Abstract
This paper studies how portfolios with a global investment scope are allocated internationally using a unique micro dataset on U.S. equity mutual funds. While mutual funds have great flexibility to invest globally, they invest in a surprisingly limited number of stocks, around 100. The number of holdings in stocks and countries from a given region declines as the investment scope of funds broadens. This restrictive investment practice has costs. A mean-variance strategy shows unexploited gains from further international diversification. Mutual funds investing globally could achieve better risk-adjusted returns by broadening their asset allocation, including stocks held by more specialized funds within the same mutual fund family (company). This investment pattern is not explained by lack of information or instruments, transaction costs, or a better ability of global funds to minimize negative outcomes. Instead, industry practices related to organizational factors seem to play an important role.

Publication Geopolitics and the World Trading System(Washington, DC: World Bank, 2024-12-23)Until the beginning of this century, the GATT/WTO system worked. Economic research provided a compelling explanation. It showed that if governments maximize the well-being of their own countries broadly defined, GATT/WTO principles would facilitate mutually beneficial cooperation over their trade policy choices. Now heightened geopolitical rivalry seems to have undermined the WTO. A simple transposition of the previous rationalization suggests that geopolitics and trade cooperation are not compatible. The paper shows that this is only true if rivalry eclipses any consideration of own-country well-being. In all other circumstances, there are gains from trade cooperation even with geopolitics. Furthermore, the WTO’s relevance is in question only if it adheres too rigidly to its existing rules and norms. Through measured adaptation to the geopolitical imperative, the WTO can continue to thrive as a forum for multilateral trade cooperation in the age of geopolitics.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 Global Socio-economic Resilience to Natural Disasters(Washington, DC: World Bank, 2025-05-22)Most disaster risk assessments use damages to physical assets as their central metric, often neglecting distributional impacts and the coping and recovery capacity of affected people. To address this shortcoming, the concepts of well-being losses and socio-economic resilience—the ability to experience asset losses without a decline in well-being—have been proposed. This paper uses microsimulations to produce a global estimate of well-being losses from, and socio-economic resilience to, natural disasters, covering 132 countries. On average, each $1 in disaster-related asset losses results in well-being losses equivalent to a $2 uniform national drop in consumption, with significant variation within and across countries. The poorest income quintile within each country incurs only 9% of national asset losses but accounts for 33% of well-being losses. Compared to high-income countries, low-income countries experience 67% greater well-being losses per dollar of asset losses and require 56% more time to recover. Socio-economic resilience is uncorrelated with exposure or vulnerability to natural hazards. However, a 10 percent increase in GDP per capita is associated with a 0.9 percentage point gain in resilience, but this benefit arises indirectly—such as through higher rate of formal employment, better financial inclusion, and broader social protection coverage—rather than from higher income itself. This paper assess ten policy options and finds that socio-economic and financial interventions (such as insurance and social protection) can effectively complement asset-focused measures (e.g., construction standards) and that interventions targeting low-income populations usually have higher returns in terms of avoided well-being losses per dollar invested.Publication From Patriarchy to Policy(Washington, DC: World Bank, 2025-05-29)Legal institutions play an important role in shaping gender equality in economic domains, from inheritance to labor markets. But where do gender equal laws come from? Using cross-country data on social norms and legal equality, this paper investigates the socio-cultural roots of gender inequity in the legal system and its implications for female labor force participation. To identify the impact of social norms, the analysis uses an empirical strategy that exploits pre-modern differences in ancestral patriarchal culture as an instrument for present-day gender norms. The findings show that ancestral patriarchal culture is a strong predictor of contemporary norms, and conservative social norms are associated with more gender inequality in the de jure legal framework, the de facto implementation of laws, and the labor market. The paper presents evidence for a political selection mechanism linking norms to laws: countries with more conservative norms elect political leaders who are more hostile to gender equality, who then pass less progressive legislation. The results highlight the cultural roots and political drivers of legalized gender inequality.

