Abstract
Using a data-driven empirical case study method, the paper evaluates the impact of one identified reform program on development outcomes. The paper uses the World Bank Country Policy and Institutional Assessment Ratings to identify large scale structural and macro-level policy interventions in the last decade that were seen as being sustained and successful for IDA countries. Robustness checks are performed to show the efficacy of the method in particular cases. It was found that the method attains robustness in the case of Nigeria.

    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.

    Stanley Fischer Memorial Lecture: Geopolitics and Development—The World Bank ABCDE Conference
    (Washington, DC: World Bank, 2025-10-01) Zoellick, Robert B.
    This paper provides a sweeping historical overview of how geopolitics has shaped economic development and global institutions, culminating in a forward-looking analysis of challenges facing the world in 2025. The paper argues that understanding economic history and the political economy is essential for effective policy making, as geopolitics—encompassing power politics, geography, security, and ecology—fundamentally influences development economics. It traces the dynamic interplay between geopolitics and development across major historical periods: from the European Age of Discovery and the rise of nation-states, through the world wars and the Bretton Woods era, to the Cold War and the age of globalization. It highlights how crises and conflicts have repeatedly transformed global economic systems, spurring new ideas and institutions. Looking ahead, the paper identifies key trends for 2025—fragmented global governance amid ongoing globalization (migration, climate change, and debt), shifting security contexts with territorial disputes and nuclear risks, and the intersection of energy, climate, demographics, and migration with development—as it predicts increased economic nationalism and regionalization in finance and trade. The paper concludes by emphasizing the adaptive role of multilateral institutions like the World Bank and the International Monetary Fund, advocating for a holistic approach to development economics that integrates political and economic institutions, governance, and both macro and micro markets.

    Gender Gaps in the Performance of Small Firms: Evidence from Urban Peru
    (Washington, DC: World Bank, 2025-09-23) Celiku, Bledi; Ubfal, Diego; Valdivia, Martin
    This paper estimates the gender gap in the performance of firms in Peru using representative data on both formal and informal firms. On average, informal female-led firms have lower sales, labor productivity, and profits compared to their male-led counterparts, with differences more pronounced when controlling for observable determinants of firm performance. However, gender gaps are only significant at the bottom of the performance distribution of informal firms, and these gaps disappear at the top of the distribution of informal firms and for formal firms. Possible explanations for the performance gaps at the bottom of the distribution include the higher likelihood of small, female-led firms being home-based, which is linked to lower profits, and their concentration in less profitable sectors. The paper provides suggestive evidence that household responsibilities play a key role in explaining the gender gap in firm performance among informal firms. Therefore, policies that promote access to care services or foster a more equal distribution of household activities may reduce gender productivity gaps and allow for a more efficient allocation of resources.

    Did Higher Inequality Impede Growth in Rural China?
    (2010-11-01) Benjamin, Dwayne; Brandt, Loren; Giles, John
    This paper estimates the relationship between initial village inequality and subsequent household income growth for a large sample of households in rural China. Using a rich longitudinal survey spanning the years 1987-2002, and controlling for an array of household and village characteristics, the paper finds that households located in higher inequality villages experienced significantly lower income growth through the 1990s. However, local inequality s predictive power and effects are significantly diminished by the end of the sample. The paper exploits several advantages of the household-level data to explore hypotheses that shed light on the channels by which inequality affects growth. Biases due to aggregation and heterogeneity of returns to own-resources, previously suggested as candidate explanations for the relationship, are both ruled out. Instead, the evidence points to unobserved village institutions at the time of economic reforms that were associated with household access to higher income activities as the source of the link between inequality and growth. The empirical analysis addresses a number of pertinent econometric issues including measurement error and attrition, but underscores others that are likely to be intractable for all investigations of the inequality-growth relationship.

    Political Institutions, Inequality, and Agricultural Growth : The Public Expenditure Connection
    (World Bank, Washington, DC, 2006-04) Allcott, Hunt; Lederman, Daniel; López, Ramón
    This paper brings together the literatures on the political economy of public expenditures and the determinants of economic growth. Based on a new dataset of rural public expenditures in a panel of Latin American economies, the econometric evidence suggests that non-social subsidies reduce agricultural GDP. Furthermore, the evidence suggests that political and institutional factors as well as income inequality are determinants of the size and structure of rural public expenditures, through which they have large and significant effects on agricultural GDP.

