Are family firms more optimistic than non-family firms?

Purpose The purpose of this study is to investigate how family ownership affects the disclosure tone of firm earnings press releases. Design/methodology/approach Following prior literature, this study defines family firms as those in which members of the founding families continue to hold positions in top management, to sit on the board or to be blockholders. The disclosure tone of earnings press releases is measured by the level of optimism in firms' earnings announcements using Loughran and McDonald's (2011) word classifications. Multivariate analysis is performed to examine the impact of family ownership on firms' disclosure tone. Additional analysis includes controlling for different firm-level characteristics and using alternative measures of disclosure tone. Findings This study documents that the disclosure tone of earnings announcements is more optimistic for family firms than for non-family firms. The result implies that family owners' large undiversified equity position in their business results in strong incentives for them to issue more positive earnings announcements to maintain high stock performance. Further analysis reveals that the results are mainly driven by family firms with founder CEOs. The results are robust to controls for corporate governance characteristics and to alternative measures of corporate disclosure tone. Originality/value The findings of this study contribute to the literature that examines factors associated with the determinants of the tone in firms' earnings announcements. In addition, this study adds to the extant literature on family firms by providing useful insight into the influence of family control on corporate voluntary disclosure.
