Bill Mitchell (August 13, 2010), "Michal Kalecki – The Political Aspects of Full Employment": "... those scholars who do not see Keynes as being the central figure in the development of the theory of effective demand ... lean to the view that the transition from the Treatise (1930) to the General Theory (1936) was so great that it is likely that Keynes knew what Kalecki had written and published and was influenced by it."
