Market-risk optimization among the developed and emerging markets with cvar measure and copula simulation
Trabelsi, Nader; Tiwari, Aviral Kumar - In: Risks : open access journal 7 (2019) 3/78, pp. 1-20
In this paper, the generalized Pareto distribution (GPD) copula approach is utilized to solve the conditional value …-at-risk (CVaR) portfolio problem. Particularly, this approach used (i) copula to model the complete linear and non … minimizing CVaR measure and simulated copula returns combined outperforms the risk/return of domestic portfolios, such as the US …

Choosing expected shortfall over VaR in Basel III using stochastic dominance
Chang, Chia-Lin; Jiménez-Martín, Juan-Ángel; … - 2015
Bank risk managers follow the Basel Committee on Banking Supervision (BCBS) recommendations that recently proposed shifting the quantitative risk metrics system from Value-at-Risk (VaR) to Expected Shortfall (ES). The Basel Committee on Banking Supervision (2013, p. 3) noted that: "a number of...

A stochastic dominance approach to the Basel III dilemma : expected shortfall or VaR?
Chang, Chia-Lin; Jiménez-Martín, Juan-Ángel; … - 2015
The Basel Committee on Banking Supervision (BCBS) (2013) recently proposed shifting the quantitative risk metrics system from Value-at-Risk (VaR) to Expected Shortfall (ES). The BCBS (2013) noted that - a number of weaknesses have been identified with using VaR for determining regulatory capital...

An academic response to Basel 3.5
Embrechts, Paul; Puccetti, Giovanni; Rüschendorf, Ludger; … - In: Risks : open access journal 2 (2014) 1, pp. 25-48
Recent crises in the financial industry have shown weaknesses in the modeling of Risk-Weighted Assets (RWAs). Relatively minor model changes may lead to substantial changes in the RWA numbers. Similar problems are encountered in the Value-at-Risk (VaR)-aggregation of risks. In this article, we...

The impact of systemic risk on the diversification benefits of a risk portfolio
Busse, Marc; Dacorogna, Michel M.; Katz, Marie - In: Risks : open access journal 2 (2014) 3, pp. 260-276
Risk diversification is the basis of insurance and investment. It is thus crucial to study the effects that could limit it. One of them is the existence of systemic risk that affects all of the policies at the same time. We introduce here a probabilistic approach to examine the consequences of...

Partially censored posterior for robust and efficient risk evaluation
Borowska, Agnieszka; Hoogerheide, Lennart; Koopman, Siem Jan - 2019
A novel approach to inference for a specific region of the predictive distribution is introduced. An important domain of application is accurate prediction of financial risk measures, where the area of interest is the left tail of the predictive density of logreturns. Our proposed approach...
