Abstract
This paper examines the growth effects of different dimensions of international trade integration -- notably, volume, diversification, and natural resource dependence -- in Sub-Saharan Africa. First, the paper documents the recent trends in these foreign trade dimensions for the region and the traditional sources of growth. Second, it empirically estimates the impact of trade integration on growth per worker and the sources of growth; that is, growth of capital per worker and total factor productivity growth. To accomplish this task, the analysis uses a sample of non-overlapping five-year period observations for 173 countries from 1975 to 2014. The econometric evidence shows that increased trade openness, greater export production diversification, and reduced export dependence from natural resources will have a positive causal impact on economic growth. These effects will be mainly transmitted through faster capital accumulation or enhanced total factor productivity growth. Finally, the paper finds that, despite the progress exhibited in trade openness and diversification over the past decade, there are still potential benefits that can be accrued if countries were to deepen their integration to world trade.

    Climate and Social Sustainability in Fragility, Conflict, and Violence Contexts
    (Washington, DC: World Bank, 2026-01-07) Cuesta Leiva, Jose Antonio; Huff, Connor
    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.

    The Macroeconomic Implications of Climate Change Impacts and Adaptation Options
    (Washington, DC: World Bank, 2025-05-29) Abalo, Kodzovi; Boehlert, Brent; Bui, Thanh; Burns, Andrew; Castillo, Diego; Chewpreecha, Unnada; Haider, Alexander; Hallegatte, Stephane; Jooste, Charl; McIsaac, Florent; Ruberl, Heather; Smet, Kim; Strzepek, Ken
    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.

    Institutional Capacity for Policy Implementation: An Analytical Framework
    (Washington, DC: World Bank, 2026-01-07) Kim, Galileu; Kumar, Tanu; Ramalho, Rita; Russell, Stuart
    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.

    South Africa’s Fragmented Cities: The Unequal Burden of Labor Market Frictions
    (Washington, DC: World Bank, 2026-01-08) Baez, Javier E.; Kshirsagar, Varun
    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.

    Investment in Emerging and Developing Economies
    (Washington, DC: World Bank, 2026-01-07) Adarov, Amat; Kose, M. Ayhan; Vorisek, Dana
    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.

    Trade Integration, Export Patterns, and Growth in Sub-Saharan Africa
    (World Bank, Washington, DC, 2020-01) Calderon, Cesar; Cantu, Catalina; Zeufack, Albert G.
    This paper examines systematically the growth effects of trade integration in Sub-Saharan Africa. It complements and improves upon the empirical literature in two aspects: first, it jointly estimates the impact of different dimensions of trade integration, namely, trade volumes, export/trade patterns by product (primary and manufacturing goods), and by destination (inter- and intra-regional). Second, it estimates the impact of trade integration on economic growth and its sources, that is, capital accumulation and total factor productivity growth. The analysis finds causal evidence that trade integration fosters growth. Additionally, manufacturing trade boosts growth and trade in primary goods hampers growth. Doubling the manufacturing trade share in Sub-Saharan Africa's gross domestic product would increase growth by 1.9 percentage points per year, while increases in primary trade reduce growth by 1 percentage point. This impact is mainly transmitted through lower capital accumulation. Finally, inter- and intra-regional trade have a positive impact on growth in Sub-Saharan Africa. Doubling inter-regional trade will increase growth by 1.9 percentage points, and the same increase for intra-regional trade enhances growth by 0.6 percentage points. The effects of inter-regional trade are transmitted primarily through capital accumulation, while those of intra-regional trade are channeled through enhanced total factor productivity growth.

    Trade and Economic Growth : Evidence on the Role of Complementarities for CAFTA-DR Countries
    (2010-09-01) Calderón, César; Poggioa, Virginia
    This paper examines the effects of trade on growth among Central America-Dominican Republic Free Trade Agreement countries. To accomplish this task, the authors collected a panel data set of 136 countries over 1960-2010, and estimated cross-country growth regressions using an econometric methodology that accounts for unobserved effects and the likely endogeneity of the growth determinants. Following recent empirical efforts, they tested whether the impact of trade openness on growth may be more effective after surpassing a "minimum threshold" in specific areas closely related to economic development. The analysis finds not only that there is a robust causal link from trade to growth, but also that the growth benefits from trade are larger in countries with higher levels of education and innovation, deeper financial markets, a stronger institutional framework, more developed infrastructure networks, a high level of integration with world capital markets, and less stringent economic regulations. On average, rising trade has benefited growth in Central America-Dominican Republic Free Trade Agreement countries. However, the lack of progress in structural reforms has not allowed these countries to maximize the potential benefits from trade.

