In this paper, we examine the relationships between three of the Big 5 personality traits and willingness to justify unethical behavior. We also consider the moderating relationship of four of the GLOBE cultural dimensions on the above relationship. We tested our propositions on a sample of 38,655 individuals from 23 different countries obtained from the latest data available from the World Values Survey Group’s survey. We found that conscientiousness and agreeableness were both negatively associated with willingness to justify unethical behavior. (...) We also conducted Hierarchical Linear Modeling and found significant interaction effects of selected GLOBE cultural dimensions on the relationships between personality traits and willingness to justify unethical behavior. We provide managerial implications of our findings, as well as suggestions for future research. (shrink)
