Abstract
Scaling up early childhood development services has the potential to increase children's cognitive and socio-emotional development and promote school readiness in a large segment of the population. This study used a randomized controlled trial approach to evaluate three scaled-up programs designed to widen access to early childhood development services: formal preschools, community preschools, and home-based services. The impacts of all three programs fell short of expectations because of two key flaws in how they were scaled up. First, implementation did not receive due attention; as a result, school facilities were not completed as planned, community-based programs were not always established, and low, irregular stipends created difficulties in hiring and retaining teachers. Second, the services that were available were not promoted and thus not used as widely as anticipated. The results imply that the quality of programs supplied is critical, as is attention to the demand side of the problem. The finding that these programs fell short of expectations does not mean that interventions such as these are ineffective. Rather, it indicates that quality and demand require careful attention in attempts to scale up early childhood development interventions, and any problems should be addressed prior to evaluating effectiveness.

    Global Poverty Revisited Using 2021 PPPs and New Data on Consumption
    (Washington, DC: World Bank, 2025-06-05) Foster, Elizabeth; Jolliffe, Dean Mitchell; Lara Ibarra, Gabriel; 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.

    The Economic Value of Weather Forecasts: A Quantitative Systematic Literature Review
    (Washington, DC: World Bank, 2025-09-10) Farkas, Hannah; Linsenmeier, Manuel; Talevi, Marta; Avner, Paolo; Jafino, Bramka Arga; Sidibe, Moussa
    This study systematically reviews the literature that quantifies the economic benefits of weather observations and forecasts in four weather-dependent economic sectors: agriculture, energy, transport, and disaster-risk management. The review covers 175 peer-reviewed journal articles and 15 policy reports. Findings show that the literature is concentrated in high-income countries and most studies use theoretical models, followed by observational and then experimental research designs. Forecast horizons studied, meteorological variables and services, and monetization techniques vary markedly by sector. Estimated benefits even within specific subsectors span several orders of magnitude and broad uncertainty ranges. An econometric meta-analysis suggests that theoretical studies and studies in richer countries tend to report significantly larger values. Barriers that hinder value realization are identified on both the provider and user sides, with inadequate relevance, weak dissemination, and limited ability to act recurring across sectors. Policy reports rely heavily on back-of-the-envelope or recursive benefit-transfer estimates, rather than on the methods and results of the peer-reviewed literature, revealing a science-to-policy gap. These findings suggest substantial socioeconomic potential of hydrometeorological services around the world, but also knowledge gaps that require more valuation studies focusing on low- and middle-income countries, addressing provider- and user-side barriers and employing rigorous empirical valuation methods to complement and validate theoretical models.

    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.

    Geopolitical Risks and Trade
    (Washington, DC: World Bank, 2025-09-23) Mulabdic, Alen; Yotov, Yoto V.
    This paper studies the impact of geopolitical risks on international trade, using the Geopolitical Risk (GPR) index of Caldara and Iacoviello (2022) and an empirical gravity model. The impact of spikes in geopolitical risk on trade is negative, strong, and heterogeneous across sectors. The findings show that increases in geopolitical risk reduce trade by about 30 to 40 percent. These effects are equivalent to an increase of global tariffs of up to 14 percent. Services trade is most vulnerable to geopolitical risks, followed by agriculture, and the impact on manufacturing trade is moderate. These negative effects are partially mitigated by cultural and geographic proximity, as well as by the presence of trade agreements.

    Intelligence, Personality, and Creativity : Unleashing the Power of Intelligence and Personality Traits to Build a Creative and Innovative Economy
    (World Bank, Washington, DC, 2014-11-04) King, Elizabeth; Rogers, Halsey
    Cognitive ability, as measured by IQ and background factors such as socioeconomic status and demographics have historically been seen as the principal determinants of a student s academic success. However, a growing body of research from psychology, education, behavioral economics and neuroscience is showing that personality traits also predict academic and work performance. This change in paradigm suggests that education systems face a more complex challenge than traditionally recognized: to work not only with the different types of intelligence possessed by students but also with their different personality traits in order to produce academic success measured by cognitive and non-cognitive skills. This paper reviews the research findings from the different literatures (psychology, education, behavioral economics, and neuroscience) that relate to these questions. Several good reviews summarize the findings on aspects of these questions, but rarely address all of the questions above. In particular, those reviews do not shed light on how education can improve both cognitive and non-cognitive skills and how such skills promote creativity and labor market outcomes. The scientific literatures on human intelligence and personality are large, but our focus is on the subset of research findings that relate intelligence and personality to academic performance. Likewise, the literature on creativity, innovation, and productivity is extensive, but our focus will be on the research findings that relate academic performance to creativity and, ultimately, to productivity in the workplace.

    Investing in Young Children : An Early Childhood Development Guide for Policy Dialogue and Project Preparation
    (World Bank, 2011) Naudeau, Sophie; Kataoka, Naoko; Valerio, Alexandria; Neuman, Michelle J.; Elder, Leslie Kennedy
    Investing in young children is the responsible thing to do. All children deserve a chance to grow into healthy, educated, and competent people, no matter where and when they were born. While parents bear most of the responsibility for raising their children, especially in the early years of life, governments also have an important role during this critical time of human capital accumulation. For example, governments can ensure that all expectant mothers and young children have access to quality health services and nutrition. They can support parents and other caregivers in providing a positive and stimulating environment for children from birth on by promoting parenting information programs, investing in direct services such as home-based visits, funding daycare centers and preschools, or providing financial incentives to access good quality programs for infants and children. This Early Childhood Development (ECD) guide presents lessons and experiences that have been useful in informing the policy debate about ECD interventions and the design of such programs across the world. Whether the user of this guide is at the initial stage of deciding whether to expand an ECD portfolio or already in the program design stage, the content offers a range of evidence- based options to inform policy and investment choices.

