Steve Keen’s DebtWatch No 23 June 2008
RBA Assistant Governor Guy Debelle and I spoke at a conference on Subprimes in Adelaide last month. One aspect of my analysis that Guy queried was my emphasis upon the Debt to GDP ratio. He noted that this appeared suspect, because it was comparing a stock (the outstanding level of debt) to a flow (annual GDP).
It’s a valid point to make. The engineer-turned-economist Mickal Kalecki once caustically observed that “economics is the science of confusing stocks with flows”, and I’m a stickler myself for not making that mistake. So making a song and dance about a stock to flow comparison like debt to GDP has to be justified by a sound argument.
