Sharp bounds on the expected shortfall for a sum of dependent random variables

Author

  • Puccetti, Giovanni

Abstract

Using a connection between the rearrangement algorithm introduced in Puccetti and Rüschendorf (2012) and convex order, we show how to compute the best-possible expected shortfall for the sum of d random variables having fixed marginal distributions.
