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.

“One of the world’s most inspired and unusual poets . . . [Seidel’s] poems are a triumph of cosmic awe in the face of earthly terror.” —Hillel Italie, USA Today Frederick Seidel has been called many things. A “transgressive adventurer,” “a demonic gentleman,” a “triumphant outsider,” “a great poet of innocence,” and “an example of the dangerous Male of the Species,” just to name a few. Whatever you choose to call him, one thing is certain: “he radiates heat” (The New Yorker). Now add to that: the poet of aging and decrepitude. Widening Income Inequality, Seidel’s new poetry collection, is a rhymed magnificence of sexual, historical, and cultural exuberance, a sweet and bitter fever of Robespierre and Obamacare and Apollinaire, of John F. Kennedy and jihadi terror and New York City and Italian motorcycles. Rarely has poetry been this true, this dapper, or this dire. Seidel is “the most poetic of the poets and their leader into hell.”

This volume brings together an exciting range of new studies of top incomes in a wide range of countries from around the world. The studies use data from income tax records to cast light on the dramatic changes that have taken place at the top of the income distribution. The results cover 22 countries and have a long time span, going back to 1875.

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 posit that the relationship between income inequality and economic growth is mediated by the level of equality of opportunity, which we identify with intergenerational mobility. In economies characterized by intergenerational rigidities, an increase in income inequality has persistent effects—for example by hindering human capital accumulation— thereby retarding future growth disproportionately. We use several recently developed internationally comparable measures of intergenerational mobility to confirm that the negative impact of income inequality on growth is higher the lower is intergenerational mobility. Our results suggest that omitting intergenerational mobility leads to misspecification, shedding light on why the empirical literature on income inequality and growth has been so inconclusive.

From a leading authority on race and public policy, a deeply researched account of how families rise and fall today Since the Great Recession, most Americans' standard of living has stagnated or declined. Economic inequality is at historic highs. But inequality's impact differs by race; African Americans' net wealth is just a tenth that of white Americans, and over recent decades, white families have accumulated wealth at three times the rate of black families. In our increasingly diverse nation, sociologist Thomas M. Shapiro argues, wealth disparities must be understood in tandem with racial inequities -- a dangerous combination he terms "toxic inequality." In Toxic Inequality, Shapiro reveals how these forces combine to trap families in place. Following nearly two hundred families of different races and income levels over a period of twelve years, Shapiro's research vividly documents the recession's toll on parents and children, the ways families use assets to manage crises and create opportunities, and the real reasons some families build wealth while others struggle in poverty. The structure of our neighborhoods, workplaces, and tax code-much more than individual choices-push some forward and hold others back. A lack of assets, far more common in families of color, can often ruin parents' careful plans for themselves and their children. Toxic inequality may seem inexorable, but it is not inevitable. America's growing wealth gap and its yawning racial divide have been forged by history and preserved by policy, and only bold, race-conscious reforms can move us toward a more just society. "Everyone concerned about the toxic effects of inequality must read this book." -- Robert B. Reich "This is one of the most thought-provoking books I have read on economic inequality in the US." -- William Julius Wilson

Eight papers, both theoretical and applied, on the concept of equality of opportunity which says that a society should guarantee its members equal access to advantage regardless of their circumstances, while holding them responsible for turning that access into actual advantage by the application of effort.
