| contents | This paper investigates the asymptotic behavior of higher-order conditional tail moments, which quantify the contribution of individual losses in the event of systemic collapse. The study is conducted within a framework comprising two investment portfolios experiencing dependent losses that follow convolution-equivalent distributions. The main results are encapsulated in two theorems: one addressing light-tailed losses with convolution-equivalent distributions and the other focusing on heavy-tailed losses with regularly varying distributions. Both results reveal that the asymptotic behavior remains robust regardless of the strength of dependence. Additionally, numerical simulations are performed under specific scenarios to validate the theoretical results. |
