Abstract
In Europe, it can be estimated that hydro-meteorological information and early warning systems save several hundreds of lives per year, avoid between 460 million and 2.7 billion Euros of disaster asset losses per year, and produce between 3.4 and 34 billion of additional benefits per year through the optimization of economic production in weather-sensitive sectors (agriculture, energy, etc.). The potential for similar benefits in the developing world is not only proportional to population, but also to increased hazard risk due to climate and geography, as well as increased exposure to weather due to the state of infrastructure. This analysis estimates that the potential benefits from upgrading to developed-country standards the hydro-meteorological information production and early warning capacity in all developing countries include: (i) between 300 million and 2 billion USD per year of avoided asset losses due to natural disasters; (ii) an average of 23,000 saved lives per year, which is valued between 700 million and 3.5 billion USD per year using the Copenhagen Consensus guidelines; and (iii) between 3 and 30 billion USD per year of additional economic benefits. The total benefits would reach between 4 and 36 billion USD per year. Because some of the most expensive components of early warning systems have already been built (e.g., earth observation satellites, global weather forecasts), these investments are relatively modest, estimated here around 1 billion US per year, reaching benefit-cost ratios between 4 and 36.

Publication Intergenerational Income Mobility around the World(Washington, DC: World Bank, 2025-07-09)This paper introduces a new global database with estimates of intergenerational income mobility for 87 countries, covering 84 percent of the world’s population. This marks a notable expansion of the cross-country evidence base on income mobility, particularly among low- and middle-income countries. The estimates indicate that the negative association between income mobility and inequality (known as the Great Gatsby Curve) continues to hold across this wider range of countries. The database also reveals a positive association between income mobility and national income per capita, suggesting that countries achieve higher levels of intergenerational mobility as they grow richer.Publication International Activity and Female Labor Participation: New Evidence for Services Firms in Developing Countries(Washington, DC: World Bank, 2025-09-03)Using a cross-section of more than 33,000 services firms in 104 low- and middle-income countries from the World Bank’s Enterprise Surveys, this paper examines whether the female labor share premium of international firms relative to non-international firms in manufacturing also holds for services firms. Unlike the manufacturing sector, the paper finds a negative relationship between exporting and global value chain participation and the female labor share for services firms, while no relationship is found for importing or foreign ownership status, controlling for firm output, productivity, technology intensity, and fixed effects. The female labor share gap for exporters was larger before COVID-19, and the gap for global value chain participants is no longer significant after COVID-19. Controlling for sectoral relative wages between men and women does not change the findings in a smaller subsample of economies. Controlling for female top management and ownership reveals a female labor share gap for exporters, global value chain participants, and importers. Using an alternative estimator and data set confirms the female labor share gap in services firms. This may be attributed to the sectoral segregation between women and men, with women tending to pursue work opportunities in less skill- and export-intensive services sectors compared to men.Publication Children in Monetary Poor Households: Global, Regional, and Select National Trends in the Progress against Child Poverty(Washington, DC: World Bank, 2025-09-05)This paper presents the first estimates of extreme child poverty and child poverty using the World Bank’s recently revised international poverty lines. Using the international poverty line of $3.00 per day and the higher $8.30 per day poverty line (both expressed in 2021 purchasing power parity), the paper provides new results of the global and regional trends over 2014–24. The estimates show that 19.2 percent of children, approximately 412 million children, were living on less than $3.00 (2021 PPP) per day as of 2024, a reduction from 507 million children in 2014. This long-term decrease was slower than that for the general population. At the higher line of $8.30, the child poverty rate in 2024 was 65.9 percent, representing around 1.4 billion children, a drop from the 73.1 percent registered in 2014. At the regional level, the East Asia and Pacific and South Asia regions witnessed significant reductions in child poverty and extreme child poverty between 2014 and 2024, and the Europe and Central Asia and Latin America and the Caribbean regions showed reductions mostly in child poverty. In the same period, there was an increase in extreme child poverty in the Middle East and North Africa region. Sub-Saharan Africa experienced a “lost decade” of child poverty reduction between 2014 and 2024, increasing its concentration of global poverty. In 2024, Sub-Saharan Africa hosted more than three-quarters of children in extreme poor households (more than 311 million children), although its share of the global child population was around 23 percent. Country-level results show evidence of regional heterogeneity in progress against extreme child poverty.Publication Engineering Ukraine’s Wirtschaftswunder(Washington, DC: World Bank, 2025-07-29)As Ukraine emerges from the devastation of war, it faces a historic opportunity to engineer its own Wirtschaftswunder—a productivity-driven economic transformation akin to post-war West Germany. While investment-led growth may offer quick wins, it is efficiency, innovation, and institutional reform that will determine Ukraine’s long-term economic trajectory. Drawing on rich micro-level firm data spanning 25 years, this paper uncovers deep structural distortions that have suppressed creative destruction and productivity in Ukraine. It finds that business dynamism is on the decline, alongside rising market concentration among incumbent businesses, including low productivity state owned enterprises. To inform priorities for reviving business dynamism, this study develops a model of creative destruction drawing on Acemoglu et al. (2018) and Akcigit et al. (2021). The quantitative assessment highlights that policies that discipline entrenched incumbents are the bedrock for reviving business dynamism and engineer Ukraine’s Wirtschaftswunder. Policies targeting specific types of firms have limited efficacy when incumbents run wild.