操作风险高级计量法及其验证:国际经验与启示   总被引:4,自引:0,他引:4  
操作风险计量既是一个新题,也是一个难题。本文系统总结了操作风险高级计量法中的内部计量法和损失分布法,比较了部分国际金融机构在这方面的实践做法。在此基础上,指出了高级计量法应用时所需验证的内容及其相应的验证方法。最后,总结了我国银行业应用高级计量法时应注意的主要问题并给出了可供解决问题的思路。  相似文献

强势美元政策:有效性检讨与可持续性分析   总被引:2,自引:0,他引:2  
强势美元政策保证了外资对美国的强劲流入,支撑了美国的低通货膨胀,弥补了美国的储蓄———投资缺口和对外贸易逆差,巩固了美元的全球霸权地位,总之,强势美元政策促进了美国的经济增长。由于美国存在对强势美元政策的依赖性及美元的全球霸权地位没有受到实质性的挑战,在可预见的将来,强势美元政策仍会持续也仍可持续,美国仍将实行强势美元政策。  相似文献

内部评级体系定量验证模型及在中国银行业的应用   总被引:1,自引:0,他引:1  
定量验证是运用一定的统计方法来检验商业银行已运行内部客户评级体系的准确性、审慎性及稳定性。准确性验证主要检验商业银行的内部评级模型对授信客户信用状况好坏的风险识别能力;审慎性验证主要检验银行所采用的政策与标准在辨别其内部评级和风险参数量化上的保守程度;稳定性验证则主要检验在风险不变的情况下,银行所采用政策和标准能够保持评级与估值总体上不发生变化。本文介绍了常用的定量验证模型及流程,并以中国某商业银行进行定量验证的实践为例,介绍了如何进行银行内部评级体系的定量验证及在具体实践中可能遇到的问题及解决方案。  相似文献

In management accounting the experimental method has been under-utilised compared to other disciplines such as auditing. This paper examines considerations necessary in experimental design to ensure both internal validity and experimental realism with the aim to increase utilisation of this methodology in management accounting. Task design, experimental design, experimental procedures and post-test questionnaire design are addressed specifically as they form the basic building blocks of most experiments. This paper also examines 'lessons' learned both in the design and administration of the experiment to help researchers in the use of the experimental method. Potential changes to the experiment are discussed, as part of an opportunity to improve future research work using the existing or a similar experiment  相似文献

证券市场风险的最大特点是强烈的外部性,这种外部性主要是由系统性风险决定的。风险的外部性要求加强证券监管,但风险监管中存在的俘虏、寻租、时滞等原因,降低了证券市场的效率。文章分析了证券市场风险监管的目标、取向和模式等,认为应充分发挥自律组织在风险防范中的一线缓冲作用,避免证监会承受过大的社会压力,逐步向“以自律为基础,政府监管为主”的监管体系过渡。  相似文献

Hedonic regression has become the standard approach for modeling the behavior of house prices. Usually, the common price component is modeled via dummy variables. Based on an approximation for the present value, we deliver an economic interpretation of the common price component. This allows to include explanatory factors like inflation rates, mortgage rates and building permissions. The notional rents for houses are fitted with a flexible hedonic function. We use the EM algorithm to estimate our model with monthly data of single-family house sales from the four South-West districts of Berlin, Germany from 1982:8 to 1999:12. Emphasis is put on the interpretation of the results.  相似文献

Hedonic models are commonly used to estimate marginal willingness to pay for environmental amenities. These studies utilize variables that are assumed to be measured without error (such as the square footage of the lot or the number of bedrooms) and proxy variables (such as neighborhood or school quality). Lot and structural characteristics may in fact be measured with error. Potential sources of error include inaccurate measures and inconsistent updating. We investigate the effect of using tax-assessor data versus survey data from purchasers to estimate the implicit price of an environmental amenity, lake-water clarity. Convergent validity of the implicit price for water clarity is established if the town and survey data provide statistically indistinguishable estimates of implicit prices for this amenity. Overall, the town-office and survey data on property characteristics were not statistically different in three of the four market groupings examined, which suggests that the traditional municipal sources of these data may not contain substantial measurement error. Furthermore, convergent validity is satisfied in all four market areas. However, differences in computed implicit prices of clarity in two of the market areas are large enough that policy decisions for environmental quality could be affected by the source of the lot and structural data.  相似文献

This paper proposes a new nonparametric approach to the problem of inferring term structure estimates using coupon bond prices. The nonparametric estimator is defined on the basis of a penalized least squares criterion. The solution is a natural cubic spline, and the paper presents an iterative procedure for solving the non-linear first-order conditions. Besides smoothness, there are no a priori restrictions on the yield curve, and the position of the knots and the optimal smoothness can be determined from data. For these reasons the smoothing procedure is said to be completely data driven. The paper also demonstrates that smoothing a simple transformation of the yield curve greatly improves the stability of longer-term yield curve estimates.  相似文献

为防范涉农贷款违约风险,部分农村信用联社积极探索,创新出债权文书公证方式、以人身险保险金担保债权等担保方式,以确保债权得到切实维护.这些新担保方式一定程度上增加了农村贷款供给,但存在法律风险.本文着重对这些新措施、新方法的合法性及有效性进行了探讨.  相似文献
