Abstract
Latin America’s historically low saving rates and sub-par growth performance raise the question of whether the region should save more to grow faster. Economists generally resist acknowledging a policy-exploitable causal connection going from saving to growth because domestic saving is perceived to be fully endogenous, optimally determined, or fully substitutable by foreign saving. However, to the extent that these three assumptions do not hold, three channels can be established through which higher domestic saving—by curbing persistent current account deficits—can promote medium-term growth. The channels are first, a real interest rate channel, whereby higher saving reduces the cost of capital and enhances macro sustainability; second, a real exchange rate channel, through which higher saving leads to a more competitive real exchange rate; and third, an endogenous saving channel, whereby saving follows growth and, hence, subsequently compounds the effect of the first two channels. Econometric evidence supports all three channels and suggests that the lower-saving countries in Latin America and the Caribbean, especially those with recurrently weak balance of payments and persistent domestic demand pressures on the non-tradable sector, would benefit the most from boosting their saving rates.

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 Economic Value of Weather Forecasts: A Quantitative Systematic Literature Review(Washington, DC: World Bank, 2025-09-10)This study systematically reviews the literature that quantifies the economic benefits of weather observations and forecasts in four weather-dependent economic sectors: agriculture, energy, transport, and disaster-risk management. The review covers 175 peer-reviewed journal articles and 15 policy reports. Findings show that the literature is concentrated in high-income countries and most studies use theoretical models, followed by observational and then experimental research designs. Forecast horizons studied, meteorological variables and services, and monetization techniques vary markedly by sector. Estimated benefits even within specific subsectors span several orders of magnitude and broad uncertainty ranges. An econometric meta-analysis suggests that theoretical studies and studies in richer countries tend to report significantly larger values. Barriers that hinder value realization are identified on both the provider and user sides, with inadequate relevance, weak dissemination, and limited ability to act recurring across sectors. Policy reports rely heavily on back-of-the-envelope or recursive benefit-transfer estimates, rather than on the methods and results of the peer-reviewed literature, revealing a science-to-policy gap. These findings suggest substantial socioeconomic potential of hydrometeorological services around the world, but also knowledge gaps that require more valuation studies focusing on low- and middle-income countries, addressing provider- and user-side barriers and employing rigorous empirical valuation methods to complement and validate theoretical models.Publication The Marshall Plan: Then and Now(Washington, DC: World Bank, 2025-10-14)This paper is a product of the Development Policy Team, Development Economics. It is part of a larger effort by the World Bank to provide open access to its research and make a contribution to development policy discussions around the world.

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 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 Can Latin America Tap the Globalization Upside?(World Bank, Washington, DC, 2014-04)This paper discusses the theoretical arguments in favor of and against economic globalization and, with a view to ascertaining whether Latin America may be able to capture the globalization upside, examines the trends and salient features of Latin America's globalization as compared with that of Southeast Asia. The paper focuses on trade and financial integration as well as the aggregate demand structures (domestic demand-driven versus external demand-driven) that underpin the globalization process. It finds that Latin America is mitigating some bad side effects of financial globalization by moving toward a safer form of international financial integration and improving its macro-financial policy frameworks. Nonetheless, Latin America's progress in raising the quality of its international trade integration has been scant. The region's commodity-heavy trade structures and relatively poor quality of trade connectivity can hinder growth potential to the extent that they are less conducive to technology and learning spillovers. Moreover, Latin America's domestic demand-driven growth pattern (a reflection of relatively low domestic savings) may become an additional drag to growth by accentuating the risk of a low savings-low external competitiveness trap.Publication Banking Flows and Financial Crisis : Financial Interconnectedness and Basel III Effects(2011-08-01)This paper examines the factors that determine banking flows from advanced economies to emerging markets. In addition to the usual determinants of capital flows in terms of global push and local pull factors, it examines the role of bilateral factors, such as growth differentials and economic size, as well as contagion factors and measures of the depth in financial interconnectedness between lenders and borrowers. The analysis finds profound differences across regions. In particular, in spite of the severe impact of the global financial crisis, banking flows in emerging Europe stand out as a more stable region than is the case in other developing regions. Assuming that the determinants of banking flows remain unchanged in the presence of structural changes, the authors use these results to explore the short-term implications of Basel III capital regulations on banking flows to emerging markets.Publication World Bank East Asia and Pacific Economic Update 2010, Volume 2 : Robust Recovery, Rising Risks(World Bank, 2010)Output has recovered to above pre-crisis levels throughout developing East Asia and, in some countries, is expanding at near pre-crisis rates. Real Gross Domestic Product (GDP) is likely to rise 8.9 percent in the region in 2010, up from 7.3 percent in 2009 and in line with the average growth rate during 2000-08. Economic expansion is projected to slow to about 7.8 percent in 2011, as spare capacity becomes scarce, fiscal and monetary stimulus measures are gradually unwound, and economic growth in the advanced economies remains relatively flat. Encouragingly, the private sector is once again becoming the engine of growth, confidence is returning, and trade flows have returned to pre-crisis levels. But the recovery so far has generated little incremental manufacturing employment in some of the middle-income countries. With output gaps closing rapidly and private investment recovering strongly, the authorities in most East Asian countries are unwinding their stimulus measures. Finally, a more consistent application of policy incentives for investment and growth across space is called for, especially recognizing China's unique combination of fiscal decentralization and centralized government structure. Extending preferential policies related to taxation and deregulation further inland, broadening the access to credit, and standardizing basic health and education services across provinces will greatly level the playing field in favor of the inland provinces, improving both equity and growth.Publication Financial Globalization in Emerging Economies : Much Ado about Nothing?(2011-04-01)Financial globalization, defined as global linkages through cross-border financial flows, has become increasingly relevant for emerging markets as they integrate financially with the rest of the world. This paper argues that, because of the way it is often measured, it has also led to the misperception that financial globalization in emerging markets has been growing in recent years. The authors characterize the evolution of financial globalization in emerging markets using alternative measures, and find that, in the 2000s, financial globalization has grown only marginally and international portfolio diversification has been limited and declining over time. The paper revisits the empirical literature on the implications of financial globalization for local market deepening, international risk diversification, financial contagion, and financial dollarization, and finds them to be rather limited. Whereas financial globalization has indeed fostered domestic market deepening in good times, it has yielded neither the dividends of consumption smoothing (in line with limited portfolio diversification) nor the costs of amplifying global financial shocks. In turn, financial de-dollarization has largely reflected the undoing of financial offshoring and the valuation effects of real appreciation.Publication Uganda Economic Update : Bridges Across Borders - Unleashing Uganda's Regional Trade Potential(Washington, DC, 2013-02)Despite having one of the world's highest rates of population growth, Uganda has an impressive record of economic growth and poverty reduction. Over a period of approximately 20 years, from the 1990s until around 2010, the average annual rate of economic growth stood at around 7 percent. During this same period, the proportion of the population living below the poverty line declined from 56 percent in 1992 to 24 percent in FY10. Uganda needs to sustain its efforts to deepen regional integration as a means of facilitating greater trade opportunities, but primary agenda remains it its own hands. The first point of action is to address constraints to productivity growth in sectors that have the highest potential for regional expansion, including the agriculture, manufacturing and services sectors. Uganda must advocate by setting an example by removing its own non-tariff barriers (NTB) as a means of encouraging neighboring countries. However, it also needs to use its position to persuade the coastal countries to do their part, since they will also benefit from such programs. In addition, Uganda must seize every opportunity to promote peace and tranquility in the Great Lakes regions.

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 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 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 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 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.
