Abstract
This study discusses potential economic implications for Nigeria of an Economic Partnership Agreement with the European Union. It uses the World Bank s Tariff Reform Impact Simulation Tool to assess the effects of preferential tariff liberalization with respect to the European Union. The results suggest that the impact of an Economic Partnership Agreement on total imports into Nigeria will be slight. This is in part because the Agreement will likely allow the most protected sectors to be excluded from liberalization, and also because where substantial tariffs are involved much of the increase in imports from the European Union will occur at the expense of other suppliers of imports. It is this trade diversion, arising from the discriminatory nature of the EPA, which generates a negative welfare impact of the tariff reforms. One way for Nigeria to limit these losses is to pursue non-preferential trade liberalization before implementing an EPA. The paper looks at the large number of import bans in Nigeria and argues that the positive impact on welfare of removing these import bans is likely to be substantial. Their removal would undermine a major reason for cross border smuggling and pave the way for a return to normal regional trade flows. The paper shows how an Economic Partnership Agreement presents an opportunity for accelerating the reforms that are needed to support a strategy to increase regional and global trade integration. Such an agreement is more likely to have positive and significant impacts when integrated into a comprehensive strategy toward competitiveness and alleviation of the supply constraints that have stifled the impact of previous trade agreements. Key issues that should be addressed include liberalization and regulatory strengthening of services sectors to ensure that all firms in Nigeria have access to efficiently produced backbone services and initiatives to address the country s poor trade logistics performance.

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 Impact of Trade Promotion Organizations on Exports(Washington, DC: World Bank, 2025-08-13)This paper examines the impact of trade promotion organizations on exports during the COVID-19 pandemic using a World Bank survey. The results suggest that increased trade promotion organization budgets significantly boosted exports during downturns but had no effect during the recovery phase. Interestingly, e-commerce programs adopted by trade promotion organizations negatively affected exports during downturns as they diverted resources away from productive support, especially for sectors not intensive in online trade. These findings suggest that countercyclical trade promotion organizations budgets may enhance trade resilience during similar global shocks.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 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 Climate Vulnerability and Job Accessibility(Washington, DC: World Bank, 2025-08-11)Many developing cities are facing rapid population growth and extreme climate events. This paper examines the link between job accessibility and climate vulnerability, using data from Antananarivo, Madagascar, which frequently experiences flooding. As in other countries, the analysis finds that men’s commutes are longer than women’s, who tend to walk to work or use public transport. Even after controlling for observables and the potential endogeneity bias associated with commute time, the findings show that climate vulnerability negatively impacts wages, as people avoid commuting long to work due to anticipated potential climate risks. Building climate resilience into urban transport is therefore essential. As predicted by theory, the evidence also shows that the value of commuting is positive, and walking is disadvantageous. Motorized commuting yields higher returns, which could lead to overuse of private cars and taxis, posing decarbonization challenges.

