This study aims to investigate the relationship between bank risk-taking and women on board. We intend to develop and look for the answers to these two questions: (1) What is the relationship between the proportion of gender in board members and risk-taking behavior? and (2) What is the relationship between women on board and risk-taking? Using 1117 bank-year observations data attained from publicly listed banking industries in Asia, the results suggest that Gender diversity of board in credit risk, capital adequacy ratio, and portfolio risk all have a significant negative effect. And more boarder results of the relationship between female directors and bank risk also show a significant and negative effect. Furthermore, the affected a good risk-taking not only comes from the gender diversity on the board but also from female directors that sit in board positions. Therefore, it can be concluded that there is a relationship between women on board and risk-taking behavior.
