Abstract
The World Bank has been publishing estimates of adjusted net or "genuine" saving since 1999. This measure of saving treats depletion of natural resources as a type of economic depreciation. Hamilton uses recent theoretical results relating growth in saving to growth in future consumption to provide a test of genuine saving using historical data. Did measured genuine saving in 1976, for example, "predict" the observed changes in consumption over subsequent decades? The author tests four alternative measures of saving econometrically. The worst measure, in terms of explained variation, is traditional net saving. Genuine saving adjusted to reflect population growth exhibits the worst fit with theory. Both gross saving and genuine saving perform better, with good concordance with theory, while genuine saving exhibits a moderate advantage in terms of goodness of fit.

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 Resource Discoveries, Learning, and National Income Accounting(World Bank, Washington, DC, 2013-06)Questions about the ultimate size of mineral and energy resource endowments and the degree of fiscal prudence which should be exercised by countries engaged in resource extraction have become central for many developing countries during the recent resource boom. To explore these questions, this paper develops a model of optimal resource extraction and discovery that combines two polar assumptions: (i) that discovering a resource today drives up the cost of future resource discoveries, and (ii) that extracting resources yields knowledge that reduces the cost of discovery. Although the model shows that resource discoveries should be valued at marginal discovery cost in measures of national saving and income, the ultimate size of the resource that can be exploited is the result of the interplay between rising discovery costs and accumulating knowledge. Empirical tests of the model show that the resulting income estimates would be extremely volatile for many extractive economies, owing to the lumpiness of resource discoveries. Two alternative accounting approaches, based on Hicksian concepts, yield more intuitive and less volatile income estimates. The question of fiscal prudence for extractive economies hinges on how optimistic countries are about the risks in future mineral and energy markets, and how far into the future these countries are willing to project optimistic trends when making decisions about how much to consume and how much to save of current resource revenues.Publication Human Capital, Tangible Wealth, and the Intangible Capital Residual(World Bank, Washington, DC, 2013-03)Since income is the return on wealth, the total wealth of any given country should be on the order of 20 times its gross domestic product. Instead the average observed ratio from the balance sheet accounts of the System of National Accounts is a factor of 2.6 to 6.6, depending on whether natural resource stocks are included in the balance sheet. The clear implication is that the System of National Accounts wealth accounts are incomplete, with the most obvious omission being human capital. Estimating the value of human capital using the lifetime income approach for a sample of 13 (mostly high-income) countries yields a mean share of human capital in total wealth of 62 percent -- four times the value of produced capital and 15 times the value of natural capital. But for selected high-income countries in the sample there is still an average of 25 percent of total wealth that is unaccounted -- it is neither produced, nor natural, nor human capital. This residual intangible wealth is arguably the "stock equivalent" of total factor productivity -- the value of assets such as institutional quality and social capital that augment the capacity of produced, natural and human capital to support a stream of consumption into the future.Publication Comprehensive Wealth, Intangible Capital, and Development(2010-10-01)Existing wealth estimates show that in most countries intangible capital is the largest share of total wealth. Intangible capital is calculated as the difference between total wealth and tangible (produced and natural) capital. This paper uses new estimates of total wealth, natural capital, and physical capital for a panel of countries to shed light on the constituents of the intangible capital residual. In a development-accounting framework, the authors show that factors of production are very successful in explaining the variation in output per worker when they use intangible capital instead of human capital as a factor of production. This suggests that intangible capital captures a broad range of assets typically included in the total factor productivity residual. Human capital is an important factor, both in statistical and economic terms, in regressions decomposing intangible capital.Publication The Environment as a Factor of Production(World Bank, Washington, D.C., 2004-04)The authors develop a model of environmental resource use in production with an empirical analysis of how electric power companies consume and bank sulfur dioxide pollution permits. The model considers emissions, fuels, and labor as variable inputs with quasi-fixed inputs of permits and capital. Incorporating information from permit markets allows the authors to distinguish between user costs and asset shadow values. Their findings indicate that firms are holding stocks of pollution permits for reasons other than short-term cost savings. The results also reveal substantial substitution possibilities between emissions, permits stocks, and other factors of production. The authors speculate that anticipated secondary markets for carbon-offset inventories related to the flexibility mechanisms of the Kyoto Protocol will have similar effects for greenhouse-gas emitting firms.Publication Biodiversity and National Accounting(World Bank, Washington, DC, 2013-05)Biodiversity, a property of natural areas, provides a range of benefits to the economy including bioprospecting rents, knowledge and insurance, ecotourism fees, and ecosystem services. Many of these values can be broken out in the System of National Accounts, leading to better estimates of the economic losses when natural areas are degraded or destroyed. Developing countries harbor the great majority of biodiversity, and this diversity provides benefits, including knowledge and carbon sequestration, to the whole world. However, protecting biodiversity is particularly costly for developing countries: the opportunity cost of foregoing development of natural areas exceeds 1 percent of gross domestic product in 58 developing countries, versus only four OECD countries. The Global Environment Facility can offset these costs through grant finance, but annual Global Environment Facility finance and co-finance averages only 8 percent of the opportunity costs faced by low-income countries.

