Abstract
Average incomes in the poorest two quintiles on average increase at the same rate as overall average incomes. This is because, in a global data set spanning 121 countries over the past four decades, changes in the share of income of the poorest quintiles are uncorrelated with changes in average income. The variation in changes in quintile shares is also small relative to the variation in growth in average incomes, implying that the latter accounts for most of the variation in income growth in the poorest quintiles. In addition, we find little evidence that changes in the bottom quintile shares are correlated with country-level factors that are typically considered as important determinants for growth in average incomes or for changes in inequality. This evidence confirms the central importance of economic growth for improvements in living standards at the low end of the income distribution. It also illustrates the difficulty of identifying specific macroeconomic policies that are significantly associated with the growth rates of those in the poorest quintiles relative to everyone else.

Publication Growth Still Is Good for the Poor(World Bank, Washington, DC, 2013-08)Incomes in the poorest two quintiles on average increase at the same rate as overall average incomes. This is because, in a global dataset spanning 118 countries over the past four decades, changes in the share of income of the poorest quintiles are generally small and uncorrelated with changes in average income. The variation in changes in quintile shares is also small relative to the variation in growth in average incomes, implying that the latter accounts for most of the variation in income growth in the poorest quintiles. These findings hold across most regions and time periods and when conditioning on a variety of country-level factors that may matter for growth and inequality changes. This evidence confirms the central importance of economic growth for poverty reduction and illustrates the difficulty of identifying specific macroeconomic policies that are significantly associated with the relative growth rates of those in the poorest quintiles.Publication Growth, Inequality, and Social Welfare : Cross-Country Evidence(World Bank, Washington, DC, 2014-04)Social welfare functions that assign weights to individuals based on their income levels can be used to document the relative importance of growth and inequality changes for changes in social welfare. In a large panel of industrial and developing countries over the past 40 years, most of the cross-country and over-time variation in changes in social welfare is due to changes in average incomes. In contrast, the changes in inequality observed during this period are on average much smaller than changes in average incomes, are uncorrelated with changes in average incomes, and have contributed relatively little to changes in social welfare.Publication Growth is Good for the Poor(World Bank, Washington, DC, 2001-04)When average income rises, the average incomes of the poorest fifth of society rise proportionately. This is a consequence of the strong empirical regularity that the share of income accruing to the bottom quintile does not vary systematically with average income. The authors document this empirical regularity in a sample of 92 countries spanning the past four decades and show that it holds across regions, periods, income levels, and growth rates. The authors next ask whether the factors that explain cross-country differences in the growth rates of average incomes have differential effects on the poorest fifth of society. They find that several determinants of growth--such as good rule of law, opennness to international trade, and developed financial markets--have little systematic effect on the share of income that accrues to the bottom quintile. Consequently, these factors benefit the poorest fifth of society as much as everyone else. Thee is some weak evidence that stabilization from high inflation and reductions in the overall size of government not only increase growth but also increase the income share of the poorest fifth in society. Finally, the authors examine several factors commonly thought to disproportionately benefit the poorest in society, but find little evidence of their effects. The absence of robust findings emphasizes that relatively little is known about the broad forces that account for the cross-country and intertemporal variation in the share of income accruing to the poorest fifth of society.Publication Trade, Growth, and Poverty(World Bank, Washington, DC, 2001-06)The evidence from individual cases and from cross-country analysis supports the view that globalization leads to faster growth and poverty reduction in poor countries. To determine the effect of globalization on growth, poverty, and inequality, the authors first identify a group of developing countries that are participating more in globalization. China, India, and several other large countries are part of this group, so well over half the population of the developing world lives in these globalizing economies. Over the past 20 years, the post-1980 globalizers have seen large increases in trade and significant declines in tariffs. Their growth rates accelerated between the 1970s and the 1980s and again between the 1980s and the 1990s, even as growth in the rich countries and the rest of the developing world slowed. The post-1980 globalizers are catching up to the rich countries, but the rest of the developing world (the non-globalizers) is falling further behind. Next, the authors ask how general these patterns are, using regressions that exploit within-country variations in trade and growth. After controlling for changes in other policies and addressing endogeneity with internal instruments, they find that trade has a strong positive effect on growth. Finally, the authors examine the effects of trade on the poor. They find little systematic evidence of a relationship between changes in trade volumes (or any other measure of globalization they consider) and changes in the income share of the poorest-or between changes in trade volumes and changes in household income inequality. They conclude, therefore, that the increase in growth rates that accompanies expanded trade translates on average into proportionate increases in incomes of the poor. Absolute poverty in the globalizing developing economies has fallen sharply in the past 20 years. The evidence from individual cases and from cross-country analysis supports the view that globalization leads to faster growth and poverty reduction in poor countries.Publication Institutions, Trade, and Growth : Revisiting the Evidence(World Bank, Washington, DC, 2003-03)Several recent papers have attempted to identify the partial effects of trade integration and institutional quality on long-run growth using the geographical determinants of trade and the historical determinants of institutions as instruments. The authors show that many of the specifications in these papers are weakly identified despite the apparently good performance of the instruments in first-stage regressions. Consequently, they argue that the cross-country variation in institutions, trade, and their geographical and historical determinants is not very informative about the partial effects of these variables on long-run growth.

