具有均值回复跳跃扩散过程的能量衍生品的快速定价

Fast Pricing of Energy Derivatives with Mean-reverting Jump-diffusion Processes

Nicola Cufaro Petroni, Piergiacomo Sabino

摘要:

大多数能源和商品市场都表现出均值回归和偶尔的明显价格飙升,这导致了对衍生产品的需求,这些产品保护持有人免受高价的影响。为此,在本文中,我们提出了准确和快速的方法模拟的现货价格动态建模为指数的总和的Ornstein-Uhlenbeck和一个独立的纯跳跃过程,后者是由复合泊松过程(双边)指数分布的跳跃。最后将这些方法应用于不同跳跃扩散市场模型组合下的亚式期权、天然气储备和波动的定价,并强调了所提出方法的明显计算优势。

英文摘要:

Most energy and commodity markets exhibit mean-reversion and occasional distinctive price spikes, which results in demand for derivative products which protect the holder against high prices. To this end, in this paper we present exact and fast methodologies for the simulation of the spot price dynamics modeled as the exponential of the sum of an Ornstein-Uhlenbeck and an independent pure jump process, where the latter one is driven by a compound Poisson process with (bilateral) exponentially distributed jumps. These methodologies are finally applied to the pricing of Asian options, gas storages and swings under different combinations of jump-diffusion market models, and the apparent computational advantages of the proposed procedures are emphasized.
