- Abstract
- Based on granular data at the product level, this paper looks at whether and how the euro area and the United States have modified their import sourcing strategies since 2016, the role played by geopolitical tensions and the potential impact on import prices. It considers two different, but not mutually exclusive, changes to sourcing strategies for a given product: (i) increasing the number of sourcing countries and (ii) reducing the import market share of the main supplier country. Data suggest that both regions have, on average, increased the number of sourcing countries, particularly for products that are mostly imported from “geopolitically distant” countries (based on UN General Assembly voting records). Broadening the number of supplier countries has come at a cost; however, it has affected only a small share of total imports, with modest implications for inflation and the terms of trade. At the same time, evidence of a reduction in the import share of the main supplier country is more mixed and is generally associated with a shift towards cheaper – but not necessarily geopolitically closer – countries, suggesting that cost considerations take precedence over supply chain resilience and national security concerns.

- 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
- The box provides an assessment of the impact of the pandemic on the exports of firms involved in global value chains (“GVC” firms), based on firm-level data for France. Following the outbreak of the pandemic, GVC firms, defined as firms that both export and import, faced disruptions in their supplies from source countries. These shortages of intermediate inputs traded via global value chains constrained firms’ production and exports. The weaker export performance of GVC firms relative to other exporters coincided with the emergence of supply bottlenecks, which suggests that these disruptions were a key factor holding back the performance of firms involved in global value chains. Estimates in this box suggest that these supply-side disruptions had a significant downward impact on exports in the euro area in 2020 and 2021.

- Abstract
- We assess the impact of the pandemic and the ensuing disruptions to global value chains (GVCs) on exporting firms. We find that firms’ participation in GVCs increased their vulnerability to the pandemic shock, in terms of export sales and probability of survival. Firms further downstream in GVCs were more severely affected by supply disruptions. At the same time, our results suggest that exporting firms benefited from sourcing their core inputs from different countries, supporting the hypothesis that diversification in global value chains fosters supply chain resilience.

- Abstract
- This paper provides an analysis of the impact of the COVID-19 pandemic on exporting firms, fo-cusing on the role of supply bottlenecks. Based on monthly transaction-level data for the universe of French exporters over the period January 2020-December 2021, we find that participation in global value chains increased firms’ vulnerability to the COVID-19 shock, in terms of both export perfor-mance and probability of survival in the export market, the negative impact of supply disruptions being higher for relatively more downstream firms. At the same time, the results suggest that export-ing firms benefited from sourcing of core inputs from different countries, supporting the hypothesis that diversification in global value chains fosters supply-chain resilience.

- Abstract
- The consensus back in 2008 – ten years after the introduction of the euro – was that the adoption of a common currency had made a limited impact of around 2% in total on the trade flows of the first wave of euro area countries (Baldwin et al., 2008). Since then, six more countries have joined the euro area, and firms have internationalised their production processes. These two phenomena are interrelated and may have changed the way the common currency affects the euro area economy. Therefore, with the common currency now into its third decade – and with more countries queuing to adopt it – this paper revisits the trade effects of the euro, focusing on the newer euro adopters (i.e. those countries that have adopted the euro since 2007) and their interaction with the first wave of euro area members via supply chains. The contribution of the paper is twofold. First, it revisits the estimated aggregate impact of the euro on euro area trade, as well as on trade within and between the two waves of adopters. Data on bilateral flows between 1990 and 2015 for an extended sample of countries to estimate a gravity equation indicate a significant trade impact, ranging between 4.3% and 6.3% in total on average, with the magnitude being the highest for exports from the second wave of adopters to the first wave of adopters. If a synthetic control approach (Abadie and Gardeazabal, 2003; Abadie et al., 2010) is used instead, the estimated gains associated with euro adoption are greater. In particular, exports of both intermediate and final products from countries belonging to the first wave of euro adopters to those belonging to the second wave are estimated to have increased by about 30% using this approach. The second contribution made by this paper relates to the channels through which trade might be affected by a currency union. This question is explored by looking separately at trade in intermediate goods and final products. While we find that trade gains were mainly driven by trade in intermediate goods among countries that adopted the currency earlier (5.3%), our results also show that the euro had a positive effect on the exports of final products from the second wave of adopters to other euro area countries. This effect is as high as 10.6% with the gravity model and 32% with the synthetic control approach. One of the reasons for the difference in the range of estimates between the two approaches might be that the gravity model can control for unobserved characteristics via fixed effects, while the synthetic control approach may fail to do so. These results suggest that the euro facilitated the establishment and expansion of international production chains in Europe. In turn, this is likely to have increased business cycle synchronisation in the euro area and to have supported market access for later adopters.