Publication International Asset Allocations and Capital Flows : The Benchmark Effect(World Bank, Washington, DC, 2014-05)This paper studies channels through which well-known benchmark indexes impact asset allocations and capital flows across countries. The study uses unique monthly micro-level data of benchmark compositions and mutual fund investments during 1996-2012. Benchmarks have important effects on equity and bond mutual fund portfolios across funds with different degrees of activism. Benchmarks explain, on average, around 70 percent of country allocations and have significant impact even on active funds. Benchmark effects are important after controlling for industry, macroeconomic, and country-specific, time-varying effects. Reverse causality does not drive the results. Exogenous, pre-announced changes in benchmarks result in movements in asset allocations mostly when these changes are implemented (not when announced). By impacting country allocations, benchmarks affect capital flows across countries through direct and indirect channels, including contagion. They explain apparently counterintuitive movements in capital flows, generating outflows from countries when upgraded and with large market capitalization and better relative performance.Publication Information Asymmetries and Institutional Investor Mandates(2011-03-01)The preference among foreign institutional investors for large firms is widely documented. This paper deepens our understanding of international investments by providing evidence that foreign institutional investors with broader investment scopes prefer to invest in firms where they are less prone to information disadvantages than more specialized ones. In other words, there is heterogeneity in how information asymmetries affect investors' portfolio choices. Theoretically, a model with costly information and short-selling constraints shows that the broader the investor's mandate, the smaller the incentives to gather and process costly information. Empirically, an analysis of the mutual fund industry in the United States supports this hypothesis.Publication On the International Transmission of Shocks : Micro-Evidence from Mutual Fund Portfolios(World Bank, Washington, DC, 2012-05)Using micro-level data on mutual funds from different financial centers investing in equity and bonds, this paper analyzes how investors and managers behave and transmit shocks across countries. The paper shows that the volatility of mutual fund investments is quantitatively driven by investors through injections of capital into, or redemptions out of, each fund, and by managers changing the country weights and cash in their portfolios. Both investors and managers respond to returns and crises, and substantially adjust their investments accordingly. These mechanisms generated large capital reallocations during the global financial crisis. Their behavior tends to be pro-cyclical, reducing their exposure to countries experiencing crises and increasing it when conditions improve. Managers actively change country weights over time, although there is significant short-run "pass-through," meaning that price changes affect country weights. Consequently, capital flows from mutual funds do not seem to stabilize markets and instead expose countries to foreign shocks.Publication Mutual Fund Investment in Emerging Markets : An Overview(Washington, DC: World Bank, 2001-05)International mutual funds are key contributors to the globalization of financial markets and one of the main sources of capital flows to emerging economies. Despite their importance in emerging markets, little is known about their investment allocation and strategies. This article provides an overview of mutual fund activity in emerging markets. It describes their size, asset allocation, and country allocation and then focuses on their behavior during crises in emerging markets in the 1990s. It analyzes data at both the fund-manager and fund-investor levels. Due to large redemptions and injections, funds' flows are not stable. Withdrawals from emerging markets during recent crises were large, which is consistent with the evidence on financial contagion.Publication Deconstructing Herding : Evidence from Pension Fund Investment Behavior(2011-06-01)Pension funds have been expected to invest in a wide range of securities and provide liquidity to domestic capital markets since they are the most sophisticated investors, with plenty of resources to gather private information and manage portfolios professionally. However, by analyzing unique, monthly asset-level data from the pioneer case of Chile, this paper shows that pension funds tend to herd. This is consistent with pension funds copying each other in their investment strategies as a way to extract information, boost returns, and reduce risk. The authors compute measures of herding across asset classes (equities, government bonds, and private sector bonds) and at different pension fund industry levels. The results show that pension funds herd more in assets for which they have less market information and when risk increases. Moreover, herding is more prevalent across funds that narrowly compete with each other, that is, when comparing funds of the same type across pension fund administrators. There is much less herding within pension fund administrators and across pension fund administrators as a whole. This herding pattern is consistent with incentives for managers to be close to industry benchmarks, which might be driven by both market forces and regulation.

