This paper – which takes into consideration overall experience with the Harmonised Index of Consumer Prices (HICP) as well as the improvements made to this measure of inflation since 2003 – finds that the HICP continues to fulfil the prerequisites for the index underlying the ECB’s definition of price stability. Nonetheless, there is scope for enhancing the HICP, especially by including owner-occupied housing (OOH) using the net acquisitions approach. Filling this long-standing gap is of utmost importance to increase the coverage and cross-country comparability of the HICP. In addition to integrating OOH into the HICP, further improvements would be welcome in harmonisation, especially regarding the treatment of product replacement and quality adjustment. Such measures may also help reduce the measurement bias that still exists in the HICP. Overall, a knowledge gap concerning the exact size of the measurement bias of the HICP remains, which calls for further research. More generally, the paper also finds that auxiliary inflation measures can play an important role in the ECB’s economic and monetary analyses. This applies not only to analytical series including OOH, but also to measures of underlying inflation or a cost of living index.

Can the indicator of negotiated wage rates play an especially important role in assessing and forecasting wage dynamics at the current juncture? While the data on negotiated wages are available on a more timely basis, negotiated wage growth tends to only react with some lag to changes in labour market conditions, owing to the nature of the negotiation process, and the indicator is currently still dominated by wage agreements agreed prior to the pandemic. The main effects of the pandemic on negotiated wage growth are likely to become visible only from 2021 – when a substantial share of wage contracts in euro area countries is due to be renegotiated. Wage drift developments, in conjunction with information on hours worked and unemployment, can provide some indications regarding the environment in which these negotiations will take place. The availability of more granular data, for example on negotiated wage growth in different sectors, would be very helpful in analysing euro area wage developments in more detail.

This box reviews the impact of changes in indirect taxes on inflation developments in the euro area. In the past, increases in indirect taxes have tended to contribute positively to inflation in the euro area. However, the recent reductions in indirect taxes in response to the coronavirus (COVID-19) pandemic in several euro area countries, in particular in Germany, have not been seen before in the euro area on this scale. The impact they will have on inflation is surrounded by considerable uncertainty, but overall the pass-through is likely to be incomplete and to vary across sectors. In this respect, the September 2020 staff projections expect only a quite limited pass-through. The effects are nevertheless large enough to imply a slight V-shape profile for underlying inflation excluding the effects of changes in indirect taxes concealed in the annual numbers for HICPX, as well as a gradual increase between 2020 and 2022.
