摘要:
本文刻画了由具有异质性持续程度的冲击所产生的动态关联性。利用频域技术,我们引入了识别瞬态和持续性平滑变化关联的度量方法。我们的方法能够检验此类动态关联的统计差异。我们记录了美国金融行业波动率之间瞬态与持续性关联的显著差异,认为它们追踪了异质性持续的系统性风险来源,因此可作为市场参与者的有用工具。
英文摘要:
This paper characterises dynamic linkages arising from shocks with heterogeneous degrees of persistence. Using frequency domain techniques, we introduce measures that identify smoothly varying links of a transitory and persistent nature. Our approach allows us to test for statistical differences in such dynamic links. We document substantial differences in transitory and persistent linkages among US financial industry volatilities, argue that they track heterogeneously persistent sources of systemic risk, and thus may serve as a useful tool for market participants.
