Abstract
This paper critically reviews the literature on finance and inequality, highlighting substantive gaps in the literature. Finance plays a crucial role in most theories of persistent inequality. Unsurprisingly, therefore, economic theory provides a rich set of predictions concerning both the impact of finance on inequality and about the relevant mechanisms. Although subject to ample qualifications, the bulk of empirical research suggests that improvements in financial contracts, markets, and intermediaries expand economic opportunities and reduce inequality. Yet, there is a shortage of theoretical and empirical research on the potentially enormous impact of formal financial sector policies, such as bank regulations and securities law, on persistent inequality. Furthermore, there is no conceptual framework for considering the joint and endogenous evolution of finance, inequality, and economic growth.

    The Economic Value of Weather Forecasts: A Quantitative Systematic Literature Review
    (Washington, DC: World Bank, 2025-09-10) Farkas, Hannah; Linsenmeier, Manuel; Talevi, Marta; Avner, Paolo; Jafino, Bramka Arga; Sidibe, Moussa
    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.

    Direct and Indirect Impacts of Transport Mobility on Access to Jobs: Evidence from South Africa
    (Washington, DC: World Bank, 2025-11-12) Iimi, Atsushi
    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.

    The Macroeconomic Implications of Climate Change Impacts and Adaptation Options
    (Washington, DC: World Bank, 2025-05-29) Abalo, Kodzovi; Boehlert, Brent; Bui, Thanh; Burns, Andrew; Castillo, Diego; Chewpreecha, Unnada; Haider, Alexander; Hallegatte, Stephane; Jooste, Charl; McIsaac, Florent; Ruberl, Heather; Smet, Kim; Strzepek, Ken
    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.

    From Policy to Practice: Lessons from the Implementation of the Refugee Work Rights Policy in Ethiopia
    (Washington, DC: World Bank, 2025-11-10) Perez, Ana Maria; Rozo, Sandra V.
    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.

    Monitoring Global Aid Flows: A Novel Approach Using Large Language Models
    (Washington, DC: World Bank, 2025-11-04) Luo, Xubei; Rajasekaran, Arvind Balaji; Scruggs, Andrew Conner
    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.

    Finance and Economic Opportunity
    (World Bank, Washington, DC, 2008-01) Levine, Ross; Demirgüç-Kunt, Asli
    An influential body of theoretical research and an emerging line of empirical work suggest that the operation of the formal financial system affects the degree to which economic opportunities are defined by talent and initiative rather than by parental wealth and social connections. This paper discusses the theory of how financial markets influence economic opportunity and reviews recent empirical work on the relation between formal financial systems and poverty, income inequality, and economic opportunity. The authors consider recent efforts to measure the ability of households and small enterprises to access financial services, the impact of this access, and the mechanisms through which finance affects poverty and inequality. The authors argue that considerably more research is needed to identify which formal financial sector policies enhance the operation of the financial system in ways that expand the economic horizons of the economically disenfranchised.

    Credit-Constrained in Risky Activities?
    (World Bank, Washington, DC, 2012-05) Grimm, Michael; Lange, Simon; Lay, Jann
    Micro and Small Enterprises (MSEs) in developing countries are typically considered to be severely credit constrained. Additionally, high business risks may partly explain why capital stocks of MSEs remain low. This article analyzes the determinants of capital stocks of MSEs in poor economies focusing on credit constraints and risk. The analysis is based on a unique, albeit cross sectional but backward looking, micro data set on MSEs covering the economic capitals of seven West-African countries. The main result is that capital market imperfections indeed seem to explain an important part of the variation in capital stocks in the early lifetime of MSEs. Furthermore, the analyses show that risk plays a key role for capital accumulation. Risk-averse individuals seem to adjust their initially low capital stocks upwards when enterprises grow older. MSEs in risky activities owned by wealthy individuals even seem to over-invest when they start their business and adjust capital stocks downwards subsequently. As other firms simultaneously suffer from capital shortages, such behavior may imply large inefficiencies.

    Informal Sector Dynamics in Times of Fragile Growth
    (World Bank, Washington, DC, 2011-09) Vaillant, Julia; Grimm, Michael; Lay, Jann; Roubaud, François
    This paper investigates the dynamics of the informal sector in Madagascar during a period of fragile growth. Overall, the behavior of informal firms in terms of earnings, employment and capital accumulation points to a degree of heterogeneity which goes beyond a simple dualistic model and even a more refined model that would distinguish between an upper entrepreneurial and a lower subsistence tier within the informal sector. However, in line with the dualistic model, the informal sector indeed fulfills a labor absorbing function in times of crisis. During the growth period authors see capital accumulation in most of the sectors and lots of evidence that households expand their activities. However, this happens mainly through the creation of new firms instead of the expansion of existing ones, which is consistent with much higher returns at very low levels of capital. More rapid expansion can be observed in sectors that operate with lower capital intensity, which is also consistent with risk or credit constraints as major deterrents to expansion. While there is some indication that total factor productivity increased over time, returns to capital and labor where not higher at the end of the observation period than at the beginning. Returns are also rather low at high levels of capital. These findings point to a limited growth potential of the informal sector as a whole. The heterogeneity in capital returns hints at large inefficiencies in allocating capital across informal firms.

    Is the Informal Sector Constrained from the Demand Side?
    (World Bank, Washington, DC, 2011-01) Bohme, Marcus; Thiele, Rainer
    Employing a unique dataset that covers households from six West African capitals, this paper provides new evidence on the demand for informal sector products and services. Authors first investigate whether demand linkages exist between formal and informal products and distribution channels. In a second step, authors estimate demand elasticity's based on Engel curves. Authors find strong demand-side linkages between the formal and informal sector, with the exception that informal goods are hardly bought through formal distribution channels. The estimated demand elasticity's tend to show that rising incomes are associated with a lower propensity to consume informal sector goods and to use informal distribution channels.

