I gave a talk about Modern Monetary Theory (MMT) today at a workshop on Stock-Flow consistent macroeconomics organised at the University of Newcastle by the economics group here. While I hold the research chair in Economics at this university I am not formally part of the economics group – my affiliation is with my research centre (CofFEE) which stands outside the Department/Faculty structure. So it was good to interact with the economics group. It is coincidental because the things I was talking about were being played out in the US and elsewhere (for example, Greece). The US conservatives are now pushing hard for a balanced budget amendment to the US Constitution. If they understood economics they would never consider doing that. If they succeed they will undermine US prosperity forever. It is a case of ignorance undermining prosperity which really describes a lot of what is going on at present in the public debates.
