We propose the use of convex combinations of parametric copulas as pair-copulas in high-dimensional vine copula models. By doing so, we circumvent the error-prone need to choose and estimate a parametric copula for each pair-copula in a vine model. We show in simulations that our proposed model...

In this paper, we analyze the accuracy of the copula-GARCH and Dynamic Conditional Correlation (DCC) models for forecasting the value-at-risk (VaR) and expected shortfall (ES) of bivariate portfolios. We then try to answer two questions: First, does the correlation-based DCC model outperform the...

The aim of the paper is to describe and compare the dynamics of linkages between stock markets during financial crises. We investigate similarities and differences between the patterns of changes in the conditional dependence structure during the 1997 Asian and 1998 Russian financial crises, and...
