An evaluation of the adequacy of Lévy and extreme value tail risk estimates
《Financial Innovation》2024年第1期1405-1430,共26页Sharif Mozumder M.Kabir Hassan M.Humayun Kabir 
This study investigates the simplicity and adequacy of tail-based risk measures—value-at-risk(VaR)and expected shortfall(ES)—when applied to tail targeting of the extreme value(EV)model.We implement Lévy-VaR and ES...
