This study investigates the career development of adolescents with a family business background through a motivational lens. Drawing on self-determination theory, antecedents and consequences of three succession motivations (autonomous, e.g., career interest; introjected, e.g., family obligation; external, e.g., job opportunities) were analyzed in a sample of 152 adolescents in family firms. Structural equation modeling revealed that parental relational support and adolescent's perceived entrepreneurial competence predicted autonomous motivation, whereas parental control related to introjected motivation. Moreover, autonomous motivation related positively to offspring's succession likelihood. Findings point to the relevance of parental career-specific behaviors in the early process of career and succession planning in family firms.
