- Abstract
- This paper studies the short-term and long-term consequences of the COVID-19 pandemic for productivity in Europe. Aggregate and sectoral evidence is complemented by firm-level data-based findings obtained from a large micro-distributed exercise. Productivity trends during the COVID-19 pandemic differed from past trends. Labour productivity per hour worked temporarily increased, while productivity per employee declined across sectors given the widespread use of job retention schemes. The extensive margin of productivity growth was muted to some degree by the policy support granted to firms. Firm entries declined while firm exits increased much less than during previous crises. The pandemic had a significant impact on the intensive margin of productivity growth and led to a temporary drop in within-firm productivity per employee and increased reallocation. Job reallocation was productivity-enhancing but subdued compared to the Great Recession. As confirmed by a granular data analysis of the distribution of employment subsidies and loan guarantees and moratoria, job reallocation and also debt distribution and“zombie firm” prevalence were not significantly affected by the COVID-19 policy support. The pandemic and related lockdowns accelerated changes in consumer preferences and working habits with potential long-term effects. Generous government support muted the surge in unemployment and reduced permanent scarring effects.

- Abstract
- This paper introduces innovative, newly developed forward-looking indicators of negotiated wage growth in the euro area using data on collective bargaining agreements from seven countries: Germany, France, Italy, Spain, the Netherlands, Austria and Greece. The paper demonstrates how agreement-level data can be used to study drivers of aggregate negotiated wage growth, as well as monitor the breadth of wage increases and account for time-varying factors such as one-off payments, when assessing wage pressures. Lastly, the paper shows that the new indicators can provide reliable signals about current and future developments of wage pressures in the euro area while also serving as important cross-checking tools for negotiated wage growth forecasts.

- Abstract
- This paper documents five stylised facts relating to price adjustment in the euro area, using various micro price datasets collected in a period with relatively low and stable inflation. First, price changes are infrequent in the core sectors. On average, 12% of consumer prices change each month, falling to 8.5% when sales prices are excluded. The frequency of producer price adjustment is greater (25%), reflecting that the prices of intermediate goods and energy are more flexible. For both consumer and producer prices, cross-sectoral heterogeneity is more pronounced than cross-country heterogeneity. Second, price changes tend to be large and heterogeneous. For consumer prices, the typical absolute price change is about 10%, and the distribution of price changes shows a broad dispersion. For producer prices, the typical absolute price change is smaller, but nevertheless larger than inflation. Third, price setting is mildly state-dependent: the probability of price adjustment rises with the size of price misalignment, mainly reflecting idiosyncratic shocks, but it does not increase very sharply. Fourth, for both consumer and producer prices, the repricing rate showed no trend in the period 2005-19 but was more volatile in the short run. Fifth, small cyclical variations in frequency did not contribute much to fluctuations in aggregate inflation, which instead mainly reflected shifts in the average size of price changes. Consistent with idiosyncratic shocks as the main driver of price changes, aggregate disturbances affected inflation by shifting the relative number of firms increasing or decreasing their prices, rather than the size of price increases and decreases.

- Abstract
- This report discusses the role of the European Union’s full employment objective in the conduct of the ECB’s monetary policy. It first reviews a range of indicators of full employment, highlights the heterogeneity of labour market outcomes within different groups in the population and across countries, and documents the flatness of the Phillips curve in the euro area. In this context, it is stressed that labour market structures and trend labour market outcomes are primarily determined by national economic policies. The report then recalls that, in many circumstances, inflation and employment move together and pursuing price stability is conducive to supporting employment. However, in response to economic shocks that give rise to a temporary trade-off between employment and inflation stabilisation, the ECB’s medium-term orientation in pursuing price stability is shown to provide flexibility to contribute to the achievement of the EU’s full employment objective. Regarding the conduct of monetary policy in a low interest rate environment, model-based simulations suggest that history-dependent policy approaches − which have been proposed to overcome lasting shortfalls of inflation due to the effective lower bound on nominal interest rates by a more persistent policy response to disinflationary shocks − can help to bring employment closer to full employment, even though their effectiveness depends on the strength of the postulated expectations channels. Finally, the importance of employment income and wealth inequality in the transmission of monetary policy strengthens the case for more persistent or forceful easing policies (in pursuit of price stability) when interest rates are constrained by their lower bound.

- 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
- This paper provides evidence on the role of non-base wage components as a channel for firms to adjust labour costs in the event of adverse shocks. It uses data from a firm-level survey for 25 European countries that covers the period 2010–2013. We find that firms subject to nominal wage rigidities, which prevent them from adjusting base wages, are more likely to cut non-base wage components in order to adjust labour costs when needed. Firms thus use non-base wage components as a buffer to overcome base wage rigidity. We further show that while nonbase wage components exhibit some degree of downward rigidity, they do so to a lesser extent than base wages.

