Abstract
This study investigates the causal effects of long-term particulate matter 2.5 exposure on COVID-19 deaths, fatality rates, and cases in India by using an instrumental variables approach based on thermal inversion episodes. The estimation results indicate that a 1 percent increase in long-term exposure to particulate matter 2.5 leads to an increase in COVID-19 deaths by 5.7 percentage points and an increase in the COVID-19 fatality rate by 0.027 percentage point, but this exposure is not necessarily correlated with COVID-19 cases. People with underlying health conditions such as respiratory illness caused by exposure to air pollution might have a higher risk of death following SARS-CoV-2 infection. This finding might also apply to other countries where high levels of air pollution are a critical issue for development and public health.

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 Direct and Indirect Impacts of Transport Mobility on Access to Jobs: Evidence from South Africa(Washington, DC: World Bank, 2025-11-12)Access to jobs is essential for economic growth. In Africa, unemployment rates are notably high. This paper reexamines the relationship between transport mobility and labor market outcomes, with a particular focus on the direct and indirect effects of transport connectivity. As predicted by theory, wages are influenced by the level of commuting deterrence. Generally, higher earnings are associated with longer commute times and/or higher commuting costs. Local accessibility is also important, especially for individuals with time constraints. Both direct and indirect impacts are found to be significant in South Africa, where job accessibility has been challenging since the end of apartheid. For the direct impact, the wage elasticity associated with commuting costs is significant. Returns on commute are particularly high for women. Local accessibility to socioeconomic facilities, such as shops and health services, is also found to have a significant impact, consistent with the concept of mobility of care. To enhance employment, therefore, it is crucial to connect people not only to job locations but also to various socioeconomic points of interest, such as markets and hospitals, in an integrated manner. This integration will enable individuals to spend more time working and commuting longer distances.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 From Policy to Practice: Lessons from the Implementation of the Refugee Work Rights Policy in Ethiopia(Washington, DC: World Bank, 2025-11-10)This paper examines the early implementation of Ethiopia’s refugee work rights policy, with a focus on the issuance of permits that enable refugees to engage in economic activities. Building on significant legal and institutional advances under the 2019 Refugee Proclamation and subsequent directives, the analysis explores how these reforms are being operationalized in practice. Using a mixed-methods approach, combining document review, administrative data analysis, and semi-structured interviews, the paper identifies both progress and remaining challenges. Permit issuance has increased since the adoption of detailed operational guidance in 2024, reflecting the Government of Ethiopia’s commitment to operationalizing its progressive legal framework and ensuring that refugees can exercise their right to work. However, take-up remains modest, with about 5.2 percent of the working-age population holding a permit. Preliminary evidence suggests that coordination gaps, limited subnational capacity, low awareness among refugees and employers, and disincentives to formalize in a largely informal labor market are contributing to the low take-up. The paper offers policy suggestions, grounded in the Ethiopian context and emerging evidence, to help translate legal commitments into improved labor market outcomes for refugees.Publication Monitoring Global Aid Flows: A Novel Approach Using Large Language Models(Washington, DC: World Bank, 2025-11-04)Effective monitoring of development aid is the foundation for assessing the alignment of flows with their intended development objectives. Existing reporting systems, such as the Organisation for Economic Co-operation and Development’s Creditor Reporting System, provide standardized classification of aid activities but have limitations when it comes to capturing new areas like climate change, digitalization, and other cross-cutting themes. This paper proposes a bottom-up, unsupervised machine learning framework that leverages textual descriptions of aid projects to generate highly granular activity clusters. Using the 2021 Creditor Reporting System data set of nearly 400,000 records, the model produces 841 clusters, which are then grouped into 80 subsectors. These clusters reveal 36 emerging aid areas not tracked in the current Creditor Reporting System taxonomy, allow unpacking of “multi-sectoral” and “sector not specified” classifications, and enable estimation of flows to new themes, including World Bank Global Challenge Programs, International Development Association–20 Special Themes, and Cross-Cutting Issues. Validation against both Creditor Reporting System benchmarks and International Development Association commitment data demonstrates robustness. This approach illustrates how machine learning and the new advances in large language models can enhance the monitoring of global aid flows and inform future improvements in aid classification and reporting. It offers a useful tool that can support more responsive and evidence-based decision-making, helping to better align resources with evolving development priorities.

