Abstract
Measurement of food access typically relies on a consensus of different indicators. However, there is a growing list of surveys in which the Food Insecurity Experience Scale is one of the few food access indicators captured, likely because it is an official measure for tracking progress toward the Sustainable Development Goal of zero hunger. This paper uses a nationally representative, multipurpose household survey conducted in Nigeria to investigate the validity of the Food Insecurity Experience Scale. It compares the Food Insecurity Experience Scale to monetary poverty and a widely used food access metric that has been more extensively validated, the Food Consumption Score. Although it is possible for food access metrics to be poorly aligned and capture different dimensions of poor food access, empirically supported assumptions in standard consumption models result in many dimensions of poor food access being concentrated among the poorest segments of the population. However, the paper demonstrates that the Food Insecurity Experience Scale does not appear to correctly identify the population with poor food access—it finds little difference in the share with poor food access among poor and nonpoor Nigerians. Moreover, even the very richest and very poorest households have a similar prevalence of poor food access, according to the Food Insecurity Experience Scale. These patterns are in stark contrast to the Food Consumption Score, which suggests that food access is significantly lower for poorer Nigerians. Combined, the results demonstrate the importance of measuring food access with more than one indicator, and they call into question the notion of using the Food Insecurity Experience Scale alone, despite the measure being a key Sustainable Development Goal food security indicator.

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 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 Labor Demand in the Age of Generative AI: Early Evidence from the U.S. Job Posting Data(Washington, DC: World Bank, 2025-11-18)This paper examines the causal impact of generative artificial intelligence on U.S. labor demand using online job posting data. Exploiting ChatGPT’s release in November 2022 as an exogenous shock, the paper applies difference-in-differences and event study designs to estimate the job displacement effects of generative artificial intelligence. The identification strategy compares labor demand for occupations with high versus low artificial intelligence substitution vulnerability following ChatGPT’s launch, conditioning on similar generative artificial intelligence exposure levels to isolate substitution effects from complementary uses. The analysis uses 285 million job postings collected by Lightcast from the first quarter of 2018 to the second quarter of 2025Q2. The findings show that the number of postings for occupations with above-median artificial intelligence substitution scores fell by an average of 12 percent relative to those with below-median scores. The effect increased from 6 percent in the first year after the launch to 18 percent by the third year. Losses were particularly acute for entry-level positions that require neither advanced degrees (18 percent) nor extensive experience (20 percent), as well as those in administrative support (40 percent) and professional services (30 percent). Although generative artificial intelligence generates new occupations and enhances productivity, which may increase labor demand, early evidence suggests that some occupations may be less likely to be complemented by generative artificial intelligence than others.Publication The Lasting Effects of Working while in School(Washington, DC: World Bank, 2025-08-18)This paper provides the first experimental evidence on the long-term effects of work-study programs, leveraging a randomized lottery design from a national program in Uruguay. Participation leads to a persistent 11 percent increase in formal labor earnings, observable seven years after the program. Effects are stronger for youth who participate during pivotal educational transitions and are larger for vulnerable youth and men, while remaining positive for women and non-vulnerable youth. The program is highly cost-effective, with average impacts exceeding those of job training programs and comparable to early childhood investments.Publication It’s Not (Just) the Tariffs: Rethinking Non-Tariff Measures in a Fragmented Global Economy(Washington, DC: World Bank, 2025-10-22)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.

