Abstract
This paper proposes a new measure of growth in shared prosperity, based on shifts in population shares of different income groups over time. This measure complements the definition of shared prosperity recently proposed by the World Bank in which income growth of the bottom 40 percent is examined. The new measure’s strengths arise from its close ties to countries’ national poverty lines and poverty measures, its focus on inclusion of the vulnerable population, and its identification of a population segment that is neither poor nor at significant risk of falling into poverty. The paper also offers a typology of scenarios for tracking shared prosperity under this measure. It provides illustrative examples using survey data from India, the United States, and Vietnam for the mid-to-late 2000s. Estimation results comparing the two approaches with measuring the evolution of shared prosperity are qualitatively consistent, and suggest that during this period, Vietnam enjoyed the greatest expansion in shared prosperity, followed by India and then the United States.

Publication The Future of Poverty(Washington, DC: World Bank, 2025-07-15)Climate change is increasingly acknowledged as a critical issue with far-reaching socioeconomic implications that extend well beyond environmental concerns. Among the most pressing challenges is its impact on global poverty. This paper projects the potential impacts of unmitigated climate change on global poverty rates between 2023 and 2050. Building on a study that provided a detailed analysis of how temperature changes affect economic productivity, this paper integrates those findings with binned data from 217 countries, sourced from the World Bank’s Poverty and Inequality Platform. By simulating poverty rates and the number of poor under two climate change scenarios, the paper uncovers some alarming trends. One of the primary findings is that the number of people living in extreme poverty worldwide could be nearly doubled due to climate change. In all scenarios, Sub-Saharan Africa is projected to bear the brunt, contributing the largest number of poor people, with estimates ranging between 40.5 million and 73.5 million by 2050. Another significant finding is the disproportionate impact of inequality on poverty. Even small increases in inequality can lead to substantial rises in poverty levels. For instance, if every country’s Gini coefficient increases by just 1 percent between 2022 and 2050, an additional 8.8 million people could be pushed below the international poverty line by 2050. In a more extreme scenario, where every country’s Gini coefficient increases by 10 percent between 2022 and 2050, the number of people falling into poverty could rise by an additional 148.8 million relative to the baseline scenario. These findings underscore the urgent need for comprehensive climate policies that not only mitigate environmental impacts but also address socioeconomic vulnerabilities.Publication Exports, Labor Markets, and the Environment(Washington, DC: World Bank, 2025-07-14)What is the environmental impact of exports? Focusing on 2000–20, this paper combines customs, administrative, and census microdata to estimate employment elasticities with respect to exports. The findings show that municipalities that faced increased exports experienced faster growth in formal employment. The elasticities were 0.25 on impact, peaked at 0.4, and remained positive and significant even 10 years after the shock, pointing to a long and protracted labor market adjustment. In the long run, informal employment responds negatively to export shocks. Using a granular taxonomy for economic activities based on their environmental impact, the paper documents that environmentally risky activities have a larger share of employment than environmentally sustainable ones, and that the relationship between these activities and exports is nuanced. Over the short run, environmentally risky employment responds more strongly to exports relative to environmentally sustainable employment. However, over the long run, this pattern reverses, as the impact of exports on environmentally sustainable employment is more persistent.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 Asymmetric Bank Distress Amplifier of Recessions(Washington, DC: World Bank, 2025-07-11)One defining feature of financial crises, evident in U.S. and international data, is asymmetric bank distress—concentrated losses on a subset of banks. This paper proposes a model in which shocks to borrowers’ productivity dispersion lead to asymmetric bank losses. The framework exhibits a “bank distress amplifier,” exacerbating economic downturns by causing costly bank failures and raising uncertainty about the solvency of banks, thereby pushing banks to deleverage. Quantitative analysis shows that the bank distress amplifier doubles investment decline and increases the spread by 2.5 times during the Great Recession compared to a standard financial accelerator model. The mechanism helps explain how a seemingly small shock can sometimes trigger a large crisis.Publication Impact of Heat Waves on Learning Outcomes and the Role of Conditional Cash Transfers(Washington, DC: World Bank, 2025-07-14)This paper evaluates the impact of higher temperatures on learning outcomes in Peru. The results suggest that 1 degree above 20°C is equivalent to 7 and 6 percent of a standard deviation of what a student learns in a year for math and reading tests, respectively. These results hold true when the main specification is changed, splitting the sample, collapsing the data at school level, and using other climate specifications. The paper aims to improve understanding of how to deal with the impacts of climate change on learning outcomes in developing countries. The evidence suggests that conditional cash transfer programs can mitigate the negative effects of higher temperatures on students’ learning outcomes in math and reading.

