So-called "Studies" Romney Claims Support Tax Plan Include Blog Posts and Don't Validate His Math

Talking Points Memo digs into Romney's claim that six studies ratify the math of his tax plan.

TPM congressional reporter Sahil Kapur notes:

Of the six studies, two are blog posts by the conservative American Enterprise Institute; one is a report by the Republican-friendly Heritage Foundation; one is a paper by Princeton professor and former George W. Bush adviser Harvey Rosen; the fifth and sixth are a Wall Street Journal op-ed and blog post by Harvard economist Martin Feldstein, an adviser to the Romney campaign.

Moreover, the studies do not reach the same conclusion. Feldstein finds that the math works only if taxes increase on individuals earning between $100,000 and $200,00, which Romney says he won't do. Rosen's analysis omits some of the loss from lower tax revenue and assumes economic growth from the tax cuts alone, something a recent study by the Congressional Research Service found to have little association over the 65 years examined.
