经过了十多年的发展,重大疾病保险现已成为人身保险市场上重要的保障型产品。随着经营主体的不断增多,保险人和投保人对于重大疾病的定义认识存在差异,客观上,也容易产生理赔纠纷。在理赔投诉中,涉及重大疾病险种的投诉所占的比重越来越高,并继续呈逐年上升趋势。 相似文献

四季轮回,时光飞逝。灾难和挑战并存、精彩和机遇同在的2008年离我们渐渐远去,留下的是一张张意味深长的画卷,一幅幅精彩无限的瞬间,一个个回昧无穷的时刻。 相似文献

This data insight highlights the Transportation Security Administration (TSA) claims data as an underused data set that would be particularly useful to researchers developing statistical models to analyze claim frequency and severity. Individuals who have been injured or had items damaged, lost or stolen may make a claim for losses to the TSA. The federal government reports information on every claim from 2002 to 2017 at https://www.dhs.gov/tsa-claims-data . Information collected includes claim date and type and site as well as closed claim amount and disposition (whether it was approved in full, denied, or settled. We provide summary statistics on the frequency and the severity of the data for the years 2003 to 2015. The data set has several unique features including severity is not truncated (there is no deductible), there are significant mass points in the severity data, and the frequency data shows a high degree of auto correlation if compiled on a weekly basis, and substantial frequency mass points at zero for daily data. 相似文献

In this paper we present two different approaches to how one can include diagonal effects in non-life claims reserving based on run-off triangles. Empirical analyses suggest that the approaches in Zehnwirth (2003) and Kuang et al. (2008a, 2008b) do not work well with low-dimensional run-off triangles because estimation uncertainty is too large. To overcome this problem we consider similar models with a smaller number of parameters. These are closely related to the framework considered in Verbeek (1972) and Taylor (1977, 2000); the separation method. We explain that these models can be interpreted as extensions of the multiplicative Poisson models introduced by Hachemeister & Stanard (1975) and Mack (1991). 相似文献

案情介绍 某中间商陈某以A国M公司名义与国内W外贸公司签订了一份向M公司出口40余万美元圣诞灯的售货合同,支付方式为D/A60天.W公司就此向中国信保申请信用限额,经资信调查和评估,中国信保批复了40万美元的信用限额,支付方式为D/A 60天.同年8月,W外贸公司以被保险人身份,就该合同项下出口向中国信保申报,并足额交纳了保费.尔后,W公司按约向A国M公司发货,但到了应付款日,M公司一直没有还款.W公司向中国信保填报可损. 相似文献

Paralleling regulatory developments, we devise value-at-risk and expected shortfall type risk measures for the potential losses arising from using misspecified models when pricing and hedging contingent claims. Essentially, P&L from model risk corresponds to P&L realized on a perfectly hedged position. Model uncertainty is expressed by a set of pricing models, each of which represents alternative asset price dynamics to the model used for pricing. P&L from model risk is determined relative to each of these models. Using market data, a unified loss distribution is attained by weighing models according to a likelihood criterion involving both calibration quality and model parsimony. Examples demonstrate the magnitude of model risk and corresponding capital buffers necessary to sufficiently protect trading book positions against unexpected losses from model risk. A further application of the model risk framework demonstrates the calculation of gap risk of a barrier option when employing a semi-static hedging strategy. 相似文献
