投资职能对保险公司风险的影响研究北大核心CSSCISSCI

基于手动收集的2009-2014年中国50家产险公司和57家寿险公司的面板数据,本文区分产险公司和寿险公司,从多个维度考察了保险公司的投资职能对风险的影响。研究发现,产险公司开展投资业务提高了偿付能力水平,对破产概率和流动性没有造成冲击;寿险公司开展投资业务提高了破产概率并加剧了退保行为。本文研究提供了降低保险业风险的政策启示:对于产险公司,可以适度鼓励发展投资业务,提高收益进而降低风险;对于寿险公司,则需要抑制激进投资和投资型产品发展过热的倾向。     

流“金”岁月（下）让“保险”回归“保险”

寿险公司通过保险和投资业务创造价值。其主要利润来源有三个：承保业务、投资业务和管理费收入。寿险公司过往主要专注于防范死亡风险,如今则提供全方位寿险（如死亡险、疾病险和长寿险）和金融市场保险。盈利影响因素因产品类型而差异显著。对于以寿险为主的产品来说,盈利取决于承保表现和投资收益,后者对于长期产品的盈利尤其重要。对于有保...     

论中国寿险业利率风险的管理

一、利率风险是寿险公司经营面对的重要风险 (一)固定预定利率的寿险产品经营中存在利率风险 我国寿险业自1994年开始飞速发展以来,至1999年在市场上推出新型寿险品种如分红保险、投资连结保险和万能寿险为止,寿险公司经营的寿险产品都     

寿险业务结构失衡风险及化解建议

产品结构失衡,偏离保障功能 我国寿险公司普遍采取以盲目追求保费规模和市场份额为中心的非理性经营模式,存在着保障功能不足、业务结构不尽合理的问题。由于大力发展保费高的投资型产品和趸缴型产品,过度宣传寿险产品的投资功能,用短期投资回报来吸引客户购买,使产品结构呈现出短期业务多、趸缴业务占比大、保障型业务和长期业务占比不高的特点。2008年,我国寿险公司主营业务的70％以上都是新型寿险（新型寿险包括分红保险、万能寿险和投资连接保险等）,意外险和健康险这两类主要的风险保障型业务仅占总保费的15．32％。即便在发达国家,传统保障型产品的份额在新型产品的挤占之下也保持在40％以上。新型寿险过于注重投资,保障功能弱化,使寿险公司的整体结构出现规模快速膨胀、结构配比不良的隐患。     

基于倒向随机微分方程的非寿险定价实证研究——以广东财产险为例

考虑赔付约束的我国寿险业效率及全要素生产率研究——基于SBM方向距离函数的分析

运用SBM方向距离函数和Luenberger生产率指标测度2006年～2010年我国42家寿险公司的经营效率和全要素生产率变动,并对其进行了分解。研究结果发现:在考虑赔付支出的情况下,我国寿险业的平均无效率值为46.74%,其中,中资寿险公司的无效率值为33.47%,外资公司为60.01%。中资寿险公司的效率值优于外资公司;寿险产品的同质化及较强的投资性属性,使得在投资环境疲弱的环境下,投资收益的无效率成为制约寿险业经营效率提升的重要原因;寿险业平均全要素生产率为23.8%,其中,中资寿险公司为77.31%,外资公司为-29.72%,规模扩张增速放缓导致的规模效率变化为负是影响寿险业全要素生产率提升的重要原因之一。本文据此提出相关政策建议。     

投资渠道多元化背景下寿险公司投资风险管控探析

近年来,我国寿险投资渠道开始逐步多元化,传统投资渠道的投资比例逐步变小,寿险公司投资债券、证券投资基金、股票等高风险投资产品的资金及其比例逐步增加。为了转变利润增长方式,提升我国寿险公司盈利能力,促进寿险公司由粗放型发展向集约型发展转变,寿险投资渠道多元化是一个必然的和必需的过程。投资渠道多元化在给寿险公司带来机遇的同时,也增大了寿险公司投资风险。对经济转轨时期投资渠道多元化背景下我国寿险公司面临的投资风险及其管控措施进行研究,十分必要。     

对非寿险银保业务发展的若干思考

我国非寿险银保业务发展明显落后于寿险银保业务的现状,与产险公司和银行的发展观念、非寿险产品的特点以及宏观经济政策等因素密切相关。随着我国国民经济的快速发展、新农村建设步伐的加快、银行业服务领域的多元化发展以及个人资产快速膨胀后对风险转移需求的不断扩大,非寿险银保合作前景将十分广阔。因此,产险公司和银行应积极创新观念、产品和技术,从战略高度上推进非寿险银保合作,从源头上提升非寿险银保业务的核心竞争力,从基础上强化非寿险银保合作的系统支持力,进而促进非寿险银保业务的可持续发展。     

人寿保险核赔防诈调查处理六法

在我国,人寿保险业务一直保持着高速发展的势头,多种经济成份的寿险公司不断增加,寿险公司的各类产品层出不穷,民众的保险意识明显增强,人们购买寿险产品的消费能力迅速提高。人们购买寿险产品一是为了转嫁风险使家庭或个人多一份保障;二是为了投资增值。从寿险业务数据统计分析,前者的需求超过后者。天有不测风云,人有旦夕祸福,既然有人买保险,当然肯定有人会出险,因此,寿险公司的理赔工作显得尤为重要,这是保险宗旨具体体现的一个主要方面。 寿险公司的理赔工作有多项环节,其中核赔调查处理是较关     

