Abstract
This paper examines the impact of bank regulations, concentration, inflation, and national institutions on bank net interest margins using data from over 1,400 banks across 72 countries while controlling for bank-specific characteristics. The data indicate that tighter regulations on bank entry and bank activities boost net interest margins. Inflation also exerts a robust, positive impact on bank margins. While concentration is positively associated with net interest margins, this relationship breaks down when controlling for regulatory impediments to competition and inflation. Furthermore, bank regulations become insignificant when controlling for national indicators of economic freedom or property rights protection, while these institutional indicators robustly explain cross-bank net interest margins. So, bank regulations cannot be viewed in isolation. They reflect broad, national approaches to private property and competition.

Publication The Asymmetric Bank Distress Amplifier of Recessions(Washington, DC: World Bank, 2025-07-11)One defining feature of financial crises, evident in U.S. and international data, is asymmetric bank distress—concentrated losses on a subset of banks. This paper proposes a model in which shocks to borrowers’ productivity dispersion lead to asymmetric bank losses. The framework exhibits a “bank distress amplifier,” exacerbating economic downturns by causing costly bank failures and raising uncertainty about the solvency of banks, thereby pushing banks to deleverage. Quantitative analysis shows that the bank distress amplifier doubles investment decline and increases the spread by 2.5 times during the Great Recession compared to a standard financial accelerator model. The mechanism helps explain how a seemingly small shock can sometimes trigger a large crisis.Publication From Tailwinds to Headwinds(Washington, DC: World Bank, 2025-07-10)The first quarter of the twenty-first century has been transformative for emerging market and developing economies (EMDEs). These economies now account for about 45 percent of global GDP, up from about 25 percent in 2000, a trend driven by robust collective growth in the three largest EMDEs—China, India, and Brazil (the EM3). Collectively, EMDEs have contributed about 60 percent of annual global growth since 2000, on average, double the share during the 1990s. Their ascendance was powered by swift global trade and financial integration, especially during the first decade of the century. Interdependence among these economies has also increased markedly. Today, nearly half of goods exports from EMDEs go to other EMDEs, compared to one-quarter in 2000. As cross-border linkages have strengthened, business cycles among EMDEs and between EMDEs and advanced economies have become more synchronized, and a distinct EMDE business cycle has emerged. Cross-border business cycle spillovers from the EM3 to other EMDEs are sizable, at about half of the magnitude of spillovers from the largest advanced economies (the United States, the euro area, and Japan). Yet EMDEs confront a host of headwinds at the turn of the second quarter of the century. Progress implementing structural reforms in many of these economies has stalled. Globally, protectionist measures and geopolitical fragmentation have risen sharply. High debt burdens, demographic shifts, and the rising costs of climate change weigh on economic prospects. A successful policy approach to accelerate growth and development should focus on boosting investment and productivity, navigating a difficult external environment, and enhancing macroeconomic stability.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 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 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 Bank Concentration and Crises(World Bank, Washington, DC, 2003-05)The authors study the impact of bank concentration, regulations, and national institutions on the likelihood of suffering a systemic banking crisis. Using data on 79 countries over the period 1980-97, they find that crises are less likely (1) in more concentrated banking systems, (2) in countries with fewer regulatory restrictions on bank competition and activities, and (3) in economies with better institutions, that is, institutions that encourage competition and support private property rights.Publication Bank Activity and Funding Strategies : The Impact on Risk and Returns(2009-02-01)This paper examines the implications of bank activity and short-term funding strategies for bank risk and returns using an international sample of 1,334 banks in 101 countries leading up to the 2007 financial crisis. Expansion into non-interest income generating activities such as trading increases the rate of return on assets, and it may offer some risk diversification benefits at very low levels. Non-deposit, wholesale funding, by contrast, lowers the rate of return on assets, although it can offer some risk reduction at commonly observed low levels of non-deposit funding. A sizeable proportion of banks, however, attract most of their short-term funding in the form of non-deposits at a cost of enhanced bank fragility. Overall, banking strategies that rely prominently on generating non-interest income or attracting non-deposit funding are very risky, which is consistent with the demise of the U.S. investment banking sector.Publication Governance and Bank Valuation(World Bank, Washington, D.C., 2004-02)Which public policies and ownership structures enhance the governance of banks? The authors construct a new database on the ownership of banks internationally and then assess the ramifications of ownership, shareholder protection laws, and supervisory and regulatory policies on bank valuations. Except in a few countries with very strong shareholder protection laws, banks are not widely held, but rather families or the state tend to control banks. The authors find that: (i) Larger cash flow rights by the controlling owner boosts valuations; (ii) Stronger shareholder protection laws increase valuations; and (iii) Greater cash flow rights mitigate the adverse effects of weak shareholder protection laws on bank valuations. These results are consistent with the views that expropriation of minority shareholders is important internationally, that laws can restrain this expropriation, and concentrated cash flow rights represent an important mechanism for governing banks. Finally, the evidence does not support the view that empowering official supervisory and regulatory agencies will increase the market valuation of banks.Publication Does Judicial Efficiency Lower the Cost of Credit?(World Bank, Washington, DC, 2003-10)The authors investigate the effect of judicial efficiency on banks' lending spreads for a large cross section of countries. They measure bank interest rate spreads for 106 countries at an aggregate level, and for 32 countries at the level of individual banks. The authors find that-after controlling for a number of other country characteristics-judicial efficiency, in addition to inflation, is the main driver of interest rate spreads across countries. This suggests that in addition to improving the overall macroeconomic climate in a country, judicial reforms, through a better enforcement of legal contracts, are critical to lowering the cost of financial intermediation for households and firms.Publication Bank Regulations Are Changing : For Better or Worse?(World Bank, Washington, DC, 2008-06)This paper presents new and official survey information on bank regulations in 142 countries and makes comparisons with two earlier surveys. The data do not suggest that countries have primarily reformed their bank regulations for the better over the last decade. Following Basel guidelines many countries strengthened capital regulations and official supervisory agencies, but existing evidence suggests that these reforms will not improve bank stability or efficiency. While some countries have empowered private monitoring of banks, consistent with the third pillar of Basel II, there are many exceptions and reversals along this dimension.

