Tax Policy and the Economy, Volume 37

Robert A. Moffitt, editor

This volume of Tax Policy and the Economy presents new research on important issues concerning US taxation and transfers.

First, Edward L. Glaeser, Caitlin S. Gorback, and James M. Poterba examine the distribution of burdens associated with taxes on transportation. Replacing the gasoline tax with a vehicle-miles-traveled (VMT) tax would increase the burden on higher-income households, who drive more fuel-efficient cars and are more likely to own electric vehicles. User charges for airports, subways, and commuter rail are progressive, while the burden of bus fees is larger for lower-income households than for their higher-income counterparts.

Next, Katarzyna Bilicka, Michael Devereux, and Irem Güçeri investigate tax shifting by multinational companies (MNCs) and the implications of a potential Global Minimum Tax (GMT). They find that MNCs shift intellectual property to tax havens, and that a large share of patenting activity takes place in tax havens where little or no R&D occurs. Tax havens are particularly important for MNCs with large subsidiary networks; such firms would likely be subject to a GMT.

Mark Duggan, Audrey Guo, and Andrew C. Johnston study the role of experience rating in the Unemployment Insurance (UI) system and find that the current structure stabilizes the labor market because it penalizes firms with high rates of UI-eligible layoffs.

In the fourth paper, David Altig, Laurence J. Kotlikoff, and Victor Yifan Ye calculate how retiring at different ages will affect Social Security benefit amounts, taking into account taxation and other benefits. They find that virtually all individuals aged 45 to 62 should wait until age 65 or later to maximize their Social Security benefits. Indeed, 90 percent would benefit from waiting until age 70, but only 10 percent do so.

Finally, Jonathan Meer and Joshua Witter examine the potential impact of the Earned Income Tax Credit on the labor force decisions of childless adults who are eligible for a small credit after they reach age 25. Comparing labor force attachment changes just before and after this age suggests that the EITC has little impact on the labor force participation of this group.
