Zusammenfassung:
This thesis investigates the influence of elite supervisory board members on the performance of German firms. Following the transformation of the German business landscape post-reunification, elite board members, characterized by their exceptional social capital, continue to play a crucial role. Using resource dependence theory, the study explores the link between board members' social capital and firm performance. Leveraging a yearly ranking of the top 30 most powerful supervisory board members to identify elite members, this thesis analyses their influence on firm performance. Contrary to expectations, the results show a significant negative impact of elite board members on accounting-based performance and no significant effect on market-based performance. The expected stronger effect of having an elite board chair was not supported. These findings encourage a reevaluation of the assumed benefits of elite board membership, suggesting underlying complex dynamics. The thesis concludes with implications for corporate governance, limitations of the study, and directions for future research.
