Timely and authoritative research on the latest issues in tax policy. Tax Policy and the Economy publishes current academic research on taxation and government spending with both immediate bearing on policy debates and longer-term interest. This volume presents new research on taxation and public expenditure programs, with particular focus on how they affect economic behavior. John Guyton, Kara Leibel, Dayanand Manoli, Ankur Patel, Mark Payne, and Brenda Schafer study the disallowance of Earned Income Tax Credit (EITC) benefits as a result of IRS audits, and find that in post-audit years, audited taxpayers are less likely than similar non-audited taxpayers to claim EITC benefits. Janet Holtzblatt, Swati Joshi, Nora Cahill, and William Gale provide new empirical evidence on racial differences in the income tax penalty, or bonus, associated with a couple being married. Haichao Fan, Yu Liu, Nancy Qian, and Jaya Wen evaluate how computerizing value-added tax transactions in China affected the tax revenue collected from large manufacturing firms. Niels Johannesen, Daniel Reck, Max Risch, Joel Slemrod, John Guyton, and Patrick Langetieg study data on the ownership of foreign bank accounts and other financial accounts as reported on income tax returns. They find that many of these accounts are in tax havens, and they discuss the impact of the Foreign Account Tax Compliance Act on tax compliance and government revenue. Louis Kaplow integrates charitable giving into an optimal income tax framework, and shows that the externalities associated with such giving are key to determining its optimal tax treatment. Finally, Roger Gordon compares caps or quantity targets on emissions with carbon taxes and points out that which one dominates can be situation-specific and depend on a number of features of the economy.
