Abstract
The international community is paying increased attention to the 25 percent of the world's population that lives in fragile and conflict affected settings, acknowledging that these settings represent daunting development challenges. To deliver better results on the ground, it is necessary to improve the understanding of the impacts and effectiveness of development interventions operating in contexts of conflict and fragility. This paper argues that it is both possible and important to carry out impact evaluations even in settings of violent conflict, and it presents some examples from a collection of impact evaluations of conflict prevention and peacebuilding interventions. The paper examines the practices of impact evaluators in the peacebuilding sector to see how they address evaluation design, data collection, and conflict analysis. Finally, it argues that such evaluations are crucial for testing assumptions about how development interventions affect change -- the so-called "theory of change" -- which is important for understanding the results on the ground.

Publication The Future of Poverty(Washington, DC: World Bank, 2025-07-15)Climate change is increasingly acknowledged as a critical issue with far-reaching socioeconomic implications that extend well beyond environmental concerns. Among the most pressing challenges is its impact on global poverty. This paper projects the potential impacts of unmitigated climate change on global poverty rates between 2023 and 2050. Building on a study that provided a detailed analysis of how temperature changes affect economic productivity, this paper integrates those findings with binned data from 217 countries, sourced from the World Bank’s Poverty and Inequality Platform. By simulating poverty rates and the number of poor under two climate change scenarios, the paper uncovers some alarming trends. One of the primary findings is that the number of people living in extreme poverty worldwide could be nearly doubled due to climate change. In all scenarios, Sub-Saharan Africa is projected to bear the brunt, contributing the largest number of poor people, with estimates ranging between 40.5 million and 73.5 million by 2050. Another significant finding is the disproportionate impact of inequality on poverty. Even small increases in inequality can lead to substantial rises in poverty levels. For instance, if every country’s Gini coefficient increases by just 1 percent between 2022 and 2050, an additional 8.8 million people could be pushed below the international poverty line by 2050. In a more extreme scenario, where every country’s Gini coefficient increases by 10 percent between 2022 and 2050, the number of people falling into poverty could rise by an additional 148.8 million relative to the baseline scenario. These findings underscore the urgent need for comprehensive climate policies that not only mitigate environmental impacts but also address socioeconomic vulnerabilities.Publication Central Bank Independence and Sovereign Borrowing(Washington, DC: World Bank, 2025-07-25)This paper studies the impact of central bank independence on sovereign borrowing, using an index that captures institutional constraints on central bank lending to the government across 155 countries from 1972 to 2023. The findings show that tighter lending to the executive significantly reduces sovereign interest rates and raises the debt-to-gross domestic product ratio in developing countries. These effects reflect the executive’s improved ability to borrow at lower costs under greater central bank independence. The results are robust to multiple tests, but there are no significant effects in advanced economies. From a policy perspective, the results highlight the key role of independent central banks as catalysts for reducing governments’ borrowing costs and enhancing the government’s borrowing capacity.Publication Disentangling the Key Economic Channels through Which Infrastructure Affects Jobs(Washington, DC: World Bank, 2025-04-03)This paper takes stock of the literature on infrastructure and jobs published since the early 2000s, using a conceptual framework to identify the key channels through which different types of infrastructure impact jobs. Where relevant, it highlights the different approaches and findings in the cases of energy, digital, and transport infrastructure. Overall, the literature review provides strong evidence of infrastructure’s positive impact on employment, particularly for women. In the case of electricity, this impact arises from freeing time that would otherwise be spent on household tasks. Similarly, digital infrastructure, particularly mobile phone coverage, has demonstrated positive labor market effects, often driven by private sector investments rather than large public expenditures, which are typically required for other large-scale infrastructure projects. The evidence on structural transformation is also positive, with some notable exceptions, such as studies that find no significant impact on structural transformation in rural India in the cases of electricity and roads. Even with better market connections, remote areas may continue to lack economic opportunities, due to the absence of agglomeration economies and complementary inputs such as human