中文简介:
术语“系统性风险”通常表示由许多相互作用的代理组成的整个系统发生故障的风险。它是一种宏观性质,是由非线性相互作用所产生的。实际上,“系统性风险”已经意味着系统的故障不能完全由单个代理的故障来解释。相反,我们必须了解这种单一的故障是如何在整个系统中传播的,从而影响到其他代理。在这里,除了网络拓扑结构之外,诸如传染(类似于流行过程或放牧行为)、强化(流行趋势)和再分配(例如负载、压力或债务)等动态机制也发挥了相当大的作用。讨论的目的是在一个共同的框架中对一些现有的模型进行分类,首先,讨论一个特定的金融网络模型,然后,阐明系统崩溃的关键条件。
课程简介: The term ’systemic risk’ commonly denotes the risk that a whole system consisting of many interacting agents fails. It is a macroscopic property which emerges from the nonlinear interactions of agents. In fact, ’systemic risk’ already implies that the failure of the system cannot be fully explained by the failure of a single agent. Instead, one has to understand how such singular failures are able to spread through the whole system, affecting other agents. Here, in addition to network topology, dynamic mechanisms such as contagion (similar to epidemic processes or herding behavior), reinforcement (of prevailing trends), and redistribution (e.g. of load, stress, or debt) play a considerable role. The talk aims at categorizing some of the existing models in a common framework, first, and discussing a specific model of financial networks, afterwards, to elucidate the critical conditions for the breakdown of a system.
