英文摘要:
We discuss the systemic risk implied by the interbank exposures reconstructed with the maximum entropy method. The maximum entropy method severely underestimates the risk of interbank contagion by assuming a fully connected network, while in reality the structure of the interbank network is sparsely connected. Here, we formulate an algorithm for sparse network reconstruction, and we show numerically that it provides a more reliable estimation of the systemic risk.

中文摘要:
我们讨论了用最大熵方法重构的银行间风险敞口所隐含的系统性风险。最大熵方法通过假设一个完全连接的网络严重低估了银行间传染的风险,而实际上银行间网络的结构是稀疏连接的。在此,我们提出了一种稀疏网络重建算法,并通过数值计算表明,该算法可以更可靠地估计系统风险。
