- Abstract
- The monitoring and analysis of the business cycle is a central element of inputs to monetary policy decision-making. This report contributes to the analysis of business cycles in the euro area in three dimensions. First, in terms of business cycle dating, it proposes automated procedures to characterise the business cycle situation of the euro area and its main components, across countries and sectors. Second, it investigates how business cycle synchronisation has evolved over the last 20 years. Third, it analyses business cycle drivers from several perspectives, including the financial and international dimension, interconnectedness, demand and supply. It also features an early analysis of the economic implications of the COVID-19 pandemic. Rather than reaching strong conclusions on the history of the euro area business cycle, the primary aim of the report is to promote sound methods and approaches that are part of ongoing enhancements of the analytical infrastructure designed to analyse hard-to-ascertain questions on the nature and characteristics of euro area business cycle dynamics.

- Abstract
- Purchasing Managers’ Index (PMI) surveys are insightful because PMIs are released in advance of official hard data and are typically strongly correlated with these. This Box reports that after losing some predictive capacity during pandemic-related lockdowns and reopenings, the euro area composite output PMI is once again a reliable timely indicator for nowcasting euro area real GDP growth.

- Abstract
- This paper shows that newspaper articles contain timely economic signals that can materially improve nowcasts of real GDP growth for the euro area. Our text data is drawn from fifteen popular European newspapers, that collectively represent the four largest Euro area economies, and are machine translated into English. Daily sentiment metrics are created from these news articles and we assess their value for nowcasting. By comparing to competitive and rigorous benchmarks, we find that newspaper text is helpful in nowcasting GDP growth especially in the first half of the quarter when other lower-frequency soft indicators are not available. The choice of the sentiment measure matters when tracking economic shocks such as the Great Recession and the Great Lockdown. Non-linear machine learning models can help capture extreme movements in growth, but require sufficient training data in order to be effective so become more useful later in our sample.

- Abstract
- This article reviews how policy institutions – international organisations and central banks – use big data and machine learning methods to analyse the business cycle. It provides different examples to show how big data and machine learning methods are particularly suitable for capturing large shocks and non-linearities in real time. The coronavirus crisis is a case in point, where big data have provided invaluable timely signals on the state of the economy, thus helping to track and assess economic activity, domestic demand and labour market developments in real time. Finally, the article discusses the main challenges faced by central banks when using non-standard data and methods and areas of further application to the work of central banks.

- Abstract
- The exceptional contraction in economic activity induced by the outbreak of the coronavirus (COVID-19) has warranted an update of the standard toolkit used to forecast euro area real GDP in real time. This box describes the adjustments and the additions to the standard toolkit developed by ECB staff to account for the dramatic change in statistical and economic relationships due to COVID-19. The use of each individual tool is subject to a considerable degree of judgment as to the type of adjustment needed to best capture the sharp movements in economic activity. These tools have provided helpful insights into forecasting euro area real GDP in real time, even if they imply some shortcomings.

- Abstract
- We propose a granular framework that makes use of advanced statistical methods to approximate developments in economy-wide expected corporate earnings. In particular, we evaluate the dynamic network structure of stock returns in the United States as a proxy for the transmission of shocks through the economy and identify node positions (firms) whose connectedness provides a signal for economic growth. The nowcasting exercise, with both the in-sample and the out-of-sample consistent feature selection, highlights which firms are contemporaneously exposed to aggregate downturns and provides a more complete narrative than is usually provided by more aggregate data. The two-state model for predicting periods of negative growth can remarkably well predict future states by using information derived from the node-positions of manufacturing, transportation and financial (particularly insurance) firms. The three-states model, which identifies high, low and negative growth, successfully predicts economic regimes by making use of information from the financial, insurance, and retail sectors.

