Overcoming Data Sparsity: A Machine Learning Approach to Track the Real-Time Impact of COVID-19 in Sub-Saharan Africa
Description: The COVID-19 crisis has had a tremendous economic impact for all countries. Yet, assessing the full impact of the crisis has been frequently hampered by the delayed publication of official GDP statistics in several emerging market and developing economies. This paper outlines a machine-learning framework that helps track economic activity in real time for these economies. As illustrative examples, the framework is applied to selected sub-Saharan African economies. The framework is able to provide timely information on economic activity more swiftly than official statistics.

Advancing the Monetary Policy Toolkit through Outright Transfers
Description: This paper argues that in reserve currency issuing economies at the effective lower bound, outright transfers from the central bank to households are both more equitable and more effective in achieving monetary policy objectives than asset purchases or negative interest rates. It shows that concerns pertaining to central banks’ policy solvency and equity position can be addressed through a careful assessment of a central bank's loss absorbing capacity and, if need be, tiered reserve remuneration policies. It also spells out key differences to a debt or money financed fiscal stimulus, which are particularly pronounced in a currency union without a central fiscal capacity. The paper concludes by discussing broader institutional, political, and legal considerations.

Measuring Carbon Emissions of Foreign Direct Investment in Host Economies
Description: This paper presents estimates of the carbon emissions of FDI from capital formation funded by FDI and the production of foreign-controlled firms. The carbon intensity of capital formation financed by FDI has trended down, driven by reductions in the carbon intensity of electricity generation. Carbon emissions from the operations of foreign-controlled firms are greater than those from their capital formation. High emission intensities were accompanied by high export intensities in mining, transport, and manufacturing. Home country policies to incentivize firms to meet strict emissions standards in both their domestic and foreign operations could be important to reducing emissions globally.

Reported Social Unrest Index: March 2022 Update
Description: This paper updates the Reported Social Unrest Index of Barrett et al (2020), reviewing recent developments in social unrest worldwide since the start of the COVID-19 Pandemic. It shows that unrest was elevated during late 2019, coincident with widespread protests in Latin America. Unrest then fell markedly during the early stages of the pandemic as voluntary and involuntary social distancing struck. Social unrest has since returned but generally remains below levels seen in 2019.

Cross-Border Central Bank Digital Currencies, Bank Runs and Capital Flows Volatility
Description: Central banks around the world are increasingly exploring central bank digital currencies (CBDCs). This paper investigates the possible impacts of cross-border CBDCs on capital flows and financial stability in a simple open economy extension of a classical model of bank runs, augmented with the presence of a credible foreign central bank, which issues an account-based interest bearing CBDC available to nonresidents. The paper finds that the presence of a foreign CBDC which acts as an international safe asset may increase the risk of financial disintermediation in the domestic banking sector, which can be accompanied by higher and more volatile capital flows.

Fiscal Multipliers and Informality
Description: This paper investigates the role of informality in affecting the magnitude of the fiscal multiplier in a panel of 141 countries, using the local projections method. We find a strong negative relationship between the degree of informality and the size of the fiscal multiplier. This result holds irrespective of the levels of economic development and institutional quality and is robust to additional country characteristics such as trade, financial openness and exchange rate regime. In a two-sector new- Keynesian model, we rationalize this result by showing that fiscal shocks raise the relative price of official goods, shifting demand towards the informal sector. This reallocation effect increases with the level of informality, because a larger informal sector is associated with a stronger appreciation of relative prices in response to fiscal shocks. Thus, informality raises the size of the unofficial multiplier. A higher degree of non-separability between public and private goods also contributes to rationalize the lower multipliers in high-informality countries.

Trade and the COVID-19 Pandemic: Lessons from French Firms
Description: This paper uses granular customs data from France to investigate propagation of the COVID-19 shock along the supply chains in 2020. It quantifies the effect of the COVID-19 shock on trade adjustment and identifies mitigating and amplifying factors contributing to French firms’ heterogeneous adjustment paths. Early in the pandemic, firms mainly responded to global lockdowns and spread of the virus by reducing trade volumes (intensive margin) as opposed to exiting from import and export markets (ex-tensive margin). However, adjustment along the extensive margin played a more important role in trade with developing countries. It is shown that the impact of lockdowns was stronger for final consumer goods and the trade recovery was predominantly demand-driven. More automated, inventory-intensive, older, and medium-sized firms were more insulated from the shock, whereas firms’ reliance on air transportation for shipping goods amplified the shock. Trade bans and promotion measures implemented by governments in response to the pandemic had little impact on aggregate trade flows.

Fintech: Financial Inclusion or Exclusion?
Description: This paper examines the role of Fintech in financial inclusion. Using Global Findex data and emerging fintech indicators, we find that Fintech has a higher positive correlation with digital financial inclusion than traditional measures of financial inclusion. In the second stage of our empirical investigation, we examine the key factors that are correlated with the Fletcher School’s three digital divide – gender divide, class (rich-poor) divide and rural divide. The results indicate that greater use of fintech is significantly associated with a narrowing of the class divide and rural divide but there was no impact on the gender divide. These findings imply that Fintech alone may not be sufficient to close the gender gap in access to financial services. Fintech development may need to be complemented with targeted policy initiatives aimed at addressing the gender gap directly, and at changing attitudes and social norms across demographics.

Sovereign Debt Repatriation During Crises
Description: We use a new, comprehensive data set on the sovereign debt investor base to document three novel empirical facts: (i) sovereign debt is repatriated - that is, shifted from external private to domestic investors - prior to sovereign defaults; (ii) not all crises are equal: evidence for repatriation during banking and currency crises is more limited; and (iii) the nature of defaults matters: external investors do not leave during preemptive debt restructurings. We further show that repatriation appears to be prevalent when defaults happen in large markets with low capital controls. The data set we use is uniquely suited to analyzing investor base dynamics during rare crises due to its large cross-section and time series, covering 180 countries from 1989 to 2020.

High Performance Export Portfolio: Design Growth-Enhancing Export Structure with Machine Learning
Description: This paper studies the relationship between export structure and growth performance. We design an export recommendation system using a collaborative filtering algorithm based on countries' revealed comparative advantages. The system is used to produce export portfolio recommendations covering over 190 economies and over 30 years. We find that economies with their export structure more aligned with the recommended export structure achieve better growth performance, in terms of both higher GDP growth rate and lower growth volatility. These findings demonstrate that export structure matters for obtaining high and stable growth. Our recommendation system can serve as a practical tool for policymakers seeking actionable insights on their countries’ export potential and diversification strategies that may be complex and hard to quantify.
