Abstract
Using high-resolution administrative, census, and satellite data, this paper shows that South African cities are characterized by spatial mismatches between where people live and where jobs are located, relative to 20 global peers. Areas within 5 kilometers of commercial centers have 9,300 fewer residents per square kilometer than expected, which is 60 percent below the global median. Poor, dense neighborhoods are most affected. In Johannesburg, a 10-percentile increase in distance from the nearest business hub corresponds to a 3.7-percentile drop in asset wealth (a proxy of household wellbeing) and 4.9-percentile drop in employment. In Cape Town, the declines are 4.0 and 3.7 percentiles, respectively. Employment is 87 percent lower in the poorest decile than the richest in Johannesburg and 61 percent lower in Cape Town. These findings suggest that South Africa’s spatial organization of people and economic activity constrains agglomeration and reinforces inequality. This methodology provides a scalable and standardized data-driven framework to analyze spatial accessibility and agglomeration frictions in complex, data-constrained urban systems.

Publication Climate and Social Sustainability in Fragility, Conflict, and Violence Contexts(Washington, DC: World Bank, 2026-01-07)Climate change is widely recognized as a driver of violent conflict, but its broader social effects remain less understood. Ignoring these dimensions risks a vicious cycle where climate policies might undermine socially just adaptation. Evidence is still limited on how climate shocks influence political participation, trust, or migration. This paper helps fill that gap by examining links between climate change, conflict, and social sustainability, with a focus on inclusion, resilience, cohesion, and legitimacy. Using secondary data from 2019–24, the study applies simple correlation-based methods to test three hypotheses on the nature, severity, and composition of these associations. The analysis combines multiple climate impact measures, new conflict classifications, recent social sustainability frameworks, and controls for population and geography. The results reveal strong correlations—not causation—between climate events and contexts of fragility, conflict, and violence. Climate impacts are most pronounced in both national and subnational conflict settings. The study also finds robust links between fragility, conflict, and violence and low levels of social sustainability, reflecting its role as both a driver and consequence of conflict. Some dimensions—such as violent events and insecurity—appear weaker in areas most affected by climate shocks. Two of the hypotheses are supported, and one remains inconclusive.Publication The Macroeconomic Implications of Climate Change Impacts and Adaptation Options(Washington, DC: World Bank, 2025-05-29)Estimating the macroeconomic implications of climate change impacts and adaptation options is a topic of intense research. This paper presents a framework in the World Bank's macrostructural model to assess climate-related damages. This approach has been used in many Country Climate and Development Reports, a World Bank diagnostic that identifies priorities to ensure continued development in spite of climate change and climate policy objectives. The methodology captures a set of impact channels through which climate change affects the economy by (1) connecting a set of biophysical models to the macroeconomic model and (2) exploring a set of development and climate scenarios. The paper summarizes the results for five countries, highlighting the sources and magnitudes of their vulnerability --- with estimated gross domestic product losses in 2050 exceeding 10 percent of gross domestic product in some countries and scenarios, although only a small set of impact channels is included. The paper also presents estimates of the macroeconomic gains from sector-level adaptation interventions, considering their upfront costs and avoided climate impacts and finding significant net gross domestic product gains from adaptation opportunities identified in the Country Climate and Development Reports. Finally, the paper discusses the limits of current modeling approaches, and their complementarity with empirical approaches based on historical data series. The integrated modeling approach proposed in this paper can inform policymakers as they make proactive decisions on climate change adaptation and resilience.Publication Institutional Capacity for Policy Implementation: An Analytical Framework(Washington, DC: World Bank, 2026-01-07)State capacity is an important prerequisite for policy implementation, yet at the country level it is difficult to measure, assess, and reform. This paper proposes a focus on institutional capacity: the ability of public institutions to implement the specific policy mandates for which they are responsible. Based on a review of existing literature, the paper defines the different dimensions that compose institutional capacity and groups them into two cross-cutting categories: organizational dimensions (personnel, financial resources, information systems, and management practices) and governance dimensions (transparency, independence, and accountability). The paper proposes measures for organizational and governance dimensions using existing data, shows intra-institutional variation of these measures within countries, and discusses how new data could be collected for better measurement of these concepts. Finally, the paper illustrates how the framework can be used to diagnose the sources of common problems related to weak policy implementation.Publication Investment in Emerging and Developing