面对世界范围内长寿风险越来越严峻的趋势,长寿风险管理成为全世界面临的共同难题。近年来死亡率风险证券化引起人们的广泛关注,长寿债券作为死亡率风险证券化中最常用的一种方法,可以有效地将长寿风险转移至资本市场。本文通过对国外经典死亡率债券的比较,在离散型死亡率模型假设条件下,设计一支可调整上触碰点的触发型长寿债券,运用带永久跳跃的APC模型和风险立方方法对长寿债券进行定价。实证结果显示风险溢价的结果比较稳定,设置不同的初始上触碰点,风险溢价差异较大。  相似文献

长寿风险证券化可以把长寿风险转移到资本市场,有效管理养老保险公司的长寿风险。本文主要研究利息率与死亡率挂钩的逆生存债券,研究内容分为死亡率预测与债券定价两个部分。由于投资者对风险的偏好不同,本文利用百分位分层定价法对逆生存债券进行定价。数值分析展示了债券价格随利率变化的情况,共分四个层次,不同的分层对应不同的价格和风险,投资者可以根据自身的风险偏好选择不同的分层债券。最后就养老保险公司在长寿风险证券化方面存在的问题给出相关建议。  相似文献

动态死亡率下个人年金的长寿风险分析   总被引:1,自引:0,他引:1  
传统的精算定价方法假定死亡率是静态的,实际上死亡率是随时间而变动的具有动态不确定性的变量。在动态死亡率的框架下定量分析长寿风险对于个人年金产品定价的影响:引入Wang转换的风险定价方法度量长寿风险的市场价格,并运用模拟分析的方法分析长寿风险对个人年金定价的影响。最后,基于分析结果,就保险公司如何管理这一风险给出建议。  相似文献

本文基于均衡定价理论,利用CIR随机利率模型模拟无风险利率的变化情况,使用Copula函数建立复合触发机制下的联合分布函数,计算得出1~5年期的地震巨灾债券的价格。研究表明:风险触发反馈条件越严格,有效期越短,则风险暴露的程度越低,巨灾债券的价格就会越高;风险补偿能够提高巨灾债券的价格,使巨灾债券满足不同投资人的需求。相应的政策建议为确定相应的风险指数以有利于债券定价、发行多种类型的巨灾债券等。  相似文献

In this article, we consider the evolution of the post‐age‐60 mortality curve in the United Kingdom and its impact on the pricing of the risk associated with aggregate mortality improvements over time: so‐called longevity risk. We introduce a two‐factor stochastic model for the development of this curve through time. The first factor affects mortality‐rate dynamics at all ages in the same way, whereas the second factor affects mortality‐rate dynamics at higher ages much more than at lower ages. The article then examines the pricing of longevity bonds with different terms to maturity referenced to different cohorts. We find that longevity risk over relatively short time horizons is very low, but at horizons in excess of ten years it begins to pick up very rapidly. A key component of the article is the proposal and development of a method for calculating the market risk‐adjusted price of a longevity bond. The proposed adjustment includes not just an allowance for the underlying stochastic mortality, but also makes an allowance for parameter risk. We utilize the pricing information contained in the November 2004 European Investment Bank longevity bond to make inferences about the likely market prices of the risks in the model. Based on these, we investigate how future issues might be priced to ensure an absence of arbitrage between bonds with different characteristics.  相似文献

We develop a sequential pricing framework in a continuous time cash flow model allowing for repeated valuation of different cash flow claims. One claim is valued until a prespecified boundary is hit, which is subsequently used as the new valuation starting point for the next claim. This highly flexible pricing framework is applied to the pricing of rating-trigger step-up/-down corporate bonds, the coupon payments of which depend on the issuing company’s credit rating. We present a simple closed-form pricing solution for this type of bonds including both a step-up and step-down threshold, as well as a lower default boundary.  相似文献

Using self-made billionaire entrepreneurs in China as a proxy for large entrepreneurs, we examine the impact of institutional environment quality on the longevity of such entrepreneurs. While property rights institutions and contracting institutions are important in explaining macroeconomic growth and small firm growth, we find no evidence that they matter to the longevity of billionaire entrepreneurs. However, we find access to finance to be important to the longevity of billionaire entrepreneurs. Our results help better understand the relative importance of various institutional environment forces to the continuous success of billionaire entrepreneurs.  相似文献

This article investigates the latest developments in longevity-risk modelling, and explores the key risk management challenges for both the financial and insurance industries. The article discusses key definitions that are crucial for the enhancement of the way longevity risk is understood, providing a global view of the practical issues for longevity-linked insurance and pension products that have evolved concurrently with the steady increase in life expectancy since s. In addition, the article frames the recent and forthcoming developments that are expected to action industry-wide changes as more effective regulation, designed to better assess and efficiently manage inherited risks, is adopted. Simultaneously, the evolution of longevity is intensifying the need for capital markets to be used to manage and transfer the risk through what are known as Insurance-Linked Securities (ILS). Thus, the article will examine the emerging scenarios, and will finally highlight some important potential developments for longevity-risk management from a financial perspective with reference to the most relevant modelling and pricing practices in the banking industry.  相似文献

Government-issued longevity bonds would allow longevity risk to be shared efficiently and fairly between generations. In exchange for paying a longevity risk premium, the current generation of retirees can look to future generations to hedge their systematic longevity risk. Longevity bonds will lead to a more secure pension savings market, together with a more efficient annuity market. By issuing longevity bonds, governments can aid the establishment of reliable longevity indices and key price points on the longevity risk term structure and help the emerging capital market in longevity-linked instruments to build on this term structure with liquid longevity derivatives.  相似文献

Securitizing longevity/mortality risk can transfer longevity/mortality risk to capital markets. Modeling and forecasting mortality rate is key to pricing mortality‐linked securities. Catastrophic mortality and longevity jumps occur in historical data and have an important impact on security pricing. This article introduces a stochastic diffusion model with a double‐exponential jump diffusion process that captures both asymmetric rate jumps up and down and also cohort effect in mortality trends. The model exhibits calibration advantages and mathematical tractability while better fitting the data. The model provides a closed‐form pricing solution for J.P. Morgan’s q‐forward contract usable as a building block for hedging.  相似文献

This article explores the trade‐offs associated with government issuance of longevity bonds as a way of stimulating private annuity supply in the presence of aggregate mortality risk. We provide new calculations suggesting a 5 percent chance that aggregate mortality risk could ex post raise annuity costs for private insurers by as much as 5–10 percentage points, with the most likely effect based on historical patterns toward the lower end of that range. While we suspect that aggregate mortality risk does exert some upward pressure on annuity prices, evidence from private market pricing suggests that, to the extent that private insurers are accurately pricing this risk, the effect is less than 5 percentage points. We discuss ways that the private market can spread this risk, while emphasizing that the government has the unique ability to spread aggregate risk across generations. We note factors that might hamper such an efficient allocation of risk, including potential political incentives for the government to shift more than the optimal amount of risk onto future generations, and the possibility that government fiscal policy might allocate risk less efficiently within each generation than would private markets. We also discuss how large‐scale longevity bond issuance might affect government borrowing costs, as well as political economy aspects of how the proceeds from such a bond issuance might be used.  相似文献