    Reform, Growth, and Poverty in Vietnam
    (World Bank, Washington, D.C., 2002-05) Dollar, David
    Vietnam grew rapidly in the 1990s, and yet by many measures it has poor economic institutions. Dollar seeks to explain this apparent anomaly. Between the 1980s and 1990s Vietnam carried out significant economic reforms, notably stabilization, the introduction of positive real interest rates, trade liberalization, and initial property rights reform in agriculture. Relating these changes to the empirical growth literature, the author finds that Vietnam's growth acceleration is about what would be predicted. Conditional convergence also suggests that the country's high growth rate will decelerate unless further reforms are taken. The author then looks at the level of institutional and policy development in Vietnam compared with other emerging market economies. While Vietnam's policies have improved, they did so starting from a very low base. So, it can be simultaneously true that Vietnam's policies have improved a lot and yet are rather poor in comparative perspective. A comparison of governance indicators, financial sector issues, and the infrastructure of international integration reveals serious institutional weaknesses in Vietnam that need to be addressed if a high growth rate is to be sustained.

    Circumstance and Choice : The Role of Initial Conditions and Policies in Transition Economies
    (Washington, DC: World Bank, 2001-01) de Melo, Martha; Denizer, Cevdet; Gelb, Alan; Tenev, Stoyan
    This article takes an integrated approach to evaluating the interaction of initial conditions, political change, reforms and economic performance in a unified framework covering 28 transition economies in East Asia, Central and Eastern Europe, and the Former Soviet Union (FSU). Initial conditions and economic policy jointly determine the large differences in economic performance among transition economies. Initial conditions dominate in explaining inflation, but economic liberalization is the most important factor determining differences in growth. Political reform emerges as the most important determinant of the speed and comprehensiveness of economic liberalization, raising the important question of what determines political liberalization. Results suggest the importance of the level of development in determining the decision to expand political freedoms.

    Global Income Distribution and Poverty in the Absence of Agricultural Distortions
    (2009-03-01) De Hoyos, Rafael; Bussolo, Maurizio; Medvedev, Denis
    This paper assesses the potential impacts of the removal of agriculture trade distortions using a newly developed dataset and methodological approach for evaluating the global poverty and inequality effects of policy reforms. It finds that liberalization of agriculture and food could increase global extreme poverty (US$1 a day) by 0.2 percent and lower moderate poverty (US$2 a day) by 0.3 percent. Beneath these small aggregate changes, most countries witness a substantial reduction in poverty while South Asia-where half of the world's poor reside-experiences an increase in extreme poverty incidence due to high rates of protection afforded to unskilled-intensive agricultural sectors. The distributional changes are likely to be mild, but exhibit a strong regional pattern. Inequality is likely to fall in regions such as Latin America, which are characterized by high initial inequality, and rise in regions like South Asia, characterized by low initial inequality.

    Lebanon Economic Monitor, Fall 2022
    (Washington, DC, 2022-11) World Bank
    The economy continues to contract, albeit at a somewhat slower pace. Public finances improved in 2021, but only because spending collapsed faster than revenue generation. Testament to the continued atrophy of Lebanon’s economy, the Lebanese Pound continues to depreciate sharply. The sharp deterioration in the currency continues to drive surging inflation, in triple digits since July 2020, impacting the poor and vulnerable the most. An unprecedented institutional vacuum will likely further delay any agreement on crisis resolution and much needed reforms; this includes prior actions as part of the April 2022 International Monetary Fund (IMF) staff-level agreement (SLA). Divergent views among key stakeholders on how to distribute the financial losses remains the main bottleneck for reaching an agreement on a comprehensive reform agenda. Lebanon needs to urgently adopt a domestic, equitable, and comprehensive solution that is predicated on: (i) addressing upfront the balance sheet impairments, (ii) restoring liquidity, and (iii) adhering to sound global practices of bail-in solutions based on a hierarchy of creditors (starting with banks’ shareholders) that protects small depositors.

    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.

    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.