Economies(Washington, DC: World Bank, 2026-01-07)The world faces a pressing challenge to meet key development objectives amid slowing growth and rising macroeconomic and geopolitical risks. With the number of job seekers rising rapidly, infrastructure shortfalls continuing to be large, and climate costs mounting, the case for a significant investment push has never been stronger. Yet the capacity to respond in many emerging markets and developing economies has eroded. Since the global financial crisis, investment growth has slowed to about half its pace in the 2000s, with both public and private investment weakening. Foreign direct investment inflows—a critical source of capital, technology, and managerial know-how—have also fallen sharply and become increasingly concentrated, leaving low-income countries with only a marginal share. The risks of further retrenchment are significant, as trade tensions, policy uncertainty, and elevated debt levels continue to weigh on investment. Reigniting momentum will require ambitious domestic reforms to strengthen institutions, rebuild macro-fiscal stability, and deepen trade and investment integration—the foundations of a supportive business climate. At the same time, international cooperation is indispensable. A renewed commitment to a predictable system of cross-border trade and investment flows, combined with scaled-up financial support and sustained technical assistance, is essential to help emerging markets and developing economies—especially low-income countries and economies in fragile and conflict situations—bridge financing gaps and implement the domestic reforms needed to restore investment as an engine of growth, jobs, and development.Publication The Evolution of Local Participatory Democracy in Nepal(Washington, DC: World Bank, 2025-11-05)Nepal is, according to its constitution, among the world’s most decentralized countries, with a long and complex tradition of local-level public participation. This paper traces the evolution of Nepal’s modern participatory institutions, examining the extent to which they are “induced” by external interventions versus being “organically” rooted in indigenous practices. The paper identifies three broad phases: an initial focus on participation in project implementation; a subsequent phase that expanded citizen engagement; and a third phase of citizen empowerment, culminating in the 2015 federal constitution, which granted unprecedented local autonomy. The analysis yields five key findings. First, over the past 50 years, successive reforms have progressively expanded opportunities for citizens to influence local decision-making. Second, these reforms have integrated traditional participatory mechanisms into formal institutions of local government. Third, although central-level initiatives exist, most participatory platforms continue to operate at the local level. Fourth, the federal constitution has created a new landscape of local democracy, embedding autonomy and accountability. Fifth, although they are still valued in many ethnic and territorial communities, traditional participatory practices are gradually disappearing. The paper concludes by offering policy recommendations to help donor agencies and governments strengthen Nepal’s democratic trajectory. It argues that effective interventions should build on Nepal’s deep participatory traditions while recognizing the constitutional reality of far-reaching local autonomy.

Publication A Spatial Perspective on Booms and Busts(World Bank, Washington, DC, 2023-08-30)This paper combines official subnational and remote-sensed data to uncover the relationships between business cycles in Türkiye and the corresponding changes in economic activity at lower levels of spatial aggregation. The objective is to document changes in the nature of growth within and across business cycles, with a focus on understanding how sectoral changes interact with within-country remoteness during each phase. The paper shows that: (i) the significant growth between 2010 and 2017 was bookended by recessions in which gross domestic product per capita fell more sharply the closer a province was to one of the two largest cities; (ii) the two recessions differed in terms of their sectoral impacts, with manufacturing declines inversely related to remoteness during the first recession and positively related during the second; (iii) there were large increases in the construction sector’s gross value added during the post-2009 rebound—consistent with unprecedented increases in nighttime light luminosity—with growth positively related to remoteness; and (iv) changes in nighttime light luminosity are correlated with changes in physical activity: a 10 percent increase in nighttime lights is associated with a 3.5 percent increase in construction output and a 1.5 percent increase in manufacturing output. Together, the results suggest that recessions and recoveries that may appear to be similar at a macroeconomic scale may be driven by very different changes at more disaggregated spatial scales and have varied impacts on regional convergence.Publication Adaptive Safety Nets for Rural Africa(World Bank, Washington, DC, 2020-07)This paper combines remote-sensed data and individual child, mother, and household-level data from the Demographic and Health Surveys for 5 countries in Sub-Saharan Africa to design a prototype drought-contingent targeting framework for use in scarce-data contexts. To accomplish this, the paper: (i) develops simple and easy-to-communicate measures of drought shocks; (ii) shows that droughts have a large impact on child stunting in these five countries, comparable, in size, to the effects of mother’s illiteracy or a fall to