Abstract
Earlier studies have shown that United Nations peace operations make a positive contribution to peacebuilding efforts after civil wars. But do these effects carry over to the period after the peacekeepers leave? And how do the effects of UN peace operations interact with other determinants of peacebuilding in the long run? The author addresses these questions using a revised version of the Doyle and Sambanis dataset and applying different estimation methods to estimate the short-term and long-term effects of UN peace missions. He finds that UN missions have robust, positive effects on peacebuilding in the short term. UN missions can help parties implement peace agreements but the UN cannot fight wars, and UN operations contribute more to the quality of the peace where peace is based on participation, than to the longevity of the peace, where peace is simply the absence of war. The effects of UN missions are also felt in the long run, but they dissipate over time. What is missing in UN peacebuilding is a strategy to foster the self-sustaining economic growth that could connect increased participation with sustainable peace.

    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.

    Global Poverty Revisited Using 2021 PPPs and New Data on Consumption
    (Washington, DC: World Bank, 2025-06-05) Foster, Elizabeth; Jolliffe, Dean Mitchell; Ibarra, Gabriel Lara; Lakner, Christoph; Tettah-Baah, Samuel
    Recent improvements in survey methodologies have increased measured consumption in many low- and lower-middle-income countries that now collect a more comprehensive measure of household consumption. Faced with such methodological changes, countries have frequently revised upward their national poverty lines to make them appropriate for the new measures of consumption. This in turn affects the World Bank’s global poverty lines when they are periodically revised. The international poverty line, which is based on the typical poverty line in low-income countries, increases by around 40 percent to $3.00 when the more recent national poverty lines as well as the 2021 purchasing power parities are incorporated. The net impact of the changes in international prices, the poverty line, and new survey data (including new data for India) is an increase in global extreme poverty by some 125 million people in 2022, and a significant shift of poverty away from South Asia and toward Sub-Saharan Africa. The changes at higher poverty lines, which are more relevant to middle-income countries, are mixed.

    Geopolitical Fragmentation and Friendshoring
    (Washington, DC: World Bank, 2025-06-26) Grover, Arti; Vézina, Pierre-Louis
    This paper examines the relationship between geopolitical fragmentation and friendshoring of foreign investments over time, countries, and sectors. The analysis uses comprehensive data on foreign direct investments covering greenfield projects, mergers and acquisitions, and stocks of affiliates, as well as data on four alternative measures of geopolitical distance between countries. The gravity estimations suggest that, first, geopolitical differences have a negative effect on foreign investments and the magnitude has heightened in the post-pandemic period compared to a decade ago. Second, it is primarily the companies from advanced Western economies whose foreign investment decisions are increasingly shaped by friendshoring forces. Finally, the paper shows that friendshoring is not only confined to strategic industries, implying that allocations of foreign direct investments may not solely reflect national security or resilience considerations.

    Soaring Food Prices Threaten Recent Economic Gains in the EU
    (Washington, DC: World Bank, 2025-07-02) Robayo, Monica; Lucchetti, Leonardo Ramiro; Delgado-Prieto, Lukas; Badiani-Magnusson, Reena
    The surge in food prices following the 2021 economic rebound has become a significant concern for households, particularly low-income ones, in Bulgaria, Croatia, Poland, and Romania. Food price inflation, which surpasses general inflation rates, risks worsening poverty and food insecurity in these countries. This paper explores the distributional impacts of rising food prices and the effectiveness of government response measures. Low-income households, who allocate a larger share of their income to food, are disproportionately affected and are struggling to cope with unexpected expenses, leading to increased difficulties in accessing proper nutrition. Simulations indicate that rising food prices contribute to higher poverty rates and greater income inequality, especially among vulnerable populations. They also suggest that the main poverty-targeted social assistance schemes offer critical support for the extreme poor, but expanding both coverage and benefits is vital to shield all at-risk individuals. Targeted policies that balance immediate relief with long-term resilience-building are essential to addressing the challenges posed by escalating food prices.

    Disentangling the Key Economic Channels through Which Infrastructure Affects Jobs
    (Washington, DC: World Bank, 2025-04-03) Vagliasindi, Maria; Gorgulu, Nisan
    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.

