Two standard‐setting approaches have emerged globally to guide the choice of accounting for securitizations: the control and components approach (SFAS No. 125 and SFAS No. 140) and the risks and rewards transfer approach (IAS No. 39). A lack of consensus about derecognition accounting is a major impediment to achieving convergence in global standards that must be resolved. Thus, both SFAS No. 140 and IAS No. 39 will be reexamined, and evidence pertinent to the debate is timely and important. In this study, we present evidence consistent with the view of credit‐rating analysts, who view many securitizations as, in substance, secured borrowings. Specifically, for a sample of originators applying sale accounting guidance in SFAS No. 125 / 140 during the period 1997‐2003, we show that off‐balance‐sheet debt related to securitizations has, on average, the same risk‐relevance for explaining market measures of risk (that is, CAPM beta) as on‐balance‐sheet debt. We also find that, in a returns and earnings association framework, the pricing multiple on securitization gains declines as the amount of off‐balance‐sheet debt increases, implying that investors take off‐balance‐sheet debt into account when assessing the valuation‐relevance of such gains. For those who advocate the control and components approach to securitization accounting, our results suggest that, at least for frequent securitizers, the put option arising from implicit recourse is a “missing piece” that is not currently accounted for when calculating securitization gains. Our results challenge the extant measurement standards in SFAS No. 140. 相似文献

This paper examines the cumulative market reaction to the events related to deferral of internal control audit requirement under the Sarbanes-Oxley Act of 2002 and its elimination under the Dodd-Frank Act of 2010 for nonaccelerated filers (small firms). We document that small firms experienced negative cumulative abnormal returns around these events; and the differences between the cumulative abnormal returns for small firms and the two control groups (accelerated and large accelerated filers) were negative and significant at the 1% level. These results support the notion that market participants value the reliability of financial information irrespective of the firm size. Within the small firms, we find no firm characteristic significantly explains the market reaction to the events considered. That is, all small firms lost market value in reaction to the events that delayed and eliminated their internal control audit requirement. 相似文献

We show how credible revelation and ability to commit to quality choice effect equilibrium qualities and welfare when product
market is either Bertrand or Cournot competition. We show that results depend on the type of competition but not generally
on the cost of quality function. We show that with Bertrand competition, the equilibrium qualities are lower with credible
commitment. Competition is moderated and producer surplus is higher and consumer surplus lower. With Cournot competition,
higher quality will be better but lower quality will be worse with credible commitment. Consumer surplus is always greater
with credible commitment and if cost does not increase too quickly with quality, producer surplus will also increase. Thus
credible commitment is a collusive device with Bertrand competition but it can improve social welfare with Cournot competition.

To evaluate the quality of reporting in published randomized controlled trials (RTCs) in the field of fall injuries. The 188 RTCs published between 2001 and 2011, indexed in EMBASE and Medline databases were extracted through searching by appropriate keywords and EMTree classification terms. The evaluation trustworthiness was assured through parallel evaluations of two experts in epidemiology and biostatistics. About 40%–75% of papers had problems in reporting random allocation method, allocation concealment, random allocation implementation, blinding and similarity among groups, intention to treat and balancing benefits and harms. Moreover, at least 10% of papers inappropriately/not reported the design, protocol violations, sample size justification, subgroup/adjusted analyses, presenting flow diagram, drop outs, recruitment time, baseline data, suitable effect size on outcome, ancillary analyses, limitations and generalizability. Considering the shortcomings found and due to the importance of the RCTs for fall injury prevention programmes, their reporting quality should be improved. 相似文献

