The Promise on Marketing Service and Its Credit Mechanism Design

摘要

This paper considers a sort of promise on marketing service for the seller in the complete competition market, and establishes one model to reveal the information of the products quality and to meet the participation constraint and the incentive compatibility constraint. Both sides of trade have enthusiasm to participate in this mechanism and not to deceive the opposite side. It shows that the enterprises with high-quality products be willing to accept this mechanism to transfer signals which reveal the high quality of their products, and those with low-quality products fail to follow it because no profit will be taken to them. With symmetry information in this mechanism, the buyer will get the same expectation utility if the exchange can be carried out.
