This paper presents an overview on recent studies on the role of gender in corporate governance. We study the recent works on the relationship between gender and firms’ financial performance as well as the relationship between gender and firms’ interest in global warming. According to our survey, it appears that firms with the presence of females had more concerns on green gas effects than other male oriented corporations did. Moreover, according to our survey, when a female member joins the board of directors, most investors consider this as a positive signal for profitability. In other words, it appears that the presence of female contributes to firm’s financial performance.
