Crypto, Corruption, and Capital Controls: Cross-Country Correlations
Description: Empirical investigation of the factors underlying the growing usage of crypto-assets is in its infancy, owing to data limitations. In this paper, we present a simple cross-country analysis drawing on recently released survey-based data. We explore the correlation of crypto-asset usage with indicators of corruption, capital controls, a history of high inflation, and other factors. We find that crypto-asset usage is significantly and positively associated with higher perception of corruption and more intensive capital controls. Notwithstanding the data limitations, the results support the case for regulating crypto-assets, including know-your-customer approaches, as opposed to taking a laissez-faire stance.

Supply Chains and Port Congestion Around the World
Description: Rising prices and reports of empty shelves in major economies have drawn attention to the functioning of supply chains that normally operate smoothly in the background. Among the issues, the long delays that port congestion may have caused in delivering goods to consumers and firms have been gathering increasing attention. We shed light on these issues leveraging a unique data set on maritime transport. Two main features emerge. First, at the world level, we find that shipping times jumped upwards as soon as the COVID crisis hit, and after a marked acceleration from end-2020, delays surpassed 1.5 days on average by December 2021 – or roughly a 25 percent increase in global travel times. The estimated additional days in transit for the average shipment in December 2021 can be compared to an ad-valorem tariff of 0.9 to 3.1 percent. The midpoint of this range is approximately equal, in absolute value, to the global applied tariff reduction achieved over the 14-year period from 2003 to 2017. Second, not all congestion appears related to increased demand. Many ports, especially since mid-2021, exhibit longer wait times despite handling less cargo than pre-pandemic. Infrastructure upgrading is therefore likely a necessary, but not sufficient condition for building resilience during a crisis where other factors (such as labor shortages) may also become binding.

The Stealth Erosion of Dollar Dominance: Active Diversifiers and the Rise of Nontraditional Reserve Currencies
Description: We document a decline in the dollar share of international reserves since the turn of the century. This decline reflects active portfolio diversification by central bank reserve managers; it is not a byproduct of changes in exchange rates and interest rates, of reserve accumulation by a small handful of central banks with large and distinctive balance sheets, or of changes in coverage of surveys of reserve composition. Strikingly, the decline in the dollar’s share has not been accompanied by an increase in the shares of the pound sterling, yen and euro, other long-standing reserve currencies and units that, along with the dollar, have historically comprised the IMF’s Special Drawing Rights. Rather, the shift out of dollars has been in two directions: a quarter into the Chinese renminbi, and three quarters into the currencies of smaller countries that have played a more limited role as reserve currencies. A characterization of the evolution of the international reserve system in the last 20 years is thus as ongoing movement away from the dollar, a recent if still modest rise in the role of the renminbi, and changes in market liquidity, relative returns and reserve management enhancing the attractions of nontraditional reserve currencies. These observations provide hints of how the international system may evolve going forward.

Digitalization and Tax Compliance Spillovers: Evidence from a VAT e-Invoicing Reform in Peru
Description: Our study uses administrative data on firm-to-firm transactions and quasi- experimental variation in the rollout of electronic invoicing reforms in Peru to study the diffusion of e-invoicing through firm networks and its effect on tax compliance. We find that voluntary e-invoicing adoption is higher amongst firms with partners who are mandated to adopt e-invoicing, implying positive technology adoption spillovers. Spillovers are stronger from downstream partners and from export-oriented firms. Firms are less likely to continue transacting with a partner who has been mandated into e-invoicing, with the effect only partially reversed if both firms adopt e-invoicing, suggesting that network segmentation may occur. Smaller firms who transact with partners mandated into e-invoicing report 11 percent more sales and pay 17 more VAT in the year that their partner is mandated to adopt e-invoicing, suggesting positive spillovers in tax compliance behavior for this subset of firms.

The Financial Performance and Macrofinancial Implications of Large State-Owned Enterprises in Sub-Saharan Africa
Description: Using a newly-compiled dataset of state-owned enterprises in Sub-Saharan Africa, we present aggregate information about profitability, liquidity and leverage. We find that 40 percent of the close to 300 surveyed SOEs are unprofitable, while larger firms also tend to be illiquid and overleveraged. In cross-sectional regressions we find that SOE debt stock sustainability is impacted by firms’ profitability and liquidity, while macroeconomic factors cannot be shown to matter, expect for some governance variables. Based on these findings and citing country examples, we also illustrate that weak SOE performance may have a macrofinancial impact affecting bank soundness through delinquent loan exposures.

