The world of economics has just changed, and somebody has some 'splaining to do! Please savor the following twisted tale of bad math, academic folly and pundit hubris.
Since 2010, the names of Carmen Reinhart and Kenneth Rogoff have become famous in political and economic circles. These two Harvard economists wrote a paper, “Growth in the Time of Debt” that has been used by everyone from Paul Ryan to Olli Rehn of the European Commission to justify harmful austerity policies. The authors purported to show that once a country's gross debt to GDP ratio crosses the threshold of 90 percent, economic growth slows dramatically. Debt, in other words, seemed very scary and bad.
Their historical data appeared impressive, as did their credentials. Policy-makers and journalists cited the paper to convince the public that instead of focusing on the jobs crisis that was hampering recovery, we should instead focus on deficits. The deficit hawks jumped up and down with excitement.
Herndon, Ash, and Pollin have set off a firestorm, with those who long suspected that R&R's work was crap shouting hallelujah and defenders scrambling to figure out a way to support deficit hysteria [6] despite the body blow to their theory.
Bottom line: The foundation of the entire global push for austerity and debt reduction in the last several years has been based on a screwup in an Excel spreadsheet and poorly constructed data.
Reinhart and Rogoff are on the defensive. As Mathew O'Brien at The Atlantic put it, "this is the academic's version of the dream where you're naked in public." They have screwed up royally. They have also done a great deal of damage to the world. As Paul Krugman has observed, their replies to their critics have thus far only compounded the confusion. They need to come clean, stop talking like their mistakes are minor, and own up to the enormity of their errors. And a big round of applause goes to the folks at U Mass Amherst for getting to the bottom of this insanity.
