Abstract
This paper uses 1-2-3 survey data on the Democratic Republic of Congo to analyze heterogeneity in the informal sector. It empirically identifies three types of entrepreneurs in the sector. The first group of entrepreneurs—top performers -- is growth oriented and enjoys greater access to capital. The second group—constrained gazelles -- includes entrepreneurs who share many characteristics, especially management skills, with the top performers, but operate with less capital. The third group—survivalists—comprises firms struggling to grow. Based on logit and fixed effect ordinary least squares models, the results presented in this paper show that poverty and income inequality are more common among constrained gazelles and survivalists. The paper also shows that income inequality is explained mainly by educational disparities and lack of credit access among entrepreneurs. Additionally, the outcomes of a Blinder-Oaxaca decomposition show that the performance of firms is a key factor in explaining differences in income. Examining the drivers of performance, the paper finds that human capital and managerial skills are important engines of performance.

    Global Poverty Revisited Using 2021 PPPs and New Data on Consumption
    (Washington, DC: World Bank, 2025-06-05) Foster, Elizabeth; Jolliffe, Dean Mitchell; Lara Ibarra, Gabriel; Lakner, Christoph; Tettah-Baah, Samuel
    Recent improvements in survey methodologies have increased measured consumption in many low- and lower-middle-income countries that now collect a more comprehensive measure of household consumption. Faced with such methodological changes, countries have frequently revised upward their national poverty lines to make them appropriate for the new measures of consumption. This in turn affects the World Bank’s global poverty lines when they are periodically revised. The international poverty line, which is based on the typical poverty line in low-income countries, increases by around 40 percent to $3.00 when the more recent national poverty lines as well as the 2021 purchasing power parities are incorporated. The net impact of the changes in international prices, the poverty line, and new survey data (including new data for India) is an increase in global extreme poverty by some 125 million people in 2022, and a significant shift of poverty away from South Asia and toward Sub-Saharan Africa. The changes at higher poverty lines, which are more relevant to middle-income countries, are mixed.

    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.

    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.

    It’s Not (Just) the Tariffs: Rethinking Non-Tariff Measures in a Fragmented Global Economy
    (Washington, DC: World Bank, 2025-10-22) Taglioni, Daria; KEE, Hiau Looi
    As tariffs have declined, non-tariff measures (NTMs) have become central to trade policy, especially in high-income countries and regulated sectors like food and green technologies. Although NTMs may serve legitimate goals, they could also sort countries and firms into or out of markets based on compliance capacity and differences in product mix. Documenting recent advances in the estimation of ad valorem equivalents (AVEs), this paper uncovers new patterns of use and exposure of NTMs. High-income countries rely more heavily on NTMs relative to tariffs, while low- and middle-income countries face steeper AVEs on their exports. Firm-level evidence shows that NTMs disproportionately affect smaller firms, leading to market exit and concentration. Poorly designed NTMs can harm productivity and welfare, while coordinated, capacity-aware use can deliver inclusive outcomes. Policy design, transparency, and diagnostics must evolve to reflect the growing role—and risks—of NTMs in a fragmented global trade landscape.

    Industrial Clusters and Micro and Small Enterprises in Africa : From Survival to Growth
    (World Bank, 2011) Yoshino, Yutaka
    The private sector is the engine of economic growth, stimulating entrepreneurship and innovation and promoting competition and productivity. While many countries in Africa have developed private sector-driven growth strategies, private investment as a proportion of gross domestic product (GDP) is only 13 percent in Africa, significantly lower than in other regions, such as South Asia, with many low-income countries. The public sector still occupies the lion's share of economic activity in Africa. This study addresses how industrial clusters could be a springboard for the development of Africa's micro and small enterprise sector, which constitutes the bulk of the region's indigenous private sector. The successful development of industrial clusters in Asia illustrates how small enterprises can help to drive growth led by market expansion at home and abroad.

    The Impact of Consulting Services on Small and Medium Enterprises : Evidence from a Randomized Trial in Mexico
    (World Bank, Washington, DC, 2013-06) Karlan, Dean; Schoar, Antoinette; Bruhn, Miriam
    Using a randomized evaluation with 432 Mexican small and medium enterprises, this paper shows that access to management consulting led to better firm performance: one-year results show positive effects on return-on-assets and total factor productivity. Owners also had large increases in "entrepreneurial spirit" (an entrepreneurs' managerial confidence index). Using Mexican social security data, the analysis finds a large increase in the number of employees and total wage bill several years after the program. The paper documents large heterogeneity in the specific managerial practices that improved as a result of the consulting, but there is no singular mechanism as a panacea for all firms.