Publication Economic Partnership Agreements and the Export Competitiveness of Africa(World Bank, Washington, DC, 2008-05)Trade can be a key driver of growth for African countries, as it has been for those countries, particularly in East Asia, that have experienced high and sustained rates of growth. Economic partnership agreements with the European Union could be instrumental in a competitiveness framework, but to do so they would have to be designed carefully in a way that supports integration into the global economy and is consistent with national development strategies. Interim agreements have focused on reciprocal tariff removal and less restrictive rules of origin. To be fully effective, economic partnership agreements will have to address constraints to regional integration, including both tariff and non-tariff barriers; improve trade facilitation; and define appropriate most favored nation services liberalization. At the same time, African countries will need to reduce external tariff peak barriers on a most favored nation basis to ensure that when preferences for the European Union are implemented after transitional periods, they do not lead to substantial losses from trade diversion. This entails an ambitious agenda of policy reform that must be backed up by development assistance in the form of "aid for trade."Publication Strengthening Bolivian Competitiveness : Export Diversification and Inclusive Growth(World Bank, 2009-06-01)Bolivia's trade liberalization, launched in the mid-1980s, has resulted in a relatively open trade regime; but the results have been mixed. Bolivia's export to Gross Domestic Product (GDP) ratio and export entrepreneurship index rating are among the highest in the Latin American and Caribbean (LAC) region and the country has achieved great success in making soya the major export crop in less than 10 years. At the same time, the country's share in world trade has stagnated and exports are increasingly dominated by gas and minerals. Reinvigorating the nontraditional export sector is important for the government of Bolivia as it implements its national development plan. As a resource-rich country, the Bolivian government's emphasis on export diversification is well-placed but the optimal nontraditional export strategy should build on successes in the traditional sector. This study investigates: (a) the role trade should play in Bolivia's development strategy considering the country's natural resource endowment; (b) the lessons of Bolivia's integration to the world economy; (c) the linkages between Bolivia's past trade and economy and a forward-looking analysis of the impact of different scenarios on growth, employment, trade flows, and poverty; (d) constraints to higher export competitiveness and weaknesses related to transport and logistics; and (e) the characteristics of exporting firms and the constraints affecting them. The main findings of the analysis are that preferential access to world markets is necessary but not sufficient for success in nontraditional exports; rather, success depends largely on increasing the competitiveness of exporting firms. Second, a neutral incentive regime is essential to the growth of nontraditional exports. Third, efficient backbone services are vital for reducing exporters' costs. Finally, the government should be proactive in addressing institutional impediments to cross-border trade. The study presents prioritized policy implications of the analysis related to: (i) trade policy and preferential access to markets; (ii) the incentives regime; (iii) backbone services; (iv) increasing the effectiveness of institutions to promote cross-border trade; and (v) setting the foundations for exports diversification.Publication Regional Trade Agreements(2010-05-01)This paper reviews the theoretical and empirical literature on regionalism. The formation of regional trade agreements has been, by far, the most popular form of reciprocal trade liberalization in the past 15 years. The discriminatory character of these agreements has raised three main concerns: that trade diversion would be rampant, because special interest groups would induce governments to form the most distortionary agreements; that broader external trade liberalization would stall or reverse; and that multilateralism could be undermined. Theoretically, all of these concerns are legitimate, although there are also several theoretical arguments that oppose them. Empirically, neither widespread trade diversion nor stalled external liberalization has materialized, while the undermining of multilateralism has not been properly tested. There are also several aspects of regionalism that have received too little attention from researchers, but which are central to understanding its causes and consequences.Publication A Preliminary Analysis of the Impact of a Ukraine-EU Free Trade Agreement on Agriculture(2010-04-01)Agriculture including food products is of particular interest for Ukraine. However, in free trade agreements involving the European Union, agriculture is always given special treatment and subject to less and slower liberalization than other sectors. This paper employs the standard Global Trade Analysis Project model in order to assess how World Trade Organization accession affects agriculture in Ukraine, and how potential bilateral tariff cuts may interact with potential productivity gains within Ukrainian agriculture. The results indicate that, due to trade liberalization, Ukraine can expect gains from a more efficient allocation of its resources in line with comparative advantage, leading to an increase of production and exports of wheat, other grains, and oilseeds, but also of several processed food products that benefit from less expensive intermediate inputs. However, Ukraine's exports are concentrated on a small number of destinations, especially Russia and some other Former Soviet Union countries because they fail to meet quality standards elsewhere. When Ukrainian production of these products increases due to increased allocative efficiency, exports to Russia increase further and prices there fall, generating negative terms of trade effects that largely offset the allocative gains. Ukrainian imports of agricultural products increase as well, partly because Ukrainian consumers switch to higher quality imported goods even though domestic production increases. Regarding free trade agreement negotiations with the European Union, these results highlight for Ukraine the fact that improved agricultural productivity will help to get most out of improved market access. However, the results also highlight for Ukraine the great importance of adopting internationally accepted quality standards in order to diversify its export structure.Publication Challenges of CAFTA : Maximizing the Benefits for Central America(Washington, DC : World Bank, 2006)The report provides a preliminary assessment of DR-CAFTA (the Dominican Republic and Central American Free trade Agreement), with particular attention to three key themes: (1) expected trade and non-trade benefits, (2) actions that Central American countries need to pursue to capitalize optimally on the new opportunities, and (3) identification of the population groups that may require assistance to adapt to a more competitive environment. The Introductory Chapter reviews the main findings of the report. Chapter 2 places DR-CAFTA in the historical context of the economic reforms that Central America has been undertaking since the late 1980s. Chapter 3 provides a summary overview of the recently negotiated DR-CAFTA. Chapter 4 reviews various analyses that assess the potential impacts of DR-CAFTA in Central American countries. Chapter 5 focuses on the identification of potentially affected populations from the easing of trade restrictions in sensitive agricultural products and analyzes policy options to assist vulnerable groups. Chapter 6 reviews evidence related to key macroeconomic implications of DR-CAFTA, namely the potential revenue losses and effect on the patterns of business-cycle synchronization. Chapter 7 reviews evidence from each Central American country in the areas of trade facilitation, institutional and regulatory reforms, and innovation and education, in order to identify key priorities for the complementary agenda for DR-CAFTA.

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.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 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 The Journey Ahead(Washington, DC: World Bank, 2024-10-31)The Journey Ahead: Supporting Successful Migration in Europe and Central Asia provides an in-depth analysis of international migration in Europe and Central Asia (ECA) and the implications for policy making. By identifying challenges and opportunities associated with migration in the region, it aims to inform a more nuanced, evidencebased debate on the costs and benefits of cross-border mobility. Using data-driven insights and new analysis, the report shows that migration has been an engine of prosperity and has helped address some of ECA’s demographic and socioeconomic disparities. Yet, migration’s full economic potential remains untapped. The report identifies multiple barriers keeping migration from achieving its full potential. Crucially, it argues that policies in both origin and destination countries can help maximize the development impacts of migration and effectively manage the economic, social, and political costs. Drawing from a wide range of literature, country experiences, and novel analysis, The Journey Ahead presents actionable policy options to enhance the benefits of migration for destination and origin countries and migrants themselves. Some measures can be taken unilaterally by countries, whereas others require close bilateral or regional coordination. The recommendations are tailored to different types of migration— forced displacement as well as high-skilled and low-skilled economic migration—and from the perspectives of both sending and receiving countries. This report serves as a comprehensive resource for governments, development partners, and other stakeholders throughout Europe and Central Asia, where the richness and diversity of migration experiences provide valuable insights for policy makers in other regions of the world.
