半静态市场中的最优投资和价格依赖

Optimal investment and price dependence in a semi-static market

Pietro Siorpaes

摘要:

本文研究了在一个半静态市场中,由局部有界半鞅模型描述的衍生证券和股票组成的最大化终端财富的期望效用的问题.利用定义在正实数线上的一般效用函数,我们首先研究了解的存在唯一性,然后考虑了效用最大化问题的输出对导数价格的依赖性,不仅研究了解的稳定性,而且还研究了解的可微性、单调性、凸性和极限性质.

英文摘要:

This paper studies the problem of maximizing expected utility from terminal wealth in a semi-static market composed of derivative securities, which we assume can be traded only at time zero, and of stocks, which can be traded continuously in time and are modeled as locally-bounded semi-martingales. Using a general utility function defined on the positive real line, we first study existence and uniqueness of the solution, and then we consider the dependence of the outputs of the utility maximization problem on the price of the derivatives, investigating not only stability but also differentiability, monotonicity, convexity and limiting properties.
