, 2023 We propose an $\ell_1$-penalized estimator for high-dimensional models of Expected Shortfall (ES). The estimator is obtained as the solution to a least-squares problem for an auxiliary dependent variable, which is defined as a transformation of the dependent variable and a pre-estimated tail quantile.

Bootstrapping the Expected Shortfall
Theoretical Economics Letters, 2018 The expected shortfall is a popular risk measure in financial risk management. It is defined as the conditional expected loss given that the loss is greater than a given high quantile. We derive the asymptotic properties of the blocking bootstrap estimators for the expected shortfall of a stationary process under strong mixing conditions.
