Inequality has drastically increased in many countries around the globe over the past three decades. The widening gap between the very rich and everyone else is often portrayed as an unexpected outcome or as the tradeoff we must accept to achieve economic growth. In this book, three International Monetary Fund economists show that this increase in inequality has in fact been a political choice—and explain what policies we should choose instead to achieve a more inclusive economy. Jonathan D. Ostry, Prakash Loungani, and Andrew Berg demonstrate that the extent of inequality depends on the policies governments choose—such as whether to let capital move unhindered across national boundaries, how much austerity to impose, and how much to deregulate markets. While these policies do often confer growth benefits, they have also been responsible for much of the increase in inequality. The book also shows that inequality leads to weaker economic performance and proposes alternative policies capable of delivering more inclusive growth. In addition to improving access to health care and quality education, they call for redistribution from the rich to the poor and present evidence showing that redistribution does not hurt growth. Accessible to scholars across disciplines as well as to students and policy makers, Confronting Inequality is a rigorous and empirically rich book that is crucial for a time when many fear a new Gilded Age.

A Financial Times Best Book of the Year A hardheaded book that confronts and outlines possible solutions to a seemingly intractable problem: that helping the poor often hurts the environment, and vice versa. Can we fight poverty and inequality while protecting the environment? The challenges are obvious. To rise out of poverty is to consume more resources, almost by definition. And many measures to combat pollution lead to job losses and higher prices that mainly hurt the poor. In Unsustainable Inequalities, economist Lucas Chancel confronts these difficulties head-on, arguing that the goals of social justice and a greener world can be compatible, but that progress requires substantial changes in public policy. Chancel begins by reviewing the problems. Human actions have put the natural world under unprecedented pressure. The poor are least to blame but suffer the most—forced to live with pollutants that the polluters themselves pay to avoid. But Chancel shows that policy pioneers worldwide are charting a way forward. Building on their success, governments and other large-scale organizations must start by doing much more simply to measure and map environmental inequalities. We need to break down the walls between traditional social policy and environmental protection—making sure, for example, that the poor benefit most from carbon taxes. And we need much better coordination between the center, where policies are set, and local authorities on the front lines of deprivation and contamination. A rare work that combines the quantitative skills of an economist with the argumentative rigor of a philosopher, Unsustainable Inequalities shows that there is still hope for solving even seemingly intractable social problems.

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.

The Fund has recognized in recent years that one cannot separate issues of economic growth and stability on one hand and equality on the other. Indeed, there is a strong case for considering inequality and an inability to sustain economic growth as two sides of the same coin. Central to the Fund’s mandate is providing advice that will enable members’ economies to grow on a sustained basis. But the Fund has rightly been cautious about recommending the use of redistributive policies given that such policies may themselves undercut economic efficiency and the prospects for sustained growth (the so-called “leaky bucket” hypothesis written about by the famous Yale economist Arthur Okun in the 1970s). This SDN follows up the previous SDN on inequality and growth by focusing on the role of redistribution. It finds that, from the perspective of the best available macroeconomic data, there is not a lot of evidence that redistribution has in fact undercut economic growth (except in extreme cases). One should be careful not to assume therefore—as Okun and others have—that there is a big tradeoff between redistribution and growth. The best available macroeconomic data do not support such a conclusion.

Originally published in 1975, Equality and Efficiency: The Big Tradeoff is a very personal work from one of the most important macroeconomists of the last hundred years. And this new edition includes "Further Thoughts on Equality and Efficiency," a paper published by the author two years later. In classrooms Arthur M. Okun may be best remembered for Okun's Law, but his lasting legacy is the respect and admiration he earned from economists, practitioners, and policymakers. Equality and Efficiency is the perfect embodiment of that legacy, valued both by professional economists and those readers with a keen interest in social policy. To his fellow economists, Okun presents messages, in the form of additional comments and select citations, in his footnotes. To all readers, Okun presents an engaging dual theme: the market needs a place, and the market needs to be kept in its place. As Okun puts it: Institutions in a capitalist democracy prod us to get ahead of our neighbors economically after telling us to stay in line socially. This double standard professes and pursues an egalitarian political and social system while simultaneously generating gaping disparities in economic well-being. Today, Okun's dual theme feels incredibly prescient as we grapple with the hot-button topic of income inequality. In his foreword, Lawrence H. Summers declares: On what one might think of as questions of "economic philosophy," I doubt that Okun has been improved on in the subsequent interval. His discussion of how societies rely on rights as well as markets should be required reading for all young economists who are enamored with market solutions to all problems.

Essays exploring the relationship between economic growth and inequality and the implications for policy makers.

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.
