Estimation and Determinants of Cost Efficiency: Evidence from Central Bank Operational Expenses
Description: The finances of central banks is a topic of renewed interest: many central banks are posting significant losses due to the cost of monetary policy, over which central banks have no control. Conversely, operational expenses, over which the central banks have more control, is a subject of less attention. We use public income statement data from central banks to calculate a score for operational expense efficiency based on a stochastic frontier analysis. In addition, we offer potential explanations for the observed variations in efficiency levels across central banks. Our analysis reveals significant heterogeneity across countries and income groups. Central banks with a single objective demonstrate higher efficiency compared with those with multiple objectives. Regarding the output of price stability, central banks in low-income developing countries exhibit lower efficiency compared with central banks in emerging markets and advanced economies. Factors such as central bank independence, the depth of the financial system, and the degree of openness play a role in influencing efficiency levels. Our findings underscore the significance of well-defined objectives, the operating environment, and concentration on core activities in reducing inefficiency.

Cryptocarbon: How Much Is the Corrective Tax?
Description: With increasing awareness of past environmental damage from crypto mining, questions arise as to how persistent the problem will be in the future and how taxation can help in addressing this negative externality. We estimate that the global demand for electricity by crypto miners reached that of Australia or Spain, resulting in 0.33% of global CO2 emissions in 2022. Projections suggest sustained future electricity demand and indicate further increases in CO2 emissions if crypto prices significantly increase and the energy efficiency of mining hardware is low. To address global warming, we estimate the corrective excise on the electricity used by crypto miners to be USD 0.045 per kWh, on average. Considering also air pollution costs raises the tax to USD 0.087 per kWh. Country-specific estimates vary depending on their electricity sources.

The Financial Cost of Using Special Drawing Rights: Implications of Higher Interest Rates
Description: Since the August 2021 SDR allocation, the SDR interest rate has risen about 390 basis points through end-June 2023. This paper analyzes the impact of higher SDR interest rates on IMF members with negative net SDR Department positions. To do so, it constructs SDR forward curves at different points in time, from which the expected cost of servicing SDR obligations can be compared. Results show that the expected path of the SDR interest rate has shifted significantly upward since the 2021 allocation. Expected costs of charges (interest) in net present value terms are estimated to have more than tripled, while the grant element of SDRs has fallen to just below the IMF’s concessionality threshold. Despite this increase in cost, IMF members’ capacity to service SDR obligations remains generally adequate in both baseline and stress scenarios, though a few countries will need to carefully manage the rise in interest costs. Decisions to convert SDRs should consider interest rate risks, among other country-specific factors.

Dining and Wining During the Pandemic? A Quasi-Experiment on Tax Cuts and Consumer Spending in Lithuania
Description: Could temporary tax cuts stimulate consumer spending? Sector-specific measures to the COVID-19 pandemic provides a quasi-experimental variation in consumption patterns to infer a causal effect of tax policy changes. Using a novel dataset of daily debit and credit card transactions, this paper investigates the effectiveness of Lithuania’s decision to cut the standard value-added tax (VAT) rate from 21 percent to 9 percent on restaurants and catering services during the pandemic in a difference-in-differences regression framework. I obtain robust evidence that the VAT reduction has had no statistically significant impact on consumer spending on restaurants and catering services, while other policy interventions such as mobility restrictions and vaccination have more pronounced effects. These results have important policy implications in terms of the expected stimulative effect of sector-specific VAT reductions and the effective design of fiscal policy interventions to counter the impact of pandemics during which mobility is highly constrained.

