This textbooks provides a comprehensive examination of poverty, wealth, and economic inequality from a psychological perspective.

Economic inequality is a defining issue of our time, with a handful of individuals in the United States today owning more wealth than half the population in the country. What are the psychological consequences of living in a profoundly unequal society? This comprehensive textbook is among the first to examine poverty, wealth, and economic inequality from a psychological perspective. Written by two leading scholars in the field, it provides an intersectional analysis of the impact of economic inequality on cognitive, emotional, interpersonal, intergroup, physiological, and health outcomes. Students are introduced to the diverse methods used to study poverty, wealth, and economic inequality and the strengths and weaknesses of various approaches, while the text focuses on solutions at the individual, community, and national levels to restore optimism and encourage action. Chapter features include exercises and reflection questions that help students think critically about the implications of research findings for their own lives.

Economic inequality has been of considerable interest to academics, citizens, and politicians worldwide for the past decade–and while economic inequality has attracted a considerable amount of research attention, it is only more recently that researchers have considered that economic inequality may have broader societal implications. However, while there is an increasingly clear picture of the varied ways in which economic inequality harms the fabric of society, there is a relatively poor understanding of the social psychological processes that are at work in unequal societies. This edited book aims to build on this emerging area of research by bringing together researchers who are at the forefront of this development and who can therefore provide timely insight to academics and practitioners who are grappling with the impact of economic inequality. This book will address questions relating to perceptions of inequality, mechanisms underlying effects of inequality, various consequences of inequality and the factors that contribute to the maintenance of inequality. The target audiences are students at advanced undergraduate or graduate level, as well as scholars and professionals in the field. The book fills a niche of both applied and practical relevance, strongly emphasizing theory and integration of different perspectives in social psychology. Given the broad interest in inequality within the social sciences, the book will be accessible to sociologists and political scientists as well as social, organizational, and developmental psychologists. The insights brought together in The Social Psychology of Inequality will contribute to a broader understanding of the far-reaching costs of inequality for the social health of a society and its citizens. "This edited volume brings together cutting-edge social psychological research addressing one of the most pressing issues of our times – economic inequality. Collectively, the chapters illuminate why inequality has negative effects on individuals and societies, when and for whom these negative effects are most likely to emerge, and the psychological mechanisms that maintain inequality. This comprehensive volume is an essential read for those interested in understanding and ameliorating inequality." -Brenda Major, Distinguished Professor, Department of Psychological and Brain Sciences, University of California “This invaluable volume demonstrates the indispensable and powerful contribution that social psychologists can make to our understanding of societal inequality. For those outside of social psychology it provides a unique and comprehensive overview of what social psychology has to offer, and for social psychologists it is exemplary in demonstrating how to make a systematic contribution to the understanding of a hotly debated real-world issue. Scholars and students alike and from various disciplines will gain much from reading this fascinating and inspiring social psychological journey.” -Maykel Verkuyten, Professor in Interdisciplinary Social Science, University of Utrecht “The Social Psychology of Inequality offers a superb and timely social-psychological analysis of the causes and consequence of increasing wealth and income gaps. With its refreshingly international authorship, this volume offers profound insights into the cognitive and social mechanisms that help maintain, but potentially also to overcome, an economy that is rigged in favor of the wealthy. A new and stimulating voice, illustrating science in the service of a fairer and more democratic society.” -Anne Maass, Professor of Social Psychology, University of Padova “This volume assembles an impressive list of leading international scholars to address a timely and important issue, the causes and consequences of economic inequality. The approach to the topic is social psychological, but the editors and chapters make valuable connections to related literatures on socio-structural influences in allied disciplines, such as economics, political science, and sociology. The Social Psychology of Inequality offers cutting-edge insights into the psychological dynamics of inequality and novel synthesis of structural- and individual-level influences and outcomes of inequality. It should attract a wide audience and will set the agenda for research on economic inequality well into the future.” -John F. Dovidio, Carl Iver Hovland Professor of Psychology and Public Health, Yale University

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.

"A persuasive and highly readable account." —President Barack Obama “Brilliant. . . . an important, fascinating read arguing that inequality creates a public health crisis in America.” —Nicholas Kristof, New York Times “The Broken Ladder is an important, timely, and beautifully written account of how inequality affects us all.” —Adam Alter, New York Times bestselling author of Irresistible and Drunk Tank Pink A timely examination by a leading scientist of the physical, psychological, and moral effects of inequality. The levels of inequality in the world today are on a scale that have not been seen in our lifetimes, yet the disparity between rich and poor has ramifications that extend far beyond mere financial means. In The Broken Ladder psychologist Keith Payne examines how inequality divides us not just economically; it also has profound consequences for how we think, how we respond to stress, how our immune systems function, and even how we view moral concepts such as justice and fairness. Research in psychology, neuroscience, and behavioral economics has not only revealed important new insights into how inequality changes people in predictable ways but also provided a corrective to the flawed view of poverty as being the result of individual character failings. Among modern developed societies, inequality is not primarily a matter of the actual amount of money people have. It is, rather, people's sense of where they stand in relation to others. Feeling poor matters—not just being poor. Regardless of their average incomes, countries or states with greater levels of income inequality have much higher rates of all the social maladies we associate with poverty, including lower than average life expectancies, serious health problems, mental illness, and crime. The Broken Ladder explores such issues as why women in poor societies often have more children, and why they have them at a younger age; why there is little trust among the working class in the prudence of investing for the future; why people's perception of their social status affects their political beliefs and leads to greater political divisions; how poverty raises stress levels as effectively as actual physical threats; how inequality in the workplace affects performance; and why unequal societies tend to become more religious. Understanding how inequality shapes our world can help us better understand what drives ideological divides, why high inequality makes the middle class feel left behind, and how to disconnect from the endless treadmill of social comparison.

What circumstances or behaviors turn poverty into a cycle that perpetuates across generations? The answer to this question carries especially important implications for the design and evaluation of policies and projects intended to reduce poverty. Yet a major challenge analysts and policymakers face in understanding poverty traps is the sheer number of mechanisms—not just financial, but also environmental, physical, and psychological—that may contribute to the persistence of poverty all over the world. The research in this volume explores the hypothesis that poverty is self-reinforcing because the equilibrium behaviors of the poor perpetuate low standards of living. Contributions explore the dynamic, complex processes by which households accumulate assets and increase their productivity and earnings potential, as well as the conditions under which some individuals, groups, and economies struggle to escape poverty. Investigating the full range of phenomena that combine to generate poverty traps—gleaned from behavioral, health, and resource economics as well as the sociology, psychology, and environmental literatures—chapters in this volume also present new evidence that highlights both the insights and the limits of a poverty trap lens. The framework introduced in this volume provides a robust platform for studying well-being dynamics in developing economies.

This volume is constituted of a collection of leading contributions, each focusing on understanding the global dynamics of poverty and wealth together, from a psychological (particularly social psychological) perspective. It is one of few (if any) books on the subject that combines psychological theory and research with community development and practice.