a lower wealth quintile; and (iii) shows that, in this context, decision trees and regressions predict stunting as accurately as complex machine learning methods that are not interpretable.2 Taken together, the analysis lends support to the idea that a data-driven approach may contribute to the design of a transparent and easy-to-use drought-contingent targeting frameworkPublication Adaptive Safety Nets for Rural Africa(World Bank, Washington, DC, 2019-12)This paper combines remote-sensed data and individual child-, mother-, and household-level data from the Demographic and Health Surveys for five countries in Sub-Saharan Africa (Malawi, Tanzania, Mozambique, Zambia, and Zimbabwe) to design a prototype drought-contingent targeting framework that may be used in scarce-data contexts. To accomplish this, the paper: (i) develops simple and easy-to-communicate measures of drought shocks; (ii) shows that droughts have a large impact on child stunting in these five countries -- comparable, in size, to the effects of mother's illiteracy and a fall to a lower wealth quintile; and (iii) shows that, in this context, decision trees and logistic regressions predict stunting as accurately (out-of-sample) as machine learning methods that are not interpretable. Taken together, the analysis lends support to the idea that a data-driven approach may contribute to the design of policies that mitigate the impact of climate change on the world's most vulnerable populations.Publication Getting Real? The Uneven Burden of Inflation across Households in Turkey(World Bank, Washington, DC, 2021-11)Inflation is typically measured using aggregate price indices that are based on bundles of goods and services sold or consumed by the “median” agent. In the case of households, in particular, budget shares vary substantially across income and demographic groups. Assessing how inflation behaves at the household level requires understanding how heterogenous changes in consumer prices affect household choices and well-being differently. In recent years, price increases have been particularly high in Turkey, with double-digit inflation starting in 2017 and intensifying in 2018 and 2020 due to exchange rate volatility, macroeconomic instability, and the economic disruption brought about by Covid-19. This paper calculates income-decile price indices to examine the inflation experience across income groups and discusses their implications for household welfare. Households in the first decile allocate nearly 70 percent of their budget to food and housing, twice as much as the corresponding share for the typical household in the upper decile. Inflation measures that consider these heterogeneities in expenditures show a higher burden for the poor in recent inflation episodes driven by rapid increases in food prices (2013, 2015 and 2019). In 2015, for instance, 342,000 additional people would have been deemed poor (an increase of 4.2 percent) had the poverty calculations taken into account the actual inflation experience of poor and vulnerable households. A methodological extension of the World Bank’s upper-middle-income poverty line ($5.50 2011 purchasing power parity) that takes into consideration the inflation experience of the bottom deciles yields higher poverty rates for Turkey every year between 2011 and 2020.Publication Characteristics and Determinants of Internal Labor Mobility in Ukraine(World Bank, Washington, DC, 2012-05)Over the past 20 years Ukraine experienced fundamental structural changes due to transition to a market economy and integration with the world. Transition reforms accompanied by the collapse of traditional trade and production links with the other republics of the former USSR and Comecon countries entailed asymmetric effects on regions, reflecting an uneven distribution of winners and losers from transition. Geographical mobility of labor is one of the major mechanisms (alongside with capital mobility, wage and price flexibility, and institutional mechanisms for redistributing income across regions) in facilitating regional adjustment to idiosyncratic shocks. The ability of workers to move freely from one geographical location to another inside the borders of their country, in pursuing the same occupation or changing occupations, is of particular importance for efficient matching of labor demand and supply and reducing structural unemployment. This paper seeks to fill gap in the literature on patterns of internal labor mobility in Ukraine, its main characteristics and potential for reducing persistent regional labor market disparities and imbalances in economic and human development. The next chapters of the paper are organized as follows: second chapter evaluates the magnitude of disparities in regional labor market and socio-economic indicators over time, with a special focus on its potential impact on decision of individuals to migrate to another settlement; third chapter provides an overview of the available data sources on internal labor mobility in Ukraine, quantifies internal migration based on aggregate administrative data, discusses its trends over time and compares it levels to those found in developed and transition economies. Fourth chapter provides multivariate statistical analysis of the determinants of inter-regional migration in 2002-2010 based on administrative region-level data. Fifth chapter summarizes the findings of empirical studies on determinants of the migration decision of Ukrainians. Sixth chapter examines short-term labor migration including everyday commuting in 2005-2010 and measures its covariates using individual-level Labor Force Survey (LFS) data. Seventh chapter summarizes the main findings and concludes.

