World Inequality Report 2018 is the most authoritative and up-to-date account of global trends in inequality. Researched, compiled, and written by a team of the world’s leading economists of inequality, it presents—with unrivaled clarity and depth—information and analysis that will be vital to policy makers and scholars everywhere. Inequality has taken center stage in public debate as the wealthiest people in most parts of the world have seen their share of the economy soar relative to that of others, many of whom, especially in the West, have experienced stagnation. The resulting political and social pressures have posed harsh new challenges for governments and created a pressing demand for reliable data. The World Inequality Lab at the Paris School of Economics and the University of California, Berkeley, has answered this call by coordinating research into the latest trends in the accumulation and distribution of income and wealth on every continent. This inaugural report analyzes the Lab’s findings, which include data from major countries where information has traditionally been difficult to acquire, such as China, India, and Brazil. Among nations, inequality has been decreasing as traditionally poor countries’ economies have caught up with the West. The report shows, however, that inequality has been steadily deepening within almost every nation, though national trajectories vary, suggesting the importance of institutional and policy frameworks in shaping inequality. World Inequality Report 2018 will be a key document for anyone concerned about one of the most imperative and contentious subjects in contemporary politics and economics.

The Cancer in Sub-Saharan Africa volume brings together population-based cancer incidence data from 25 cancer registries in 20 sub-Saharan African countries that are part of the African Cancer Registry Network. The compiled data in this volume, presented and commented upon by covered population and by anatomical site, are of tremendous value to the assessment of the pattern and evolution of cancer in Africa, as a means of elucidating, confirming, and evaluating causes of the disease.

"The paper presents a nontechnical summary of the current state of debate on the measurement and implications of global inequality (inequality between citizens of the world). It discusses the relationship between globalization and global inequality. And it shows why global inequality matters and proposes a scheme for global redistribution. "--World Bank web site.

Perceptions of Africa have changed dramatically. Viewed as a continent of wars, famines and entrenched poverty in the late 1990s, there is now a focus on “Africa rising†? and an “African 21st century.†? Two decades of unprecedented economic growth in Africa should have brought substantial improvements in well-being. Whether or not they did, remains unclear given the poor quality of the data, the nature of the growth process (especially the role of natural resources), conflicts that affect part of the region, and high population growth. Poverty in a Rising Africa documents the data challenges and systematically reviews the evidence on poverty from monetary and nonmonetary perspectives, as well as a focus on dimensions of inequality. Chapter 1 maps out the availability and quality of the data needed to track monetary poverty, reflects on the governance and political processes that underpin the current situation with respect to data production, and describes some approaches to addressing the data gaps. Chapter 2 evaluates the robustness of the estimates of poverty in Africa. It concludes that poverty reduction in Africa may be slightly greater than traditional estimates suggest, although even the most optimistic estimates of poverty reduction imply that more people lived in poverty in 2012 than in 1990. A broad-stroke profile of poverty and trends in poverty in the region is presented. Chapter 3 broadens the view of poverty by considering nonmonetary dimensions of well-being, such as education, health, and freedom, using Sen's (1985) capabilities and functioning approach. While progress has been made in a number of these areas, levels remain stubbornly low. Chapter 4 reviews the evidence on inequality in Africa. It looks not only at patterns of monetary inequality in Africa but also other dimensions, including inequality of opportunity, intergenerational mobility in occupation and education, and extreme wealth in Africa.

World Inequality Report 2022 is the most authoritative and comprehensive account of global trends in inequality, providing cutting-edge information about income and wealth inequality and also pioneering data about the history of inequality, gender inequality, environmental inequalities, and trends in international tax reform and redistribution.

This paper analyzes the extent of income inequality from a global perspective, its drivers, and what to do about it. The drivers of inequality vary widely amongst countries, with some common drivers being the skill premium associated with technical change and globalization, weakening protection for labor, and lack of financial inclusion in developing countries. We find that increasing the income share of the poor and the middle class actually increases growth while a rising income share of the top 20 percent results in lower growth—that is, when the rich get richer, benefits do not trickle down. This suggests that policies need to be country specific but should focus on raising the income share of the poor, and ensuring there is no hollowing out of the middle class. To tackle inequality, financial inclusion is imperative in emerging and developing countries while in advanced economies, policies should focus on raising human capital and skills and making tax systems more progressive.

Eight papers, both theoretical and applied, on the concept of equality of opportunity which says that a society should guarantee its members equal access to advantage regardless of their circumstances, while holding them responsible for turning that access into actual advantage by the application of effort.

Poverty and Shared Prosperity 2016 is the first of an annual flagship report that will inform a global audience comprising development practitioners, policy makers, researchers, advocates, and citizens in general with the latest and most accurate estimates on trends in global poverty and shared prosperity. This edition will also document trends in inequality and identify recent country experiences that have been successful in reducing inequalities, provide key lessons from those experiences, and synthesize the rigorous evidence on public policies that can shift inequality in a way that bolsters poverty reduction and shared prosperity in a sustainable manner. Specifically, the report will address the following questions: • What is the latest evidence on the levels and evolution of extreme poverty and shared prosperity? • Which countries and regions have been more successful in terms of progress toward the twin goals and which are lagging behind? • What does the global context of lower economic growth mean for achieving the twin goals? • How can inequality reduction contribute to achieving the twin goals? • What does the evidence show concerning global and between- and within-country inequality trends? • Which interventions and countries have used the most innovative approaches to achieving the twin goals through reductions in inequality? The report will make four main contributions. First, it will present the most recent numbers on poverty, shared prosperity, and inequality. Second, it will stress the importance of inequality reduction in ending poverty and boosting shared prosperity by 2030 in a context of weaker growth. Third, it will highlight the diversity of within-country inequality reduction experiences and will synthesize experiences of successful countries and policies, addressing the roots of inequality without compromising economic growth. In doing so, the report will shatter some myths and sharpen our knowledge of what works in reducing inequalities. Finally, it will also advocate for the need to expand and improve data collection—for example, data availability, comparability, and quality—and rigorous evidence on inequality impacts in order to deliver high-quality poverty and shared prosperity monitoring.

Is there a tradeoff between raising growth and reducing inequality and poverty? This paper reviews the theoretical and empirical literature on the complex links between growth, inequality, and poverty, with causation going in both directions. The evidence suggests that growth can be effective in reducing poverty, but its impact on inequality is ambiguous and depends on the underlying sources of growth. The impact of poverty and inequality on growth is likewise ambiguous, as several channels mediate the relationship. But most plausible mechanisms suggest that poverty and inequality reduce growth, at least in the long run. Policies play a role in shaping these relationships and those designed to improve equality of opportunity can simultaneously improve inclusiveness and growth.
