The papers in Volume 29 of Tax Policy and the Economy illustrate the depth and breadth of the taxation-related research by NBER research associates, both in terms of methodological approach and in terms of topics. In the first paper, former NBER President Martin Feldstein estimates how much revenue the federal government could raise by limiting tax expenditures in various ways, such as capping deductions and exclusions. The second paper, by George Bulman and Caroline Hoxby, makes use of a substantial expansion in the availability of education tax credits in 2009 to study whether tax credits have a significant causal effect on college attendance and related outcomes. In the third paper, Casey Mulligan discusses how the Affordable Care Act (ACA) introduces or expands taxes on income and on full-time employment. In the fourth paper, Bradley Heim, Ithai Lurie, and Kosali Simon focus on the “young adult” provision of the ACA that allows young adults to be covered by their parents’ insurance policies. They find no meaningful effects of this provision on labor market outcomes. The fifth paper, by Louis Kaplow, identifies some of the key conceptual challenges to analyzing social insurance policies, such as Social Security, in a context where shortsighted individuals fail to save adequately for their retirement.

This report investigates how tax structures can best be designed to support GDP per capita growth.

How America was Tricked on Tax Policy explains how regular citizens were “tricked” by the outdated view of economists that much heavier taxation of labor rather than capital is economically justifiable. The truth is that workers pay their taxes while the rich pay very little. Based on reputable sources of information, including publications of the Organization for Economic Cooperation and Development (OECD), official statistics data, and the publications in high-ranked journals, the book paves the way for a new policy-making process aimed to achieve more sustainable taxation and to increase the wellbeing of citizens as the main goal of any modern state policy. Dealing with critically important and underexplored topics in tax policy, the book challenges an enshrined dogma that is rarely challenged at the level of policy. In doing so, this book envisions policy changes that could be highly impactful in a new political administration. This book proposes that governments should look for not just corporate income tax rate reduction when announcing their tax reforms but should equally focus on the reduction of the overall tax burden on labor. The negative impact and high social cost of wage taxation is exemplified by the key areas of tax policy that are relevant for every wealthy state, such as taking due care of public health, investing in education and wellbeing of children, and supporting small business for the overall benefit to society. The book compellingly argues how tax policy could be improved by incorporating science and scientific methods.

This paper discusses the theory and practice of tax design to achieve an efficient and equitable outcome, i.e. in support of inclusive growth. It starts with a discussion of the key principles from tax theory to guide practical tax design. Then, it elaborates on more granular tax policy, discussing key choices in the structure of the personal income tax on labor and capital income, taxes on wealth, the corporate income tax, and consumption taxes. The paper concludes by highlighting the political economy considerations of the issues with concrete recommedtions as to how to implement tax reform.

The papers in Tax Policy and the Economy Volume 31 are all directly related to important and often long-standing issues, often including how transfer programs affect tax rates and behavior. In the first paper, Alan Auerbach, Laurence Kotlikoff, Darryl Koehler, and Manni Yu take a lifetime perspective on the marginal tax rates facing older individuals and families arising from a comprehensive set of sources. In the second, Gizem Kosar and Robert A. Moffitt provide new estimates of the cumulative marginal tax rates facing low-income families over the period 1997-2007. In the third paper, Emmanuel Saez presents evidence on the elasticity of taxable income with respect to tax rates, drawing on data from the 2013 federal income tax reform. In the fourth, Conor Clarke and Wojciech Kopczuk survey the treatment of business income taxation in the United States since the 1950s, providing new data on how business income and its taxation have evolved over time. In the fifth paper, Louis Kaplow argues that the reduction in statutory tax rates from base-broadening may not reduce effective marginal tax rates on households.

Edited by Parthasarathi Shome, this Handbook was written primarily for economists who are responsible for analyzing and evaluating economic policies of developing countries at an applied level, and who would benefit from a comprehensive discussion of the concepts, principles, and prevailing issues of taxation.
