Christoph Rose provides a broader differentiation of the perspective on family-owned companies. In contrast to several studies that merely discuss family-owned companies and non-family companies, his analysis is based on family influence, so the dominating heterogeneity of family-owned companies in practice is taken into account. The author provides an empirical database that substantiates his statements and that is the first attempt to make the conceptional FIBER model of socio-emotional wealth suggested in literature accessible to empirical analysis.