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 Sourcebook on the Foundations of Social Protection Delivery Systems(Washington, DC: World Bank, 2020-07-30)The Sourcebook synthesizes real-world experiences and lessons learned of social protection delivery systems from around the world, with a particular focus on social and labor benefits and services. It takes a practical approach, seeking to address concrete “how-to” questions, including: How do countries deliver social protection benefits and services? How do they do so effectively and efficiently? How do they ensure dynamic inclusion, especially for the most vulnerable and needy? How do they promote better coordination and integration—not only among social protection programs but also programs in other parts of government? How can they meet the needs of their intended populations and provide a better client experience? The Sourcebook structures itself around eight key principles that can frame the delivery systems mindset: (1) delivery systems evolve over time, do so in a non-linear fashion, and are affected by the starting point(s); (2) additional efforts should be made to “do simple well”, and to do so from the start rather than trying to remedy by after-the-fact adding-on of features or aspects; (3) quality implementation matters, and weaknesses in the design or structure of any core system element will negatively impact delivery; (4) defining the “first mile” for people interface greatly affects the system and overall delivery, and is most improved when that “first mile” is understood as the weakest link in delivery systems); (5) delivery systems do not operate in a vacuum and thus should not be developed in silos; (6) delivery systems can contribute more broadly to government’s ability to intervene in other sectors, such as health insurance subsidies, scholarships, social energy tariffs, housing benefits, and legal services; (7) there is no single blueprint for delivery systems, but there are commonalities and those common elements constitute the core of the delivery systems framework; (8) inclusion and coordination are pervasive and perennial dual challenges, and they contribute to the objectives of effectiveness and efficiency.Publication Global Economic Prospects, June 2024(Washington, DC: World Bank, 2024-06-11)After several years of negative shocks, global growth is expected to hold steady in 2024 and then edge up in the next couple of years, in part aided by cautious monetary policy easing as inflation gradually declines. However, economic prospects are envisaged to remain tepid, especially in the most vulnerable countries. Risks to the outlook, while more balanced, are still tilted to the downside, including the possibility of escalating geopolitical tensions, further trade fragmentation, and higher-for-longer interest rates. Natural disasters related to climate change could also hinder activity. Subdued growth prospects across many emerging market and developing economies and continued risks underscore the need for decisive policy action at the global and national levels. Global Economic Prospects is a World Bank Group Flagship Report that examines global economic developments and prospects, with a special focus on emerging market and developing economies, on a semiannual basis (in January and June). Each edition includes analytical pieces on topical policy challenges faced by these economies.Publication World Development Report 2008(Washington, DC, 2007)The world's demand for food is expected to double within the next 50 years, while the natural resources that sustain agriculture will become increasingly scarce, degraded, and vulnerable to the effects of climate change. In many poor countries, agriculture accounts for at least 40 percent of GDP and 80 percent of employment. At the same time, about 70 percent of the world's poor live in rural areas and most depend on agriculture for their livelihoods. World Development Report 2008 seeks to assess where, when, and how agriculture can be an effective instrument for economic development, especially development that favors the poor. It examines several broad questions: How has agriculture changed in developing countries in the past 20 years? What are the important new challenges and opportunities for agriculture? Which new sources of agricultural growth can be captured cost effectively in particular in poor countries with large agricultural sectors as in Africa? How can agricultural growth be made more effective for poverty reduction? How can governments facilitate the transition of large populations out of agriculture, without simply transferring the burden of rural poverty to urban areas? How can the natural resource endowment for agriculture be protected? How can agriculture's negative environmental effects be contained? This year's report marks the 30th year the World Bank has been publishing the World Development Report.Publication Guide to the Debt Management Performance Assessment Tool(Washington, DC, 2008-02-05)The purpose of this document is to provide guidance and supplemental information to assist with country assessments of debt management performance, using the Debt Management Performance Assessment (DeMPA) tool. The DeMPA is a methodology used for assessing public debt management performance through a comprehensive set of 15 performance indicators spanning the full range of government Debt Management (DeM) functions. It is based on the principles set out in the International Monetary Fund (IMF) and World Bank guidelines for public debt management, initially published in 2001 and updated in 2003. It is modeled after the Public Expenditure and Financial Accountability (PEFA) framework for performance measurement of public financial management. The DeMPA has been designed to be a user-friendly tool to undertake an assessment of the strengths and weaknesses in government DeM practices. This guide provides additional background and supporting information so that a no specialist in the area of debt management may undertake a country assessment effectively. The guide can be used by assessors in preparing for and undertaking an assessment. It is particularly useful for understanding the rationale for the inclusion of the indicators, the scoring methodology, and the list of supporting documents or evidence required, and the questions that could be asked for the assessment.
