Production Technology, Market Power, and the Decline of the Labor Share
Description: The labor share has been declining in the United States, and especially so in manufacturing. This paper investigates the role of capital accumulation and market power in explaining this decline. I first estimate the production function of 21 manufacturing sectors along time series and including time-varying markups. The elasticities of substitution for most sectors are estimated below one, implying that capital deepening cannot explain the labor share decline. I then track the long-run evolution of the labor share using the estimated production technology parameters. I decompose aggregate labor share changes into sector re-weights, capital-labor substitution, and market power effects. I find that the increase in market power, as reported in recent studies, can account for, at least, 76 percent of the labor share decline in manufacturing. Absent the rise in market power, the labor share would have remained constant in the second half of the 20th century.

The 2020-2022 Inflation Surge Across Europe: A Phillips-Curve-Based Dissection
Description: In 2021-22, inflation in Europe soared to multidecade highs, consistently exceeding policymakers’ forecasts and surprising with its wide cross-country dispersion. This paper analyzes the key drivers of the inflation surge in Europe and its variation across countries. The analysis highlights significant differences in Phillips curve parameters across Europe’s economies. Inflation is more sensitive to domestic slack and external price pressures in emerging European economies compared to their advanced counterparts, which contributed to a greater passthrough of global commodity price shocks into domestic prices, and, consequently, to larger increases in inflation rates. Across Europe, inflation also appears to have become increasingly backward looking and more sensitive to commodity price shocks since the onset of the COVID-19 pandemic. This finding helps explain why conventional (Phillips curve) inflation models consistently underpredicted the 2021-2022 inflation surge, although it remains too early to conclude there has been a structural break in the inflation process.

Estimating Digital Infrastructure Investment Needs to Achieve Universal Broadband
Description: We develop a detailed model to evaluate the necessary investment requirements to achieve affordable universal broadband. The results indicate that approximately $418 billion needs to be mobilized to connect all unconnected citizens globally (targeting 40-50 GB/Month per user with 95 percent reliability). The bulk of additional investment is for emerging market economies (73 percent) and low-income developing countries (24 percent). We also find that if the data consumption level is lowered to 10-20 GB/Month per user, the total cost decreases by up to about half, whereas raising data consumption to 80-100 GB/Month per user leads to a cost increase of roughly 90 percent relative to the baseline. Moreover, a 40 percent cost decrease occurs when varying the peak hour quality of service level from the baseline 95 percent reliability, to only 50 percent reliability. To conclude, broadband policy assessments should be explicit about the quantity of data and the reliability of service provided to users. Failure to do so will lead to inaccurate estimates and, ultimately, to poor broadband policy decisions.

What Policy Combinations Worked? The Effect of Policy Packages on Bank Lending during COVID-19
Description: This paper analyzes the impact of fiscal, monetary, and prudential policies during the COVID-19 pandemic on bank lending across a broad sample of countries. We combine a comprehensive announcementlevel dataset of policy actions with bank and firm-level information to analyze the effectiveness of different types of policies. We document that different types of policies were introduced together and hence accounting for policy combinations, or packages, is crucial. Lending grew faster at banks in countries that announced packages combining fiscal, monetary, and prudential measures relative to those that relied on some, but not all, policy dimensions. Within packages including all three types of policy measures, banks in countries with more and larger measures saw faster loan growth. The impact was larger among more constrained banks with low equity levels. Large packages combining fiscal, monetary and prudential policies also increased liquidity for bank dependent firms, but did not disproportionately benefit unviable firms.

Restructuring Domestic Sovereign Debt: An Analytical Illustration
Description: Sovereign domestic debt restructurings have become more common in recent years and touched upon a growing share of total public debt. This paper offers a simple framework for policymakers to think about the decision whether to restructure domestic sovereign debt as part of an effort to reduce overall public indebtedness. It also highlights a rather wide range of technical, legal, and operational issues a sovereign may face while restructuring domestic debt. As expected, factors such as debt reduction required to achieve sustainability, fiscal savings from a restructuring, and economic costs of a restructuring are key inputs into the decision making regarding a restructuring, but so are factors such as the composition of debt, financial stability costs, and crisis preparedness, all of which are discussed in the paper.

