We assess the predictive accuracy of a large number of multivariate volatility models in terms of pricing options on the Dow Jones Industrial Average. We measure the value of model sophistication in terms of dollar losses by considering a set 248 multivariate models that differ in their...

We study the impact of large cross-sections of contemporaneous aggregation of GARCH processes and of dynamic GARCH factor models. The results crucially depend on the shape of the cross-sectional distribution of the GARCH coefficients and on the cross-sectional dependence properties of the...

In this paper we study the effect of contemporaneous aggregation of heterogeneous GARCH processes as the cross-sectional size diverges to infinity. A complete statistical characterization of the limit aggregate is provided under general assumptions on the form and degree of heterogeneity of the...

forecast for the euro area in December 2000, forecasting inflation for the area has become of increasing importance. In this … study it is systematically analysed whether the forecasting performance of euro area inflation models can be improved by … aggregating forecasts of HICP subindices in comparison to forecasting total euro area inflation directly. The comparison is …
