There is increasing demand for models of time-varying and non-Gaussian dependencies for mul- tivariate time-series. Available models suffer from the curse of dimensionality or restrictive assumptions on the parameters and the distribution. A promising class of models are the hierarchical...

In this paper, we use the skewed t copula with a DCC (Dynamic Conditional Correlation) model to capture the time-varying asymmetric tail dependence among MSCI US, Europe and Emerging markets. The empirical results show that it is important to take account of asymmetric tail dependence when...

The aim of this paper is to model the dependency among log-returns when security account prices are expressed in units of a well diversified world stock index. The paper uses the equi-weighted index EWI104s, calculated as the average of 104 world industry sector indices. The log-returns of its...
