We construct time-varying tail risk networks to investigate systemic risk spillovers in the Belt

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 …

We propose a new systemic risk index based on the interdependence of extreme downside
movements of stock returns using the cross-quantilogram and network analysis approach …

Green growth has become a critical driver in sustainability science. However, attaining a
steady state of green growth can be challenging in the face of exogenous economic shocks …

We assess the degree of connectedness among 16 metals that are critical for the production
of clean energy technologies. These commodities are the constituents of the Energy …

The interdependence, dynamics and riskiness of financial institutions are the key features
