Abstract
Previous research on child development advocates that motivating children to make a choice to forfeit their own toys with others develop sharing behavior in later life. Borrowing the conceptual background from the child development theory, this study proposes a model of knowledge sharing behavior among individuals at the workplace. The study proposes a unique conceptual model that integrates the cognitive /behavioral, and other childhood theories to explain the knowledge sharing behavior among individuals. The study uses psychological, cognitive, behavioral and social learning theories to explain the development of altruistic behavior in childhood as a determinant of knowledge sharing behavior. This study develops and empirically tests a research framework which explains the role of childhood experiences in developing altruistic behavior among children and the translation of this altruistic behavior into knowledge sharing behavior later in their professional life. This study explores those relationships using PLS-SEM with data from 310 individuals from Pakistan. The study concludes the role of parents and child-rearing practices as central in developing children's altruistic attitude that leads to knowledge sharing behavior in their later life. The implications and future research directions are discussed in details.