Publication Reducing Poverty through Growth and Social Policy Reform in Russia(Washington, DC: World Bank, 2006)Following the 1998 financial crisis, four out of every ten people slipped into poverty, not able to meet basic needs. Luckily, post-crisis economic rebound was impressive and broad-based, albeit uneven across sectors and regions. This title explores the nature of poverty, both nationally and regionally, to identify the groups with a high poverty risk. It then examines growth-poverty linkages through the labor market, as well as the contribution of growth and inequality to the recent poverty reduction. It also considers the expected impact of WTO accession on overall growth and poverty. Finally, it focuses on the scope for improving social policy in ways that will have a direct impact on the poor.Publication Poverty Reduction without Economic Growth? Explaining Brazil's Poverty Dynamics, 1985-2004(World Bank, Washington, DC, 2007-12)Brazil's slow pace of poverty reduction over the last two decades reflects both low growth and a low growth elasticity of poverty reduction. Using GDP data disaggregated by state and sector for a twenty-year period, this paper finds considerable variation in the poverty-reducing effectiveness of growth-across sectors, across space, and over time. Growth in the services sector was substantially more poverty-reducing than was growth in either agriculture or industry. Growth in industry had very different effects on poverty across different states and its impact varied with initial conditions related to human development and worker empowerment. The determinants of poverty reduction changed around 1994: positive growth rates and a greater (absolute) elasticity with respect to agricultural growth contributed to faster poverty reduction. But because there was so little of it, economic growth played a relatively small role in accounting for Brazil's poverty reduction between 1985 and 2004. The taming of hyperinflation (in 1994) and substantial expansions in social security and social assistance transfers, beginning in 1988, accounted for a larger share of the overall reduction in poverty.Publication Was Growth in Egypt Between 2005 and 2008 Pro-Poor? From Static to Dynamic Poverty Profile(2011-03-01)This paper presents a detailed picture of how sustained growth in Egypt over 2005-2008 affected different groups both above and below the poverty line. This analysis, based on the Household Income, Expenditure and Consumption Panel Survey conducted by Egypt s national statistical agency, compares the changes in the static poverty profiles (based on growth incidence curves on a cross-section of data) with poverty dynamics (relying on panel data, growth incidence curves and transition matrices). The two approaches yield contrasting results: the longitudinal analysis reveals that growth benefited the poor while the cross-sectional analysis shows that the rich benefitted even more. The paper also shows the importance of going beyond averages to look at the trajectories of individual households. Panel data analysis shows that the welfare of the average poor household increased by almost 10 percent per year between 2005 and 2008, enough to move out of poverty. Conversely however, many initially non-poor households were exposed to poverty. As a matter of fact, only 45 percent of the population in Egypt remained consistently out of (near-) poverty throughout the period, while the remaining 55 percent of Egyptians experienced at least one (near-) poverty episode. This high mobility is not a statistical artefact: it reflects the actual process of growth. Taking high vulnerability into account is essential when designing policies to protect the poor and to ensure that growth is really inclusive.Publication A Comparative Perspective on Poverty Reduction in Brazil, China and India(2009-10-01)Brazil, China and India have seen falling poverty in their reform periods, but to varying degrees and for different reasons. History left China with favorable initial conditions for rapid poverty reduction through market-led economic growth; at the outset of the reform process there were ample distortions to remove and relatively low inequality in access to the opportunities so created, though inequality has risen markedly since. By concentrating such opportunities in the hands of the better off, prior inequalities in various dimensions handicapped poverty reduction in both Brazil and India. Brazil's recent success in complementing market-oriented reforms with progressive social policies has helped it achieve more rapid poverty reduction than India, although Brazil has been less successful in terms of economic growth. In the wake of its steep rise in inequality, China might learn from Brazil's success with such policies. India needs to do more to assure that poor people are able to participate in both the country's growth process and its social policies; here there are lessons from both China and Brazil. All three countries have learned how important macroeconomic stability is to poverty reduction.Publication Urbanization and Poverty Reduction : The Role of Rural Diversification and Secondary Towns(World Bank, Washington, DC, 2013-04)A rather unique panel tracking more than 3,300 individuals from households in rural Kagera, Tanzania during 1991/4-2010 shows that about one in two individuals/households who exited poverty did so by transitioning from agriculture into the rural nonfarm economy or secondary towns. Only one in seven exited poverty by migrating to a large city, although those moving to a city experienced on average faster consumption growth. Further analysis of a much larger cross-country panel of 51 developing countries cannot reject that rural diversification and secondary town development lead to more inclusive growth patterns than metropolitization. Indications are that this follows because more of the poor find their way to the rural nonfarm economy and secondary towns, than to distant cities. The development discourse would benefit from shifting beyond the rural-urban dichotomy and focusing instead more on how best to urbanize and develop the rural nonfarm economy and secondary towns.

