Purpose: The purpose of this paper is to investigate the cross-cultural impact of CEO-Chair’s gender to the likelihood of CEO duality firm’s bribery. Design/methodology/approach: Hierarchical linear modeling was used to analyze data of 5,837 CEO duality firms from 21 countries. Findings: Firms with male CEO-Chairs were found to have higher propensity to bribe than their female counterparts. Moreover, cultural values of institutional collectivism and performance orientation strengthened gender’s impact to bribery. In contrast, future orientation weakened the gender-bribery relationship, as opposed to the proposed effect. Practical implications: Key findings of this study can be utilized to increase awareness and widen perspective on the roles of CEO-Chair’s gender and national culture on bribery. These can also be useful in the selection of CEO-Chair, design of educational programs on ethics as well as government and non-governments’ programs and policies to minimize incidents of bribery. Originality/value: There are no existing studies on CEO duality firm’s bribery which performed cross-cultural analysis on the impact of CEO-Chair’s gender, making the study a novel contribution to business ethics, organizational structure, corporate governance, management decision, transparency, and accountability.
