结合市场信息的经验似然法参数估计

Parameter Estimation using Empirical Likelihood combined with Market Information

Steven Kou, Tony Sit, Zhiliang Ying

摘要:

在过去的十年中,Levy过程的跳跃已经越来越受欢迎的衍生定价和风险管理目的的市场行为建模。Chan等人(2009年)介绍了使用经验似然方法,通过在大多数情况下容易获得的特征函数来估计各种扩散过程的参数。市场收益率系列用于估计。除了收益序列之外,市场上交易活跃的许多衍生品的价格也包含有关基础过程参数的信息。这种观察促使我们,在本文中,结合在市场上观察到的收益序列和相关的衍生品价格,以便提供一个更反映市场运动的估计,并实现效率的增益。在适当的正则条件下,建立了通常的渐近性质,包括相容性和渐近正态性。仿真和算例分析验证了该方法的可行性和有效性。

英文摘要:

During the last decade Levy processes with jumps have received increasing popularity for modelling market behaviour for both derviative pricing and risk management purposes. Chan et al. (2009) introduced the use of empirical likelihood methods to estimate the parameters of various diffusion processes via their characteristic functions which are readily avaiable in most cases. Return series from the market are used for estimation. In addition to the return series, there are many derivatives actively traded in the market whose prices also contain information about parameters of the underlying process. This observation motivates us, in this paper, to combine the return series and the associated derivative prices observed at the market so as to provide a more reflective estimation with respect to the market movement and achieve a gain of effciency. The usual asymptotic properties, including consistency and asymptotic normality, are established under suitable regularity conditions. Simulation and case studies are performed to demonstrate the feasibility and effectiveness of the proposed method.
