This paper outlines and reviews three forms and associated discourses of the 'knowledge economy': the 'learning economy', based on the work of Bengt-Åke Lundvall; the 'creative economy' based on the work of Charles Landry, John Howkins and Richard Florida; and the 'open knowledge economy' based on the work of Yochai Benkler and others. Arguably, these three forms and discourses represent three recent related but different conceptions of the knowledge economy, each with clear significance and implications for education and education policy. (...) The last provides a model of radically non-propertarian form that incorporates both 'open education' and 'open science' economies. (shrink)