    Access to Finance, Product Innovation and Middle-Income Traps
    (World Bank, Washington, DC, 2014-02) Agénor, Pierre-Richard; Canuto, Otaviano
    This paper studies interactions between access to finance, product innovation, and labor supply in a two-period overlapping generations model with an endogenous skill distribution and credit market frictions. In the model lack of access to finance (induced by high monitoring costs) has an adverse effect on innovation activity not only directly but also indirectly, because too few individuals may choose to invest in skills. If monitoring costs fall with the number of successful projects, multiple equilibria may emerge, one of which, a middle-income trap, characterized by low wages in the design sector, a low share of the labor force engaged in innovation activity, and low growth. A sufficiently ambitious policy aimed at alleviating constraints on access to finance by innovators may allow a country to move away from such a trap by promoting the production of ideas and improving incentives to invest in skills.

    Inclusive Growth Analysis in Economies Prone to International Migration
    (World Bank, Washington, DC, 2011-09) Keller, Jennifer; Scheja, Elina
    Inclusive growth (IG) analysis involves analyzing the available data in a country to determine the best course of action for accelerating growth and or improving the distribution of the opportunities and benefits from the growth process. In economies in which international migration is a significant trend, that determination may be especially challenging. The international migration phenomenon can contribute to (or detract from) growth and its distribution through myriad number of complex and sometimes divergent channels, and these effects can change substantially over time. The ability to analyze these impacts, however, is often significantly handicapped by a lack of appropriate data. Moreover, because the migration decision is inherently a private decision made by households in the best interest of their welfare, determining the policy conclusions based on the results of inclusive growth analysis is often unclear. Governments are rightfully wary of interfering with the migration process. This paper examines the issue of international migration in inclusive growth. The aim is to provide the practitioners of inclusive growth diagnostics a useful framework for assessing the nature of the international migration phenomenon, and to highlight the key tools utilized in evaluating its current and potential impact on shared growth.

    Leading Dragons Phenomenon : New Opportunities for Catch-Up in Low-Income Countries
    (2012-03-01) Chandra, Vandana; Lin, Justin Yifu; Wang, Yan
    Modern economic development is accompanied by the structural transformation from an agrarian to an industrial economy and occurs through a process of continuous industrial and technological upgrading. Since the 18th century, all countries that industrialized successfully in Europe, North America and East Asia followed their comparative advantage and leveraged the late-comer advantage to emulate the leader-follower flying geese pattern of industrial upgrading. The large dynamic emerging market countries such as China, India and Brazil are also engaged in industrial upgrading but with a critical difference. In particular, because of its sheer size, China has absorbed nearly all labor-intensive jobs and become the world s largest exporter of labor-intensive products. The current view is that China s dominance hinders poor countries from developing similar industries. The authors argue that industrial upgrading has increased wages and is causing China to graduate from labor-intensive to more capital- and technology-intensive industries. These industries will shed labor and create a huge opportunity for lower wage countries to start a phase of labor-intensive industrialization. This process, called the Leading Dragon Phenomenon, offers an unprecedented opportunity to low-income Sub-Saharan Africa where the industrial sector is underdeveloped and investment capital and entrepreneurial skills are leading constraints to manufacturing. It can seize the opportunity and resolve the constraints by attracting some of the OFDI flowing currently from China, India and Brazil into the manufacturing sectors of other developing countries. All low-income countries will compete but to catch the jobs spillover from China, the winner must implement credible economic development strategies that are consistent with its comparative advantage.

    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.

    Morocco Economic Update, Winter 2025
    (Washington, DC: World Bank, 2025-04-03) World Bank
    Despite the drought causing a modest deceleration of overall GDP growth to 3.2 percent, the Moroccan economy has exhibited some encouraging trends in 2024. Non-agricultural growth has accelerated to an estimated 3.8 percent, driven by a revitalized industrial sector and a rebound in gross capital formation. Inflation has dropped below 1 percent, allowing Bank al-Maghrib to begin easing its monetary policy. While rural labor markets remain depressed, the economy has added close to 162,000 jobs in urban areas. Morocco’s external position remains strong overall, with a moderate current account deficit largely financed by growing foreign direct investment inflows, underpinned by solid investor confidence indicators. Despite significant spending pressures, the debt-to-GDP ratio is slowly declining.

    World Development Report 2006
    (Washington, DC, 2005) World Bank
    This year’s Word Development Report (WDR), the twenty-eighth, looks at the role of equity in the development process. It defines equity in terms of two basic principles. The first is equal opportunities: that a person’s chances in life should be determined by his or her talents and efforts, rather than by pre-determined circumstances such as race, gender, social or family background. The second principle is the avoidance of extreme deprivation in outcomes, particularly in health, education and consumption levels. This principle thus includes the objective of poverty reduction. The report’s main message is that, in the long run, the pursuit of equity and the pursuit of economic prosperity are complementary. In addition to detailed chapters exploring these and related issues, the Report contains selected data from the World Development Indicators 2005‹an appendix of economic and social data for over 200 countries. This Report offers practical insights for policymakers, executives, scholars, and all those with an interest in economic development.

    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.

    Argentina Country Climate and Development Report
    (World Bank, Washington, DC, 2022-11) World Bank Group
    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.
