英文摘要:
European options can be priced by solving parabolic partial(-integro) differential equations under stochastic volatility and jump-diffusion models like Heston, Merton, and Bates models. American option prices can be obtained by solving linear complementary problems (LCPs) with the same operators. A finite difference discretization leads to a so-called full order model (FOM). Reduced order models (ROMs) are derived employing proper orthogonal decomposition (POD). The early exercise constraint of American options is enforced by a penalty on subset of grid points. The presented numerical experiments demonstrate that pricing with ROMs can be orders of magnitude faster within a given model parameter variation range.

中文摘要:
在随机波动和跳跃扩散模型(如Heston、Merton和Bates模型)下,欧式期权可以通过求解抛物偏微分方程(积分)来定价。美式期权价格可以通过使用相同的算子求解线性互补问题(LCP)得到。有限差分离散化导致所谓的全阶模型(FOM)。采用本征正交分解(POD)导出了降阶模型(ROM)。美式期权的早期行使约束是通过对网格点子集的惩罚来实施的。数值实验表明,在给定的模型参数变化范围内,使用ROM进行定价可以快几个数量级。
