Ambiguity of measured WTP for quality improvements when quantity is unconstrained: a note

This paper addresses the issue of how to estimate by contingentvaluation methods the maximum price consumers are willing topay when a new quality is available for a market good for whichquantity adjustments are possible. We argue that current practice,which typically does not specify a quantity when asking consumersthe price they are willing to pay for a new quality product,fails to identify prospective consumers' behaviour when theyare free to adjust the quantity purchased. Theoretical modelsare discussed for assessing the maximum price consumers arewilling to pay in these cases, and econometric approaches toaddress these situations are discussed.     

价值溢价与一月效应——来自上海A股市场的经验证据

以2000年1月至2011年12月沪市A股上市公司为样本,按Size-B/M方法构建6投资组合,考察我国股市的价值溢价是否存在一月效应现象,检验大盘股、小盘股价值溢价在1月和非1月是否不同,并采用CAPM模型检验价值溢价的一月效应。实证结果发现:1)采用账面市值比B/M划分成长-价值型股票组合,大盘股和小盘股股票都存在价值溢价;2)大盘股和小盘股的价值溢价在1月与非1月存在不同的模式——大盘股在1月存在显著的价值溢价,而小盘股的价值溢价主要在非1月的月份出现;3)CAPM模型能够解释我国股市从2007年1月至2011年12月期间的价值溢价。相对小盘股,大盘股的价值溢价的一月效应更为显著。     

我国地方政府信用评估研究

地方政府公信力是衡量政府信用状况和信用程度的重要概念。当前,我国地方政府公信力从总体上来说正在逐步提高,但也有部分地区呈现出弱化趋势。近年来,更是曝出了"华南虎事件"、"毒奶粉事件"等一大批丑闻。对地方政府信用进行评估,既是投资者进行投资决策分析的需要,也是对地区竞争力进行客观分析的需要,同时也是地方政府认识和改进自身信用状况的需要。本文在分析了我国地方政府公信力现状的基础上构建了地方政府公信力评估体系,并以河南省Z市为例,通过对地方政府公信力的评估,为提高我国地方政府公信力提出了相关建议。     

盈余信息风险的权益风险溢价研究——基于中国上市公司财务数据

盈余信息是公司金融与投资决策的主要依据之一。以三因素定价模型、流动性定价模型和多因素定价模型为比较检验基准模型,利用中国上市公司财务数据,本文探讨了总应计和线上项目的盈余信息风险对权益风险溢价是否具有显著的增量解释能力。研究表明,权益风险报酬对总应计利润信息风险的因素载荷为正,其反应比较显著;权益风险报酬对线上项目利润信息风险的因素载荷也为正,但是其反应程度不太显著。在综合考虑多种风险因素的情况下,总应计利润信息风险的因素载荷较大。     

慈善组织监管与慈善组织公信力重塑路径研究综述

公信力是慈善组织的灵魂,但当前国内慈善组织的丑闻事件层出,不仅沉重打击了慈善组织在公众心中的神圣形象,而且在一定程度上严重影响了慈善组织的长远发展。因此,对慈善组织的公信力流失问题进行研究,具有重要的理论和实践意义。综合国内外学者的观点,其研究的重点集中在慈善组织公信力的内涵、公信力流失的原因、公信力评估及公信力的重塑路径4个方面。这些研究为我们反思慈善组织公信力流失现象以及加强监管、重塑慈善组织的公众形象提供了很好的学术基础。     

The risk–return relation in the corporate loan market

This paper analyzes the hypothesis that returns play a risk-compensating role in the market for corporate revolving lines of credit. Specifically, we test whether borrower risk and the expected return on these debt instruments are positively related. Our main findings support this prediction, in contrast to the only previous work that examined this problem two decades ago. Nevertheless, we find evidence of mispricing regarding the risk of deteriorating firms using their facilities more intensively and during the subprime crisis.     

Auditors' Fee Premiums and Low‐Quality Internal Controls*

We examine the relation between low‐quality internal controls and audit fee premiums. Using a novel data set of audit hours and audit fees we find, consistent with the audit risk model, that auditors increase their effort (hours) owing to low internal control quality. We find that auditors also charge a significant fee premium to clients with internal control weaknesses. This premium is observed for severe internal control weaknesses and companies with low‐quality alternative governance mechanisms. The results are robust to multiple methods to address endogeneity, including company fixed effects, difference‐in‐differences design, and a propensity score‐matched sample. Taken as a whole, low internal control quality leads to fee premiums, which are a deadweight loss to client companies.     

微信运动健康因子对健康保险费率影响研究

近年来,微信运动促进群众的运动风潮不断上涨。然而查询已有文献,较少提及微信运动使用与健康保险费率的关系。借由因素萃取、逻吉斯回归、均值检定等方式研究发现,微信健康计步功能使用时间越长的消费者,其住院概率较低（P<0.1）,健康保险费率也显著低于不使用微信健康计步功能的消费者（P<0.01）。因此,建议在合法的情况下,进行认识客户工作,采集的数据可作为健康保险订定差异费率的参考。     

Factors influencing applicant willingness to apply for the advertised job opening: the mediational role of credibility,satisfaction and attraction

The present study examined the effects of the information given in a job advertisement on the potential applicants' willingness to apply for the job opening with the mediating roles of credibility of and satisfaction from the information given in the ad and attraction to the organization. One hundred and fifty-four students were randomly assigned to the three different versions of job advertisement. Additionally, a questionnaire package was given to each participant. The results showed that advertisement type affected the willingness of potential applicants to apply for the job and this relationship was mediated by credibility.
