Abstract
Purpose This paper explores how the tension between a firm's CEO overconfidence feature and externally observable hubris attribute may determine the level of corporate sustainability performance. This work also contemplates the impact of the moderator "corporate governance practices." Design/methodology/approach This study uses a sample of 658 firm-year-observations using a sample of European real estate firms indexed on Stoxx Europe 600 Index from 2006 to 2019. To test the developed hypotheses, feasible generalized least square (FGLS) regression is applied. Findings Findings suggest that a good corporate governance score strengthens the positive effect of the psychological bias (CEO overconfidence) on corporate sustainability performance while it fails to attenuate the negative effect of the cognitive bias (CEO hubris). Research limitations/implications The research provides an overview of the impact of CEO personality traits on the corporate sustainability performance level in the European real estate sup-sector. As corporate governance can have a major impact to control these traits, the authors recommend European real estate companies to improve their corporate governance practices. Originality/value This study contributes to the existent literature this gap with two empirical novelties: (1) providing a novel insight into sustainability involvement using a sample of European real estate sup-sector and (2) investigating the moderating effect on the link between CEO psychological and cognitive biases and sustainability performance. This study provides empirical evidence that entrenchment problems arising from CEO hubris would not be mitigated by a good corporate governance practice.
