Estimating risks of European option books using neural stochastic differential equation market models
The authors investigate how arbitrage-free neural stochastic differential equation market models can produce realistic scenarios for the joint dynamics of multiple European options on a single underlying and demonstrate how they can be used as a risk…
Nonconvex noncash risk measures
This paper looks at nonconvex, noncash risk measures with p-norm (1 ≤ p ≤ ∞) for nonweak cone-type acceptable sets.
Three ways to improve the systemic risk analysis of the Central and Eastern European region using SRISK and CoVaR
This paper proposes three modifications to two well-established measures of systemic risk, SRISK and CoVaR.
A numerical approach to the risk capital allocation problem
The aim of this paper is to use a model-free, nonparametric approach based on the method of maximum entropy in the mean to solve the capital risk allocation problem.
Risk measures: a generalization from the univariate to the matrix-variate
This paper develops a method for estimating value-at-risk and conditional value-at-risk when the underlying risk factors follow a beta distribution in a univariate and a matrix-variate setting.
Optimal reinsurance with expectile under the Vajda condition
In this paper, the author revisits optimal reinsurance problems by minimizing the adjusted value of the liability of an insurer, which encompasses a risk margin. The risk margin is determined by expectile.
Cyber risk management: an actuarial point of view
This paper points out the peculiarities of cyber insurance contracts compared with the classical nonlife insurance contracts from both the insurer’s and the insured’s perspectives. The main actuarial principles that are fundamental to any valuation in a…
Backtesting expected shortfall: a simple recipe?
In this paper, the authors introduce a new ES backtesting framework based on the duality between coherent risk measures and scale-invariant performance measures.
Study of correlation impact on credit default swap margin using a GARCH–DCC-copula framework
In this paper, the authors establish generalized autoregressive conditional heteroscedasticity–dynamic conditional correlation (GARCH–DCC) and constant conditional correlation (CCC) copula model frameworks to study time-varying correlation among credit…
Static and dynamic risk capital allocations with the Euler rule
This paper studies the volatility of the Euler rule for capital allocation in static and dynamic empirical applications with a simulated history.
Forecasting value-at-risk
Alvin Stroyny and Tim Wilding build a dynamic risk framework for multi-asset global portfolios
Quantification of operational risk: statistical insights on coherent risk measures
In this paper, the authors review some of the existing methods used to quantify operational risks in the banking and insurance industries.
From log-optimal portfolio theory to risk measures: logarithmic expected shortfall
In this paper, the authors propose a modification of expected shortfall that does not treat all losses equally. We do this in order to represent the worries surrounding big drops that are typical of multiperiod investors.
The utility of Basel III rules on excessive violations of internal risk models
In this paper, the author looks at the efficacy of risk measures on energy markets and across several different stock market indexes, and calculates both the value-at-risk (VaR) and the expected shortfall (ES) on each of these data sets as well as on…
A note on the statistical robustness of risk measures
This paper focuses on the parametric estimators of risk measures and uses Hampel’s infinitesimal approach to derive the robustness properties.
Shortfall deviation risk: an alternative for risk measurement
In this paper, the authors propose the SDR risk measure to consider the degree of dispersion of an extreme loss in addition to its expected value.
Comparing risk measures when aggregating market risk and credit risk using different copulas
The authors of this paper simulate realistic total bank return distributions by means of a top-down copula approach for different parameter settings.
Outperforming benchmarks with their derivatives: theory and empirical evidence
This paper looks for optimal explicit constructions and empirical tests in regards to pricing and hedging derivatives with coherent risk measures.
Optimal trading trajectories for algorithmic trading
This paper derives explicit formulas for the optimal implementation shortfall trading curve with linear and nonlinear market impact.
What is the best risk measure in practice? A comparison of standard measures
This paper revisits the properties of risk measures and checks VaR, ES and expectiles with regard to whether or not they enjoy these properties.
Which risk–collateral channels affect loan management?
This study examines the empirical relation between loan risk and the economic characteristics of collateral, each of which may be associated with the empirical dominance of different risk-collateral channels implied by economic theory.
