武汉金融安全区模式设计与研究

金融安全与稳定直接关系到一个国家或地区的经济安全与社会稳定。一个地区 ,在突出的支付风险得以逐一化解之后 ,适时启动创建金融安全区工程 ,并以此全面提高金融监管水平 ,实现区域金融业持续稳健发展已经成为当前我们面临的重要课题。本文在论证武汉市开展创建金融安全区的必要性和可行性的基础上 ,提出了构建以武汉金安指数为核心的指标监测体系、具体创建规划以及相应运行规程。

The impact on stock prices of deferral and elimination of internal control audit requirement for small firms

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.     

Effect of credible quality investment with Bertrand and Cournot competition

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. Received: February 8, 2000; revised version: February 14, 2002 RID="*" ID="*" The idea of this paper originated in the weekly workshops of Mordecai Kurz at Stanford. I am forever in debted to Mordecai and fellow students – Luis Cabral, Peter DeMarzo, John Hillas, Michihiro Kandori, Steve Langois, Patrick McAllister, Steve Sharpe, Peter Streufert, Steve Turnbull and Gyu-Ho Wang – for their criticism and encouragement. I also benefited from comments from Yi-Heng Chen, Jin-Li Hu, Kala Krishna, Jinji Naoto, Thomas J. Prusa, and Shyh-Fang Ueng at various later stages of this work. Last but not least, I am grateful for the detailed comments of the referee.     

A critical appraisal of the reporting quality of published randomized controlled trials in the fall injuries

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.     

The Challenge of Humanistic Economics

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.     

论国际金融危机对完善我国金融监管法制的警示

法律时宏观调控与微观规范层面多方面的错误共同作用所产生的结果,是最终引发国际金融危机的深层次原因之一.美国法律对美联储宽松货币政策规范不力是酿成危机的重要根源,金融信贷管制法律松弛助长"次贷"违规通行无阻是酿成危机的重要隐患.金融监管体系存在法律漏洞是酿成危机的重要因素,法律长期缺乏对金融技术与制度创新保持协调发展的规范是酿成危机的关键性因素.国际金融危机警示我们,必须依法推进市场调节与政府调控实现相辅相成,强化金融监管措施,强化对金融创新风险的防控,力求法律监管机制防范金融风险的全覆盖,依法防控国际金融危机对实体经济影响的深入.     

当代大学教育改革中的两难问题

高等教育的宗旨在于培养全面发展的人,但目前扭曲的教育质量评价机制使大学教育改革面临诸多两难抉择,事实上的结果是背离了这一宗旨。当前,大多数高校所面临的主要两难问题包括培养完人还是工具人、科研为重还是教学为重、收益导向还是质量导向等三方面。这些问题之所成为两难问题主要是因为评价导向不合理,所以化解这些两难问题的主要途径就是开发合理的评价机制,营造公正的学术环境。     

农村教育发展的财政保障

长期以来农村教育的特征,说明教育经费短缺一直是农村教育发展的突出矛盾。要对农村教育实施财政保障,须以整顿农村教师队伍为前提,在教育观念、国民经济结构、教育结构、政府预算结构及财政体制等五个方面作战略性调整,同时制止对学生的乱收费。     

《高等应用数学》定积分的教学探索

数学教学改革多年都流于形式,传统性强,权威性高,是问题所在。本人将传统16课时定积分教学,打破传统模式,改造成6课时教学,收到了很好的效果,现在拿出来与读者共享。
