Shiller on Inequality

Tax Notes Today reports an idea of economist Bob Shiller:

The IRS should be instructed to automatically adjust tax rates to keep economic inequality from getting worse, according to a new proposal outlined by Robert Shiller, a Yale University economics professor.

"We have a serious problem, and it's a problem of growing inequality," Shiller said on December 6 at a Library of Congress discussion in Washington. Shiller developed the proposal with Len Burman, director of the Tax Policy Center, and the two are planning to write a book on the idea.

"We need a standard or principle of income inequality. We don't have one now," he said. Inequality provides motivation to work harder and benefits hard work, hesaid, so "we do want some inequality, but we don't have any clear idea about where we're going and what is appropriate."

The standard, which Shiller calls "inequality indexation" of the tax system, would instruct the IRS to adjust brackets and rates whenever inequality worsened beyond an agreed-on level.

Just to be clear: I do not endorse this proposal. But if you think it is the role of government to contain inequality, then you have to admit that the Shiller plan has a certain logic to it.

Update: Here is the Shiller paper.
