Abstract
Estimates of the area- and household idiosyncratic error distributions from household income and consumption regression models across 142 household surveys from 16 different countries, the type of models that underpin poverty maps, points to significant deviations from normality. Accounting for non-normality in Empirical Best estimation of local welfare is found to increase precision relative to normal-Empirical Best estimation. Although the gains in precision range between meaningful and marginal, it is always positive. Given that non-normal-Empirical Best estimation is furthermore easy to implement, there is no downside to using it.

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 South Africa’s Fragmented Cities: The Unequal Burden of Labor Market Frictions(Washington, DC: World Bank, 2026-01-08)Using high-resolution administrative, census, and satellite data, this paper shows that South African cities are characterized by spatial mismatches between where people live and where jobs are located, relative to 20 global peers. Areas within 5 kilometers of commercial centers have 9,300 fewer residents per square kilometer than expected, which is 60 percent below the global median. Poor, dense neighborhoods are most affected. In Johannesburg, a 10-percentile increase in distance from the nearest business hub corresponds to a 3.7-percentile drop in asset wealth (a proxy of household wellbeing) and 4.9-percentile drop in employment. In Cape Town, the declines are 4.0 and 3.7 percentiles, respectively. Employment is 87 percent lower in the poorest decile than the richest in Johannesburg and 61 percent lower in Cape Town. These findings suggest that South Africa’s spatial organization of people and economic activity constrains agglomeration and reinforces inequality. This methodology provides a scalable and standardized data-driven framework to analyze spatial accessibility and agglomeration frictions in complex, data-constrained urban systems.Publication The Evolution of Local Participatory Democracy in Nepal(Washington, DC: World Bank, 2025-11-05)Nepal is, according to its constitution, among the world’s most decentralized countries, with a long and complex tradition of local-level public participation. This paper traces the evolution of Nepal’s modern participatory institutions, examining the extent to which they are “induced” by external interventions versus being “organically” rooted in indigenous practices. The paper identifies three broad phases: an initial focus on participation in project implementation; a subsequent phase that expanded citizen engagement; and a third phase of citizen empowerment, culminating in the 2015 federal constitution, which granted unprecedented local autonomy. The analysis yields five key findings. First, over the past 50 years, successive reforms have progressively expanded opportunities for citizens to influence local decision-making. Second, these reforms have integrated traditional participatory mechanisms into formal institutions of local government. Third, although central-level initiatives exist, most participatory platforms continue to operate at the local level. Fourth, the federal constitution has created a new landscape of local democracy, embedding autonomy and accountability. Fifth, although they are still valued in many ethnic and territorial communities, traditional participatory practices are gradually disappearing. The paper concludes by offering policy recommendations to help donor agencies and governments strengthen Nepal’s democratic trajectory. It argues that effective interventions should build on Nepal’s deep participatory traditions while recognizing the constitutional reality of far-reaching local autonomy.Publication Institutional Capacity for Policy Implementation: An Analytical Framework(Washington, DC: World Bank, 2026-01-07)State capacity is an important prerequisite for policy implementation, yet at the country level it is difficult to measure, assess, and reform. This paper proposes a focus on institutional capacity: the ability of public institutions to implement the specific policy mandates for which they are responsible. Based on a review of existing literature, the paper defines the different dimensions that compose institutional capacity and groups them into two cross-cutting categories: organizational dimensions (personnel, financial resources, information systems, and management practices) and governance dimensions (transparency, independence, and accountability). The paper proposes measures for organizational and governance dimensions using existing data, shows intra-institutional variation of these measures within countries, and discusses how new data could be collected for better measurement of these concepts. Finally, the paper illustrates how the framework can be used to diagnose the sources of common problems related to weak policy implementation.Publication Closing the Gender Gap in Entrepreneurship: Overcoming Challenges in Law and Practice for Female Entrepreneurs(Washington, DC: World Bank, 2026-01-07)Despite significant strides toward gender equality, women around the world continue to encounter systemic obstacles that hinder their entrepreneurial success. This paper systematically reviews the literature on the barriers female entrepreneurs face and the solutions proposed to overcome these challenges. It discusses institutional factors, financial factors, human capital factors, and social and cultural factors. The literature overview is complemented by a series of stylized facts that illustrate how overcoming some of these existing barriers is correlated with improved women’s entrepreneurship and female labor force participation, drawing on the World Bank’s Women, Business and the Law database as well as the World Bank’s Enterprise Surveys. The findings underscore the need for creating an enabling environment where women can thrive as entrepreneurs.

