In the valuation of the Solvency II capital requirement, the correct appraisal of risk dependencies acquires particular relevance. These dependencies refer to the recognition of risk diversification in the aggregation process and there are different levels of aggregation and hence different types of diversification. For instance, for a non-life company at the first level the risk components of each single line of business (e.g. premium, reserve, and CAT risks) need to be combined in the overall portfolio, the second level regards the aggregation of different kind of risks as, for example, market and underwriting risk, and finally various solo legal entities could be joined together in a group.

Solvency II allows companies to capture these diversification effects in capital requirement assessment, but the identification of a proper methodology can represent a delicate issue. Indeed, while internal models by simulation approaches permit usually to obtain the portfolio multivariate distribution only in the independence case, generally the use of copula functions can consent to have the multivariate distribution under dependence assumptions too.

However, the choice of the copula and the parameter estimation could be very problematic when only few data are available. So it could be useful to find a closed formula based on Internal Models independence results with the aim to obtain the capital requirement under dependence assumption.

A simple technique, to measure the diversification effect in capital requirement assessment, is the formula, proposed by Solvency II quantitative impact studies, focused on the aggregation of capital charges, the latter equal to percentile minus average of total claims amount distribution of single line of business (LoB), using a linear correlation matrix.

On the other hand, this formula produces the correct result only for a restricted class of distributions, while it may underestimate the diversification effect.

In this paper we present an alternative method, based on the idea to adjust that formula with proper calibration factors (proposed by Sandström (2007)) and appropriately extended with the aim to consider very skewed distribution too.

In the last part considering different non-life multi-line insurers, we compare the capital requirements obtained, for only premium risk, applying the aggregation formula to the results derived by elliptical copulas and hierarchical Archimedean copulas.  相似文献

近年来,城镇无保障老年人的养老问题日益受到政府和社会的关注。全国已有部分省市对城镇无保障老年人提供了一定的养老补贴待遇,但是,不同省市采用补贴形式各不相同,补贴标准也有一定的差异。目前,北京市城镇无保障老人主要是通过福利养老金制度覆盖,对满足年龄条件的无保障老人,每人每月都可以领取230元财政补贴。那么,在政府财力有限的条件下,如何提高无保障老人收入水平?本文提出了建立无保障老人个人缴费与政府补贴相结合的新制度,并依据2007年北京市城镇无保障老人调查数据,构建北京市无保障老人养老保险收支模型,计算并预测了未来10年的养老保险收支情况,通过这一模式表明,政府财政补贴在适度提高的前提下,无保障老人养老待遇会有较大幅度增加,而且该模式运行的稳定性较强。  相似文献

世界经济金融体系正在发生深刻变革。以中国、日本、韩国、东盟十国为代表的东方经济体具有超越西方经济体经济总量的潜力。在此背景下,需要倡导更积极的国际合作,共同致力于消除贫困、保护环境、消除收入分配不平等、应对人口结构变化挑战及加强国际和平领域合作等。此外,推动世界经济的可持续发展具有重要意义,特别是在能源结构转型、粮食生态保护、教育质量、饮食健康、城市建设及数字经济等领域。未来,世界将向多极化政治经济格局、多货币体系发展,建立更为合理的世界秩序。中国的经济发展及人民币国际化进程将有利于新格局的建立。  相似文献

Critics have alleged that securitization accounting prior to 2010 was among the causes of the recent financial crisis. In response to this criticism, the Financial Accounting Standards Board (FASB) implemented two new accounting standards, SFAS 166 and SFAS 167, to improve the financial reporting for securitizations. Bank regulators have stated their belief that SFAS 166/167 will result in a consolidated balance sheet (and risk-based capital ratios based thereupon) that better reflects a bank's exposure to risk related to securitized assets. We document that, by ceding retained power or influence through the servicing/special servicing functions to third parties, SFAS 166/167 resulted in real effects to the extent that banks (particularly those that were weakly capitalized) achieved their accounting objectives in the post-SFAS 166/167 period through legitimate transaction structuring in line with the intent of the new rules. Further, we use capital market participants’ assessments of risk retention by sponsoring banks as a benchmark, and provide evidence consistent with bank regulators’ beliefs. In particular, following SFAS 166/167, equity investors of sponsoring banks do not consider (consider) as risk relevant securitized assets that receive off-balance sheet (on-balance sheet) treatment. Securitized assets that are consolidated under SFAS 166/167 exhibit the same risk relevance as assets that are not securitized, despite contractual provisions that would seem to imply substantial risk transfer.  相似文献

The recent establishment of the £20 million Teaching and Learning Technology Programme by the Universities' Funding Council in the UK provides one of the largest boosts for IT and education since PLATO (in the USA) and NDPCAL (in the UK). This note describes the BITE project which is part of the above programme and highlights some of the problems that have affected both the development and evaluation of accounting courseware in the past. By using a strong interdisciplinary team of software, educational and subject specialists, the project hopes to overcome some or all of these problems.  相似文献

This paper empirically tests the random walk and efficiency hypothesis for 12 Asia-Pacific foreign exchange markets. The hypothesis is tested using individual as well as panel unit root tests and two variance-ratio tests. The study covers the high (daily) and medium (weekly) frequency post-Asian crisis spot exchange rate data from January 1998 to July 2007. The inferential outcomes do not differ substantially between the unit root tests and the variance-ratio tests when using daily data but differ significantly when using weekly data. With the daily data, both types of unit root tests identify unit root components for all the series and two variance-ratio tests provide the evidence of martingale behavior for majority of the exchange rates tested. With the weekly data, panel unit root tests identify unit root component for the exchange rates and, the unit root tests on a single series basis identify unit root component for 10 foreign exchange markets. However, the variance-ratio tests reject the martingale null for the majority of the exchange rates when using weekly data.  相似文献

上市公司反收购中的章程应用及法律规制   总被引:1,自引:0,他引:1  
公司章程是公司的宪章性文件,是公司实现自治的重要手段。在上市公司收购中,目标公司通常通过公司章程的修订,在其中置入相应的反收购条款,以防止或者抵制敌意收购。由于我国的公司、证券法律法规对上市公司反收购问题规定的相对欠缺,导致实践中利用公司章程实施反收购出现失范的情况较为明显。本文尝试分析如何在现行法律框架内对利用公司章程实施反收购的行为进行有效规制,并提出相应的政策建议。  相似文献

Using 1640 observations of completed acquisitions from 1996 to 2003, we investigate the relation between corporate governance and returns to bidders and targets. We find that the cumulative abnormal returns for acquirers are significantly negative upon announcement of acquisitions for the full sample and for the related and diversifying subsamples. However, we find that diversifying acquisitions, when conducted by firms with a higher percentage of outsiders on the board, improve returns. Furthermore, we separately examine high‐technology and non‐high‐technology firms to test the relation between board characteristics and announcement returns in different information asymmetry environments. We also find that diversifying acquirers with independent boards perform better than those with insider‐dominated boards and the results are especially pronounced for high‐technology firms. Taken together, the results suggest that firms with better incentive alignment will be more likely to be perceived by the market as stronger performers in acquisitions. In sum, we find that corporate governance plays an important role in determining wealth creation for our sample of acquiring firms.  相似文献
