Knowledge sharing is crucial for organizational success, fostering innovation and efficiency. This study extends the Theory of Planned Behavior (TPB) by incorporating reciprocity, perceived loss of power, effort to codify knowledge, organizational rewards, and trust as factors influencing knowledge-sharing intentions in Thailand. However, reciprocity, loss of power, and effort to codify knowledge did not impact intentions to share either implicit or explicit knowledge. The espoused national cultural values of high-context communication and power distance indirectly and significantly impact these intentions through attitude and trust as mediators. The findings underscore the importance of understanding cultural nuances to enhance strategies for effective knowledge sharing.
