具有小交易费用的一般无差别定价

General indifference pricing with small transaction costs

Dylan Possamaï, Guillaume Royer

摘要:

研究了小交易费用下欧式期权的效用无差别价格。考虑到一般的设置允许消费和一般效用函数在最后时刻T,我们得到的效用无差别价格的渐近展开的功能的渐近展开的效用最大化问题,并没有欧洲未定权益。我们使用[54]和[48]中基于均匀化和黏性解开发的工具来表征这些膨胀。最后,我们更精确地研究了指数效用的例子,特别是在较弱的假设下恢复[6]的结果。

英文摘要:

We study the utility indifference price of a European option in the context of small transaction costs. Considering the general setup allowing consumption and a general utility function at final time T, we obtain an asymptotic expansion of the utility indifference price as a function of the asymptotic expansions of the utility maximization problems with and without the European contingent claim. We use the tools developed in [54] and [48] based on homogenization and viscosity solutions to characterize these expansions. Finally we study more precisely the example of exponential utilities, in particular recovering under weaker assumptions the results of [6].
