英文摘要:
We study an optimal execution problem in illiquid markets with both instantaneous and persistent price impact and stochastic resilience when only absolutely continuous trading strategies are admissible. In our model the value function can be described by a three-dimensional system of backward stochastic differential equations (BSDE) with a singular terminal condition in one component. We prove existence and uniqueness of a solution to the BSDE system and characterize both the value function and the optimal strategy in terms of the unique solution to the BSDE system. Our existence proof is based on an asymptotic expansion of the BSDE system at the terminal time that allows us to express the system in terms of a equivalent system with finite terminal value but singular driver.

中文摘要:
我们研究了非流动市场中的一个最优执行问题,当仅允许绝对连续的交易策略时,该问题具有瞬时和持续的价格影响以及随机弹性。在我们的模型中,值函数可以用一个具有奇异终端条件的三维倒向随机微分方程(BSDE)系统来描述。我们证明了BSDE系统解的存在性和唯一性,并根据BSDE系统的唯一解刻画了值函数和最优策略。我们的存在性证明基于BSDE系统在终端时间的渐近展开,该展开允许我们将系统表示为具有有限终端值但奇异驱动的等效系统。