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 The Cost of Adapting to Extreme Weather Events in a Changing Climate(World Bank, Dhaka, 2011-12)Bangladesh is one of the most climate vulnerable countries in the world. Situated in the delta of the Ganges, Brahmaputra, and Meghna (GBM) rivers, the country is exposed to a range of river and rainwater flood hazards due to climate variability, the timing, location, and extent of which depend on precipitation in the entire GBM basin. The Government of Bangladesh is fully committed to global climate-change advocacy and action, having already invested heavily in adaptation measures and policies. In recent decades, the government has invested more than US$10 billion to protect its population and assets in the floodplains. Given the uncertain magnitude and timing of the added risks from climate change, it is essential to identify the costs of climate proofing Bangladesh's critical infrastructure from intensified monsoon floods and cyclonic storm surges. Previously, few if any detailed studies have been developed on the costs of climate-proofing the country's infrastructure assets from inland monsoon floods and cyclones. Most analytical work to date has been confined to case studies, with relatively limited sets of locations, impacts, and adaptation measures. This study aims to fill that knowledge gap by providing detailed vulnerable population estimates and estimates of the incremental costs of asset adaptation out to the year 2050. It is part of a larger World Bank-supported study, entitled Economics of Adaptation to Climate Change (EACC), funded by the governments of the United Kingdom, the Netherlands, and Switzerland.Publication Acting Today for Tomorrow(Washington, DC, 2012)Pacific island countries continue to be among the most vulnerable in the world: they combine high exposure to frequent and damaging natural hazards with low capacity to manage the resulting risks. Their vulnerability is exacerbated by poorly planned socioeconomic development, which has increased exposure and disaster losses, and by climate change, which has increased the magnitude of cyclones, droughts, and flooding. Currently, inefficient management of risks negates development gains and incurs large costs for national and local governments. Progress in reducing vulnerability has been retarded in part because of fundamental problems with coordination and cooperation among relevant actors at all levels. 'acting today for tomorrow' provides case studies, data, and analysis from the Pacific region to make a case for climate-and disaster-resilient development as being the most appropriate way to address the above challenges. It outlines what the consequences are of not acting today to reduce risk, what important lessons have emerged from the last decade, and what must be done to move toward resilient development in Pacific island countries. The document is intended for an audience of practitioners and policymakers at all levels across all relevant sectors. Its analysis and recommendations are meant to inform disaster risk reduction (DRR) and climate change adaptation (CCA) planning across a range of institutions. Over the last decade, some important lessons have emerged about what works, and what does not work, to reduce vulnerability. It is clear now that project-based DRR and CCA initiatives with relatively short time frames encourage fragmented efforts, inhibit carryover across initiatives, and ultimately do little to reduce underlying vulnerability in a lasting way. To achieve robust and effective political authority, leadership, and accountability for more resilient development, governments should anchor coordination of DRR and CCA in a high level central ministry/body both at national and regional levels and ensure that leaders are knowledgeable about disaster and climate risk management.Publication Five Feet High and Rising : Cities and Flooding in the 21st Century(2011-05-01)Urban flooding is an increasingly important issue. Disaster statistics appear to show flood events are becoming more frequent, with medium-scale events increasing fastest. The impact of flooding is driven by a combination of natural and human-induced factors. As recent flood events in Pakistan, Brazil, Sri Lanka and Australia show, floods can occur in widespread locations and can sometimes overwhelm even the best prepared countries and cities. There are known and tested measures for urban flood risk management, typically classified as structural or engineered measures, and non-structural, management techniques. A combination of measures to form an integrated management approach is most likely to be successful in reducing flood risk. In the short term and for developing countries in particular, the factors affecting exposure and vulnerability are increasing at the fastest rate as urbanization puts more people and more assets at risk. In the longer term, however, climate scenarios are likely to be one of the most important drivers of future changes in flood risk. Due to the large uncertainties in projections of climate change, adaptation to the changing risk needs to be flexible to a wide range of future scenarios and to be able to cope with potentially large changes in sea level, rainfall intensity