To what extent are major social and political problems caused by basic income and unemployment trends? Is it possible to restore the kind of broadly shared prosperity the U.S. once experienced before the early 1970s? Some of the top economists of our time address these critical questions.

Poverty and Shared Prosperity 2016 is the first of an annual flagship report that will inform a global audience comprising development practitioners, policy makers, researchers, advocates, and citizens in general with the latest and most accurate estimates on trends in global poverty and shared prosperity. This edition will also document trends in inequality and identify recent country experiences that have been successful in reducing inequalities, provide key lessons from those experiences, and synthesize the rigorous evidence on public policies that can shift inequality in a way that bolsters poverty reduction and shared prosperity in a sustainable manner. Specifically, the report will address the following questions: • What is the latest evidence on the levels and evolution of extreme poverty and shared prosperity? • Which countries and regions have been more successful in terms of progress toward the twin goals and which are lagging behind? • What does the global context of lower economic growth mean for achieving the twin goals? • How can inequality reduction contribute to achieving the twin goals? • What does the evidence show concerning global and between- and within-country inequality trends? • Which interventions and countries have used the most innovative approaches to achieving the twin goals through reductions in inequality? The report will make four main contributions. First, it will present the most recent numbers on poverty, shared prosperity, and inequality. Second, it will stress the importance of inequality reduction in ending poverty and boosting shared prosperity by 2030 in a context of weaker growth. Third, it will highlight the diversity of within-country inequality reduction experiences and will synthesize experiences of successful countries and policies, addressing the roots of inequality without compromising economic growth. In doing so, the report will shatter some myths and sharpen our knowledge of what works in reducing inequalities. Finally, it will also advocate for the need to expand and improve data collection—for example, data availability, comparability, and quality—and rigorous evidence on inequality impacts in order to deliver high-quality poverty and shared prosperity monitoring.

This edition of the biennial Poverty and Shared Prosperity report brings sobering news. The COVID-19 (coronavirus) pandemic and its associated economic crisis, compounded by the effects of armed conflict and climate change, are reversing hard-won gains in poverty reduction and shared prosperity. The fight to end poverty has suffered its worst setback in decades after more than 20 years of progress. The goal of ending extreme poverty by 2030, already at risk before the pandemic, is now beyond reach in the absence of swift, significant, and sustained action, and the objective of advancing shared prosperity—raising the incomes of the poorest 40 percent in each country—will be much more difficult. Poverty and Shared Prosperity 2020: Reversals of Fortune presents new estimates of COVID-19's impacts on global poverty and shared prosperity. Harnessing fresh data from frontline surveys and economic simulations, it shows that pandemic-related job losses and deprivation worldwide are hitting already poor and vulnerable people hard, while also shifting the profile of global poverty to include millions of 'new poor.' Original analysis included in the report shows that the new poor are more urban, better educated, and less likely to work in agriculture than those living in extreme poverty before COVID-19. It also gives new estimates of the impact of conflict and climate change, and how they overlap. These results are important for targeting policies to safeguard lives and livelihoods. It shows how some countries are acting to reverse the crisis, protect those most vulnerable, and promote a resilient recovery. These findings call for urgent action. If the global response fails the world's poorest and most vulnerable people now, the losses they have experienced to date will be minimal compared with what lies ahead. Success over the long term will require much more than stopping COVID-19. As efforts to curb the disease and its economic fallout intensify, the interrupted development agenda in low- and middle-income countries must be put back on track. Recovering from today's reversals of fortune requires tackling the economic crisis unleashed by COVID-19 with a commitment proportional to the crisis itself. In doing so, countries can also plant the seeds for dealing with the long-term development challenges of promoting inclusive growth, capital accumulation, and risk prevention—particularly the risks of conflict and climate change.

