Abstract
This paper finds large effects on the earnings of participants from a randomized intervention that gave psychosocial stimulation to stunted Jamaican toddlers living in poverty. The intervention consisted of one-hour weekly visits from community Jamaican health workers over a 2-year period that taught parenting skills and encouraged mothers to interact and play with their children in ways that would develop their children's cognitive and personality skills. The authors re-interviewed the study participants 20 years after the intervention. Stimulation increased the average earnings of participants by 42 percent. Treatment group earnings caught up to the earnings of a matched non-stunted comparison group. These findings show that psychosocial stimulation early in childhood in disadvantaged settings can have substantial effects on labor market outcomes and reduce later life inequality.

Publication The Economic Value of Weather Forecasts: A Quantitative Systematic Literature Review(Washington, DC: World Bank, 2025-09-10)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.Publication The Macroeconomic Implications of Climate Change Impacts and Adaptation Options(Washington, DC: World Bank, 2025-05-29)Estimating the macroeconomic implications of climate change impacts and adaptation options is a topic of intense research. This paper presents a framework in the World Bank's macrostructural model to assess climate-related damages. This approach has been used in many Country Climate and Development Reports, a World Bank diagnostic that identifies priorities to ensure continued development in spite of climate change and climate policy objectives. The methodology captures a set of impact channels through which climate change affects the economy by (1) connecting a set of biophysical models to the macroeconomic model and (2) exploring a set of development and climate scenarios. The paper summarizes the results for five countries, highlighting the sources and magnitudes of their vulnerability --- with estimated gross domestic product losses in 2050 exceeding 10 percent of gross domestic product in some countries and scenarios, although only a small set of impact channels is included. The paper also presents estimates of the macroeconomic gains from sector-level adaptation interventions, considering their upfront costs and avoided climate impacts and finding significant net gross domestic product gains from adaptation opportunities identified in the Country Climate and Development Reports. Finally, the paper discusses the limits of current modeling approaches, and their complementarity with empirical approaches based on historical data series. The integrated modeling approach proposed in this paper can inform policymakers as they make proactive decisions on climate change adaptation and resilience.Publication Labor Demand in the Age of Generative AI: Early Evidence from the U.S. Job Posting Data(Washington, DC: World Bank, 2025-11-18)This paper examines the causal impact of generative artificial intelligence on U.S. labor demand using online job posting data. Exploiting ChatGPT’s release in November 2022 as an exogenous shock, the paper applies difference-in-differences and event study designs to estimate the job displacement effects of generative artificial intelligence. The identification strategy compares labor demand for occupations with high versus low artificial intelligence substitution vulnerability following ChatGPT’s launch, conditioning on similar generative artificial intelligence exposure levels to isolate substitution effects from complementary uses. The analysis uses 285 million job postings collected by Lightcast from the first quarter of 2018 to the second quarter of 2025Q2. The findings show that the number of postings for occupations with above-median artificial intelligence substitution scores fell by an average of 12 percent relative to those with below-median scores. The effect increased from 6 percent in the first year after the launch to 18 percent by the third year. Losses were particularly acute for entry-level positions that require neither advanced degrees (18 percent) nor extensive experience (20 percent), as well as those in administrative support (40 percent) and professional services (30 percent). Although generative artificial intelligence generates new occupations and enhances productivity, which may increase labor demand, early evidence suggests that some occupations may be less likely to be complemented by generative artificial intelligence than others.Publication The Lasting Effects of Working while in School(Washington, DC: World Bank, 2025-08-18)This paper provides the first experimental evidence on the long-term effects of work-study programs, leveraging a randomized lottery design from a national program in Uruguay. Participation leads to a persistent 11 percent increase in formal labor earnings, observable seven years after the program. Effects are stronger for youth who participate during pivotal educational transitions and are larger for vulnerable youth and men, while remaining positive for women and non-vulnerable youth. The program is highly cost-effective, with average impacts exceeding those of job training programs and comparable to early childhood investments.Publication It’s Not (Just) the Tariffs: Rethinking Non-Tariff Measures in a Fragmented Global Economy(Washington, DC: World Bank, 2025-10-22)As tariffs have declined, non-tariff measures (NTMs) have become central to trade policy, especially in high-income countries and regulated sectors like food and green technologies. Although NTMs may serve legitimate goals, they could also sort countries and firms into or out of markets based on compliance capacity and differences in product mix. Documenting recent advances in the estimation of ad valorem equivalents (AVEs), this paper uncovers new patterns of use and exposure of NTMs. High-income countries rely more heavily on NTMs relative to tariffs, while low- and middle-income countries face steeper AVEs on their exports. Firm-level evidence shows that NTMs disproportionately affect smaller firms, leading to market exit and concentration. Poorly designed NTMs can harm productivity and welfare, while coordinated, capacity-aware use can deliver inclusive outcomes. Policy design, transparency, and diagnostics must evolve to reflect the growing role—and risks—of NTMs in a fragmented global trade landscape.

