英文摘要:
This paper is a continuation of Ishitani and Kato (2015), in which we derived a continuous-time value function corresponding to an optimal execution problem with uncertain market impact as the limit of a discrete-time value function. Here, we investigate some properties of the derived value function. In particular, we show that the function is continuous and has the semigroup property, which is strongly related to the Hamilton-Jacobi-Bellman quasi-variational inequality. Moreover, we show that noise in market impact causes risk-neutral assessment to underestimate the impact cost. We also study typical examples under a log-linear/quadratic market impact function with Gamma-distributed noise.

中文摘要:
本文是Ishitani和Kato(2015)的延续,在这篇文章中,我们推导出了一个连续时间价值函数,对应于一个最优执行问题,该问题具有不确定的市场影响,作为离散时间价值函数的极限。这里,我们研究了派生值函数的一些性质。特别地,我们证明了该函数是连续的,并且具有半群性质,这与Hamilton-Jacobi-Bellman拟变分不等式密切相关。此外,我们还表明,市场影响中的噪声会导致风险中性评估低估影响成本。我们还研究了伽马分布噪声对数线性/二次市场影响函数下的典型例子。
