Tax Progressivity And Income Inequality

This book assembles nine papers on tax progressivity and its relationship to income inequality, written by leading public finance economists. The papers document the changes during the 1980s in progressivity at the federal, state, and local level in the US. One chapter investigates the extent to which the declining progressivity contributed to the well-documented increase in income inequality over the past two decades, while others investigate the economic impact and cost of progressive tax systems. Special attention is given to the behavioral response to taxation of high-income individuals, portfolio behavior, and the taxation of capital gains. The concluding set of essays addresses the contentious issue of what constitutes a 'fair' tax system, contrasting public attitudes towards alternative tax systems to economists' notions of fairness. Each essay is followed by remarks of a commentator plus a summary of the discussion among contributors.

This paper discusses how the structure of the tax system affects its progressivity. It suggests a measure of progressive capacity of tax systems, based on the Kakwani index, but independent of pre-tax income distributions. Using this and other progressivity measures, the paper (i) documents a decline in progressivity over the last decades and (ii) examines the relationship between progressivity and economic growth. Regressions do not reveal a significant impact of progressivity on growth, suggesting that efficiency costs of progressivity may be small—at least for degrees of progressivity observed in the sample.

This paper explores the revenue-raising aspect of progressive taxation and derives, on the basis of a simple model, the optimal degree of tax progressivity where the tax revenue is used exclusively to finance (perfectly) targeted transfers to the poor. The paper shows that not only would it be optimal to finance the targeted transfers with progressive taxation, but that the optimal progressivity increases unambiguously with growing income inequality. This conclusion holds up under different assumptions about the efficiency cost of taxation and society’s aversion to inequality.

America’s runaway inequality has an engine: our unjust tax system. Even as they became fabulously wealthy, the ultra-rich have had their taxes collapse to levels last seen in the 1920s. Meanwhile, working-class Americans have been asked to pay more. The Triumph of Injustice presents a forensic investigation into this dramatic transformation, written by two economists who revolutionized the study of inequality. Eschewing anecdotes and case studies, Emmanuel Saez and Gabriel Zucman offer a comprehensive view of America’s tax system, based on new statistics covering all taxes paid at all levels of government. Their conclusion? For the first time in more than a century, billionaires now pay lower tax rates than their secretaries. Blending history and cutting-edge economic analysis, and writing in lively and jargon-free prose, Saez and Zucman dissect the deliberate choices (and sins of indecision) that have brought us to today: the gradual exemption of capital owners; the surge of a new tax avoidance industry, and the spiral of tax competition among nations. With clarity and concision, they explain how America turned away from the most progressive tax system in history to embrace policies that only serve to compound the wealth of a few. But The Triumph of Injustice is much more than a laser-sharp analysis of one of the great political and intellectual failures of our time. Saez and Zucman propose a visionary, democratic, and practical reinvention of taxes, outlining reforms that can allow tax justice to triumph in today’s globalized world and democracy to prevail over concentrated wealth. A pioneering companion website allows anyone to evaluate proposals made by the authors, and to develop their own alternative tax reform at taxjusticenow.org.

Research on Economic Inequality, volume 26, primarily contains papers presented at the 8th Society for the Study of Economic Inequality (ECINEQ) meeting. The papers cover such topics as the effect of inheritance taxation on the "pre-distribution" of income, and tax progressivity under alternative inequality definitions.

This paper explores the links between two phenomena of the past two decades: striking increase in the inequality of pre-tax incomes, and the failure of tax-and-transfer progressivity to increase. We emphasize the causal links going from inequality to progressivity, noting that optimal taxation theory predicts that growing inequality should increase progressivity. We discuss public choice alternatives to the optimal progressivity framework. The paper also addresses the opposite causal direction: that it is changes in taxation that have caused an apparent increase in inequality. Finally, we discuss the non-event-study' offered by the large changes in the distribution of income--with no major tax changes-- since 1995, and discuss its implications for the link between progressivity and inequality.

"Rising income inequality has been at the forefront of public debate in Canada in recent years, yet there is still much to be learned about the economic forces driving the distribution of earnings and income in this country and how they might evolve in coming years. With research showing that the tax-and-transfer system is less effective than in the past in counteracting growing income disparities, the need for policy-makers to understand the factors at play is all the more urgent. The Institute for Research on Public Policy, in collaboration with the Canadian Labour Market and Skills Researcher Network, has gathered some of the country’s leading experts to provide new evidence on the causes and effects of rising income inequality in Canada and to consider the role of policy. Their research and analysis constitutes a comprehensive review of Canadian inequality trends in recent decades, including changing earnings and income dynamics among middle--class and top earners, wage and job polarization across provinces, and persistent poverty among vulnerable groups. The authors also examine the changing role of education and unionization, as well as the complex interplay of redistributive policies and politics, in order to propose new directions for policy. Amid growing anxieties about the economic prospects of the middle class, Income Inequality: The Canadian Story will inform the public discourse on this issue of central concern for all Canadians."--Publisher's website.
