Abstract
This paper reviews the existing literature on the impact of migrants networks on the patterns of international migration. It covers the theoretical channels at stake in the global effect of the networks. It identifies the key issues, namely the impact on size, selection and concentration of the migration flows. The paper also reviews the empirical hurdles that the researchers face in assessing the importance of networks. The key issues concern the choice of micro vs a macro approach, the definition of a network, the access to suitable data and the adoption of econometric methods accounting for the main features of those data. Finally, the paper reports a set of estimation outcomes reflecting the main findings of the macro approach.

Publication Intergenerational Income Mobility around the World(Washington, DC: World Bank, 2025-07-09)This paper introduces a new global database with estimates of intergenerational income mobility for 87 countries, covering 84 percent of the world’s population. This marks a notable expansion of the cross-country evidence base on income mobility, particularly among low- and middle-income countries. The estimates indicate that the negative association between income mobility and inequality (known as the Great Gatsby Curve) continues to hold across this wider range of countries. The database also reveals a positive association between income mobility and national income per capita, suggesting that countries achieve higher levels of intergenerational mobility as they grow richer.Publication The Future of Poverty(Washington, DC: World Bank, 2025-07-15)Climate change is increasingly acknowledged as a critical issue with far-reaching socioeconomic implications that extend well beyond environmental concerns. Among the most pressing challenges is its impact on global poverty. This paper projects the potential impacts of unmitigated climate change on global poverty rates between 2023 and 2050. Building on a study that provided a detailed analysis of how temperature changes affect economic productivity, this paper integrates those findings with binned data from 217 countries, sourced from the World Bank’s Poverty and Inequality Platform. By simulating poverty rates and the number of poor under two climate change scenarios, the paper uncovers some alarming trends. One of the primary findings is that the number of people living in extreme poverty worldwide could be nearly doubled due to climate change. In all scenarios, Sub-Saharan Africa is projected to bear the brunt, contributing the largest number of poor people, with estimates ranging between 40.5 million and 73.5 million by 2050. Another significant finding is the disproportionate impact of inequality on poverty. Even small increases in inequality can lead to substantial rises in poverty levels. For instance, if every country’s Gini coefficient increases by just 1 percent between 2022 and 2050, an additional 8.8 million people could be pushed below the international poverty line by 2050. In a more extreme scenario, where every country’s Gini coefficient increases by 10 percent between 2022 and 2050, the number of people falling into poverty could rise by an additional 148.8 million relative to the baseline scenario. These findings underscore the urgent need for comprehensive climate policies that not only mitigate environmental impacts but also address socioeconomic vulnerabilities.Publication Engineering Ukraine’s Wirtschaftswunder(Washington, DC: World Bank, 2025-07-29)As Ukraine emerges from the devastation of war, it faces a historic opportunity to engineer its own Wirtschaftswunder—a productivity-driven economic transformation akin to post-war West Germany. While investment-led growth may offer quick wins, it is efficiency, innovation, and institutional reform that will determine Ukraine’s long-term economic trajectory. Drawing on rich micro-level firm data spanning 25 years, this paper uncovers deep structural distortions that have suppressed creative destruction and productivity in Ukraine. It finds that business dynamism is on the decline, alongside rising market concentration among incumbent businesses, including low productivity state owned enterprises. To inform priorities for reviving business dynamism, this study develops a model of creative destruction drawing on Acemoglu et al. (2018) and Akcigit et al. (2021). The quantitative assessment highlights that policies that discipline entrenched incumbents are the bedrock for reviving business dynamism and engineer Ukraine’s Wirtschaftswunder. Policies targeting specific types of firms have limited efficacy when incumbents run wild.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 Disentangling the Key Economic Channels through Which Infrastructure Affects Jobs(Washington, DC: World Bank, 2025-04-03)This paper takes stock of the literature on infrastructure and jobs published since the early 2000s, using a conceptual framework to identify the key channels through which different types of infrastructure impact jobs. Where relevant, it highlights the different approaches and findings in the cases of energy, digital, and transport infrastructure. Overall, the literature review provides strong evidence of infrastructure’s positive impact on employment, particularly for women. In the case of electricity, this impact arises from freeing time that would otherwise be spent on household tasks. Similarly, digital infrastructure, particularly mobile phone coverage, has demonstrated positive labor market effects, often driven by private sector investments rather than large public expenditures, which are typically required for other large-scale infrastructure projects. The evidence on structural transformation is also positive, with some notable exceptions, such as studies that find no significant impact on structural transformation in rural India in the cases of electricity and roads. Even with better market connections, remote areas may continue to lack economic opportunities, due to the absence of agglomeration economies and complementary inputs such as human capital. Accordingly, reducing transport costs alone may not be sufficient to drive economic transformation in rural areas. The spatial dimension of transformation is particularly relevant for transport, both internationally—by enhancing trade integration—and within countries, where economic development tends to drive firms and jobs toward urban centers, benefitting from economies scale and network effects. Turning to organizational transformation, evidence on skill bias in developing countries is more mixed than in developed countries and may vary considerably by context. Further research, especially on the possible reasons explaining the differences between developed and developing economies, is needed.

