Reinhart and Rogoff published a paper that appeared to show that public-debt levels above 90% of GDP significantly impede economic growth. Three economists from the University of Massachusetts at Amherst then did what academics are routinely supposed to do – replicate their colleagues’ work and subject it to criticism.