Publication Estimation of Normal Mixtures in a Nested Error Model with an Application to Small Area Estimation of Poverty and Inequality(World Bank Group, Washington, DC, 2014-07)This paper proposes a method for estimating distribution functions that are associated with the nested errors in linear mixed models. The estimator incorporates Empirical Bayes prediction while making minimal assumptions about the shape of the error distributions. The application presented in this paper is the small area estimation of poverty and inequality, although this denotes by no means the only application. Monte-Carlo simulations show that estimates of poverty and inequality can be severely biased when the non-normality of the errors is ignored. The bias can be as high as 2 to 3 percent on a poverty rate of 20 to 30 percent. Most of this bias is resolved when using the proposed estimator. The approach is applicable to both survey-to-census and survey-to-survey prediction.Publication Micro-Level Estimation of Welfare(World Bank, Washington, DC, 2002-10)The authors construct and derive the properties of estimators of welfare that take advantage of the detailed information about living standards available in small household surveys and the comprehensive coverage of a census or large sample. By combining the strengths of each, the estimators can be used at a remarkably disaggregated level. They have a clear interpretation, are mutually comparable, and can be assessed for reliability using standard statistical theory. Using data from Ecuador, the authors obtain estimates of welfare measures, some of which are quite reliable for populations as small as 15,000 households--a "town." They provide simple illustrations of their use. Such estimates open up the possibility of testing, at a more convincing intra-country level, the many recent models relating welfare distributions to growth and a variety of socioeconomic and political outcomes.Publication Imputed Welfare Estimates in Regression Analysis(World Bank, Washington, D.C., 2004-04)The authors discuss the use of imputed data in regression analysis, in particular the use of highly disaggregated welfare indicators (from so-called "poverty maps"). They show that such indicators can be used both as explanatory variables on the right-hand side and as the phenomenon to explain on the left-hand side. The authors try out practical ways of adjusting standard errors of the regression coefficients to reflect the error introduced by using imputed, rather than actual, welfare indicators. These are illustrated by regression experiments based on data from Ecuador. For regressions with imputed variables on the left-hand side, the authors argue that essentially the same aggregate relationships would be found with either actual or imputed variables. They address the methodological question of how to interpret aggregate relationships found in such regressions.Publication GLS Estimation and Empirical Bayes Prediction for Linear Mixed Models with Heteroskedasticity and Sampling Weights : A Background Study for the POVMAP Project(World Bank Group, Washington, DC, 2014-09)This note adapts results by Huang and Hidiroglou (2003) on Generalized Least Squares estimation and Empirical Bayes prediction for linear mixed models with sampling weights. The objective is to incorporate these results into the poverty mapping approach put forward by Elbers et al. (2003). The estimators presented here have been implemented in version 2.5 of POVMAP, the custom-made poverty mapping software developed by the World Bank.Publication How Accurate Is a Poverty Map Based on Remote Sensing Data?(World Bank, Washington, DC, 2022-09)This paper assesses the reliability of poverty maps derived from remote-sensing data. Employing data for Malawi, it first obtains small area estimates of poverty by combining the Malawi household expenditure survey from 2010/11 with unit record population census data from 2008. It then ignores the population census data and obtains a second poverty map for Malawi by combining the survey data with predictors of poverty derived from remote sensing data. This allows for a clean comparison between the two poverty maps. The findings are encouraging - although that assessment depends somewhat on the evaluation criteria employed. The two approaches reveal the same patterns in the geography of poverty. However, there are instances where the two approaches obtain markedly different estimates of poverty. Poverty maps obtained using remote sensing data may do well when the decision maker is interested in comparisons of poverty between assemblies of areas, yet may be less reliable when the focus is on estimates for specific small areas.

