When Policy Meets Statistics: The Reinhart and Rogoff Study on Excessive Debt

Knowing how many of us economists toil away in obscurity on most research, I’m always intrigued by what catches the press’s and public’s attention. Take, for example, the significant attention paid to a 2010 study by Harvard economists Carmen Reinhart and Kenneth Rogoff that concluded that countries with debt levels above 90 percent of GDP began showing slower rates of growth. When Thomas Herndon, Michael Ash and Robert Pollin, scholars at the University of Massachusetts at Amherst, recently had trouble replicating Reinhart and Rogoff’s results, the debate played out in national news outlet.

Unfortunately, this discussion quickly devolved from substance to politics to arguments ad hominem. Without getting into the extent to which I or others can validate Reinhart and Rogoff’s (R&R’s) original findings, I offer six cautions for anyone witnessing this or a similar statistical debate with significant policy implications.

Getting the Facts Straight on Retirement Age

On the front page of the Washington Post on March 11, 2013, Michael Fletcher connects different the life expectancies of the poor and rich to the debate over whether Social Security should provide more years of retirement support as people live longer. He mistakenly leaves the impression that adjusting the retirement age for increases in life expectancy hurts the poor the most. In fact, such adjustments take more away from the rich. Let me explain how. Continue reading

Violence in America: The Wider Conversation

In the aftermath of Newtown and, by one estimate, 25 mass shootings since 2006, the country is engaged in an intense fight over assault-like weapons and the right of Americans to carry them. While I consider it downright stupid and outright dangerous to allow people to buy, sell, and carry around the equivalent of small machine guns—imagine how safe you would feel if all your loony neighbors touted one around—I wish we were engaged in a much wider and thoughtful discussion over violence in America and how to reduce it.

Our Imperfect Work

“We must act, knowing that our work will be imperfect,” Barack Obama proclaimed in his second inaugural address. Interestingly, the Washington Post blazoned its front page with the first three words without noting the succeeding dependent clause. Yet within this clause, I believe, lies the means by which the president—and Congress—and we—can move past so many of our conflicts and face up to the problems that confront us. The solution lies not in acting, but in recognizing the imperfection of what we do. If our budgets are to be vehicles for change, then we cannot enact so many laws as if the priorities of one time and place must endure forever. Continue reading

An Extremely Mucked Up Medicare Debate

Medicare is taking on a primary role in the presidential race. The discussion often turns to whether the program should continue in its current form, with more direct government controls over costs, or shift its emphasis to vouchers or premium support plans. Let’s try to set the record straight. Continue reading

Aurora: Giving Mass Murderers the Rewards They Seek?

While we can’t totally prevent the type of tragedy that has taken place in Aurora, Columbine, Virginia Tech, and Oklahoma City, we can certainly reduce the probability of such events reoccurring.

While these mass murderers may have multiple delusions, almost all seek publicity, copy what they have seen elsewhere, or, often, both. Their final actions, as well as how much of their earlier life revolves around elaborate preparations, clearly give them some bizarre sense of identity. Then, when they carry out their plans, they are rewarded instantaneously with the fame they could not otherwise receive. Reduce the attention given to them, and you reduce the likelihood future people with this type of mental illness will seek violent outlets for their distorted worldviews. Continue reading
