- Abstract
- The nominal effective exchange rate (EER) of a currency is an index of the trade-weighted average of its bilateral exchange rates vis-à-vis the currencies of selected trading partners, while the real EER is derived by adjusting the nominal index for relative prices or costs. The nominal EER provides a summary measure of a currency’s external value, while the real EER is the most commonly used indicator of the international price and cost competitiveness of an economy. Additionally, for all individual euro area countries, harmonised competitiveness indicators (HCIs) are published by the European Central Bank (ECB) based on the same methodology as the euro EERs. This paper describes how the calculation of the ECB’s EERs and HCIs has been enhanced to take into account in the underlying trade weights the evolution of international trade linkages and, in particular, the growing importance of trade in services. The paper includes an in-depth description of the methodology used to calculate these enhanced EERs and HCIs. In particular, it presents how to overcome the challenges arising from the inclusion of services trade, foremost in terms of data availability, with imputation and estimation techniques. Importantly, the ECB’s well-established methodology – which in particular accounts for competition faced by euro area exporters in third markets – did not have to be changed with the inclusion of services trade. Finally, the paper provides some evidence on the usefulness of the enhanced indicators for policymakers, economic analysts and the public at large.

- Abstract
- Consumer price inflation, as measured by the year-on-year increase in the Harmonised Index of Consumer Prices (HICP), is used by the European Central Bank (ECB) for assessing its monetary policy. The European Statistical System regularly introduces methodological improvements into this chain-linked price index in the linking month (December). If the outcome of such changes is a new series with a very different profile in December – either due to changed seasonality or one-off (sampling) effects – significant statistical distortions may arise when the new index series is chain-linked to the existing series. This paper explains the mechanism behind statistical distortions due to chain linking and provides some recent examples from European price statistics. Several alternative chain-linking practices, as well as recommendations for data users on how to deal with such statistical breaks in the HICP, are presented.
