Corporate Social Performance, Firm Size, and Organizational Visibility: Distinct and Joint Effects on Voluntary Sustainability Reporting

This study investigates the distinct and joint effects of corporate social performance (CSP), firm size, and visibility on a company’s decision to disclose sustainability-related information through sustainability reports. It seeks to provide more nuanced explanations for why certain companies tend to extensively report on their sustainability performance. First, while prior studies have predominantly focused on environmental reporting, the current analysis considers comprehensive sustainability reports that include both environmental and social issues. Second, the article argues that the effects of two important antecedents of legitimacy pressure—firm size and organizational visibility—should be analyzed separately rather than restricting the analysis on the effects of legitimacy pressure per se. Third, it argues that the hypothesized effects are nonlinear because the marginal costs and benefits of sustainability reporting vary with a company’s CSP level, its size, and its visibility in the public. Finally, although there is a strong link between CSP and sustainability reporting, the strength of this link depends on its size and visibility. The study of 280 companies in environmentally and socially sensitive industries provides considerable support for these hypotheses, including evidence that size and visibility independently affect sustainability reporting and that the shape of the CSP/sustainability reporting link is contingent upon firm size and visibility.