Publication India’s Economic Growth and Environmental Sustainability : What Are the Tradeoffs?(2012-09)One of the key environmental problems facing India is that of particle pollution from the combustion of fossil fuels. This has serious health consequences and with the rapid growth in the economy these impacts are increasing. At the same time, economic growth is an imperative and policy makers are concerned about the possibility that pollution reduction measures could reduce growth significantly. This paper addresses the tradeoffs involved in controlling local pollutants such as particles. Using an established Computable General Equilibrium model, it evaluates the impacts of a tax on coal or on emissions of particles such that these instruments result in emission levels that are respectively 10 percent and 30 percent lower than they otherwise would be in 2030. The main findings are as follows: (i) A 10 percent particulate emission reduction results in a lower gross domestic product but the size of the reduction is modest; (ii) losses in gross domestic proudct from the tax are partly offset by the health gains from lower particle emissions; (iii) the taxes reduce emissions of carbon dioxide by about 590 million tons in 2030 in the case of the 10 percent reduction and 830 million tons in the case of the 30 percent reduction; and (iv) taken together, the carbon dioxide reduction and the health benefits are greater than the loss of gross domestic product in both cases.Publication Environmental Issues in the Power Sector : Long-Term Impacts and Policy Options for Karnataka(Washington, DC, 2004-10)This study of the long-term environmental impacts and policy options for power sector development in Karnataka, is one of a series undertaken by the Bank, in cooperation with the Government of India and state governments. It is a follow-up to the broader study Environmental Issues in the Power Sector (EIPS) (ESMAP/World Bank 1998), and the general methodology developed for EIPS, is used for this analysis. The study begins by evaluating the impacts of the baseline reform scenario, and then perturbs this scenario for the options examined, including a scenario of "stalled reform," to enable assessment of the costs and benefits of reform. Because Karnataka has already implemented significant reform measures, "no reform" (as used in the original 1998 EIPS study) is not a useful scenario. The critical insight of this study is that the damage costs of emissions from grid-based fossil plants are between one and two orders of magnitude smaller than those of captive and self-generation units, emissions from which are essentially uncontrolled, and occur in more populated areas at, or near ground level. The report addresses the coal-by-wire option, which would shift from Karnataka to the producing states the environmental impacts that are associated with coal generation. It may well be that the producing states will as a result, have to impose much higher coal royalties, and, it is also likely that coal-producing areas would encounter water resource constraints: while Karnataka is a drought-prone state for which the opportunity costs of consumptive use are higher than in the eastern states of Bihar and Orissa, it is unclear if mine-mouth projects in those states could serve the bulk of the power needs of both southern, and northern India in the decade 2010-2020. The study highlights that power sector reform is the single most important step that may be taken to mitigate the environmental impacts of the power sector, while tariff reform is the second most important policy option for environmental sustainability, with demand-side management being a win-win factor. Consumptive water use for thermal generation is a major issue in Karnataka. Gas combined-cycle combustion turbines, which are attractive for their relatively low air emissions, consume only one third of the water that a steam-cycle project uses. The use of imported coal would be a viable option for Karnataka, if the existing customs duty on imported coal were to be removed. This study shows that the probable capital cost decreases for wind power, would still permit an acceptable rate of return for developers, but that the pace of new projects may slow as only the best sites will warrant development under the new tariff.Publication Environmental Issues in the Power Sector : Long-Term Impacts and Policy Options for Rajasthan(Washington, DC, 2004-10)Recognizing the links between electricity development, and the environment, the Bank, in cooperation with the Government of India and the State governments of Karnataka and Rajasthan, implemented assessments of environmental policies in the Power Sector in the Indian states of Karnataka and Rajasthan. This work for the State of Rajasthan is designed to examine, and quantify a broad number of options for reducing the environmental impacts of power development in general, and power reform in particular. The strategic objective is to provide the analytical basis for assisting these states develop power sector policies, and strategies that are environmentally sustainable. The study begins by evaluating the impacts of the baseline reform scenario, and then perturbs this scenario for the options examined, including a scenario of "stalled reform," to enable assessment of the costs, and benefits of reform. Because Rajasthan has already implemented significant reform measures, "no reform" (as used in the original 1998 EIPS study) is not a useful scenario. The major findings of this study may be summarized as follows: 1) Power sector reform is the single most important step that may be taken to mitigate the environmental impacts of the power sector. The difference in emissions (and damage costs) between reform, and stalled reform far exceeds the difference across all other options, such as DSM, or the use of renewables. 