capital. Accordingly, reducing transport costs alone may not be sufficient to drive economic transformation in rural areas. The spatial dimension of transformation is particularly relevant for transport, both internationally—by enhancing trade integration—and within countries, where economic development tends to drive firms and jobs toward urban centers, benefitting from economies scale and network effects. Turning to organizational transformation, evidence on skill bias in developing countries is more mixed than in developed countries and may vary considerably by context. Further research, especially on the possible reasons explaining the differences between developed and developing economies, is needed.Publication Crowding Out and Banking Crises(Washington, DC: World Bank, 2025-07-22)This paper studies the effect of government issuance on firm issuance during banking crises using transaction-level bond and loan data from 66 countries between 1991 and 2017. Governments rarely issue loans, preferring to issue in bond markets. In contrast, firms receive most of their financing from banks. During banking crises, as the supply of domestic loans decreases, firms switch to issuing bonds in domestic markets. The paper uses a novel instrument based on maturing debt to overcome the potential endogeneity of government issuance. The findings show that firms must compete with the government for funds in the domestic bond market and are crowded out from this market as a result. This happens not only in developing countries, but in advanced countries as well. The paper also shows that firms with the ability to tap international debt markets switch to these markets when crowding out occurs in domestic bond markets. Lastly, the paper shows that more developed domestic bond markets mitigate, but do not eliminate, the degree to which crowding out occurs.Publication Designing and Analyzing Powerful Experiments(Washington, DC: World Bank, 2025-07-22)This paper offers practical advice on how to improve statistical power in randomized experiments through choices and actions researchers can take at the design, implementation, and analysis stages. At the design stage, the choice of estimand, choice of treatment, and decisions that affect the residual variance and intra-cluster correlation can all affect power for a given sample size. At the implementation stage, researchers can boost power through increasing compliance with treatment, reducing attrition, and improving outcome measurement. At the analysis stage, power can be increased through using different test statistics or estimands, through the choice of control variables, and through incorporating informative priors in a Bayesian analysis. A key message is that it does not make sense to talk of “the” power of an experiment. A study can be well-powered for one outcome or estimand, but not others, and a fixed sample size can yield very different levels of power depending on researcher decisions.

Publication A Comparative Study of Ex-Combatant Reintegration in the African Great Lakes Region(World Bank, Washington, DC, 2014-07)This report is structured in three parts. Part one is a summary document, including: (i) an executive summary (ii) an introduction; (iii) a review of core concepts of reintegration that will be referred to in this study; (iv) a meta-analysis of reintegration process¬es in the Great Lakes Region (GLR) vis-à-vis the conceptual discussion; and (v) conclusions to the summary document. Part two (annex one) comprises an in-depth review and analysis of data on the reintegration process-es of ex-combatants across the GLR. Part three (annex two) is an in-depth analysis of community dynamics across the GLR. In brief, part one of the study is a meta-analytical and knowledge-focused piece that reflects more broadly on the detailed analysis of the datasets presented in annexes one and two, therefore, this part can be read as a freestanding report. However, it’s worth noting that any reading will benefit significantly from exploring the detailed findings in annexes one and two.Publication Improving Security in Violent Conflict Settings(World Bank, Washington, DC, 2010-11-01)Violent conflict is the multifaceted and cyclical problem that the international community is trying to grapple with. To date, there has been a clear hierarchy concerning what forms of violence are seen to matter most, with political violence that threatens the state taking pole position. In examining this argument, this paper sets out a number of issues relating to security and justice definitions. It will then examine some of the problems associated with placing conflict into a box-set typology: mass violence associated with war and genocide carries unique features but also spawns new challenges which are often being ignored. The paper will then examine in brief some of the measures used by communities, governmental actors and international partners in contending with violence before outlining some key conclusions and recommendations. In reading this paper two further points need be borne in mind: 1) this does not provide a comprehensive overview of violence and security - that is the role of the World Development Report (WDR) itself, and 2) this paper does not present fresh research, but more