    Short- and Long-Term Effects of United Nations Peace Operations
    (World Bank, 2008-01-30) Sambanis, Nicholas
    In an earlier study Doyle and Sambanis (2000) [Doyle, Michael W., and Nicholas Sambanis. 2000. "International Peacebuilding: A Theoretical and Quantitative Analysis." American Political Science Review 94(4):779–801.] showed that United Nations (UN) peace operations have made positive contributions to peacebuilding in the short term, helping parties implement peace agreements. But are the effects of UN peace operations lasting? Because the UN cannot fight wars, such operations should not be used to enforce a peace. Peacekeeping operations contribute more to the quality of the peace—that is, to securing more than the mere absence of war—than to its duration, because the effects of such operations dissipate over time. For peace to be self-sustaining, countries must develop institutions and policies that generate economic growth. UN peacebuilding lacks a strategy for fostering self-sustaining economic growth that could connect increased participation with sustainable peace. The international community would benefit from an evolution that uses economic reforms to plug the gap between peacekeeping and humanitarian assistance on the one hand and development on the other.

    Democratic Republic of the Congo
    (World Bank, Washington, DC, 2011-03-02) Gambino, Tony
    The Democratic Republic of the Congo (DRC) has been described by one senior African diplomat at the United Nations as a 'state in the making; it is not yet a state.' Further, this 'state in the making' also is a state that, with few exceptions, has been in decline since the early 1970s. The colonial era, from 1885 until 1958, was a period of nearly uninterrupted state construction; the hegemony of the Belgian colonial apparatus steadily deepened. In its final two years, the colonial edifice progressively lost control over civil society to a tumultuous and fragmented nationalist movement, which was unable to capture intact the colonial infrastructure. The result was five years of turbulent state deflation, generally known as the 'Congo crisis.' The Mobutu coup of 1965 inaugurated a new cycle, with eight years in which a rising tide of state ascendancy seemed to dominate the political process. After 1974 currents of decline again began to flow strongly, progressively eroding the superstructure of hegemony. The actual purpose of the Zairian government under Mobutu was not to fulfill basic state functions; rather, the government existed as a structure for individual enrichment and patronage. Officials at the highest levels stole large amounts of money, usually from mineral or customs revenues, sometimes through extremely straightforward strategies, such as literally pocketing gem diamonds and having them sold for personal gain in Antwerp or elsewhere.

    Conflict in Melanesia
    (World Bank, Washington, DC, 2010-11-02) Dinnen, Sinclair; Porter, Doug; Sage, Caroline
    This case study examines contemporary experiences of conflict in four contexts: Papua New Guinea, with particular reference to the island of Bougainville and the Highlands region; Solomon Islands; and Vanuatu. We find common themes in these experiences, despite the regions famous sociolinguistic diversity, fragmented geography and varied experience of globalization. Melanesia offers distinctive lessons about how conflict may be understood, promoted and avoided. The paper is organized in two broad parts. The first part is contextual. It provides a brief account of conflict and violence in social life before and after colonization. It then tracks, largely chronologically, through the local, national and transnational dimensions of contemporary conflict, how it was avoided, how it has changed, and how it has been managed in different contexts. Particular attention is given to global and regional influences, and to how governments, local people, and external security, development and commercial actors, have worked to mitigate and, at times, exacerbate conflict. The second part of the case study is more analytical. It steps back from the particulars to address themes and propositions in the overall conceptual framing of World Development Report (WDR) 2011 about the nature of conflict, and the underlying stresses and interests that may render it more likely. Part two draws lessons from the histories and contexts discussed in part one. The report organizes these around three themes that reflect views shared with us by people during consultations. The first highlights the need to recognize conflict as an inherent part of social change and thus the need to distinguish between socially generative social contest, and forms of conflict that are corrosive and destructive. The second examines how the ways people 'see' and understand the world directly shapes systems of regulation and 'the rules of the game' and thus directly affect responses to conflict. The third theme argues that capable and legitimate institutions to regulate social contest requires not just capable state institutions, but as much, relationships with local and international agents and organizations operating below and above the state.

    Partial Peace Rebel Groups Inside and Outside Civil War Ssettlements
    (Washington, DC: World Bank, 2008-03) Nilsson, Desirée
    Previous research proposes that peace is more likely to become durable if all rebel groups are included in the settlement reached. The argument implies that if actors are excluded and continue to pursue the military course, this could have a destabilizing effect on the actors that have signed an agreement. This article argues that all-inclusive peace deals - signed by the government and all rebel groups - are not the panacea for peace that many seem to believe. Given that the parties are strategic actors who are forward-looking when making their decisions, the signatories should anticipate that the excluded parties may continue to fight. Therefore, the risk of violent challenges from outside actors is likely to already be factored into the decision-making calculus when the signatories decide to reach a deal, and so does not affect their commitment to peace. Implications from this theoretical argument are tested using unique data on the conflict behavior of the government and each of the rebel groups in internal armed conflicts during the post-Cold War period. The results are well in line with the theoretical expectations and show that whether an agreement leaves out some actor does not affect whether the signatories stick to peace. The results demonstrate that even when excluded rebel groups engage in conflict, this does not affect the signatories' commitment to peace. Hence, the findings suggest that partial peace is possible.

