The World Bank Research Observer seeks to inform readers about research from both within and outside the World Bank, in areas of economics relevant for development policy. Requiring only a minimal background in economic analysis, its surveys and overviews of key issues in development economics research are intended for policymakers, project officers, professors and students of development economics and related disciplines, nonspecialists, and journalists keeping up to date.
Papers for the Observer are not sent out to referees, but all articles published are assessed and approved by the Editorial Board, which includes three to four distinguished economists from outside the Bank.

Publication Land Policies and Institutions for Equitable and Resilient Growth in Africa(Oxford University Press on behalf of the World Bank, 2025-01-24) Deininger, Klaus; Goyal, AparajitaIn coming decades, Africa's urban populations will expand, and the effects of climate change be more keenly felt. Land policies and institutions will be key for urban dwellers to be able access productive jobs, breathe clean air, and live in decent housing; for entrepreneurs, especially women, to leverage land for productive investment; and for farmers to diversify, insure against shocks, and accumulate capital. Yet, many African land registries perform poorly, command little trust, and have failed to capitalize on opportunities to improve quality, relevance, and outreach via digital interoperability, use of earth observation, and connectivity. Literature highlights scope for regulatory and institutional reforms to (a) expand property taxation and land value capture and to improve urban service delivery, planning, and land use regulations; (b) increase quality and affordability of land services and access to land price and ownership data; (c) guide issuance of rural land use rights to reduce barriers to rural factor markets, including by spatially enabling farmer registries to improve subsidy targeting and effectiveness; and (d) demarcation and transparent decentralized management of public land to attract investment, including in climate finance, without fueling corruption, and to manage disputes before they escalate into ethnic violence.Publication EdTech in Developing Countries: A Review of the Evidence(Published by Oxford University Press on behalf of the World Bank, 2021-08-02) Rodriguez-Segura, DanielThe emergence of educational technology (“EdTech”) in developing countries has been received as a promising avenue to address some of the most challenging policy questions within educational systems. In this paper, I review and synthesize all existing studies with credible causal identification frameworks of EdTech interventions in developing countries. While other studies review the evidence for EdTech interventions in developed countries, there is currently no equivalent study for developing contexts, in spite of the rising number of studies being produced. I classify studies into four thematic categories based on the type of EdTech intervention analyzed: Access to technology; technology-enabled behavioral interventions; improvements to instruction; and self-led learning. I find that EdTech interventions centered around self-led learning and improvements to instruction are the most effective forms of EdTech at raising learning outcomes. Similarly, technology-enabled behavioral interventions are less promising for generating large effects but highly cost-effective given their typically low marginal costs. Although expanding access to technology alone is not sufficient to improve learning, it is a necessary first step for some other types of interventions. More broadly, the overall success of interventions rests on the thoughtful customization of the EdTech solution to the policy constraints at hand. Finally, EdTech interventions across all thematic areas can and should act as complements by leveraging their respective comparative advantages to address deficiencies within educational systems in developing countries.Publication The Power and Roots of Aspirations(Published by Oxford University Press on behalf of the World Bank, 2025-01-24) Fruttero, Anna; Muller, Noel; Calvo-González, ÓscarAspirations have become a common theme in empirical economics studies but there is no unified understanding of the range of outcomes they influence, the factors that shape them, and how to measure them. We survey this growing literature. We argue that there is compelling evidence to consider aspirations as a useful lens to analyze human behavior and development outcomes, at the individual and aggregate levels, in poorer and richer countries. The empirical evidence aligns with the theory that high aspirations can lead individuals to achieve better educational, labor market, and other outcomes and can contribute to making countries more equal and prosperous. The empirical evidence also confirms that the mix of social and circumstantial factors shaping aspirations tends to hinder the aspirations of the disadvantaged—such as the poor, immigrants, and women—and can contribute to vicious circles of poverty, high inequality, low social mobility, and low growth. However, high aspirations should not be considered an end in themselves as they can backfire, with deleterious effects, if unmatched with opportunities. Further, we argue that definitional and measurement issues can affect the understanding of the topic and that studies should more explicitly describe their measures of aspirations to ensure that divergent underlying concepts are not mistaken.Publication Impacts of Extreme Weather Events on Education Outcomes: A Review of Evidence(Published by Oxford University Press on