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 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.

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.

Essays exploring the relationship between economic growth and inequality and the implications for policy makers.

Designed to be accessible to noneconomists, it relegates technical details to appendixes."--BOOK JACKET.

The celebrated economist Zvi Griliches’s entire career can be viewed as an attempt to advance the cause of accuracy in economic measurement. His interest in the causes and consequences of technical progress led to his pathbreaking work on price hedonics, now the principal analytical technique available to account for changes in product quality. Hard-to-Measure Goods and Services, a collection of papers from an NBER conference held in Griliches’s honor, is a tribute to his many contributions to current economic thought. Here, leading scholars of economic measurement address issues in the areas of productivity, price hedonics, capital measurement, diffusion of new technologies, and output and price measurement in “hard-to-measure” sectors of the economy. Furthering Griliches’s vital work that changed the way economists think about the U.S. National Income and Product Accounts, this volume is essential for all those interested in the labor market, economic growth, production, and real output.

Originally published in 1975, Equality and Efficiency: The Big Tradeoff is a very personal work from one of the most important macroeconomists of the last hundred years. And this new edition includes "Further Thoughts on Equality and Efficiency," a paper published by the author two years later. In classrooms Arthur M. Okun may be best remembered for Okun's Law, but his lasting legacy is the respect and admiration he earned from economists, practitioners, and policymakers. Equality and Efficiency is the perfect embodiment of that legacy, valued both by professional economists and those readers with a keen interest in social policy. To his fellow economists, Okun presents messages, in the form of additional comments and select citations, in his footnotes. To all readers, Okun presents an engaging dual theme: the market needs a place, and the market needs to be kept in its place. As Okun puts it: Institutions in a capitalist democracy prod us to get ahead of our neighbors economically after telling us to stay in line socially. This double standard professes and pursues an egalitarian political and social system while simultaneously generating gaping disparities in economic well-being. Today, Okun's dual theme feels incredibly prescient as we grapple with the hot-button topic of income inequality. In his foreword, Lawrence H. Summers declares: On what one might think of as questions of "economic philosophy," I doubt that Okun has been improved on in the subsequent interval. His discussion of how societies rely on rights as well as markets should be required reading for all young economists who are enamored with market solutions to all problems.