    Toward an Equal Start
    (World Bank, Washington, DC, 2012-06-04) World Bank
    Early childhood development programs are particularly beneficial to children from disadvantaged backgrounds. Effective investments in this area have the potential to reduce inequalities perpetuated by poverty, poor nutrition, and restricted learning opportunities. This report explores the gaps in early education and care experienced by Roma children between the ages of 3 and 6 in Eastern Europe, and looks at measures to close those gaps. Many Roma children lack a strong early learning and care support mechanism at home. The vast majority of Roma children grow up in poverty and many regularly go hungry. Their parents have minimal levels of education. This creates multiple disadvantages from malnutrition to limited early learning stimulation. The report points to four main policy measures to increase pre-school enrollment and improve early learning at home: (1) better inform parents on the benefits of preschool for children's later life outcomes; (2) promote inclusive pre-schools by reaching out to parents and by involving them more directly in pre-school with the help of Roma teaching assistants; (3) remove cost barriers possibly coupled with regular attendance subsidies. In addition: (4) support parenting at home. These conclusions follow from the finding that the vast majority of Roma parents wish their children to complete secondary education, but that many also stated a desire to raise children at home in their early years when asked why they did not enroll their children in preschool. The report also calls for systematic piloting with variations of different programs, and implementing randomized impact evaluations. Findings from impact evaluations can build public support for scale-up of proven programs. Finally, the report points out that ensuring that poor Roma and non-Roma children alike receive an equal start in life by investing in early childhood development is essential to break the cycle of intergenerational poverty and is also smart economics.

    Examining Early Child Development in Low-Income Countries
    (World Bank, Washington, DC, 2009-04-03) Fernald, Lia C. H.; Kariger, Patricia; Engle, Patrice; Raikes, Abbie
    The primary purpose of this toolkit is to provide a resource for researchers from various disciplines interested in planning and evaluating programs or interventions aimed at improving the health and development of infants and young children. The toolkit aims to: provide an overview of issues affecting early development and its measurement; discuss the types of tests typically used with children under five years; provide guidelines for selecting and adapting tests for use in developing countries, and make recommendations for planning successful assessment strategies. The toolkit focuses on children who have not yet entered school, and are thus under six years old. The primary reason we are focusing on this age group is that during the first five years of life, children's language, early understanding of mathematics and reading, and self-control emerge. The extent to which children master these skills during this critical period has implications for success in school (Lerner, 1998), and thus we wanted to focus on children in this pre-school period. The toolkit is essential at this time for the following reasons: children in developing countries are growing up at a disadvantage; assessments of children must expand to include a wider range of outcomes; and no such toolkit exists as present.

    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.

    Argentina Country Climate and Development Report
    (World Bank, Washington, DC, 2022-11) World Bank Group
    The Argentina Country Climate and Development Report (CCDR) explores opportunities and identifies trade-offs for aligning Argentina’s growth and poverty reduction policies with its commitments on, and its ability to withstand, climate change. It assesses how the country can: reduce its vulnerability to climate shocks through targeted public and private investments and adequation of social protection. The report also shows how Argentina can seize the benefits of a global decarbonization path to sustain a more robust economic growth through further development of Argentina’s potential for renewable energy, energy efficiency actions, the lithium value chain, as well as climate-smart agriculture (and land use) options. Given Argentina’s context, this CCDR focuses on win-win policies and investments, which have large co-benefits or can contribute to raising the country’s growth while helping to adapt the economy, also considering how human capital actions can accompany a just transition.

    World Development Report 2006
    (Washington, DC, 2005) World Bank
    This year’s Word Development Report (WDR), the twenty-eighth, looks at the role of equity in the development process. It defines equity in terms of two basic principles. The first is equal opportunities: that a person’s chances in life should be determined by his or her talents and efforts, rather than by pre-determined circumstances such as race, gender, social or family background. The second principle is the avoidance of extreme deprivation in outcomes, particularly in health, education and consumption levels. This principle thus includes the objective of poverty reduction. The report’s main message is that, in the long run, the pursuit of equity and the pursuit of economic prosperity are complementary. In addition to detailed chapters exploring these and related issues, the Report contains selected data from the World Development Indicators 2005‹an appendix of economic and social data for over 200 countries. This Report offers practical insights for policymakers, executives, scholars, and all those with an interest in economic development.

    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.

    Morocco Economic Update, Winter 2025
    (Washington, DC: World Bank, 2025-04-03) World Bank
    Despite the drought causing a modest deceleration of overall GDP growth to 3.2 percent, the Moroccan economy has exhibited some encouraging trends in 2024. Non-agricultural growth has accelerated to an estimated 3.8 percent, driven by a revitalized industrial sector and a rebound in gross capital formation. Inflation has dropped below 1 percent, allowing Bank al-Maghrib to begin easing its monetary policy. While rural labor markets remain depressed, the economy has added close to 162,000 jobs in urban areas. Morocco’s external position remains strong overall, with a moderate current account deficit largely financed by growing foreign direct investment inflows, underpinned by solid investor confidence indicators. Despite significant spending pressures, the debt-to-GDP ratio is slowly declining.
