From the abstract:
Recent debates about the nature and desirability of pluralism in economics suffer from a lack of clarity about the meaning of pluralism. This paper attempts to remedy some aspects of this problem by distinguishing between different dimensions of pluralism, that is, epistemological, ontological, methodological, normative and prescriptive dimensions. Although, in principle, these dimensions are distinct, they are difficult to keep apart because of the relations that exist in terms of choices made in the different dimensions. It is argued that the recognition of these distinctions and relations allows for a resolution of some of the debates about pluralism.Read rest here (subscription required), and for an introduction to the symposium by John Davis, see here (subscription required).
