This paper studies the common jump dynamics in natural gas futures and spot markets within a bivariate autoregressive jump intensity-GARCH framework (BARJI-GARCH). We particularly examine the role of weather as a short-run demand factor and inventory as a short-run supply factor in explaining...

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...
