英文摘要:
We solve explicitly a two-dimensional singular control problem of finite fuel type for infinite time horizon. The problem stems from the optimal liquidation of an asset position in a financial market with multiplicative and transient price impact. Liquidity is stochastic in that the volume effect process, which determines the inter-temporal resilience of the market in spirit of Predoiu, Shaikhet and Shreve (2011), is taken to be stochastic, being driven by own random noise. The optimal control is obtained as the local time of a diffusion process reflected at a non-constant free boundary. To solve the HJB variational inequality and prove optimality, we need a combination of probabilistic arguments and calculus of variations methods, involving Laplace transforms of inverse local times for diffusions reflected at elastic boundaries.

中文摘要:
我们显式地解决了无限时间范围内有限燃料类型的二维奇异控制问题。这个问题源于金融市场中资产头寸的最优清算,该资产头寸具有乘性和暂时性的价格影响。流动性是随机的,因为根据Predoiu、Shaikhet和Shreve(2011)的精神,决定市场跨期弹性的量效应过程被认为是随机的,由自身的随机噪声驱动。最优控制是扩散过程在非恒定自由边界上的局部时间。为了求解HJB变分不等式并证明其最优性,我们需要结合概率参数和变分法,包括弹性边界上反射扩散的逆局部时间拉普拉斯变换。
