摘要:Systemic risk (SR) is considered as the risk of collapse of an entire financial system, which has played a significant role in explaining the recent financial turmoils from the insurance and financial industries. Although there exists a very large number of SR measures in the literature, a simpler definition of SR by Acharya et al. (2012) is chosen to be discussed. We consider the asymptotic behavior of the SR for portfolio losses in the model allowing for heavy-tailed primary losses, which are equipped with a wide type of dependence structure. This risk model provides an ideal framework for addressing both heavy-tailedness and dependence. As some extensions, several simulation experiments are conducted. Comparing the asymptotic formulas with the traditional empirical estimators, our approach is superior to an empirical approach.