    Intergenerational Transmission of Self-Employed Status in the Informal Sector
    (World Bank, Washington, DC, 2011-04) Pasquier-Doumer, Laure
    Social reproduction is the highest for self-employed as shown by an extensive literature from developed and developing countries. Very few studies however document the reason for this high intergenerational correlation of the self-employed status. The purpose of this paper is to test if the second-generation of self-employed has an advantage related to the first-generation in the African context. It aims at highlighting the debate on firms heterogeneity in the informal sector, by identifying factors of informal business success. In addition, this paper seeks to contribute to understand the intergenerational transmission of inequalities. Using 1-2-3 surveys collected in the commercial capitals of seven West African countries in 2001-2002, this paper shows that the second-generation of informal self-employed does not have better outcomes than the first one, except when they choose a familial tradition in the same sector of activity. Thus, in the African context, having a self-employed father does not provide any advantage in terms of profit or sales and is not sufficient for the transmission of valuable skills. On the other hand, informal entrepreneurs who have chosen a specific enterprise based on familial tradition have a competitive advantage. Their competitive advantage is partly explained by the transmission of enterprise-specific human capital, acquired through experiences in the same type of activity and by the transmission of social capital that guarantees a better clientele and a reputation.

    Digital Africa
    (Washington, DC: World Bank, 2023-03-13) Begazo, Tania; Dutz, Mark Andrew; Blimpo, Moussa
    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.

    World Development Report 1994
    (New York: Oxford University Press, 1994) World Bank
    World Development Report 1994, the seventeenth in this annual series, examines the link between infrastructure and development and explores ways in which developing countries can improve both the provision and the quality of infrastructure services. In recent decades, developing countries have made substantial investments in infrastructure, achieving dramatic gains for households and producers by expanding their access to services such as safe water, sanitation, electric power, telecommunications, and transport. Even more infrastructure investment and expansion are needed in order to extend the reach of services - especially to people living in rural areas and to the poor. But as this report shows, the quantity of investment cannot be the exclusive focus of policy. Improving the quality of infrastructure service also is vital. Both quantity and quality improvements are essential to modernize and diversify production, help countries compete internationally, and accommodate rapid urbanization. The report identifies the basic cause of poor past performance as inadequate institutional incentives for improving the provision of infrastructure. To promote more efficient and responsive service delivery, incentives need to be changed through commercial management, competition, and user involvement. Several trends are helping to improve the performance of infrastructure. First, innovation in technology and in the regulatory management of markets makes more diversity possible in the supply of services. Second, an evaluation of the role of government is leading to a shift from direct government provision of services to increasing private sector provision and recent experience in many countries with public-private partnerships is highlighting new ways to increase efficiency and expand services. Third, increased concern about social and environmental sustainability has heightened public interest in infrastructure design and performance. This report includes the World Development Indicators, which offer selected social and economic statistics for 132 countries.

    Classroom Assessment to Support Foundational Literacy
    (Washington, DC: World Bank, 2025-03-21) Luna-Bazaldua, Diego; Levin, Victoria; Liberman, Julia; Gala, Priyal Mukesh
    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.

    Europe and Central Asia Economic Update, Fall 2024: Better Education for Stronger Growth
    (Washington, DC: World Bank, 2024-10-17) Izvorski, Ivailo; Kasyanenko, Sergiy; Lokshin, Michael M.; Torre, Iván
    Economic growth in Europe and Central Asia (ECA) is likely to moderate from 3.5 percent in 2023 to 3.3 percent this year. This is significantly weaker than the 4.1 percent average growth in 2000-19. Growth this year is driven by expansionary fiscal policies and strong private consumption. External demand is less favorable because of weak economic expansion in major trading partners, like the European Union. Growth is likely to slow further in 2025, mostly because of the easing of expansion in the Russian Federation and Turkiye. This Europe and Central Asia Economic Update calls for a major overhaul of education systems across the region, particularly higher education, to unleash the talent needed to reinvigorate growth and boost convergence with high-income countries. Universities in the region suffer from poor management, outdated curricula, and inadequate funding and infrastructure. A mismatch between graduates' skills and the skills employers are seeking leads to wasted potential and contributes to the region's brain drain. Reversing the decline in the quality of education will require prioritizing improvements in teacher training, updated curricula, and investment in educational infrastructure. In higher education, reforms are needed to consolidate university systems, integrate them with research centers, and provide reskilling opportunities for adult workers.

    World Development Report 1987
    (New York: Oxford University Press, 1987) World Bank
    This report, consisting of two parts, is the tenth in the annual series assessing development issues. Part I reviews recent trends in the world economy and their implications for the future prospects of developing countries. It stresses that better economic performance is possible in both industrial and developing countries, provided the commitment to economic policy reforms is maintained and reinforced. In regard to the external debt issues, the report argues for strengthened cooperation among industrial countries in the sphere of macroeconomic policy to promote smooth adjustment to the imbalances caused by external payments (in developing countries). Part II reviews and evaluates the varied experience with government policies in support of industrialization. Emphasis is placed on policies which affect both the efficiency and sustainability of industrial transformation, especially in the sphere of foreign trade. The report finds that developing countries which followed policies that promoted the integration of their industrial sector into the international economy through trade have fared better than those which insulated themselves from international competition.
