Price theories, the invariable Standard and the notion of 'just' price. My intellectual debt towards Christian

My intellectual debt towards Christian is peculiar: we have been working within the same broad field of analysis, the Classical price theory, though with (partially) different perspectives. I am more inclined to emphasize the differences of the Classical vs the Neoclassical approach; Christian has often tried to reconcile the approaches, by imagining a sort of bridge between Smith, Ricardo, Marx and Arrow-Debreu, through intermediate steps done by Sraffa and Malinvaud. My readings of his works and my conversations with him have thus often included some “dialectical” element. Yet, I have always found in his works a deeper common element: the curiosities and the questions at the basis of his research were similar to the curiosities and the questions I had, and which I tried to give a reply. This, I think, is a most powerful basis by which two minds can come in touch. In what follows, I will outline my view on three topics for which I could benefit from Christian’s ideas.
