An Evaluation of World Economic Outlook Growth Forecasts, 2004–17

Description: This paper examines the performance of World Economic Outlook (WEO) growth forecasts for 2004-17. Short-term real GDP growth forecasts over that period exhibit little bias, and their accuracy is broadly similar to those of Consensus Economics forecasts. By contrast, two- to five-year ahead WEO growth forecasts in 2004-17 tend to be upward biased, and in up to half of countries less accurate than a naïve forecast given by the average growth rate in the recent past. The analysis suggests that a more efficient use of available information on internal and external factors—such as the estimated output gap, projected terms of trade, and the growth forecasts of major trading partners—can improve the accuracy of some economies’ growth forecasts.

Intergenerational Social Mobility in Africa Since 1920

Description: The COVID-19 crisis has a severe impact on education and employment and exposed the many social inequities that make some populations more vulnerable to shocks. Despite a vast literature on social mobility in advanced economies, little is known about it in African countries, mainly due to data limitations. Using a large harmonized dataset of more than 72 million individuals, we fill this gap and examine socioeconomic status mobility across generations, measured by educational and occupational attainment. We uncover the substantial geographical variations in the degree of upward/downward educational and occupational mobility across and within African countries, and the gender and rural/urban divide. Additionally, we explore the determinants of social mobility in the African region. We find that social mobility on the continent could be partly explained by observable individual characteristics (gender, marital status, age, etc.), and that educational mobility is a driver of occupational mobility. Lastly, we show that the quality of institutions, the level of public spending on education, social protection coverage, natural resource endowments, and countries' fragility are strong predictors of social mobility in Africa.

Does IT Help? Information Technology in Banking and Entrepreneurship

Description: This paper analyzes the importance of information technology (IT) in banking for entrepreneurship. To guide our empirical analysis, we build a parsimonious model of bank screening and lending that predicts that IT in banking can spur entrepreneurship by making it easier for startups to borrow against collateral. We provide empirical evidence that job creation by young firms is stronger in US counties that are more exposed to ITintensive banks. Consistent with a strengthened collateral lending channel for IT banks, entrepreneurship increases more in IT-exposed counties when house prices rise. In line with the model's implications, IT in banking increases startup activity without diminishing startup quality and it also weakens the importance of geographical distance between borrowers and lenders. These results suggest that banks' IT adoption can increase dynamism and productivity.

The Impact of Environmental Policy on Innovation in Clean Technologies

Description: This paper studies the effect of climate change mitigating policies on innovation in clean energy technologies. Results suggest that the tightening of environmental policies since the early 1990s have made a statistically and economically significant contribution to the increase in clean innovation. These effects generally materialized quickly, within 2 to 3 years of the policy change, and were driven by individually significant marginal effects of both market-based policies – such as feed-in tariffs and trading schemes – as well as non-market policies, such as R&D subsidies or emission limits. Looking at electricity innovation in particular, the paper finds that the estimated effect on total innovation is positive on net, meaning that increased innovation in clean and grey technologies is not offset by a decrease in innovation in dirty technologies. From a policy point of view, the paper’s results call for strong policy efforts to decisively shift innovation towards clean technologies.

Global Corporate Stress Tests—Impact of the COVID-19 Pandemic and Policy Responses

Description: Corporate sector vulnerabilities have been a central policy topic since the outset of the COVID-19 pandemic. In this paper, we analyze some 17,000 publicly listed firms in a sample of 24 countries, and assess their ability to withstand shocks induced by the pandemic to their liquidity, viability and solvency. For this purpose, we develop novel multi-factor sensitivity analysis and dynamic scenario-based stress test techniques to assess the impact of shocks on firm’s ability to service their debt, and on their liquidity and solvency positions. Applying the October 2020 WEO baseline and adverse scenarios, we find that a large share of publicly-listed firms become vulnerable as a result of the pandemic shock and additional borrowing needs to overcome cash shortfalls are large, while firm behavioral responses and policies substantially help overcome the impact of the shock in the near term. Looking forward, while interest coverage ratios tend to improve over time after the initial shock as earnings recover in line with projected macroeconomic conditions, liquidity needs remain substantial in many firms across countries and across industries, while insolvencies rise over time in specific industries. To inform policy debates, we offer an approach to a triage between viable and unviable firms, and find that the needs for liquidity support of viable firms remain important beyond 2020, and that medium-term debt restructuring needs and liquidations of firms may be substantial in the medium-term.

