Abstract
The actual distribution of world income across countries is extremely unequal, much higher than the within country inequality faced by most countries. The question studied in this paper is: How do international policies on aid, trade, and factor movements affect the international distribution of income? To begin to answer this question, the authors calculate the impact by decile of the actual level of aid flows and the effect on potential income of merchandise trade restrictions by high-income countries. They find that aid's distributional impact is equality enhancing. While it is extremely small in terms of changes in standard inequality measures, it is of some importance for the lowest decile of the world's income distribution. The authors also find that some of this impact is counteracted by lost potential income in the lower deciles from merchandise trade barriers imposed by high-income countries. In brief, there is a contradiction in international policies where aid's equality-enhancing effect is somewhat offset by protectionism. They also discuss some of the analytical difficulties with extending this analysis of redistribution to other forms of international factor flows-more specifically, migrant worker and profit remittances. The analysis presented is partial and static and ignores within country distribution. As such, the authors suggest that future research should explore the distributional consequences of the broader general equilibrium effects, dynamic effects, and externalities associated with aid, trade, and factor flows. Future research should also analyze the within country distributional impacts of international policies.

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 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 Gender Gaps in the Performance of Small Firms: Evidence from Urban Peru(Washington, DC: World Bank, 2025-09-23)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.Publication The Exposure of Workers to Artificial Intelligence in Low- and Middle-Income Countries(Washington, DC: World Bank, 2025-02-05)Research on the labor market implications of artificial intelligence has focused principally on high-income countries. This paper analyzes this issue using microdata from a large set of low- and middle-income countries, applying a measure of potential artificial intelligence occupational exposure to a harmonized set of labor force surveys for 25 countries, covering a population of 3.5 billion people. The approach advances work by using harmonized microdata at the level of individual workers, which allows for a multivariate analysis of factors associated with exposure. Additionally, unlike earlier papers, the paper uses highly detailed (4 digit) occupation codes, which provide a more reliable mapping of artificial intelligence exposure to occupation. Results within countries, show that artificial intelligence exposure is higher for women, urban workers, and those with higher education. Exposure decreases by country income level, with high exposure for just 12 percent of workers in low-income countries and 15 percent of workers in lower-middle-income countries. Furthermore, lack of access to electricity limits effective exposure in low-income countries. These results suggest that for developing countries, and in particular low-income countries, the labor market impacts of artificial intelligence will be more limited than in high-income countries. While greater exposure to artificial intelligence indicates larger potential for future changes in certain occupations, it does not equate to job loss, as it could result in augmentation of worker productivity, automation of some tasks, or both.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 World Bank Research Digest, Vol. 1(4)(Washington, DC, 2007-08)In this issue: the urbanization of global poverty; focus: macroeconomic volatility and development; brain waste? Educated immigrants in the U.S. labor market; inefficient lobbying, populism, and oligarchy; weaponomics: the global market for assault rifles; exit and exclusion as routes to informality; and will markets direct investments under the Kyoto Protocol?Publication Gaining from Migration : Trends and Policy Lessons in the Greater Mekong Sub-region(World Bank, Thailand, 2012)This report contributes to the migration policy debates in the Greater Mekong Sub-region (GMS) by providing evidence of the impacts of migration; at the same time, it outlines possible policy approaches to increase benefits from migration. The study focuses primarily on Thailand and Myanmar: the main labor receiving and sending countries, respectively, in the GMS. This report not only presents the recent migration trends and drivers in the GMS but also addresses policy issues related to the economic and social impact of migration on countries both receiving and sending labor; it also addresses the issue of migrants' welfare including social services; and the role of migration policy and institutions. The findings challenge several existing paradigms of developing country migration research and may have broader transferability. Specifically, the proceeding analysis suggests: (a) demographic and income differences among the GMS countries drive migration within the region, suggesting the rising prominence of South-South migration; (b) migration in the GMS tends to be long-term, contrasting the more temporary nature of migration from most of the world's developing countries; and (c) economic factors contribute to migration within the region significantly more so than political factors.Publication The Canada-Caribbean Remittance Corridor : Fostering Formal Remittances to Haiti and Jamaica through Effective Regulation(World Bank, 2009-04-01)The World Bank has been at the global forefront in research on remittances. Studying over twelve bilateral remittance corridors thus far, the financial market integrity unit has focused its research on remittance market integrity issues and the specific incentives influencing the choices of channels to send money home. Initially conducted at the request of Department of Finance, Canada, this corridor, Canada-Caribbean, has clearly distinguished itself from other bilateral remittance corridors studied in the past. At the originating end of this corridor, these distinguishing features include a country that, throughout its history, has made immigration one of its primary social and economic building blocks. This corridor focuses on Jamaica and Haiti, two of the Caribbean's primary labor exporters and also the countries with the two largest Caribbean communities in Canada. Given the importance of remittances in the region, there is a need for effective, yet proportionate regulation. Risk must be effectively mitigated along potentially vulnerable routes, while innovation, competition and transparency in the remittance markets must be encouraged. Regulatory frameworks that reflect local conditions and are proportionate to the risks involved will facilitate the provision of services of the highest quality to migrants and their families. It is hoped that research provided from this study will generate policy dialogues among all relevant stakeholders, and assist national authorities in their efforts to effectively regulate and supervise the remittance markets. National authorities should continue to encourage the use of formal transfers and develop more reliable and competitive remittance channels. These channels must efficiently meet the varied needs of Caribbean migrant workers and their families in the safest and most secure environment possible.Publication Experimental Approaches in Migration Studies(2010-08-01)The decision of whether or not to migrate has far-reaching consequences for the lives of individuals and their families. But the very nature of this choice makes identifying the impacts of migration difficult, since it is hard to measure a credible counterfactual of what the person and their household would have been doing had migration not occurred. Migration experiments provide a clear and credible way for identifying this counterfactual, and thereby allowing causal estimation of the impacts of migration. The authors provide an overview and critical review of the three strands of this approach: policy experiments, natural experiments, and researcher-led field experiments. The purpose is to introduce readers to the need for this approach, give examples of where it has been applied in practice, and draw out lessons for future work in this area.Publication Global Migration Revisited(World Bank, Washington, DC, 2016-04)This paper re-examines the development implications of international migration focusing on two issues: how the costs and benefits of migration change over time, and the significance of South-South migration for development. First, the analysis finds that although greater migration could push down the wages of native workers of advanced countries in the short run, these wages eventually recover. This pattern would be mostly caused by the beneficial effect of additional labor on the real returns on capital and fostering faster capital formation. Additional South-North migration could favor capital income recipients and reduces labor income in host regions in the short run. In contrast, in sending countries, capital owners could experience lower incomes while wages rise. Globally, the welfare gains of new migrants could be expected to exceed the losses of old migrants by a wide margin. The remaining natives in sending countries could enjoy a net increase in remittances as well as an increase in labor income, although income from capital might decline. Second, in a hypothetical scenario with lower South-South migration, the implied losses of remittance income could lead to substantially lower welfare in developing countries. Although the wage differentials among developing countries tend to be smaller relative to their wage differentials with high-income countries, South-South migrants make substantial contributions to remittances.

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 Lebanon Economic Monitor, Fall 2022(Washington, DC, 2022-11)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.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 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 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.
