The Congressional Research Service has withdrawn an economic report that found no correlation between top tax rates and economic growth after Senate Republicans raised concerns about the paper’s findings and wording.

The results of the analysis suggest that changes over the past 65 years in the top marginal tax rate and the top capital gains tax rate do not appear correlated with economic growth. The reduction in the top tax rates appears to be uncorrelated with saving, investment, and productivity growth. The top tax rates appear to have little or no relation to the size of the economic pie.
However, the top tax rate reductions appear to be associated with the increasing concentration of income at the top of the income distribution. As measured by IRS data, the share of income accruing to the top 0.1% of U.S. families increased from 4.2% in 1945 to 12.3% by 2007 before falling to 9.2% due to the 2007-2009 recession. At the same time, the average tax rate paid by the top 0.1% fell from over 50% in 1945 to about 25% in 2009. Tax policy could have a relation to how the economic pie is sliced—lower top tax rates may be associated with greater income disparities.
Thomas Hungerford, the CRS researcher who produced the report, said that he had never experienced suppression like this before, and he pushed back on the GOP argument that he had only looked at the effect of tax cuts in the year immediately following enactment. Regardless, he said, Republicans argue that tax breaks for the rich will bring an immediate benefit to the economy, so their criticism is inconsistent. "I checked out three years and then five years and found that no, it doesn't change the results or the conclusion of my paper. So in a way, I find it interesting that they keep talking about the need to lower the top tax rate in order to stimulate the economy now," he said. 'It sounds like they're being a little inconsistent here."
Despite the pressure, Hungerford said he'll continue doing his job in a nonpartisan way. "I'm not going to change. My job is to do economic analysis on issues that the Congress is comparing and quite frankly, I'm going to continue doing that. That's my job," he said.
