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.
This report provides evidence of a fairly generalised increase in income inequality over the past two decades across OECD countries, but the timing, intensity and causes of the increase differ from what is typically suggested in the media.
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.
This state-of-the-art volume presents comparative, empirical research on a topic that has long preoccupied scholars, politicians, and everyday citizens: economic inequality. While income and wealth inequality across all populations is the primary focus, the contributions to this book pay special attention to the middle class, a segment often not addressed in inequality literature. Written by leading scholars in the field of economic inequality, all 17 chapters draw on microdata from the databases of LIS, an esteemed cross-national data center based in Luxembourg. Using LIS data to structure a comparative approach, the contributors paint a complex portrait of inequality across affluent countries at the beginning of the 21st century. The volume also trail-blazes new research into inequality in countries newly entering the LIS databases, including Japan, Iceland, India, and South Africa.
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.
It is not necessarily true that such income transfers would invariably reduce growth rates. The relationship between economic growth and income inequality depends on certain initial conditions. For instance, if the initial distribution of income is fairly unequal, growth induces greater equality. On the other hand, at high levels of per capita incomes, growth may raise inequality if the initial level of inequality is not very high. This brings a new dimension in the "inverted-U hypothesis." Based on econometric modeling of growth-inequality nexus, the book examines the patterns of growth and economic disparities in BRIC countries over long periods of time, including the recent high growth phase. Two inequality measures applied in this study are Gini coefficient and Theil's entropy measures, depending on data availability. Attempts have been made to identify the sources of inequality and the role of initial conditions in determining the patterns of development.
The first fifteen years of the 21st century have thrown into sharp relief the challenges of growth, equity, stability, and sustainability facing the world economy. In addition, they have exposed the inadequacies of mainstream economics in providing answers to these challenges. This volume gathers over 50 leading scholars from around the world to offer a forward-looking perspective of economic geography to understanding the various building blocks, relationships, and trajectories in the world economy. The perspective is at the same time grounded in theory and in the experiences of particular places. Reviewing state-of-the-art of economic geography, setting agendas, and with illustrations and empirical evidence from all over the world, the book should be an essential reference for students, researchers, as well as strategists and policy makers. Building on the success of the first edition, this volume offers a radically revised, updated, and broader approach to economic geography. With the backdrop of the global financial crisis, finance is investigated in chapters on financial stability, financial innovation, global financial networks, the global map of savings and investments, and financialization. Environmental challenges are addressed in chapters on resource economies, vulnerability of regions to climate change, carbon markets, and energy transitions. Distribution and consumption feature alongside more established topics on the firm, innovation, and work. The handbook also captures the theoretical and conceptual innovations of the last fifteen years, including evolutionary economic geography and the global production networks approach. Addressing the dangers of inequality, instability, and environmental crisis head-on, the volume concludes with strategies for growth and new ways of envisioning the spatiality of economy for the future.
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.
What is income inequality? How is it measured? Is the middle class really declining? How does it relate to poverty? How long has inequality been rising in the US? Have there been other periods in history when income differences were as large as they are today? What are the causes of growing income and wage inequality? The author addresses these and other conceptual issues in eight carefully reasoned and clearly presented chapters. Concluding with an analysis and comparison of trends in wage inequality in other developed countries, he asks the final speculative question: How much more growth in inequality can our society withstand?
The sizeable increase in income inequality experienced in advanced economies and many parts of the world since the 1990s and the severe consequences of the global economic and financial crisis have brought distributional issues to the top of the policy agenda. The challenge for many governments is to address concerns over rising inequality while simultaneously promoting economic efficiency and more robust economic growth. The book delves into this discussion by analyzing fiscal policy and its link with inequality. Fiscal policy is the government’s most powerful tool for addressing inequality. It affects households ‘consumption directly (through taxes and transfers) and indirectly (via incentives for work and production and the provision of public goods and individual services such as education and health). An important message of the book is that growth and equity are not necessarily at odds; with the appropriate mix of policy instruments and careful policy design, countries can in many cases achieve better distributional outcomes and improve economic efficiency. Country studies (on the Netherlands, China, India, Republic of Congo, and Brazil) demonstrate the diversity of challenges across countries and their differing capacity to use fiscal policy for redistribution. The analysis presented in the book builds on and extends work done at the IMF, and also includes contributions from leading academics.