    The Business Environment in Southern Africa : Issues in Trade and Market Integration - Summary
    (World Bank, 2010-12-31) World Bank
    This report assesses some of the key barriers to greater trade and factor market integration in the Southern Africa Development Community (SADC). The SADC has been a free trade area since 2008, and has an ambitious agenda for further trade integration. This report assesses the roles that cross-country differences in business environments have had in impeding cross-border trade flows and the cross-border integration of credit markets and the labor market based on the analysis of microeconomic data on firms and households. The aim of the assessment is to help inform the policy and business environment harmonization agenda of the community. The full report discusses and illustrates the use of price data in monitoring intraregional trade integration. The report evaluates the extent of integration of labor markets among members the statistical agencies of which regularly collect the minimum data required for this purpose, which are South Africa, Mauritius, Tanzania, and Zambia. The results show that, although there is considerable integration of South Africa's labor market with many others in the region, the degree of integration is rather low. This reflects the fact that both trade and capital flows are far more restricted in the region than in places where there is greater cross-border labor market integration.

    Trade Facilitation, Value Creation, and Competiveness : Policy Implications for Vietnam's Economic Growth, Volume 1
    (World Bank, Washington, DC, 2013-07-15) Pham, Duc Minh; Mishra, Deepak; Cheong, Kee-Cheok; Arnold, John; Trinh, Anh Minh; Ngo, Huyen Thi Ngoc; Nguyen, Hien Thi Phuong
    This report explores the role of trade facilitation and logistics in driving export and ultimately national competitiveness. It posits that this area of trade consists of three interrelated pillars: (i) transport infrastructure and logistics services; (ii) regulatory procedures for exports and imports; and (iii) supply chain organization. Transport infrastructure and logistics services relate to the physical aspects of trade flows. Logistics services include a variety of services, the most important of which are transportation, storage and consolidation. This summary is organized into nine sections. After the introduction, section two presents the conceptual framework for this study. The economic context under which trade facilitation is discussed is outlined in section three. It describes Vietnam's evolving structure of trade and competitiveness. The country's trade logistics is part of this structure and this is germane to understanding the key issues and solutions proposed. This is followed by discussion of the three pillars of trade facilitation in sections four to six and then section seven presents the institutional framework underpinning these pillars. Section eight then pulls together the diverse roles of government, such as setting policies, acting as regulator, and being the facilitator working in collaboration with key stakeholders. The conclusion, section nine, suggests a set of recommendations.

    Afghanistan Diagnostics Trade Integration Study
    (Washington, DC, 2012-11) World Bank
    Trade enables countries to import ideas and technologies, realize comparative advantages and economies of scale, and foster competition and innovation, which in turn increases productivity and achieves higher sustainable employment and economic growth. Countries open to international trade tend to provide more opportunities to their people, and grow faster. Afghanistan could derive far more benefit from its international trade opportunities than it does at present. This Diagnostics Trade Integration Study (DTIS) report is intended to identify concrete policy actions in three areas of endeavor: lowering the transaction costs of trade, increasing Afghanistan's competitiveness in world markets, and providing an analytical foundation for Afghanistan's national trade strategy. The study examines how to do this, looking not only at trade performance and policy, but also at three sectors with great export potential: agriculture, gemstones and carpets, as well as the investment climate, customs as a driver of trade facilitation, and on promoting infrastructure services. All five chapters in this report provide a detailed and comprehensive analysis of trade issues intended to reduce the transaction costs of trade. Growth in Afghanistan has been strong and volatile because of its heavy reliance on agriculture. Now it faces a transition: prospects of a drawdown of international military forces and a decline in civilian aid by 2014. Security issues and political instability could undermine Afghanistan's Transition. Such threats could harm not only economic growth, but deterioration would repel private-sector investment.