Publication Commodity Markets Outlook, October 2025(Washington, DC: World Bank, 2025-10-29)Commodity prices are expected to decline by about 7 percent overall this year, reflecting subdued global economic activity, elevated trade tensions and policy uncertainty, ample global supply of oil, and weather-related supply shocks. In 2026, commodity prices are forecast to fall by a further 7 percent, a fourth consecutive year of decline, as global growth remains sluggish and the oil market oversupplied. Energy price movements are envisaged to continue contributing to global disinflation in 2026. Metals and minerals prices are expected to remain stable in 2026, while agricultural prices are projected to edge down, primarily due to strong supply conditions. Precious metals prices are expected to rise another 5 percent, after a historically large, investment-driven rally of about 40 percent in 2025. Risks to the commodity price projections are tilted to the downside. Key downside risks include weaker-than-expected global growth, a longer-than-assumed period of economic policy uncertainty, and additional oversupply of oil. Upside risks include intensifying geopolitical tensions, the market impact of additional oil sanctions, supply reductions stemming from additional trade restrictions, unfavorable weather conditions, faster-than-expected rollout of new data centers. Commodity price volatility in recent years has revived interest in supply management via international commodity agreements. Historical experience, however, shows that the most effective policy is to promote diversification, innovation, transparency, and market-based pricing—measures that build lasting resilience to commodity price volatility.Publication The Container Port Performance Index 2020 to 2024: Trends and Lessons Learned(Washington, DC: World Bank, 2025-09-22)The Container Port Performance Index (CPPI) provides a global benchmark of how container ports perform in handling vessel calls. Developed jointly by the World Bank and S&P Global Market Intelligence, it measures the time ships spend in port and relates this to the number of containers moved during that time. This approach makes the CPPI a unique diagnostic tool that can highlight patterns in port operations and shed light on global and regional supply chain dynamics. Now in its fifth edition, the CPPI report covers the period from 2020 to 2024. It builds on a well-established methodology to generate scores for more than 400 container ports worldwide. Over time, the CPPI has become a trusted reference point for policymakers, industry stakeholders, and researchers who seek to understand how ports adapt to shocks, recover from disruptions, and identify opportunities for investments, reform and modernization. A major innovation in this edition is the introduction of multi-year trend analysis. Rather than presenting annual snapshots, the report now tracks how CPPI scores have changed across five years. This longitudinal perspective reveals shifts in port performance, showing where scores have risen, fallen, or remained stable. By linking these movements to external factors, the CPPI offers insights into how global and regional supply chains evolve under pressure. The results clearly mirror the crises that have shaken global trade. During the COVID-19 pandemic, CPPI scores in different regions declined sharply as congestion, equipment shortages, and delays overwhelmed many ports. By 2023, global averages rebounded in parallel with easing freight markets and reduced congestion. Yet 2024 brought new challenges: the Red Sea crisis disrupted major trade lanes, while climate-related constraints at the Panama Canal added further stress. These shocks were reflected in lower global and several regional average scores, underscoring the vulnerability of maritime transport to geopolitical and environmental events. The CPPI is not about comparing one port against another, but about understanding changes in performance over time. Ports that improved their scores often did so by reducing time at anchor, optimizing berth operations, investing in digital tools, and strengthening coordination across logistics partners. The evidence confirms that improvements are possible across ports of all sizes, and that rising scores are linked to deliberate actions to minimize time in port relative to containers moved. By consolidating five years of results, this edition transforms the CPPI into a long-term reference point. It shows how global crises have affected shipping, how different regions have adapted, and what lessons can be drawn for future resilience. The World Bank and S&P Global Market Intelligence remain committed to maintaining the CPPI as a global public good, providing transparency, comparability, and practical insights to support more reliable and sustainable maritime supply chains.Publication Global Economic Prospects, June 2025(Washington, DC: World Bank, 2025-06-10)The global economy is facing another substantial headwind, emanating