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.

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.

Watch What They Do, Not What They Say: Estimating Regulatory Costs from Revealed Preferences
Description: We show that distortion in the size distribution of banks around regulatory thresholds can be used to identify costs of bank regulation. We build a structural model in which banks can strategically bunch their assets below regulatory thresholds to avoid regulations. The resulting distortion in the size distribution of banks reveals the magnitude of regulatory costs. Using U.S. bank data, we estimate the regulatory costs imposed by the Dodd-Frank Act. Although the estimated regulatory costs are substantial, they are significatnly lower than those in self-reported estimates by banks.

The Effect of Tariffs in Global Value Chains
Description: This paper empirically investigates the impact of tariffs when production is organized in global value chains. Using global input-output matrices, we construct four different tariff measures that capture the direct and indirect exposure to tariffs at different stages of the production chain for a broad set of countries and industries. Our results suggest that tariffs have significant effects on economic outcomes, including on countries and sectors not directly targeted. We find that tariffs higher up and further down in the value chain depress value added, employment, labor productivity and total factor productivity to varying degrees. We find no benefits for the sector that enjoys additional protection, yet there is some evidence of economic activity being diverted, i.e. positive effects on value added and employment from tariffs imposed on competitors. Our paper relates to recent innovations in theoretical gravity models and provides an empirical assessment of possible long-term effects of recent trade tensions.

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.

Determinants and Effects of Countries’ External Capital Structure: A Firm-Level Analysis
Description: In this paper, we investigate whether a firm’s composition of foreign liabilities matters for their resilience during economic turmoil and examine which characteristics determine a firm’s foreign capital structure. Using firm-level data, we corroborate previous findings from the (international) macroeconomic literature that the composition of foreign liabilities matters for a country’s susceptibility to external shocks. We find that firms with a positive equity share in their foreign liabilities were less affected by the global financial crisis and also less likely to default in the aftermath of the crisis. In addition, we show that larger, more open, and more productive firms tend to have a higher equity share in total foreign liabilities.
