We examine whether family firms are more likely to use Big 4 auditors compared to non-family firms. The literature indicates two perspectives. On the one hand, Big 4 auditors can alleviate problems of information asymmetry. On the other hand, Big 4 auditors can constrain insiders in their pursuit of private gains. We find that family firms are less likely to use Big 4 auditors. This supports the second perspective. We also find that our result is sensitive to the definition of family. We consider two definitions in our study: a family-centric one (two or more insiders are family members or affiliates) and a founder-centric one (founder or member of founding family is an insider). Our result is robust only if we use the family-centric definition.
