Meet the 28-Year-Old Grad Student Who Just Shook the Global Austerity Movement

Most Ph.D. students spend their days reading esoteric books and stressing out about the tenure-track job market. Thomas Herndon, a 28-year-old economics grad student at UMass Amherst, just used part of his spring semester to shake the intellectual foundation of the global austerity movement.
Herndon became instantly famous in nerdy economics circles this week as the lead author of a recent paper, "Does High Public Debt Consistently Stifle Economic Growth? A Critique of Reinhart and Rogoff," that took aim at a massively influential study by two Harvard professors named Carmen Reinhart and Kenneth Rogoff. Herndon found some hidden errors in Reinhart and Rogoff's data set, then calmly took the entire study out back and slaughtered it. Herndon's takedown — which first appeared in a Mike Konczal post that crashed its host site with traffic — was an immediate sensation. It was cited by prominent anti-austerians like Paul Krugman, spoken about by incoming Bank of England governor Mark Carney, and mentioned on CNBC and several other news outlets as proof that the pro-austerity movement is based, at least in part, on bogus math.
"I clicked on cell L51, and saw that they had only averaged rows 30 through 44, instead of rows 30 through 49." What Herndon had discovered was that by making a sloppy computing error, Reinhart and Rogoff had forgotten to include a critical piece of data about countries with high debt-to-GDP ratios that would have affected their overall calculations. They had also excluded data from Canada, New Zealand, and Australia — all countries that experienced solid growth during periods of high debt and would thus undercut their thesis that high debt forestalls growth.
Herndon was stunned. As a graduate student, he'd just found serious problems in a famous economic study — the academic equivalent of a D-league basketball player dunking on LeBron James. "They say seeing is believing, but I almost didn’t believe my eyes," he says. "I had to ask my girlfriend — who's a Ph.D. student in sociology — to double-check it. And she said, 'I don't think you're seeing things, Thomas.'"
