涂抹分布及其在金融市场中的应用

Smearing Distributions and their use in Financial Markets

Petr Jizba, Hagen Kleinert

摘要:

证明了具有任意哈密顿量和不同标度参数v(“方差”)的路径积分的叠加服从马尔可夫过程的Chapman-Kolmogorov关系当且仅当v的相应涂抹分布具有特定的函数形式.随后的“拖尾”分布大大简化了用于拖尾和非拖尾条件概率的福克-普朗克方程的耦合系统。给出了该方法在具有随机波动率的金融模型中的简单应用。

英文摘要:

It is shown that superpositions of path integrals with arbitrary Hamiltonians and different scaling parameters v ("variances") obey the Chapman-Kolmogorov relation for Markovian processes if and only if the corresponding smearing distributions for v have a specific functional form. Ensuing "smearing" distributions substantially simplify the coupled system of Fokker-Planck equations for smeared and un-smeared conditional probabilities. Simple application in financial models with stochastic volatility is presented.
