农业巨灾保险体系研究：关于建立我国农业巨灾保险体系的思考

目前我国的农业巨灾保险体系尚未建立,保险在臣灾风险管理中的作用还没有得到充分发挥,巨灾损失只能由政府和社会来承担。推动农业巨灾保险制度建设、增强我国应对巨灾风险的能力,已成为一个亟待解决的问题。本文对我国农业巨灾保险体系的发展、以及其他国家的先进经验进行了介绍与分析,并对我国建立农业巨灾保险体系的制度模式进行了详细探讨。     

建立我国巨灾保险基金的思考

本文旨在从国际的视角,对世界各国的巨灾保险基金模式进行梳理分析,力图从中寻找适合我国国情的巨灾保险基金思路.本文首先论述中国建立巨灾保险基金的必要性;其次总结归纳国际巨灾保险基金的模式;最后对如何尽快建立我国巨灾保险基金提出了若干政策建议.     

制约我国农业巨灾保险体系建立的原因探析

建立农业巨灾保险体系意义重大。本文分析了制约农业巨灾保险体系建立的一般性和特殊性原因,提出探索农业巨灾保险体系的有效途径:加快推进法律政策体系建设;尽快组织力量开展我国农业巨灾保险制度框架设计;建立同业分保制度;强化农业巨灾风险管理的基础设施建设等。     

关于我国保险证券化前景的一些思考

保险证券化是保险公司联系金融市场的重要途径,是保险业保障偿付能力、分散经营风险的创新手段.上世纪90年代以来,保险证券化成为国际金融市场的一股趋势.现阶段我国的资本市场还处于以公司股票和政府债券为主的原始发展阶段,资产证券化发展刚刚萌芽但发展迅速.随着我国"一带一路"计划的发展,中国资本"走出去"的步伐加速,保险证券化对我国保险业提高偿付能力、扩大业务规模、实现国际经营越来越具有现实意义.     

保险资产管理及其风险规避

虽然近年来我国保险资产投资收益有了显著提高,但我国保险业的资产管理水平仍远远低于同期国际的平均水平。同时随着保险资金运用渠道的逐步拓宽,金融环境的变化等都在传递着各种金融风险,因此我们不但不能忽视保险的资产管理,更要对其存在的潜在风险做好充分的防范工作,在风险可控的前提下提高我国保险资产管理水平。     

发展我国网络保险的对策分析

虽然我国的网络保险还处于起步阶段,但已经开始迈出了向网络化发展的步伐.1997年11月28日,由中国保险学会牵头开办的中国保险信息网络已向公众开通运行,并已进入国际互联网,这表明我国保险业已经开始迈进网络大门,而1997年12月新华人寿在网上完成的第一份保单更是标志着我国的保险业已经搭上了网络快车.     

An integrated system for information security management with the unified framework

Information security management plays an essential role for drawing the roadmap of information security; thus, many theoretical methodologies and practical standards are brought into this domain. However, many standards and methodologies are too cumbersome to be adopted by an organization. Additionally, there is no unified framework to systematically handle the tedious tasks of information security management. This study’s primary goal is to design an integrated system for information security management (ISISM) that aims to use current methodologies and standards to solve the above-mentioned issues. Because business impact analysis and risk analysis are the most important areas within this domain, we carefully select the related methods and then integrate them into a unified framework, upon which the proposed ISISM depends. To achieve this outcome for this study, security requirement engineering is adopted, which enables the designed system to support system users in generating risk assessment reports with related information security policies.     

The art of risk management: the crucial role of the global art insurance industry in enabling risk and security

This article investigates the under-researched sphere of insurance. It uses empirical research data to focus on one case study, the London art world, to analyse how the global art insurance industry ‘does’ security and how it enables risk and security to be embraced. Examining how the industry plays a crucial role in the security of art and within the art world itself, the article argues that the global art insurance industry’s role is largely beneficial for the art world because by enabling risk to be embraced through insurance, its pre-crime and post-crime responses, and its influence ‘beyond’ insurance, it emboldens and fuels the dynamic, thriving global art world.     

Institutional investor information network,analyst forecasting and stock price crash risk

In this paper, we construct the information network of fund investors based on the theory of social relationship networks and examine its impact of fund information sharing with analysts on stock price crash risk. Our results show that private information sharing among institutional investors reduces crash risk. Further results show that fund information sharing can alleviate analyst optimism bias and improve analyst forecast accuracy, which further reduces stock price crash risk. Moreover, these identified effects are more pronounced in a bull market than a bear market. Our study contributes to the research on private information transmission in fund information networks, and provides a new perspective for recognizing the relationships among institutional investor behavior, analyst forecasting, and stock price crash risk.     