Publication Migration and Remittances during the Global Financial Crisis and Beyond(Washington, DC: World Bank, 2012-06-01)Immigrants tend to be more negatively affected by economic crisis than natives, particularly when governments apply strict immigration controls. With the onset of the financial crisis in the latter half of 2008, there were widespread concerns: would migrants return to sending countries and communities in large numbers, adding further economic woes to countries already facing difficulties? Would remittance flows slow and potentially cease? The literature offers little guidance on these questions. It is always a challenge to collect data, analyze, interpret, and make recommendations as the phenomenon under study is still unfolding to reveal new turns and twists. The most recent financial crisis and its repercussions are yet to be completed, and scholars have only begun processing the event. This volume is an effort to bring together in one place fresh thinking and evidence from around the world on the outcomes of mobility in the context of global financial crisis. This book is perhaps the first comprehensive study of remittances during the financial crisis and is a timely addition to the literature. It comes at a time when countries are grappling with the global financial crisis and it's after effects. The resilience of remittances is good news for developing countries, but leveraging remittances for socioeconomic development remains a key challenge. The studies in this book identify and discuss key patterns observed in remittance practices across the world and possibilities for the future.Publication Diasporas(2009-07-01)Migration flows are shaped by a complex combination of self-selection and out-selection mechanisms. In this paper, the authors analyze how existing diasporas (the stock of people born in a country and living in another one) affect the size and human-capital structure of current migration flows. The analysis exploits a bilateral data set on international migration by educational attainment from 195 countries to 30 developed countries in 1990 and 2000. Based on simple micro-foundations and controlling for various determinants of migration, the analysis finds that diasporas increase migration flows, lower the average educational level and lead to higher concentration of low-skill migrants. Interestingly, diasporas explain the majority of the variability of migration flows and selection. This suggests that, without changing the generosity of family reunion programs, education-based selection rules are likely to have a moderate impact. The results are highly robust to the econometric techniques, accounting for the large proportion of zeros and endogeneity problems.Publication International Migration, Economic Development and Policy(Washington, DC: World Bank and Palgrave Macmillan, 2007)This volume reflects the expansion of the World Bank Research Program on International Migration and Development into new substantive and geographic areas. It presents a new global migration database and includes studies of the determinants and impact of return and circular migration, the impact of the flow of ideas on fertility, host country policies and their impact on immigrants, and the impact of international migration and remittances on poverty and other development indicators. The studies cover countries from Latin America, North Africa, South Asia, the South Pacific, and Western Europe, and show that the impact of migration on education and health tends to benefit girls more than boys, that its impact on labor force participation tends to be stronger for women than men, that return migrants tend to do better than non-migrants, and that fertility has tended to decline in countries whose migration has been to the West and has failed to do so in countries whose migration has been to the Gulf. The purpose of the case studies is to illustrate and clarify many theoretical mechanisms and to advance understanding of the impact of different migration policies, given that introducing policy variables in econometric regressions is generally difficult. Each study in this volume aims to answer a variety of development- and policy-related questions using the most appropriate of these three methodologies. These empirical studies and analyses include exploration of some novel hypotheses; they are also new in terms of the topics selected and the regions/ countries examinedPublication Eight Questions about Brain Drain(2011-05-01)High-skilled emigration is an emotive issue that in popular discourse is often referred to as brain drain, conjuring images of extremely negative impacts on developing countries. Recent discussions of brain gain, diaspora effects, and other advantages of migration have been used to argue against this, but much of the discussion has been absent of evidence. This paper builds upon a new wave of empirical research to answer eight key questions underlying much of the brain drain debate: 1) What is brain drain? 