延迟退休年龄政策平稳推进路径研究——以江苏省为例

基于江苏省调研资料和数据分析,从理解性、制度性、技术性等层面分析研究退休政策平稳推进过程中面临的问题。由于民众对延退理解误区,普遍存有抵触心理;加之养老保险制度公平缺失,就业制度不完善,家庭扶持政策不足;同时养老保险的技术性问题层出不穷,高缴费水平、待遇计发办法与调整办法不合理,加剧改革难度。于此,我国延迟退休年龄需要在消除民众认识误区基础上,了解改革的现实需要,着力解决相关制度和技术存在的问题,选择适合我国国情和社会环境的延迟退休年龄改革路径。     

Management earnings forecasts and the quality of analysts’ forecasts: The moderating effect of audit committees

This study investigates whether effective audit committees influence the association between management earnings forecasts and the properties of analysts’ forecasts. We posit that this influence on the part of an audit committee would likely result from increased responsibility for monitoring voluntary disclosure. Using the four attributes that the Blue Ribbon Committee (1999) and prior research suggest as being indicative of audit committee effectiveness, we find that analysts’ forecasts exhibit higher accuracy and lower dispersion with the issuance of management forecasts for those firms employing audit committees that are composed exclusively of independent directors, include an accounting expert, and act with due diligence. We also find that effective audit committees strengthen the association between management and analyst forecast accuracy. Our evidence, therefore, supports the notion that effective corporate governance influences the reliability of voluntary disclosure, and thereby benefits the users of financial information.     

基尼系数和中等收入群体比重的关联性分析

基尼系数是测量和判断收入分配状况最常用的综合指标之一,而中等收入群体比重则是判断社会稳定与否的重要标志。本文通过重新定义低、中、高三类收入群体以及采用多项式函数形式拟合洛伦兹曲线,建立基尼系数和中等收入群体比重之间的数量对应关系。实证分析表明:基尼系数和中等收入比重之间存在负向相关关系。2001年中国的基尼系数约为0．44,相应的中等收入群体比重大致在44%左右。     

Perceptual difference of dependence and its impact on conflict in marketing channels in China: An empirical study with two-sided data

Although many firms have adopted the relational exchange or relationship marketing philosophy for developing long-term inter-firm relationships in marketing channels, the issues pertaining to channel conflict still deserve further investigation. The purpose of this paper is to examine the possible impact of perceptual difference of dependence between members in channel dyads on perceived channel conflict. By analyzing paired data collected from both sides of supplier-retailer dyads in China, we test two hypotheses about perceptual difference of dependence and its impact on conflict. We found that there was considerable perceptual difference of dependence between both sides of the dyads, and that the perceptual difference of dependence asymmetry between the two was positively associated with channel conflict perceived by the supplier side. Both researchers and practitioners should be aware of such differences when confronted with channel conflict issues, especially in international channel settings.

Optimal insurance under rank‐dependent utility and incentive compatibility

Bernard, He, Yan, and Zhou (Mathematical Finance, 25(1), 154–186) studied an optimal insurance design problem where an individual's preference is of the rank‐dependent utility (RDU) type, and show that in general an optimal contract covers both large and small losses. However, their results suffer from the unrealistic assumption that the random loss has no atom, as well as a problem of moral hazard that provides incentives for the insured to falsely report the actual loss. This paper addresses these setbacks by removing the nonatomic assumption, and by exogenously imposing the “incentive compatibility” constraint that both indemnity function and insured's retention function are increasing with respect to the loss. We characterize the optimal solutions via calculus of variations, and then apply the result to obtain explicitly expressed contracts for problems with Yaari's dual criterion and general RDU. Finally, we use numerical examples to compare the results between ours and Bernard et al.     

基于电子鼻技术对调味品中非法添加罂粟壳的检测

采用便携式PEN3电子鼻检测调味品中非法添加罂粟壳。分别对非法添加有不同比例罂粟壳的花椒粉、孜然粉、烧烤粉进行辨别,用线性判别式(LDA)与多层感知器(MLP)两种方法对数据进行分析。结果表明:电子鼻能够较好的识别调味品中非法添加不同比例的罂粟壳,多层感知器相较于线性判别具有更好的区分效果,并且对未知样品进行准确预测。

中国服务业吸引FDI的影响因素研究——基于省际面板数据的实证检验

本文在对服务业吸引FDI的内在机制进行深入分析的基础上,构建一个计量模型对中国服务业吸引FDI的影响因素进行实证研究。研究表明,促进我国服务业吸引FDI的有利因素是地区人力资本水平、地区法制水平、服务业发展水平、劳动力市场化程度,阻碍服务业吸引FDI的不利因素是政府对地方经济干预程度过深。
