“…Such forecasts may be based on estimation of multivariate conditionally heteroscedastic (GARCH) models such as the BEKK model proposed by Engle and Kroner (1995), see e.g. Bauwens, Laurent, and Rombouts (2006) and Laurent, Rombouts, and Violante (2012). This is by now a well-known and much applied multivariate GARCH model; However, a drawback of the BEKK model, despite the fact that it is a very simple extension of the popular univariate GARCH model in Bollerslev (1987), is that it contains a large number of parameters even for a small number of series.…”

“…In light of this, one may reparametrize, or modify the BEKK model to obtain fewer parameters, while at the same time one may wish to consider a di¤erent estimation method from the usual Gaussian QMLE of all parameters. Examples of reducing the number of varying parameters in the optimization procedure include, for the BEKK model, diagonal-BEKK and scalar-BEKK, see Bauwens, Laurent, and Rombouts (2006).…”

“…Selain itu, perubahan dalam korelasi boleh menyebabkan kebolehcapaian kesan yang begitu jauh terutama yang berkaitan dengan lembaran imbangan dan implikasi modal (Lumsdaine 2009). Malah, salah satu isu yang sering kali diperdebatkan ialah kecenderungan korelasi meningkat dalam jangka masa panjang yang mungkin disebabkan oleh globalisasi atau liberalisasi pasaran kewangan (Bauwens, Laurent & Rombouts 2006). Di samping itu, terdapat juga bukti yang menunjukkan bahawa kebanyakan pasaran berintegrasi selepas membuka pasaran mereka kepada pelaburan asing.…”

“…Oleh itu, pengenalpastian sifat ini melalui rangka kerja pemodelan multivariat menuntut kepada penggunaan model empirikal yang lebih relevan (Bauwens et al 2006). Ini juga adalah kerana pemahaman tentang gelagat kemeruapan (varians) boleh membantu para penggubal dasar dalam meramal insiden yang bakal berlaku dan seterusnya menggubal dasar yang sesuai untuk kestabilan ekonomi sektor kewangan dan sektor benar.…”
