Due to demographic changes in the workforce, promoting knowledge sharing among employees of different age groups has become increasingly vital. This study aims to examine how age-inclusive human resource practices influence knowledge sharing through the lens of the ability-motivation-opportunity (AMO) framework. The authors conducted a three-wave, time-lagged survey of 647 employees. Using structural equation modeling and mediated moderation analyses, they tested whether employability, developmental motives and age-diversity climate mediate the effect of age-inclusive human resource practices on knowledge sharing, and whether these indirect pathways moderated by employee age. Age-inclusive human resource practices positively predicted knowledge sharing through employability, developmental motives and age-diversity climate. The indirect effect via age-diversity climate was stronger among older employees. In contrast, the indirect effect via developmental motives was weaker among older employees, and the indirect path through employability was not significantly moderated by age. This study contributes to the literature on age-inclusive human resource practices and knowledge sharing by applying the AMO framework to unpack the psychological mechanisms underlying this relationship. By identifying employability, developmental motives and age-diversity climate as key mediators, it offers a more comprehensive understanding of how age-inclusive human resource ...