Evolution of Bilateral Swap Lines

Description: This paper makes contributions to the study of bilateral swap lines (BSLs). First, this paper fills a BSL information gap by constructing a comprehensive database of BSLs based on publicly available information, including after the onset of the COVID-19 pandemic. Second, the paper provides the results of regression analysis exploring several empirical questions that were not covered in previous studies. The paper documents the evolution of BSLs into an important part of the Global Financial Safety Net (GFSN), with some helping to stabilize financial market during both the Global Financial Crisis (GFC) and the COVID-19 pandemic. Analysis suggests that countries on the recipient side of BSLs are more likely to sign and renew BSLs designed to alleviate balance of payments needs as their external position weakens. U.S. Federal Reserve BSLs appear to have been effective at stabilizing financial market conditions during the COVID-19 pandemic.

Unintended Consequences of U. S. Monetary Policy Shocks: Dutch Disease and Capital Flow Measures in Emerging Markets and Developing Economies

Description: Dutch disease is often referred as a situation in which large and sustained foreign currency inflows lead to a contraction of the tradable sector by giving rise to a real appreciation of the home currency. This paper documents that this syndrome has been witnessed by many emerging markets and developing economies (EMDEs) as a result of surges in capital inflows driven by accommodative U. S. monetary policy. In a sample of 25 EMDEs from 2000-17, U. S. monetary policy shocks coincided with episodes of currency appreciation and a contraction in tradable output in these economies. The paper also shows empirically that the use of capital flow measures (CFMs) has been a common policy response in several EMDEs to U.S. monetary policy shocks. Against this background, the paper presents a two sector small open economy augmented with a learning-by-doing (LBD) mechanism in the tradable sector to rationalize these empirical findings. A welfare analysis provides a rationale for the use of CFMs as a second-best policy when agents do not internalize the LBD externality of costly resource misallocation as a result of greater capital inflows. However, the adequate calibration of CFMs and the quantification of the LBD externality represent important implementation challenges.

Real Estate in the Netherlands: A Taxonomy of Risks and Policy Challenges

Description: Soaring real estate prices and valuations despite the economic downturn brought by the pandemic have focussed the attention of Dutch policymakers on potential macro-financial and socio-economic implications. In this context, our paper reviews the salient features of Dutch commercial and residential real estate markets with an eye to identify pertinent risks and challenges. While we find that the Dutch authorities have made considerable strides to strengthen real estate-related policies in recent years, some, and partly long-standing, issues remain, requiring additional efforts to bolster financial stability, address housing supply shortages and manage secular changes affecting property markets.

Mask Mandates Save Lives

Description: We quantify the effect of mask mandates in the United States. Our regression discontinuity design exploits county-level variation in COVID-19 cases, hospital admissions, and deaths across the border between states with and without mandates. We find a significant and substantial effect—mask mandates reduced new weekly COVID-19 cases, hospital admissions, and deaths by 55, 11 and 0.7 per 100,000 inhabitants on average. Crucially, we find that the effect of mask mandates depends on the attitudes toward mask wearing at the county level, with larger effects in counties more positively inclined towards mask wearing. Our results imply that mandates saved 87,000 lives through December 19, 2020, while a nationwide mandate could have saved 58,000 additional lives. These large effects suggest that mask mandates are a crucial tool to counter pandemics, particularly if accepted widely by the population. Our results are thus also relevant for countries who will not be able to immunize large swaths of their population in the short term.

What Shapes Current Account Adjustment During Recessions?

Description: This paper studies the dynamics of external accounts during 278 economic recession events in the past 60 years and sheds light on key factors that shape these patterns. Economic recessions trigger highly-persistent increases in the current account, driven by an initial, sharp decline in investment and fueled by medium term deleveraging, more so in advanced economies than in emerging markets. The strengthening of the current account is more pronounced when internal and external imbalances are present, and less when recessions are synchronized across countries. During severe natural disasters or epidemics, however, current accounts tend to weaken in the short term. Consistent with these findings, the COVID-19 shock, with comparatively moderate pre-existing imbalances yet high synchronization, had a muted effect on current account balances. The compositional changes, however, were unique and driven by unprecedented policy intervention, with record public dissaving more than offsetting exceptional private saving.
