英文摘要:
We propose a new methodology based on the Marshall-Olkin (MO) copula to model cross-border systemic risk. The proposed framework estimates the impact of the systematic and idiosyncratic components on systemic risk. Initially, we propose a maximum-likelihood method to estimate the parameter of the MO copula. In order to use the data on non-distressed banks for these estimates, we consider times to bank failures as censored samples. Hence, we propose an estimation procedure for the MO copula on censored data. The empirical evidence from European banks shows that the proposed censored model avoid possible underestimation of the contagion risk.

中文摘要:
我们提出了一种基于Marshall-Olkin(MO)copula的跨境系统性风险建模新方法。拟议的框架估计了系统性和特殊性因素对系统性风险的影响。首先,我们提出了一种最大似然方法来估计MO-copula的参数。为了使用非困境银行的数据进行这些估计,我们将银行倒闭的时间视为截尾样本。因此,我们提出了截尾数据上的MO copula估计方法。来自欧洲银行的经验证据表明,所提出的审查模型避免了对传染风险的可能低估。
