Modelling exchange rates volatility with multivariate long-memory ARCH processes

Teyssière, Gilles - 1999 - Rev.

We consider two multivariate long-memory ARCH models, which extend the univariate long-memory ARCH models, we first consider a long-memory extension of the restricted constant conditional correlations (CCC) model introduced by Bollerslev (1990), and we propose a new unrestricted conditional...