Publication Guinea-Bissau Country Climate and Development Report(Washington, DC: World Bank, 2024-10-23)Guinea-Bissau is endowed with a wealth of natural resources, with the highest natural capital per capita in West Africa (US3,874 dollars per capita), which could be leveraged for sustainable and resilient growth. However, Guinea-Bissau faces significant development hurdles, such as high poverty rates, political instability, and economic challenges, including an over-reliance on cashew nuts. Rural poverty has increased, and the nation's infrastructure, education, and health care systems are underdeveloped. Climate change poses a severe threat, potentially impacting agriculture, fisheries, and infrastructure. Without adaptation, it could lead to a significant cut in real GDP per capita (minus 7.3 percent by 2050) and increase in poverty (with up to over 200,000 additional poor by 2050, that is, 5 percent of the expected population, in the worst scenario). The country's low greenhouse gas emissions are expected to rise, mainly due to agriculture and land-use changes, with deforestation being a major contributing factor. Although Guinea-Bissau is a low emitter, it has high mitigation ambitions, targeting a 30 percent reduction in greenhouse gas emissions by 2030. The Nationally Determined Contribution outlines significant climate actions, with initiatives focused on forest conservation, sustainable agriculture, and community development. However, the country's political instability, institutional weaknesses, and limited financial resources pose challenges to implementing these climate commitments, which depend heavily on external funding. The financial sector's underdevelopment and vulnerability to external shocks limit its ability to support green investments, though reforms could enhance resilience. Guinea-Bissau must consider its climate financing as development financing and vice-versa, engage the private sector, and integrate climate goals with national development plans to ensure a sustainable future. Concessional climate financing is vital due to the underdeveloped financial sector and the government’s limited borrowing capacity. Addressing Guinea-Bissau's vulnerability to climate change and its structural issues requires a cohesive approach that integrates development and climate strategies. This could involve improving governance, diversifying the economy, protecting natural capital, developing human capital, and investing in sustainable agriculture and infrastructure. The transition to a more sustainable and inclusive development pathway that supports economic growth is possible, but requires focusing on key strategic sectors, enhancing institutional capacity, and creating the conditions to mobilize finance. As a highly vulnerable country, there are myriad needs in the different sectors; however, to be more efficient and effective, Guinea-Bissau should prioritize actions in a few sectors, especially actions on biodiversity, agriculture, and social protection. Low carbon development, especially in energy and forestry sectors, could provide cost-efficient solutions and attract climate finance, including from the private sector, which will support the overall development agenda.Publication Kyrgyz Republic Country Climate and Development Report(Washington, DC: World Bank, 2025-11-03)This Country Climate and Development Report (CCDR) on the Kyrgyz Republic aims to support the country’s development goals amid a changing climate. The CCDR considers two policy scenarios up to 2050: the business-as-usual (BAU) and high-growth scenarios. As it quantifies the likely impacts of climate change on the Kyrgyz economy between now and 2050, the report highlights key government actions to best prepare for and adapt to climate impacts (referred to as “with adaptation” measures), with a particular focus on the time horizon up to 2030. The CCDR also outlines a path to net zero emissions by 2050 (referred to as “with mitigation” measures, “decarbonization,” or, simply, “net zero 2050”), highlighting associated development co-benefits.Publication Mongolia Country Climate and Development Report(Washington, DC: World Bank, 2024-10-22)Mongolia’s development prospects are uniquely challenged by both the impacts of climate change and the global shift toward a low-carbon economy. The country’s efforts toward decarbonization pose significant challenges given the structurally high-emission intensity of its economy. While challenging, climate action also presents Mongolia with opportunities to achieve important development benefits. The effects of climate risks and the shift away from coal will have diverse impacts across different regions, communities, and socioeconomic levels. The report assesses the critical interconnections between Mongolia’s development ambitions and climate change action and identifies ways to transition to a more economically diversified, inclusive, and resilient development path. It highlights key climate and transition risks affecting Mongolia’s future development and presents a pathway to enhance climate mitigation and adaptation. The report also makes a case for strengthening policies to enhance resilience to climate change and ensure a just transition, particularly for the most vulnerable. The report is structured as follows: section 1 gives introduction. Section 2 delves into the linkages between development and climate in Mongolia and presents model-based findings on the economic and poverty impacts of climate change under different scenarios. Section 3 covers four in-depth sectoral analyses. The first two mainly focus on adaptation