英文摘要:
We study super-replication of contingent claims in an illiquid market with model uncertainty. Illiquidity is captured by nonlinear transaction costs in discrete time and model uncertainty arises as our only assumption on stock price returns is that they are in a range specified by fixed volatility bounds. We provide a dual characterization of super-replication prices as a supremum of penalized expectations for the contingent claim\'s payoff. We also describe the scaling limit of this dual representation when the number of trading periods increases to infinity. Hence, this paper complements the results in [11] and [19] for the case of model uncertainty.

中文摘要:
研究了具有模型不确定性的非流动市场中未定权益的超复制问题。流动性不足是由离散时间内的非线性交易成本捕获的,由于我们对股票价格回报的唯一假设是,它们在固定波动率边界指定的范围内,因此模型不确定性产生。我们提供了超级复制价格的双重特征,作为未定权益回报的惩罚期望的上确界。我们还描述了当交易周期数增加到无穷大时,这种对偶表示的标度极限。因此,本文对[11]和[19]中关于模型不确定性的结果进行了补充。
