This paper studies a coherent acceptability measure which is a negative coherent risk measure, in a multi-period model. When a coherent acceptability measure changes according to new information in the market, a time consistency plays an important role. The usual strong time consistency gives...

This paper studies a hedging problem of a contingent claim in a discrete time model. The contingent claim is hedged by one illiquid risky asset and the hedging error is measured by a quadratic criterion. In our model, trade does not always succeed and then trade times are not only discrete, but...

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...
