保险公司偿付能力恶化预测研究

文章在分析公司财务预测研究方法应用前提的基础上,运用MDA模型和Logistic线性回归模型预测方法对我国保险公司偿付能力恶化进行预测研究。结果表明两个主流模型均能在保险公司偿付能力恶化前1~2年较好地进行预测,但是由于两类错估率的不同,MDA模型要优于Logistic模型。

Medical insurance with rank-dependent utility

Summary. A well-known result in the medical insurance literature is that zero co-insurance is never second-best for insurance contracts subject to moral hazard. We replace the usual expected utility assumption with a version of the rank-dependent utility (RDU) model that has greater experimental support. When consumers exhibit such preferences, we show that zero co-insurance may in fact be optimal, especially for low-risk consumers. Indeed, it is even possible that the first-best and second-best contracts are identical. In this case, there is no “market failure”, despite the informational asymmetry. We argue that these RDU results are in better accord with the empirical evidence from US health insurance markets.

Unemployment insurance: The role of electoral systems and regional labour markets

Levels of insurance against unemployment vary considerably across countries. Replacement rates, the ratio relating income from unemployment to what people earned when they were employed, are higher in countries with proportional electoral systems than in countries with majoritarian systems. Also, replacement rates are positively correlated with per capita income and negatively correlated with the countries' unemployment rates. I develop an electoral competition model that replicates these stylized facts.     

Taxation of Mobile Factors as Insurance under Uncertainty

This paper considers the effects of the taxation of mobile factors, i.e., capital, under uncertainty. The wages earned by residents of a jurisdiction are uncertain due to random shocks. Since the uncertain wages in a jurisdiction depend on the amount of mobile capital employed in the jurisdiction, and since taxation alters the quantity of capital employed, taxation affects the riskiness of uncertain wages. In particular, the taxation of capital moderates the fluctuation of uncertain wages, thereby providing insurance. For this reason, jurisdictions use distortionary capital taxation even if lump‐sum taxation is available. In addition, this insurance effect counteracts the tendency toward too low tax rates on capital arising from tax competition, and possibly improves the efficiency of tax competition.     

发展中国农业保险的对策分析

目前中国农业保险发展滞后,其原因主要有农民收入不高、农业保险保费收入低、农业保险的法律法规不够完善及农业保险组织体系不够健全,应提高农民收入、完善农业保险法律法规、建立健全农业保险组织体系,以促进中国农业保险业的发展。     

进城农民工社会保障的影响因素研究

缺乏明确的法律规定、不同制度模式之间难以互通互联及其自身的缺陷,是制约进城农民工参加社会保障的重要制度性因素;性别、城市工作年限、是否签订劳动合同、工资收入、所在城市等则是影响进城农民工参加社会保障的非制度性因素。从制度创新和强化执法等方面提出了政策建议。     

我国产险公司财务恶化预警——基于Logistic模型

如何准确评估保险公司财务并对财务恶化进行正确的预警．一直是国内外学界、业界及监管机构关注的热点问题之一。本文采用我国产险公司2002～2005年数据，通过Logistic模型找出对产险公司财务状况具有显着影响的各种因素．并利用事前概率与预测概率辨别出财务状况异常的产险公司，在错误成本允许的条件下，寻求最佳的监管资源配置。实证结果表明．在不同的监管标准下，衡量产险公司财务影响因素的显著程度有所差异。模型受检值以事前概率为标准较预测概率为好．且受检值的大小将会影响产险公司财务状况预测的结果。     

Does the Company Lawyer Have Your Back? A Brief Look at the Need for Personal Private Liability Insurance

There are four traditional uses of private personal liability insurance dating from the 1970s to the present (Hayes 1979; Sommers 2005) which pertain either to individuals or corporations. There is insurance to cover damage to rental cars, umbrella insurance to cover any injury to a guest at one’s home, insurance bought by corporations to cover potential corporate responsibility for actions of company representatives and insurance including misadventures with financial information and morally hazardous behavior as well as corporate required actions which are later deemed to be wrong or inappropriate. Employees need to find out if the employee manual provides for coverage for legal liabilities resulting out of performing job responsibilities. Due to a need to reduce company costs, many companies are reducing or eliminating coverage for employees for many types of actions. Private personal liability insurance gives you the peace of mind to know what you are covered for and for how long. Employee rights versus corporate budgets are at the core of this discussion.
