This paper comprehensively discusses the dynamic relationship between commodities and commodity currencies, particularly during the U.S. quantitative easing (QEs), by integrating the generalized spillover index into a fractionally integrated VAR (FIVAR) model. Our empirical analyses reach the...

We introduce a multivariate multiplicative error model which is driven by componentspecific observation driven dynamics as well as a common latent autoregressive factor. The model is designed to explicitly account for (information driven) common factor dynamics as well as idiosyncratic effects...

Multiplicative error models (MEM) became a standard tool for modeling conditional durations of intraday transactions, realized volatilities and trading volumes. The parametric estimation of the corresponding multivariate model, the so-called vector MEM (VMEM), requires a specification of the...
