Abstract:Although a large proportion of firms are family owned and most family firms are private, our understanding of private family firms is limited. Using confidential information on family relationships between board members, CEOs, and shareholders, this is the first study to provide large-scale evidence on the association between governance structure and firm performance in family-controlled private firms. Our sample is unique as it covers almost all private limited liability firms in Norway, spans 11 years, traces firm ownership to ultimate owners, and identifies family relationship using data on kinship, marriage, and adoption. The results show a U-shaped relationship between family ownership and firm performance. Higher ownership of the second largest owner, higher percentage of family members on the board, stronger family power, and smaller boards are associated with higher firm performance. In addition, the positive association between the ownership of the second largest owner and firm performance also occurs when the second largest owner is a member of the controlling family, but the association is stronger when the second largest owner is a non-family member. We further test the relative importance of these test variables and find that ownership structure is more associated with firm performance than board structure.

This paper studies whether and how Big-4 firms provide higher-quality audits than non-Big-4 firms. Specifically, we first examine a Big-4 effect and then explore three sources of the Big-4 effect. To test the Big-4 effect, we use a unique data set of individual audit partners for a large sample of private companies and a novel research design exploiting the fact that auditees may follow the auditor who switches affiliation from a non-Big-4 firm to a Big-4 firm. Thus, we compare audit quality and audit fees of the same partner–auditee pairs before and after the switch. The results show that the Big-4 effect exists in the private-firm segment. More important, we find evidence for three sources of the Big-4 effect. First, Big-4 firms are able to recruit non-Big-4 partners who deliver higher audit quality than other non-Big-4 partners in the preswitch period. Second, enhanced learning has taken place after the switch. Third, the increased audit quality can also be attributed to stronger incentives/monitoring. These are new findings to the literature.

This is a PDF file of a manuscript that has been accepted for publication in an American Accounting Association journal. It is the final version that was uploaded and approved by the author(s). While the paper has been through the usual rigorous peer review process for AAA journals, it has not been copyedited, nor have the graphics and tables been modified for final publication. Also note that the paper may refer to online Appendices and/or Supplements that are not yet available. The manuscript will undergo copyediting, typesetting and review of page proofs before it is published in its final form, therefore the published version will look different from this version and may also have some differences in content. We have posted this preliminary version of the manuscript as a service to our members and subscribers in the interest of making the information available for distribution and citation as quickly as possible following acceptance.
