A Remark on the Structure of Expectiles

Author

  • Freddy Delbaen

Abstract

Expectiles were defined using a minimisation principle. They form a special class of coherent risk measures. We will describe the scenario set and we will show that there is a most severe commonotonic risk measure that is smaller than the given expectile.
