One Last Time on Who Benefits From Corporate Tax Cuts

I recently asserted that Kevin Hassett deserved a failing grade for his “analysis” projecting that the Trump administration proposal to reduce the corporate tax rate from 35 to 20 percent would raise the wages of an average American family between $4,000 to $9,000. I chose harsh language because Hassett had, for what seemed like political reasons, impugned the integrity of people like Len Burman and Gene Steuerle who have devoted their lives to honest rigorous evaluation of tax measures by calling their work “scientifically indefensible” and “fiction.” Since there have been a variety of comments on the economics of corporate tax reduction, some further discussion seems warranted.

The analysis from Hassett, chief of the White House Council of Economic Advisers (CEA), relies heavily on correlations between corporate tax rates and wages in other countries to argue that a cut in the corporate tax rate would boost returns to labor very substantially. Perhaps unintentionally, the CEA ignores our own historical experience in their analysis. As Frank Lysy noted, the corporate tax cuts of the late 1980s did not result in increased real wages. Actually, real wages fell. The same is true in the United Kingdom, as highlighted by Kimberly Clausing and Edward Kleinbard. These examples feel far more relevant to the corporate tax issue analysis than comparisons to small economies and tax havens like Ireland and Switzerland upon which the CEA relies.

There has been a lot of back and forth, but notably no one has defended the $4,000 claim as a “very conservatively estimated lower bound,” let alone endorsed the plausibility of the $9,000 claim. In fact, the Wall Street Journal op-ed page published two very optimistic versions of what the wage increase could be, which were below CEA’s lower bound.