The Center for Medicare and Medicaid Services (CMS) created the Hospital Compare Program in 2003 to increase transparency between healthcare providers and consumers. Implemented in 2005, this transparency consists of hospitals' collecting and making publicly available a set of hospital quality score measures. The CMS induced participation by financially penalizing hospitals that did not publicly report a specific subset of these measures (called “starter” measures). Three years into the program, the penalty for non-reporting both the starter measures and other (“non-starter”) measures was increased. I use a difference-in-differences methodology to analyze the effect of the increased CMS penalty on the likelihood that a hospital publicly reported its starter and non-starter measure scores. I find that the penalty had an economically and statistically insignificant effect on the probability that a hospital publicly reported its starter scores, but a statistically significant 8.0 percent effect (p-value<0.01) on whether it reported its non-starter scores. These findings are robust to a series of alternative empirical specifications. 相似文献

The medical tourism literature lacks insight into related issues of these types of partnerships. Those that integrate multiple perspectives into one research framework are especially rare. This study evaluated and compared the influence of external environment uncertainty, trust, and resource dependence perspectives on the quality of interorganizational partnerships in the international medical tourism market and quantified these elements using external environment uncertainty assessment on the international medical tourism development. The research sample was based on a survey from 161 travel agency managers in Taiwan. This study found that external environment uncertainty has direct negative impact on trust and resource dependence has a positive influence on interorganizational partnership. Moreover, trust has a significant impact on partnership quality while resource dependence does not. Therefore, medical travel agents should extend their network of trustworthy health care organization partners in order to improve performance, decrease their self-risk, collect information, and avoid missed opportunities. 相似文献

提出了一种基于灰色关联分析来研究质量屋中顾客需求与工程特性相关关系的方法。运用广义灰色关联分析中的绝对灰色关联分析进一步讨论,通过专家、顾客、厂商综合的打分方法来获得初始的顾客需求以及工程特性的重要度矩阵,然后通过相关的计算来得到绝对灰色关联度,最终得到需求-特性绝对灰色关联矩阵。再通过得到的矩阵进行优势分析,从而确定工程特性重要度的排序以及"瓶颈技术"。最后通过一个具体的实例来说明该方法的运用。 相似文献

本文从需求和供给两方面分析了独立审计市场中的审计质量均衡状况及其成因,研究发现:一方面,由我国公司治理不完善而引发的对独立审计的代理需求不足,以及特定融资制度下对低质量审计的融资需求强劲,使得我国独立审计的自愿性需求严重匮乏,从而审计师缺乏提高审计质量的内在经济动机;另一方面,现有法规对审计师的激励不足、约束不够,因此目前审计师提供的审计服务质量难于达到社会公众的期望-《独立审计准则》的要求.最后,笔者针对出现的问题提出相应的政策建议. 相似文献

地方政府“以地谋发展”的策略在促进各地区制造业大规模集聚和出口贸易快速增长的同时,也势必会给企业出口产品质量带来深刻影响。本文综合利用中国土地市场网城市土地交易数据、中国工业企业数据、中国海关进出口产品数据和中国城市面板数据,实证检验了土地市场扭曲对企业出口产品质量升级的影响,并对其内在机制进行了探讨。研究发现:中国城市建设用地配置存在明显的工业偏向性,进而导致工业用地价格被低估,产生工业用地应得收益大于实际价格的反向扭曲问题。这种反向扭曲可通过抑制技术进步、阻碍产业结构高级化、弱化集聚经济效应等机制显著降低制造业企业出口产品质量。土地市场扭曲对企业出口产品质量升级的影响具有明显的异质性特征。具体而言,土地市场扭曲不利于一般贸易企业与混合贸易企业出口产品质量提升,但对加工贸易企业出口产品质量提升具有促进作用。土地市场扭曲对企业出口产品质量升级的抑制作用由东到西依次递增。土地市场扭曲不利于外资企业和国有企业出口产品质量提升,对集体企业及民营企业的影响不显著。 相似文献

邮政系统服务质量模糊综合评价研究 总被引:1,自引:0,他引:1
邮政系统服务质量取决于各项邮政业务,邮政业务的服务质量取决于顾客的评价。以陕西省为例,利用陕西省邮政服务状况的调查数据对邮政系统服务质量进行了模糊综合评价。模糊综合评价的结果有赖于调查数据的代表性、评价指标体系的完善程度和评价指标的权重。 相似文献
