Unravelling the determinants of family firms' governance: the family protocol

Purpose Family businesses are essential to the global economy but often grapple with family-related issues, especially during succession. This study explores how governance tools like the family protocol (FP) mitigate conflicts by setting standards for family firm management and continuity. Pioneering the use of game theory and adverse selection setups in family business governance, this research uncovers FP determinants. Design/methodology/approach This research employs game theory and adverse selection setups to delve into the strategic decision-making processes of stakeholders in family firms. The authors break new ground by applying principal–agent theory (PAT) to family business governance structures. This innovative approach uncovers the determinants of the FP, enhancing the authors’ understanding of family firm dynamics. Findings The authors emphasize the importance of custom governance structures, such as the FP, in managing complex family-business interactions. These structures mitigate conflicts and promote smoother transitions during succession, ensuring family firm continuity. This study identifies key determinants, and these results will aid founders, families and practitioners in achieving smoother transitions, ensuring family firm continuity. Originality/value This research pioneers game theory and PAT applications in family business governance, shedding light on the effectiveness of customized governance mechanisms. By identifying FP determinants, the authors contribute to a deeper understanding of family firm dynamics. The findings have practical implications for founders, families, practitioners and consultants, promoting the long-term success and harmony of family firms in the global economy.
