浅谈会计信息失真的原因及防范措施

会计信息的质量好坏影响经济工作决策的质量,对于企业本身、甚至于整个国民经济都有不可估量的作用。失真的会计信息对单位、社会、国家的危害非常严重。分析会计信息失真的主要原因,提出其防范措施便具有现实意义。     

Nyquist采样频率下的频谱失真与采样定理

本文通过在Nyquist采样率下对信号的频谱是否发生失真，发生了怎样的失真的讨论，分析了在进行离散傅立叶变换（DFT）时，采样定理在其边界条件下进行信号处理时存在的问题。展示了在该条件下频谱发生严重失真的形式和程度，最后从无失真地恢复时域信号x(t）的角度讨论了DFT意义下采样定理的表述。     

Multivariate Return Decomposition: Theory and Implications

In this paper, we propose a model based on multivariate decomposition of multiplicative – absolute values and signs – components of asset returns. In the m-variate case, the marginals for the m absolute values and the binary marginals for the m directions are linked through a 2m-dimensional copula. The approach is detailed in the case of a bivariate decomposition. We outline the construction of the likelihood function and the computation of different conditional measures. The finite-sample properties of the maximum likelihood estimator are assessed by simulation. An application to predicting bond returns illustrates the usefulness of the proposed method.     

基于委托代理理论的会计信息失真问题研究

会计信息失真问题越演越烈,并且已成为一个世界性难题。可靠性、真实性、相关性是会计信息质量的生命,但一系列会计舞弊行为的发生已篡改了会计信息的本来面目,会计信息"诚信工程"摇摇欲坠。造成会计信息失真的原因有很多,就此,我国也采取了相应的措施予以治理,但效果并不显著,往往是治标不治本。本文从产生会计信息失真问题的根源出发,重点剖析了在以委托代理理论为根基的现代股份制企业中会计信息失真的原因,并提出了提高委托代理制度下的会计信息质量的相应对策。     

On additive-multiplicative hazards model

In survival analysis and reliability theory, a fundamental problem is the study of lifetime properties of a live organism or system. In this regard, there have been considered and studied several models based on different concepts of ageing such as hazard rate and mean residual life. In this paper, we consider an additive-multiplicative hazard model (AMHM) and study some reliability and ageing properties of the proposed model. We then specify the bivariate models whose conditionals satisfy AMHM. Several properties of the proposed bivariate model are investigated and adequacy of the model is evaluated based on a real data set.     

从执行主体角度探寻政策执行失真的原因

政策在执行过程中存在着"有令不行、有禁不止","上有政策,下有对策"等严重妨碍政策目标有效实现的不良情形.公共选择理论认为,把作为微观经济分析出发点的个人作为集体行为的出发点,将个人的选择或决策当作公共选择或集体决策的基础.从个体的角度看,政策执行主体的素质缺陷、信息垄断和利益追求导致了政策执行失真.     

政府补贴对企业真实创新绩效的影响——基于中国A股上市公司数据的实证分析

在分析政府补贴政策的特征及其影响企业真实创新绩效的理论机制的基础上,运用A股上市公司数据,检验了政府补贴对企业真实创新绩效的直接和传导效应。研究发现：政府补贴对企业真实创新绩效具有激励效应,且国有企业较非国有企业的创新效应更强;研发资本要素市场扭曲能够强化政府补贴激励企业真实创新绩效的调节作用,并与产权性质联合调节政府创新补贴效果;创新投入与融资约束在政府补贴对企业真实创新绩效的影响中起部分中介效应;政府补贴对企业创新持续性具有负向抑制效应,政府补贴效果受到研发资本要素市场扭曲和产权性质明显的负向调节作用,且创新投入与融资约束在政府补贴对企业持续性创新的影响中起部分中介效应。     

On the estimation of a sensitive quantitative mean using blank cards

In this article, we introduce for the first time, the blank card methods for estimation of finite population mean of a sensitive variable. Two generic randomization devices are suggested, and for each device we identify the choices of special models. We introduce additive, multiplicative, and combination of both additive and multiplicative scrambling models that require use of a non sensitive variable. We derive the basic statistical properties of each model. It is interesting to note that various existing estimators can be viewed as the special cases of those presented here. The statistical efficiency of proposed techniques is compared with Greenberg et al. (1971 Greenberg, B.G., Kuebler Jr, R.R., Abernathy, J.R., Horvitz, D.G. (1971). Application of the randomized response technique in obtaining quantitative data. J. Am. Stat. Assoc. 66(334):243–250.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) and modified Perri (2008 Perri, P.F. (2008). Modified randomized devices for Simmons’ model. Model Assisted Stat. Appl. 3(3):233–239. [Google Scholar]) model. The proposed devices can easily be adjusted to achieve the required efficiency level by making suitable choices of different design parameters.
