Research output: Chapter in Book/Report/Conference proceedingChapter (Book)Researchpeer-review


We study the influence of taking liquidity costs and market impact into account when hedging a contingent claim. In the continuous time setting and under the assumption of perfect replication, we derive a fully non-linear pricing partial differential equation, and characterize its parabolic nature according to the value of a numerical parameter interpreted as a relaxation coefficient for market impact. We also investigate the case of stochastic volatility models with pseudo-optimal strategies.