2) The further addition of environmental benefits yields the social net benefit. The only (significant) winners of stalled reform are the pilferers, who would benefit from the failure to further reduce non-technical losses. Unless the reforms progress to completion, all other stakeholders, including the environment, would lose.Publication Incorporating Energy Cycle Externality Costs and Benefits in India's Power System Planning Mechanisms(World Bank, Washington, DC, 2007-04)The power sector in India plays a fundamental role in the economic development process. The country faces formidable challenges in meeting its energy needs in an environmentally sustainable manner and at reasonable costs. The planning and operation of the sector has hitherto been conducted without due regard to the environmental consequences. As a result, additions to capacity in recent years have been sub-optimal. Moreover different types of capacity are treated differently. Hydropower is required directly to bear more of its external environmental costs than other sources. The recent Supreme Court ruling has reinforced this tendency. Looking forward, much of the large capacity additions required over the next few years are likely to be coal-fired, with concomitant effects on the country's environment. Against that background, the paper looks at India's power generation planning process; whether and how it might adapt in the light of increased attention to environmental costs and benefits; and if there are other, better ways of internalizing environment externalities. It takes as its starting point the conclusions of the companion paper by Anil Markandya. These are that the external environmental costs of fossil fuel generation are as high or higher than estimates derived for developed countries; that estimates of the external costs of both fossil-fuelled and hydro for India should now be determined more precisely and used at the strategic level in planning, at the regulatory level in setting standards, in designing economic instruments and in plant sitting decisions; and that the polluter pays principle, which currently applies in the case of hydro, should also be applied in other power sector developments.Publication Power System Planning in India : Incorporating Environmental Externality Costs and Benefits(Washington, DC, 2007-04)This paper has been prepared in accordance with the terms of reference for a study on power system planning in India: incorporating externality costs and benefits. It reviews estimates of the external costs of power in international studies as well as in India and compares the figures available. It also comments on the validity of the external cost estimates available and the use made of them in power system planning and regulation both outside and inside India. The structure is as follows. Section two reviews the external cost estimates of electricity generation in the European Union (EU), and other countries. It also reports some recent work on the external costs associated with transmission. Some comments for the range of estimates are offered. Section three reviews a few studies on external costs for India and compares those with the international estimates. Section four discusses the use made of external cost data in power system planning and regulation both internationally and in India and makes some recommendations for possible reforms in the Indian case. Section five reviews the Indian and international estimates of external costs of hydro and section six does the same for resettlement and rehabilitation (RR) costs. Section seven offers some conclusions.

Publication The Government Analytics Handbook(Washington, DC: World Bank, 2023-09-28)The Government Analytics Handbook presents frontier evidence and practitioner insights on how to leverage data to strengthen public administration. Covering a range of microdata sources—such as administrative data and public servant surveys—as well as tools and resources for undertaking the analytics, it transforms the ability of governments to take a data-informed approach to diagnose and improve how public organizations work. The "Handbook" is a must-have for practitioners, policy makers, academics, and government agencies. It is available as a single volume in print or digital formats, and as chapters for modular use. Additional tools, data and background information are available at worldbank.org/governmentanalytics. “Governments have long been assessed using aggregate governance indicators, giving us little insight into their diversity and how they can practically be improved. This pioneering handbook shows how microdata can be used to give scholars and practitioners granular and real insights into how states work, and practical guidance on the process of state-building.” —Francis Fukuyama, Stanford University, author of State-Building: Governance and World Order in the 21st Century - "The Government Analytics Handbook is the most comprehensive work on practically building government administration I have ever seen, helping practitioners to change public administration for the better.” —Francisco Gaetani, Special Secretary for State Transformation, Government of Brazil - “The machinery of the state is central to a country’s prosperity. This handbook provides insights and methodological tools for creating a better shared understanding of the realities of a state, to support the redesign of institutions, and improve the quality of public administration.” —James Robinson, University of Chicago, coauthor of Why Nations FailPublication The Changing Wealth of Nations 2021(Washington, DC: World Bank, 2021-10-27)It is now clear