largely from an increase in trade tensions and heightened global policy uncertainty. For emerging market and developing economies (EMDEs), the ability to boost job creation and reduce extreme poverty has declined. Key downside risks include a further escalation of trade barriers and continued policy uncertainty. These challenges are exacerbated by subdued foreign direct investment into EMDEs. Global cooperation is needed to restore a more stable international trade environment and scale up support for vulnerable countries grappling with conflict, debt burdens, and climate change. Domestic policy action is also critical to contain inflation risks and strengthen fiscal resilience. To accelerate job creation and long-term growth, structural reforms must focus on raising institutional quality, attracting private investment, and strengthening human capital and labor markets. Countries in fragile and conflict situations face daunting development challenges that will require tailored domestic policy reforms and well-coordinated multilateral support.Publication Missed Opportunities(World Bank, Washington, DC, 2018-07-11)Too many girls drop out of school prematurely, especially in low income countries. Low educational attainment for girls has negative consequences not only for them, but also for their children and household, as well as for their community and society. This study documents the potential impacts of educational attainment for girls and women in six domains: (1) earnings and standards of living; (2) child marriage and early childbearing; (3) fertility and population growth; (4) health, nutrition, and well-being; (5) agency and decision-making; and (6) social capital and institutions. The results are sobering: the potential economic and social costs of not educating girls are large. Low educational attainment reduces expected earnings in adulthood, and it depresses labor force participation, leading to lower standards of living. When girls drop out of school prematurely, they are much more likely to marry as children, and have their first child before the age of 18 when they may not yet be ready to be wife and mothers. This in turn is associated with higher rates of fertility and population growth, which in low income countries are major impediments for reaping the benefits of the demographic dividend. Low educational attainment is also associated with worse health and nutrition outcomes for women and their children, leading among others to higher under-five mortality and stunting. Girls who drop out of school also suffer in adulthood from a lack of agency and decision-making ability within the household, and in society more generally. They are also less likely to report engaging in altruistic behaviors such as donating to charity, volunteering, or helping others. Finally, when girls and women are better educated, they may be better able to assess the quality of the basic services they rely on and the quality of their country’s institutions and leaders. These negative impacts have large economic costs, leading among others to losses in human capital wealth (future lifetime earnings of the labor force) estimated at $15 trillion to $30 trillion. Educating girls is not only the right thing to do: it is also a smart economic investment.Publication Reboot Development: The Economics of a Livable Planet(Washington, DC: World Bank, 2025-09-01)“Reboot Development: The Economics of a Livable Planet” explores how the foundational natural endowments of land, air, and water—long taken for granted—are under growing threat, putting at risk the very progress they helped create. For generations, natural resources have powered development, supporting health, food, energy, and economic opportunity. Today, strains on these resources are intensifying. This report argues that failing to maintain a livable planet is not merely a distant environmental concern, but a present economic threat. Drawing on new data, the report shows that over 90 percent of the world is exposed to poor air quality, degraded land, or water stress. Loss of forests cuts rainfall, dries soils, and worsens droughts, costing billions of dollars. The nitrogen paradox emerges—fertilizers boost yields but overuse in some regions harms crops and ecosystems. Meanwhile, air and water pollution silently damage health, productivity, and cognition, sapping human potential. The report warns that these hidden costs are too large to ignore. Yet the message is not one of constraint but of possibility. Nature, when wisely stewarded, can drive growth, create jobs, and build resilience. The report shows that more efficient resource use—like better nitrogen management and forest restoration—yields benefits that far exceed the costs. It also urges a shift to cleaner sectors and producing “better things,” noting that these provide new sources of growth, creating more jobs per dollar invested. The findings are clear: Investing in nature is not only good for the planet, it is smart development.