2) Why should economists care about it? 3) Is brain drain increasing? 4) Is there a positive relationship between skilled and unskilled migration? 5) What makes brain drain more likely? 6) Does brain gain exist? 7) Do high-skilled workers remit, invest, and share knowledge back home? and 8) What do we know about the fiscal and production externalities of brain drain?Publication Leveraging Migration for Africa : Remittances, Skills, and Investments(World Bank, 2011-04-26)International migration has profound implications for human welfare, and African governments have had only a limited influence on welfare outcomes, for good or ill. Improved efforts to manage migration will require information on the nature and impact of migratory patterns. This book seeks to contribute toward this goal, by reviewing previous research and providing new analyses (including surveys and case studies) as well as by formulating policy recommendations that can improve the migration experience for migrants, origin countries, and destination countries. The book comprises this introduction and summary and four chapters. Chapter one reviews the data on African migration and considers the challenges African governments face in managing migration. Chapter two discusses the importance of remittances, the most tangible link between migration and development; it also identifies policies that can facilitate remittance flows to Africa and increase their development impact. Chapter three analyzes high-skilled emigration and analyzes policies that can limit adverse implications and maximize positive implications for development. Chapter four considers ways in which Africa can leverage its diaspora resources to increase trade, investment, and access to technology.

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 MIGA Annual Report 2021(Washington, DC: Multilateral Investment Guarantee Agency, 2021-10-01)In FY21, MIGA issued 5.2 billion US Dollars in new guarantees across 40 projects. These projects are expected to provide 784,000 people with new or improved electricity service, create over 14,000 jobs, generate over 362 million US Dollars in taxes for the host countries, and enable about 1.3 billion US Dollars in loans to businesses—critical as countries around the world work to keep their economies afloat. Of the 40 projects supported during FY21, 85 percent addressed at least one of the strategic priority areas, namely, IDA-eligible countries (lower-income), fragile and conflict affected situations (FCS), and climate finance. As of June 2021, MIGA has also issued 5.6 billion US Dollars of guarantees through our COVID-19 Response Program and anticipate an expansion to 10–12 billion US Dollars over the coming years, a testament to the countercyclical role that MIGA can play in mobilizing private investment in the face of the pandemic. A member of the World Bank Group, MIGA is committed to strong development impact and promoting projects that are economically, environmentally, and socially sustainable. MIGA helps investors mitigate the risks of restrictions on currency conversion and transfer, breach of contract by governments, expropriation, and war and civil disturbance, as well as offering credit enhancement on sovereign obligations.Publication IFC Annual Report 2011 : I Am Opportunity(Washington, DC: World Bank, 2011)This annual report of the IFC reviews the years accomplishments. IFC, a member of the World Bank Group, is the largest global development institution focused exclusively on the private sector.

It replaces and improves upon the Doing Business project. B-READY provides a comprehensive data set and description of the factors that strengthen the private sector, not only by advancing the interests of individual firms but also by elevating the interests of workers, consumers, potential new enterprises, and the natural environment. This 2024 report introduces a new analytical framework that benchmarks economies based on three pillars: Regulatory Framework, Public Services, and Operational Efficiency. The analysis centers on 10 topics essential for private sector development that correspond to various stages of the life cycle of a firm. The report also offers insights into three cross-cutting themes that are relevant for modern economies: digital adoption, environmental sustainability, and gender. B-READY draws on a robust data collection process that includes specially tailored expert questionnaires and firm-level surveys. The 2024 report, which covers 50 economies, serves as the first in a series that will expand in geographical coverage and refine its methodology over time, supporting reform advocacy, policy guidance, and further analysis and research.