an overview, along with the other papers in the security-justice series, of some of the key issues confronting policy makers in the domain of security and development.Publication Measuring Violent Conflict in Micro-Level Surveys(World Bank, Washington, DC, 2016-02)This paper reviews both current practices and common challenges of measuring the causes, functioning, and consequences of violent conflict at the micro-level. The authors review existing conflict -- and violence-related survey questionnaires, with a particular focus on the World Bank's Living Standard Measurement Surveys. Further, they discuss methodological challenges associated with empirical work in conflict-affected areas—such as operationalizing a definition of conflict, using the appropriate units of analysis, deciding on the timing of the survey, dealing with data biases and conducting surveys in an ethically sound manner—and propose ways to improve the usefulness of existing surveys to analyze conflict processes at the micro-level. Violent conflict, households, survey methods, questionnaire design.Publication The Post Conflict Fund(World Bank, Washington, DC, 2004-12-01)The Operations Evaluation Department (OED) is an independent unit within the World Bank. The goals of evaluation are to learn from experience, to provide an objective basis for assessing the results of the Bank’s work, and to provide accountability in the achievement of its objectives. This report on the Post-Conflict Fund (PCF) is one of twenty six case studies that have been prepared as source material for the second phase of OED’s independent evaluation of the Bank’s involvement in global programs. The program objective is to position the Bank through constructive engagement in conflict-affected countries where normal instruments and budget provisions cannot apply. The key findings are as follows : (i) a flexible instrument such as the PCF serves the needs that the Bank’s numerous instruments do not fulfill in conflict-affected countries; (ii) yet if the policy guidelines under which it operates are too flexible, and the DGF criteria are ambiguous and insufficiently enforced, the instrument can be less than fully effective; (iii)Programs can continue over several years without a results-based framework and strong monitoring and evaluation; (iv) as currently designed, the country-by-country approach of the program does not sufficiently generate broader cross-country lessons and does not exploit the program’s full potential to serve the Bank and its partners strategically; and (v) a global partnership program on conflict-affected countries with partners at the governance level might help the Bank, United Nations (UN) agencies, and other stakeholders to better respond to the transition from relief, to rehabilitation and reconstruction and development. Finally, this being an OED evaluation, it focuses primarily on the Bank’s strategic role and performance in playing up to its comparative advantage relative to other partners in each program.

Publication The Container Port Performance Index 2023(Washington, DC: World Bank, 2024-07-18)The Container Port Performance Index (CPPI) measures the time container ships spend in port, making it an important point of reference for stakeholders in the global economy. These stakeholders include port authorities and operators, national governments, supranational organizations, development agencies, and other public and private players in trade and logistics. The index highlights where vessel time in container ports could be improved. Streamlining these processes would benefit all parties involved, including shipping lines, national governments, and consumers. This fourth edition of the CPPI relies on data from 405 container ports with at least 24 container ship port calls in the calendar year 2023. As in earlier editions of the CPPI, the ranking employs two different methodological approaches: an administrative (technical) approach and a statistical approach (using matrix factorization). Combining these two approaches ensures that the overall ranking of container ports reflects actual port performance as closely as possible while also being statistically robust. The CPPI methodology assesses the sequential steps of a container ship port call. ‘Total port hours’ refers to the total time elapsed from the moment a ship arrives at the port until the vessel leaves the berth after completing its cargo operations. The CPPI uses time as an indicator because time is very important to shipping lines, ports, and the entire logistics chain. However, time, as captured by the CPPI, is not the only way to measure port efficiency, so it does not tell the entire story of a port’s performance. Factors that can influence the time vessels spend in ports can be location-specific and under the port’s control (endogenous) or external and beyond the control of the port (exogenous). The CPPI measures time spent in container ports, strictly based on quantitative data only, which do not reveal the underlying factors or root causes of extended port times. A detailed port-specific diagnostic would be required to assess the contribution of underlying factors to the time a vessel spends in port. A very low ranking or a significant change in ranking may warrant