PurposeDrawing on social exchange theory, this study aims to investigate the reciprocal relationship between an employee's knowledge sharing and his or her coworkers' responses to this focal contributor in terms of knowledge sharing and helping behaviors.Design/methodology/approachA two-wave online survey collected data from 84 respondents who provided ratings on each member on their team, representing 440 dyadic relationships. Hierarchical linear modeling analyzed the between-subjects and within-subject data simultaneously.FindingsEmployees generally reciprocate contributors' knowledge sharing with an exact act (i.e. knowledge sharing) through the mechanism of peer respect. However, respect generated by knowledge sharing is enhanced only when the knowledge contributor is competent.Originality/valueResearch on how an employee's knowledge sharing actually influences other members of a team is lacking. This study addresses this gap by examining responses to a team member's knowledge sharing from a peer's perspective. It also reveals when knowledge sharing is more pronounced in earning peer respect.
