Academic experience has been found to significantly impact on the attitudes and behaviors of managerial decision-makers, which in turn influences corporate strategic decisions. However, the impact of academic decision-makers on corporate ethical decisions, particularly corporate social irresponsibility (CSIR), has yet to receive due attention to date. In this study, we integrate the upper echelons theory and managerial discretion literature to examine whether and when academic CEOs (CEOs with academic experience) influence corporate social irresponsibility (CSIR). First, we suggest that academic CEOs discourage CSIR because they have higher moral standards; thus, their companies are less likely to engage in CSIR activities. In addition, we propose that negative attainment discrepancy (slack resources) reduces (enhances) academic CEOs' managerial discretion to incorporate their ethical preferences into their decisions, thereby weakening (enhancing) the above relationship. This study is the first to examine the relationship between academic CEOs and CSIR. Additionally, the empirical findings of this study offer crucial insights for shareholders and policymakers to prevent or mitigate CSIR effectively.
