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.

中文摘要:
我们提出了一个金融系统内金融机构之间依赖结构的动态模型,并构建了依赖和金融不稳定性的度量。利用联合信用迁移的马尔可夫结构,我们的模型允许信用评级的传染性同步跳跃,并提供了对依赖结构建模的灵活性。另一个关键方面是,拟议的措施考虑到了相互依存关系,并反映了金融机构随着时间的推移而不断变化的经济形势。在最后一部分,我们给出了几个例子,研究了各种依赖结构,并研究了它们的系统不稳定性度量。特别地,我们表明,在相同的马尔可夫链池中,具有不同依赖结构的模拟马尔可夫结构会产生不同的系统不稳定性序列。