special attention, for which the World Bank generally recommends a detailed diagnostic.Publication Digital Progress and Trends Report 2023(Washington, DC: World Bank, 2024-03-05)Digitalization is the transformational opportunity of our time. The digital sector has become a powerhouse of innovation, economic growth, and job creation. Value added in the IT services sector grew at 8 percent annually during 2000–22, nearly twice as fast as the global economy. Employment growth in IT services reached 7 percent annually, six times higher than total employment growth. The diffusion and adoption of digital technologies are just as critical as their invention. Digital uptake has accelerated since the COVID-19 pandemic, with 1.5 billion new internet users added from 2018 to 2022. The share of firms investing in digital solutions around the world has more than doubled from 2020 to 2022. Low-income countries, vulnerable populations, and small firms, however, have been falling behind, while transformative digital innovations such as artificial intelligence (AI) have been accelerating in higher-income countries. Although more than 90 percent of the population in high-income countries was online in 2022, only one in four people in low-income countries used the internet, and the speed of their connection was typically only a small fraction of that in wealthier countries. As businesses in technologically advanced countries integrate generative AI into their products and services, less than half of the businesses in many low- and middle-income countries have an internet connection. The growing digital divide is exacerbating the poverty and productivity gaps between richer and poorer economies. The Digital Progress and Trends Report series will track global digitalization progress and highlight policy trends, debates, and implications for low- and middle-income countries. The series adds to the global efforts to study the progress and trends of digitalization in two main ways: · By compiling, curating, and analyzing data from diverse sources to present a comprehensive picture of digitalization in low- and middle-income countries, including in-depth analyses on understudied topics. · By developing insights on policy opportunities, challenges, and debates and reflecting the perspectives of various stakeholders and the World Bank’s operational experiences. This report, the first in the series, aims to inform evidence-based policy making and motivate action among internal and external audiences and stakeholders. The report will bring global attention to high-performing countries that have valuable experience to share as well as to areas where efforts will need to be redoubled.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 Global Economic Prospects, January 2025(Washington, DC: World Bank, 2025-01-16)Global growth is expected to hold steady at 2.7 percent in 2025-26. However, the global economy appears to be settling at a low growth rate that will be insufficient to foster sustained economic development—with the possibility of further headwinds from heightened policy uncertainty and adverse trade policy shifts, geopolitical tensions, persistent inflation, and climate-related natural disasters. Against this backdrop, emerging market and developing economies are set to enter the second quarter of the twenty-first century with per capita incomes on a trajectory that implies substantially slower catch-up toward advanced-economy living standards than they previously experienced. Without course corrections, most low-income countries are unlikely to graduate to middle-income status by the middle of the century. Policy action at both global and national levels is needed to foster a more favorable external environment, enhance macroeconomic stability, reduce structural constraints, address the effects of climate change, and thus accelerate long-term growth and development.Publication Business Ready 2024(Washington, DC: World Bank, 2024-10-03)Business Ready (B-READY) is a new World Bank Group corporate flagship report that evaluates the business and investment climate worldwide. It replaces and improves upon the Doing Business project. B-READY provides a comprehensive data set and description of the factors that strengthen the private sector, not only by advancing the interests of individual firms but also by elevating the interests of workers, consumers, potential new enterprises, and the natural environment. This 2024 report introduces a new analytical framework that benchmarks economies based on three pillars: Regulatory Framework, Public Services, and Operational Efficiency. The analysis centers on 10 topics essential for private sector development that correspond to various stages of the life cycle of a firm. The report also offers insights into three cross-cutting themes that are relevant for modern economies: digital adoption, environmental sustainability, and gender. B-READY draws on a robust data collection process that includes specially tailored expert questionnaires and firm-level surveys. The 2024 report, which covers 50 economies, serves as the first in a series that will expand in geographical coverage and refine its methodology over time, supporting reform advocacy, policy guidance, and further analysis and research.
