“…The first group of studies explore KS between family members and how exchanges between family members impact the succession process (Bra ¨nnback et al, 2008;Cabrera-Su arez et al, 2001;Cabrera-Su arez et al, 2018) or the capabilities that the firm develops (Chirico andSalvato, 2008, 2016;Fang et al, 2018).