that a narrow focus on the growth of gross domestic product (GDP) is insufficient to achieve humanity’s aspirations for sustainable prosperity. Wellfunctioning ecosystems and educated populations are requisites for sustainable wellbeing. These and other too-often-neglected ingredients of national wealth must be addressed if the development path is to be sustainable. The Changing Wealth of Nations 2021: Managing Assets for the Future provides the most comprehensive accounting of the wealth of nations, an in-depth analysis of the evolution of wealth, and pathways to build wealth for the future. This report—and the accompanying global database—firmly establishes comprehensive wealth as a measure of sustainability and a key component of country analytics. It expands the coverage of wealth accounts and improves our understanding of the quality of all assets, notably, natural capital. Wealth—the stock of produced, natural, and human capital—is measured as the sum of assets that yield a stream of benefits over time. Changes in the wealth of nations matter because they reflect the change in countries’ assets that underpin future income. Countries regularly track GDP as an indicator of their economic progress, but not wealth, and national wealth has a more direct and long-term impact on people’s lives. This report provides a new set of tools and analysis to help policy makers navigate risks and to guide collective action. Wealth accounts can be applied in macroeconomic analysis to areas of major policy concern such as climate change and natural resource management. This report can be used to look beyond GDP, to gauge nations’ economic well-being, and to promote sustainable prosperity.Publication Sourcebook on the Foundations of Social Protection Delivery Systems(Washington, DC: World Bank, 2020-07-30)The Sourcebook synthesizes real-world experiences and lessons learned of social protection delivery systems from around the world, with a particular focus on social and labor benefits and services. It takes a practical approach, seeking to address concrete “how-to” questions, including: How do countries deliver social protection benefits and services? How do they do so effectively and efficiently? How do they ensure dynamic inclusion, especially for the most vulnerable and needy? How do they promote better coordination and integration—not only among social protection programs but also programs in other parts of government? How can they meet the needs of their intended populations and provide a better client experience? The Sourcebook structures itself around eight key principles that can frame the delivery systems mindset: (1) delivery systems evolve over time, do so in a non-linear fashion, and are affected by the starting point(s); (2) additional efforts should be made to “do simple well”, and to do so from the start rather than trying to remedy by after-the-fact adding-on of features or aspects; (3) quality implementation matters, and weaknesses in the design or structure of any core system element will negatively impact delivery; (4) defining the “first mile” for people interface greatly affects the system and overall delivery, and is most improved when that “first mile” is understood as the weakest link in delivery systems); (5) delivery systems do not operate in a vacuum and thus should not be developed in silos; (6) delivery systems can contribute more broadly to government’s ability to intervene in other sectors, such as health insurance subsidies, scholarships, social energy tariffs, housing benefits, and legal services; (7) there is no single blueprint for delivery systems, but there are commonalities and those common elements constitute the core of the delivery systems framework; (8) inclusion and coordination are pervasive and perennial dual challenges, and they contribute to the objectives of effectiveness and efficiency.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 The Journey Ahead(Washington, DC: World Bank, 2024-10-31)The Journey Ahead: Supporting Successful Migration in Europe and Central Asia provides an in-depth analysis of international migration in Europe and Central Asia (ECA) and the implications for policy making. By identifying challenges and opportunities associated with migration in the region, it aims to inform a more nuanced, evidencebased debate on the costs and benefits of cross-border mobility. Using data-driven insights and new analysis, the report shows that migration has been an engine of prosperity and has helped address some of ECA’s demographic and socioeconomic disparities. Yet, migration’s full economic potential remains untapped. The report identifies multiple barriers keeping migration from achieving its full potential. Crucially, it argues that policies in both origin and destination countries can help maximize the development impacts of migration and effectively manage the economic, social, and political costs. Drawing from a wide range of literature, country experiences, and novel analysis, The Journey Ahead presents actionable policy options to enhance the benefits of migration for destination and origin countries and migrants themselves. Some measures can be taken unilaterally by countries, whereas others require close bilateral or regional coordination. The recommendations are tailored to different types of migration— forced displacement as well as high-skilled and low-skilled economic migration—and from the perspectives of both sending and receiving countries. This report serves as a comprehensive resource for governments, development partners, and other stakeholders throughout Europe and Central Asia, where the richness and diversity of migration experiences provide valuable insights for policy makers in other regions of the world.
