Abstract
In the family business system, the family and business subsystems overlap, thereby reciprocally and dynamically influencing each other. When a son- or daughter-in-law enters the family, the equilibrium of the family business system alters in terms of conflicts and emotions. In this study, we embrace family systems theory to conceptually devise how child-in-law entry in the family spurs strategic change in the business subsystem. Building on this speculation, we introduce a multi-level framework of the emotional and relational mechanisms that unfold at the family-business interface. Our study offers insights to family business research, family systems theory, and strategic management, as well as outlining promising directions for future research.
