On the Endogeneity of the Margin and Related Issues in Ricardian Economics

As Kenneth Arrow has pointed out in a recent paper, “David Ricardo was a peaceful man” (Arrow 1991, p. 70). Indeed he was—during his lifetime. I am not so sure he is resting peacefully given the further assertion that his system was “a bold attempt to determine values independent of demand considerations” (ibid., p. 75). Arrow adds, byway of qualification, that he does “not think, as some neo-Ricardians seem to, that there was in any sense an intended repudiation of the demand schedule”; rather Ricardo did not conceive of such a schedule even though “some of [his] analysis can only be made sensible on the basis of such a concept.”