and snowmelt. Climate uncertainty and budgetary, institutional and practical constraints are likely to lead to a combining of structural and non-structural measures for urban flood risk management, and arguably, to a move away from what is sometimes an over-reliance on hard-engineered defenses and toward more adaptable and incremental non-structural solutions.Publication Economics of Adaptation to Climate Change : Samoa(Washington, DC, 2010)Over the last two decades Samoa has suffered major damage from two cyclones in 1990-91, minor damage from a third cyclone in 2004, and an earthquake tsunami in 2009. Changes in the scale and impact of these types of natural disasters are likely to be important consequences of climate change for the country because the increases in sea level and in average sea surface temperatures will increase theintensity and damage from major storms. Other potential impacts are linked to changes in the weather patterns associated with El Niño Southern Oscillation (ENSO) events. The primary concern focuses on the impact on agriculture, especially in periods of lower precipitation following strong El Niño episodes.This study examines the consequences of an increase in average temperatures of up to 1°C by 2050 and up to 2.75°C by 2100 for the frequency and intensity of major cyclones that hit the islands. Estimates of the economic damage caused by storms in the past have been used to calibrate a damage function that yields an estimated increase in the expected value of economic damage as the peak wind speeds for storms with return periods of 10, 50, or 100 years rise over time. In this framework the key element of adaptation is to ensure that buildings and other assets are designed to standards that enable them to cope with the greater wind stresses and more intense precipitation associated with worse storms.Publication Vulnerability of Bangladesh to Cyclones in a Changing Climate : Potential Damages and Adaptation Cost(2010-04-01)This paper integrates information on climate change, hydrodynamic models, and geographic overlays to assess the vulnerability of coastal areas in Bangladesh to larger storm surges and sea-level rise by 2050. The approach identifies polders (diked areas), coastal populations, settlements, infrastructure, and economic activity at risk of inundation, and estimates the cost of damage versus the cost of several adaptation measures. A 27-centimeter sea-level rise and 10 percent intensification of wind speed from global warming suggests the vulnerable zone increases in size by 69 percent given a +3-meter inundation depth and by 14 percent given a +1-meter inundation depth. At present, Bangladesh has 123 polders, an early warning and evacuation system, and more than 2,400 emergency shelters to protect coastal inhabitants from tidal waves and storm surges. However, in a changing climate, it is estimated that 59 of the 123 polders would be overtopped during storm surges and another 5,500 cyclone shelters (each with the capacity of 1,600 people) to safeguard the population would be needed. Investments including strengthening polders, foreshore afforestation, additional multi-purpose cyclone shelters, cyclone-resistant private housing, and further strengthening of the early warning and evacuation system would cost more than $2.4 billion with an annual recurrent cost of more than $50 million. However, a conservative damage estimate suggests that the incremental cost of adapting to these climate change related risks by 2050 is small compared with the potential damage in the absence of adaptation measures.

Publication Weather and Climate Services in Europe and Central Asia : A Regional Review(Washington, DC : World Bank, 2008)This paper reviews the status of weather and climate services in Europe and Central Asia (ECA).Worldwide, the accuracy and value of weather and climate services are rising, bringing great economic benefits. However, many National Meteorological and Hydrological Services (NMHSs) in Europe and Central Asia are in decline. As a result, these potential gains are often missed. Much more could be done to mitigate weather disasters, support the productivity of smallholding and commercial agriculture, conserve energy, and promote safe aviation and transport by road and rail. Although NMHS capacity deficiencies are serious, they could be significantly remedied by relatively modest but sustained investments. Economic assessments indicate substantial benefit-to-cost ratios for such initiatives. A strategy for NMHS service improvement requires assessment of national climate, user needs, NMHS status and provision of services, and the economic benefits of an upgrade to weather and climate services. recommendations for agency modernization should include (a) a prioritized plan for improving data delivery to national users, (b) identification of the highest-priority infrastructure investments, and (c) a reasonable phasing plan for overall modernization.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 Global Rapid Post-Disaster Damage Estimation (GRADE) Report(Washington, DC: World Bank, 2024-08-05)This Global Rapid Post-Disaster Damage Estimation (GRADE) report provides a synopsis of the estimated direct economic damage in Saint Vincent and the Grenadines (SVG) due to the passage Hurricane Beryl. The report is based on a rapid and remote post disaster damage assessment that follows the established GRADE methodology. Hurricane Beryl passed over southern SVG on July 1, 2024. Wind speeds ranged from a Category 4 hurricane in the southern Grenadines, then lessening to the north with Tropical Storm force winds felt on the main island of Saint Vincent. The objective of this report is to provide an estimate of the direct economic damage to physical assets caused by Hurricane Beryl in Saint Vincent and the Grenadines (SVG) and to provide information on the spatial distribution of damages to support development of a roadmap for recovery and reconstruction.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 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.
