谱负Lévy过程下幂相关期权的价值

The value of power-related options under spectrally negative Lévy processes

Jean-Philippe Aguilar

摘要:

我们提供了分析工具,定价权期权与异国情调的功能(上限或日志回报,差距选项.)在单边稳定或回火稳定过程驱动的指数Lévy模型的框架中。定价公式采用对数远期货币性和到期时间的幂的快速收敛序列的形式;这些序列通过在Mellin空间中的因子化积分表示获得,该表示通过$\mathbb{C}$或$\mathbb{C}^2$中的剩余进行评估。与数值方法和效率测试的比较也进行了讨论。

英文摘要:

We provide analytical tools for pricing power options with exotic features (capped or log payoffs, gap options ...) in the framework of exponential Lévy models driven by one-sided stable or tempered stable processes. Pricing formulas take the form of fast converging series of powers of the log-forward moneyness and of the time-to-maturity; these series are obtained via a factorized integral representation in the Mellin space evaluated by means of residues in $\mathbb{C}$ or $\mathbb{C}^2$. Comparisons with numerical methods and efficiency tests are also discussed.