Estimating the Employment and GDP Multiplier of Emergency Cash Transfers in Brazil
Description: We estimate the subnational employment and GDP multiplier of Brazil's 2020 federal cash transfers to vulnerable households. Using two-stage least squares regressions we estimate a formal employment multiplier and then apply an analytical transformation to recover an implied GDP multiplier in the range of 0.5-1.5. The lower bound of this range lies below most estimates in the literature, which may result from the exceptional constraints imposed by the pandemic on supply chains and consumption. Nevertheless, even using the lower end of our range implies that federal cash transfers played an important role in supporting employment and GDP.

Climate Change in Sub-Saharan Africa Fragile States: Evidence from Panel Estimations
Description: Fragile states in sub-Saharan Africa (SSA) face challenges to respond to the effects of climate shocks and rising temperatures. Fragility is linked to structural weaknesses, government failure, and lack of institutional basic functions. Against this setup, climate change could add to risks. A panel fixed effects model (1980 to 2019) found that the effect of a 1◦C rise in temperature decreases income per capita growth in fragile states in SSA by 1.8 percentage points. Panel quantile regression models that account for unobserved individual heterogeneity and distributional heterogeneity, corroborate that the effects of higher temperature on income per capita growth are negative while the impact of income per capita growth on carbon emissions growth is heterogeneous, indicating that higher income per capita growth could help reduce carbon emissions growth for high-emitter countries. These findings tend to support the hypothesis behind the Environmental Kuznets Curve and the energy consumption growth literature, which postulates that as income increases, emissions increase pari passu until a threshold level of income where emissions start to decline.

The Availability, Methodological Soundness, and Scope of Consumer Price Statistics in 2020
Description: This paper analyzes the availability, methodological soundness, and scope of Consumer Price statistics in IMF member and non-member countries in 2020. Consumer price statistics are instrumental in the development of monetary policy and in monitoring economic developments. They also often have administrative uses such as in determine wage increase or seting pension payments. This analysis examines the appropriateness of the current set of global consumer price statistics for current policy development and highlights regions where further development may be required. The analysis is based on the results of a new annual survey of CPI compilation practices in 207 economies as of the end of 2020. The survey was completed by statistical authorities between March 2021 and June 2021. In cases of non-response, IMF staff estimates were used. IMF Staff estimates were based on information taken from the IMF’s Dissemination Standards Bulletin Board (DSBB) and country websites to provide the status of consumer price index compilation practices. These data summarize the following key aspects; i) Production, publication and scope of the Consumer Price Index Program, ii) Data sources, iii) CPI compilation methods and iv) Concepts and classifications.

Nowcasting GDP - A Scalable Approach Using DFM, Machine Learning and Novel Data, Applied to European Economies
Description: This paper describes recent work to strengthen nowcasting capacity at the IMF’s European department. It motivates and compiles datasets of standard and nontraditional variables, such as Google search and air quality. It applies standard dynamic factor models (DFMs) and several machine learning (ML) algorithms to nowcast GDP growth across a heterogenous group of European economies during normal and crisis times. Most of our methods significantly outperform the AR(1) benchmark model. Our DFMs tend to perform better during normal times while many of the ML methods we used performed strongly at identifying turning points. Our approach is easily applicable to other countries, subject to data availability.

Strengthening the WAEMU Regional Fiscal Framework
Description: This paper assesses the adequacy and effectiveness of the WAEMU fiscal framework along three pillars that have proven to effectively support fiscal discipline in monetary unions—common fiscal rules (including adequacy of numerical ceilings as well as elements of design and enforcement), shared public financial management systems, and coordination mechanisms for decentralized fiscal policies. We undertake a calibration of regional debt and fiscal deficit ceilings taking into account different macroeconomic tradeoffs and risks and conclude that numerical ceilings that prevailed before the suspension of the fiscal rules remain adequate and strike the right balance between growth and fiscal sustainability. The paper also proposes reform options to strengthen the WAEMU regional fiscal surveillance framework, with a view to more effectively supporting fiscal discipline.
