Exploring nonlinear effects of family involvement in the board on entrepreneurial orientation

Family business research suggests that family involvement in the board (FIB) may have both positive and negative effects on entrepreneurship. To reconcile these conflicting views, this study builds on stewardship theory, agency theory, and the resource-based view and proposes a nonlinear relationship between FIB and entrepreneurial orientation (EO) to explore how board task performance moderates this relationship. Using a sample of 208 Belgian private family firms, the findings show an inverted U-shaped relationship between FIB and EO, with EO declining beyond moderate levels of FIB. Furthermore, board monitoring task limits the negative effects of high FIB on EO, whereas the board service task does not have any significant effect. This study offers a more nuanced view of the governance conditions that affect EO in the context of private family firms, an overlooked topic in the family business field.
