Game analysis on minimax of honest behaviors in electronic commerce

In electronic commerce, honesty often becomes a major obstacle to a successful trading for both parties involved in the transaction because they don't know each other. This paper applied the Game Tree to describe two types of trading models in electronic commerce, and adopted the method of minimax analysis to analyze both parties' choice strategies in the models. Based on this, some specific conditions and suggestions have been proposed to guarantee that a transaction can be conducted honestly, i.e., a reputation system and the adjustment of certain parameters in the game process with a third party existing can help both parties choose honesty and buying in the transaction.
