Abstract
The availability of weather data from remotely sensed Earth observation data has reduced the cost of including weather variables in econometric models. Weather variables are common instrumental variables used to predict economic outcomes and serve as an input in modeling crop yields for rainfed agriculture. The use of Earth observation data in econometric applications has only recently been met with critical assessment of the suitability and quality of these data in economics. This paper quantifies the significance and magnitude of the effect of measurement error in Earth observation data in the context of smallholder agricultural productivity. The paper shows that different Earth observation sources use different measurement methods. The findings are not robust to the choice of Earth observation dataset, and the outcomes are not simply affine transformations of one another. Thus, the paper suggests that researchers should exercise caution in using these data and include robustness checks that test alternative sources of Earth observation data.

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 Geopolitics and the World Trading System(Washington, DC: World Bank, 2024-12-23)Until the beginning of this century, the GATT/WTO system worked. Economic research provided a compelling explanation. It showed that if governments maximize the well-being of their own countries broadly defined, GATT/WTO principles would facilitate mutually beneficial cooperation over their trade policy choices. Now heightened geopolitical rivalry seems to have undermined the WTO. A simple transposition of the previous rationalization suggests that geopolitics and trade cooperation are not compatible. The paper shows that this is only true if rivalry eclipses any consideration of own-country well-being. In all other circumstances, there are gains from trade cooperation even with geopolitics. Furthermore, the WTO’s relevance is in question only if it adheres too rigidly to its existing rules and norms. Through measured adaptation to the geopolitical imperative, the WTO can continue to thrive as a forum for multilateral trade cooperation in the age of geopolitics.Publication From Patriarchy to Policy(Washington, DC: World Bank, 2025-05-29)Legal institutions play an important role in shaping gender equality in economic domains, from inheritance to labor markets. But where do gender equal laws come from? Using cross-country data on social norms and legal equality, this paper investigates the socio-cultural roots of gender inequity in the legal system and its implications for female labor force participation. To identify the impact of social norms, the analysis uses an empirical strategy that exploits pre-modern differences in ancestral patriarchal culture as an instrument for present-day gender norms. The findings show that ancestral patriarchal culture is a strong predictor of contemporary norms, and conservative social norms are associated with more gender inequality in the de jure legal framework, the de facto implementation of laws, and the labor market. The paper presents evidence for a political selection mechanism linking norms to laws: countries with more conservative norms elect political leaders who are more hostile to gender equality, who then pass less progressive legislation. The results highlight the cultural roots and political drivers of legalized gender inequality.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 Rethinking Fiscal Policies(Washington, DC: World Bank, 2025-05-27)This paper examines the redistributive impact of fiscal policy—specifically taxes and transfers—on poverty and inequality in eight countries in the Middle East and North Africa: the Arab Republic of Egypt, Djibouti, the Islamic Republic of Iran, Iraq, Jordan, Morocco, Tunisia, and the West Bank and Gaza. Utilizing the Commitment to Equity framework, the analysis evaluates how fiscal interventions alter income distribution across these diverse national contexts. The results indicate that direct cash transfers and social assistance programs are generally effective in reducing poverty and shielding vulnerable populations, while in-kind benefits—particularly in education and healthcare—significantly contribute to mitigating income inequality. In contrast, generalized subsidies, especially in the energy sector, are fiscally burdensome and largely regressive, offering limited equity gains. Indirect taxes, although important for revenue generation, often exacerbate income disparities. The study underscores the need for comprehensive fiscal reforms, including the expansion of well-targeted transfers, adoption of progressive taxation, and reallocation of inefficient subsidies toward investments in human capital. Successful initiatives, such as Egypt’s Takaful and Karama and Jordan’s Takaful and bread subsidy compensation programs, illustrate scalable models of effective redistribution. Moreover, the Islamic Republic of Iran’s progressive tax policies highlight viable pathways to equitable revenue mobilization. Strengthening investment in education and health is essential for promoting long-term equity, enhancing upward mobility, and supporting inclusive and sustainable development across the region.

