Both payoffs are expressed by the signed variance-optimal martingale measure. Our results are applied to the claim hedging under partial information.展开更多

文摘In this paper, we compare the performance of the optimal attainable payoffs (of a general claim) derived by the variance-optimal approach and the indifference argument under the mean-variance preference in an incomplete market. Both payoffs are expressed by the signed variance-optimal martingale measure. Our results are applied to the claim hedging under partial information.