Publication Remarks at the United Nations Biodiversity Conference(World Bank, Washington, DC, 2021-10-12)World Bank Group President David Malpass discussed biodiversity and climate change being closely interlinked, with terrestrial and marine ecosystems serving as critically important carbon sinks. At the same time climate change acts as a direct driver of biodiversity and ecosystem services loss. The World Bank has financed biodiversity conservation around the world, including over 116 million hectares of Marine and Coastal Protected Areas, 10 million hectares of Terrestrial Protected Areas, and over 300 protected habitats, biological buffer zones and reserves. The COVID pandemic, biodiversity loss, climate change are all reminders of how connected we are. The recovery from this pandemic is an opportunity to put in place more effective policies, institutions, and resources to address biodiversity loss.Publication Greater Heights(Washington, DC: World Bank, 2025-03-12)Twenty-seven countries have reached high-income status since 1990. Ten of these are in the Europe and Central Asia region and have joined the European Union. Another 20 in the region have become more prosperous since the 1990s. However, their transition to high-income status has been delayed. These middle-income countries have found that the prospects for growth to high-income status have become even more difficult since the 2007–09 global financial crisis. This reflects partly a slowdown in structural reforms at home and partly the challenges associated with a deterioration in the global environment. The concern has emerged that many countries in the region may be caught in the middle-income trap, a phase in development characterized by a recurring deceleration in growth and by per capita incomes that are systematically below the high-income threshold. To ensure that these countries overcome the obstacles to growth and achieve progress toward high-income status, policy makers need to make the transition from a strategy driven largely by investment to a strategy that is supported by the importation and diffusion of global capital, knowledge, and technology and then to a strategy that complements these with innovation. The report Greater Heights: Growing to High Income in Europe and Central Asia relies on the 3i strategy described in World Development Report 2024—investment, infusion, and innovation—to propose policy options to assist middle-income countries in Europe and Central Asia in the effort to reach high-income status. Drawing on comprehensive empirical analysis, the report offers actionable recommendations that will enable policy makers to advance stronger economic growth across the region. Such a transition will require continued and sustained foundational reform to maximize the drivers of economic growth while pivoting to new transformative reforms to promote the development of more complex economic structures and institutions. These involve the need to discipline incumbents, boost the role of the private sector, strengthen the competitive environment, and reward merit. The emphasis on a strategy driven by innovation is also critically important for those countries that have already attained high-income status.Publication Europe and Central Asia Economic Update, Fall 2024: Better Education for Stronger Growth(Washington, DC: World Bank, 2024-10-17)Economic growth in Europe and Central Asia (ECA) is likely to moderate from 3.5 percent in 2023 to 3.3 percent this year. This is significantly weaker than the 4.1 percent average growth in 2000-19. Growth this year is driven by expansionary fiscal policies and strong private consumption. External demand is less favorable because of weak economic expansion in major trading partners, like the European Union. Growth is likely to slow further in 2025, mostly because of the easing of expansion in the Russian Federation and Turkiye. This Europe and Central Asia Economic Update calls for a major overhaul of education systems across the region, particularly higher education, to unleash the talent needed to reinvigorate growth and boost convergence with high-income countries. Universities in the region suffer from poor management, outdated curricula, and inadequate funding and infrastructure. A mismatch between graduates' skills and the skills employers are seeking leads to wasted potential and contributes to the region's brain drain. Reversing the decline in the quality of education will require prioritizing improvements in teacher training, updated curricula, and investment in educational infrastructure. In higher education, reforms are needed to consolidate university systems, integrate them with research centers, and provide reskilling opportunities for adult workers.Publication Media and Messages for Nutrition and Health(World Bank, Washington, DC, 2020-06)The Lao People’s Democratic Republic (Lao PDR) has experienced rapid and significant economic growth over the past decade. However, poor nutritional outcomes remain a concern. Rates of childhood undernutrition are particularly high in remote, rural, and upland areas. Media have the potential to play an important role in shaping health and nutrition–related behaviors and practices as well as in promoting sociocultural and economic development that might contribute to improved nutritional outcomes. This report presents the results of a media audit (MA) that was conducted to inform the development and production of mass media advocacy and communication strategies and materials with a focus on maternal and child health and nutrition that would reach the most people from the poorest communities in northern Lao PDR. Making more people aware of useful information, essential services and products and influencing them to use these effectively is the ultimate goal of mass media campaigns, and the MA measures the potential effectiveness of media efforts to reach this goal. The effectiveness of communication channels to deliver health and nutrition messages to target beneficiaries to ensure maximum reach and uptake can be viewed in terms of preferences, satisfaction, and trust. Overall, the four most accessed media channels for receiving information among communities in the study areas were village announcements, mobile phones, television, and out-of-home (OOH) media. Of the accessed media channels, the top three most preferred channels were village announcements (40 percent), television (26 percent), and mobile phones (19 percent). In terms of trust, village announcements were the most trusted source of information (64 percent), followed by mobile phones (14 percent) and television (11 percent). Hence of all the media channels, village announcements are the most preferred, have the most satisfied users, and are the most trusted source of information in study communities from four provinces in Lao PDR with some of the highest burden of childhood undernutrition.Publication Economic Recovery(World Bank, Washington, DC, 2021-04-06)World Bank Group President David Malpass spoke about the world facing major challenges, including COVID, climate change, rising poverty and inequality and growing fragility and violence in many countries. He highlighted vaccines, working closely with Gavi, WHO, and UNICEF, the World Bank has conducted over one hundred capacity assessments, many even more before vaccines were available. The World Bank Group worked to achieve a debt service suspension initiative and increased transparency in debt contracts at developing countries. The World Bank Group is finalizing a new climate change action plan, which includes a big step up in financing, building on their record climate financing over the past two years. He noted big challenges to bring all together to achieve GRID: green, resilient, and inclusive development. Janet Yellen, U.S. Secretary of the Treasury, mentioned focusing on vulnerable people during the pandemic. Kristalina Georgieva, Managing Director of the International Monetary Fund, focused on giving everyone a fair shot during a sustainable recovery. All three commented on the importance of tackling climate change.