Publication Estimating the Impact of Weather on Agriculture(World Bank, Washington, DC, 2021-11)This paper quantifies the significance and magnitude of the effect of measurement error in remote sensing weather data in the analysis of smallholder agricultural productivity. The analysis leverages 17 rounds of nationally-representative, panel household survey data from six countries in Sub-Saharan Africa. These data are spatially linked with a range of geospatial weather data sources and related metrics. The paper provides systematic evidence on measurement error introduced by (1) different methods used to obfuscate the exact GPS coordinates of households, (2) different metrics used to quantify precipitation and temperature, and (3) different remote sensing measurement technologies. First, the analysis finds no discernible effect of measurement error introduced by different obfuscation methods. Second, it finds that simple weather metrics, such as total seasonal rainfall and mean daily temperature, outperform more complex metrics, such as deviations in rainfall from the long-run average or growing degree days, in a broad range of settings. Finally, the analysis finds substantial amounts of measurement error based on remote sensing products. In extreme cases, the data drawn from different remote sensing products result in opposite signs for coefficients on weather metrics, meaning that precipitation or temperature drawn from one product purportedly increases crop output while the same metrics drawn from a different product purportedly reduces crop output. The paper concludes with a set of six best practices for researchers looking to combine remote sensing weather data with socioeconomic survey data.Publication Coping or Hoping?: Livelihood Diversification and Food Insecurity in the COVID-19 Pandemic(Washington, DC: World Bank, 2025-01-07)This paper examines the impact of livelihood diversification on food insecurity amid the COVID-19 pandemic. The analysis uses household panel data from Ethiopia, Malawi, and Nigeria in which the first round was collected immediately prior to the pandemic and extends through multiple rounds of monthly data collection during the pandemic. Using this pre- and post-outbreak data, and guided by a pre-analysis plan, the paper estimates the causal effect of livelihood diversification on food insecurity. The results do not support the hypothesis that livelihood diversification boosts household resilience. Although income diversification may serve as an effective coping mechanism for small-scale shocks, the findings show that for a disaster on the scale of the pandemic, this strategy is not effective. Policy makers looking to prepare for the increased occurrence of large-scale disasters will need to grapple with the fact that coping strategies that gave people hope in the past may fail them as they try to cope with the future.Publication Understanding the Requirements for Surveys to Support Satellite-Based Crop Type Mapping(World Bank, Washington, DC, 2021-04)With the surge in publicly available high-resolution satellite imagery, satellite-based monitoring of smallholder agricultural outcomes is gaining momentum. This paper provides recommendations on how large-scale household surveys should be conducted to generate the data needed to train models for satellite-based crop type mapping in smallholder farming systems. The analysis focuses on maize cultivation in Malawi and Ethiopia, and leverages rich, georeferenced plot-level data from national household surveys that were conducted in 2018–20 and that are integrated with Sentinel-2 satellite imagery and complementary geospatial data. To identify the approach to survey data collection that yields optimal data for training remote sensing models, 26,250 in silico experiments are simulated within a machine learning framework. The best model is then applied to map seasonal maize cultivation from 2016 to 2019 at 10-meter resolution in both countries. The analysis reveals that smallholder plots with maize cultivation can be identified with up to 75 percent accuracy. However, the predictive accuracy varies with the approach to georeferencing plot locations and the number of observations in the training data. Collecting full plot boundaries or complete plot corner points provides the best quality of information for model training. Classification performance peaks with slightly less than 60 percent of the training data. Seemingly small erosion in accuracy under less preferable approaches to georeferencing plots results in total area under maize cultivation being overestimated by 0.16 to 0.47 million hectares (8 to 24 percent) in Malawi.Publication The Evolving Socioeconomic Impacts of COVID-19 in Four African Countries(World Bank, Washington, DC, 2021-03)The paper provides evidence on the evolving socioeconomic impacts of the COVID-19 pandemic among households in Ethiopia, Malawi, Nigeria, and Uganda. The data allow estimating the immediate economic impacts of the pandemic, beginning in April 2020, and tracking how the situation evolved through September 2020. Although households have started to see recovery in income, business revenues, and food security, the gains have been relatively modest. Additionally, households have received very little outside assistance and their ability to cope with shocks remains limited. School closures have created a vacuum in education delivery and school-aged children have struggled to receive education services remotely.Publication Socioeconomic Impacts of COVID-19 in Four African Countries(World Bank, Washington, DC, 2020-11)The coronavirus disease 2019 (COVID-19) and the attempts to limit its spread have resulted in profound economic impacts, and a significant contraction in the global economy is expected. This paper provides some of the first evidence on the socioeconomic impacts of and responses to the pandemic among households and individuals in Sub-Saharan Africa. To do so, reduced-form econometric methods are applied to longitudinal household survey data from Ethiopia, Malawi, Nigeria, and Uganda -- originating from the pre-COVID-19 face-to-face household surveys and from the novel phone surveys that are being implemented during the pandemic. The headline findings are fourfold. First, although false beliefs about COVID-19 remain prevalent, government action to limit the spread of the disease is associated with greater individual knowledge of the disease and increased uptake of precautionary measures. Second, 256 million individuals -- 77 percent of the population in the four countries -- are estimated to live in households that have lost income due to the pandemic. Third, attempts to cope with this loss are exacerbated by the inability to access medicine and staple foods among 20 to 25 percent of the households in each country, and food insecurity is disproportionately borne by households that were already impoverished prior to the pandemic. Fourth, student-teacher contact has dropped from a pre-COVID-19 rate of 96 percent to just 17 percent among households with school-age children. These findings can help inform decisions by governments and international organizations on measures to mitigate the effects of the COVID-19 pandemic and reveal the need for continued monitoring.