How to Mitigate the Impact of Economic Downturns on Labor Markets: Evidence from Nicaragua
Description: This paper studies the drivers of the labor market performance in Nicaragua with a particular focus on informality, to identify vulnerable groups during economic downturns; and estimates the speed of adjustment of employment to shocks. The paper compares this experience with the ones in other CAPDR countries (Costa Rica, Dominican Republic, El Salvador, Guatemala, Honduras, and Panama). Our findings are that while the high countercyclical informality in Nicaragua has been the active margin of adjustment during economic downturns mitigating unemployment, the trade-off has been a lower speed of adjustment to shocks hampering the country’s ability to revert to its potential. Policy recommendations relate to mitigating the impact of downturns on employment in Nicaragua, easing adjustments and inequalities in the labor market to hasten the employment recovery and thus, support growth.

Good Will Hunting: Do Disasters Make Us More Charitable?
Description: Humans are usually compassionate, caring and empathetic toward others, but are we really hardwired for altruism when a disaster hits? There is evidence that people exposed to natural disasters tend to behave more philanthropically, but most studies rely on small-scale surveys and experimental data. For that reason, this paper contributes to the literature by investigating whether the COVID-19 pandemic has altered prosocial tendencies and charitable donations, using a novel daily dataset of debit and credit card transactions. I conduct a real-time analysis of actual charitable donations in three European countries and find that the COVID-19 pandemic and government interventions have no significant effect on how much people contribute to charities as a share of total spending. A higher preference for precautionary savings in the midst of the pandemic appears to outweigh altruistic behavior, while government welfare programs crowds out private charitable donations.

How Costly Will Reining in Inflation Be? It Depends on How Rational We Are
Description: We document that past highly inflationary episodes are often characterized by a steeper inflationslack relationship. We show that model-generated data from a standard small Dynamic Stochastic General Equilibrium (DSGE) model can replicate this empirical finding when estimated with different expectation formation processes. When inflation becomes de-anchored and expectations drift, we can observe high inflation even with a mildly positive output gap in response to cost-push shocks. The results imply that we should not use an unconditioned (not controlling for expectations change) Phillips curve estimated in normal times to predict the cost of reining in inflation. Our optimal policy exercises prescribe early monetary policy tightening and then easing in the context of positive output gaps and inflation far above the central bank target.

Fintech Payments in Public Financial Management: Benefits and Risks
Description: Fintech payments leverage large digital platforms to fill gaps in the traditional payment system. They have made great strides in increasing access to payment services in several countries around the globe. At the same time, like any innovation, the new payment models are exposed to risks in their operating environment. We review the main fintech payment models (mobile money, internet-based fintech payment, and digital money) and discuss operational and financial risks as well as challenges they face. We then explore how public financial management (PFM), especially treasury payments and non-tax revenue collections, could benefit from fintech payments by providing examples of early fintech applications in different countries and discuss the challenges of integrating them into the public sector. The use of fintech in public finance could bring various benefits—including strengthening fiscal transparency, improving budget planning and execution, and upgrading cash management—if public sector institutional and technological capacities are strengthened and risks are adequately mitigated.

Gold as International Reserves: A Barbarous Relic No More?
Description: After moving slowly downward for the better part of four decades, central bank gold holdings have risen since the Global Financial Crisis. We identify 14 “active diversifiers,” defined as countries that purchased gold and raised its share in total reserves by at least 5 percentage points over the last two decades. In contrast to the diversification of foreign currency reserves, which has been undertaken by advanced and developing country central banks alike, active diversifiers into gold are exclusively emerging markets. We document two sets of factors contributing to this trend. First, gold appeals to central bank reserve managers as a safe haven in periods of economic, financial and geopolitical volatility, when the return on alternative financial assets is low. Second, the imposition of financial sanctions by the United States, United Kingdom, European Union and Japan, the main reserve-issuing economies, is associated with an increase in the share of central bank reserves held in the form of gold. There is some evidence that multilateral sanctions imposed by these, and other countries have a larger impact than unilateral sanctions on the share of reserves held in gold, since the latter leave scope for shifting reserves into the currencies of other non-sanctioning countries.
