This thesis studies multivariate risk spillovers at the high-dimensional market network level, as well as univariate extreme risk modelling at the asset level. The first chapter proposes a novel time series econometric method to measure high-dimensional directed and weighted market network structures. Direct and spillover effects at different horizons, between nodes and between groups, are measured in a unified framework. Using a similar network measurement framework, the second chapter investigates the relationship between stock illiquidity spillovers and the cross-section of expected returns. I find that central industries in illiquidity transmission networks earn higher average stock returns (around 4% per year) than other industries.The third chapter proposes a new Dynamic Stable GARCH model, which involves the use of stable distribution with time-dependent tail parameters to model and forecast tail risks in an extremely high volatility environment. We can differentiate extreme risks from normal market fluctuations with this model." --