- Abstract
- This paper presents the main findings of a survey conducted on a sample of Portuguese firms. The main aim was to identify some relevant characteristics about the dynamics of prices and wages in Portugal. The most important conclusions are: i) changes to wages are more synchronized than changes to prices; ii) most wages are defined using inflation as a yardstick, even though there are no formal rules; iii) the wages of most workers are defined in terms of sector-related collective agreements; iv) a considerable proportion of workers receive wages above those been agreed under the collective agreement; v) firms make frequent use of other mechanisms to cut payroll costs as a way of overcoming the restrictions imposed by downward nominal wage rigidity.

- Abstract
- Infrequent price changes at the firm level are now well documented in the literature. However, a number of issues remain partly unaddressed. This paper contributes to the literature on price stickiness by investigating the lags of price adjustments to different types of shocks. We find that adjustment lags to cost and demand shocks vary with firm characteristics, namely the firm's cost structure, the type of pricing policy, and the type of good. We also document that firms react asymmetrically to demand and cost shocks, as well as to positive and negative shocks, and that the degree and direction of the asymmetry varies across firms.

- Abstract
- Thanks to recent findings based on survey data, it is now well known that firms differ from each other with respect to their price-reviewing strategies. While some firms review their prices at fixed intervals of time, others prefer to perform price revisions in response to changes in economic conditions. In order to explain this fact, some theories have been suggested in the literature. However, empirical evidence on the relative importance of the factors determining firms' different strategies is virtually non-existent. This paper contributes to filling this gap by investigating the factors that explain why firms follow time-, state- or time- and state-dependent price-reviewing rules. We find that firms' strategies vary with firm characteristics that have a bearing on the importance of information costs, the variability of the optimal price and the sensitivity of profits to non-optimal prices. Menu costs, however, do not seem to play a significant role.

- Abstract
- This paper brings together empirical research on price and wage dynamics for the Portuguese economy based both on micro and macro data. As regards firms' pricing behaviour the most noticeable finding is that prices in Portugal are somewhat less flexible than in the United States but more flexible than in the Euro Area. Regarding firms' wage setting practices, we uncover evidence favouring the hypothesis of aggregate and disaggregate wage flexibility. Despite the existence of mandatory minimum wages, the presence of binding wage floors and the general use of extension mechanisms, the firms still retain some ability to circumvent collective agreements via the mechanism of the wage cushion. The evidence also suggests that Portuguese wages behave in a fashion consistent with the wage curve literature, but the responsiveness of real wages to unemployment changes may have declined over the last decade.

- Abstract
- This paper presents new evidence on the patterns of price and wage adjustment in European firms and on the extent of nominal rigidities. It uses a unique dataset collected through a firm-level survey conducted in a broad range of countries and covering various sectors. Several conclusions are drawn from this evidence. Firms adjust wages less frequently than prices: the former tend to remain unchanged for about 15 months on average, the latter for around 10 months. The degree of price rigidity varies substantially across sectors and depends strongly on economic features, such as the intensity of competition, the exposure to foreign markets and the share of labour costs in total cost. Instead, country specificities, mostly related to the labour market institutional setting, are more relevant in characterising the pattern of wage adjustment. The latter exhibits also a substantial degree of time-dependence, as firms tend to concentrate wage changes in a specific month, mostly January in the majority of countries. Wage and price changes feed into each other at the micro level and there is a relationship between wage and price rigidity.

- Abstract
- This paper presents original evidence on price setting in the euro area at the individual level. We use micro data on consumer (CPI) and producer (PPI) prices, as well as survey information. Our main findings are: (i) prices in the euro area are sticky and more so than in the US; (ii) there is evidence of heterogeneity and of asymmetries in price setting behaviour; (iii) downward price rigidity is only slightly more marked than upward price rigidity and (iv) implicit or explicit contracts and coordination failure theories are important, whereas menu or information costs are judged much less relevant by firms.

- Abstract
- This paper analyses the results of a survey conducted by the Banco de Portugal with the main purpose of investigating firms' price setting behaviour. The evidence points to the presence of a considerable degree of price stickiness, which seems to be higher in services than in manufacturing. The presence of implicit contracts between firms and their customers under which the former pledge to stabilise their prices as a way to increase customers' loyalty is apparently the main reason that prevents firms from changing their prices more promptly. Other relevant sources of price stickiness were also found: coordination problems arising from the preference of firms not to change their prices unless their competitors do so, the constraint imposed by a high share of fixed costs, marginal costs that vary little when costs are an important determinant in pricing decisions or the presence of formal contracts that are costly to renegotiate.

- Abstract
- This study investigates the pricing behaviour of firms in the euro area on the basis of surveys conducted by nine Eurosystem national central banks, covering more than 11,000 firms. The results, robust across countries, show that firms operate in monopolistically competitive markets, where prices are mostly set following markup rules and where price discrimination is common. Around one-third of firms follow mainly time-dependent pricing rules while two thirds allow for elements of state-dependence. The majority of firms take into account past and expected economic developments in their pricing decisions. Price stickiness is mainly driven by customer relationships