Debtor (Non-)Participation in Sovereign Debt Relief: A Real Option Approach
Description: Developing countries have recently proved reluctant to participate in sovereign debt moratoria and debt relief initiatives. We argue that debtors' (non-)participation decisions can be understood through the lens of real options. Eligible countries compare the net benefits of participating in a debt relief initiative now with the value of waiting to potentially execute their participation option later, when they may have more information on the benefits and costs. We corroborate the real option framing with anecdotal evidence and through a survival analysis that exploits cross-country and time variation in the requests to participate in the Debt Service Suspension Initiative (DSSI), which provided temporary debt moratoria during the COVID-19 pandemic. Structured along the policy levers suggested by the real option framework, we discuss a number of ways in which participation in debt relief initiatives can be made more attractive to debtor countries.

The Role of Structural Fiscal Policy on Female Labor Force Participation in OECD Countries
Description: This paper examines the role of structural fiscal policies to promote female labor force participation and reduce gender gaps in labor markets in 26 OECD countries from 2000 to 2019. As both female labor force participation and many explanatory/control variables clearly exhibit non-stationarity (potentially leading to spurious regression results), we employ a panel vector error-correction model, in contrast with most previous empirical studies on this matter. Our analyses confirm statistically significant positive impacts of government spending on (1) early childcare and education, (2) active labor market programs, and (3) unemployment benefits, all of which would help encourage women to enter the labor force, while (4) an increase in relative tax rate on second earner could have negative impact on female labor force participation.

Spillovers from Russia to Neighboring Countries: Transmission Channels and Policy Options
Description: This paper studies how output fluctuations in Russia are transmitted internationally. Using vector autoregression (VAR) and dynamic panel models, the paper finds that Russia’s output fluctuations are an important driver of output fluctuations of countries in the region, especially for oil importers, and are transmitted increasingly via trade and market confidence channels. The magnitude of cross-border spillovers is larger for countries with relatively high bilateral trade concentration, low export diversification, and weak external buffers. The paper also finds evidence that stronger public institutional quality- especially in the fiscal area- may help insulate countries from volatility in the Russian sovereign debt market.

Cross-Border Risks of a Global Economy in Mid-Transition
Description: This paper analyzes the cross-border risks that could result from a decarbonization of the world economy. We develop a typology of cross-border risks and their respective channels. Our qualitative and quantitative scenario analysis suggests that the mid-transition – a period during which fossil-fuel and low-carbon energy systems co-exist and transform at a rapid pace – could have profound stability and resilience implications for global trade and the international financial system.

Global Economic Impacts of Physical Climate Risks
Description: This paper evaluates the global economic consequences of physical climate risks under two Shared Socioeconomic Pathways (SSP 1-2.6 and SSP 2-4.5) using firm-level evidence. Firstly, we estimate the historical sectoral productivity changes from chronic climate risks (gradual changes in temperature and precipitation) and extreme climate conditions (representative of heatwaves, coldwaves, droughts, and floods). Secondly, we produce forward-looking sectoral productivity changes for a global multisectoral sample of firms. For floods, these estimates account for the persistent productivity changes from the damage to firms’ physical capital. Thirdly, we assess the macroeconomic impact of these shocks within the global, multisectoral, intertemporal general equilibrium model: G-Cubed. The results indicate that, in the absence of additional adaptation relative to that already achieved by 2020, all the economies would experience substantial losses under the two climate scenarios and the losses would increase with global warming. The results can be useful for policymakers and practitioners interested in conducting climate risk analysis.

Informality, Labor Market Dynamics, and Business Cycles in North Africa
Description: Employment informality is widespread across North Africa. This paper aims to shed light on the role played by the informal sector in labor market adjustments over the business cycle. It finds that the response of labor markets to output fluctuations is more muted in countries with higher informality levels, like the North African economies. The analysis also confirms that informal employment is countercyclical and acts as a buffer during economic downturns in countries with relatively higher informality. However, contrary to what took place in past recessions, informal employment contracted sharply during the 2020 pandemic recession in high informality economies, suggesting that it did not play its traditional countercyclical role. By contrast, employment informality tends to fall modestly or increase during economic upturns, including the post-pandemic recovery. This finding presages the persistence of a large informal sector in the post-covid era in medium- and high-informality countries.