Publication Empowerment in Practice : From Analysis to Implementation(Washington, DC: World Bank, 2006)This book represents an effort to present an easily accessible framework to readers, especially those for whom empowerment remains a puzzling development concern, conceptually and in application. The book is divided into two parts. Part 1 explains how the empowerment framework can be used for understanding, measuring, monitoring, and operationalizing empowerment policy and practice. Part 2 presents summaries of each of the five country studies, using them to discuss how the empowerment framework can be applied in very different country and sector contexts and what lessons can be learned from these test cases. While this book can offer only a limited empirical basis for the positive association between empowerment and development outcomes, it does add to the body of work supporting the existence of such a relationship. Perhaps more importantly, it also provides a framework for future research to test the association and to prioritize practical interventions seeking to empower individuals and groups.Publication Natural Disasters, Poverty and Inequality(Taylor and Francis, 2021-10-28)Conventional risk assessments underestimate the human and macroeconomic costs of disasters, leading to inefficient risk management strategies. This happens because conventional assessments focus on asset losses, neglecting important relationships between vulnerability and development. When affected by a hazard, poor households take longer to recover from disasters and are more likely to face long-term consequences. Forced to manage trade-offs between essential consumption and reconstruction, these households are more likely to face persistent health or education costs. This chapter proposes a review of existing research into the natural disaster-poverty-inequality nexus and the various metrics that can be used to measure disaster impacts, such as recovery times, economic (income or consumption) losses, poverty incidence, inequality, and welfare or well-being losses. Each of these metrics provides a different perspective on disaster costs and suggest different spatial and sectoral priorities for action. Focusing on the concepts of well-being losses and socioeconomic resilience, this chapter shows how more comprehensive accounting of disaster impacts can better inform disaster risk management and climate change adaptation strategies and support their integration into development and poverty-reduction policies.Publication World Development Report 2004(World Bank, 2003)Too often, services fail poor people in access, in quality, and in affordability. But the fact that there are striking examples where basic services such as water, sanitation, health, education, and electricity do work for poor people means that governments and citizens can do a better job of providing them. Learning from success and understanding the sources of failure, this year’s World Development Report, argues that services can be improved by putting poor people at the center of service provision. How? By enabling the poor to monitor and discipline service providers, by amplifying their voice in policymaking, and by strengthening the incentives for providers to serve the poor. Freedom from illness and freedom from illiteracy are two of the most important ways poor people can escape from poverty. To achieve these goals, economic growth and financial resources are of course necessary, but they are not enough. The World Development Report provides a practical framework for making the services that contribute to human development work for poor people. With this framework, citizens, governments, and donors can take action and accelerate progress toward the common objective of poverty reduction, as specified in the Millennium Development Goals.Publication The Design and Sustainability of Renewable Energy Incentives : An Economic Analysis(Washington, DC: World Bank, 2015)Rapid urbanization and economic growth, new demographic trends, and climate change are key challenges that developing countries must face as they strive to meet growing energy demand. The main objectives of this study are to offer: (a) a global taxonomy of the economic and financial incentives provided by renewable support schemes and (b) an economic modeling of the sustainability and affordability of such support schemes. In an attempt to contribute to the lively debate, this study provides a global taxonomy of the economic and financial incentives provided by renewable energy (RE) support schemes. It summarizes economic models of the sustainability and affordability of such support schemes, alongside operational advice on how the regulatory design may need to be modified to minimize the impact on the budget and be affordable to the poor, as well as how to identify and fill the financing gap. This analytical framework: (a) differentiates and illustrates tradeoffs among local, regional, and national impacts, in the short and long run; (b) captures distributional impacts (since subsidies to cover the incremental costs of RE may have very different beneficiaries); and (c) captures externalities and compares (where possible) alternative projects based on equivalent output and cost (comparing, for example, RE and energy efficiency projects against those using fossil fuels). The report is organized as follows: chapter one gives introduction. Chapter two presents the analytical framework that underpins the case studies, and provides the background for the principal research hypothesis of this report, which is better attention to the principles of economic analysis and market efficiency leads to more sustainable and effective policies. Chapter s three to ten present country case studies for Vietnam, Indonesia, Sri Lanka, South Africa, Tanzania, Egypt, Brazil, and Turkey. The conclusions of the study are presented in chapter eleven.Publication Income Mobility, Income Risk, and Welfare(Published by Oxford University Press on behalf of the World Bank, 2019-06)This paper presents a framework for the quantitative analysis of individual income dynamics, mobility, and welfare, with ex ante identical individuals facing a stochastic income process and market incompleteness, implying that they are unable to insure against persistent shocks to income. We show how the parameters of the income process can be estimated using repeated cross-sectional data with a short panel dimension and use a simple consumption-saving model for quantitative analysis of mobility and welfare. Our empirical application, using data on individual incomes from Mexico, provides striking results. Most of the measured income mobility is driven by measurement error or transitory income shocks and is therefore (almost) welfare neutral. Only a small part of measured income mobility is due to either welfare-reducing income risk or welfare-enhancing catching-up of low-income individuals with high-income individuals, both of which, nevertheless, have economically significant effects on social welfare. Strikingly, roughly half of the mobility that cannot be attributed to measurement error or transitory income shocks is driven by welfare-reducing persistent income shocks. Decomposing mobility into its fundamental components is thus crucial from the standpoint of welfare evaluation.
