The Impact of Firm Size on Knowledge Sharing Intra-Firm: A Game-Theoretical Perspective

In this paper, we investigate knowledge sharing between staffers within a firm by iterated prisoner´s dilemma (IPD) gametheoretic model. We find that there is a sub-game perfect equilibrium of knowledge sharing if the threat to sanction the staffer who does not sharing his knowledge with others is credible, the discount factor of future payoff is large enough, and the firm size is less than a threshold. When the firm size is greater than the threshold, the larger the firm size is, the less the second-best level of knowledge sharing is.
