CRS Study on Tax Rates and Growth Still
Flunks the Test
By
Stephen J Entin
Studies issued by the Congressional Research Service are intended to inform the Congress as it develops
public policy and enacts legislation. A recent CRS publication on the effect of the top statutory tax rates on
economic activity may have influenced the debate over taxing the rich during the election and may have
influenced the tax changes just enacted in the fiscal cliff legislation.1
It is critical that such studies reflect the best guidance that the economics and tax professions can provide.
The CRS study on the top tax rates did not meet that high standard. Its original release in the fall was met
with widespread and justified disbelief, and it was withdrawn for review and examination of its
methodology. It has now been reissued in an updated form. However, the re-issued CRS study does not
contain any changes of note that would redeem the original report.
The paper purports to determine the link (or lack thereof) between changes in the top marginal tax rates on
income and capital gains and the growth rate of the economy. Unfortunately, the method used to determine
the relationship depends mainly on timing, looking to see if a change in the growth rate of the economy
coincides with or follows soon after a rise or fall in the tax rates. The study makes no effort to determine the
channels through which the tax changes ought to work to affect the economy, looks at the wrong measure of
progress over the wrong time frame, and takes inadequate account of what other tax or economic events are
occurring at the same time that might mask the results.2
Looking at only part of the picture
Other factors can either hide the effect or exaggerate the effect of tax rate changes. Very few taxpayers have
incomes that reach the top tax rates, and while these people earn a great deal of money, and contribute a