The World Bank Group has two overarching goals: End extreme poverty by 2030 and promote shared prosperity by boosting the incomes of the bottom 40 percent of the population in each economy. As this year’s Poverty and Shared Prosperity report documents, the world continues to make progress toward these goals. In 2015, approximately one-tenth of the world’s population lived in extreme poverty, and the incomes of the bottom 40 percent rose in 77 percent of economies studied. But success cannot be taken for granted. Poverty remains high in Sub- Saharan Africa, as well as in fragile and conflict-affected states. At the same time, most of the world’s poor now live in middle-income countries, which tend to have higher national poverty lines. This year’s report tracks poverty comparisons at two higher poverty thresholds—$3.20 and $5.50 per day—which are typical of standards in lower- and upper-middle-income countries. In addition, the report introduces a societal poverty line based on each economy’s median income or consumption. Poverty and Shared Prosperity 2018: Piecing Together the Poverty Puzzle also recognizes that poverty is not only about income and consumption—and it introduces a multidimensional poverty measure that adds other factors, such as access to education, electricity, drinking water, and sanitation. It also explores how inequality within households could affect the global profile of the poor. All these additional pieces enrich our understanding of the poverty puzzle, bringing us closer to solving it. For more information, please visit worldbank.org/PSP

A book that rewrites the history of American prosperity and inequality Unequal Gains offers a radically new understanding of the economic evolution of the United States, providing a complete picture of the uneven progress of America from colonial times to today. While other economic historians base their accounts on American wealth, Peter Lindert and Jeffrey Williamson focus instead on income—and the result is a bold reassessment of the American economic experience. America has been exceptional in its rising inequality after an egalitarian start, but not in its long-run growth. America had already achieved world income leadership by 1700, not just in the twentieth century as is commonly thought. Long before independence, American colonists enjoyed higher living standards than Britain—and America's income advantage today is no greater than it was three hundred years ago. But that advantage was lost during the Revolution, lost again during the Civil War, and lost a third time during the Great Depression, though it was regained after each crisis. In addition, Lindert and Williamson show how income inequality among Americans rose steeply in two great waves—from 1774 to 1860 and from the 1970s to today—rising more than in any other wealthy nation in the world. Unequal Gains also demonstrates how the widening income gaps have always touched every social group, from the richest to the poorest. The book sheds critical light on the forces that shaped American income history, and situates that history in a broad global context. Economic writing at its most stimulating, Unequal Gains provides a vitally needed perspective on who has benefited most from American growth, and why.

“Rolf shows that raising the minimum wage to $15 is both just and necessary, lest the American dream of middle class prosperity turn into a nightmare” (David Cay Johnston, Pulitzer Prize–winning journalist). Combining history, economics, and commonsense political wisdom, The Fight for $15 makes a deeply informed case for a national fifteen-dollars-an-hour minimum wage as the only practical solution to reversing America’s decades-long slide toward becoming a low-wage nation. Drawing both on new scholarship and on his extensive practical experiences organizing workers and grappling with inequality across the United States, David Rolf, president of SEIU 775—which waged the successful Seattle campaign for a fifteen dollar minimum wage—offers an accessible explanation of “middle out” economics, an emerging popular economic theory that suggests that the origins of prosperity in capitalist economies lie with workers and consumers, not investors and employers. A blueprint for a different and hopeful American future, The Fight for $15 offers concrete tools, ideas, and inspiration for anyone interested in real change in our lifetimes. “The author’s plainspoken approach and stellar scholarship illuminate in-depth discussions about the deliberate policy decisions that began to decimate the middle class at the start of the 1980s as well as the insidious new ways in which big business continues to attack American workers today via stagnant wages, rampant subcontracting, unpredictable scheduling, and other detrimental practices associated with the so-called ‘share economy.’” —Kirkus Reviews “David Rolf has become the most successful advocate for raising wages in the twenty-first century.” —Andy Stern, senior fellow at Columbia University’s Richard Paul Richman Center for Business, Law, and Public Policy

We are living in a time of extreme inequality: America’s three richest people now own as much wealth as the bottom half of the population. Although most accept that this is grotesque, many politicians accept it as irreversible. In this book, leading US researcher and activist Chuck Collins succinctly diagnoses the drivers of rampant inequality, arguing that such disparities have their roots in 40 years of the powerful rigging the system in their favor. He proposes a far-reaching policy agenda, analyzes the barriers to progress, and shows how transformative local campaigns can become a national movement for change. This book is a powerful analysis of how the plutocracy sold us a toxic lie, and what we can do to reverse inequality.

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.