behalf of the World Bank, 2024-04-08) Venegas Marin, Sergio; Schwarz, Lara; Sabarwal, ShwetlenaExtreme weather events are increasingly disrupting schooling. Yet, these are underrepresented in the climate change literature. Of 15 review articles on the economic impacts of climate change published since 2010, only three mention the impacts of climate change on education. We review available literature on the effects of weather extremes on education. We outline key pathways through which these events impact education outcomes, as well as the magnitude of those impacts. Evidence implies a significant and adverse relationship between heat and learning. Studies suggest surpassing a high temperature threshold makes learning difficult and results in learning losses. Across studies, each additional day subject to extreme heat reduces learning. Tropical cyclones, floods, and wildfires precipitate school closures, which halt learning. Evidence suggests that one day of school closures leads to one day of learning lost. Weather extremes also negatively impact education outcomes through health, nutrition, poverty, and fragility, among other distal pathways. We discuss the implications of this evidence for policy, including the need to adapt education systems to climate change. Mitigation and adaptation are both urgently needed as extreme weather events become more frequent and severe in the context of climate change.Publication The Impact of Climate Change on Work: Lessons for Developing Countries(Published by Oxford University Press on behalf of the World Bank, 2025-01-24) Feriga, Moustafa; Lozano Gracia, Nancy; Serneels, PieterWe identify five areas where climate change may impact work and draw lessons for developing countries by reviewing the evidence. Firstly, demand for labor is unevenly affected, with agriculture, heat-exposed manufacturing, and the brown energy sector experiencing downturns, while other sectors may see a rise, resulting in an uncertain overall impact. Secondly, climate change impacts labor supply through absenteeism, shirking, and altering work-time patterns, depending on the activity and sector. Thirdly, productivity may decline, especially in heat-exposed industries, primarily due to health reasons. Fourthly, heightened earnings variability likely increases vulnerability among the self-employed. Fifthly, climate change can influence labor allocation and catalyze sectoral reallocation. Higher temperatures are also linked to increased migration. But caution is needed in interpreting these findings, as studies across these topics predominantly use fixed effect estimation and concentrate on short-term impacts, neglecting adaptation. Emerging research on adaptation indicates that workplace cooling is unappealing for firms with narrow profit margins, while coping strategies of farms and households have unclear optimality due to adoption barriers. Government responses remain understudied, with six potential areas identified: green jobs, green skills, labor-oriented adaptation, flexible work regulation, labor market integration, and social protection. We conclude by outlining future research directions.Publication Measuring Total Carbon Pricing(Published by Oxford University Press on behalf of the World Bank, 2023-09-27) Agnolucci, Paolo; Fischer, Carolyn; Heine, Dirk; Montes de Oca Leon, Mariza; Pryor, Joseph; Patroni, Kathleen; Hallegatte, StéphaneWhile countries increasingly commit to pricing greenhouse gases directly through carbon taxes or emissions trading systems, indirect forms of carbon pricing - such as fuel excise taxes and fuel subsidy reforms - remain important factors affecting the mitigation incentives in an economy. Taken together, how can policy makers think about the overall price signal for carbon emissions and the incentive it creates We develop a methodology for calculating a total carbon price applied to carbon emissions in a sector, a fuel, or the whole economy. We recognize that rarely is a single carbon price applied across an economy; many direct carbon pricing instruments target specific sectors or even fuels, much like indirect taxes on fossil fuels; and carbon and fuel taxes can be substituted for one another. Tracking progress on carbon pricing thus requires following both kinds of price interventions, their coverage, and specific exemptions. This inclusive total carbon pricing measure can facilitate progress in discussions on minimum carbon price commitments and inform assessments of the pricing of carbon embodied in traded goods. Calculations across 142 countries from 1991 to 2021 indicate that although direct carbon pricing now covers roughly one-quarter of global emissions, the global total carbon price is not that much higher than it was in 1994 when the United Nations Framework Convention on Climate Change entered into force. Indirect carbon pricing still comprises the lion's share of the global total carbon price, and it has stagnated. Taking these policy measures into account reveals that many developing countries - particularly net fuel importers - contribute substantially to global carbon pricing. Tackling fuel subsidy reform and pricing coal and natural gas emissions more fully would have a profound effect on aligning carbon prices across countries and sectors and with their climate costs.Publication The Relationship between Climate Action and Poverty Reduction(Published by Oxford University Press on behalf of the World Bank, 2023-12-30) Lankes, Hand Peter; Macquarie, Rob; Soubeyran, Éléonore; Stern, NicholasThere is growing awareness that actions by policymakers and international organizations to reduce poverty, and those to mitigate and adapt to climate change, are inextricably