摘要:

In this talk we  provide a general mathematical framework for distributional transforms, which allows for many examples that  are used extensively  in the literature of finance,  economics and optimization.   We put a special focus on the   class of probability distortions, which is a fundamental tool in decision theory. As our main results, we characterize   distributional transforms satisfying various properties and this includes an equivalent set of conditions which forces a distributional transform to be a  probability distortion. As the first application, we  construct new risk measures  using distributional transforms.  Sufficient and necessary conditions are given to ensure the convexity or coherence of the generated risk measures. In the second application, we  introduce a new method for sensitivity analysis of risk measures based on composition groups of probability distortions. Finally, we construct probability distortions  describing a change of measures with an example in  option pricing.