Publication Geothermal Handbook(World Bank, Washington, DC, 2012-06)Developing countries face multiple and complex challenges in securing affordable and reliable energy supplies to support sustainable economic development. These challenges can be addressed by increased access to modern energy infrastructure, enhanced energy security through supply diversification, and transition to low carbon paths to meet rising energy demands. There is broad consensus that renewable energy has a major role to play in addressing these challenges. In recent years, support for renewable energy investment has become a mainstream activity for multilateral development banks and their clients. The World Bank, for instance, has supported geothermal development in Africa, Asia, Europe, and Latin America. Global analytical work and technical assistance on clean energy are also one of the major program areas of the Energy Sector Management Assistance Program (ESMAP). This handbook is dedicated to geothermal energy as a source of electric power for developing countries. Many developing countries are endowed with substantial geothermal resources that could be more actively put to use. On top of the benefits stemming from its renewable nature, geothermal energy has several additional advantages, including the provision of stable and reliable power at a relatively low cost, around the clock, and with few operational or technological risks.Publication Compendium of International and National Legal Frameworks on Sexual Harassment in the Workplace(World Bank, Washington, DC, 2019-12)Sexual Harassment in the Workplace (SHWP) is a universal and widespread phenomenon that affects millions of women of all social strata worldwide. It is an endemic issue that has gained increased visibility and attention since the beginning of the “#MeToo” movement. In this Compendium on International and National Legal Frameworks on Sexual Harassment in the Workplace (the “Compendium”), SHWP is understood as a gender-specific form of violence, commonly directed against women and occurring in employment or the workplace. It includes requests for sexual favors, unwelcome sexual advances or other sexual conduct, whether physical or verbal, which involves a “quid pro quo” aspect (e.g. request for sexual favors used to make employment decisions) and/or creates an intimidating, hostile, toxic, humiliating or offensive working environment. As one of the pervasive expressions of gender-based violence, it reflects discriminatory social norms, stereotypes, impunity and gender inequality. SHWP is viewed as a development challenge and has high economic and social costs. Despite its serious implications for women, employers and society at large, the behavior is widely accepted and minimized. The Compendium provides a survey of the key international and regional instruments as well as national legislation as they relate to SHWP.Publication Business Ready 2024(Washington, DC: World Bank, 2024-10-03)Business Ready (B-READY) is a new World Bank Group corporate flagship report that evaluates the business and investment climate worldwide. It replaces and improves upon the Doing Business project. B-READY provides a comprehensive data set and description of the factors that strengthen the private sector, not only by advancing the interests of individual firms but also by elevating the interests of workers, consumers, potential new enterprises, and the natural environment. This 2024 report introduces a new analytical framework that benchmarks economies based on three pillars: Regulatory Framework, Public Services, and Operational Efficiency. The analysis centers on 10 topics essential for private sector development that correspond to various stages of the life cycle of a firm. The report also offers insights into three cross-cutting themes that are relevant for modern economies: digital adoption, environmental sustainability, and gender. B-READY draws on a robust data collection process that includes specially tailored expert questionnaires and firm-level surveys. The 2024 report, which covers 50 economies, serves as the first in a series that will expand in geographical coverage and refine its methodology over time, supporting reform advocacy, policy guidance, and further analysis and research.Publication World Development Report 2011(World Bank, 2011)The 2011 World development report looks across disciplines and experiences drawn from around the world to offer some ideas and practical recommendations on how to move beyond conflict and fragility and secure development. The key messages are important for all countries-low, middle, and high income-as well as for regional and global institutions: first, institutional legitimacy is the key to stability. When state institutions do not adequately protect citizens, guard against corruption, or provide access to justice; when markets do not provide job opportunities; or when communities have lost social cohesion-the likelihood of violent conflict increases. Second, investing in citizen security, justice, and jobs is essential to reducing violence. But there are major structural gaps in our collective capabilities to support these areas. Third, confronting this challenge effectively means that institutions need to change. International agencies and partners from other countries must adapt procedures so they can respond with agility and speed, a longer-term perspective, and greater staying power. Fourth, need to adopt a layered approach. Some problems can be addressed at the country level, but others need to be addressed at a regional level, such as developing markets that integrate insecure areas and pooling resources for building capacity Fifth, in adopting these approaches, need to be aware that the global landscape is changing. Regional institutions and middle income countries are playing a larger role. This means should pay more attention to south-south and south-north exchanges, and to the recent transition experiences of middle income countries.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.
