文摘It is well known that the minimal superhedging price of a contingent claim is too high for practical use.In a continuous-time model uncertainty framework,we consider a relaxed hedging criterion based on acceptable shortfall risks.Combining existing aggregation and convex dual representation theorems,we derive duality results for the minimal price on the set of upper semicontinuous discounted claims.
