It is generally assumed that family firms emphasize socioemotional wealth, which exacerbates wealth expropriation from noncontrolling shareholders. We examine this issue in the context of nonfamily shareholders, specifically institutional investors, and find that institutional investors avoid investments in family firms. Furthermore, integrating institutional theory with a socioemotional wealth approach, we find that financial regulation can mitigate external investors’ concerns. These two results are important theoretically because they provide insight into the effect of agency problems specific to family firms and are important for management practice because they can provide guidance for family firms interested in new sources of capital.
