WebThe bivariate-threshold-excess and point process models are appropriate for modelling the markets’ risks. For modelling the extremal dependence however, given the same marginal threshold quantile, the point process has more access to the extreme observations due to its wider sphere of coverage than the bivariate-threshold-excess … WebGrier and Perry (1996) estimate a bivariate GARCH-M model of inflation and RPV, and show that inflation uncertainty dominates trend inflation as a predictor of RPV. This review suggests that the model generating the various aspects of inflation is an important measure for examining the relationship.