Publication Impacts of Interventions during Early Childhood on Later Outcomes(World Bank, Washington, DC, 2015-03-31)In an effort to bridge the evidence gap, the Independent Evaluation Group (IEG) prepared a systematic review that gathers and analyzes the available impact evaluation evidence in developing countries from 1990 to 2013 on whether early childhood interventions shape future outcomes. Its purpose is not to supplant existing evidence but rather to help practitioners understand how evidence from impact evaluations supports or challenges beliefs about interventions and can be used to inform development policy. This review aims to answer two questions: (1) What is the evidence of attributable effects on outcomes in primary school and beyond from interventions in low- and middle-income countries that occur during the early childhood period? and (2) How do the post-early childhood effects of early childhood interventions vary by socioeconomic status, gender, age at intervention, and age at evaluation, particularly during the first 1,000 days from conception to the childs second birthday and from age three to primary school enrollment at age five to six? This report reviews all interventions from developing countries that occur during early childhood for which impact evaluation estimates exist for effects observed at primary school age and older. From an initial search of thousands of studies, the search process which included database searches, hand searches, and snowballing identified more than 500 relevant impact evaluations written from 1990 to 2015. This review covers six areas or domains of human development: physical development, cognitive development, language development, socio-emotional development, schooling outcomes, and employment and labor market outcomes. These domains are commonly included in evaluations of early interventions targeting poor children because they are negatively affected by early poverty, can benefit from early intervention, and are important for overall well-being or adult productivity. Some outcomes can be measured repeatedly starting from early childhood (i.e., height and weight) while others are only measurable later in life (i.e., cognition, schooling, and employment and labor market status).Publication No Small Matter : The Impact of Poverty, Shocks, and Human Capital Investments in Early Childhood Development(World Bank, 2011-02-24)The relative lack of attention to early childhood development in many developing countries remains a puzzle, and an opportunity. There is increasing evidence that investments in the nutritional, cognitive, and socio-emotional development of young children have high payoffs. Researchers and development practitioners are building on this evidence to raise the topic's profile and bring it to the attention of decision makers. This volume is an important contribution to these efforts. It thoroughly and carefully reviews the most recent empirical literature linking early childhood development outcomes, poverty, and shocks. In doing so, it brings an added perspective to the debate and makes the case that investments in the first years of life have the potential to be a critical component of poverty reduction strategies. The volume also goes beyond simply documenting the consequences of insufficient or inadequate focus on early childhood and identifies the range of policy options available to policy makers. The Human Development Perspectives series seeks to present thorough research findings on issues of critical strategic importance for developing countries. At its core is the perspective that investments in human capital are an essential aspect of efforts to promote global development and eradicate poverty. This volume makes it convincingly clear that investing in and protecting the human capital of young children is no small matter.Publication Children and Youth in Crisis : Protecting and Promoting Human Development in Times of Economic Shocks(Washington, DC: World Bank, 2012)Motivated by the need to understand how crises affect human development in diverse segments of the population, this book explores how individuals and households cope with the changes and stresses induced by economic crises. It examines how these impacts and coping mechanisms differ across cultural and institutional contexts and looks at how best to protect the most vulnerable from lasting harm and the degradation of human capital. Financial crises, at both the global and the national level, are ubiquitous. Reinhart and Rogoff (2009) provide the invaluable lesson that over the past 800 years a major crisis has happened roughly once every 20 years. This pattern raises concern about the human impacts of crises, especially among more vulnerable people in developing countries. During the most recent global financial crisis, international organizations, bilateral development agencies, and civil society organizations all expressed concern about the ongoing 'human crisis.' The global community has become alarmed that the crisis could reverse recent progress in poverty reduction and the achievement of the Millennium Development Goals. Human development is at the core of economic development. Human capital accumulation at all stages from the antenatal environment through early childhood and adolescence helps facilitate the transition to a healthy and productive adulthood and break the intergenerational transmission of poverty. Shortfalls or setbacks at any stage of the life course may have severe consequences for individual development as well as for the growth and development of successful communities. The work presented in this volume deepens our understanding of how shocks affect children and youth in two ways. First, the authors aggregate the evidence on various developmental outcomes across developmental stages from conception to adulthood. Second, the authors show