英文摘要:
In this paper, we introduce quantile coherency to measure general dependence structures emerging in the joint distribution in the frequency domain and argue that this type of dependence is natural for economic time series but remains invisible when only the traditional analysis is employed. We define estimators which capture the general dependence structure, provide a detailed analysis of their asymptotic properties and discuss how to conduct inference for a general class of possibly nonlinear processes. In an empirical illustration we examine the dependence of bivariate stock market returns and shed new light on measurement of tail risk in financial markets. We also provide a modelling exercise to illustrate how applied researchers can benefit from using quantile coherency when assessing time series models.

中文摘要:
在本文中,我们引入分位数相干性来测量频域联合分布中出现的一般依赖结构,并认为这种类型的依赖对于经济时间序列是自然的,但在仅使用传统分析时仍然是不可见的。我们定义了捕获一般依赖结构的估计量,详细分析了它们的渐近性质,并讨论了如何对一类可能的非线性过程进行推理。在一个实证例子中,我们检验了二元股票市场回报率的依赖性,并对金融市场尾部风险的度量提供了新的思路。我们还提供了一个建模练习,以说明应用研究人员在评估时间序列模型时如何从使用分位数相关性中获益。
