Information asymmetry in CSR reporting: publicly-traded versus privately-held firms

Purpose This paper aims to investigate the motivations behind the publication of corporate social responsibility (CSR) reports, and particularly the effect of information asymmetry between firms and their owners. Design/methodology/approach A natural experiment contrasting the CSR reporting of private vs public firms is used to test whether the degree of information asymmetry is a significant factor in the decision to publish CSR reports. Using a hand-collected sample of the 239 largest US private companies matched with publicly-traded firms, the effect of these inherently different information environments on CSR reporting is tested through logistic regression. Factors suggested by stakeholder and legitimacy theories are tested for their differential impact on private vs public firms’ decisions to publish a CSR report. Findings Results indicate that private firms are less likely to publish a CSR report than similar public firms. Public firms also follow Global Reporting Initiative guidelines more frequently, consistent with signaling report quality to dispersed investors. A subsample of private companies facing greater information asymmetry is found to be similar to public firms in their reporting behavior, reinforcing the link between information asymmetry and CSR disclosure. Further analysis suggests that non-owner stakeholders play an important role in private companies’ CSR reporting decisions. Practical implications In addition to accounting and governance scholars, the findings should interest private firm managers preparing for an initial public offering (IPO), as the evidence suggests that CSR reporting is used to communicate information to dispersed investors. The insight into reporting motivations should be useful to accountants engaged in CSR consultation and assurance. Social implications With the growing attention paid to the CSR performance of firms, demonstrated by the growth in socially responsible investing, the study provides evidence that effective communication of CSR information to investors may play a key role in CSR-engaged firms’ disclosure strategies. Originality/value To the best of the author’s knowledge, this study is the first to analyze the CSR reporting decisions of a large sample of publicly-traded and privately-held firms. The results add to our understanding of what motivates firms to publish CSR reports, highlighting the importance of information asymmetry between the firm and its owners.