to climate change in the agriculture and water sectors. The third considers prospects for the extraction sector, while the fourth sectoral analysis focuses on decarbonizing power and heat generation. Section 4 shifts the focus to how the government can boost resilience for climate-vulnerable populations. Section 5 outlines options for mobilizing private and public financing and private investments to support the green transition. Section 6 examines the existing institutional and governance structure for climate action and presents recommendations to improve its effectiveness, and section 7 concludes with a framework for prioritizing the policy actions outlined in this report.Publication Jobs in a Changing Climate: Insights from World Bank Group Country Climate and Development Reports Covering 93 Economies(Washington, DC: World Bank, 2025-11-05)The World Bank Group’s Country Climate and Development Reports (CCDRs) provide a crosscutting look at how countries’ development prospects, and the job opportunities they offer to their people, can be threatened by climate impacts and supported by climate policies. Climate change and policies affect jobs through impacts on productivity, energy and material efficiency, and physical, human, and natural capital. They can also transform employment opportunities, especially through complementary measures that help workers and firms adapt to and benefit from new technologies and production practices. Prepared by the World Bank, the International Finance Corporation (IFC), and the Multilateral Investment Guarantee Agency (MIGA), CCDRs integrate country perspectives, climate science and economic modeling, private sector information, and policy analysis to assess how countries can successfully grow and develop their economies and create jobs despite increasing climate risks and while achieving their climate objectives and commitments. Each CCDR starts from the country’s development priorities, opportunities, and challenges, and is developed in close consultation with governments, businesses, and civil society, ensuring the recommendations reflect national priorities. By combining evidence on adaptation, resilience, and emissions pathways, CCDRs highlight where climate action can reinforce development and job creation, and where targeted policies are needed to manage risks and smooth labor market transitions. Taken together, these elements can help create local jobs, ensure economic transitions are just and inclusive, and equip workers and firms to navigate the disruptions and opportunities of a changing climate and changing technologies.Publication Comoros Country Climate and Development Report(Washington, DC: World Bank, 2025-06-18)The Union of the Comoros (The Comoros) has significant vulnerability to climate change-related risks but has considerable opportunities to strengthen preparedness and resilience against these challenges. According to the Notre Dame Global Adaptation Index, the Comoros is the 29th-most vulnerable country to climate change and the 163rd most ready to adapt (out of 191). The Comoros archipelago is exposed to many natural hazards that adversely affect the country’s natural capital, people, and physical infrastructure. In 2014, the economic cost of climate-related disasters was estimated at 5.7 million dollars annually, equivalent to 9.2 percent of Gross Domestic Product (GDP). Between 2018 and 2023, as many as 11 tropical depressions or cyclones impacted the country, with Cyclone Kenneth causing the greatest damage, equivalent to 14 percent of GDP, resulting in total economic growth falling from 3.6 percent in 2018 to 1.9 percent in 2019. More than 345,000 people (40 percent of the population) were affected by the cyclone, with 185,000 people experiencing severe impacts and 12,000 people displaced. However, there is an opportunity for the country to grow more robust and shock-responsive, and to establish pre-positioned funding mechanisms to enhance future crisis response efforts. For the Comoros, adaptation and climate-resilient development are the key climate change focus areas, with the country projected to face 836 million dollars 2050 in additional costs due to climate-related impacts. Current plans to adapt to the impacts of climate change in the Comoros include efforts to improve water management, strengthen coastal protection, and develop climate-smart agriculture practices. Given the country’s reliance on its natural resource base for economic growth and mobility, protection of these resources from climate change will be essential for promoting resilient growth and development. In addition to growing the adaptive capacity of the country’s natural resource sectors, strategic economic diversification will be important to help minimize future climate impacts, and development activities will need to be undertaken in such a way as to attract low-carbon co-benefits. The Union of the Comoros is committed to addressing climate change through its Nationally Determined Contribution (NDC) and national priorities. The country’s NDC (which was revised in 2021 for a ten-year horizon) sets ambitious targets, with a goal of reducing greenhouse gas emissions by 23 percent by 2030. The country also plans to significantly increase the share of renewable energy in its energy portfolio, reaching 33 MW by 2030. This will not only promote low-carbon development but also reduce the country’s dependency on imported oil and coal, which currently make up 95 percent of the energy mix. Additionally, the Comoros has declared its intention to increase CO2 removals by 47 percent by 2030, compared to BAU.
