Using data from more than 200 firms on the five years following their IPOs -- when boards are typically most influential -- the researchers identified several group-dynamic trends within corporate boards.
First, the researchers found that the more prestigious the existing directors, the more likely they would be to recruit additional prestigious directors because of their natural desire to associate with others like them. Over time, though, the effects of adding additional prestige were shown to diminish, partly because of the impact on group dynamics.
“The addition of a prestigious director has greater potential to be disruptive because it is more likely to affect the current social order,” wrote Pollock and Acharya.
But the researchers also found that boards that have worked together for a long time and have a solidly established working relationship are less likely to perceive a new director as a threat to that social order.
“Serving together for longer periods of time could create clarity and stability in the local social order that decreases the perceived threat of adding a prestigious new director,” they wrote.
Finally, the study found that a high-status CEO’s desire to recruit additional prestigious directors depended largely on the leader’s structural power within the firm. Though perhaps apprehensive about how the addition of a new prestigious director may affect his or her own “relative standing in the board’s status ordering,” those with greater structural and ownership power will be less likely to see the addition as a threat.
“Our analyses … showed that founder-CEOs and CEOs with fewer outsiders on the board were more likely to recruit more prestigious directors, while CEOs that own larger percentages of stock were likely to recruit less prestigious directors,” the researchers wrote.
Their findings will be published in a forthcoming in issue of the Academy of Management Journal.
