This paper analyzes volatility spillovers in multivariate GARCH-type models. We show that the cross-effects between the … conditional variances determine the persistence of the transmitted volatility innovations. In particular, the effect of a foreign … volatility innovation on a conditional variance is even more persistent than the effect of an own innovation unless it is offset …

The transmission mechanisms of volatility between markets can be characterized within a new Markov Switching bivariate …

. A state-dependent volatility spillover GARCH hedging strategy is developed to capture the regime switching global equity … volatility spillover effect. Empirical results show that the NFNE futures exhibit superior effectiveness as an instrument for …

In this paper we study new nonlinear GARCH models mainly designed for time series with highly persistent volatility …. For such series, conventional GARCH models have often proved unsatisfactory because they tend to exaggerate volatility … related to relatively infrequent changes in regime. Using the theory of Markov chains we provide sufficient conditions for the …
