浅析电子商务市场中的信任机制——基于“柠檬市场”理论的分析

通常认为,互联网的出现有利于消除消费者的信息劣势,但事实是,电子商务市场的“柠檬”问题却因为网络的虚拟性实际上被强化了,它可能会降低人们对网络交易的信任感。为此,如何解决这些问题就需要我们进行深入的探讨。本文以“柠檬市场”理论为出发点,分析了信任缺乏的内在机理,并结合案例分析提出了建立网络信任的策略思路。

井冈山风景区公路网络整体可达性分析

运用可达性方法定量研究井冈山风景区公路网络空间结构,考虑地形、道路等级、拥挤度等因素对车速的影响,采用加权平均旅行时间评价指标,分析不同旅游季节景点可达性和对外可达性变化。研究表明:1井冈山风景区景点可达性和对外可达性分别呈现"中心—外围"摄动变形的圈层结构与"东—西"摄动变形的圈层结构,可达性空间分布遵循空间距离衰减性、交通指向性、高等级路网指向性等。2旅游季节因素对可达性影响显著,旅游旺季可达性水平发生明显变化,可达性空间分布也受其影响。3路网结构、景点布局和节点规模是影响可达性分布的重要因子。在此基础上,提出了可达性优化建议。     

Performance of Foreign and Global Mutual Funds: The Role of Security Selection,Region‐Shifting,and Style‐Shifting Abilities

We examine the performance of U.S.‐based foreign and global funds after controlling for their regional and style exposure. We show that, on average, the total performance (TP) and security selection abilities of both foreign and global funds are significantly negative and exhibit short‐term predictability. Additionally, R² reflects funds’ security selection abilities, consistent with previous findings for domestic mutual funds. Investors can earn higher abnormal returns and TP in the short run by purchasing past winners with low R² than by purchasing past losers with high R². However, there is no evidence of predictability in the funds' region‐shifting and style‐shifting abilities.     

Foreign Institutional Ownership and the Global Convergence of Financial Reporting Practices

This paper investigates whether foreign institutional investors affect the global convergence of financial reporting practices. Using several measures of reporting convergence, we show that U.S. institutional ownership is positively associated with subsequent changes in emerging market firms’ accounting comparability to their U.S. industry peers. We identify this association using an instrumental variable approach that exploits exogenous variation in U.S. institutional investment generated by the JGTRRA Act of 2003. Further, we provide evidence of a specific mechanism—the switch to a Big Four audit firm—through which U.S. institutional investors affect reporting convergence. Finally, we show that, for emerging market firms, an increase in comparability to U.S. firms is associated with an improvement in the properties of foreign analysts’ forecasts.     

Financial density selection

We propose and study simple but flexible methods for density selection of skewed versions of the two most popular density classes in finance, the exponential power distribution and the t distribution. For the first type of method, which simply consists of selecting a density by means of an information criterion, the Schwarz criterion stands out since it performs well across density categories, and in particular when the DGP is normal. For the second type of method, general-to-specific density selection, the simulations suggest that it can improve the recovery rate in predictable ways by changing the significance level. This is useful because it enables us to increase (reduce) the recovery rate of non-normal densities by increasing (reducing) the significance level, if one wishes to do so. The third type of method is a generalisation of the second type, such that it can be applied across an arbitrary number of density classes, nested or non-nested. Finally, the methods are illustrated in an empirical application.     

独董与其他高管的公司治理作用有差异吗？——基于政治关联与审计契约视角的检验

以2007—2011年A股非金融保险业上市公司为样本,从政治关联与审计契约角度揭示独立董事与其他高管在公司治理中的差异。研究发现:在审计师选择方面,独立董事存在政治关联的企业倾向于选择高质量的审计服务,其他高管存在政治关联的企业倾向于选择低质量的审计服务。结合对审计费用考察发现,其他高管存在政治关联的企业选择较低质量审计服务的同时却支付相对较高的审计费用,但又并没有支付显著高于独立董事存在政治关联的企业选择高质量审计服务时支付的审计费用。     

格列苯脲有关物质检查中色谱柱的选择

高效液相色谱法作为含量测定和有关杂质检查的方法被越来越多地应用于各国药品标准中,色谱柱是高效液相色谱法的关键,但由于色谱柱种类繁多以及选择性的差异,导致药典在执行过程中很难保证检查方法的重现性,因此选择合适的色谱柱成为色谱分析的关键。以降糖药格列苯脲有关物质检查中色谱柱的选择为例,参照欧洲药典(EP7.0),对给出的5种色谱柱分别按照不同的分类方法进行分类,对5种色谱柱有关物质检查系统的适用性分别进行测试。根据测试结果得出的结论,分析比较了不同色谱柱分类方法对色谱柱选择所起的作用。分析结果表明,结合不同的色谱柱分类方法对色谱柱进行选择,可以选出适用的色谱柱。
