From Optimal Tax Theory To Tax Policy

The author examines the role of optimal tax analysis in informing and influencing tax policy design.

Tax systems raise large amounts of revenue for funding public sector's activities, and tax/transfer policy, together with public provision of education, health care, and social services, play a crucial role in treating the symptoms and the causes of poverty. The normative analysis is crucial for tax/transfer design because it makes it possible to assess separately how changes in the redistributive criterion of the government, and changes in the size of the behavioural responses to taxes and transfers, affect the optimal tax/transfer system. Optimal tax theory provides a way of thinking rigorously about these trade-offs. Written primarily for graduate students and researchers, this volume is intended as a textbook and research monograph, connecting optimal tax theory to tax policy. It comments on some policy recommendations of the Mirrlees Review, and builds on the authors work on public economics, optimal tax theory, behavioural public economics, and income inequality. The book explains in depth the Mirrlees model and presents various extensions of it. The first set of extensions considers changing the preferences for consumption and work: behavioural-economic modifications (such as positional externalities, prospect theory, paternalism, myopic behaviour and habit formation) but also heterogeneous work preferences (besides differences in earnings ability). The second set of modifications concerns the objective of the government. The book explains the differences in optimal redistributive tax systems when governments - instead of maximising social welfare - minimise poverty or maximise social welfare based on rank order or charitable conservatism social welfare functions. The third set of extensions considers extending the Mirrlees income tax framework to allow for differential commodity taxes, capital income taxation, public goods provision, public provision of private goods, and taxation commodities that generate externalities. The fourth set of extensions considers incorporating a number of important real-word extensions such as tagging of tax schedules to certain groups of tax payers. In all extensions, the book illustrates the main mechanisms using advanced numerical simulations.

A concise and rigorous text that combines theory, empirical work, and policy discussion to present core issues in the economics of taxation. This concise introduction to the economic theories of taxation is intuitive yet rigorous, relating the theories both to existing tax systems and to key empirical studies. The Economics of Taxation offers a thorough discussion of the consequences of taxes on economic decisions and equilibrium outcomes, as well as useful insights into how policy makers should design taxes. It covers such issues of central policy importance as taxation of income from capital, environmental taxation, and tax credits for low-income families. This second edition has been significantly revised and updated. Changes include a substantially rewritten chapter on direct taxation; a discussion of recent research in the chapter on mixed taxation; the replacement of the chapter on capital taxation with a chapter on the “new dynamic public finance”; and considerations of environmental taxation in both theory and policy chapters. The book is aimed at graduate students or advanced undergraduates taking public finance classes as well as economists who want to learn more about the topic. It combines discussion of theory, empirical work, and policy objectives in compact form. Appendixes provide necessary background material on consumer and producer theory and the theory of optimal control.

Tax policies are informed by principles developed in the tax theory and policy literature. This Element surveys the policy lessons that emerge from optimal tax analysis since the 1970s. This Element begins with the evolution of tax policy principles from the comprehensive income approach to the expenditure tax approach to normative tax analysis based on social welfare maximization and recounts key results from the optimal income tax analysis inspired by Mirrlees and extended by Diamond to the extensive margin approach. This Element also emphasizes analytical techniques that yield empirically relevant concepts and show the equity-efficiency trade-off at the heart of tax policy. We also extend the analysis to recent literature incorporating involuntary unemployment, and policies like welfare and unemployment insurance.

An economist examines the evolution of optimal tax analysis and its influence on tax policy design.

"From adjusted gross income to zoning and property taxes, the second edition of The Encyclopedia of Taxation and Tax Policy offers the best and most complete guide to taxes and tax-related issues. More than 150 tax practitioners and administrators, policymakers, and academics have contributed. The result is a unique and authoritative reference that examines virtually all tax instruments used by governments (individual income, corporate income, sales and value-added, property, estate and gift, franchise, poll, and many variants of these taxes), as well as characteristics of a good tax system, budgetary issues, and many current federal, state, local, and international tax policy issues. The new edition has been completely revised, with 40 new topics and 200 articles reflecting six years of legislative changes. Each essay provides the generalist with a quick and reliable introduction to many topics but also gives tax specialists the benefit of other experts' best thinking, in a manner that makes the complex understandable. Reference lists point the reader to additional sources of information for each topic. The first edition of The Encyclopedia of Taxation and Tax Policy was selected as an Outstanding Academic Book of the Year (1999) by Choice magazine."--Publisher's website.

G. Galeotti* and M. Marrelli** *Universita di Perugia **Universita di Napoli 1. The economic analysis of optimal taxation has permitted considerable steps to be taken towards the understanding of a number of problems: the appropriate degree of progression, the balance between different taxes, the equity-efficiency trade-off etc .. Though at times considered as abstract and of little use in policy design, the issues it addresses are real ones and very much on the agenda of many countries. As usual in scientific debate, criticisms have contributed to the correct understanding of the theoretical problems involved and made clear that, at the present state of the art, definitive conclusions may be premature. A first well-taken criticism addresses the assumption, underlying optimal taxation models, of a competitive economy with perfect information on the part of individual agents and full market clearing. Once we leave the Arrow-Debreu world, it is no longer necessarily the case that taxes and transfers introduce distortions on otherwise efficient allocations.

"Debates about the optimal structure for tax policies and tax rates hardly cease among public, policy, or academic audiences. These have only grown more heated in the United States as the gap between incomes of the wealthiest 1 percent and the rest of the population continue to diverge. Tax research perhaps has not fully kept pace with the relentless demand of various interests to adjust tax policy. Nonetheless, specialists in the economics of tax policy in recent years have profited from advances in economic theory, econometric measurements, and data quality and access that are beginning to allow a greater consensus on what are the real effects of tax policy and how government levies affect individuals and businesses. The volume edited by Professors Auerbach and Smetters represents an attempt to reduce the lag between the conduct of research on tax issues and its transmission to a broader public. The contributions would explore highly topical issues such as the effects of income tax changes on economic growth, the potential effects of capping certain tax expenditures, the economics of adjusted business tax policy, and environmental tax options. Other essays would investigate perennially important themes such as the conduct of tax administration, the growing role of the tax system on education policy, tax policy toward low-income families, capital gains and estate taxation, and tax policy for retirement savings. A final paper would examine three different options for fundamental tax reform"--
