Empirical evidence suggests that unconditional variance of exchange rate return series is subject to occasional structural breaks that may induce spurious phenomenon of high persistence and long memory of volatility processes. In this paper, we investigate the effects of such breaks on estimated...

This article investigates out-of-sample performance of the naïve hedging strategy relative to that of the minimum variance hedging strategy, in which the covariance parameters are estimated from eighteen econometric models. Hedging performance is compared across twenty-four futures markets. Our...

Dynamic minimum variance hedge ratios (MVHRs) have been commonly estimated using Bivariate GARCH model that overlooks basis effect on the time-varying variance-covariance of spot and futures returns. This paper proposes an alternative specification of the BGARCH model in which the basis effect...
