This Element reinvigorates calls to explore avenues to further integrate the research fields of Organization Theory (OT) and Family Business (FB). It presents the family business literature in management journals and categorizes these papers based on four types of theoretical contribution: Embedded, Integrative, Challenger and Generalized. It discusses opportunities for dialogue between FB and OT for each type in three research domains: (i) managing hybridity, (ii) mastering tensions, dualities, and paradoxes, and (iii) modelling time and temporality.
