When historians look back on the meltdown of 2008 they will conclude that the country that triggered it – the US – was among the least bad in its continuing monetary and in its initial fiscal response. What a frustration, then, that the US finds itself endlessly relitigating the debate between Keynesians and anti-Keynesians.
In the past few weeks, the intellectual tide has turned sharply towards the former following revelations of errors by Kenneth Rogoff and Carmen Reinhardt. This has been assisted by the IMF’s change of heart about the merits of short-term stimuli. Moreover, austerians, such as Niall Ferguson, the Harvard historian, continue to aid their own discrediting by dredging up the canard about John Maynard Keynes’s “childless vision” – linking his homosexuality to an alleged reckless disregard for the long term.
Yet for all the academic sound and fury, US politics is unchanged and apparently unchangeable: mild fiscal contraction is set to dilute the US recovery for at least another year. Democrats are impotent against Republican stonewalling in the House of Representatives. And Republicans can do nothing about Barack Obama’s veto – or Democratic control of the Senate. Which means we are condemned to at least another year of hypothetical fiscal debates. Here, vindicated though they may be on counter-cyclical fiscal policy, Keynesians are guilty of sins of omission.