- Abstract
- This article first stresses the importance for a central bank of having a reliable quantitative framework for obtaining a real-time assessment of developments in economic activity in the near term and discusses associated challenges. Second, it presents the framework for short-term forecasting of euro area real GDP growth used at the ECB. The article evaluates the forecast performance of the framework, also comparing it with the Eurosystem/ECB staff macroeconomic projections. It also illustrates how the framework is used to i) analyse the role that data surprises play in the revisions to the outlook and ii) assess risks to the projections. It concludes by pointing out directions for future work.

- Abstract
- We model economic policy uncertainty (EPU) in the four largest euro area countries by applying machine learning techniques to news articles. The unsupervised machine learning algorithm used makes it possible to retrieve the individual components of overall EPU endogenously for a wide range of languages. The uncertainty indices computed from January 2000 to May 2019 capture episodes of regulatory change, trade tensions and financial stress. In an evaluation exercise, we use a structural vector autoregression model to study the relationship between different sources of uncertainty and investment in machinery and equipment as a proxy for business investment. We document strong heterogeneity and asymmetries in the relationship between investment and uncertainty across and within countries. For example, while investment in France, Italy and Spain reacts strongly to political uncertainty shocks, in Germany investment is more sensitive to trade uncertainty shocks.

- Abstract
- This box presents a model-based economic policy uncertainty (EPU) index for the euro area by applying machine learning techniques to news articles from January 2000 to May 2019. The machine learning algorithm retrieves components of overall EPU, such as trade, fiscal, monetary or domestic regulations, for a wide range of languages. Recently, a steady and pronounced increase in the euro area EPU index has been observed, driven mainly by trade, domestic regulation and fiscal policy uncertainties.

- 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 box reviews the characteristics of intangible assets and looks at a number of implications of their increasing importance. It finds that investment in intangible assets has increased in importance in the euro area, both in absolute terms and relative to tangible assets. Investment in intangibles enables productivity gains and can explain part of the gap between firms' investment in tangible assets and Tobin's Q. At the same time, the specific nature of intangible assets poses challenges as regards the measurement of activity, profits and capital stock, as well as making it less easy to use those assets as collateral.

- Abstract
- The degree of business cycle synchronisation, both across the euro area countries as well as between the euro area and the rest of the world, is a pertinent research question. Regarding the euro area, the endogenous optimal currency area (OCA) hypothesis suggests that the degree of business cycle synchronisation among the participating countries should increase over time as a result of deepening financial and trade integration. Individual countries should thus become less exposed to idiosyncratic shocks, facilitating the effectiveness of the single monetary policy. Against this background, this box presents and analyses several measures of business cycle synchronisation both within the euro area as well as from a global perspective.

- Abstract
- Growth in the consumption of durable goods has been very strong in recent years. During the financial crisis, durable goods consumption contracted sharply, although the car scrappage schemes in several euro area countries provided some relief by encouraging purchases of new cars (e.g. in 2009). Since 2013, durable goods consumption has again grown vigorously, pushing up growth in overall consumption. The recovery observed in real disposable incomes and the easing of financing conditions have both boosted households’ appetite for durable goods, particularly in those euro area countries that were more affected by the financial crisis.

- Abstract
- Although monetary union created the conditions for improving economic and financial integration in the euro area, in the context of the financial and sovereign crises, it has also been accompanied by the emergence of severe imbalances in savings and investment, credit and housing booms in some countries and the allocation of resources towards less productive sectors. The global financial crisis and the euro area sovereign debt crisis then led to major and abrupt adjustments as the risks posed by the large imbalances materialised. Although the institutional shortcomings in the EU that permitted the emergence of imbalances have been largely addressed since 2008, the adjustment process is not yet complete. From a macroeconomic perspective, the imbalances in the external accounts have led to the accumulation of high levels of external liabilities that need to be reduced, which, in turn, is weakening investment and therefore weighing on growth prospects and growth potential. From a macroprudential perspective, the lingering imbalances have added to systemic risk and rendered the euro area more vulnerable to risks. This Occasional Paper analyses the dynamic patterns in macroeconomic imbalances primarily from the former perspective, addressing in particular the connections between macroeconomic and sectoral adjustments of imbalances and the challenges for economic growth and performance over a longer horizon.
