Sustainability Reporting in Family Firms: A Panel Data Analysis

We analyze the largely unexplored differences in sustainability reporting within family businesses using a sample of 230 non-financial Italian listed firms for the period 2004-2013. Drawing on legitimacy theory and stakeholder theory, integrated with the socio-emotional wealth (SEW) approach, we study how family control, influence and identification shape a firm's attitude towards disclosing its social and environmental behavior. Our results suggest that family firms are more sensitive to media exposure than their non-family counterparts and that family control enhances sustainability disclosure when it is associated to a family's direct influence on the business, by the founder's presence on the board or by having a family CEO. In cases of indirect influence, without family involvement on the board, the level of family ownership is negatively related to sustainability reporting. On the other hand, a formal identification of the family with the firm by business name does not significantly affect social disclosure.
