金融资产规模、公允价值会计 与管理层过度自信

本文以2004-2009年持有证券资产的A股上市公司为样本，对金融资产规模的决定因素进行了理论和实证研究，得到以下研究结论：（1）公允价值会计是上市公司金融资产规模显著增加的解释因素；（2）管理层过度自信在成本计量模式下与金融资产规模只有弱相关性，但在公允价值会计下却与金融资产规模显著正相关；（3）受政府控制的公司、大股东持股比例高的公司在成本计量模式下有显著更低的金融资产规模，但在公允价值会计下，特别是当管理层过度自信时，金融资产规模却呈现为显著增加。上述结论解释了会计理念、管理层行为与金融风险的内在关联性：公允价值计量模式遵循的是价值相关性原则，要求把证券持有利得也计入资产价值和会计收益，这个未来价值理念激励了公司管理层和控股股东的金融投资行为。

企业社会责任对消费者满意度的影响——基于国产乳制品行业的实证分析

基于消费者视角，对企业社会行为与消费者满意度的内在影响机制进行了研究，研究企业声誉、感知质量和感知价值在两者之间的作用。以国产乳制品行业为例构建了企业社会责任-消费者满意度模型，并进行实证分析。结果表明：企业社会责任对消费者满意度呈现显著的正向影响；企业社会责任对企业声誉存在显著的正向影响；企业社会责任、企业声誉对感知质量均存在显著的正向影响；企业社会责任、企业声誉、感知质量对感知价值有显著的正向影响；感知价值对消费者满意度存在显著的正向影响。企业社会责任除了直接作用于消费者满意度外，还能够通过企业声誉等变量间接地对消费者满意度产生影响。

Bank loan announcements and borrower stock returns before and during the recent financial crisis

The impact of U.S. bank loan announcements on the stock prices of the corporate borrowers has been decreasing during the two last decades with estimated two-day cumulative abnormal returns slipping from almost 200 basis points in the beginning of the 1980s to close to zero by the turn of the Century. We estimate excess returns before and after the onset of the most recent financial crisis. We find that while prior to August 2007 returns were indeed close to zero, afterwards returns jump back up to around 200 basis points. We surmise that in a booming credit market the certification of corporate borrowers by banks started to play a lesser role, while during the crisis the banks’ role was revitalized. Consistent with this interpretation we find that after August 2007 excess returns increase especially for loans with a longer maturity, and for smaller, levered, less profitable or lowly rated firms.

On Conformity Testing and the Use of two Stage Procedures

Conformity testing is a systematic examination of the extent to which an entity conforms to specified requirements. Such testing is performed in industry as well as in regulatory agencies in a variety of fields. In this paper we discuss conformity testing under measurement or sampling uncertainty. Although the situation has many analogies to statistical testing of a hypothesis concerning the unknown value of the measurand there are no generally accepted rules for handling measurement uncertainty when testing for conformity. Usually the objective of a test for conformity is to provide assurance of conformity. We therefore suggest that an appropriate statistical test for conformity should be devised such that there is only a small probability of declaring conformity when in fact the entity does not conform. An operational way of formulating this principle is to require that whenever an entity has been declared to be conforming, it should not be possible to alter that declaration, even if the entity was investigated with better (more precise) measuring instruments, or measurement procedures. Some industries and agencies designate specification limits under consideration of the measurement uncertainty. This practice is not invariant under changes of measurement procedure. We therefore suggest that conformity testing should be based upon a comparison of a confidence interval for the value of the measurand with some limiting values that have been designated without regard to the measurement uncertainty. Such a procedure is in line with the recently established practice of reporting measurement uncertainty as “an interval of values that could reasonably be attributed to the measurand”. The price to be paid for a reliable assurance of conformity is a relatively large risk that the procedure will fail to establish conformity for entities that only marginally conform. We suggest a two‐stage procedure that may improve this situation and provide a better discriminatory ability. In an example we illustrate the determination of the power function of such a two‐stage procedure.
