Abstract
This paper has three primary objectives: (i) to investigate potential problems regarding Mozambique's most recent nationally representative household survey on poverty dynamics; (ii) to assess the robustness and reliability of official poverty statistics; and (iii) to provide alternative estimates of poverty and welfare indicators in light of the methodological and analytical issues raised in areas (i) and (ii). It is determined that at least two significant weaknesses affect the official poverty-rate estimates: measurement errors in consumption data and flaws in the methodology used to calculate poverty lines (the cost-of-basic-needs approach based on provincial food bundles with entropy correction). A number of observations appear to be affected by substantial measurement errors, which severely distort the official poverty statistics. The paper provides methods to correct the consumption distribution by recalculating poverty lines based on a single national food basket -- as opposed to the current estimates, which are based on province-specific food baskets. The revised poverty statistics differ considerably from the official estimates of poverty across provinces and are far more consistent with other poverty indicators. In addition, poverty appears to be highly concentrated in certain areas, with dramatically higher rates found in Central and Northern Mozambique, as well as in rural areas overall, compared with relatively low rates in Southern Mozambique and in the country's urban centers. These findings substantially contradict the government's official poverty figures, which appear to systematically overestimate poverty rates in Mozambique's Southern provinces and urban areas while simultaneously underestimating the prevalence of poverty in the country's Central and Northern regions and in rural areas nationwide.

Publication Global Poverty Revisited Using 2021 PPPs and New Data on Consumption(Washington, DC: World Bank, 2025-06-05)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.Publication The Economic Value of Weather Forecasts: A Quantitative Systematic Literature Review(Washington, DC: World Bank, 2025-09-10)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.Publication The Marshall Plan: Then and Now(Washington, DC: World Bank, 2025-10-14)This paper is a product of the Development Policy Team, Development Economics. It is part of a larger effort by the World Bank to provide open access to its research and make a contribution to development policy discussions around the world.

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 Geopolitical Risks and Trade(Washington, DC: World Bank, 2025-09-23)This paper studies the impact of geopolitical risks on international trade, using the Geopolitical Risk (GPR) index of Caldara and Iacoviello (2022) and an empirical gravity model. The impact of spikes in geopolitical risk on trade is negative, strong, and heterogeneous across sectors. The findings show that increases in geopolitical risk reduce trade by about 30 to 40 percent. These effects are equivalent to an increase of global tariffs of up to 14 percent. Services trade is most vulnerable to geopolitical risks, followed by agriculture, and the impact on manufacturing trade is moderate. These negative effects are partially mitigated by cultural and geographic proximity, as well as by the presence of trade agreements.