that the impact of crises will differ according to the social and environmental contexts in which the child or young person grows and that shocks can in turn affect those contexts. The authors hope to understand the short- and long-term impacts of crises, and whether we can identify particular protective factors that support children's recovery from the worst ravages of the crisis. The focus on transmission mechanisms, the pathways of influence, leads to a set of broad policy recommendations for enhancing both protection and recovery.Publication The Impact of Expanding Access to Early Childhood Services in Rural Indonesia(World Bank, Washington, DC, 2015-07)This paper uses three waves of longitudinal data to examine the impact of expanding access to preschool services in rural areas of Indonesia on two cohorts of children. One cohort was children aged 4 at the start of the project and was immediately eligible for project-provided services when they began operation in 2009. The other cohort was children aged 1 at the start of the project and became eligible for project-provided services two years later. The paper presents intent-to-treat estimates of impact in the short term (first year of the project) and medium term (three years after the project started), using experimental and quasi-experimental methods. For the cohort of 4-year-olds, while the magnitude of the enrollment impact is similar across children from different backgrounds, the impact on child outcomes is larger for children from more disadvantaged backgrounds in the short and medium terms. However, for this cohort of children, it seems that project-provided playgroups encouraged substitution away from existing kindergartens, suggesting that future interventions should incorporate such possibilities into their design. For the average child in the younger cohort, the project led to improvements in physical health and well-being as well as language and cognitive development. For this cohort, there is little evidence of differential impact. This can be explained by the fact that children who enrolled soon after the centers opened (the older cohort) were generally poorer, compared with children who enrolled later (the younger cohort). This may be because of fee increases in project centers as project funding ended.Publication Developing Social-Emotional Skills for the Labor Market : The PRACTICE Model(World Bank Group, Washington, DC, 2014-11)Although there is a general agreement in the literature of the importance of social-emotional skills for labor market success, there is little consensus on the specific skills that should be acquired or how and when to teach them. The psychology, economics, policy research, and program implementation literatures all touch on these issues, but they are not sufficiently integrated to provide policy direction. The objective of this paper is to provide a coherent framework and related policies and programs that bridge the psychology, economics, and education literature, specifically that related to skills employers value, non-cognitive skills that predict positive labor market outcomes, and skills targeted by psycho-educational prevention and intervention programs. The paper uses as its base a list of social-emotional skills that employers value, classifies these into eight subgroups (summarized by PRACTICE), then uses the psychology literature -- drawing from the concepts of psycho-social and neuro-biological readiness and age-appropriate contexts -- to map the age and context in which each skill subset is developed. The paper uses examples of successful interventions to illustrate the pedagogical process. The paper concludes that the social-emotional skills employers value can be effectively taught when aligned with the optimal stage for each skill development, middle childhood is the optimal stage for development of PRACTICE skills, and a broad international evidence base on effective program interventions at the right stage can guide policy makers to incorporate social-emotional learning into their school curriculum.

Publication Digital Africa(Washington, DC: World Bank, 2023-03-13)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.Publication Lebanon Economic Monitor, Fall 2022(Washington, DC, 2022-11)The economy continues to contract, albeit at a somewhat slower pace. Public finances improved in 2021, but only because spending collapsed faster than revenue generation. Testament to the continued atrophy of Lebanon’s economy, the Lebanese Pound continues to depreciate sharply. The sharp deterioration in the currency continues to drive surging inflation, in triple digits since July 2020, impacting the poor and vulnerable the most. An unprecedented institutional vacuum will likely further delay any agreement on crisis resolution and much needed reforms; this includes prior actions as part of the April 2022 International Monetary Fund (IMF) staff-level agreement (SLA). Divergent views among key stakeholders on how to distribute the financial losses remains the main bottleneck for reaching an agreement on a comprehensive reform agenda. Lebanon needs to urgently adopt a domestic, equitable, and comprehensive solution that is predicated on: (i) addressing upfront the balance sheet impairments, (ii) restoring liquidity, and (iii) adhering to sound global practices of bail-in solutions based on a hierarchy of creditors (starting with banks’ shareholders) that protects small depositors.Publication Argentina Country Climate and Development Report(World Bank, Washington, DC, 2022-11)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.Publication World Development Report 2006(Washington, DC, 2005)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.Publication Classroom Assessment to Support Foundational Literacy(Washington, DC: World Bank, 2025-03-21)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.
