Whether family firms are more likely to disclose voluntarily is an empirical issue. In this paper we examine whether family firms are more likely to provide conference calls in comparison with non-family firms. We also argue that the propensity of family firms in Taiwan to provide conference calls is affected by two characteristics, namely, (1) the divergence between controlling shareholders' control rights and cash flow rights and (2) family integrity, which are the unique features of family firms that affect business prospects. We find that family firms are more likely to hold conference calls regardless of the kind of information disclosed. However, further analyses show that family firms facing agency problem due to the conflicts between controlling and minority stockholders exhibit a lower likelihood of providing a conference call. In addition, low-integrity family firms, measured via negative media coverage, are less likely to hold a conference call and have lower conference call frequency.
