Conditional Tail Expectation and Premium Calculation under Asymmetric Loss

open access: yesAxioms, 2023
In this paper, we calculate premiums that are based on the Conditional Tail Expectation (CTE) and asymmetric loss functions to account for the risk of both underestimation and overestimation losses.

Sharp Probability Tail Estimates for Portfolio Credit Risk

open access: yesRisks, 2022
Portfolio credit risk is often concerned with the tail distribution of the total loss, defined to be the sum of default losses incurred from a collection of individual loans made out to the obligors.

Forecasting portfolio-Value-at-Risk with nonparametric lower tail dependence estimates [PDF]

open access: yesJournal of Banking & Finance, 2015
We propose to forecast the Value-at-Risk of bivariate portfolios using copulas which are calibrated on the basis of nonparametric sample estimates of the coefficient of lower tail dependence. We compare our proposed method to a conventional copula-GARCH model where the parameter of a Clayton copula is estimated via Canonical Maximum-Likelihood.

New stochastic comparisons based on tail value at risk measures [PDF]

open access: yesCommunications in Statistics - Theory and Methods, 2020
In this article we provide a new criterion for the comparison of claims, when we have conditional claims arising in stop loss contracts or contracts with franchise deductible. These stochastic comparisons are made on the basis of the Tail Value at Risk (also known as conditional tail expectation), just for a fixed level and beyond.

Semiparametric Value-At-Risk Estimation of Portfolios. A replication study of Dias (Journal of Banking & Finance, 2014)

open access: yesInternational Journal for Re-Views in Empirical Economics, 2019
This paper aims to replicate the semiparametric Value-At-Risk model by Dias (2014) and to test its legitimacy. The study confirms the superiority of semiparametric estimation over classical methods such as mixture normal and Student-t approximations in ...

Tail Risk Signal Detection through a Novel EGB2 Option Pricing Model

open access: yesMathematics, 2023
Connecting derivative pricing with tail risk management has become urgent for financial practice and academia. This paper proposes a novel option pricing model based on the exponential generalized beta of the second kind (EGB2) distribution.

Estimating Copula-Based Extension of Tail Value-at-Risk and Its Application in Insurance Claim

open access: yesRisks, 2022
Dependent Tail Value-at-Risk, abbreviated as DTVaR, is a copula-based extension of Tail Value-at-Risk (TVaR). This risk measure is an expectation of a target loss once the loss and its associated loss are above their respective quantiles but bounded ...

Estimation de mesures de risque pour des pluies extrêmes dans la région Cévennes-Vivarais [PDF]

open access: yes, 2015
International audienceMany risk measures can be found in the literature such as the Value-at-Risk and the Conditional Tail Expectation. In statistical terms, the Value-at-Risk is a upper quantile of the distribution of the variable of interest.

Tail risk modelling of cryptocurrencies, gold, non-fungible token, and stocks

open access: yesResearch in Globalization
We present tail risk analysis of cryptocurrencies (Bitcoin, Ethereum and Litecoin), non-fungible tokens, stocks (FTSE 100 and S&P 500) and Gold from November 12, 2017 to March 31, 2022 using conditional model-based Value-at-Risk (VaR).
