摘要:Based on repeated game and unilateral moral hazard framework, this thesis studies the formation and evolution of reputation in C2C E-Market and the restriction effect of reputation to the sellers’ moral hazard behavior. The research on reputation model shows that the formation of reputation is a dynamic process, which is regulated by sellers in C2C E-Market. In the market introducing the reputation mechanism, the most effective way to restrict moral hazard behavior is to leverage the sellers’ long-term benefits, stabilize the market, and reduce transaction cost.
