We draw upon the socioemotional wealth perspective and the mixed gamble approach to employ a five-year panel dataset of 223 Belgian private family firms to investigate the relationship between family management and growth, with family management ownership, generational involvement, and the CEO's family status moderating this link. We find an inverted U-shaped relationship, with growth reaching its maximum at intermediate levels of family management. Additionally, we demonstrate that family management ownership, generational involvement, and the presence of a family CEO hamper the family management-growth link: all these variables attenuate the positive effect of low to moderate family management, and accentuate the negative impact of high family management. Consequently, our research contributes to a deeper understanding of the relationship between family management and growth.
