英文摘要:
We solve the superhedging problem for European options in a market with finite liquidity where trading has transient impact on prices, and possibly a permanent one in addition. Impact is multiplicative to ensure positive asset prices. Hedges and option prices depend on the physical and cash delivery specifications of the option settlement. For non-covered options, where impact at the inception and maturity dates matters, we characterize the superhedging price as a viscosity solution of a degenerate semilinear pde that can have gradient constraints. The non-linearity of the pde is governed by the transient nature of impact through a resilience function. For covered options, the pricing pde involves gamma constraints but is not affected by transience of impact. We use stochastic target techniques and geometric dynamic programming in reduced coordinates.

中文摘要:
我们解决了流动性有限的市场中欧式期权的超边缘问题,其中交易对价格有短暂的影响,并且可能是永久的影响。影响是倍增的,以确保积极的资产价格。对冲和期权价格取决于期权结算的实物和现金交付规范。对于初始和到期日的影响很重要的非覆盖期权,我们将超边缘价格描述为退化半线性偏微分方程的粘性解,该解可能具有梯度约束。pde的非线性由通过弹性函数的冲击瞬态特性决定。对于涵盖期权,定价pde涉及伽马约束,但不受影响的暂时性影响。我们在简化坐标系中使用随机目标技术和几何动态规划。
