Measuring non-exchangeable tail dependence using tail copulas [PDF]

open access: yesASTIN Bulletin: The Journal of the International Actuarial Association, 2023
Quantifying tail dependence is an important issue in insurance and risk management. The prevalent tail dependence coefficient (TDC), however, is known to underestimate the degree of tail dependence and it does not capture non-exchangeable tail dependence

Discovering Intraday Tail Dependence Patterns via a Full-Range Tail Dependence Copula

open access: yesRisks, 2023
In this research, we employ a full-range tail dependence copula to capture the intraday dynamic tail dependence patterns of 30 s log returns among stocks in the US market in the year of 2020, when the market experienced a significant sell-off and a rally

Nonlinear tail dependence in cryptocurrency-stock market returns: The role of Bitcoin futures

open access: yesResearch in International Business and Finance, 2021
We investigate the median and tail dependence between cryptocurrency and stock market returns of BRICS and Developed countries using a newly developed nonparametric cumulative measure of dependence over the period January 4, 2016 – December 31, 2019 as ...

On Tail Dependence and Multifractality [PDF]

open access: yesMathematics, 2020
We study whether, and if yes then how, a varying auto-correlation structure in different parts of distributions is reflected in the multifractal properties of a dynamic process.

Tail Dependence between Crude Oil Volatility Index and WTI Oil Price Movements during the COVID-19 Pandemic

open access: yesEnergies, 2021
This study investigates the dependence between extreme returns of West Texas Intermediate (WTI) crude oil prices and the Crude Oil Volatility Index (OVX) changes as well as the predictive power of OVX to generate accurate Value at Risk (VaR) forecasts ...

Likelihood Inference for Factor Copula Models with Asymmetric Tail Dependence [PDF]

open access: yesEntropy
For multivariate non-Gaussian involving copulas, likelihood inference is dominated by the data in the middle, and fitted models might not be very good for joint tail inference, such as assessing the strength of tail dependence.

Extreme return-volume relationship in cryptocurrencies: Tail dependence analysis

open access: yesCogent Economics & Finance, 2020
We explore extreme return-volumes dependence among different cryptocurrencies such as Bitcoin, Ethereum, Ripple, and Litecoin by using the Copula approach. We use Student-t, Frank, Clayton, Survival Clayton, Gumbel, and SJC copulas. We filter out margins

TAIL DEPENDENCE OF OLS [PDF]

open access: yesEconometric Theory, 2021
This paper shows that if the errors in a multiple regression model are heavy-tailed, the ordinary least squares (OLS) estimators for the regression coefficients are tail-dependent.

Nonparametric Estimation of the Tail-Dependence Coefficient

open access: yesRevstat Statistical Journal, 2013
A common measure of tail dependence is the so-called tail-dependence coefficient. We present a nonparametric estimator of the tail-dependence coefficient and prove its strong consistency and asymptotic normality in the case of known marginal ...