Publication Measurements of Poverty in Indonesia : 1996, 1999, and Beyond(World Bank, Washington, DC, 2000-09)Indonesia's economic crisis has caused a consumption expenditures deterioration in the welfare of Indonesians. Focusing on only one dimension of individual, and family welfare - consumption expenditures - the authors analyze two issues associated with the measurement of poverty. The first issue is how to produce regionally consistent poverty lines - that is, how to define a level of spending for each region that produces the same material standard of living. Without comparable data on prices, there is a problem of circularity. Choosing the reference population is important for defining the price level by which to deflate money expenditures to reach the same welfare level, but one needs to know the price level to define the reference population as a group with the same real expenditures. To address the problem of circularity, the authors use an iterative approach to defining poverty, one that produces consistent results across regions. They then use those poverty lines to examine the common "poverty profiles" (by location, sector, and so on). The second issue is more conceptual: how to expand the narrow measure of poverty, based on spending for consumption, with extensions that expand how welfare is measured, and allow more consistent comparisons of different individuals' welfare levels.Publication Poverty Status in Afghanistan(World Bank, Washington, DC, 2010-07)Poverty reduction is one of the three key objectives of the Afghanistan national development strategy. The poverty profile is an important element in the information kit of the policymaker that helps focus policy to attain this objective. A poverty profile is standard methodology to describe the extent and nature of poverty in a country or region. It assesses the magnitude of poverty and its distribution across geographic and socioeconomic domains, provides information on the characteristics of the poor, illustrates the heterogeneity among the poor, and identifies correlates of poverty. The report describes the multidimensional nature of poverty by encompassing the nonmonetary dimensions of poverty, particularly education and health status, and vulnerability to shocks. Tables in the report are also disaggregated by region, income sources, gender, and many socioeconomic characteristics. In addition to providing a picture of the many dimensions of poverty, it is important to also recognize that the poverty estimates in this report are the first nationally representative, seasonally smoothed estimates of wellbeing for Afghanistan. Because previously no such existing estimates were available, the provision of these estimates in this report is new analysis that substantially fills key knowledge gaps in our understanding of the poverty situation in Afghanistan.Publication Argentina : Poor People in a Rich Country, Volume 2. Background Papers(Washington, DC, 2000-04-14)The study presents an overview on Argentina's economic growth, income distribution, and poverty, mostly as of 1991, when the country underwent a period of adjustment, which remarkably led to a sharp inflation drop, to the privatization of state-owned industries, and to fostering foreign commerce, thus widening the economy. Nonetheless, the study points out that all of these adjustments affected the poor, particularly through labor demand, exacerbated by the slowdown of the growth process, resulting from the economic crises of 1995, and 1998. Recommendations include macroeconomic, and reform policies to allow rapid growth, and stabilize the economy, without inflation, for a substantial poverty reduction. The elimination of centralized, collective bargaining labor agreements, reduction of labor taxes, and severance payments, would prod a funded, unemployment insurance system, based on individual accounts, and thus, reduce the high cost of labor. Temporary employment, and extended programs should not be enforced under payroll taxes, to allow exceptions for small scale enterprise development. Accessibility of the poor to basic services should be enhanced, mainly through greater investments in education, and health care services. In addition, a strong system of safety nets is recommended, through the identification of expanding programs, to also provide emergency employment, and income during potential crises.Publication The Distributional Impacts of Indonesia's Financial Crisis on Household Welfare : A 'Rapid Response' Methodology(Washington, DC: World Bank, 2002-09)Analyzing the distributional impacts of economic crises is an ever more pressing need. If policymakers are to intervene to help those most adversely affected, they need to identify those who have been hurt most and estimate the magnitude of the harm they have suffered. They must also respond in a timely manner. This article develops a simple methodology for measuring these effects and applies it to analyze the impact of the Indonesian economic crisis on household welfare. Using only pre-crisis household information, it estimates the compensating variation for Indonesian households following the 1997 Asian currency crisis and then explores the results with flexible nonparametric methods. It finds that virtually every household was severely affected, although the urban poor fared the worst. The ability of poor rural households to produce food mitigated the worst consequences of the high inflation. The distributional consequences are the same whether or not households are permitted to substitute toward relatively cheaper goods. Households with young children may have suffered disproportionately large adverse effects.Publication Poverty Lines across the World(2010-04-01)National poverty lines vary greatly across the world, from under $1 per person per day to over $40 (at 2005 purchasing power parity). What accounts for these huge differences, and can they be understood within a common global definition of poverty? For all except the poorest countries, the absolute, nutrition-based, poverty lines found in practice tend to behave more like relative lines, in that they are higher for richer countries. Prevailing methods of setting absolute lines allow ample scope for such relativity, even when nutritional norms are common across countries. Both macro data on poverty lines across the world and micro data on subjective perceptions of poverty are consistent with a weak form of relativity that combines absolute consumption needs with social-inclusion needs that are positive for the poorest but rise with a country s mean consumption. The strong form of relativism favored by some developed countries -- whereby the line is set at a fixed proportion of the mean -- emerges as the limiting case for very rich countries.

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 Digital Africa(Washington, DC: World Bank, 2023-03-13)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.Publication World Development Report 2006(Washington, DC, 2005)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.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 Morocco Economic Update, Winter 2025(Washington, DC: World Bank, 2025-04-03)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.
