英文摘要:
  This paper assesses the hedge effectiveness of an index-based longevity swap and a longevity cap. Although swaps are a natural instrument for hedging longevity risk, derivatives with non-linear pay-offs, such as longevity caps, also provide downside protection. A tractable stochastic mortality model with age dependent drift and volatility is developed and analytical formulae for prices of these longevity derivatives are derived. Hedge effectiveness is considered for a hypothetical life annuity portfolio. The hedging of the life annuity portfolio is comprehensively assessed for a range of assumptions for the market price of longevity risk, the term to maturity of the hedging instruments, as well as the size of the underlying annuity portfolio. The model is calibrated using Australian mortality data. The results provide a comprehensive analysis of longevity hedging, highlighting the risk management benefits and costs of linear and nonlinear payoff structures.

中文摘要:
本文评估了基于指数的长寿互换和长寿上限的套期保值有效性。虽然掉期是对冲长寿风险的自然工具,但具有非线性回报的衍生品,如长寿上限,也提供了下行保护。建立了具有年龄相关漂移和波动性的可处理随机死亡率模型,并推导了这些寿命衍生产品的价格解析公式。对冲有效性是针对假设的人寿年金投资组合考虑的。针对长寿风险的市场价格、对冲工具的到期期限以及基础年金投资组合的规模等一系列假设,对人寿年金投资组合的对冲进行了全面评估。该模型使用澳大利亚的死亡率数据进行校准。研究结果对长寿保值进行了全面分析,突出了线性和非线性回报结构的风险管理收益和成本。
