Sustainability Reporting and Corporate Reputation: The Moderating Effect of CEO Opportunistic Behavior

The present study’s main objective is to assess the impact of non-financial sustainability reporting (NFSR) on corporate reputation and the role of the CEO in the opportunistic behavior of companies listed on the Tehran Stock Exchange. In total, 178 firms were assessed for this paper during 2013–2020. In this study for calculating the NFSR, environmental sustainability reporting (ESR), social sustainability reporting (SSR), governance sustainability reporting (GSR) and ethical sustainability reporting (ETSR), Arianpoor and Salehi’s comprehensive and conceptual model has been used. In addition, the literature states that a CEO’s power can be classified as an opportunity for discretion and opportunistic behavior in CEOs that is in contrast with stakeholder demands. To this end, in this study, CEOs’ power has been used as an indicator for the CEO’s opportunistic behavior, and the CEO pay slice (CPS) index was used to calculate the CEO’s level of power. The results revealed that NFSR affects corporate reputation positively. In addition, ESR, SSR, ETSR and GSR positively affect corporate reputation. Moreover, the CEO’s power affects the relationship between NFSR/ESR/SSR/ETSR and corporate reputation. Because managers desire to engage in social and ethical activities, they try to hide the company’s errors and increase its reputation. The results revealed that the CEO’s power did not affect the relationship between GSR and corporate reputation. Since companies in the Tehran Stock Exchange are under intensive supervision, such as in governance, the impact of a CEO’s power and the interaction of a CEO’s power and GSR on company reputation in this study might, thus, not apply to these companies. It is crucial to investigate NFSR, corporate reputation and CEO power within Iran-specific conditions because of differences in emerging markets and developing countries such as Iran, which have diverse ownership structures, economic status, legal systems, government policies, and culture.
