Abstract
Many developing countries display remarkably high degrees of urban concentration that are incommensurate with their levels of urbanization. The cost of excessively high levels of urban concentration can be very high in terms of overpopulation, congestion, and productivity growth. One strand of the theoretical literature suggests that such high levels of concentration may be the result of restrictive trade policies that trigger forces of agglomeration. Another strand of the literature, however, points out that trade liberalization itself may exacerbate urban concentration by favoring the further growth of those large urban centers that have better access to international markets. The empirical basis for judging this question has been weak so far; in the existing literature, trade policies are poorly measured (or are not measured, as when trade volumes are used spuriously). Here, we use new disaggregated tariff measures to empirically test the hypothesis. We also employ a treatment-and-control analysis of pre- versus post-liberalization performance of the cities in liberalizing and non-liberalizing countries. We find evidence that (controlling for the largest cities that have ports and, thus, have better access to external markets) liberalizing trade leads to a reduction in urban concentration.

Publication Regional Poverty and Inequality Update: Latin America and the Caribbean, October 2025(Washington, DC: World Bank, 2025-10-23)This brief summarizes recent facts related to poverty and inequality in Latin America and the Caribbean (LAC) using the latest wave of harmonized household surveys from the Socio-Economic Database for LAC (SEDLAC). This brief was produced by the Poverty Global Practice in the LAC Region of the World Bank.Publication World Development Report 2018(Washington, DC: World Bank, 2018)Every year, the World Bank's World Development Report takes on a topic of central importance to global development. The 2018 Report, Learning to Realize Education's Promise, is the first ever devoted entirely to education. Now is an excellent time for it: education has long been critical for human welfare, but is even more so in a time of rapid economic change. The Report explores four main themes. First, education's promise: Education is a powerful instrument for eradicating poverty and promoting shared prosperity, but fulfilling its potential requires better policies - both within and outside the education system. Second, the learning crisis: Despite gains in education access, recent learning assessments show that many young people around the world, especially from poor families, are leaving school unequipped with even the most foundational skills they need for life. At the same time, internationally comparable learning assessments show that skills in many middle-income countries lag far behind what those countries aspire to. Third, promising interventions to improve learning: Research from areas such as brain science, pedagogical innovations, or school management have identified interventions that promote learning by ensuring that learners are prepared, that teachers are skilled as well as motivated, and that other inputs support the teacher-learner relationship. Fourth, learning at scale: Achieving learning throughout an education system will require more than just scaling up effective interventions. Change requires overcoming technical and political barriers by deploying salient metrics for mobilizing actors and tracking progress, building coalitions for learning, and being adaptive when implementing programs.Publication Digital Africa(Washington, DC: World Bank, 2023-03-13)All African countries need better and more jobs for their growing populations. "Digital Africa: Technological Transformation for Jobs" shows that broader use of productivity-enhancing, digital technologies by enterprises and households is imperative to generate such jobs, including for lower-skilled people. At the same time, it can support not only countries’ short-term objective of postpandemic economic recovery but also their vision of economic transformation with more inclusive growth. These outcomes are not automatic, however. Mobile internet availability has increased throughout the continent in recent years, but Africa’s uptake gap is the highest in the world. Areas with at least 3G mobile internet service now cover 84 percent of Africa’s population, but only 22 percent uses such services. And the average African business lags in the use of smartphones and computers as well as more sophisticated digital technologies that catalyze further productivity gains. Two issues explain the usage gap: affordability of these new technologies and willingness to use them. For the 40 percent of Africans below the extreme poverty line, mobile data plans alone would cost one-third of their incomes—in addition to the price of access devices, apps, and electricity. Data plans for small- and medium-size businesses are also more expensive than in other regions. Moreover, shortcomings in the quality of internet services—and in the supply of attractive, skills-appropriate apps that promote entrepreneurship and raise earnings—dampen people’s willingness to use them. For those countries already using these technologies, the development payoffs are significant. New empirical studies for this report add to the rapidly growing evidence that mobile internet availability directly raises enterprise productivity, increases jobs, and reduces poverty throughout Africa. To realize these and other benefits more widely, Africa’s countries must implement complementary and mutually reinforcing policies to strengthen both consumers’ ability to pay and willingness to use digital technologies. These interventions must prioritize productive use to generate large numbers of inclusive jobs in a region poised to benefit from a massive, youthful workforce—one projected to become the world’s largest by the end of this century.Publication State of the Art of Social Registries in Latin America and the Caribbean(Washington, DC: World Bank, 2025-01-21)The World Bank has worked to strengthen social registries in LAC and globally for several decades. This technical note aims to contribute to reducing the knowledge gap on the state of the art and challenges of social registries in LAC, identify where they are about various analysis criteria, and generate recommendations on strategies to strengthen and consolidate their role in the design, implementation, and evaluation of social policies in the region. This technical note is organized into five sections, including this introduction. The second section presents the role of social registries in social policy. Section three presents the evolution of social registries in LAC and how they adapted to the challenges that arose to provide immediate responses during the COVID-19 pandemic. The fourth part generally describes the state of the art of social registries in the region, analyzed from five pillars: (i) institutional arrangements, (ii) structural aspects, (iii) implementation chain, (iv) information and interoperability systems, and (v) performance measures. The fifth section presents the main challenges facing the registries and the study's recommendations.Publication Reality Check(Washington, DC: World Bank, 2023-09-19)To address the myriad challenges posed by global climate change, countries at all income levels have put in place a diverse set of policies over the past three decades. Many governments have already made significant progress in their efforts to decarbonize, creating a rich history of implementation experiences that provides important lessons for how to successfully advance climate policy goals in a variety of different economic, cultural, and political contexts. Despite this progress, the transition to a net zero future continues to face significant barriers, including the need for large investment, a lack of institutional capacity, and challenging political economy issues. ‘Reality Check: Lessons from 25 Policies Advancing a Low-Carbon Future’ identifies key policy approaches that countries are taking to decarbonize their economies. The report classifies policies into five categories: 1. Planning for a future with zero net emissions; 2. Getting the pricing and taxes right; 3. Facilitating and triggering transitions in key systems, such as energy and food; 4. Getting the finance flowing, particularly by incentivizing private sector investment; 5. Ensuring a just transition that protects the poor. ‘Reality Check: Lessons from 25 Policies Advancing a Low-Carbon Future’ fills a critical research gap by documenting low-carbon policy trends and providing a series of case studies across sectors and geographies. The 25 case studies furnish country contexts and policy details, examine results and impacts, and outline key takeaways and lessons learned for enabling further ambition in achieving emissions reductions. The report contributes to an evolving analytical agenda on how to reduce carbon emissions while achieving economic development and the strategic transition to a greener, more resilient, and more inclusive future.
