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.

This report revisits the theoretical concepts of inequalities including their measurements, analyzes their global trends, presents the policy makers' perception of inequalities in 15 countries and identifies various policy options in combating this major development challenge of our time. The report makes the basic point that in spite of the impressive progress humanity has made on many fronts over the decades, it still remains deeply divided. In that context, it is intended to help development actors, citizens, and policy makers contribute to global dialogues and initiate conversations in their own countries about the drivers and extent of inequalities, their impact, and the ways in which they can be curbed.

Inequalities of wealth and income have a significant impact for the achievement of economic, political and human development in developing counties. This book argues that a high level of economic inequality undermines a country's growth potential, retards the development of social capital, and encourages corruption.

Most of the world's people live in "developing" economies, as do most of the world's poor. The predominant means of economic development is economic growth. In this book Gary Fields asks to what extent and in what circumstances economic growth improves the material standard of living of a country's people. Most development economists agree that economic growth raises the incomes of people in all parts of the income distribution and lowers the poverty rate. At the same time, some groups lose out because of changes accompanying economic growth. Fields examines these beliefs, asking what variables should be measured to determine whether progress is being made and what policies and circumstances cause some countries to do better than others. He also shows how the same data can be interpreted to reach different, even conflicting, conclusions. Using both theoretical and empirical approaches, Fields defines and examines inequality, poverty, income mobility, and economic well-being. Finally, he considers various policies for broad-based growth. Copublished with the Russell Sage Foundation.

'In bringing together seven regional studies by economists from the Global Development Network, Natalia Dinello and Lyn Squire provide an insightful perspective on the relationships between globalization and equity. The topic is important, but too often has been oversimplified and viewed through western lenses. Complexity does not preclude strong conclusions, dubbed the Cairo Consensus here, but its analysis is helped by the mix of expertise and local knowledge embodied in this book.' - Richard Pomfret, University of Adelaide, Australia

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.

One side in the current debate about who benefits from growth has focused solely on average impacts on poverty and inequality, while the other side has focused on the diverse welfare impacts found beneath the averages. Both sides have a point.
