This article studies a replication of a contingent claim in an illiquid market. We represent the liquidity as a supply curve in a discrete time model. Because the trade price of the illiquid asset is a function of the trade size in this model, it is important whether the contingent claim is physically settled or settled in cash. In both cases, we give a condition where a replication strategy exists uniquely and show some properties of the replication strategy. Further we analyse the liquidity cost numerically.
