This paper revisits Parks' seminal work on the time series relationship bet
ween inflation and relative price variability. The results reported show th
at a significant positive association is obtained allowing for an asymmetri
cal response of relative prices to episodes of positive and negative inflat
ion. This finding is :maintained after excluding oil shock years, extending
Parks' original sample to 1996, using an alternative data set and allowing
for a higher degree of disaggregation.
