South Africa: The Financial Sector-Sovereign Nexus
Description: Globally, financial institutions have increased their holdings of domestic sovereign debt, tightening the linkage between the health of the financial system and the level of sovereign debt, or the “financial sector-sovereign nexus,” during the ongoing COVID-19 pandemic. In South Africa, the nexus is still relatively moderate, albeit rising, and the increased focus of the Prudential Authority on the associated risks provide reassurance. Options to mitigate such risks through the use of regulatory measures can be explored. However, absent the necessary fiscal consolidation and structural reforms, risks from the nexus to both the financial system and the sovereign will increase.

The Nexus Between Public Enterprise Governance, Financial Performance, and Macroeconomic Vulnerabilities: An Application to Moldova
Description: Strong governance frameworks for public enterprises have long been an anchor of stability and efficiency underpinning their financial operations and performance. Cross-country experiences with the adoption of robust legal, regulatory and institutional arrangements—in line with international best practices— proved critical in reducing well-known risks and vulnerabilities from such companies, clarifying the role of the state, improving the management of state assets, and ensuring a level playing field for the private sector to prosper. Moldova’s large public enterprise sector of over 900 companies faces elevated risks that amplify fiscal and macroeconomic vulnerabilities and undermine market competition, productivity, and private investment. Moldova stands to greatly benefit from strengthening its public corporate governance regime to put its public enterprises on a stronger footing, address vulnerabilities, and improve market structure.

Patterns and Drivers of Health Spending Efficiency
Description: Demands for ramping up health expenditures are at an all-time high. Countries’ needs for additional health resources include responding to the COVID-19 pandemic, closing gaps in achieving the Sustainable Development Goal in health in most emerging and developing countries, and serving an ageing population in advanced economies. Facing limited fiscal space for raising health spending focuses policymakers’ attention on ensuring that resources are used efficiently. How sizable are the potential gains—in terms of freeing up resources and delivering better health outcomes—from improving health spending efficiency? How has efficiency evolved over the past decade? What can policymakers do to boost it? This paper estimates health spending efficiency across countries using bias-corrected data envelopment analysis and finds sizable differences in efficiency across countries, in particular among emerging and developing countries compared to advanced economies. The examination of the evolution of efficiency reveals that important efficiency gains have been made in the majority of countries. The paper also explores some of the key drivers of efficiency and finds that lower income inequality, less corruption, and health interventions oriented at expanding population access to basic health services are associated with greater efficiency.

Financial Concerns and the Marginal Propensity to Consume in COVID Times: Evidence from UK Survey Data
Description: We study how household concerns about their future financial situation may affect the marginal propensity to consume (MPC) during the COVID-19 pandemic. We use a representative survey of UK households to compute the MPC from a hypothetical transfer of £500. We find that household expectations play a key role in determining differences in MPCs across households: households concerned about not being able to make ends meet have a 20% higher MPC than other households. Our findings suggest that policies targeted to vulnerable and financially distressed households may prove more effective in stimulating demand than providing stimulus payments to all households.

Has Chinese Aid Benefited Recipient Countries? Evidence from a Meta-Regression Analysis
Description: This paper employs a meta-regression analysis of 473 estimates from 15 studies to take stock of the empirical literature on Chinese aid effectiveness. After accommodating publication selection bias, we find that, on average, Beijing’s foreign assistance has had a positive impact on economic and social outcomes in recipient countries but an opposite effect on governance, albeit negligible in size. We also show that (i) studies that fail to uncover statistically significant effects are less likely to be submitted to journals, or accepted for publication; and (ii) results are not driven by authors’ institutional affiliation. Differences in study characteristics such as the type of development outcome considered, how the Chinese aid variable is measured, the geographic region under study, and publication outlet explain the heterogeneity among Chinese aid effectiveness estimates reported in the literature.

Building Statistical Capacity in Fragile and Conflict-Affected States
Description: Based on internal data, this paper finds that the capacity development program of the IMF’s Statistics Department has prioritized technical assistance and training to fragile and conflict-affected states. These interventions have yielded only slightly weaker results in fragile states than in other states. However, capacity development is constantly needed to make up for the dissipation of progress resulting from insufficient resources that fragile and conflict-affected states allocate to the statistical function, inadequate inter-agency coordination, and the pervasive impact of shocks exogenous to the statistical system. Greater coordination with other capacity development providers and within the IMF can help partially overcome low absorptive capacity in fragile states. Statistical capacity development is more effective when it is tailored to countries’ level of fragility.

Consumption Effects of Mortgage Payment Holidays: Evidence during the COVID-19 Pandemic
Description: We use UK transaction-level data during the Covid-19 pandemic to study whether mortgage payment holidays (PH) can act as a mechanism for smoothing household consumption following negative aggregate shocks. Our results suggest that mortgage PH were accessed by both households with pre-existing financial vulnerabilities and by those with stronger balance sheets, including buy-to-let investors. We also find that the temporary liquidity relief provided by PH allowed liquidity-constrained households to maintain higher annual consumption growth compared to those non-eligible for the policy. Finally, we find that mortgage PH led to higher saving rates for more financially-stable households.

Fix vs. Float: Evaluating the Transition to a Sustainable Equilibrium in Bolivia
Description: Bolivia has achieved noteworthy success over the past 15 years in raising incomes, reducing poverty, and maintaining macroeconomic stability by deploying commodity revenues to finance transfers, public investment, and state-led development, using an exchange rate peg as a policy anchor. However, with the end of the commodity boom in 2014, fiscal deficits have grown and reserves have fallen. One route to restoring long-run sustainability would be to combine fiscal consolidation with a switch to a floating exchange rate. However, a preference for maintaining the peg could be accommodated with adjustments elsewhere in the policy framework. Employing a detailed dynamic stochastic general equilibrium model of the Bolivian economy, this study assesses the long-run sustainability and relative benefits of alternative policy combinations, and calculates optimal adjustment paths for the transition from the present situation to the steady state. It concludes that continued adherence to a fixed-rate regime, while not optimal, is feasible, if supported by a larger fiscal effort.

Are Low-Skill Women Being Left Behind? Labor Market Evidence from the UK
Description: Labor markets in the UK have been characterized by markedly widening wage inequality for lowskill (non-college) women, a trend that predates the pandemic. We examine the contribution of job polarization to this trend by estimating age, period, and cohort effects for the likelihood of employment in different occupations and the wages earned therein over 2001-2019. For recent generations of women, cohort effects indicate a higher likelihood of employment in low-paying manual jobs relative to high-paying abstract jobs. However, cohort effects also underpin falling wages for post-1980 cohorts across all occupations. We find that falling returns to labor rather than job polarization has been a key driver of rising inter-age wage inequality among low-skill females. Wage-level cohort effects underpin a nearly 10 percent fall in expected lifetime earnings for low-skill women born in 1990 relative to those born in 1970.

Sub-Saharan Africa: Building Resilience to Climate-Related Disasters
Description: This paper assesses the impact of climate-related disasters on medium-term growth and analyzes key structural areas that could substantially improve disaster-resilience. Results show that (i) climaterelated disasters have a significant negative impact on medium-term growth, especially for sub-Saharan Africa; and (ii) a disaster’s intensity matters much more than its frequency, given the non-linear cumulative effects of disasters. In sub-Saharan Africa, electrification (facilitating irrigation) is found to be most effective for reducing damage from droughts while improved health care and education outcomes are critical for raising resilience to floods and storms. Better access to finance, telecommunications, and use of machines in agriculture also have a significant impact.
