WebWe propose the Dynamic Asymmetric MGARCH (DAMGARCH) model that allows for time-varying asymmetry with spillover effects. The interactions between variances may depend both on a direct relation between the conditional variances (as in standard MGARCH models) and on spillover effects from the ... asymmetric GJR-GARCH of Glosten et al. … WebIn a GARCH model, this curve is symmetric and centered around ε t − 1 = 0. In the AGARCH model, the News Impact Curve is still symmetric, but is centered around ε t − 1 = γ. The type of asymmetric response discussed above is then associated with positive values of γ, which we generally find to be statistically significant. AGARCH(p,q)