资产周期特性与保险公司资产配置策略

在竞争激烈的保险市场上,作为盈利的两大支柱之一,保险公司资产管理的能力日趋重要,而保险公司资产配置是保险资产管理的核心,其研究意义就显得尤为重要。本文首先给出保险资产配置的意义与总体原则,然后从保险资金的来源和特性入手,在详细分析了美国、中国不同经济周期和市场周期下大类资产风险收益特性的基础之上,给出保险公司资产负债管理和资产配置的战略决策建议。     

构建综合利用银行信息资源的网络安全体系

近几年，随着数据大集中的完成，银行已转向信息资源综合利用，电话银行、手机银行、网上银行方兴未艾，银行的网络系统不仅7×24小时传输银行关键业务数据，还传输管理信息和决策信息等重要数据。因此对网络的稳定性、可靠性具有相当高的要求，银行的网络安全建设日益显现出其重要性。为保证银行业务系统各类信息在存取、处理和传输中的完整性、机密性、可审计性和可用性，以及网络系统自身的可靠性、完整性和可用性，需多方位考虑设计网络系统的安全方案。网络系统安全方案的制定应尽可能全面和合理，并根据银行特有的多级管理和一级营业的管理特征，利用当前成熟和较为先进的网络安全技术，构建银行网络系统安全体系结构。本文详细分析了银行网络系统的安全风险问题，并在此基础上给出网络安全策略。[第一段]     

我国区域社会保障与商业保险协调度研究

本文构建了社会保障与商业保险协调度模型,定量研究了社会保障与商业保险的关系,并对模型进行了改进。结果显示:2005年~2010年我国绝大多数省份的协调等级都处于勉强协调和濒临失调的过渡区间,只有北京、山西、辽宁、上海和重庆在最近几年基本达到了初级协调,并且大部分省市的滞后类型为商业保险滞后型。基于上述分析,本文提出了促进社会保障与商业保险进一步协调发展的相关建议。     

Quantifying the risk-sharing welfare gains of social security

The welfare effects of intergenerational risk sharing through a pay-as-you-go social security system that is efficiently indexed to wages or interest rates are quantified. Comparing steady states, there are large welfare gains of being born into an economy with efficient risk sharing as compared to the current U.S. system. Efficient policy involves an increasingly risky net of tax income over the life cycle. When adjustment to steady state is taken into account, the welfare gains largely turn negative. The results are also compared and contrasted to the first best allocation.     

Cybersecurity insurance and risk-sharing

In today’s interconnected digital world, cybersecurity risks and resulting breaches are a fundamental concern to organizations and public policy setters. Accounting firms, as well as other firms providing risk advisory services, are concerned about their clients’ potential and actual breaches. Organizations cannot, however, eliminate all cybersecurity risks so as to achieve 100% security. Furthermore, at some point additional cybersecurity measures become more costly than the benefits from the incremental security. Thus, those responsible for preventing cybersecurity breaches within their organizations, as well as those providing risk advisory services to those organizations, need to think in terms of the cost-benefit aspects of cybersecurity investments. Besides investing in activities that prevent or mitigate the negative effects of cybersecurity breaches, organizations can invest in cybersecurity insurance as means of transferring some of the cybersecurity risks associated with potential future breaches.This paper provides a model for selecting the optimal set of cybersecurity insurance policies by a firm, given a finite number of policies being offered by one or more insurance companies. The optimal set of policies for the firm determined by this selection model can (and often does) contain at least three areas of possible losses not covered by the selected policies (called the Non-Coverage areas in this paper). By considering sets of insurance policies with three or more Non-Coverage areas, we show that a firm is often better able to address the frequently cited problems of high deductibles and low ceilings common in today’s cybersecurity insurance marketplace. Our selection model facilitates improved risk-sharing among cybersecurity insurance purchasers and sellers. As such, our model provides a basis for a more efficient cybersecurity insurance marketplace than currently exists. Our model is developed from the perspective of a firm purchasing the insurance policies (or the risk advisors guiding the firm) and assumes the firm’s objective in purchasing cybersecurity insurance is to minimize the sum of the costs of the premiums associated with the cybersecurity insurance policies selected and the sum of the expected losses not covered by the insurance policies.     

金融网络系统安全方案

随着计算机网络技术的普及，金融企业作为高新技术的受益者，在“单机—城域网—区域网—省域网—全国网—互联网”的发展过程中，数据逐级上收，网络规模逐步扩大，与之相应的网络安全也日趋重要。现在普遍存在的问题是重网络应用，轻网络安全管理。不少网络管理者认为金融企业网是脱离公网、相对封闭的网络系统，其安全威胁主要来自公网，而对于内部网的安全防范相对薄弱，存在很多网络安全隐患。一、网络安全隐患典型的省域网网络拓扑结构如图１所示。图１中，省分行数据中心受防火墙保护，可以有效防止来自地市分行的网络入侵；同样，地…
