Sequential control of time series by functionals of kernal-weighted empirical processes under local alternatives

Motivated in part by applications in model selection in statistical genetics and sequential monitoring of financial data, we study an empirical process framework for a class of stopping rules which rely on kernel-weighted averages of past data. We are interested in the asymptotic distribution for time series data and an analysis of the joint influence of the smoothing policy and the alternative defining the deviation from the null model (in-control state). We employ a certain type of local alternative which provides meaningful insights. Our results hold true for short memory processes which satisfy a weak mixing condition. By relying on an empirical process framework we obtain both asymptotic laws for the classical fixed sample design and the sequential monitoring design. As a by-product we establish the asymptotic distribution of the Nadaraya-Watson kernel smoother when the regressors do not get dense as the sample size increases.Acknowledgements The author is grateful to two anonymous referees for their constructive comments, which improved the paper.

《消法》中"加倍赔偿"法律责任的理解和适用

对《消法》第49条的加倍赔偿法律责任的正确理解有两个前提加倍赔偿法律责任的性质和加倍赔偿法律责任的立法精神.适用加倍赔偿法律责任的关键问题是如何认定欺诈,欺诈的四个构成要件是认定的依据.加倍赔偿法律责任在适用中应注意第三人能否成为加倍赔偿法律责任适用的对象和加倍赔偿计算方法有不妥之处这两个问题,应对生产者、经营者共谋欺诈行为进行惩罚,并对赔偿标准进行修正.     

年度预算与中期预算:比较及借鉴

传统上,政府预算是以年度为基础进行编制的。目前,许多OECD国家则已转向中期预算,以弥补年度预算的缺陷。本文对年度预算和中期预算进行了比较,并指出了中期预算对我国预算改革的借鉴意义。     

Deane–Draper stores: employee empowerment in a retail environment

This case focuses on the application of employee empowerment principles to a large retail group. It provides the opportunity to analyse the manner of the strategy implementation and the consequent impact on both individuals and the organization. The case establishes significant financial underperformance in one part of a retail group and investigates the use of ‘employee empowerment’ techniques - following Carlzon (1987) - to provide a solution. The case illustrates the dysfunctional activity associated with implementing empowerment without either appropriate management control or staff training, together with the dire financial implications. The Teaching Resource Note discusses alternative approaches that might have been adopted.     

Application of LADM for the integration of land and housing information in China: The legal dimension

The integration of land and housing registration is a key opportunity for China: improved land governance is the intended outcome. Prior to the design of any integrated information system, the legal requirements the system must satisfy need to be identified. This paper identifies and reviews the legal requirements for the integration of land and housing information in China. Specifically, the existing legislative framework relating to land, consisting of seven levels of legislation, is interrogated. A collection of legal requirements emerges: these are categorized into themes including registration, maintenance, mortgage, transfer of real estate rights, relevant materials and archives, and preliminary notice. In order to be more applicable for the next design of the Land Administration Domain Model (LADM) country profile for China, these legal requirement are further converted into packages, classes and attributes by referring to the ISO 19152 standard. The existing databases of the Chongqing Municipality are used to support the modelling process. The paper concludes that the legal requirements can be used as a foundation for an integrated system in China.     

Bankruptcy and firm finance

This paper analyzes how an enforcement mechanism that resembles a court affects firm finance. The court is described by two parameters that correspond to enforcement costs and the amount of creditor/debtor protection. We provide a theoretical and quantitative characterization of the effect of these enforcement parameters on the contract loan rate, the default probability and welfare. We analyze agents’ incentive to default and pursue bankruptcy and show that when the constraints that govern these decisions bind, the enforcement parameters can have a sharply non-linear effect on finance. We also compute the welfare losses of “poor institutions” and show that they are non-trivial. The results provide guidance on when models which abstract from enforcement provide good approximations and when they do not.      

民间融资的法律分析

在我国民间融资已有近千年历史,进入建立社会主义市场经济后,民间融资的作用和功能更是得到了创新性的发挥。随着市场经济的发展,民间融资作为一种有效的资金资源配置手段,在优化资源配置、优化社会融资结构、弥补市场资金需求和促进民营经济发展中发挥着显著功效。但由于我国现有法律法规对民间融资的保护、规范和引导等问题上都存在诸多缺陷,严重制约着民间融资的发展,对市场经济的发展也产生了不利的影响。本文从法理的角度论证其合法性,分析我国民间融资的法律制度的弊端。并在此基础上提出了规范和完善民间融资法律制度的建议。     

Eighteenth-Century Evolutionary Thought and its Relevance in the Age of Legislation

This essay revisits the evolutionist writingsof the eighteenth century to clarify their key ideas concerninglegal and social evolution and to assess their relevance in thepresent era of pervasive legislation. The discovery of the principleof the accumulation of design is traced to these writings andthe continuity of twentieth century spontaneous-order theoryand new institutional economics with this tradition is noted.While highlighting the contributions of other institutional theoriststo the elucidation of the role of purposive action in legal evolution,the author argues that input designing does not alter the fundamentalnature of legal emergence as postulated by the eighteenth centuryscholars. The essay supports the ideal of legal generality, freespeech, property and contractual freedom as normative implicationsof the evolutionary viewpoint.     

Do the English Legal Origin Countries have More Dispersed Share Ownership and More Developed Financial Systems?

The essence of the legal origin hypothesis is that a country with an English legal origin provides better investor and creditor protection and experiences greater financial development; financial institutions and stock markets flourish, the general public participate more in financing investment projects of companies and so shareholding is less concentrated. The present paper examines this hypothesis on the basis of a cross‐country study of 85 countries. We find no evidence of more dispersed share ownership in the English law countries than in other countries with different legal origins irrespective of whether we adjust for the existence of transitional economies and less developed countries in the sample. Using three indicators of development of banking and other credit institutions and four indicators of stock market developments, we also find no evidence of more developed financial systems in the English law countries. As expected, there is some evidence of lower financial development in the less developed countries and transitional countries. It is not the English law heritage but the security of persons and goods that appears to explain the cross‐country variations in financial development.     

关联交易与控制性股东的"隧道行为"

在信息不对称情况下,控制性股东能够利用其对上市公司的控制力或影响力进行非公允关联交易,从而以其他投资者的利益为代价从上市公司攫取财富.本文以1998-2005年实施配股的上市公司为样本,分析了配股后上市公司关联交易的分布特征,并研究了关联交易对控制性股东资金占用行为、股票收益和企业价值的影响.研究结果表明:(1)控制性股东通过关联借贷大量侵占了上市公司的资金;(2)投资者在关联交易发生后相应调整了股票价格,导致了上市公司股票收益下降;(3)控制性股东通过隐蔽的关联交易从上市公司输出了财富,造成了以托宾Q衡量的公司价值下降,关联交易与公司价值之间存在负相关关系.非公允关联交易成为控制性股东掠夺中小股东财富的重要方式,导致上市公司的资源被不断输送出去.