- Abstract
- The aim of this report is to foster a better understanding of past trends in, and drivers of, productivity growth in the countries of the European Union (EU) and of the interplay between productivity and monetary policy. To this end, a group of experts from 15 national central banks and the European Central Bank (ECB) joined forces and pooled data and expertise for more than 18 months to produce the report. Group members drew on the extensive research already conducted on productivity growth, including within the European System of Central Banks and in the context of the review of the ECB’s monetary policy strategy, and worked together to conduct new analyses.

- Abstract
- This paper assesses how globalisation has shaped the economic environment in which the ECB operates and discusses whether this warrants adjustments to the monetary policy strategy. The paper first looks at how trade and financial integration have evolved since the last strategy review in 2003. It then examines the effects of these developments on global productivity growth, the natural interest rate (r*), inflation trends and monetary transmission. While trade globalisation initially boosted productivity growth, this effect may be waning as trade integration slows and market contestability promotes a winner-takes-all environment. The impact of globalisation on r* has been ambiguous: downward pressures, fuelled by global demand for safe assets and an increase in the propensity to save against a background of rising inequality, are counteracted by upward pressures, from the boost to global productivity associated with greater trade integration. Headline inflation rates have become more synchronised globally, largely because commodity prices are increasingly determined by global factors. Meanwhile, core inflation rates show a lower degree of commonality. Globalisation has made a rather modest contribution to the synchronised fall in trend inflation across countries and contributed only moderately to the reduction in the responsiveness of inflation to changes in activity. Regarding monetary transmission, globalisation has made the role of the exchange rate more complex by introducing new mechanisms through which it affects financial conditions, real activity and price dynamics. Against the background of this discussion, the paper then examines the implications for the ECB’s monetary policy strategy. In doing so, it asks two questions. How is the ECB’s economic and monetary analysis affected by globalisation? And how does globalisation influence the choice of the ECB’s monetary policy objective and instruments? ...

- Abstract
- The paper provides an ex-post analysis of the determinants of within-country regional heterogeneity of the labour market impact of COVID-19. By focussing on the first wave of the pandemic in the four largest euro area economies, it finds that the propagation of the economic impact across regions cannot be explained by the spread of infections only. Instead, a region’s economic structure is a significant driver of the observed heterogeneity. Moreover, our results suggest that a region's trade relations, both within and across countries, represent a relevant indirect channel through which COVID-19 related disruptions affect regional economic activity. In this regard, the analysis depicts vulnerabilities arising from potential disruptions of the highly integrated EU supply chains.

- Abstract
- This box examines the drivers of intra-country regional differences in the economic impact of the coronavirus (COVID-19), as observed in the four largest euro area economies during the initial phase of the pandemic. More specifically, it discusses how the interaction between government containment measures, sectoral structure and trade linkages helps explain the intra-country regional variations in the labour market impact of the pandemic. It finds that the different economic impact across regions cannot be explained solely by the spread of infections, a region’s economic structure is also a key determinant. Moreover, the trade relations of a region, both within and across countries, are found to be an important indirect channel through which coronavirus-related disturbances affect regional economic activity, highlighting vulnerabilities which may arise from disruptions to highly integrated EU supply chains.

- Abstract
- Well-functioning economic structures are key for resilient and prospering euro area economies. The global financial and sovereign debt crises exposed the limited resilience of the euro area’s economic structures. Economic growth was masking underlying weaknesses in several euro area countries. With the inception of the crises, significant efforts have been undertaken by Member States individually and collectively to strengthen resilience of economic structures and the smooth functioning of the euro area. National fiscal policies were consolidated to keep the increase in government debt contained and structural reform momentum increased notably in the second decade, particularly in those countries most hit by the crisis. The strengthened national economic structures were supported by a reformed EU crisis and economic governance framework. However, overall economic structures in euro area countries are still not fully commensurate with the requirements of a monetary union. Moreover, remaining challenges, such as population ageing, low productivity and the implications of digitalisation, will need to be addressed to increase economic resilience and long-term growth.

