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.
Casey Mulligan and Greg Mankiw also do not defend CEA’s numbers, but do make use of simple academic abstract models that do not capture the complexities of a policy situation to argue that wage increases could be larger than the tax cut. The inadequacy of their analyses illustrate why well-resourced, team-based institutions with a strong culture of attention to detail like the Congressional Budget Office, the GAO, the Joint Tax Committee Staff or the Tax Policy Center are so important.
Mankiw’s blog is a fine bit of economic pedagogy. It asks students to gauge the impact of a corporate rate reduction on wages in a so called “Ramsey” model or equivalently in a small fully open economy, with perfect capital mobility. Even with these assumptions, he does not get answers in the range of the CEA’s estimates.
As a device for motivating students to learn how to manipulate oversimplified academic models, Mankiw’s blog is terrific as one would expect from an outstanding economist and one of the leading textbook authors of his generation. As a guide to the effects of the Trump administration’s tax cut, I do not think it is very helpful for three important reasons... By far the highest quality assessment of corporate tax issues has been provided by Jane Gravelle, writing under the auspices of the Congressional Research Service. It looks at all the literature. It recognizes that the issues are complex and cannot be captured by a single model or regression equation. It does not start with a point of view. Unfortunately it provides little support for claims that corporate rate cuts will raise revenue, help the middle class or spur rapid wage growth... During my years in government, I served with 7 CEA chairs — Martin Feldstein, Laura Tyson, Joe Stiglitz, Janet L. Yellen, Martin Baily, Christy Romer and Austan Goolsbee. I observed all of them fighting with political figures in their Administrations as they insisted that CEA analysis had to be of a kind that would be respected and validated by outside economists. They refused to cheerlead for Administration policies at the expense of their professional credibility. I cannot imagine any of them releasing an estimate as far from the professional mainstream as $4000 to $9000 wage increase from a corporate rate cut claim. Chairman Hassett should for the sake of his own credibility, that of the Administration he serves and the institution he leads, back off.
Jim Yong Kim, the World Bank’s president, is
trying to revitalize a hidebound institution.
But his embrace of Wall Street is controversial... provides cash to companies in exchange for equity stakes, the World Bank currently drums up more than $7 billion a year from the private sector to invest in ventures in the developing world. Mr. Kim wants that figure to increase eventually to $30 billion... The World Bank promised to protect investors against some losses... those benefiting from the World Bank’s lending practices were “the people who fly in on a first-class ticket to give advice to governments.”.. The argument was that growing investment flows into developing countries rendered World Bank lending mostly superfluous.
.. Last year, the World Bank dispensed $61 billion in loans and investments. By contrast, investors now inject more than $1 trillion a year into emerging markets
.. In effect, he was pitching the bank’s services as a middleman, ready to back projects with guarantees and other incentives. No longer could the World Bank be the sole provider of loans, which, he said, are “crowding out” the private sector.
.. the World Bank economists whose pay is tied to how many loans they churn out
.. “One of the most difficult things to do in a large bureaucracy is to change incentives,
.. “And if you have a large bureaucracy full of economists it is especially hard, because it turns out that economists really hate it when you change the incentives.”
.. On Wednesday, the bank’s top economist, Paul Romer, abruptly resigned.
.. His end came after he claimed, in an interview with The Wall Street Journal, that the World Bank’s closely-watched report on business conditions in different countries had been altered for political reasons.
.. the bank tends to see private sector solutions — those involving the profit motive — as morally questionable.
.. World Bank staffers are used to talking to governments, and now they have to leverage the private sector? It is a different skill set, and flexibility is not the hallmark of development institutions.”
.. “He had to work against his own incentives,” Mr. Kim said, referring to the bank’s practice of rewarding staff for loans. “And that is part of the institutional problem here.”
.. “He has pursued a strategy of making himself popular in Davos by attacking the organization and its staff,” said Lant Pritchett, a retired World Bank executive. “It is this idea that his hand has been hampered by bureaucratic machinations. That may be accepted in Davos — but it’s completely false.”
.. His biggest coup was working with Ivanka Trump
.. They eventually settled in Muscatine, Iowa, where Mr. Kim was a high school quarterback before going on to Brown and securing advanced medical and anthropology degrees from Harvard.
