While the moral argument for gender diversity has already been made and is incontestable, and more and more economical arguments have been brought to support the business case for the presence of women on the boards of directors of publicly listed companies, the bottom-line issue of what kind of impact gender diverse boards have on firm financial performance is still unclear. The aim of this paper is to deliver a comparative analysis of the impact of gender diverse boards on firm financial performance in France and Romania. Our results do not to provide any evidence of a link between boards’ gender diversity and companies’ financial performance, but while the analysis has failed to find a positive link between female presence and firm financial performance, it has not outlined a negative one.
