Dispersed Trading and the Prevention of Market Failure: the Case of the Copenhagen Stock Exchange

With augmented demands on power grids resulting in longer and larger blackouts combined with heightened concerns of terrorist attacks, trading institutions and policy makers have widened their search for systems that avoid market failure during these disturbing events. We provide insight into this issue by examining trading behaviour at the Copenhagen Stock Exchange during a major blackout. We find that although market quality declined, markets remained functional and some price discovery occurred during the blackout period suggesting that the NOREX structure of interlinked trading systems combined with widely dispersed trading locations may be a viable means of protection against market failure during massive power disruptions or terrorist attacks.     

中国核电产业国产化发展分析

自第一座军用堆的建成到2019年7月三代核电机组再次获批建设,我国核电经历了长期的发展,进入了核电重启时期。主要简述了不同发展阶段的核电技术路线,核电设备国产化率,以及相关的发展规划。我国核电产业的发展,是核电产业和制造业的奋斗史。核电设备的国产化率在有限的核电项目中不断提高。面对核电国产化过程中遇到的技术难点,我国核电从设计院到制造商共同承担风险,突破困境,实现了三代技术的国产化。在更先进的核电技术需求背景下,核电产业需要建立可持续发展的先进产业设备制造供应管体系。     

论税收立法权纵向划分的基本思路

目前我国税收立法权纵向划分存在着缺乏稳定的规则、行政性特征明显、税收立法权过度集中于中央、地方隐性税收立法严重等突出问题.我国税收立法权纵向划分改革的基本思路是:在宪政的基础上通过法律的方式建立适合我国国情的分税制公共财政体制;在此框架下结合分税制其他配套制度的完善将税收立法权总体上集中于中央;赋予地方必要的税收立法权,并对其进行制约与监督.     

Three‐period,two‐treatment crossover design under long‐term carryover effect

The paper describes non‐parametric approach for analysis of a three‐period, two‐treatment, four‐sequence crossover design in which test procedure for interchangeability of the treatment effects is obtained. The proposed procedure is based on a non‐parametric model, which incorporates, along with the direct treatment effects and the usual carryover effects, the long‐term carryover effects. Relevant competitors are obtained. Related asymptotic results are given. By performing simulation study, we compared the procedures with respect to type I error rate and power. Furthermore, confidence intervals for treatment differences are studied. The procedures are illustrated with a data study.     

分布式数据库技术在铁路局供电管理中的应用

郑州铁路局在电气化铁道的供电系统中应用“铁路牵引供电管理信息系统”(EMIS)实现了联网管理、信息共享。对于这种异地数据的应用处理面临着数据同步、数据共享、并行处理、数据传输等4个主要问题,为此EMIS采用了适合于现有网络条件的分布式数据库技术。在分析分布式数据库面临的安全问题的基础上,介绍了EMIS采用的安全保密措施,并针对其不足提出了有关建议措施。     

Measuring the persistence of deviations from purchasing power parity with a fractionally integrated STAR model

Empirically, elements of both fractional long memory and threshold non-linearity are present in the real exchange rates of the G-7 countries against the US, notably in the EU countries. Estimated half lives of deviations from PPP using median unbiased corrections to conventional linear autoregressive models corroborate existing evidence related to the PPP paradox as half lives range from at least four years to an infinite number of years. In contrast, for each EU country, accounting for threshold non-linearity results in estimated half lives that can be less than three years even with the allowance for fractional long memory.

Public Disclosure of Audit Fees and Bargaining Power between the Client and Auditor: Evidence from China

Before the public disclosure of audit fees was mandated, it was unlikely for an audit client to have accurate information about how much other companies were charged by their auditors. Public fee disclosure decreases the cost of auditees' access to audit fee information for the auditor's portfolio of clients and is thus likely to increase the relative bargaining power of auditees over auditors when they negotiate audit fees. Using both proprietary and public audit fee data before and after public fee disclosure was mandated in China, we provide evidence consistent with the preceding conjecture. We find that public fee disclosure reinforces the magnitude of audit fee decreases for overcharged clients and weakens auditors' ability to raise audit fees for undercharged clients. These findings suggest the existence of unintended consequences of public fee disclosure regulation, the original rationale of which was a concern about audit pricing practices that could undermine auditor independence.     

财务重述、管理层权力与股价崩盘风险：来自中国证券市场的经验证据

股市震荡引发投资者和监管层对股价崩盘风险的关注。从财务重述背后所反映的财务信息质量低下和公司治理失效出发,探讨其对股价崩盘风险的影响,结合管理层权力这一影响组织行为和产出能力的代理人特征,探讨其对财务重述与股价崩盘风险之间关系的影响。研究结果表明：相比未发生财务重述的公司,发生了财务重述的公司的股价崩盘风险明显更高;进一步纳入代理人特征———管理层权力后,发现代理人的这一特征对上述关系有明显的促进作用。
