Comparative Analyses of Expected Shortfall and Value-at-Risk: Their Estimation Error, Decomposition, and Optimization
We compare expected shortfall with value-at-risk (VaR) in three aspects: estimation errors, decomposition into risk factors, and optimization. We describe the advantages and the disadvantages of…
Value-at-risk versus expected shortfall: A practical perspective
Research Toward the Practical Application of Liquidity Risk Evaluation Methods
This paper proposes a practical framework for the quantification of Liquidity-adjusted Value at Risk ("L-VaR") incorporating the market liquidity of financial products. This framework incorporates…
Comparative Analyses of Expected Shortfall and Value-at-Risk (2): Expected Utility Maximization and Tail Risk
We compare expected shortfall and value-at-risk (VaR) in terms of consistency with expected utility maximization and elimination of tail risk. We use the concept of stochastic dominance in studying…
Comparative Analyses of Expected Shortfall and Value-at-Risk (3): Their Validity under Market Stress
In this paper, we compare value-at-risk (VaR) and expected shortfall under market stress. Assuming that the multivariate extreme value distribution represents asset returns under market stress, we…
On the Validity of Value-at-Risk: Comparative Analyses with Expected Shortfall
Value-at-risk (VaR) has become a standard measure used in financial risk management due to its conceptual simplicity, computational facility, and ready applicability. However, many authors claim that…
Comparative analyses of expected shortfall and value-at-risk under market stress 1
In this paper, we compare value-at-risk (VaR) and expected shortfall under market stress. Assuming that the multivariate extreme value distribution represents asset returns under market stress, we…
Comparative Analyses of Expected Shortfall and VaR : their estimation error , decomposition , and optimization
We compare expected shortfall with Value-at-Risk (VaR) in three aspects: estimation errors, decomposition into risk factors, and optimization. We describe the advantages and the disadvantages of…
On the Risk Capital Framework of Financial Institutions
In this paper, we consider the risk capital framework adopted by financial institutions. Specifically, we review the recent literature on this issue, and clarify the economic assumptions behind this…
