Abstract
This paper experimentally examines the impacts of a large-scale government program that increased the supply and quality of community preschools in rural Cambodia. The construction of new preschool facilities was paired with two demand-side interventions designed to stimulate additional enrollment into preschools. The newly constructed preschools caused an increase in enrollment rates but the demand-side interventions did not. One year after the program started, the paper finds small and significant impacts on cognitive (0.04 standard deviations) and socio-emotional development (0.09 standard deviations). The analysis shows that the cognitive impacts are driven by children from the wealthiest quartile, while the program had limited impacts on children from the poorest families. The effects on cognitive development increased after two years for the wealthiest (the cognitive gap widened) while the effects on socio-emotional development faded out across the board. Using detailed classroom surveys and in-class observations, the paper shows that the program had large impacts on the quality of preschool infrastructure and materials but only limited impacts the quality of educational processes -- the results therefore suggest that further improvement of those processes might be needed to foster the development of disadvantaged children.

Publication Geopolitics and the World Trading System(Washington, DC: World Bank, 2024-12-23)Until the beginning of this century, the GATT/WTO system worked. Economic research provided a compelling explanation. It showed that if governments maximize the well-being of their own countries broadly defined, GATT/WTO principles would facilitate mutually beneficial cooperation over their trade policy choices. Now heightened geopolitical rivalry seems to have undermined the WTO. A simple transposition of the previous rationalization suggests that geopolitics and trade cooperation are not compatible. The paper shows that this is only true if rivalry eclipses any consideration of own-country well-being. In all other circumstances, there are gains from trade cooperation even with geopolitics. Furthermore, the WTO’s relevance is in question only if it adheres too rigidly to its existing rules and norms. Through measured adaptation to the geopolitical imperative, the WTO can continue to thrive as a forum for multilateral trade cooperation in the age of geopolitics.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 Global Poverty Revisited Using 2021 PPPs and New Data on Consumption(Washington, DC: World Bank, 2025-06-05)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.Publication From Patriarchy to Policy(Washington, DC: World Bank, 2025-05-29)Legal institutions play an important role in shaping gender equality in economic domains, from inheritance to labor markets. But where do gender equal laws come from? Using cross-country data on social norms and legal equality, this paper investigates the socio-cultural roots of gender inequity in the legal system and its implications for female labor force participation. To identify the impact of social norms, the analysis uses an empirical strategy that exploits pre-modern differences in ancestral patriarchal culture as an instrument for present-day gender norms. The findings show that ancestral patriarchal culture is a strong predictor of contemporary norms, and conservative social norms are associated with more gender inequality in the de jure legal framework, the de facto implementation of laws, and the labor market. The paper presents evidence for a political selection mechanism linking norms to laws: countries with more conservative norms elect political leaders who are more hostile to gender equality, who then pass less progressive legislation. The results highlight the cultural roots and political drivers of legalized gender inequality.Publication Global Socio-economic Resilience to Natural Disasters(Washington, DC: World Bank, 2025-05-22)Most disaster risk assessments use damages to physical assets as their central metric, often neglecting distributional impacts and the coping and recovery capacity of affected people. To address this shortcoming, the concepts of well-being losses and socio-economic resilience—the ability to experience asset losses without a decline in well-being—have been proposed. This paper uses microsimulations to produce a global estimate of well-being losses from, and socio-economic resilience to, natural disasters, covering 132 countries. On average, each $1 in disaster-related asset losses results in well-being losses equivalent to a $2 uniform national drop in consumption, with significant variation within and across countries. The poorest income quintile within each country incurs only 9% of national asset losses but accounts for 33% of well-being losses. Compared to high-income countries, low-income countries experience 67% greater well-being losses per dollar of asset losses and require 56% more time to recover. Socio-economic resilience is uncorrelated with exposure or vulnerability to natural hazards. However, a 10 percent increase in GDP per capita is associated with a 0.9 percentage point gain in resilience, but this benefit arises indirectly—such as through higher rate of formal employment, better financial inclusion, and broader social protection coverage—rather than from higher income itself. This paper assess ten policy options and finds that socio-economic and financial interventions (such as insurance and social protection) can effectively complement asset-focused measures (e.g., construction standards) and that interventions targeting low-income populations usually have higher returns in terms of avoided well-being losses per dollar invested.

