Multivariate GARCH models: a survey
Abstract: This paper surveys the most important developments in multivariate ARCH-type modelling. It reviews the model specifications and inference methods, and identifies likely directions of future research.
Journal ArticleDOI
Value-at-risk for long and short trading positions
TL;DR: In this article, a collection of parametric models of the ARCH family based on the skewed Student distribution was used to model value-at-risk (VaR) for daily stock index returns.
Journal ArticleDOI
Modelling daily value-at-risk using realized volatility and arch type models
TL;DR: In this article, the authors compare the performance of a daily ARCH type model (which uses daily returns) with a model based on the daily realized volatility when the 1-day ahead value-at-risk (VaR) is to be computed.

TL;DR: In this article, the authors extract jumps and cojumps from three types of assets: stock index futures, bond futures, and exchange rates, and characterize the dynamics of these discontinuities and informally relate them to US macroeconomic releases before using limited dependent variable models to formally model how news surprises explain (co)jumps.
