This paper concerns the influence of gender on a firm’s moral and economic performance. It supports Thomas White’s intimation of a male gender bias in the value system underlying extant business theory. We suggest that this gender bias may be corrected by drawing on the concept of substantive rationality inherent in virtue-ethics theory. This feminine-oriented relationship-based value system complements the essential nature of the firm as a nexus of relationships between stakeholders. Not only is this feminine firm morally desirable, but (...) it is also economically more efficient in that trust becomes a more feasible implicit contractual enforcement mechanism. In an organizational context, therefore, from both a moral and an economic perspective, long established economic man is dominated by nascent economic woman. (shrink)