Publication Global Economic Prospects, January 2025(Washington, DC: World Bank, 2025-01-16)Global growth is expected to hold steady at 2.7 percent in 2025-26. However, the global economy appears to be settling at a low growth rate that will be insufficient to foster sustained economic development—with the possibility of further headwinds from heightened policy uncertainty and adverse trade policy shifts, geopolitical tensions, persistent inflation, and climate-related natural disasters. Against this backdrop, emerging market and developing economies are set to enter the second quarter of the twenty-first century with per capita incomes on a trajectory that implies substantially slower catch-up toward advanced-economy living standards than they previously experienced. Without course corrections, most low-income countries are unlikely to graduate to middle-income status by the middle of the century. Policy action at both global and national levels is needed to foster a more favorable external environment, enhance macroeconomic stability, reduce structural constraints, address the effects of climate change, and thus accelerate long-term growth and development.Publication The Markets and Competition Policy Assessment Toolkit(Washington, DC: World Bank, 2025-01-09)The markets and competition policy assessment toolkit (MCPAT) is a guide for understanding how policy can positively shape markets and address market failures that ultimately affect micro- and macroeconomic development issues. The MCPAT aims to support policymakers, competition authorities, and development finance institutions in realizing the advantages of competitive and well-functioning markets by setting the right conditions for firms to improve their economic performance and for markets to allocate resources efficiently. Competitive and well-functioning markets do not just benefit consumers, - they benefit entire economies as they promote productivity, innovation, efficiency, and consumer choice. The goal is not simply to increase the number of firms in a market or to restrict market power but to create an environment where competition can thrive, firms can innovate, and markets can function optimally. The structure of this toolkit follows the steps to conduct an MCPAT analysis in a specific sector or market. Part I provides an overview of key concepts that set the basis for conducting the MCPAT analysis and covers the first step of the MCPAT. Part II focuses on diagnosing market issues. Part III is about how to fix markets.Publication Poverty and Equity Assessment for El Salvador 2024(Washington, DC: World Bank, 2024-12-12)This report proposes an agenda for building on gains to re-accelerate poverty reduction among Salvadorans. The last World Bank Poverty Assessment for El Salvador, from 2015, proposed two key policy recommendations: (a) effective pro-poor spending and (b) reduction of crime and violence through better access to jobs and education. Nine years later, the authorities have managed to achieve a substantial reduction in crime and violence and have indicated an intent to build on such progress to establish a path toward an El Salvador where shared prosperity is achievable. In this report, we propose a three pillar structure to address poverty and inequality reduction: jobs, services, and social protection, with a cross-cutting set of primary conditions that articulates this structure.Publication Services Unbound(Washington, DC: World Bank, 2024-12-09)Services are a new force for innovation, trade, and growth in East Asia and Pacific. The dramatic diffusion of digital technologies and partial policy reforms in services--from finance, communication, and transport to retail, health, and education--is transforming these economies. The result is higher productivity and changing jobs in the services sector, as well as in the manufacturing sectors that use these services. A region that has thrived through openness to trade and investment in manufacturing still maintains innovation-inhibiting barriers to entry and competition in key services sectors. 'Services Unbound: Digital Technologies and Policy Reform in East Asia and Pacific' makes the case for deeper domestic reforms and greater international cooperation to unleash a virtuous cycle of increased economic opportunity and enhanced human capacity that would power development in the region.Publication At Your Service?: The Promise of Services-led Growth in Uzbekistan(Washington, DC: World Bank, 2025-01-07)In Uzbekistan, the services sector accounts for more than half of all jobs and has been central to the process of structural transformation over the past three decades. In the past decade, the growth of Uzbekistan’s services exports has lagged behind its manufactures' exports while FDI greenfield announcements to both sectors have been even. The growth of the services sector in the past five years was driven by social services, mostly reflecting increased public spending. This report groups the services sector into four categories based on their skill intensity, the extent of their linkages with other sectors, and their tradability in international markets: low-skilled consumer services, low-skilled enabling services , global innovator services. Of these groups, social services accounted for three-fourths of employment growth in the services sector between 2017–2022. These services also experienced relatively high rates of labor productivity growth, which was largely driven by higher public spending on wages and salaries.
