Victoria Chick and I contributed a joint paper to the Geoff Harcourt memorial conference in February 2012. It explored Keynes’s conception of a ‘stationary state’ of capitalism and its consequences for variouss concepts of a sustainable economy. In particular, we joined together the notion of an alternative concept of growth, defined as the growth of human capabilities, to those of sustainability, defined as the continuous reduction of material consumption.
We did not complete the paper in time to submit it to the conference volume, but later did manage to complete it and publish it. This version is hence a precursor of the final reference version.
