Evaluating Spatial Underperformance : A Spatial Computable General Equilibrium Model Applied to Ho Chi Minh City
Thu Duc, a rapidly urbanizing area of Ho Chi Minh City, is well located and heavily invested in policy ambition, yet its output and density remain far below what its position in the metropolitan economy would support. Much of it is also flood exposed. This paper asks how much of that shortfall flood risk explains, and what coordinated investment could recover. A Spatial Computable General Equilibrium model of the Greater Ho Chi Minh City Metropolitan Area, covering 116 cells across Ho Chi Minh City and neighboring provinces, evaluates interventions to 2040. The model endogenizes firm location, household residence and commuting, land use intensity, and agglomeration externalities, recovering ..
The World Bank > Documents & ReportsSafe Spaces to Digital Spaces : Short-Term Impacts of Life Skills and Digital Literacy Training for Adolescent Girls in Nigeria
Educational attainment among adolescent girls in Nigeria remains low, particularly in the northern states where early marriage and limited schooling constrain women's economic opportunities. This study evaluates whether school-based life skills training delivered in safe spaces within senior secondary schools, alone or combined with digital literacy training, can improve educational, health, and economic outcomes for adolescent girls in northern Nigeria. Twelve months post-intervention, girls in treated schools show modest improvements in curriculum-related knowledge, with no effects on school retention or socio-emotional skills. Adding digital literacy training improved digital skills in th..

Childcare burdens limit productivity among women in the informal sector, but little is known about the optimal design of childcare support. The study randomizes 883 women market vendors in Kampala, Uganda to receive free workplace- or community-based childcare. Free childcare redistributes caregiving away from household members, raises women’s hourly earnings, and improves child development and women’s well-being. Community centers achieve higher utilization and larger gains in development and well-being, while workplace centers generate larger economic impacts. Both models have a high marginal value of public funds. Community centers currently dominate, but workplace-based centers could..

While the literature on the minimum wage is largely retrospective, analyzing impacts of past policy changes, this paper is uniquely forward-looking, forecasting how a proposed reform in Ukraine would affect future employment, earnings, and social contributions. The analysis simulates these effects by mimicking a proposal that would set a minimum wage floor equal to 40 percent of the previous year’s average wage once martial law is over and increasing the minimum wage by two percentage points annually until reaching 50 percent of the previous year’s average wage. The analysis draws on a 10 percent random sample of 2023 worker-level data from the Pension Fund of Ukraine, covering all jobs ..
The World Bank > Documents & ReportsPredicting Debt Distress in Low-Income Countries
This paper develops an empirical model to predict episodes of debt servicing difficulties (“debt distress”) in low-income countries, with three main contributions to the existing literature. First, it develops more refined measures of external debt distress episodes that allow timing the onset of distress episodes with increased precision. Second, it develops a systematic algorithm to comprehensively assess the out-of-sample predictive performance of more than 550,000 candidate binary prediction models using J-K-fold cross-validation. Third, it tests whether more sophisticated machine learning algorithms can outperform simple probit models. The paper finds that simple single-equation pro..
The World Bank > Documents & ReportsOpenness and Productivity Reform: Lessons for Middle-Income Economies from Thailand and other ASEAN
How can middle-income economies convert trade openness and productivity-enhancing reforms into higher real income and welfare? This paper develops a quantitative trade model with input-output linkages and labor market frictions to assess the impact of trade and productivity reforms on real income, wages, trade, and production. Thailand and ASEAN provide a useful case because the region spans economies with very different approaches to growth: some deeply embedded in Asian manufacturing value chains, others focused on commodities, export-led industrializers, and countries pursuing more selective integration. This variation allows assessing when openness yields large welfare gains, when produc..
The World Bank > Documents & ReportsNot Too Much, Not Too Little : A Goldilocks Approach to Sustainable, Universal Electricity Access in Sub-Saharan Africa
This paper proposes a replicable regulatory and financial framework to achieve universal electricity access as a core component of a just energy transition in Sub-Saharan Africa. It argues that universal access is feasible under realistic constraints when electrification planning, tariff regulation, and capital mobilization are designed as one coherent system rather than separate workstreams. The analysis rests on a computational, multi-period financial model that integrates individual interacting sub-models for every actor in the distribution segment. Versions of the same overall approach are applied to three countries, spanning different starting points and sector structures. Uganda provid..
