Rajan’s “The Paranoid Style in Economics”

Raghuram Rajan, soon to be India’s chief central banker, has an excellent piece today dissecting “The Paranoid Style in Economics” and counseling humility for folks engaged in economic policy. A short excerpt:

All of this implies that economic policymakers require an enormous dose of humility, openness to various alternatives (including the possibility that they might be wrong), and a willingness to experiment. This does not mean that our economic knowledge cannot guide us, only that what works in theory – or worked in the past or elsewhere – should be prescribed with an appropriate degree of self-doubt.

But, for economists who actively engage the public, it is hard to influence hearts and minds by qualifying one’s analysis and hedging one’s prescriptions. Better to assert one’s knowledge unequivocally, especially if past academic honors certify one’s claims of expertise. This is not an entirely bad approach if it results in sharper public debate.

The dark side of such certitude, however, is the way it influences how these economists engage contrary opinions. How do you convince your passionate followers if other, equally credentialed, economists take the opposite view? All too often, the path to easy influence is to impugn the other side’s motives and methods, rather than recognizing and challenging an opposing argument’s points.

The whole piece is worth a read.

The Rhetoric of Economic Policy: Inequality vs. Dispersion

Rhetoric matters in economic policy debates. Would allowing people to purchase health insurance from the federal government be a public option, a government plan, or a public plan? Would investment accounts in Social Security be private accounts, personal accounts, or individual accounts? (See my post on the rule of three.) Are tax breaks really tax cuts or spending in disguise? Is the tax levied on the assets of the recently departed an estate tax or a death tax?

In an excellent piece in the New York Times, Eduardo Porter describes another important example, how we characterize differences in income:

Alan Krueger, Mr. Obama’s top economic adviser, offers a telling illustration of the changing views on income inequality. In the 1990s he preferred to call it “dispersion,” which stripped it of a negative connotation.

 In 2003, in an essay called “Inequality, Too Much of a Good Thing” Mr. Krueger proposed that “societies must strike a balance between the beneficial incentive effects of inequality and the harmful welfare-decreasing effects of inequality.” Last January he took another step: “the rise in income dispersion — along so many dimensions — has gotten to be so high, that I now think that inequality is a more appropriate term.”
