The Congressional Research Service has withdrawn an economic report that found no correlation between top tax rates and economic growth, a central tenet of conservative economic theory, after Senate Republicans raised concerns about the paper’s findings and wording. The report questions the premise that lowering the top marginal tax rate stimulates economic growth and job creation.
“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,” the report said. “However, the top tax rate reductions appear to be associated with the increasing concentration of income at the top of the income distribution.”
Romney, the Republican nominee, maintains that any increase in the top tax rates on income and capital gains would slow economic growth and crush the job market’s recovery.
The pressure applied to the research service comes amid a broader Republican effort to raise questions about research and statistics that were once trusted as nonpartisan and apolitical.
Republicans have also tried to discredit the private Tax Policy Center ever since the research organization declared that Mitt Romney’s proposal to cut tax rates by 20 percent while protecting the middle class and not increasing the deficit was mathematically impossible.
