The methodology<br />

All of the above indicators can be expected to impact<br />

consumer price inflation with varying lags. For<br />

example, monetary conditions can be expected to<br />

affect prices with a lag of 1-2 years, according to<br />

ECB analysis 2 . Shocks to producer prices tend to be<br />

passed through more quickly, within 6-8 months.<br />

Furthermore, these relationships are not static over<br />

time; in general, the lags look to have shortened<br />

since the early 2000s.<br />

Chart 2: Core HICP and the CLIIP<br />

Core HICP (%y/y)<br />

We chose the optimal lag to apply to each of the<br />

variables according to our view of the current speed<br />

of transmission, using correlation coefficients as a<br />

guide.<br />

To prepare the series for aggregation, we remove<br />

any seasonality or trends, invert where appropriate,<br />

smooth the series using a Hodrick-Prescott filter, and<br />

normalise them (ie. such that they all have mean 0<br />

and standard deviation 1). The series are all given<br />

equal weight in the aggregation. The final stage is to<br />

transform the index such that it has a mean and<br />

standard deviation equal to core inflation, so that the<br />

index corresponds to an implied level of annual core<br />

inflation. The final CLIIP index is plotted against core<br />

inflation in Chart 2.<br />

Over the sample from January 2003 to present, the<br />

CLIIP has a correlation coefficient with core inflation of<br />

0.67. Between January 2009 and May 2012, the<br />

coefficient rises to 0.84. The components with the<br />

quickest transmission to core inflation are the consumer<br />

financial conditions survey and unemployment, both of<br />

which are incorporated into the index with a lag of six<br />

months. The index thus gives us a leading indicator for<br />

inflationary pressure that extends six months into the<br />

future.<br />

What does it tell us about inflation?<br />

Table 1 lists the components of the leading indicator<br />

for core inflation, their level at the last available CLIIP<br />

data point (which corresponds to expected inflation in<br />

January 2013) and whether each is positive,<br />

negative, or neutral for inflation on that horizon. The<br />

components are listed in normalised form, meaning<br />

that a value above zero implies a positive impact on<br />

core inflation; a negative number means a negative<br />

impact.<br />

As we might expect given that the eurozone<br />

economy is currently operating below potential,<br />

components indicative of economic slack and a<br />

subdued labour market are all inflation-negative: the<br />

level of unemployment, consumer expectations, and<br />

unit labour costs are all at levels consistent with<br />

disinflationary pressure.<br />

Financial and monetary conditions are also inflationnegative;<br />

given that the monetary policy transmission<br />

mechanism is still impaired, several years after the<br />

credit crunch, this is not surprising either.<br />

Recent large falls in the euro can be expected to<br />

push up import prices and, therefore, domestic<br />

inflation in the eurozone in the coming months,<br />

although at 0.2 – less than one standard deviation<br />

away from its the long-run average – the normalised<br />

level of the REER component suggests the effect will<br />
