Simulating the Economic Effects of Romney's
Tax Plan
By
Stephen Entin & William McBride, PhD
Introduction
The debate over Mitt Romney's tax plan has largely revolved around the short term concerns of who gets
what and how much, rather than the more long term concerns of economic growth, job creation, deficit
reduction, and tax reform.1 This is unfortunate, especially in a time of record unemployment and debt
levels. These serious issues have been put aside to focus particularly on the results of a single study by the
Tax Policy Center (TPC),2 which finds Romney's tax plan would require raising taxes on low- and middle-
income earners to pay for tax cuts for high-income earners. However, to get there, TPC assumes that tax
rates do not matter for economic growth, i.e., Romney's plan to cut income tax rates by 20 percent across
the board will have no effect on labor supply or saving and investment decisions. Only among Washington
score keepers does such an assumption make sense, but it certainly has no credibility among academic
economists.3
Economists recognize that there is more to a tax cut than the immediate increase in wealth of the recipient.
There is a change in incentives because there is a change in the law. If investment taxes are lowered,
investment increases, because investors expect to keep more of their after-tax returns, and more people
become investors. If taxes on wages are lowered, more people work and more people work harder. The
benefits from these things spill over beyond the immediate actors. Businesses invest in equipment and new
hires, leading to more productive workers, higher wages, and ultimately satisfied customers. If this is trickle
