Abstract
The current account can be understood as the outcome of investment decisions made by domestic and foreign investors. These decisions can be decomposed into a portfolio rebalancing and a portfolio growth component. This paper provides empirical evidence of the importance of portfolio rebalancing for the dynamics of the current account. The authors evaluate the predictions of a partial-equilibrium model of the current account with dynamic portfolio choices, in which portfolio rebalancing is driven by changes in investment opportunities. Using data for the United States and Japan, the authors find evidence supporting innovations in investment opportunities as an important mechanism to explain international capital flows.

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.

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 It’s Not (Just) the Tariffs: Rethinking Non-Tariff Measures in a Fragmented Global Economy(Washington, DC: World Bank, 2025-10-22)As tariffs have declined, non-tariff measures (NTMs) have become central to trade policy, especially in high-income countries and regulated sectors like food and green technologies. Although NTMs may serve legitimate goals, they could also sort countries and firms into or out of markets based on compliance capacity and differences in product mix. Documenting recent advances in the estimation of ad valorem equivalents (AVEs), this paper uncovers new patterns of use and exposure of NTMs. High-income countries rely more heavily on NTMs relative to tariffs, while low- and middle-income countries face steeper AVEs on their exports. Firm-level evidence shows that NTMs disproportionately affect smaller firms, leading to market exit and concentration. Poorly designed NTMs can harm productivity and welfare, while coordinated, capacity-aware use can deliver inclusive outcomes. Policy design, transparency, and diagnostics must evolve to reflect the growing role—and risks—of NTMs in a fragmented global trade landscape.

