Optimizing Expected Shortfall under an ℓ1 Constraint—An Analytic Approach [PDF]
Entropy, 2021 Expected Shortfall (ES), the average loss above a high quantile, is the current financial regulatory market risk measure. Its estimation and optimization are highly unstable against sample fluctuations and become impossible above a critical ratio r=N/T ...

Implementation of a Commitment Machine for an Adaptive and Robust Expected Shortfall Estimation [PDF]
Frontiers in Artificial Intelligence, 2021 This study proposes a metaheuristic for the selection of models among different Expected Shortfall (ES) estimation methods. The proposed approach, denominated “Commitment Machine” (CM), has a strong focus on assets cross-correlation and allows to measure

Managing Meteorological Risk through Expected Shortfall [PDF]
Risks, 2020 This paper focuses on weather derivatives as efficient risk management instruments and proposes a more advanced approach for their pricing. An “hybrid” contract is introduced, combining insurance properties, specifically tailored for the region under ...

Regression Based Expected Shortfall Backtesting [PDF]
Journal of Financial Econometrics, 2019 This paper introduces novel backtests for the risk measure Expected Shortfall (ES) following the testing idea of Mincer and Zarnowitz (1969). Estimating a regression framework for the ES stand-alone is infeasible, and thus, our tests are based on a joint

On the Shortfall of Tail-Based Entropy and Its Application to Capital Allocation [PDF]
EntropyWe introduce and study the shortfall of tail-based entropy (STE), a tail-sensitive risk functional that combines expected shortfall (ES) and tail-based entropy (TE).

Backtesting Expected Shortfall: a simple recipe? [PDF]
Journal of Risk, 2018 We propose a new backtesting framework for Expected Shortfall that could be used by the regulator. Instead of looking at the estimated capital reserve and the realised cash-flow separately, one could bind them into the secured position, for which risk ...

Expected Shortfall and Beyond [PDF]
Journal of Banking & Finance, 2002 Financial institutions have to allocate so-called "economic capital" in order to guarantee solvency to their clients and counter parties. Mathematically speaking, any methodology of allocating capital is a "risk measure", i.e.

On the coherence of Expected Shortfall [PDF]
Journal of Banking & Finance, 2001 Expected Shortfall (ES) in several variants has been proposed as remedy for the defi-ciencies of Value-at-Risk (VaR) which in general is not a coherent risk measure. In fact, most definitions of ES lead to the same results when applied to continuous loss

On Exactitude in Financial Regulation: Value-at-Risk, Expected Shortfall, and Expectiles
Risks, 2018 This article reviews two leading measures of financial risk and an emerging alternative. Embraced by the Basel accords, value-at-risk and expected shortfall are the leading measures of financial risk.