寿险公司业务的保障属性对经营绩效的影响

目前,寿险业面临着深化改革的难题,不少寿险公司的发展也遇到了困难,在此背景下,一些偏离"保险姓保"政策导向的寿险公司的经营绩效表现不佳,且抗风险能力堪忧.回归"保障"能否改善寿险公司的经营绩效,进而增强寿险业整体的抗风险能力,成为当下亟待研究的问题.本文聚焦寿险公司业务保障属性强弱对其经营绩效的影响,采用"保险风险占比"指标来度量寿险公司业务的保障属性强弱,综合构建寿险公司绩效评价方式,选取61家寿险公司作为样本,组成非平衡面板数据,采用固定效用模型、多项Logit模型进行实证分析,并采用更换模型法和子样本回归法对实证结果进行稳健性检验.研究发现,寿险公司业务的保障属性强会对其经营绩效产生显著正向影响.具体而言,寿险公司业务保障属性越强,其盈利能力越强,同时其经营稳健性越好,具体表现为该公司的投资风险、退保风险、偿付风险和流动性风险越低.基于此,本文提出相关的监管政策建议和寿险公司经营战略建议.     

Bayesian Premium Rating with Latent Structure

We propose a fully Bayesian approach to non-life risk premium rating, based on hierarchical models with latent variables for both claim frequency and claim size. Inference is based on the joint posterior distribution and is performed by Markov Chain Monte Carlo. Rather than plug-in point estimates of all unknown parameters, we take into account all sources of uncertainty simultaneously when the model is used to predict claims and estimate risk premiums. Several models are fitted to both a simulated dataset and a small portfolio regarding theft from cars. We show that interaction among latent variables can improve predictions significantly. We also investigate when interaction is not necessary. We compare our results with those obtained under a standard generalized linear model and show through numerical simulation that geographically located and spatially interacting latent variables can successfully compensate for missing covariates. However, when applied to the real portfolio data, the proposed models are not better than standard models due to the lack of spatial structure in the data.     

The development of the group accounts disclosure system in Japan

The Japanese disclosure system of consolidated statements was introduced in 1977 and extensively revised in 1997. The role of the bureaucracy has been significant in these developments and seems to be part of Japan's closed culture. However, other explanations could also be applied. In particular, although Japanese firms opposed such disclosures on the basis of preparation costs, the Japanese government had to modernize the disclosure system, including consolidation, in order to develop the securities market regardless of an individual company's interests.     

Moments of Compound Mixed Poisson Distributions

Recursive formulae are derived for the evaluation of the moments and the descending factorial moments about a point n of mixed Poisson and compound mixed Poisson distributions, in the case where the derivative of the logarithm of the mixing density can be written as a ratio of polynomials. As byproduct, we also obtain recursive formulae for the evaluation of the moments about the origin, central moments, descending and ascending factorial moments of these distributions. Examples are also presented for a number of mixing densities.     

The designing of corporate accounting law in Japan after the Second World War

After the Second World War, during the neutralization of the controlled economy of wartime Japan, a design for a Corporate Accounting Law was elaborated by the Investigation Committee on the Business Accounting System. The Investigation Committee tried to establish not only new business accounting standards but also a central and independent administrative organ of corporate accounting regulation on the basis of the Corporate Accounting Law. The Corporate Accounting Law was expected to lay the legal foundation of the new corporate accounting regulation regime in Japan. Nevertheless, even though the original design of the fundamental accounting law was never realized, it should be considered the starting point for our understanding of external accounting history in post-war Japan.     

The deliberation around accounting techniques: accounting for depreciation and foreign exchange in an Indian jute company, 1870-1900

This paper examines the way two accounting techniques, namely depreciation and foreign exchange, were deliberated on, between 1870 and 1900, in an Indian jute company whose shareholders resided in the UK. The arena for these deliberations was the conflictual relationship between controlling and non-controlling shareholders as to how best to account for depreciation and foreign exchange especially when the particular accountings affected distributional issues such as the dividend decision. The purpose of this paper is to analyse and explain the processes by which a company's accounting practices emerge and develop as a contest between different interests. Accounting framed the parameters of the deliberations and provided the language of power and dissent. The paper uses a rich archive that includes narrative and accounting material.

Pricing Dynamic Insurance Risks Using the Principle of Equivalent Utility

We introduce an expected utility approach to price insurance risks in a dynamic financial market setting. The valuation method is based on comparing the maximal expected utility functions with and without incorporating the insurance product, as in the classical principle of equivalent utility. The pricing mechanism relies heavily on risk preferences and yields two reservation prices - one each for the underwriter and buyer of the contract. The framework is rather general and applies to a number of applications that we extensively analyze.

International harmonization of Japanese accounting standards

Historically, Japanese accounting standards have been quite distinct from International Accounting Standards (IASs) which have been perceived as being modelled on British-American accounting standards. However, in the 1990s, after the publication of E32 in 1989 and the IASC-IOSCO Agreement in 1995, the Business Accounting Deliberation Committee (BADC), the standards-setting body in Japan, has pursued a policy of harmonization with IASs. Accounting standards relating to consolidated financial statements of companies that make cross-border offerings of securities or operate worldwide are being revised drastically. This paper focuses on the development of international accounting harmonization and its impact on Japan.
