It introduces entropic value at risk (EVaR) as a coherent risk measure, which is an upper … bound to the conditional value at risk (CVaR), and explores its generalization, relativistic value at risk (RLVaR), rooted …, particularly in scenarios of heightened risk and increased concentration, crucial for mitigating negative net performances during …

How can risk of a company be allocated to its divisions and attributed to risk factors? The Euler principle allows for … an economically justified allocation of risk to different divisions. We introduce a method that generalizes the Euler … principle to attribute risk to its driving factors when these factors affect losses in a nonlinear way. The method splits loss …

We examine how sensitive the new performance indexes incorporating high moments and disaster risk are to disaster risk …. The new performance indexes incorporating high moments and disaster risk are the Aumann-Serrano performance index and … underlying risk. We show, by numerical examples and empirical examples, how sensitive these indexes are to disaster risk …

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 its presence on the risk loading of the premium of a portfolio of insurance …

In this paper, the generalized Pareto distribution (GPD) copula approach is utilized to solve the conditional value-at-risk …-parametric kernel-smoothed interior and the parametric Pareto upper tail and (iii) Value-at-Risk (VaR) to quantify risk measure. The … minimizing CVaR measure and simulated copula returns combined outperforms the risk/return of domestic portfolios, such as the US …

The … GOP literature typically considers risk-neutral investors with an infinite investment horizon. In this paper, we compute … the optimal bet sizes in the more realistic setting of risk-averse investors with finite investment horizons. We find that …
