|Abstract: ||The purpose of this paper is to measure the degree of persistence of the overall, core, food
and energy Harmonized Indexes of Consumer Prices for the European Monetary Zone (HICP-EAs) and
to identify its implications for decision-making in the private sector and in public policy.
Using a non-parametric approach, our results demonstrate the presence of a statistically significant
level of persistence in four HICP-EAs: headline, core, food and energy. Moreover, contrary to popular
belief, the core index does not reflect permanent price changes. We also find evidence that the food and
energy price indexes are more volatile and more persistent than the other two price indexes. Our
results also show a reduction in persistence for both the headline and the core price indexes after the
implementation of the single monetary policy, but not for food and energy.
These results have important implications for both the private sector and for policymakers who use
the core price index as a reference in their decision-making. In particular, core price index can lead to
erroneous perception of price movements.|
