Global Income Inequality

"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.

The surprising finding of this book is that, contrary to conventional wisdom, global income inequality is decreasing. Critics of globalization and others maintain that the spread of consumer capitalism is dramatically polarizing the worldwide distribution of income. But as the demographer Glenn Firebaugh carefully shows, income inequality for the world peaked in the late twentieth century and is now heading downward because of declining income inequality across nations. Furthermore, as income inequality declines across nations, it is rising within nations (though not as rapidly as it is declining across nations). Firebaugh claims that this historic transition represents a new geography of global income inequality in the twenty-first century. This book documents the new geography, describes its causes, and explains why other analysts have missed one of the defining features of our era--a transition in inequality that is reducing the importance of where a person is born in determining his or her future well-being.

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.

A rapidly growing area of economic research investigates the top of the income distribution using data from income tax records. This volume brings together studies of top incomes for twelve countries from around the world, including China, India, Japan, Argentina and Indonesia. Together with the first volume, published in 2007, the studies cover twenty two countries. They have a long time span, the earliest data relating to 1875 (for Norway), allowing recent developments to be placed in historical perspective. The volume describes in detail the source data and the methods employed. It will be an invaluable reference source for researchers in the field. Individual country chapters deal with the specific nature of the data for each of the countries, and describe the long-term evolution of top income shares. In the countries as a whole, dramatic changes have taken place at the top of the income distribution. Over the first part of the century, top income shares fell markedly. This largely took the form of a reduction in capital incomes. The different authors examine the impact of the First and Second World Wars, contrasting countries that were and were not engaged. They consider the impact of depressions and banking crises, and pay particular attention to the impact of progressive taxation. In the last 30 years, the shares of top incomes have increased markedly in the US and other Anglo-Saxon countries, reflecting the increased dispersion of earnings. The volume includes statistics on the much-discussed top pay and bonuses, providing a global perspective that discusses important differences between countries such as the lesser increase in Continental Europe. This book, together with volume 1, documents this interesting development and explores the underlying causes. The findings are brought together in a final summary chapter by Atkinson, Piketty and Saez.

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.

Inequality has emerged as a key development challenge. It holds implications for economic growth and redistribution and translates into power asymmetries that can endanger human rights, create conflict, and embed social exclusion and chronic poverty. For these reasons, it underpins intense public and academic debates and has become a dominant policy concern within many countries and in all multilateral agencies. It is at the core of the 17 goals of the UN 2030 Agenda for Sustainable Development. This book contributes to this important discussion by presenting assessments of the measurement and analysis of global inequality by leading inequality scholars, aligning these to comprehensive reviews of inequality trends in five of the world's largest developing countries - Brazil, China, India, Mexico, and South Africa.

Income inequality is rising. A quarter of a century ago, the average disposable income of the richest 10% in OECD countries was around seven times higher than that of the poorest 10%; today, it's around 9½ times higher. Why does this matter? Many fear this widening gap is hurting individuals, societies and even economies. This book explores income inequality across five main headings. It starts by explaining some key terms in the inequality debate. It then examines recent trends and explains why income inequality varies between countries. Next it looks at why income gaps are growing and, in particular, at the rise of the 1%. It then looks at the consequences, including research that suggests widening inequality could hurt economic growth. Finally, it examines policies for addressing inequality and making economies more inclusive.

Winner of the Bruno Kreisky Prize, Karl Renner Institut A Financial Times Best Economics Book of the Year An Economist Best Book of the Year A Livemint Best Book of the Year One of the world’s leading economists of inequality, Branko Milanovic presents a bold new account of the dynamics that drive inequality on a global scale. Drawing on vast data sets and cutting-edge research, he explains the benign and malign forces that make inequality rise and fall within and among nations. He also reveals who has been helped the most by globalization, who has been held back, and what policies might tilt the balance toward economic justice. “The data [Milanovic] provides offer a clearer picture of great economic puzzles, and his bold theorizing chips away at tired economic orthodoxies.” —The Economist “Milanovic has written an outstanding book...Informative, wide-ranging, scholarly, imaginative and commendably brief. As you would expect from one of the world’s leading experts on this topic, Milanovic has added significantly to important recent works by Thomas Piketty, Anthony Atkinson and François Bourguignon...Ever-rising inequality looks a highly unlikely combination with any genuine democracy. It is to the credit of Milanovic’s book that it brings out these dangers so clearly, along with the important global successes of the past few decades. —Martin Wolf, Financial Times
