Studies of wage and income inequality among U.S. citizens over the past thirty years have engendered the common wisdom that the rich are getting richer and the poor are getting poorer. But is it really that simple? In Inequality in Living Standards since 1980 the authors contend that the evolution of income and wage inequalities offers only a partial picture of changes in prosperity in recent decades.

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.

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.

In the United States, some populations suffer from far greater disparities in health than others. Those disparities are caused not only by fundamental differences in health status across segments of the population, but also because of inequities in factors that impact health status, so-called determinants of health. Only part of an individual's health status depends on his or her behavior and choice; community-wide problems like poverty, unemployment, poor education, inadequate housing, poor public transportation, interpersonal violence, and decaying neighborhoods also contribute to health inequities, as well as the historic and ongoing interplay of structures, policies, and norms that shape lives. When these factors are not optimal in a community, it does not mean they are intractable: such inequities can be mitigated by social policies that can shape health in powerful ways. Communities in Action: Pathways to Health Equity seeks to delineate the causes of and the solutions to health inequities in the United States. This report focuses on what communities can do to promote health equity, what actions are needed by the many and varied stakeholders that are part of communities or support them, as well as the root causes and structural barriers that need to be overcome.

This open access book investigates the link between income inequality and socio-economic residential segregation in 24 large urban regions in Africa, Asia, Australia, Europe, North America, and South America. It offers a unique global overview of segregation trends based on case studies by local author teams. The book shows important global trends in segregation, and proposes a Global Segregation Thesis. Rising inequalities lead to rising levels of socio-economic segregation almost everywhere in the world. Levels of inequality and segregation are higher in cities in lower income countries, but the growth in inequality and segregation is faster in cities in high-income countries. This is causing convergence of segregation trends. Professionalisation of the workforce is leading to changing residential patterns. High-income workers are moving to city centres or to attractive coastal areas and gated communities, while poverty is increasingly suburbanising. As a result, the urban geography of inequality changes faster and is more pronounced than changes in segregation levels. Rising levels of inequality and segregation pose huge challenges for the future social sustainability of cities, as cities are no longer places of opportunities for all.

"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.

A book that rewrites the history of American prosperity and inequality Unequal Gains offers a radically new understanding of the economic evolution of the United States, providing a complete picture of the uneven progress of America from colonial times to today. While other economic historians base their accounts on American wealth, Peter Lindert and Jeffrey Williamson focus instead on income—and the result is a bold reassessment of the American economic experience. America has been exceptional in its rising inequality after an egalitarian start, but not in its long-run growth. America had already achieved world income leadership by 1700, not just in the twentieth century as is commonly thought. Long before independence, American colonists enjoyed higher living standards than Britain—and America's income advantage today is no greater than it was three hundred years ago. But that advantage was lost during the Revolution, lost again during the Civil War, and lost a third time during the Great Depression, though it was regained after each crisis. In addition, Lindert and Williamson show how income inequality among Americans rose steeply in two great waves—from 1774 to 1860 and from the 1970s to today—rising more than in any other wealthy nation in the world. Unequal Gains also demonstrates how the widening income gaps have always touched every social group, from the richest to the poorest. The book sheds critical light on the forces that shaped American income history, and situates that history in a broad global context. Economic writing at its most stimulating, Unequal Gains provides a vitally needed perspective on who has benefited most from American growth, and why.
