Inflation dynamics in Uganda : a quantile regression approach

Abstract

This paper considers the measurement of inflation persistence in Uganda and how this has changed over time within different quantiles. The measures of inflation include headline inflation and two measures of core inflation. The results suggest that while a unit root is found in many of the upper quantiles of headline inflation, there is evidence of mean reversion within the lower quantiles, which implies that large positive deviations influence the permanent behaviour of inflation. In addition, we find higher levels of persistence after 2006 and during the inflation-targeting period, where potential structural changes may have arisen within the regression quantiles.
