活动内容摘要:

We study the Neyman-Pearson theory for convex risk measures on L∞(μ). Without assuming that the level sets of penalty functions are weakly compact, a fixed representative pair (P∗,Q∗) is found by a new method different from the convex duality method. Then we show that the optimal tests are just the classical Neyman-Pearson tests between the representative probabilities P∗ and Q∗. Finally, we apply our results to a shortfall risk minimizing problem in an incomplete financial market.
