This paper reflects on the introduction to the new Japanese translation of Luigi Pasinetti’s Keynes and the Cambridge Keynesians. In that introduction, Pasinetti asks his readers to focus especially on his call in the third (and final) section of the book to undertake the creative theoretical work of further developing Keynesian economics. The paper asks who the economists are who are likely to take up this call with special attention to whether libertarian free-market economists can be attracted to this project.