Publication Municipal Waste Management in Serbia - Situational Analysis(Washington, DC: World Bank, 2024-04-19)This report provides a baseline analysis of the existing situation in the municipal waste management sector in Serbia and underscores the importance of the sector in terms of achieving Sustainable Cities objectives. Reforms in the waste sector are a key component of a larger government commitment to a Green Transition. Ambitions to significantly improving the solid waste management system, in line with EU requirements, is well reflected in recently adopted policies and plans including the National Waste Management Program for the period2022 – 2031. There is a significant focus on the establishment of much needed basic disposal infrastructure. However, implementation remains slow, and some waste related targets will require further alignment and adjustment as the EU landscape continues to evolve.Publication Digital Opportunities in African Businesses(Washington, DC: World Bank, 2024-05-16)Adoption of digital technologies is widely acknowledged to boost productivity and employment, stimulate investment, and promote growth and development. Africa has already benefited from a rapid diffusion of information and communications technology, characterized by the widespread adoption of mobile phones. However, access to and use of digital technology among firms is uneven in the region, varying not just among countries but also within them. Consequently, African businesses may not be reaping the full potential benefits offered by ongoing improvements in digital infrastructure. Using rich datasets, “Digital Opportunities in African Businesses” offers a new understanding of the region’s incomplete digitalization—namely, shortfalls in the adoption and effective use of digital technology by firms to perform productive tasks. The research presented here also highlights the challenges in addressing incomplete digitalization, finding that the cost of machinery, equipment, and software, as well as the cost of connectivity to the internet, is significantly more expensive in Africa than elsewhere. “Digital Opportunities in African Businesses” outlines ways in which the private sector, with support from policy makers, international institutions, and regulators, can help bring down these costs, stimulating more widespread digitalization of the region’s firms, thereby boosting productivity and, by extension, economic development. This book will be relevant to anyone with an interest in furthering digitalization across Africa.Publication Integrating Gender in Land Projects(Washington, DC, 2023-10-08)This Toolkit is aimed at practitioners, bi-lateral and multi-lateral organizations, and community and non-governmental organizations involved in land projects, programs and activities. It draws from secondary research and applies experience to provide a pathway to the successful integration of gender into the design and implementation of land projects, programs and activities to ensure women’s rights to housing, land and property are recognized and protected. The Toolkit provides users with a blueprint for building strategies and good practices to overcome the legal, social, and structural barriers preventing women from exercising their land rights. It aims to ensure significant and meaningful participation of women in land projects in all spaces, rural, peri-urban, and urban. The Toolkit will often refer to women’s land rights (WLR) and this term is broadly addressing women’s rights to housing, land, and real property (HLP). The Toolkit is organized around four broad project stages: (1) scoping, (2) design, (3) implementation, and (4) evaluation; but with an emphasis on scoping and design.Publication South Asia’s Digital Opportunity(Washington, DC: World Bank, 2022-03-27)The report presents both the opportunities of and the bottlenecks for furthering the digital agenda. It emphasizes that the first step is to get the basics right. This includes enabling access to and adoption of high-quality affordable broadband, initiating a paradigm shift in building digital public platforms and accelerating digital financial services. Part of this includes integrating digital ID, digital payments, and data sharing platforms so they can become ‘digital stacks’ that allow service providers to build and innovate their own platforms and systems on top. Supporting digital businesses, fostering digital skills, and creating the necessary trust environment are also critical to the digital agenda. Further, a successful digital agenda at country levels would benefit from regional integration that entails cross-border connectivity, data infrastructure, and payment systems.Publication Global Economic Prospects, January 2025(Washington, DC: World Bank, 2025-01-16)Global growth is expected to hold steady at 2.7 percent in 2025-26. However, the global economy appears to be settling at a low growth rate that will be insufficient to foster sustained economic development—with the possibility of further headwinds from heightened policy uncertainty and adverse trade policy shifts, geopolitical tensions, persistent inflation, and climate-related natural disasters. Against this backdrop, emerging market and developing economies are set to enter the second quarter of the twenty-first century with per capita incomes on a trajectory that implies substantially slower catch-up toward advanced-economy living standards than they previously experienced. Without course corrections, most low-income countries are unlikely to graduate to middle-income status by the middle of the century. Policy action at both global and national levels is needed to foster a more favorable external environment, enhance macroeconomic stability, reduce structural constraints, address the effects of climate change, and thus accelerate long-term growth and development.
