保险衍生产品的最优交叉套期保值

Optimal cross hedging for insurance derivatives

Stefan Ankirchner, Peter Imkeller, Alexandre Popier

摘要:

我们认为保险衍生产品取决于外部物理风险过程,例如在低维气候模型中的温度。我们假设这一过程与可交易金融资产相关。我们从终端财富中推导出指数效用的最优策略,确定衍生品的无差别价格,并从多元化压力的角度解释它们。此外,我们检查标准的容许准则的最优投资策略。最后,我们比较了静态风险与保险衍生品的风险降低,由于动态投资到相关资产。我们表明,动态套期保值降低了风险规避熵风险措施的相关性的一个因素。

英文摘要:

We consider insurance derivatives depending on an external physical risk process, for example a temperature in a low dimensional climate model. We assume that this process is correlated with a tradable financial asset. We derive optimal strategies for exponential utility from terminal wealth, determine the indifference prices of the derivatives, and interpret them in terms of diversification pressure. Moreover we check the optimal investment strategies for standard admissibility criteria. Finally we compare the static risk connected with an insurance derivative to the reduced risk due to a dynamic investment into the correlated asset. We show that dynamic hedging reduces the risk aversion in terms of entropic risk measures by a factor related to the correlation.
