HIGH CORPORATE RATES: RESPONSES FROM THE LEFT

August 20, 2008

The Tax Foundation has begun a push against high corporate tax rates, saying they are bad for the economy and reduce economic competitiveness.

There are two notable responses from left-leaning academic bloggers. One is thoughtful:

Also, if we are mainly concerned about incentive effects, efficiency, and net U.S. national economic welfare, rather than distribution - and I think that is the main long-term issue here, as I'll explain in a moment - then it's not the average but the marginal U.S. corporate tax rate that we care about. So, insofar as companies can play games to save some tax inframarginally, but can't get to zero or boost up their sheltering when they make more profits, it's possible that they would be paying closer to 35% than to their average rates at the margin.

One, not so much:

That's because the statutory rate of 35% is only on paper. Corporations engage in aggressive tax planning that cheats the system, and they take advantage of a bountiful number of lucrative loopholes built into the system under the four decades of Reagan-style corporate favoritism and deregulation, including items such as accelerated depreciation, various expensing provisions that let corporations deduct before they really have an economic cost, and the lucrative research & development credit that lowers taxes dollar-for-dollar for R&D expenditures that corporations have to do anyway (so they do not serve as an incentive to greater development) and that corporations have often already done prior to the enactment of the one-year "extensions" of the credit that have been taking place as transitions to no-credit for years.

Some academics engage the system as it exists and struggle to find answers to real problems in tax and economics. Others go forth to do battle with Scrooge McDuck.
