Former audit demand studies generally consider wholly family-owned private firms as a homogeneous group of firms that incur minimal agency costs. Family firm literature, however, argues that these firms might incur significant agency costs as well and we therefore examine audit demand in this particular type of firms. As we examine private family firms from the US, which have no audit requirement, we broaden the concept of audit demand to the demand for auditor services, which encompasses audits, reviews and compilations. Consistent with former audit demand studies, we hypothesise a negative association between management ownership and the demand for auditor services but only for first generation private family firms. We hypothesise that this relation turns positive for subsequent generation private family firms due to entrenching behaviour caused by weakened altruistic feelings between the family shareholders. Our results support this hypothesis but only regarding the demand for reviews and compilations. Therefore, our findings suggest that reviews and compilations seem to be sufficient and more cost-effective in this specific context to mitigate shareholder-manager agency costs compared to more expensive audits.Moreover, results suggest that the level of shareholder-debtholder agency costs do seem to be a driver for the demand for audits.