linked and interwoven. This paper examines relevant academic and policy literature and evidence on this relationship and explores the potential for a new form of development that simultaneously mitigates climate change, manages its impacts, and improves the wellbeing of people in poverty. First, as a key foundation, it outlines the backdrop in basic moral philosophy, noting that climate action and poverty reduction can be motivated both by a core principle based on the right to development and by the conventional consequentialism that is standard in economics. Second, it reviews assessments of the current and potential future impacts of weakly managed climate change on the wellbeing of those in poverty, paying attention to unequal effects, including by gender. Third, it examines arguments and literature on the economic impacts of climate action and policies and how those affect the wellbeing of people in poverty, highlighting the importance of market failures, technological change, systemic dynamics of transition, and distributional effects of mitigation and adaptation. Finally, the paper surveys the current state of knowledge and understanding of how climate action and poverty reduction can be integrated in policy design, indicating where further research can contribute to a transition that succeeds in both objectives.Publication The Promise and Limitations of Information Technology for Tax Mobilization(Published by Oxford University Press on behalf of the World Bank, 2022-10-20) Okunogbe, Oyebola; Santoro, FabrizioTax revenue in many low- and middle-income countries is inadequate for funding investments in public goods and human capital. With high levels of informality and limited state capacity, many tax authorities have difficulty determining the true tax base and collecting taxes efficiently and equitably. Tax authorities are increasingly adopting new technologies to improve administrative processes, reduce taxpayer compliance costs, and enhance their overall effectiveness. This paper reviews the recent literature on the use of technology for tax administration. It highlights the potential of technology to improve tax collection by helping to identify the tax base, monitor compliance, and facilitate compliance. It also identifies possible limitations to the use of technology arising from inadequate infrastructure and connectivity, lack of adoption or resistance by taxpayers and tax collectors, lack of institutional mainstreaming, and an unsupportive regulatory environment.Publication Impacts of Temporary Migration on Development in Origin Countries(Published by Oxford University Press on behalf of the World Bank, 2023-04-17) Bossavie, Laurent; Özden, ÇağlarTemporary migration is widespread globally. While the literature has traditionally focused on the impacts of permanent migration on destination countries, evidence on the effects of temporary migration on origin countries has grown over the past decade. This paper highlights that the economic development impacts, especially on low- and middle-income origin countries, are complex, dynamic, context-specific, and multichanneled. The paper identifies five main pathways: (a) labor supply; (b) human capital; (c) financial capital and entrepreneurship; (d) aggregate welfare and poverty; and (e) institutions and social norms. Several factors shape these pathways and their eventual impacts. These include initial economic conditions at home, the scale and double selectivity of emigration and return migration, whether migration was planned to be temporary ex ante, and employment and human capital accumulation opportunities experienced by migrants while they are overseas. Meaningful policy interventions to increase the development impacts of temporary migration require proper analysis, which, in turn, depends on high-quality data on workers’ employment trajectories, as well as their decision processes on the timing of their migration and return. These are currently the biggest research challenges to overcome to study the development impacts of temporary migration.Publication Social Norms and Gender Disparities with a Focus on Female Labor Force Participation in South Asia(Published by Oxford University Press on behalf of the World Bank, 2023-09-23) Bussolo, Maurizio; Ezebuihe, Jessy Amarachi; Muñoz Boudet, Ana Maria; Poupakis, Stavros; Rahman, Tasmia; Sarma, NayantaraDespite decades of economic growth, gender disparities in South Asia remain remarkably high. Although not the only one, social norms are a crucial driver of various gender outcomes, including differential economic participation. Using repeated cross-sectional data from nationally representative surveys, this study explores long-term trends across gender outcomes and social norms(contrasting attitudes and social normative expectations towards gender roles) in South Asia. The results corroborate the evidence that there has been almost no progress in gender disparities in South Asia over the past half-century. There has been little progress in female labor force participation, age at first birth, agency, and intimate partner violence, while (basic) education is an important exception. The lack of progress is apparent among all layers of society, including women who live in urban areas, are educated, and have higher incomes. Gender attitudes also remain unchanged, while for some issues, they have become more conservative and have a negative relationship with gender outcomes. This negative relationship is even stronger when social normative expectations are considered. More data on social norms and a better understanding of their constraining role may be critical for achieving gender equality in the region.
