The organizations need to find ways of motivating employees to share proprietary knowledge. Failure to do so may render even the most technologically advanced and powerful KM systems useless as employees hoard valuable knowledge rather than contributing to this system. The present study investigated the impact of situational and dispositional factors on employees’ willingness to share knowledge. Specifically, we examined the effectiveness of explicit incentives for increasing employees’’ willingness to share knowledge, considering both tangible and intangible incentives. We also examined the moderating role of employee impression management on the effects of these incentives. We approach these issues by regarding knowledge sharing as a form of organizational citizenship behavior, thus situating this research in a well-developed literature.