- Abstract
- This paper illustrates the main features of the Labour Module of the CompNet dataset which provides indicators of firm growth over the period 1995-2012 across 17 EU (13 euro area) countries and 9 macro-sectors. It also includes information on a large set of micro-aggregated characteristics of firms growing at different speed such as their financial position and labour and total factor productivity. The paper shows that during the Great Recession the share of shrinking firms sharply increased in countries under stress, while firm growth slowed down in non-stressed countries. In the former, the construction sector suffered the most, while in the latter manufacturing and services related to transportation and storage were mainly affected, possibly as a result of the trade collapse. While we find that, all else equal, more productive firms had a higher probability of growing, the process of productivity-enhancing reallocation was muted during the Great Recession.

- Abstract
- Between the start of the economic and financial crisis in 2008, and early 2010, almost four million jobs were lost in the euro area. Employment began to rise again in the first half of 2011, but declined once more at the end of that year and remains at around three million workers below the pre-crisis level. However, in comparison with the severity of the fall in GDP, employment adjustment has been relatively muted at the aggregate euro area level, mostly due to significant labour hoarding in several euro area countries. While the crisis has, so far, had a more limited or shorter-lived impact in some euro area countries, in others dramatic changes in employment and unemployment rates have been observed and, indeed, more recent data tend to show the effects of a re-intensification of the crisis. The main objectives of this report are: (a) to understand the notable heterogeneity in the adjustment observed across euro area labour markets, ascertaining the role of the various shocks, labour market institutions and policy responses in shaping countries

- Abstract
- A small labour market model for the six largest euro area countries (Germany, France, Italy, Spain, the Netherlands, Belgium) is estimated in a state -space framework. The model entails, in the long run, four driving forces: a trend labour force component, a trend labour productivity component, a long-run inflation rate and a trend hours worked component. The short run dynamics is governed by a VAR model including six shocks. The state-space framework is convenient for the decomposition of endogenous variables in trends and cycles, for shock decomposition, for incorporating external judgement, and for running conditional projections. The forecast performance of the model is rather satisfactory. The model is used to carry out a policy experiment with the objective of investigating whether euro area countries differ in the labour market adjustment to a reduction in labour costs. Results suggest that, following the 2008-09 recession, moderate wage growth would significantly help delivering a more job-intense recovery.

- Abstract
- Overall, the prospects for a continued and reasonably fast real convergence process between the EU 8 countries and the euro area are good. However, the continuation of the rapid progress made by many EU 8 countries in the past cannot be taken for granted. In fact, in order to ensure that fast economic growth in the EU 8 countries remains sustainable, it is crucial for these economies to take appropriate policy action. First it is important to recall that sound macroeconomic policies including credible monetary policy and appropriate fiscal policy are essential to ensure the appropriate framework conditions for further growth and convergence. Second, they need to address structural labour market problems, in particular by reducing regional and skill mismatches. Third, they must make further efforts to improve the business environment, in order to ensure that the capital accumulation process continues and R&D investments increase. Many of the above-mentioned facets of growth-enhancing policy will also help to ensure a continued inflow of foreign direct investment (FDI), which in turn is expected to help accelerate the convergence process.

- Abstract
- This paper investigates the determinants of the service sector employment share in the EU-15, for the aggregate service sector, four sub-sectors and twelve service sector branches. Recently, both Europe and the US have experienced an increase in the share of service-related jobs in total employment. Although converging in all European countries, a significant gap in the growth of service jobs in Europe relative to the US persists. Understanding the main factors behind this gap is key to achieving higher employment levels in Europe. This paper focuses on the role of barriers in the EU-15 which may have hindered its ability to absorb labour supply and therefore to adjust efficiently to the sectoral reallocation of labour. We find that a crucial role in this process has been played by the institutional framework affecting the setting up of new businesses and by the mismatch between workers' skills and job vacancies.
