- Abstract
- Labour market developments are important drivers of the business cycle and are therefore closely watched by monetary policymakers. One process with significant macroeconomic ramifications are wage negotiations, where workers and employers bargain over the surplus income generated by an employment relationship. Bargaining power determines how this surplus is split between negotiating parties. However, it is unobserved, and can be driven by a number of factors. We exploit information about key events in Germany that are relevant for wage negotiations, such as labour strikes and the introduction of a minimum wage, to pinpoint changes in bargaining power. We find that such wage bargaining “shocks” are important drivers of unemployment and inflation, that their effect on wages is almost fully reflected in prices, and that they reduce the vacancy rate and increase firms' profits and the labour share of income in the short run, but not in the long run.

- Abstract
- We quantify the effects of wage bargaining shocks on macroeconomic aggregates using a structural vector auto-regression model for Germany. We identify exogenous variation in bargaining power from episodes of minimum wage introduction and industrial disputes. This narrative information disciplines the impulse responses to a wage bargaining shock of un-employment and output, and sharpens inference on the behaviour of other variables. The implied transmission mechanism is in line with the theoretical predictions of a large class of search and matching models. We also find that wage bargaining shocks explain a sizeable share of aggregate fluctuations in unemployment and inflation, that their pass-through to prices is very close to being full, and that they imply plausible dynamics for the vacancy rate, firms’ profits, and the labour share.

- Abstract
- The existence of nominal rigidities and inflation differentials between countries offers two of the main rationales for an inflation buffer in a monetary union where monetary policy is oriented towards an area-wide inflation objective. Evidence accumulated since 2003 suggests that nominal rigidities remain a prevalent feature of the euro area, with some differences as regards prices and wages. Price setting may have become more flexible and there is no evidence for any especially strong downward rigidities in price setting. At the same time, persistent downward nominal wage rigidity (DWR) provides a strong argument for a positive inflation buffer to “grease the wheels” of the euro area economy – also in order to avoid the risk of macroeconomic adjustments being managed in terms of quantities (unemployment) rather than prices when DWR is binding and particularly when productivity growth is low. Inflation differentials across euro area countries have tended to be small but persistent. For inflation dispersion in the euro area, the across countries has been more important than across regions, confirming that an inflation buffer might be especially important in a monetary union of different countries. Overall, inflation differentials were due to the rise of economic and financial imbalances in the first decade of the euro and the subsequent need for adjustment. Balassa-Samuelson effects which were highlighted in the 2003 strategy review were only a minor factor. By and large, the ECB’s inflation objective seems to have provided a sufficient margin to prevent countries from having to live with prolonged periods of excessively low inflation rates in the period 1999-2019. There were some exceptions in the second decade of the euro (from 2009-2019), when inflation in the euro area was, overall, substantially lower than during the first decade.

- Abstract
- 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.

- Abstract
- The coronavirus (COVID-19) pandemic triggered significant changes in household spending in 2020. These shifts are reflected in the 2021 HICP weights, and consequently, also in measured annual inflation. The impact of these new HICP weights on annual inflation is not insignificant and is also heterogenous across countries. Looking ahead, the full impact will most likely only materialise over the course of the year as the relative prices gradually change.

- Abstract
- We compare direct forecasts of HICP and HICP excluding energy and food in the euro area and five member countries to aggregated forecasts of their main components from large Bayesian VARs with a shared set of predictors. We focus on conditional point and density forecasts, in line with forecasting practices at many policy institutions. Our main findings are that point forecasts perform similarly using both approaches, whereas directly forecasting aggregate indices tends to yield better density forecasts. In the aftermath of the Great Financial Crisis, relative forecasting performance was typically only affected temporarily. Inflation forecasts made by Eurosystem/ECB staff perform similarly or slightly better than those from our models for the euro area.

- Abstract
- Despite notable improvements in the labour market since 2013, wage growth in the euro area was subdued and substantially overpredicted in 2013-17. This paper summarises the findings of an ESCB expert group on the reasons for low wage growth and provides comparable analyses on wage developments in the euro area as a whole and in individual EU countries. The paper finds that cyclical drivers, as captured by a standard Phillips curve, seem to explain much of the weakness in wage growth during this period, but not all of it. Going beyond the drivers included in standard Phillips curves, other factors are also found to have played a role, such as compositional effects, the possible non-linear reaction of wage growth to cyclical improvements, and structural and institutional factors. In order to increase the robustness of wage forecasts, the paper also proposes ready-to-use tools for cross-checking euro area wage growth forecasts based on wage Phillips curves. These are derived based on a comprehensive real-time forecast evaluation exercise

- Abstract
- Inflation projections are based on models, assumptions and expert judgement. These include assumptions regarding the future evolution of oil prices, which mainly affect energy prices. Oil prices and oil futures have moved down significantly since autumn 2018, below the assumptions of the December 2018 Eurosystem staff projections. This box documents the mechanical implications of this shift for the projections of the energy component of HICP inflation.

- Abstract
- This paper examines the process of adjustment of prices in Italy to determine whether nominal flexibility, measured by the frequency of price changes, has increased in the recent years of protracted stagnation and double-dip recession. The analysis is based on a large micro-level dataset of individual prices collected monthly by Istat from 2006 to 2013 for the Consumer Price Index. We find that both the percentage of prices adjusted monthly and the average size of the adjustment have risen significantly since the 1996-2001 period, in particular for downward changes. This greater flexibility is related in part to the spread of modern distribution structures. Our estimates further indicate that the recession has affected the price adjustment mechanism: for manufactures, price cuts have become larger and more frequent, while increases are more moderate; for services, both the frequency and the size of price increases have diminished.