Publication Cambodia(World Bank, Washington, DC, 2020-05)Early childhood is a critical period for growth and development. Research shows that giving young children enough nurturing and stimulating experiences during these early years not only improves their chances of success in school but can also help them succeed and be more productive later in life. Although access to preschool has increased substantially in recent years, in many low-income communities’ children don’t receive any educational services before they start primary school. In some cases, parents aren’t aware of the value of early education and might not take advantage of opportunities to enroll their children in preschool, even when services are available.Publication Impact Evaluation of Three Types of Early Childhood Development Interventions in Cambodia(World Bank, Washington, DC, 2013-07)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.Publication Preschool and Parental Response in a Second Best World(University of Wisconsin Press, 2019-03-31)Interventions targeting early childhood hold promise for reducing the intergenerational transmission of poverty. Results from a randomized evaluation of a preschool construction program in Cambodia suggest caution. Overall impacts on early childhood outcomes are small and insignificant. Impacts on cognition are negative for the cohort with highest program exposure, with the largest negative effects among children of poorer and less educated parents. The results are explained by substitution from primary to preschool and differences in demand responses to preschools between more and less educated parents. Context, program specifics, and behavioral responses can hence lead to perverse effects of well-intentioned interventions.Publication Joint Effects of Parenting and Nutrition Status on Child Development(World Bank, Washington, DC, 2018-07)Substantial work has demonstrated that early nutrition and home environments, including the degree to which children receive cognitive stimulation and emotional support from parents, play a profound role in influencing early childhood development. Yet, less work has documented the joint influences of parenting and nutrition status on child development among children in the preschool years living in low-income countries. Using panel data on parenting, nutrition status, and early developmental outcomes of about 7,000 Cambodian preschool-age children, this paper demonstrates that inequities in early development associated with family wealth are evident at the start of preschool and increase over time. A significant share of these inequalities can be explained by differences in parental stimulation and early nutrition status. Better educated parents engage in better parental activities that stimulate children's development. However, the positive association between parental activities and child outcomes is particularly strong for non-stunted children, and parental activities can only explain about 8-14 percent of the cognitive gap between the lowest and highest wealth quintiles. The results highlight the need for integrated interventions that address both parenting and early nutrition, also suggesting that parenting interventions for the most disadvantaged families should be carefully designed and evaluated to ensure maximum effectiveness.Publication Improving Preschool Provision and Encouraging Demand(World Bank, Washington, DC, 2020-10)This paper studies the impact of a preschool construction program and of two demand-side interventions in Cambodia. Within this context where other preschools are available, impacts are likely to differ between children who would have been enrolled in a preexisting preschool and those who would have stayed at home, with larger expected gains for the latter. The construction program caused enrollment to increase but demand-side interventions did not. After one year, the study measures intent-to-treat impacts on cognitive (0.04 standard deviations) and socio-emotional development (0.07 SD). The analysis also shows that the effect on children who would have stayed at home can be bounded (between 0.14 SD and 0.45 SD). With further assumptions these bounds can be tightened (0.14 SD – 0.35 SD) and under heavier assumptions, the study estimates this effect to be 0.19 SD, while the effect on children who would have benefited from another preschool is small and insignificant. These results are consistent with measures of preschool quality which imply that the newly constructed schooled only significantly improved infrastructure quality and not process quality. After two years of program implementation, most impacts become insignificant suggesting that the advantage provided by preschool quickly vanished, specifically once children enrolled in primary school.

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 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.Publication Unlocking Blue Carbon Development(Washington, DC: World Bank, 2023-09-11)The purpose of this paper is to provide a practical framework to guide governments in catalyzing and scaling up public and private investment in Blue Carbon as part of their blue economy development. It does this by describing in detail a Blue Carbon Readiness Framework, a step-by-step, well-illustrated guide with simple checklists. Client countries can use the illustrations and checklists to determine their readiness to catalyze and scale up investment in blue carbon credit finance. The Blue Carbon Readiness Framework consists of three pillars: 1. Data and Analytics; 2. Policy and Institutions; 3. Finance.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.Publication World Development Report 2011(World Bank, 2011)The 2011 World development report looks across disciplines and experiences drawn from around the world to offer some ideas and practical recommendations on how to move beyond conflict and fragility and secure development. The key messages are important for all countries-low, middle, and high income-as well as for regional and global institutions: first, institutional legitimacy is the key to stability. When state institutions do not adequately protect citizens, guard against corruption, or provide access to justice; when markets do not provide job opportunities; or when communities have lost social cohesion-the likelihood of violent conflict increases. Second, investing in citizen security, justice, and jobs is essential to reducing violence. But there are major structural gaps in our collective capabilities to support these areas. Third, confronting this challenge effectively means that institutions need to change. International agencies and partners from other countries must adapt procedures so they can respond with agility and speed, a longer-term perspective, and greater staying power. Fourth, need to adopt a layered approach. Some problems can be addressed at the country level, but others need to be addressed at a regional level, such as developing markets that integrate insecure areas and pooling resources for building capacity Fifth, in adopting these approaches, need to be aware that the global landscape is changing. Regional institutions and middle income countries are playing a larger role. This means should pay more attention to south-south and south-north exchanges, and to the recent transition experiences of middle income countries.