    Breaking the Conflict Trap : Civil War and Development Policy
    (Washington, DC: World Bank and Oxford University Press, 2003) Collier, Paul; Elliott, V. L.; Hegre, Håvard; Hoeffler, Anke; Reynal-Querol, Marta; Sambanis, Nicholas
    Most wars are now civil wars. Even though international wars attract enormous global attention, they have become infrequent and brief. Civil wars usually attract less attention, but they have become increasingly common and typically go on for years. This report argues that civil war is now an important issue for development. War retards development, but conversely, development retards war. This double causation gives rise to virtuous and vicious circles. Where development succeeds, countries become progressively safer from violent conflict, making subsequent development easier. Where development fails, countries are at high risk of becoming caught in a conflict trap in which war wrecks the economy and increases the risk of further war. The global incidence of civil war is high because the international community has done little to avert it. Inertia is rooted in two beliefs: that we can safely 'let them fight it out among themselves' and that 'nothing can be done' because civil war is driven by ancestral ethnic and religious hatreds. The purpose of this report is to challenge these beliefs.

    Guide to the Debt Management Performance Assessment Tool
    (Washington, DC, 2008-02-05) World Bank
    The purpose of this document is to provide guidance and supplemental information to assist with country assessments of debt management performance, using the Debt Management Performance Assessment (DeMPA) tool. The DeMPA is a methodology used for assessing public debt management performance through a comprehensive set of 15 performance indicators spanning the full range of government Debt Management (DeM) functions. It is based on the principles set out in the International Monetary Fund (IMF) and World Bank guidelines for public debt management, initially published in 2001 and updated in 2003. It is modeled after the Public Expenditure and Financial Accountability (PEFA) framework for performance measurement of public financial management. The DeMPA has been designed to be a user-friendly tool to undertake an assessment of the strengths and weaknesses in government DeM practices. This guide provides additional background and supporting information so that a no specialist in the area of debt management may undertake a country assessment effectively. The guide can be used by assessors in preparing for and undertaking an assessment. It is particularly useful for understanding the rationale for the inclusion of the indicators, the scoring methodology, and the list of supporting documents or evidence required, and the questions that could be asked for the assessment.

    The Mexican Social Protection System in Health
    (World Bank, Washington DC, 2013-01) Bonilla-Chacín, M.E.; Aguilera, Nelly
    With a population of 113 million and a per-capita Gross Domestic Product, or GDP of US$10,064 (current U.S. dollars), Mexico is one of the largest and highest-income countries in Latin America and the Caribbean (LAC). The country has benefited from sustained economic growth during the last decade, which was temporarily interrupted by the financial and economic crisis. Real GDP is projected to grow 3.8 percent and 3.6 percent in 2012 and 2013, respectively (International Monetary Fund, or IMF 2012). Despite this growth, poverty in the country remains high; with half of the population living below the national poverty line. The country is also highly heterogeneous, with large socioeconomic differences across states and across urban and rural areas. In 2010, while the extreme poverty ratio in the Federal District and the states of Colima and Nuevo Leon was below 3 percent, in Chiapas, Guerrero, and Oaxaca it was 25 percent or higher. These large regional differences are also found in other indicators of well-being, such as years of schooling, housing conditions, and access to social services. This case study assesses key features and achievements of the Social Protection System in Health (Sistema de Proteccion Social en Salud) in Mexico, and particularly of its main pillar, Popular Health Insurance (Seguro Popular, PHI). It analyzes the contribution of this policy to the establishment and implementation of universal health coverage in Mexico. In 2003, with the reform of the General Health Law, the PHI was institutionalized as a subsidized health insurance scheme open to the population not covered by the social security schemes. Today, the PHI covers all of its intended affiliates, about 52 million people

