基于风险测度最小化的衍生产品定价、套期保值与优化设计

Pricing, Hedging and Optimally Designing Derivatives Via Minimization of Risk Measures

Pauline Barrieu, Nicole El Karoui

摘要:

在完全市场框架下,一个未定权益的定价和套期保值问题有唯一解。当引入一些不完全性时,问题变得更加困难。在文献中已经采用了几种方法来提供一个令人满意的答案,这个问题,一个特定的选择标准。在本文中,为了定价和套期保值的不可交易的未定权益,我们首先开始一个(标准)的效用最大化问题,并最终与一个等价的风险度量最小化。这个对冲问题可以被看作是一个特殊的情况下,更一般的情况下,风险转移不同的代理人,其中之一,包括金融市场。为了提供建设性的答案,这个一般的最优风险转移问题,静态和动态的方法被认为是。当考虑一个动态的框架,我们的主要目的是找到一个静态和非常抽象的风险措施之间的权衡,因为我们更感兴趣的是易处理的问题和解释的动态风险措施,我们得到的,而不是最终的一般结果。因此,在介绍了一个一般的公理化方法,动态风险措施,我们涉及到动态版本的凸风险措施的倒向随机微分方程。

英文摘要:

The question of pricing and hedging a given contingent claim has a unique solution in a complete market framework. When some incompleteness is introduced, the problem becomes however more difficult. Several approaches have been adopted in the literature to provide a satisfactory answer to this problem, for a particular choice criterion. In this paper, in order to price and hedge a non-tradable contingent claim, we first start with a (standard) utility maximization problem and end up with an equivalent risk measure minimization. This hedging problem can be seen as a particular case of a more general situation of risk transfer between different agents, one of them consisting of the financial market. In order to provide constructive answers to this general optimal risk transfer problem, both static and dynamic approaches are considered. When considering a dynamic framework, our main purpose is to find a trade-off between static and very abstract risk measures as we are more interested in tractability issues and interpretations of the dynamic risk measures we obtain rather than the ultimate general results. Therefore, after introducing a general axiomatic approach to dynamic risk measures, we relate the dynamic version of convex risk measures to BSDEs.