    Reboot Development: The Economics of a Livable Planet
    (Washington, DC: World Bank, 2025-09-01) Damania, Richard; Ebadi, Ebad; Mayr, Kentaro; Russ, Jason; Zaveri, Esha
    “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.

    Digital Africa
    (Washington, DC: World Bank, 2023-03-13) Begazo, Tania; Dutz, Mark Andrew; Blimpo, Moussa
    All African countries need better and more jobs for their growing populations. "Digital Africa: Technological Transformation for Jobs" shows that broader use of productivity-enhancing, digital technologies by enterprises and households is imperative to generate such jobs, including for lower-skilled people. At the same time, it can support not only countries’ short-term objective of postpandemic economic recovery but also their vision of economic transformation with more inclusive growth. These outcomes are not automatic, however. Mobile internet availability has increased throughout the continent in recent years, but Africa’s uptake gap is the highest in the world. Areas with at least 3G mobile internet service now cover 84 percent of Africa’s population, but only 22 percent uses such services. And the average African business lags in the use of smartphones and computers as well as more sophisticated digital technologies that catalyze further productivity gains. Two issues explain the usage gap: affordability of these new technologies and willingness to use them. For the 40 percent of Africans below the extreme poverty line, mobile data plans alone would cost one-third of their incomes—in addition to the price of access devices, apps, and electricity. Data plans for small- and medium-size businesses are also more expensive than in other regions. Moreover, shortcomings in the quality of internet services—and in the supply of attractive, skills-appropriate apps that promote entrepreneurship and raise earnings—dampen people’s willingness to use them. For those countries already using these technologies, the development payoffs are significant. New empirical studies for this report add to the rapidly growing evidence that mobile internet availability directly raises enterprise productivity, increases jobs, and reduces poverty throughout Africa. To realize these and other benefits more widely, Africa’s countries must implement complementary and mutually reinforcing policies to strengthen both consumers’ ability to pay and willingness to use digital technologies. These interventions must prioritize productive use to generate large numbers of inclusive jobs in a region poised to benefit from a massive, youthful workforce—one projected to become the world’s largest by the end of this century.

    Maldives Country Climate and Development Report
    (Washington, DC: World Bank, 2024-06-27) World Bank Group
    The Maldives Country Climate and Development Report (CCDR) analyses climate change and development challenges and opportunities in the country in an integrated manner. The report focuses on the Maldives achieving six high-level objectives: (1) improving macroeconomic stability and fiscal space to enable climate action, (2) mobilizing climate finance, (3) enhancing the climate resilience of islands and infrastructure, (4) enhancing the climate resilience of ecosystems, (5) enhancing the climate resilience of livelihoods (fishers and tourism), and (6) unlocking the development benefits from green transitions in energy, mobility, and waste sectors. The CCDR contributes original research into key dimensions of climate resilience in the Maldives, including sea-level rise impact modeling on land, infrastructure, and economic activities; ocean heating impact modeling on fishing and coral reef degradation; and survey work to understand climate change adaptation efforts of and associated challenges faced by tourist resorts. The recommendations presented in the CCDR will support the country in facilitating its climate resilience and green transitions, giving due consideration to the macroeconomic vulnerabilities at the time of releasing the report.

    Resilient Telecommunications Infrastructure - A Practitioner's Guide
    (Washington, DC: World Bank, 2024-12-18) World Bank
    Connectivity drives economic development and underpins critical services in the aftermath of disastrous weather events or earthquakes. However, nearly all types of climate and natural hazards can cause damage to telecommunications (telecom) networks and threaten service delivery. For countries that experience multiple types of climate hazards, building telecom infrastructure is a challenge for public practitioners and telecom operators. This guide provides recommendations for practitioners in designing, preparing, and implementing resilient telecom infrastructure projects. For instance, resilience-building measures, such as risk analysis, redundancy, backup power, customization, and disaster planning, are important for strengthening the resilience of telecom infrastructure deployments. While no single intervention will make telecom infrastructure fully resilient, investment in a range of coordinated actions can reduce the probability of failure and enable operators to maintain acceptable service in the face of increasing climate hazards.
