This study applies the time-varying volatility model to UK GDP deflators and compares it with the traditional inflation uncertainty measurement of relative price variability. The link between relative price variability and time-varying volatility is studied and established. Moreover, inflation uncertainty is found to be highly persistent in duration and plausibly asymmetric to previous shocks at both disaggregate and aggregate levels.
