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.
