Board Mix and Women CEOs: What Really Matters

A new study looks at how the mix of people on a company board can shape who becomes its chief executive. It builds on earlier work that said when more women sit on boards, a woman is more likely to be hired as CEO. The researchers split board diversity into three parts: variety, separation and disparity. Variety is simply the number of different kinds of people on a board – age, gender and background. Separation means that the board members have different roles or responsibilities. Disparity refers to how much power or influence each director has.The results show that when a board is diverse in separation, it boosts the chance that a woman will become CEO. On the other hand, if the board is diverse in disparity – meaning power is unevenly spread – it weakens that chance. These findings suggest that simply having a mix of people is not enough; how they work together and share power matters too. The study offers a fresh angle on why some companies still struggle to appoint women at the top, pointing to the importance of balanced roles and influence within the boardroom.
