was the key element that inspired customer interest in healthy eating and aroused hedonic and positive outcome expectations, which in turn enhanced intentions to purchase healthy food items. Restaurant managers are advised to establish creative marketing strategies to motivate customer interest in healthy menu items and emphasize benefits of their healthy food items. Future studies can extend the scope of research by examining differences in geographical areas or demographic profiles.     

中国银行业创值能力分析--EVA体系对银行经营绩效的考察

中国经济要保持高速、稳定增长,需要进一步提高经济效率,实现质量型增长.其中,关键是资金效率.中国资金运用效率的高低很大程度上取决于占社会资金78%以上的银行业的资金效率.为此,本文应用EVA分析体系来综合系统地分析中国银行业的绩效.分析结果显示,上市银行虽然好于非上市银行,但由于国有商业银行的比重较大,银行业整体创值能力明显较弱.建议以提高国有商业银行资金运用效率为当下改进社会资金运用效率的切入口.

Making effective pricing decisions

Pricing is one of the most complex decisions facing any company. Along with a lack of academic interest (especially among marketing academics) in the field of pricing, this complexity has contributed to the dominance of simplified, cost-based formulas when levying prices. This article offers an alternative approach based on the concept of contribution margin and the need to take into consideration only those costs that are related directly to a specific pricing decision, an approach that is especially useful when a company decides to change its prices. Moreover, an empirical study regarding the practical use of this approach is also presented.