The World Bank > Documents & ReportsWhat Does Venture Capital Actually Finance ? Scale and Structure around the World
Venture capital is widely viewed as financing knowledge-intensive, R&D-driven startups, but owing to data constraints, this view has been based largely on high-income economies. By taking a global perspective, this paper documents that what venture capital finances differs systematically across economies, varying with institutional and business conditions rather than following a single model. Using a new cross-country dataset that harmonizes firm-level venture capital records with equity issuance data for more than 150 economies, the data shows that VC markets differ across countries not only in scale but in kind. Outside high-income countries, rather than being concentrated in knowledge int..
The World Bank > Documents & ReportsUnderstanding the Impact of Multi-Nodal Urban Systems on Thailand's Urban Economies : Insights from a Dynamic Recursive Spatial General Equilibrium Model
Thailand's transition to high-income status is, at its core, an urban challenge. Bangkok generates nearly half of the national gross domestic product, yet its dominance is increasingly constrained by congestion, environmental stress, and diminishing returns to further concentration. Successive National Spatial Development Strategies have called for a more multi-nodal urban hierarchy, but the analytical basis for evaluating that ambition has remained thin. This paper builds and calibrates a Dynamic Recursive Spatial Quantitative General Equilibrium model for Thailand's urban system from 2025 to 2050, and uses it to evaluate three counterfactual policy portfolios that allocate the same aggrega..
The World Bank > Documents & ReportsGender Gaps in Pay and Advancement within Firms : Evidence from Ethiopia’s Financial Sector
Gender gaps in pay and leadership roles are well documented across labor markets. However, the literature on low- and middle-income countries is limited, and it remains unclear whether these gaps reflect sorting into lucrative, high-skill sectors or differential career progression within those sectors. This paper examines gender differences in compensation, advancement, and career-relevant mechanisms within such a high-skill sector, focusing on finance in Ethiopia and using evidence from the country’s largest commercial bank, the Commercial Bank of Ethiopia, which is estimated to account for roughly one-quarter of employment in the country’s finance sector. Using six years of administrat..

Eurostat > Statistical ReportsSix Years of High-Frequency Phone Surveys : Lessons from Sub-Saharan Africa
Phone surveys emerged as a critical data collection tool in low- and middle-income countries during the COVID-19 pandemic and have since become a permanent feature of the data landscape in many settings. This paper draws on the experience of the Living Standards Measurement Study High-Frequency Phone Surveys — one of the longest-running and largest longitudinal phone survey initiatives in low- and middle-income countries. The paper examines three methodological challenges central to the sustainable implementation of the surveys: individual-level data collection and respondent selection, attrition, and integration of phone and in-person surveys in mixed-mode data systems. The Living Standar..
The World Bank > Documents & ReportsHow Public Financial Management Shapes Education and Health Outcomes : A Configurational Perspective
This study examines how configurations of public financial management performance, sectoral spending, and governance context shape education and health outcomes across developing and middle-income economies. Using fuzzy set qualitative comparative analysis and Bayesian robustness checks, the analysis identifies multiple sufficient pathways linking budget execution credibility to primary education, secondary education, universal health coverage, and under five mortality outcomes. The findings confirm that public financial management conditions operate through conjunctural combinations rather than linear channels, their explanatory reach is stronger for intermediate than longer term outcomes, ..
The World Bank > Documents & ReportsHow to Build a Reader : Evidence from a Scalable Literacy Intervention in Ghana
Addressing the massive test score gaps between rich and poor countries will require programs that are both high-impact and scalable. This study uses the results of a randomized controlled trial in low-fee private schools in Ghana to study a program that meets both needs. The Tools for Foundational Learning Improvement program increased test scores by 0.5 standard deviation after just nine months of intervention. A machine learning method decomposes the effects by predicted test scores if the students did not receive the treatment, and the findings show that the gains were larger for weaker students. Moreover, the program’s impacts scale roughly linearly with time compared to a shorter-term..
The World Bank > Documents & ReportsSelection or More Capital ? Experimental Evidence on High-Growth Entrepreneurs in Kenya
Business plan competitions aim to identify and spur high-growth entrepreneurs. Two experiments were embedded into in a Kenyan competition to test how intensity of selection and of capital determine entrepreneurial outcomes. Applicants received a US$9,000 grant after a streamlined process or went through multiple selection stages and were randomly assigned US$9,000 or US$36,000. All grants initially generated jobs, but the impacts only persisted over three years under multi-stage selection. The larger grants did not yield greater long-term impacts than the multi-stage US$9,000 grant, suggesting diminishing returns to capital and limited lumpy investment opportunities. Selection, rather than g..
