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.
We provide a systematic analysis of the properties of individual returns to wealth using twelve years of population data from Norway’s administrative tax records. We document a number of novel results. First, during our sample period individuals earn markedly different average returns on their financial assets (a standard deviation of 14%) and on their net worth (a standard deviation of 8%). Second, heterogeneity in returns does not arise merely from differences in the allocation of wealth between safe and risky assets: returns are heterogeneous even within asset classes. Third, returns are positively correlated with wealth: moving from the 10th to the 90th percentile of the financial wealth distribution increases the return by 3 percentage points - and by 17 percentage points when the same exercise is performed for the return to net worth. Fourth, wealth returns exhibit substantial persistence over time. We argue that while this persistence partly reflects stable differences in risk exposure and assets scale, it also reflects persistent heterogeneity in sophistication and financial information, as well as entrepreneurial talent. Finally, wealth returns are (mildly) correlated across generations. We discuss the implications of these findings for several strands of the wealth inequality debate.
A Nobel Prize–winning economist tells the remarkable story of how the world has grown healthier, wealthier, but also more unequal over the past two and half centuries The world is a better place than it used to be. People are healthier, wealthier, and live longer. Yet the escapes from destitution by so many has left gaping inequalities between people and nations. In The Great Escape, Nobel Prize–winning economist Angus Deaton—one of the foremost experts on economic development and on poverty—tells the remarkable story of how, beginning 250 years ago, some parts of the world experienced sustained progress, opening up gaps and setting the stage for today's disproportionately unequal world. Deaton takes an in-depth look at the historical and ongoing patterns behind the health and wealth of nations, and addresses what needs to be done to help those left behind. Deaton describes vast innovations and wrenching setbacks: the successes of antibiotics, pest control, vaccinations, and clean water on the one hand, and disastrous famines and the HIV/AIDS epidemic on the other. He examines the United States, a nation that has prospered but is today experiencing slower growth and increasing inequality. He also considers how economic growth in India and China has improved the lives of more than a billion people. Deaton argues that international aid has been ineffective and even harmful. He suggests alternative efforts—including reforming incentives to drug companies and lifting trade restrictions—that will allow the developing world to bring about its own Great Escape. Demonstrating how changes in health and living standards have transformed our lives, The Great Escape is a powerful guide to addressing the well-being of all nations.
Reflections on politics, the economy, and the modern world by the #1 New York Times–bestselling author of Capital in the Twenty-First Century. Thomas Piketty’s work has proved that unfettered markets lead to increasing inequality, and that without meaningful regulation, capitalist economies will concentrate wealth in an ever smaller number of hands, threatening democracy. For years, his newspaper columns have pierced the surface of current events to reveal the economic forces underneath. Why Save the Bankers? collects these columns from the period between the September 2008 collapse of Lehman Brothers and the November 2015 terrorist attacks in Paris. In crystalline prose, Piketty examines a wide range of topics, and along the way he decodes the European Union’s economic troubles, weighs in on oligarchy in the United States, wonders whether debts actually need to be paid back, and discovers surprising lessons about inequality by examining the career of Steve Jobs. Coursing with insight and flashes of wit, these brief essays offer a view of recent history through the eyes of one of the most influential economic thinkers of our time. “Easy to follow for readers without much knowledge of economics, especially when [Piketty] picks apart topics that defy classical economic logic; in this he resembles Paul Krugman, who similarly writes clearly on complex topics . . . Helps make sense of recent financial history.” —Kirkus Reviews “Anyone with an interest in politics, monetary policy, or international diplomacy will get a kick out of Piketty’s clear discussion.” —Shelf Awareness “If you have been influenced by Piketty’s landmark work on inequality, make sure to read this next.” —Naomi Klein, author of The Shock Doctrine and This Changes Everything
From New York Times bestselling author and economics columnist Robert Frank, a compelling book that explains why the rich underestimate the importance of luck in their success, why that hurts everyone, and what we can do about it How important is luck in economic success? No question more reliably divides conservatives from liberals. As conservatives correctly observe, people who amass great fortunes are almost always talented and hardworking. But liberals are also correct to note that countless others have those same qualities yet never earn much. In recent years, social scientists have discovered that chance plays a much larger role in important life outcomes than most people imagine. In Success and Luck, bestselling author and New York Times economics columnist Robert Frank explores the surprising implications of those findings to show why the rich underestimate the importance of luck in success—and why that hurts everyone, even the wealthy. Frank describes how, in a world increasingly dominated by winner-take-all markets, chance opportunities and trivial initial advantages often translate into much larger ones—and enormous income differences—over time; how false beliefs about luck persist, despite compelling evidence against them; and how myths about personal success and luck shape individual and political choices in harmful ways. But, Frank argues, we could decrease the inequality driven by sheer luck by adopting simple, unintrusive policies that would free up trillions of dollars each year—more than enough to fix our crumbling infrastructure, expand healthcare coverage, fight global warming, and reduce poverty, all without requiring painful sacrifices from anyone. If this sounds implausible, you'll be surprised to discover that the solution requires only a few, noncontroversial steps. Compellingly readable, Success and Luck shows how a more accurate understanding of the role of chance in life could lead to better, richer, and fairer economies and societies.
An innovative approach to measuring inequality providing the first full integration of distributional and macro level data for the US.
The authors conducted a systematic empirical study of cross-sectional inequality in the U.S., integrating data from various surveys. The authors follow the mapping suggested by the household budget constraint from individual wages to individual earnings, to household earnings, to disposable income, and, ultimately, to consumption and wealth. They document a continuous and sizable increase in wage inequality over the sample period. Changes in the distribution of hours worked sharpen the rise in earnings inequality before 1982, but mitigate its increase thereafter. Taxes and transfers compress the level of income inequality, especially at the bottom of the distribution, but have little effect on the overall trend. Charts and tables.

This collection of essays, coauthored with other distinguished economists, offers new perspectives on saving, intergenerational economic ties, retirement planning, and the distribution of wealth. The book links life-cycle microeconomic behavior to important macroeconomic outcomes, including the roughly 50 percent postwar decline in America's rate of saving and its increasing wealth inequality. The book traces these outcomes to the government's five-decade-long policy of transferring, in the form of annuities, ever larger sums from young savers to old spenders. The book presents new theoretical and empirical analyses of altruism that rule out the possibility that private intergenerational transfers have offset those by the government.While rational life-cycle behavior can explain broad economic outcomes, the book also shows that a significant minority of households fail to make coherent life-cycle saving and insurance decisions. These mistakes are compounded by reliance on conventional financial planning tools, which the book compares with Economic Security Planner (ESPlanner), a new life-cycle financial planning software program. The application of ESPlanner to U.S. data indicates that most Americans approaching retirement age are saving at much lower rates than they should be, given potential major cuts in Social Security benefits.
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.
