Revisiting Speculative Hyperinflations in Monetary Models: A Reply to Cochrane. Kenneth Rogoff, May 17, 2015, Paper, "This paper revisits the debate on ruling out speculative hyperinflations in monetary models. Obstfeld and Rogoff (1983, 1986) argue that in pure fiat money models, where the government gives no backing whatsoever to currency, there is in fact no reasonable way to rule out speculative hyperinflations where the value of money goes to zero, even if the money supply itself is exogenous and constant. Such perverse equilibria are ruled out, however, if the government provides even a very small real backing to the currency, indeed the backing does not have to be certain. Cochrane (2011)," Link
