系统性风险与相关结构

Systemic Risk and the Dependence Structures

Yu-Sin Chang

摘要:

我们提出了一个动态模型的依赖结构的金融机构之间的金融系统,我们构建的依赖和金融不稳定性的措施。采用马尔可夫结构的联合信贷迁移,我们的模型允许传染性的同时跳跃的信用评级,并提供了灵活的建模依赖结构。另一个关键方面是,拟议的措施考虑到了相互依存性,并反映了随着金融机构的发展而不断变化的经济格局。在最后一部分中,我们给出了几个例子,我们研究了各种依赖结构,并研究了它们的系统不稳定性措施。特别是,我们表明,受相同的马尔可夫链池,不同的依赖结构的模拟马尔可夫结构产生不同的序列的系统不稳定性。

英文摘要:

We propose a dynamic model of dependence structure between financial institutions within a financial system and we construct measures for dependence and financial instability. Employing Markov structures of joint credit migrations, our model allows for contagious simultaneous jumps in credit ratings and provides flexibility in modeling dependence structures. Another key aspect is that the proposed measures consider the interdependence and reflect the changing economic landscape as financial institutions evolve over time. In the final part, we give several examples, where we study various dependence structures and investigate their systemic instability measures. In particular, we show that subject to the same pool of Markov chains, the simulated Markov structures with distinct dependence structures generate different sequences of systemic instability.