    Classroom Assessment to Support Foundational Literacy
    (Washington, DC: World Bank, 2025-03-21) Luna-Bazaldua, Diego; Levin, Victoria; Liberman, Julia; Gala, Priyal Mukesh
    This document focuses primarily on how classroom assessment activities can measure students’ literacy skills as they progress along a learning trajectory towards reading fluently and with comprehension by the end of primary school grades. The document addresses considerations regarding the design and implementation of early grade reading classroom assessment, provides examples of assessment activities from a variety of countries and contexts, and discusses the importance of incorporating classroom assessment practices into teacher training and professional development opportunities for teachers. The structure of the document is as follows. The first section presents definitions and addresses basic questions on classroom assessment. Section 2 covers the intersection between assessment and early grade reading by discussing how learning assessment can measure early grade reading skills following the reading learning trajectory. Section 3 compares some of the most common early grade literacy assessment tools with respect to the early grade reading skills and developmental phases. Section 4 of the document addresses teacher training considerations in developing, scoring, and using early grade reading assessment. Additional issues in assessing reading skills in the classroom and using assessment results to improve teaching and learning are reviewed in section 5. Throughout the document, country cases are presented to demonstrate how assessment activities can be implemented in the classroom in different contexts.

    Europe and Central Asia Economic Update, Fall 2024: Better Education for Stronger Growth
    (Washington, DC: World Bank, 2024-10-17) Izvorski, Ivailo; Kasyanenko, Sergiy; Lokshin, Michael M.; Torre, Iván
    Economic growth in Europe and Central Asia (ECA) is likely to moderate from 3.5 percent in 2023 to 3.3 percent this year. This is significantly weaker than the 4.1 percent average growth in 2000-19. Growth this year is driven by expansionary fiscal policies and strong private consumption. External demand is less favorable because of weak economic expansion in major trading partners, like the European Union. Growth is likely to slow further in 2025, mostly because of the easing of expansion in the Russian Federation and Turkiye. This Europe and Central Asia Economic Update calls for a major overhaul of education systems across the region, particularly higher education, to unleash the talent needed to reinvigorate growth and boost convergence with high-income countries. Universities in the region suffer from poor management, outdated curricula, and inadequate funding and infrastructure. A mismatch between graduates' skills and the skills employers are seeking leads to wasted potential and contributes to the region's brain drain. Reversing the decline in the quality of education will require prioritizing improvements in teacher training, updated curricula, and investment in educational infrastructure. In higher education, reforms are needed to consolidate university systems, integrate them with research centers, and provide reskilling opportunities for adult workers.

    World Development Report 2014
    (Washington, DC, 2013-10-06) World Bank
    The past 25 years have witnessed unprecedented changes around the world—many of them for the better. Across the continents, many countries have embarked on a path of international integration, economic reform, technological modernization, and democratic participation. As a result, economies that had been stagnant for decades are growing, people whose families had suffered deprivation for generations are escaping poverty, and hundreds of millions are enjoying the benefits of improved living standards and scientific and cultural sharing across nations. As the world changes, a host of opportunities arise constantly. With them, however, appear old and new risks, from the possibility of job loss and disease to the potential for social unrest and environmental damage. If ignored, these risks can turn into crises that reverse hard-won gains and endanger the social and economic reforms that produced these gains. The World Development Report 2014 (WDR 2014), Risk and Opportunity: Managing Risk for Development, contends that the solution is not to reject change in order to avoid risk but to prepare for the opportunities and risks that change entails. Managing risks responsibly and effectively has the potential to bring about security and a means of progress for people in developing countries and beyond. Although individuals’ own efforts, initiative, and responsibility are essential for managing risk, their success will be limited without a supportive social environment—especially when risks are large or systemic in nature. The WDR 2014 argues that people can successfully confront risks that are beyond their means by sharing their risk management with others. This can be done through naturally occurring social and economic systems that enable people to overcome the obstacles that individuals and groups face, including lack of resources and information, cognitive and behavioral failures, missing markets and public goods, and social externalities and exclusion. These systems—from the household and the community to the state and the international community—have the potential to support people’s risk management in different yet complementary ways. The Report focuses on some of the most pressing questions policy makers are asking. What role should the state take in helping people manage risks? When should this role consist of direct interventions, and when should it consist of providing an enabling environment? How can governments improve their own risk management, and what happens when they fail or lack capacity, as in many fragile and conflict-affected states? Through what mechanisms can risk management be mainstreamed into the development agenda? And how can collective action failures to manage systemic risks be addressed, especially those with irreversible consequences? The WDR 2014 provides policy makers with insights and recommendations to address these difficult questions. It should serve to guide the dialogue, operations, and contributions from key development actors—from civil society and national governments to the donor community and international development organizations.
