Nonstationary ARCH and GARCH with t-Distributed Innovations

Consistency and asymptotic normality are established for the maximum likelihood estimators in the nonstationary ARCH and GARCH models with general t-distributed innovations. The results hold for joint estimation of (G)ARCH effects and the degrees of freedom parameter parametrizing the t-distribution. With T denoting sample size, square root T-convergence is shown to hold with closed form expressions for the multivariate covariances.
