This document discusses gender diversity in boardrooms and firm performance. It begins by defining gender diversity in boardrooms as the presence of women on corporate boards of directors. Previous research has found that gender diversity can influence board functioning and firm performance. The aim of the study is to contribute evidence on the relationship between gender diversity and firm performance in Pakistani companies. It measures gender diversity as the percentage of women on the board and firm performance using return on assets and return on equity. Regression analysis finds that the percentage of women directors explains 97-97.6% of the variations in return on assets and return on equity, suggesting a significant relationship between gender diversity and firm performance.
