经济利润及折现现金流在企业价值评估中的应用研究 总被引:3,自引:0,他引:3
几个世纪以来,经济学家一直在试图说明,只有经济利润才能够真正反映企业的价值创造能力,而会计利润则或多或少地扭曲了企业所创造的价值,因此必须进行会计调整才能使会计利润与经济利润一致。经济利润在企业价值评估中起着非常重要的作用,本文从折现现金流的方法入手,推导出企业价值和经济利润之间所存在的必然联系。 相似文献

基于因子分析法以及商业银行年度报告中常用的经营指标作为风险因子来建立因子分析方程,并对商业银行风险进行评价,以及将评价结果与商业银行管理费用率进行回归后发现,两者之间存在明显的相关关系,商业银行风险评价得分越高,其风险水平就越低,其当年的管理费用率就越低,即商业银行风险管理水平对其当年的经营成本有直接影响。 相似文献

Robustness issues in multilevel regression analysis 总被引:8,自引:0,他引:8
A multilevel problem concerns a population with a hierarchical structure. A sample from such a population can be described as a multistage sample. First, a sample of higher level units is drawn (e.g. schools or organizations), and next a sample of the sub‐units from the available units (e.g. pupils in schools or employees in organizations). In such samples, the individual observations are in general not completely independent. Multilevel analysis software accounts for this dependence and in recent years these programs have been widely accepted. Two problems that occur in the practice of multilevel modeling will be discussed. The first problem is the choice of the sample sizes at the different levels. What are sufficient sample sizes for accurate estimation? The second problem is the normality assumption of the level‐2 error distribution. When one wants to conduct tests of significance, the errors need to be normally distributed. What happens when this is not the case? In this paper, simulation studies are used to answer both questions. With respect to the first question, the results show that a small sample size at level two (meaning a sample of 50 or less) leads to biased estimates of the second‐level standard errors. The answer to the second question is that only the standard errors for the random effects at the second level are highly inaccurate if the distributional assumptions concerning the level‐2 errors are not fulfilled. Robust standard errors turn out to be more reliable than the asymptotic standard errors based on maximum likelihood. 相似文献

Revisions to the European Treaty of Union require some form of environmental appraisal – primarily risk assessment and cost-benefit
analysis – of regulatory initiatives by the European Commission. A retrospective look at the emergence of environmental appraisal
also shows that, while the Commission has made great advances in introducing cost-benefit or cost-effectiveness appraisals
in recent years, past environmental decisions and overall environmental policy have not been informed by systematic appraisal
techniques. Nor is it clear what role is now being played by risk assessments. While it is impossible to gauge the extent
to which systematic appraisal procedures will save on regulatory and compliance expenditures, some indications are provided
of the costs of past neglect of these procedures. 相似文献

The 2011 Global Economic Crime Survey instituted by PricewaterhouseCoopers (PwC) confirms the economic crime in Malaysia to be on the increase and, therefore, requires immediate attention to stem the tides. In anticipation of the challenges occasioned due to a shift from the modified cash basis to the accrual basis of accounting, the Malaysian State's determination to move from a developing nation to a developed nation, and to be ranked among the first 10 in 2020, this paper presents the need for forensic accountant and auditor capability (i.e., mindset and skills) on forensic accountant and auditor competence (i.e., task performance fraud risk assessment (TPFRA)) in the Malaysian public sector. It also draws the attention of the users of public sector accountants and auditors to the understanding of fraud mechanisms and how to deal with fraudsters. The population of this study comprised the accountants and auditors in the office of the Accountant General and Auditor General of Malaysia. The objective of this paper is to investigate the competence requirements of accountants and auditors in the effective and efficient utilization of capability requirements, which have the potentials to usher in the best global practices in fighting fraud in the Malaysian public sector. 相似文献
