英文摘要:
We provide a new extension of Breiman\'s Theorem on computing tail probabilities of a product of random variables to a multivariate setting. In particular, we give a complete characterization of regular variation on cones in $[0,\\infty)^d$ under random linear transformations. This allows us to compute probabilities of a variety of tail events, which classical multivariate regularly varying models would report to be asymptotically negligible. We illustrate our findings with applications to risk assessment in financial systems and reinsurance markets under a bipartite network structure.

中文摘要:
我们提供了一个新的扩展布雷曼定理计算尾部概率的乘积随机变量的多元设置。特别地,我们给出了锥上正则变化的一个完整刻划$随机线性变换下的概率为[0,infty)^d$。这使我们能够计算各种尾部事件的概率,而经典的多变量规则变化模型将报告为渐近可忽略不计。我们通过将我们的发现应用于二部网络结构下金融系统和再保险市场的风险评估来说明我们的发现。