Publication The Growing Role of the Euro in Emerging Market Finance(World Bank, Washington, DC, 2007-11)More than eight years after the introduction of the euro, impacts on developing countries have been relatively modest. Overall, the euro has become much more important in debt issuance than in official foreign exchange reserve holdings. The former has benefited from the creation of a large set of investors for which the euro is the home currency, while demand for euro reserves has been held back by the dominance of the dollar as a vehicle and intervention currency, and the greater liquidity of the market for US treasury securities. Fears of further dollar decline may fuel some shifts out of dollars into euros, however, with the potential for a period of financial instability.Publication India Economic Update, September 2012(Washington, DC, 2012-09)Real gross domestic product (GDP) growth has slowed to a nine year low of 6.5 percent for FY2011-12, from 8.4 percent in the two previous years. The slowdown was most pronounced in the industrial sector, and more specifically in manufacturing and mining. In the quarter ending in June 2012, industrial output growth as measured by the Index of Industrial Production (IIP) has been negative. The contraction was particularly pronounced in the production of capital goods, which is in line with falling investment demand on the expenditure side of the National Accounts. The current account deficit reached a record 4.2 percent of GDP in FY2011-12, because of decelerating export growth and high crude prices. Merchandise exports grew by 41 percent in September 2011, but their growth slowed to 2 percent by August 2012 (measured as 12-months cumulative exports compared with the same 12 months of the previous year). Inflation reached 7.6 percent in August 2012. This represents a marked slowdown since September 2011, but there has been an uptick in food prices in recent months. Also, higher domestic prices for fuel, which are necessary to rein in spending on subsidies, will contribute to inflationary pressure. Inflation is therefore expected to reach 8 percent at end-March 2013. Real GDP growth is forecast to reach around 6.0 percent in FY2012-13, after 5.3 percent growth Q4 of FY2011-12 and 5.5 percent growth in Q1 of FY2012-13. The slowdown is at least partly caused by structural problems. These include power shortages, which are partly caused by the financial difficulties facing the electricity sector as discussed in the special topic section of this update, the corruption scandals that have hit the mining and telecom sectors, investor uncertainty because of pending changes in legislation (mining, taxes, land acquisition), and the tightening constraints of land and infrastructure. Tighter macroeconomic policies, slow growth in the core Organization for Economic Co-operation and Development (OECD) countries, and worries about another global recession also weigh on growth. Important signals to revive domestic growth drivers to lift sentiment more than produce instant efficiency gains could come from reforms recently announced and, more importantly, the reform of direct taxes, the implementation of the long-delayed Goods and Services Tax (GST), and passage of the land acquisition and mining bills. This update also looks closely at two important topics for medium- and long-term growth, namely India's Right to Education (RTE) Act, which aims to shape elementary education, and the financial difficulties in the Indian power sector.Publication Philippines Quarterly Update, June 2010(Washington, DC, 2010-06)The Philippines economy posted robust growth in early 2010, in part due to large one-off factors. As did many countries in the region, the Philippines benefited from a strong rebound in global trade. Manufacturing and investment activity expanded briskly as a result. Private consumption continued to expand, as consumer confidence improved. Growth also benefited from election-related spending. Expansionary (and now pro-cyclical) fiscal policy continued to support growth. Despite a withdrawal of liquidity-enhancing measures and a stronger peso, a closing output gap meant that monetary policy remained accommodative. A World Bank study of Philippines migration pattern during the global recession reveals that deployment of overseas foreign workers (OFWs) actually accelerated during the crisis. Partly this reflected the fact that the top OFW destinations were not as affected as the rest of the world. The most affected OFWs were males, production workers (especially construction workers) and new hires. By contrast, females, services workers, seafarers and rehires proved resilient to the crisis or even benefited from it. Globally, less tolerance towards weak public finances is expected, raising the need to introduce a credible medium-term fiscal consolidation plan for the Philippines. Running a pro-cyclical fiscal policy with relatively high debt and limited fiscal space-as undertaken in the first-half of 2010-raises risks and should be reverted. Credibility towards such a goal could be achieved, for example, by designing a comprehensive multi-year reform package. As the output gap closes, the accommodative monetary policy introduced in 2008 would need to be gradually unwound, starting by reaching a broadly neutral stance in 2010. An increase in policy rates currently negative or slightly positive could achieve such a goal.Publication The Potential Impact of the Global Financial Crisis on World Trade(2009-11-01)This paper models the global financial crisis as a combination of shocks to global housing markets and sharp increases in risk premia of firms, households and international investors in a global economic model. The model has six sectors of production and trade in 15 major economies and regions. The paper shows that the shocks observed in financial markets can be used to generate the severe economic contraction in global trade and production experienced in 2009. In particular the distinction between the production and trade of durable and non durable goods plays a key role in explaining the much larger contraction in trade than GDP experienced by most economies. The paper explores the implications of the large increase in fiscal deficits and the implications of a global trade war in response to the financial crisis.Publication Global Economic Prospects : Financial Markets Outlook, June 2014(World Bank Group, Washington, DC, 2014-06)External financing conditions for developing countries have been remarkably favorable in recent months, reflecting expectations of a more drawn-out period of monetary policy accommodation in high-income countries and some narrowing of external vulnerabilities. Additional easing by the European Central Bank, combined with prospects of modest growth and stable inflation in the United States ( Goldilocks recovery ), helped pull down bond yields and volatility worldwide. These benign conditions currently provide support to capital inflows and activity across developing countries, but could at the same time increase the risk of greater and potentially more abrupt market adjustments ahead. Despite some reduction of current account deficits in several developing countries, many remain vulnerable to sudden shifts in investors sentiment and capital outflows. Following a brief period of market turmoil at the start of the year, global financing conditions have eased consider-ably from March to June. Bond spreads for developing countries (i.e. yield difference with 10-year U.S. Treasury bonds) have narrowed, bringing down average borrowing costs to their lowest level since the spring of 2013. Stock markets have also recovered rapidly from a significant sell-off in January/February, despite rising geopolitical tensions and evidence of disappointing activity in the first quarter of the year. As presented in the June 2014 edition of Global Economic Prospects, a more favorable global environment is reflected in upward revisions to capital inflow forecasts for developing countries, now projected to remain broad-ly stable as a percentage of GDP in 2014 and 2015, at around 5.6 percent, before declining again in 2016, to 5.1 percent. While baseline forecasts assume an orderly in-crease in long-term interest rates in high-income countries, the risk of more abrupt adjustments from current low levels has recently increased. Escalating geopolitical tensions or financial stress in some developing countries could also potentially trigger a sudden re-pricing of risk. Despite the recent narrowing of current account deficits in some developing countries, many remain vulnerable to a sharp increase in borrowing costs and/or significant currency depreciations, which could put additional strain on corporate and bank balance sheets.

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 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 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 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 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.