Publication How Much Does the Food Insecurity Experience Scale Overlap with Poor Food Consumption and Monetary Poverty? Evidence from West Africa(Published by Oxford University Press on behalf of the World Bank, 2023-10-12)The Food Insecurity Experience Scale (FIES), which combines three food-access dimensions into a single indicator, is rapidly being incorporated into national statistical systems. However, there is no prediction about how one of the incorporated dimensions, subjective experiences associated with food insecurity, overlaps with poor food consumption. Using data from West Africa, this study illustrates that in 4 out of 10 countries, there is a similar prevalence of food insecurity according to the FIES among segments of the population that are likely undernourished and segments that are likely not undernourished. And in 5 out of 10 countries, there is a relatively large prevalence of food insecurity according to the FIES in the segments of the population that are least likely to be undernourished. Combined, the results offer guidance to policymakers when choosing food-access indicators and illustrate the importance of using the FIES along with other food-access measures.Publication Evolution of Poor Food Access over the Course of the Conflict in the Republic of Yemen(World Bank, Washington, DC, 2019-04)The Republic of Yemen has undergone a profound transformation following the escalation of conflict in March 2015. There has been an increase in violence, a disruption in supply chains due to a tightening of the ports, and a decline in the general economic climate that has left a large share of the population without the income to support their basic needs. These transformations have resulted in widespread food insecurity, where nearly half the population is under the threat of a potential famine. Although the violence has undeniably had a significant impact on the population and local outcomes, the temporal and regional distribution of poor food access suggest that food insecurity of the mobile phone–using population has been primarily driven by factors aside from the localized effects of violence alone. The lack of a strong relationship between violence and poor welfare outcomes contrasts with evidence from other conflict settings, and further contrasts with the rationale underpinning much of the humanitarian and development assistance currently being delivered in the country.Publication Assessing Food Insecurity in Latin America and the Caribbean Using FAO’s Food Insecurity Experience Scale(Elsevier, 2017-08)The complexity of the operational concept and definition of food insecurity has complicated the study of the ‘food insecure’ and efforts to determine clear policy directions. Previous findings on the prevalence and severity of food insecurity are inconsistent and often depend on the measure used. To overcome limitations in food security measurement, the Food and Agriculture Organization of the United Nations developed the Food Insecurity Experience Scale, which is the first survey protocol to measure people’s direct experience of food insecurity on a global scale. Using this new measure, our study contributes to the understanding of the food insecure by examining the determinants of food insecurity within and across countries in Latin America and the Caribbean (LAC). Using a series of multilevel linear models, we find the three determinants associated with the largest increase in the likelihood of experiencing food insecurity in LAC are: low levels of education, limited social capital, and living in a country with low GDP per capita. Results suggest the need to promote education of the most vulnerable, encourage social interactions that help build individuals’ social capital, and adopt gender-sensitive programs. The results also suggest the need for a shift in policy from short-term strategies to long-term efforts that sustain household productive capacity and employment to promote sustained economic growth.Publication Anticipating Large and Widespread Seasonal Deprivation in the Sahel(Washington, DC : World Bank, 2021-11)In addition to being regularly confronted with unpredictable shocks such as floods, droughts, or conflicts, Sahelian households have to deal with the effects of seasonality. This leads to a significant reduction in food and non-food consumption across the season, exposing the poor to transient food insecurity and malnutrition.Publication Famine and the Aid Response(World Bank, Washington, DC, 2019-04)Using a high-frequency mobile phone survey of food security conducted by the World Food Programme, this paper investigates how food assistance and access to food changed following the announcement of famine-like conditions in the Republic of Yemen. Among the mobile phone–using population, the share of households receiving food assistance more than doubled following the announcement. The increases were largely targeted at regions identified in the announcement as being closer to famine in the original announcement, and there was improvement in access to food in regions that received the most food assistance relative to the rest of the country. Although the survey misses struggling households that do not have access to a mobile phone and are potentially more at risk of famine, the results raise questions about the need for better quality data in food emergencies that are updated more regularly for better targeting of food assistance.

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.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 Europe and Central Asia Economic Update, Spring 2025: Accelerating Growth through Entrepreneurship, Technology Adoption, and Innovation(Washington, DC: World Bank, 2025-04-23)Business dynamism and economic growth in Europe and Central Asia have weakened since the late 2000s, with productivity growth driven largely by resource reallocation between firms and sectors rather than innovation. To move up the value chain, countries need to facilitate technology adoption, stronger domestic competition, and firm-level innovation to build a more dynamic private sector. Governments should move beyond broad support for small- and medium-sized enterprises and focus on enabling the most productive firms to expand and compete globally. Strengthening competition policies, reducing the presence of state-owned enterprises, and ensuring fair market access are crucial. Limited availability of long-term financing and risk capital hinders firm growth and innovation. Economic disruptions are a shock in the short term, but they provide an opportunity for implementing enterprise and structural reforms, all of which are essential for creating better-paying jobs and helping countries in the region to achieve high-income status.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.
