The purpose of this study is to examine how psychological entitlement is associated with knowledge hiding behaviors and why some individuals, unlike others, indulge in more knowledge hiding behaviors because of entitlement tendency. Using a time lag study design, we collected data from 241 participants from hospitality sector of Pakistan. The results indicate that psychological entitlement is positively associated with knowledge hiding behaviors and this relationship is mediated by abusive supervision perceptions. Our results also show that hostile attribution bias strengthens the positive impact of psychological entitlement on abusive supervision perceptions. Moreover, the indirect effect of psychological entitlement on knowledge hiding behavior via abusive supervision perceptions is stronger for employees with high levels of hostile attribution bias than employees with low levels of hostile attribution bias.