The World Bank > Documents & ReportsLabor Market Effects of Public Employment Guarantee
Public employment guarantee schemes, which channeled graduates into lifetime positions in the civil service and state-owned enterprises, were central to state-led industrialization across the postcolonial world, yet they have remained far less studied than temporary workfare programs. This paper provides the first causal estimates of their labor market effects, exploiting the Arab Republic of Egypt's archetypal public employment guarantee, which from the early 1960s guaranteed public sector jobs to secondary and university graduates without competitive examination. The paper measures district-level exposure by secondary school supply on the eve of the reform (1959/60) and links it to individ..
The World Bank > Documents & ReportsThe Long-Run Impacts of Protected Areas on Income, Birds, and Tourism in South Africa
Protected areas cover 17% of the world’s land surface, yet credible evidence on their long-run economic and ecological impacts remains scarce. This paper estimates the effects of South Africa’s protected areas on household income, bird biodiversity, and tourism consumer surplus. For the income and biodiversity analyses, it develops a machine-learning counterfactual approach that recovers the present-day impacts of protected areas created up to 100 years ago. Short-run impacts of newer protected areas are small and statistically insignificant, while older protected areas generate large gains. Prior research may have severely underestimated the benefits of protected areas by only estimatin..
The World Bank > Documents & ReportsConsequences of Growing Up Displaced : Evidence from Displaced Children in Colombia
This paper examines how forced displacement shapes child development beyond socioeconomic disadvantage. The paper uses original data on roughly 1,600 Venezuelan refugees, Colombian internally displaced individuals, and nondisplaced children in Medellín, Colombia. The analysis adapts rank-rank regressions from the intergenerational mobility literature to a forced displacement setting, ranking each child’s developmental outcomes against household wealth. The paper documents substantial gaps that persist after holding wealth and parental background fixed. It also shows that the cause of displacement shapes the nature of the gaps. Venezuelan refugees displaced by acute material deprivation fa..
The World Bank > Documents & ReportsCheap Energy Might Not Be Enough : A Trade Model of AI Compute Services
Can energy-rich developing countries convert cheap electricity into AI compute exports? This paper develops a capacity-constrained trade model of AI compute services with bilateral frictions in delivery, regulation, and trust. Calibrating the model across 85 countries shows that several developing economies can produce compute at low cost, but this advantage rarely becomes export competitiveness. Because hardware dominates unit costs and is globally priced, cross-country production costs differ by only 12–20 percent. Modest regulatory, financing, and trust frictions can therefore erase the gains from cheap power. The binding constraint is institutional credibility rather than electricity p..
The World Bank > Documents & ReportsRegularization and the Formation of Social Capital : Evidence from Forced Migrants in Colombia
This paper estimates the medium-run effects, 4.5 years after launch, of a regularization program that granted temporary legal status, freedom of movement, work authorization, and access to social programs to nearly half a million Venezuelan forced migrants in Colombia with no criminal record. Because the program was announced unexpectedly and applied retroactively to migrants who had registered in a census before a sharp eligibility cutoff, the paper identifies its effects using a fuzzy regression discontinuity design and a unique two-wave panel survey. The largest medium-run gains were in social capital. At the cutoff, eligible migrants scored 0.95 standard deviation higher than ineligible ..
The World Bank > Documents & ReportsStanley Fischer Memorial Lecture : Public Debt and Central Banks — The World Bank Group ABCDE Conference
This paper, based on the Stanley Fischer Memorial Lecture that the author delivered at the Annual Bank Conference on Development Economics (ABCDE) 2026, examines two structural impediments to broad-based economic development: dysfunctional central bank currency systems and inadequately resolved sovereign debt burdens. On currency, the paper argues that floating exchange rate regimes and multiple exchange rate systems—as practiced in countries such as Ethiopia, Nigeria, and Egypt—systematically transfer wealth from low-income wage earners to a narrow-privileged class, deepening poverty rather than alleviating it. Using Ethiopia as a central case study, the paper documents how successive d..
